Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses（球場）in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.
There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.
57. Which of the following is the author most probably in favor of?
A. Cycling around a lake                             B. Motor racing in the desert

A. It is popular in Portugal and Spain  
B. It causes water shortages around the world
C. It pollutes the earth with chemicals and wastes
D. It needs water and electricity to keep its courses green
59. The author uses power walking as an example mainly because______.
A. it is an outdoor sport                                  B. it improves our health
C. it uses fewer resources                                 D. it is recommended by experts
60. The author writes the passage to ______.

When I first got an email account ten years ago, I received communications only from family,friends,and colleagues.Now it seems that every time I check my e-mail ,I have an endless seriers of advertisement and otner correspondence that do not interest the at all.If we want e-mail to continue to be useful,we need special laws that make spamming(發(fā)送垃圾郵件) a crime.
If lawmakers do not do something soon to prohibit spam，the problem will certainly get much worse。Computer programs allow spammers to send hundreds of millions of e-mails almost instantly 。as more and more advertisers turn to spam to sell their products ，individual（個人的）e-mail boxes are often flooded with spam e-mails。Would people continue to use e-mail if they ahd to deal with an annoying amount of spam each time？
This problem is troubling for inviduals and companies as well. Many spam emails contain computer viruses that can shut down the entire network of a company.Companies rely on e-mail on on e-mail for their Comployees to communicate with each other.

For these reasons,I believe that lawmakers need to legislate (立法) against spam.Spammers should be fined,and perhaps sent to prison if they continue to disturb people.E-mail is a tool which helps people all over the world to communicate conveniently,but spam is destroying this conwenience.

Many a young person tells me he wants to be a writer. I always encourage such people, but I also explain that there’s a big difference between “being a writer” and writing. In most cases individuals are dreaming of wealth and fame, not the long hours alone at a typewriter. “You’ve got to want to write,” I say to them, not want to be a writer.”
The reality is that writing is a lonely, private and poor-paying affair. For every writer kissed by fortune there are thousands more whose longing is never rewarded. When I left a 20-year career in the US Coast Guard to become a freelance writer(自由撰稿者), I had no prospects at all. What I did have was a friend who found me a room in a New York apartment building. It didn’t even matter that it was cold and had no bathroom. I immediately bought used manual typewriter and felt like a genuine writer.
After a year or so, however, I still hadn’t got a break and began to doubt myself. It was so hard to sell a story that barely made enough to eat. But I knew I wanted to write. I had dreamed about it for years, I wasn’t going to be one of those people who die wondering. What if? I would keep putting my dream to the test-even though it meant living with uncertainly and fear of failure. This is the shadowland of hope, and any one with a dream must learn to live there.
1. The passage is meant to                 .
warn young people of the hardships that a successful writer has to experience
advise young people to give up their idea of becoming a professional writer
show young people it’s unrealistic for a writer to pursue wealth and fame
encourage young people to pursue a writing career
2. What can be concluded from the passage?
Genuine writers often find their work interesting and rewarding.
A writer’s success depends on luck rather than on effort.
Famous writers usually live in poverty and isolation.
The chances for a writer to become successful are small
3. Why did the author begin to doubt himself after the first year of his writing career?
He wasn’t able to produce a single look.
He hadn’t seen a change for the better
He wasn’t able to have a rest for a whole year.
He found his dream would never come true.
4. “I wasn’t going to be one of those people who die wondering. What if?” refers to “those               .”
who think too much of the dark side of life
who regret giving up their career halfway
who think a lot without making a decision
who are full of imagination even upon death
5. “Shadowland” in the last paragraph refers to              .
the wonderland one often dream about
the bright future that one is looking forward to
the state of uncertainty before one’s final goal is reached
a world that exists only in one’s imagination

I found out one time that doing a favor for someone could get you into a lot of trouble. I was in the eighth grade at the time, and we were having a final test. During the test, the girl sitting next to me whispered something, but I didn’t understand. So I leaned over her way and found out that she was trying to ask me if I had an extra pen. She showed me that hers was out of ink and would not write. I happened to have an extra one, so I took it out of my pocket and put it on her desk.
Later, after the test papers had been turned in, the teacher asked me to stay in the room when all the other students were dismissed. As soon as we were alone she began to talk to me about what it meant to grow up; she talked about how important it was to stand on your own two feet and be responsible (負責任) for your own acts. For a long time, she talked about honesty and emphasized the fact that when people do something dishonest, they are really cheating themselves. She made me promise that I would think seriously about all the things she had said, and then she told me I could leave. I walked out of the room wondering why she had chosen to talk to me about all those things.
Later on, I found out that she thought I had cheated on the test. When she saw me lean over to talk to the girl next to me, it looked as if I was copying answers from the girl’s test paper. I tried to explain about the pen, but all she could say was it seemed very very strange to her that I hadn’t talked of anything about the pen the day she talked to me right after the test. Even if I tried to explain that I was just doing the girl a favor by letting her use my pen, I am sure she continued to believe that I had cheated on the test.

Scientists have developed a water treatment system that they say is a powerful but simple way to save lives. Four grams of chemicals can treat ten liters of dirty water for a low cost, about ten cents.
Experts say infections from dirty water kill several thousand children in developing countries every day. The Procter and Gamble company has been developing the "PUR Purifier of Water" system since 1995. The company has been working with the United States Centers for Disease control and Prevention(C.D.C.).
C.D.C. researchers tested it in Guatemala, Pakistan and Kenya. Procter and Gamble researcher Greg Allgood says cases of diarrhea(腹瀉) in those studies fell by about 50 percent. Researchers from Johns Hopkins University in Maryland tested the system at a refugee camp in Liberia. Mr. Allgood says that study found a reduction of more than 90 percent. Use of the system is being expanded worldwide.
The treatment contains bleach(漂白劑) to kill disease-causing organisms. It also contains something that dirt and other particles stick to. Mr. Allgood says the chemicals can remove lead and other dangerous metals and even agricultural poisons like D.D.T.
Mr. Allgood heads the Children's Safe Drinking Water program at Procter and Gamble. He says about forty million packets of the treatment have been given to countries for free. They have been used in emergencies and in areas with limited supplies of clean water.
Clean water is a limited resource in many parts of the world. Delegates from about 130 nations attended the Fourth World Water Forum last month in Mexico City. Scientists, policy experts and others discussed ways to provide clean water to the world’s poor. Organizers say more than twenty percent of the world population lacks clean drinking water. The final declaration did not go so far as to declare water a human right. But it did say that governments, not private companies, must take the lead in improving the public’s ability to have clean water.
46. What is mainly talked about in this passage?
A. Water pollution around the world.
B. The causes of diarrhea in African countries.
C. A newly developed water treatment system.
D. The Fourth World Water Forum in Mexico City.
47. Which of the following developed the water treatment system?
A. The US Centers for Disease Control and Prevention.
B. The Procter and Gamble Company and C.D.C.
C. The Children’s Safe Drinking Water Program.
D. Johns Hopkins University.
48. Which of the following about the new water treatment system is NOT true?
A. It is effective but very expensive.
B. It was tested in Guatemala, Pakistan and Kenya.
C. It is being expanded worldwide.
D. It can remove dangerous metals in the water.
49. Which of the following shows that the shortage of clean water is a serious problem?
A. Forty million packets of the treatment have been given to countries for free.
B. Delegates from about 130 nations attended the Fourth World Water Forum.
C. Four grams of chemicals can treat liters of dirty water for a low cost.
D. Infections from dirty water kill several thousand children every day.
50. The best title for this article is ______.
