It is interesting how NASA(美国航天航空局) chose their astronauts for landing them on the moon. They chose men 36 the ages of twenty and thirty-five. There were about fifty of them. Some were 37 air pilots, and 38 were scientists with two or three degrees. NASA telephoned each man they were going to choose, told him the plans and the 39 they might get into. They then asked him if he was willing to be trained as an astronaut, “How could any man 40 such an exciting job?” One of them said, “Dangerous? Of course. It’s dangerous 41 most exciting.”
The health and physical condition of the people was, 42 , very necessary. Only those in very good health and physical condition were 43 .
While being trained to be astronauts, they went through many 44 . They studied the star and the moon, and they also studied geology, the science of rocks. This was necessary 45 astronauts would have to look for rocks on the moon. They would try to find rocks which might help to tell the 46 of the moon. They were all 47 to fly in helicopters. There helicopters landed straight down to give them some 48 of the way the spaceship would actually land on the 49 . They were also taught the known facts about the 50 in space. They learnt about all the scientists and engineers who 51 spaceships. They visited the 52 where spaceships were repaired. They learnt how every 53 of a spaceship and its instruments work. They also learnt every detail of ground-control 54 .
In a word, to be chosen as astronaut, one must be in good 55 , well-informed in science and good at piloting.

Secondhand smoke clearly kills people and the only way to control it is to ban smoking in all workplaces, US Surgeon-General Dr Richard Carmona said.
In 1964Surgeon General’s report first laid out the 21 of smoking. Years later, in another report Dr Richard Carmona 22 the effects of secondhand smoke and said no one should be forced to inhale it.
“Secondhand smoke causes early death and disease in children and in 23 who do not smoke,” the report reads. “Children 24 to secondhand smoke are at an increased risk for sudden infant death syndrome（综合症）, acute respiratory（呼吸道） infections, and ear problems,” it adds.
Smoking by 25 causes respiratory symptoms and slows lung growth in their children. A 2005 report from the US Centers for Disease Control and Prevention found that 430 26 died every year in the United States from sudden infant death syndrome-all 27 by secondhand smoke.
States, 28 and other local authorities have battled over instituting（制定）smoking bans. Some 29 , especially bars and restaurants, have said they will lose business if smoking is completely banned. But the report said it is impossible to protect non-smokers even with designated smoking areas, and at least one report from California, which has strict bans, has shown no 30 on businesses.

23．A．gentlemen B．mothers C．youngstersD．adultsAre you a man or a mouse? When people ask this question they want to know whether you think you are a 36 person or a coward (懦夫). But you will never really know the answer to this question 37 you are tested in real life. Some people think they are brave, but when they come face to face with real 38 , they act like cowards. Others think of themselves as cowards, but when they meet danger, they act like heroes.
Lenny had always thought of himself as a 39 person. He got worried before examinations. He worried about his job and health. All he wanted in life was to be safe and healthy. Then on January 15th, 2002, a plane crashed into the Potomac River in Washington. Lenny happened to see a woman in the ice-cold water. He did not feel afraid. He 40 very calm and did a very dangerous thing. He jumped into the Potomac, 41 to the woman, and kept her head 42 the water. Seventy-eight people died that day. Thanks to Lenny, it was not 43 .
When you are in a very dangerous situation and feel afraid, the body automatically(自动地) produces a chemical called adrenalin in the blood. With adrenalin in the blood system, you actually feel stronger and stronger and are 44 to fight or run away. However, when you are terrified greatly, the body can produce too much adrenalin. 45 this happens, the muscles become very hard. You are then paralyzed (麻木) with fear. This is why when we are extremely frightened, we sometimes say we are “petrified”. This word 46 a Greek word “petros”, which means “stone”. We are 47 frightened that we become stonelike.

We have known for a long time that flowers of different plants open and close at different times of day. This is so 1 that there seems to be no need to ask the reason for it. Yet no one 2 understands why flowers open and close like this at particular times. The process is not as 3 as we might think, as recent experiments have shown. In one study, flowers were kept in constant 4 . We might expect that the flowers, without any information about the time of day, did not open as they 5 do. As a matter of fact, they 6 to open at their usual time. This suggests that they have some mysterious(神秘的) way of k
nowing the 7 . Their sense of time does not 8 information from the outside world; it is, so to speak, inside them, a kind of “inner clock”.
This 9 may not seem to be very important. However, it was later found that not just plants but also 10 , including man, have this “inner clock” which 11 the working of their bodies and influences their activities. Men, then, are also influenced by this mysterious 12 . Whether we wish it or not, it affects such things in our life as our need for sleep, our need for food.
In the past, this did not really 13 because people lived in natural condition. In
the 14 world, things are different; now there are spacemen, airplane pilots and, in ordinary life, a lot of people who have to work at night. It would be very 15 , then, to know more about the “inner clock”. Such things as flowers might help us understand more about ourselves.

Sea turtles have been on Earth for millions of years, but they may soon die out. The main 1 to them is people who kill them for food, according to Dr. Wallace J. Nichols of the University of California.
But the latest news may 2 turtle hunting: Dr. Nichols has found that sea turtles 3 a lot of pollution from the ocean. This pollution is unhealthy for both turtles and humans. It can cause __4__ damage to their bodies and lead to death. Research shows that many people get sick and even die from eating sea turtle meat.
In the US, most people have never eaten turtle. This is because turtles are 5 by the United States law, which makes it 6 to harm or kill these amazing animals. “But many people in other countries still eat them,” explains Nichols. “Our first 7 was to save turtles; now we must save 8 too.”
Davis said he also wants to send out a bigger 9 that we should protect the oceans. “The health of the ocean, animals in the ocean, and our own health are all 10 . A clean ocean is really good for us too because of the food we eat from there.”

Countless people appear in your life---familiar or strange, close or distant. Sometimes people come into your life and you know right away that they were meant to be there to serve some sort of , to teach you a lesson, or to help you who you are or who you want to become. You never think about who these people may be (possibly your roommate, neighbor, co-worker, long lost friend, lover, or even a complete stranger), but when you lock eyes with them, you know at that very moment they will your life in some way.
And sometimes things happen to you that may seem horrible, painful and unfair at first, but with more you find that without overcoming those difficulties you would have realized your potential, strength, willpower, or heart.
Everything happens for a reason. Nothing happens or by means of good luck. Illness, injury, love, lost moments of true greatness and complete stupidity all occur to the limits of your soul. these small tests whatever they may be, life would be like a smoothly paved（铺设）, straight, flat road to . It would be safe and comfortable, but dull and . The people you meet who affect your life, and the success and downfalls you experience, help to create who you are and who you become.
Even the experiences can be learned from. In fact, they are probably the most poignant(伤心的) and important ones. If someone hurts you, you, or breaks your heart, forgive them, for they have helped you learn about trust and the importance of being cautious when you open your heart. If someone loves you, love them back , not only because they love you, but because , they are teaching you to love and how to open your and eyes to things.
Make every day count. every moment and take from those moments everything that you possibly can for you may never be able to experience it again. Talk to people that you have never talked to , and actually listen. Let yourself fall in love, break free, and set your sights high. Hold your head up because you have right to. Tell yourself you are a great individual and believe in yourself, for if you don’t believe in yourself, it will be hard for others to believe in you. You can make your life anything you wish. Create your own life and then go out and live it with absolutely no .
Most importantly, if you LOVE someone, tell him or her, for you never know what tomorrow may have in . And learn a lesson in life each day that you live.
That’s the story of life.

Almost everyone wants to get smarter. We struggle to improve our 36_ , intelligence and attention. We drink cup after cup of coffee to help us 37_ the day.
38 __, a new study published in Current Directions in Psychological Science warns that there are 39___ to how smart humans can get.
Each of our body parts develops in a certain way for a reason. 40 _, we are not 3 meters tall 41 _ most people’s hearts are not strong enough to send 42 _ up that high. Scientists say that our thinking ability works in the same way. A baby’s brain size is limited by a series of __43 , such as the size of the mother’s pelvis (骨盆). If our brains developed to be bigger, there could be more 44 during childbirth.
The study of Jews, who have an average IQ much _ 45_ than other Europeans, showed they were more _46_ to develop diseases of the _47_ system. This might be because of their increased brainpower.
If intelligence cannot be improved, can we at least get better at _ 48 _ ? Not really, say scientists. They studied _49_ like caffeine (咖啡因)that improve attention. They found the drugs only helped people with serious 50 _ problems. For those who did not have trouble paying attention, the drugs could have the 51 _ effect. Scientists say that this suggests there is a(n) 52 limit to how much people can or should concentrate.
Our memory is also a “double-edged sword”. People with extremely good memories could 53__ having a difficult life because they cannot _54 bad things that happen to them.
Thomas Hills, one of the authors of the paper, said that 55 all the problems in trying to get smarter, it’s unlikely that there will ever be a “super mind”.

Water and its importance to human life were the centre of the world’s attention last week. March 22 was World Water Day and 36 the theme “Water for Life”.
There are more than one billion people in the world who live without 37 drinking water. The United Nations 38 to cut this number in half by 2015.
Solving such a big problem seems like a(n) 39 challenge. But everyone, 40 teenagers, can do something to help. A teenage girl in the US has set an example to the 41 of her age around the world.
Rene Haggerty, 13, was awarded the 2004 Gloria Barron Prize for her work— 42 discarded(废弃的) batteries（电池）which pollute water.
In 2003, Haggerty went on a field trip to the Great Lakes Science Centre in Ohio. There she saw an exhibit about how 43 in old batteries harm the water of Lake Erie.
Haggerty learnt that 44 the batteries was an easy solution. “I think everybody can do it, because everyone 45 batteries, and it can make a big difference.” With these words, she began to 46 awareness in her area.
She 47 her county government and school board. She got permission to start a recycling programme in schools 48 the public library, hospital, and churches. With help from her family, friends and local waste-management 49 , she gathered containers, arranged transportation, and made a(n) 50 video.
Over the past two years, she collected four tons of batteries and drew the attention of officials, who were in charge of a battery recycling programme but had made 51 progress.
When asked 52 she feels like a hero, Haggerty is quite ____53 . “Not really. Well, maybe for the fish I saved!”
Every year the Gloria Barron Prize 54 young Americans aged 8 to 18 who have shown leadership and courage in 55 the public and the planet. Each year ten winners receive US $ 2,000 each, to help with their education costs or their public service work.

People do not analyse every problem they meet. Sometimes they try to remember a solution from the last time they had a 36 problem. They often accept the opinion or ideas of other people. Other times they begin to act without 37 ; they try to find a solution by trial and error. However, when all of these methods 38 , the person with a problem has to start analysing. There are six 39 in analysing a problem.
40 , the person must recognize that there is a problem. For example, Sam’s bicycle is broken, and he cannot ride it to class as he usually does. Sam must 41 that there is a problem with his bicycle.
Next the person must 42 the problem. Before Sam can repair his bicycle, he must know why it does not work. For example, he must 43 the parts that are wrong.
Now the person must look for 44 that will make the problem clearer and lead to 45 solutions. For example, suppose Sam 46 that his bike does not work because there is something wrong with the brakes. 47 , he can look in his bicycle repair book and read about brakes, talk to his friends at the bike shop, or look at his brakes carefully.
After 48 the problem, the person should have several suggestions for a possible solution. Take Sam as an example 49, his suggestions might be: tighten or loosen the brakes; buy new brakes and change the old ones.
In the end, one 50 seems to be the solution to the problem. Sometimes the 51 idea comes quite 52 because the thinker suddenly sees something in a 53 way. Sam, for example, suddenly sees there is a piece of chewing gum stuck to a brake. He immediately hits on the solution to his problem: he must 54 the brake.
Finally the solution is 55 . Sam does it and finds his bicycle works perfectly. In short he has solved the problem.

Though giant pandas may appear perfectly happy chewing bamboos, scientists recently discovered that they would rather have something sweeter. Scientists chose because the animals are herbivores (食草动物), which would mean that they would love sweets. However, the plant they choose, the bamboos, has a very sugar content and is therefore not considered sweet. Could this mean that pandas have their hobby for sweet things?
