While all my classmates seen to be crazy about a one-way ticket to Mars(火星), I’d rather say Mars is totally unsuitable for human existence. People won’t have enough food supplies there, and the terrible environment would make it impossible for them to live a long life. Besides, the journey won’t be safe. Can anybody explain to me just why people would go to Mars, never to return?

Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory…For scientists there is another reason. Their observations and research will probably lead to great scientific achievements.

There are already too many people on the Earth. I think that sometime before the end of the century, there will be a human colony(殖民地)on Mars. It will happen when people finally realize that tow-way trips to the red planet Mars are unnecessary. Most of the danger of space Flight is in the launches(发射) and landings. Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement on another world.
Enough supplies can be sent on ahead. And every two years more supplies and more people will needs, and Mars is far more pleasant than the other planets in the outer space.

I arrived at my mother’s home for our Monday family dinner. The smells of food flew over from the kitchen. Mother was pulling out quilt(被子)after quilt from the boxes, proudly showing me their beauties. She was preparing for a quilt show at the Elmhurst Church. When we began to fold and put them back into the boxes, I noticed something at the bottom of one box. I pulled it out. “What is this?” I asked.
“Oh?” Mom said, “That’s Mama’s quilt.”
I spread the quilt. It looked at if a group of school children had pieced it together; irregular designs, childish pictures, a crooked line on the right.
“Grandmother made this?” I said, surprised. My grandmother was a master at making quilts. This certainly didn’t look like any of the quilts she had made.
“Yes, right before she died. I brought it home with me last year and made some changes,” she said. “I’m still working on it. See, this is what I’ve done so far.”
I looked at it more closely. She had made straight a crooked line. At the center of the quilt, she had stitched(缝) a piece of cloth with these words: “My mother made many quilts. She didn’t get all lines straight. But I think this is beautiful. I want to see it finished. Her last quilt.”
“Ooh, this is so nice, Mom,” I said. It occurred to me that by completing my grandmother’s quilt, my mother was honoring her own mother. I realized, too, that I held in my hands a family treasure. It started with the loving hands of one woman, and continued with the loving hands of another.

Almost every day we come across situations in which we have to make decisions one way or another. Choice, we are given to believe, is a right. But for a good many people in the world. In rich and poor countries, choice is a luxury, something wonderful but hard to get, not a right. And for those who think they are exercising their right to make choices, the whole system is merely an illusion, a false idea created by companies and advertiser, hoping to sell their products.
The endless choice gives birth to anxiety in people's lives. Buying something as basic as a coffee pot is not exactly simple. Easy access to a wide range of everyday goods leads to a sense of powerlessness in many people, ending in the shopper giving up and walking away, or just buying an unsuitable item(商品) that is not really wanted. Recent studies in England have shown that many electrical goods bought in almost every family are not really needed. More difficult decision-making is then either avoided or trusted into the hands of the professionals, lifestyle instructors, or advisors.
It is not just the availability of the goods that is the problem, but the speed with which new types of products come on the market. Advances in design and production help quicken the process Products also need to have a short lifespan so that the public can be persuaded to replace them within a short time. The typical example is computers, which are almost out-of-date once they are bought. This indeed makes selection a problem. Gone are the days when one could just walk with case into a shop and buy one thing; no choice, no anxiety.

Seeing a volcano erupt (喷发) is a wonderful experience, and you can really feel the beat by climbing to the summit(山顶) of Pacaya for a close-up view. There are guided tours every day up this highly active volcano from Antigua. Giving travelers a chance to see Mother Nature at her most powerful.
Pacaya is an easy drive from Antigua, a beautiful city with many colorful houses along its old streets that are turned into art-works during its Holy Week festival. No matter when you come to Antigua, you won't miss the Pacaya-tour companies.
But climbing Pacaya is no easy job: it is 2560 metres high, and reaching the summit takes two to three hours of seemingly one-step-forward and two-step-back movements. As you climb, you hear the dull sounds of eruptions high above. Steaming. Hot remains from recent eruptions begin to line the path as you near the active summit; the McKenney Cone(火山锥). Just as though you were going to walk over to the edge of the cone, the road turns to the left and up to the relative safety of the old, inactive summit.
Many tours are timed so that you arrive at the cone of the volcano is plenty of time for sunset and the full contrast between the erupting red lava(熔岩) and the darkening sky. On a good day the view from the summit is extremely exciting. The active mouth boils, sending red lava over its sides, and once in a while shoots hot streams up to 100 metres into the air. There is a strong bad smell in the air even if you take care to be upwind of the cone. As evening turns deeper into the night. the burning lava quietly falls down tae side of the volcano. For you, too, it is time to get down .

Being able to multitask-doing several things at the same time-is considered a welcome skill by most people. But if we consider the situation of the young people aged from eight to eighteen, we should think again.
What we often see nowadays is that young people juggle an ever larger number of electronic devices(电子产品)as they study. While working, they also surf on the Internet, send out emails, answer the telephone and listen to music on their iPods. In a sense, they are spending a significant amount of time in fruitless efforts as they multitask.
Multitasking is even changing the relationship between family members. As young people around them. They can no longer greet family members when they enter the house, nor can they cat at the family table.
Multitasking also affects young people's performance at university and in the workplace. When asked about their opinion of the effect of modern gadgets(器具)on their performance of tasks, many young people gave a positive response(反应). However, the response from the worlds of education and business was not quite as positive. Educators feel that multitasking by children has a serious effect on later development of study skills. They believe that many college students now need help to improve their study skills. Similarly, employers feel that young people entering the job market need to be taught all over again, as modern gadgets have made it unnecessary for them to learn special skills to do their work.

A simple piece of clothesline hangs between some environmentally friendly Americans and their neighbors.
On one side stand those who see clothes dryers(干衣机) as a waste of energy and a major polluter of the environment. As a result, they are turning to clotheslines as part of the “what-I –can do environmentalism(环境保护主义).”
On the other side are people who are against drying clothes outside, arguing that clotheslines are unpleasant to look at. They have persuaded Homeowners Associations (HOAs) access the U.S. to ban outdoor clotheslines, because clothesline drying also tends to lower home value in the neighborhood. This had led to a Right-to-Dry Movement that is calling for laws to be passed to protect people’s right to use clotheslines.
So far, only three states have laws to protect clothesline. Right-to-Dry supporters argue that there should be move.
Matt Reck, 37, is the kind of eco-conscious(有生态意识的) person who feeds his trees with bathwater and reuses water drops from his air conditioners to water plants. His family also uses a clothesline. But on July 9, 2007, the HOA in Wake Forest, North Carolina, told him that a dissatisfied neighlzir had telephoned them about him clothesline. The Recks paid no attention to the warming and still dried their clothes on a line in the yard. “Many people say they are environmentally friendly but they don’t take matters in their own hands,” says Reck. The local HOA has decided not to take any action, unless more neighbors come to them.
North Carolina lawmakers are saying that banning clotheslines is not the right thing to do. But HOAs and housing businesses believe that clothesline drying reminds people of poor neighborhoods. They worry that if buyers think their future neighbors can’t even afford dryers, housing prices will fall.
Environmentalists say such worries are not necessary, and in view of global warming, that idea needs to change. As they say, “The clothesline is beautiful”. Hanging clothes outside should be encouraged. We all have to do at least something to slow down the process of global warming.”One of the reasons why supporters of clothes dryers are trying to ban clothesline drying is that ____.
| A．clothes dryers are more efficient | B．clothesline drying reduces home value |
| C．clothes dryers are energy-saving | D．clothesline drying is not allowed in most U.S. states |
Which of the following best describes Matt Reck?
| A．He is a kind-hearted man. | B．He is an impolite man. |
| C．He is and experienced gardener. | D．He is a man of social responsibility. |
Who are in favor of clothesline drying?
| A．housing businesses. | B．Environmentalists. |
| C．Homeowners Associations. | D．Reck’s dissatisfied neighbors. |
What is mainly discussed in the text?
| A．Clothesline drying: a way to save energy and money. |
| B．Clothesline drying: a lost art rediscovered. |
| C．Opposite opinions on clothesline drying. |
| D．Different varieties of clotheslines. |
For a while, my neighborhood was taken ever by an army of joggers(慢跑者). They were there all the time: early morning, noon, and evening. There were little old ladies in gray sweats, young couples in Adidas shoes, middle-aged men with red faces. "Come on!" My friend Alex encouraged me to join him as he jogged by my house every evening. "You'll feel great."
Well, I had nothing against feeling great and if Alex could jog every day, anyone could. So I took up jogging seriously and gave it a good two months of my life, and not a day more. Based on my experience, jogging is the most overvalued form of exercise around, and judging from the number of the people who left our neighborhood jogging army. I'm not alone in my opinion.
First of all, jogging is very hard on the body. Your legs and feet a real pounding（追击）ruining down a road for two or three miles. I developed foot, leg, and back problems. Then I read about a nationally famous jogger who died of a heart attack while jogging, and I had something else to worry about. Jogging doesn't kill hundreds of people, but if you have any physical weaknesses, jogging will surely bring them out, as they did with me.
Secondly, I got no enjoyment out of jogging. Putting one foot in front of the other for forty-five minutes isn't my idea of fun. Jogging is also a lonely pastime. Some joggers say, "I love being out there with just my thoughts" Well, my thoughts began to bore me, and most of them were on how much my legs hurt.
And how could I enjoy something that brought me pain? And that wasn't just the first week: it was practically every day for two months. I never got past the pain level, and pain isn't fun. What a cruel way to do it! So many other exercises, including walking, lead to almost the same results painlessly, so why jog?
I don't jog any more, and I don't think I ever will. I'm walking two miles three times a week at a fast pace, and that feels good. I bicycle to work when the weather is good. I'm getting exercise, and I'm enjoying it at the same time. I could never say the same for jogging, and I've found a lot of better ways to stay in shape.

A Brown University sleep researcher has some advice for people who run high schools: Don't start classes so early in the morning. It may not be that the students who nod off at their desks are lazy. And it may not be that their parents have failed to enforce (确保) bedtime. Instead, it may be that biologically these sleepyhead students aren't used to the early hour.
"Maybe these kids are being asked to rise at the wrong time for their bodies," says Mary Carskadon, a professor looking at problem of adolescent (青春期的) sleep at Brown's School of Medicine.
Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more basic level. she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns.
Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought.
Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at nigh and sleep later in the morning. But it's not just a matter of choice -their bodies are going through a change of sleep patters.
All of this makes the transfer from middle school to high school-which may start one hour earlier in the morning ---- all the more difficult , Carskadon says. With their increased need for sleep and their biological clocks set on the "sleep late, rise late" pattern, adolescent are up against difficulties when it conics to trying to be up by 5 or 6 a.m. for a 7:30 a.m. first hell. A short sleep on a desktop may be their body's way of saying. "I need a timeout."

Hi, everyone. What would you miss most and least if you were stuck on a desert island? For me, it would be the changing seasons in New England. I guess this will sound stupid but I’d probably miss the rain, too. I wouldn’t miss getting up at six every day to go to work, though! What about you? |

Good question. Steve, I think I’d miss different types of bread, and shopping at the supermarket. I’d miss the food most. What would I miss least? My mobile phone---I’d like to be completely quiet --- at least for a little while |
| Post 3 Paola Italy |
I would miss the company of people because I know I’d like to have someone to share experiences with. I’d go mad on my own. And I sure wouldn’t miss junk mail(垃圾邮件) --- I hate coming home every evening and a pile of junk mail in my post box. |
| Post 4 Miko Japan |
Hi, I would miss Manga cartoon, the internet and Japanese food, like sushi. I’d also miss TV shows and shopping for clothes… In fact, I’d miss everything. |
| Post 5 Roger UK |
I would miss my daily newspaper and listening to the news on TV and radio. I’d feel very cut off if I didn’t know what was happening in the world. What I’d miss least would be traffic jams in the city, particularly my journey to work. |

Adrian's "Amazing Race" started early when his parents realized that he, as a baby, couldn't hear a thing, not even loud noises. In a special school for the hearing-impaired (听觉受损的)，he learned sign language and got to mix with other disabled children. However, the sight of all the disabled children communicating with one another upset his mother. She wanted him to lead a normal life. So after speaking to an advisor, she sent him to private classes where he learned to read lips and pronounce words.
Later on, Adrian's parents decided to send him to a regular school. But the headmaster tried to prevent them from doing so, saying regular school couldn't take care of a special needs students. His parents were determined to take the risk and push him hard to go through his work everyday because they wanted to prove that, given the opportunity, he could do anything. Adrian made the grade and got accepted. It was a big challenge. The pace （节奏）was faster so he had to sit at the front of the class and really pay attention to the teacher, which wasn't always easy. But he stuck to it and did a lot of extra work after school.
The efforts made by Adrian and his parents paid off. Adrian graduated with good grades and got into a top high school. He also achieved a lot in life outside school. He developed a love for the outdoors and went to Nepal to climb mountains. He even entered the World Yacht Race 05/06--- being the first hearing-impaired Asian to do so.
But none of these achievements would have been possible without one of the most important lessons from his mother." "If you believe in yourself and work hard, you can achieve great results." She often said.

It had been some time since Jack had seen the old man. College, carrier, and life itself got in the way. In fact, Jack moved clear across the country in pursuit of the dreams. There, in the rush of his busy life, Jack had little time to think about the past and often no time to spend with his wife and son. He was working on his future, and nothing could stop him.
Over the phone, his mother told him, "Mr. Belser died last night. The funeral is Wednesday." Memories fleshed through his mind like an old newsreel as he sat quietly remembering his childhood days.
"Jack, did you hear me?"
"Oh, sorry, Mom. Yes, I heard you. it's been so long since I thought of him. I'm sorry, but I honestly thought he died years ago," Jack said.
"Well, he didn't forget you. Every time I saw him he'd ask how you were doing. He'd reminisce (回忆) about the many days you spent over 'his side of the fence' as he put it, " Mom told him.
"I loved that old house he lived in," Jack said.
"You know, Jack, after your father died, Mr. Belser stepped in to make sure you had a man's influence in your life," she said.
"He's the one who taught me carpentry. I wouldn't be in this business if it weren't for him. He spent a lot of time teaching me things he thought were important. Mom, I'll be there for the funeral." Jack said.
Busy as he was, he kept his word. Jack caught the next flight to his hometown. Mr. Belser's funeral was small and uneventful. He had no children of his own, and most of his relatives had passed away.
The night before he had to return home, Jack and his Mom stopped by to see the old house next door one more time, which was exactly as he remembered. Every step held memories. Every picture, every piece of furniture … Jack stopped suddenly.
"What's wrong, Jack?" his Mom asked.
"The box is gone," he said.
"What box?" Mom asked.
"There was a small gold box that he kept locked on top of his desk. I must have asked him a thousand times what was inside. All he'd ever tell me was 'the thing I value most'," Jack said.
It was gone. Everything about the house was exactly how Jack remembered it, except for the box. He figured someone from the Belser family had taken it.
"Now I'll never know what was so valuable to him," Jack said sadly.
Returning to his office the next day, he found a package on his desk. The return address caught his attention.
"Mr. Harold Belser" it read.
Jack tore open the package. There inside was the gold box and an envelope. Jack's hands shook as he read the note inside,
"Upon my death, please forward this box and its contents to Jack Bernett. It's the thing I valued most in my life." A small key was taped to the letter. His heart racing, and tears filling his eyes. Jack carefully unlocked the box. There inside he found a beautiful gold pocket watch. Running his fingers slowly over the fine cover, he opened it.
Inside he found these words carved: "Jack. Thanks for your time! Harold Belser."
"Oh. My God! This is the thing he valued most …"
Jack held the watch for a few minutes, then called his assistant and cleared his appointments for the next two days. "Why?" his assistant asked.
"I need some time to spend with my son," he said.

We experience different forms of the Sun’s energy every day. We can see its light and feel its warmth. The Sun is the major source of evaporation (蒸发) of water from the oceans and lakes. Sunlight also provides the energy used by green plants to make their own food. These green plants then provide food for all organisms (生物) on the Earth.
Much of the energy that comes from the Sun never reaches the Earth’s surface. It is either reflected or absorbed by the gases in the upper atmosphere. Of the energy that reaches the lower atmosphere, 30% is reflected by clouds or the Earth’s surface. The remaining 70% warms the surface of the planet, causes water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, approximately 0.023%, is actually used by green plants to produce food.
Many gases found in the atmosphere actually reflect heat energy escaping from the Earth’s surface back to the Earth. These gases act like the glass of a greenhouse in that they allow energy from the Sun to enter but prevent energy from leaving. They are therefore called greenhouse gases.
When sunlight strikes an object, some of the energy is absorbed and some is reflected. The amount reflected depends on the surface. For example, you’ve probably noticed how bright snow is when sunlight falls on it. Snow reflects most of the energy from the Sun, so it contributes to the low temperatures of winter. Dark-coloured surfaces, such as dark soil or forest, absorb more energy and help warm the surrounding air.According to the passage, the root cause for weather changes on the Earth is ______.
| A．the atmosphere surrounding the Earth | B．water from oceans and lakes |
| C．energy from the Sun | D．greenhouse gases in the sky |
Only a small part of the Sun’s energy reaches the Earth’s surface because most of it _______________.
| A．absorbed by the clouds in the lower atmosphere |
| B．reflected by the gases in the upper atmosphere |
| C．lost in the upper and lower atmosphere |
| D．used to evaporate water from the oceans and lakes |
We learn from the passage that _______________.
| A．all living things on the Earth depend on the Sun for their food |
| B．a forest looks dark in winter because it absorbs solar energy |
| C．only 0.023% of the energy from the Sun is made use of on the Earth |
| D．greenhouse gases allow heat energy to escape from the Earth’s surface |
