In the early days of sea travel, seamen on long voyages lived exclusively on salted meat and biscuits. Many of them died of scurvy (坏血病), a disease of the blood which causes swollen gums, livid white spots on the flesh and general exhaustion. On one occasion, in 1535, an English ship arrived in Newfoundland with its crew desperately ill. The men??s lives were saved by Iroquois Indians who gave them vegetable leaves to eat. Gradually it came to be realized that scurvy was caused by some lack in the sailors?? diet and Captain Cook, on his long voyages of discovery to Australia and New Zealand, established the fact that scurvy could be warded off by the provision of fresh fruit for the sailors.

       Nowadays it is understood that a diet which contains nothing harmful may yet result in serious disease if certain important elements are missing. These elements are called “vitamins”. Quite a number of such substances are known and they are given letters to identify them, A, B, C, D, and so on. Different diseases are associated with deficiencies of particular vitamins. Even a slight lack of Vitamin C, for example, the vitamin most plentiful in fresh fruit and vegetables, is thought to increase significantly our susceptibility (敏感度) to colds and influenza.

The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruit and green vegetables. It is only when people try to live on a very restricted diet, say during extended periods of religious fasting (斋戒), or when trying to lose weight, that it is necessary to make special provision to supply the missing vitamins.

[1] As adolescents(青少年), having a meaningful effect on the world can seem like an impossible task for the simple fact of being kids.  Changing the world does not only mean finding a cure for cancer, eliminating poverty, or finding the origin of humanity, but recycling a piece of paper as well. Going Green is a practical way that adolescents can have a real, meaningful influence in the world.  There are numerous options of how individuals can change their lifestyles to be more eco-conscious(有生态环保意识的). What follows are three simple ways young adolescents can go green and change the world.

1. Recycle

[2] According to a Wire & Twine online article, 63 million newspapers come out every day and of those 44 million are thrown away; recycling the Sunday newspaper alone we could save half a million trees a week.

[3] The age of technology constantly creates new phones, iPods, or new computers.  Many will stand in line for hours if not days to get their hands on the new piece of technology, but what happens with the old ones once they are replaced?  Nothing, according to Earth911 about 75% of the old devices sit in the back of a drawer collecting dust.  By taking them to the local stores that collect them, they go to poor people which in turn removes them from landfills(垃圾填埋场) where the phones explode because of the lead and lithium-ion(锂离子) the phones contain.

2. Go vegetarian one day a week

[4] Instead of breaking down the pros and cons(利弊) of the vegetarian lifestyle into a long boring paragraph, here are some astonishing facts on going vegetarian for only one day.  According to Noam Mohr, a physicist at the New York University, the United States would save 100 billion gallons of water which is enough to supply all homes in New England for about 4 months.

[5] The United States would save 70 million gallons of gas which is enough to fuel all the cars of Canada and Mexico combined and still have some to spare. The United States could prevent 3 million tons of soil erosion(侵蚀), 4.5 million tons of animal wastes, and about 7 tons of ammonia emissions (氨排放). The Environmental Defense concludes with the most interesting fact: if the entire population gives up one meal of chicken, the amount of carbon dioxide accumulated would be the same amount if more than half a million cars were taken off U.S. roads.

3. 第63题

[6] Most drink bottled water because of the common view that bottled water is healthier than regular tap water; actually, 25% of bottled water comes from regular tap water and all that is done extra is it going through a filter(过滤器).  Tap water has higher regulations from the FDA (Food and Drug Administration美国食品药品管理局) than bottled water does.  Companies do not need to list where they got the water from, how they purify the water, or what chemicals their plastic water bottles contain.  Plastic bottles do not get recycled 90% of the time which results in 1.5 million tons of plastic in landfills which take thousands of years to rot.  Not only are you drinking the same water as that in your house but also paying extra.  The average 24-pack of bottled water cost $3.97 at the local Wal-Mart and a reusable water bottle cost between $4.99-$7.99; just imagine how much money could be saved if reusable water bottles replaced plastic water bottles.

[7] Changing the world for a positive has to start somewhere and while it may be hard and at times it may seem as if the small changes that are being done are not affecting the world, keep in mind what Margaret Mead once said, “Never doubt that a small group of thoughtful citizens can change the world; indeed, it’s the only thing that ever has.”

58. What’s the whole passage mainly talked about?

  A. Ways to protect environment.                B. Ways to become powerful.

  C. The importance of recycling.                        D. The importance of saving water.

  A. Changing the world involves many questions.

B. It’s not easy to change the world.

  C. Changing the world is not so difficult.   

D. We can actually do everything.

60. How much of the daily newspapers are thrown away according to Paragraph 2?

  A. About 44%.         B. About 63%.             C. About 70%.            D. About 75%.

61. In the article, the writer _____ to tell us the benefits of the vegetarian lifestyle.

  A. does a lot of reasoning                                 B. uses many facts    

C. borrows VIPs’ phrases                                  D. puts forward new ideas

  A. Much water and gas would be saved.           B. Much land would be spared.

  C. More animals would survive.                         D. More cars would be on the roads.

  A. Drink healthy water                                B. Produce bottled water

  C. Give up bottled water                             D. Reuse tap water

  A. They think it’s cheaper.                                 B. They think it’s healthier.

  C. They think it’s more fashionable.                  D. They think it’s environmental friendly.

  A. We should find a proper time to start action

B. Small changes will make big differences.

  C. Personal efforts will not affect the world.

D. A small group of people matters.

When we think about giving help to developing countries, we often think about giving money so that these countries can build schools and hospitals, buy food and medicine, or find clean water supplies. These seem to be the most important basic needs of the people we are trying to help. However, it's far from enough. Ladies and gentlemen, we've got to come up with some better ideas to help them.

I was very surprised, then, when I read about a plan to make cheap laptop computers for children in developing countries. A man called Nicholas Negroponte invented a cheap laptop computer, which can run without electricity. He decided to invent this computer after he visited a school in Cambodia.

The laptop which Mr. Negroponte has designed is a little different from the normal laptop computers you can buy in the shops. One difference is that it is covered in rubber so that it is very strong and won't be damaged easily. As an electricity supply can be a problem in developing countries, the computer also has a special handle so that children can wind the computer up to give it extra power when needed.

These special laptop computers will cost less than 100 US dollars and Mr. Negroponte wants to build as many as 15 million machines in the first year of production. The idea is that these computers will help the children's education as they will be able to access the Internet. These computers might not help the people in developing countries immediately, but by improving children's education they should help people to find their own solutions to their problems in the long term.

Another idea to help children in developing countries is to recycle old mobile phones so that they can be used again. In the UK, and, probably in many other countries too, millions of mobile phones are thrown away every year. The waste created by throwing away these old phones is very bad for the environment, so it seems to be an excellent idea to recycle them. In this way we will be able to achieve two important goals at the same time. We will reduce the waste we produce and help others. In other words, we will be able to 'kill two birds with one stone', and that is always a good thing.

It's an excellent idea to recycle old mobile phones because _______.

A. it reduces waste and can help others  

B. it prevents waste and can earn lots of money

C. it can send the waste produced by developed countries to other countries

D. it is good for the environment and very educative for phone users

The author gives the example of Mr. Negroponte's cheap computers _______.

A. to show what high tech can bring us.

B. to illustrate the kindness of people in the developed countries

C. to show how to find business opportunities in developing countries

D. to give an example of how to help developing countries

Which of the following statements is TRUE about Mr. Negroponte's cheap computers?

      A. His computers don’t need any power to function well.

      B. His computers are covered with rubber so that they are very cheap.

      C. His computers will help children in developing countries to have better education.

      D. His computers will help people in developing countries to find all the solutions.

Where does this passage probably come from?

      A. A magazine      B. A newspaper        C. A lecture          D. An advertisement
