Below is a selection from a popular science book.
If blood is red, why are veins（静脉） blue?
Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it’s outside the body, when it’s sitting in the vein near the surface of the skin, it’s more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.
Which works harder, you heart or your brain?
That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.
Why do teeth fall out, and why don’t they grow back in grown-ups?
Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall our when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they are gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off.
Do old people shrink as they age?
Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They lose height as their spine（脊柱） becomes shorter and more curved due to disuse and the effect of gravity(重力). Many (but not all) men and women do lose height as they get older. Men lose and average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards ----- their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved.
Why does spinning make you dizzy（眩晕的）?
Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you’removing while you’re not.
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area ----- from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on this planet.
If exercise wears you out, how can it be good for you?
Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy, it’s more that a lack of exercise leaves your body weak and easily affected by diseaseWhat is the color of blood in a vein near the surface of the skin?
| A．Blue | B．Light yellow |
| C．Red | D．Dark reddish purple |
Why do some old people look a little shrunken as they age?
| A．Because their spine is in active use. |
| B．Because they are more easily affected by gravity. |
| C．Because they keep growing backwards. |
| D．Because their spine becomes more bent. |
Which of the following statements about our brain is true?
| A．In the long run, our brain probably works harder than our heart. |
| B．When our brain senses the spinning, we will feel dizzy. |
| C．The brains of the other mammals are as complex as those of humans. |
| D．Our feelings and emotions come from the most developed area in our brain. |
What is the main purpose of the selection?
| A．To give advice on how to stay healthy. |
| B．To provide information about our body. |
| C．To challenge new findings in medical research. |
| D．To report the latest discoveries in medical science. |
Some people will do just about anything to save money. And I am one of them. Take my family's last vacation. It was my six-year-old son's winter break form school, and we were heading home from Fort Lauderdale after a weeklong trip. The flight was overbooked, and Delta, the airline, offered us $400 per person in credits to give up our seats and leave the next day. I had meeting in New York，So I had to get back . But that didn't mean my husband and my son couldn't stay. I took my nine-month-old and took off for home.
The next day my husband and son were offered more credits to take an even later flight. Yes, I encouraged一okay, ordered-them to wait it out at the airport, to "earn" more Delta Dollars. Our total take: $1,600. Not bad, huh?
Now some people may think I'm a bad mother and not such a great wife either. But as a big-time bargain hunter, I know the value of a dollar. And these days, a good deal is something few of us can afford to pass up.
I've made living looking for the best deals and exposing (揭露) the worst tricks . I have been the consumer reporter of NBC's Today show for over a decade. I have written a couple of books including one titled Tricks of the Trade: A Consumer Survival Guide. And I really do what I believe in. I tell you this because there is no shame in getting your money's worth. I'm also tightfisted when it comes to shoes, clothes for my children, and expensive restaurants. But I wouldn't hesitate to spend on a good haircut. It keeps its longer, and it's the first thing people notice. And I will also spend on a classic piece of furniture. Quality lasts.

Spring is here and so is the cycling season. Here are some tips on how to do it safely and comfortably.
Watch your feet—Pushing with the wrong part of the foot can raise your risk of developing a painful injury of the heel and arch（脚心）, says Rob Werstine, a sports physiotherapist（理疗师）and board member of the Canadian Physiotherapy Association. You should push with the ball of your foot, he says.
Layer up—While it’s still cool, wear layers of clothing, with clothing close to the body that breathes and outer layers that do not absorb water. Go for bright colors that increase your visibility（可见度）.
Be reasonable—If you are just starting out and aren’t in good shape, don’t sign up for a 50-kilometre ride. And while cycling is great exercise for people who want to get into shape, if your doctor advises you not to do tiring exercise, cycling shouldn't be your starting position, Werstine says. Walk to begin getting into shape and then graduate to cycling.
Fix the fit—If you develop lower back pain or numbness in your hands and fingers from cycling, it could be your bike isn’t adjusted properly for your height. A good cycle shop can help you find the right height for the seat and handlebars, but if you have continuing problems, consider consulting a bike fit physiotherapist, Werstine says.
Be mindful—You have to pay attention on the roads to vehicles, other cyclists and pedestrians（行人）.Consider taking a cycling safety course to practise your skills. Or do some reading about how to avoid dangerous cycling situations. bicyclesafe.com, for instance, lists 10 types of car-bike accidents and how to avoid them.Which part of the foot should one use when cycling?
| A．The heel. | B．The arch. | C．The ball. | D．The toes. |
From Paragraph 4 we can conclude______.
| A．not everyone can exercise by cycling | B．walking is better than cycling |
| C．cycling is popular with people | D．cycling is helpful to everyone |
According to the last paragraph, if you want to avoid danger when cycling, you should ______.
a. consider taking a cycling safety course
b. search for information on bicyclesafe.com
c. consider consulting a bike fit physiotherapist
d. adjust the bike properly for your height
| A．a. c | B．c. d | C．a. b | D．b. d |
A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.
“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.
They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.
While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.
Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”
(392 words)The difficulty the team of engineers met with while making the robotic fly was that __________.
| A．they had no model in their mind |
| B．they did not have sufficient time |
| C．they had no ready-made components |
| D．they could not assemble the components |
It can be inferred from paragraphs 3 and 4 that the robotic fly __________.
| A．consists of a flight device and a control system |
| B．can just fly in limited areas at the present time |
| C．can collect information from many sources |
| D．has been put into wide application |
Which of the following can be learned from the passage?
| A．The robotic flyer is designed to learn about insects. |
| B．Animals are not allowed in biological experiments. |
| C．There used to be few ways to study how insects fly. |
| D．Wood’s design can replace animals in some experiments. |
Which of the following might be the best title of the passage?
| A．Father of Robotic Fly |
| B．Inspiration from Engineering Science |
| C．Robotic Fly Imitates Real Life Insect |
| D．Harvard Breaks Through in Insect Study |
Here is an astonishing and signficant fact:Mental work alone can’t make us tired. It sounds absurd. But a few years ago, scientists tried to find out how long the human could labor without reaching a stage of fatigue(疲劳). To the amazement of these scientists, they discovered thett blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day labourer, we could find it full of fatigue toxins(毒素) and fatigue products. But if we took blood from the brain of Albert Einstein, it would show no fatigue toxing at the end of the day.
So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours f efforts as at the beginning. The brain is totally tireless. So what makes us tired.
Some scientists declare that most of our fatigue come from our mental and emotional(情感的) attitudes. One of England’s most outstanding scientists. J. A. Hadfield,says,“The greater part of the fatigue from which we suffer is of mental origin. In fact,fatigue of purely physical origin is rare.” Dr. Brill, a famous American scientist, goes even further. He declares,“One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems.”
What kinds of emotions make sitting workers tired?Joy?Satifaction?No!A feeling of being bored,anger,anxiety,tenseness,worry,a feeling of nt being appreciated---those are emotions that tire sitting workers.Hard work by itself seldom causes fatigue.We get tired because our emotions produce nervousness in the body.What surprised the scientists a few years ago?
| A．Fatigue toxinscould hardly be found in a labour’s blood. |
| B．Albert Eistein didn’t feel worn out after a day’s work. |
| C．The brain could wrk for many hours without fatigue. |
| D．A mental worker’s blood was filled with fatigue toxins. |
According to the authour,which of the following can make sitting worker tired？
| A．Challenge mental work. |
| B．Unpleasant emotions. |
| C．Endless tasks. |
| D．Physical labor. |
What’s the authour’s attitude towards the scientists’ ideas?
| A．He agrees with them. |
| B．He doubts them |
| C．He argues against them. |
| D．He hesitates to accept them. |
We can infer from the passage that in order to stay energic, sitting workers need to ______.
| A．have some good blood |
| B．enjoy their work |
| C．exercise regularly |
| D．discover fatigue toxin |
While Jennifer was at home taking an online exam for her business law class, a monitor（监控器）a few hundred miles away was watching her every move.
Using a web camera equipped in Jennifer’s Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked - remotely - to prevent Internet searches , and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down?
In the battle against cheating, this is the cutting edge and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid - that students haven’t just searched the Internet to get the right answers.
Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses." Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.
Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students’ identities using personal information, such as the telephone number they once used.
Other programs can produce unique exam by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test question are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.Why was Jennifer watched in an online exam?
| A．To correct her typing mistakes. |
| B．To find her secrets in the room. |
| C．To prevent her from slowing down. |
| D．To keep her from dishonest behaviors. |
The underlined expression cutting edge in Paragraph 3 is closest in meaning to______.
| A．advanced technique | B．sharpening tool |
| C．effective rule | D．dividing line |
For Internet universities, exams and diplomas will be valid if _____.
| A．they can attract potential students | B．they can defeat academic cheating |
| C．they offer students online help | D．they offer many online courses |
Some programs can find out possible cheaters by _____.
| A．checking the question answering speed |
| B．producing a large number of question |
| C．scanning the Internet test question |
| D．giving difficult test question |
Which of the following is the best title of this passage?
| A．The Advantages of Online Exams |
| B．The High-tech Methods in Online Courses |
| C．The Fight against Cheating in Online Education |
| D．The War against the Booming of Online Education |
One might expect that the ever-growing demands of the tourist trade would bring nothing but good for the countries that receive the holiday-makers. Indeed, a rosy picture is painted for the long-term future of the holiday industry. Every month sees the building of a new hotel somewhere, and every month another rock-bound Pacific island is advertised as the 'last paradise(天堂) on earth'.
However, the scale and speed of this growth seem set to destroy the very things tourists want to enjoy. In those countries where there was a rush to make quick money out of sea-side holidays, over-crowded beaches and the concrete jungles of endless hotels have begun to lose their appeal.
Those countries with little experience of tourism can suffer most. In recent years, Nepal set out to attract foreign visitors to fund developments in health and education. Its forests, full of wildlife and rare flowers, were offered to tourists as one more untouched paradise. In fact, the nature all too soon felt the effects of thousands of holiday-makers traveling through the forest land. Ancient tacks became major routes for the walkers, with the consequent exploitation of precious trees and plants.
Not only can the environment of a country suffer from the sudden growth of tourism. The people as well rapidly feel its effects. Farmland makes way for hotels, roads and airports; the old way of life goes. The one-time farmer is now the servant of some multi-national organization; he is no longer his own master. Once it was his back that bore the pain; now it is his smile that is exploited. No doubt he wonders whether he wasn't happier in his village working his own land.
Thankfully, the tourist industry is waking up to the responsibilities it has towards those countries that receive its customers. The protection of wildlife and the creation of national parks go hand in hand with tourist development and in fact obtain financial support from tourist companies. At the same time, tourists are being encouraged to respect not only the countryside they visit but also its people.
The way tourism is handled in the next ten years will decide its fate and that of the countries we all want to visit. Their needs and problems are more important than those of the tourist companies. Increased understanding in planning world-wide tourism can preserve the market for these companies. If not, in a few years’ time the very things that attract tourists now may well have been destroyed.What does the author indicate in the last sentence of Paragraph 1?
| A．The Pacific Island is a paradise. | B．The Pacific Island is worth visiting. |
| C．The advertisement is not convincing. | D．The advertisement is not impressive |
The example of Nepal is used to suggest _________.
| A．its natural resources are untouched |
| B．its forests are exploited for farmland |
| C．it develops well in health and education |
| D．it suffers from the heavy flow of tourists. |
What can we learn about the farmers from Paragraph 4?
| A．They are happy to work their own lands. |
| B．They have to please the tourists for a living. |
| C．They have to struggle for their independence. |
| D．They are proud of working in multi-national organizations. |
Which of the following determines the future of tourism?
| A．The number of tourists | B．The improvement of services. |
| C．The promotion of new products. | D．The management of tourism |
The author’s attitude towards the development of the tourist industry is __________.
| A．optimistic | B．doubtful | C．objective | D．negative |
We’ve considered several ways of paying to cut in line: hiring line standers, buying tickets from scalpers (票贩子), or purchasing line-cutting privileges directly from, say, an airline or an amusement park. Each of these deals replaces the morals of the queue (waiting your turn) with the morals of the market (paying a price for faster service).
Markets and queues—paying and waiting—are two different ways of allocating things, and each is appropriate to different activities. The morals of the queue, “First come, first served, have an egalitarian (平等主义的) appeal. They tell us to ignore privilege, power, and deep pockets.
The principle seems right on playgrounds and at bus stops. But the morals of the queue do not govern all occasions. If I put my house up for sale, I have no duty to accept the first offer that comes along, simply because it’s the first. Selling my house and waiting for a bus are different activities, properly governed by different standards.
Sometimes standards change, and it is unclear which principle should apply. Think of the recorded message you hear, played over and over, as you wait on hold when calling your bank: “Your call will be answered in the order in which it was received.” This is essential for the morals of the queue. It’s as if the company is trying to ease our impatience with fairness.
But don’t take the recorded message too seriously. Today, some people’s calls are answered faster than others. Call center technology enables companies to “score” incoming calls and to give faster service to those that come from rich places. You might call this telephonic queue jumping.
Of course, markets and queues are not the only ways of allocating things. Some goods we distribute by merit, others by need, still others by chance. However, the tendency of markets to replace queues, and other non-market ways of allocating goods is so common in modern life that we scarcely notice it anymore. It is striking that most of the paid queue-jumping schemes we’ve considered—at airports and amusement parks, in call centers, doctors’ offices, and national parks—are recent developments, scarcely imaginable three decades ago. The disappearance of the queues in these places may seem an unusual concern, but these are not the only places that markets have entered.According to the author, which of the following seems governed by the principle “First come, first served”?
| A．Taking buses. | B．Buying houses. |
| C．Flying with an airline. | D．Visiting amusement parks. |
The example of the recorded message in Paragraphs 4 and 5 illustrates ______.
| A．the necessity of patience in queuing |
| B．the advantage of modern technology |
| C．the uncertainty of allocation principle |
| D．the fairness of telephonic services |
The passage is meant to ______.
| A．justify paying for faster services |
| B．discuss the morals of allocating things |
| C．analyze the reason for standing in line |
| D．criticize the behavior of queue jumping |
Jimmy is an automotive mechanic, but he lost his job a few months ago. He has a good heart, but always feared applying for a new job.
One day, he gathered up all his strength and decided to attend a job interview. His appointment was at 10 am and it was already 8:30. While waiting for a bus to the office where he was supposed to be interviewed, he saw an elderly man wildly kicking the tyre of his car. Obviously there was something wrong with the car. Jimmy immediately went up to lend him a hand. When Jimmy finished working on the car, the old man asked him how much he should pay for the service. Jimmy said there was no need to pay him; he just helped someone in need, and he had to rush for an interview. Then the old man said, “Well, I could take you to the office for your interview. It’s the least I could do. Please, I insist.” Jimmy agreed.
Upon arrival, Jimmy found a long line of applicants waiting to be interviewed. Jimmy still had some grease on him after the car repair, but he did not have much time to wash it off or have a change of shirt. One by one, the applicants left the interviewer’s office with disappointed look on their faces. Finally his name was called. The interviewer was sitting on a large chair facing the office window. Rocking the chair back and forth, he asked, “Do you really need to be interviewed?” Jimmy’s heart sank. “With the way I look now, how could I possibly pass this interview?” he thought to himself.
Then the interviewer turned the chair and to Jimmy’s surprise, it was the old man he helped earlier in the morning. It turned out he was the General Manager of the company.
“Sorry I had to keep you waiting, but I was pretty sure I made the right decision to have you as part of our workforce before you even stepped into the office. I just know you’d be a trustworthy worker. Congratulations!” Jimmy sat down and they shared a cup of well-deserved coffee as he landed himself a new job. Why did Jimmy apply for a new job?
| A．He was out of work | B．He was bored with his job |
| C．He wanted a higher position | D．He hoped to find a better boss |
What did Jimmy see on the way to the interview?
| A．A friend’s car had a flat tyre | B．a wild man was pushing a car |
| C．a terrible accident happened | D．an old man’s car broke down |
Why did the old man offer Jimmy a ride?
| A．He was also to be interviewed | B．He needed a traveling companion |
| C．He always helped people in need | D．He was thankful to Jimmy |
How did Jimmy feel on hearing the interviewer’s question?
| A．He was sorry for the other applicants |
| B．There was no hope for him to get the job |
| C．He regretted helping the old man |
| D．The interviewer was very rude |
What can we learn from Jimmy’s experience？
| A．Where there is a will, there’s a way |
| B．A friend in need is a friend indeed |
| C．Good is rewarded with good. |
| D．Two heads are better than one |
There is a common belief among parents that schools are no longer interested in spelling. No school I have taught in has ever considered spelling unimportant as a basic skill. There are, however, quite different ideas about how to teach it, or how much priority (优先) it must be given over general language development and writing ability. The problem is, how to encourage a child to express himself freely in writing without holding him back with spelling.
If spelling becomes the only point of his teacher’s interest, clearly a bright child will be likely to “play safe”. He will write only words within his spelling range (范围). That’s why teachers often encourage the early use of dictionaries and pay attention to content rather than technical ability.
I was once shocked to read on the bottom of a sensitive piece of writing about a personal experience:“This work is terrible! There are far too many spelling mistakes.” It may have been a sharp criticism(批评) of the pupils technical abilities in writing, but it was also a sad thing for the teacher who had omitted (略过) to read the composition, which contained some beautiful expressions of the child’s deep feelings. The teacher was not wrong to draw attention to the mistakes, but if his priority had centered on the child's ideas, an expression of his disappointment with the presentation would have given the pupil more hope to seek improvement.The expression “play safe” probably means ____.
| A．to write carefully | B．to do as teachers say |
| C．to use dictionaries frequently | D．to avoid using words one is not sure of |
Teachers encourage the use of dictionaries so that____.
| A．students will be able to express their ideas more freely |
| B．teachers will have less trouble in correcting mistakes |
| C．students will have more trust in writing |
| D．students will learn to spell words correctly |
The writer seems to think that the teacher’s judgement on that sensitive piece of writing is____.
| A．reasonable | B．unfair | C．foolish | D．careless |
The major point discussed in the passage is _______.
| A．the importance of developing writing skills |
| B．the importance of spelling |
| C．the correct way of marking composition |
| D．the relationship between spelling and the content of a composition |

In a world with limited land, water and other natural resources, the harm from the traditional business model is on the rise. Actually, the past decade has seen more and more forests disappearing and the globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable（可持续的）ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the earth healthy while using its supply of natural resources.
Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for low-carbon energy will become three times bigger over the next decade. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil, which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%.
Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emissions（排放）and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development. Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from traditional model to a sustainable one.
The major challenge of this century is to find ways to meet the needs of growing population within the limits of this single planet. That is no small task, but it offers abundant new chances for sustainable product industries.The traditional business model is harmful because of all the following EXCEPT that _________.
| A．it consumes natural resources |
| B．it makes the world warmer |
| C．it brings severe damage to forests |
| D．it makes growth hard to continue |
What can we infer from Paragraph 2?
| A．China lacks wind and solar energy. |
| B．China is the leader of the low-carbon market. |
| C．Palm oil is made at the cost of valuable forests. |
| D．High-speed trains are a low-carbon development. |
To fully develop the low-carbon markets, governments can ________.
| A．cut public expenses | B．encourage energy conservation |

“The first and best of victories for a man is to conquer himself; to be conquered by himself is, of all things, the most shameful,” says Plato. Self-control is at the root of all the advantages. Let a man give in to his impulses (冲动) and feelings, and from that moment he gives up his moral freedom.
A single angry word has lost many friends. When Socrates found in himself any temper or anger, he would check it by speaking low in order to control himself. If you are conscious of being angry, keep your mouth shut so that you can hold back rising anger. Many a person has dropped dead in great anger. Fits of anger bring fits of disease. “Whoever the gods would destroy, they first make them mad.” “Keep cool,” says Webster, “anger is not argument.” “Be calm in arguing,” says George Herbert, “for fierceness makes error a fault.”
To be angry with a weak man is to prove that you are not strong yourself. “Anger,” says Pythagoras, “begins with foolishness and ends with regret.” You must measure the strength of a man by the power of the feelings he conquers, not by the power of those which conquer him.
Self-control is man’s last and greatest victory.
If a man lacks self-control he seems to lack everything. Without it he can have no patience, no power to govern himself; he can have no self-confidence, for he will always be controlled by his strongest feeling.

NASA has opened the door to the next generation of space discovery by announcing great plans for a base for humans to live on the surface of the moon forever.
The project to build a base on the moon will begin soon after 2020, with astronauts living there within four years.
The project comes after several excellent scientists and environmentalists asked humans to look beyond Earth to ensure the survival of the species (物种).
Eventually, the moon will be a base for humans to explore the solar system and one day land on Mars.
NASA began planning for the first moon landing since 1972 when George Bush, the US president, announced his new plan for space exploration four years ago.
NASA has already talked about the design of the Orion spacecraft that will replace the old space shuttle fleet in 2010.
The plan for the moon base, however, is the first detailed explanation of how NASA intends to prepare for the first manned exploration of deep space and a possible Mars mission within 30 years.
Scientists also believe that the south pole on the moon contain rich natural gases such as the rare helium-3 that could be used as fuel for the generation of nuclear power. Besides, teams of astronauts living there for six months at a time would mine for hydrogen and oxygen to make water and possibly rocket fuel.When was the plan to explore space first announced according to the passage?

When someone has deeply hurt you, it can be extremely difficult to let go of your grudge. But forgiveness is possible and it can be surprisingly helpful to your physical and mental health. Indeed, research has shown that people who forgive report more energy, better appetite （胃口） and better sleep patterns. "People who forgive show less anger and more hopefulness," says Dr. Frederic Luskin, who wrote the book Forgive for Good. “So it can help save on the wear and tear, and allow people to feel more energetic."
So when someone has hurt you, calm yourself first. Take a couple of breaths and think of something that gives you pleasure: a beautiful scene in nature, someone you love. Don’t wait for an apology. "Many times the person who hurt you may never think of apologizing," says Dr. Luskin. "They may have wanted to hurt you or they just don't see things the same way. So if you wait for people to apologize, you could be waiting a very long time.” Keep in mind that forgiveness does not necessarily mean accepting the action of the person who upset you. Mentally going over your hurt gives power to the person who brought you pain. Instead, learn to look for the love, beauty and kindness around you. Finally, try to see things from the other person' s perspective. You may realize that he or she was acting out of ignorance(无知), fear even love. To gain perspective, you may want to write a letter to yourself from that person’s point of view.The word “grudge” in the first paragraph most probably means _________.
| A．understanding | B．forgiveness | C．anger | D．pity |
What’s the main idea of the first paragraph?
| A．Forgiveness keeps yourself from being hurt. | B．Forgiveness helps stay mentally healthy. |
| C．Forgiving others does good to your health. | D．Forgiving yourself is the biggest challenge. |
According to the writer, what is the best way to calm down after being hurt?
| A．Try to figure out why you get hurt. |
| B．Writer a letter to person who hurt you. |
| C．Persuade yourself to accept what others have done to you. |
| D．Think about pleasant things and forget about the hurt. |
Dr. Luskin advises us not to wait for an apology after being hurt because ______.
| A．people seldom want to apologize | B．we’d feel worse accepting others' apology |
| C．we are not patient enough | D．people don’t mean it when they apologize |
