The Pacific island nation of Nauru used to be a beautiful place. Now it is an ecological（生态的） disaster area. Nauru’s heartbreaking story could have one good consequence — other countries might learn from its mistakes.
For thousands of years, Polynesian people lived the remote island of Nauru, far from western civilization. The first European to arrive was John Fearn in 1798. He was the British captain of the Hunter, a whaling ship. He called the island Pleasant Island.
However, because it was very remote, Nauru had little communication with Europeans at first. The whaling ships and other traders began to visit, bringing guns and alcohol. These elements destroyed the social balance of the twelve family groups on the island. A ten-year civil war started, which reduced the population from 1,400 to 900.
Nauru’s real troubles began in 1899 when a British mining company discovered phosphate (磷酸盐)on the island. In fact, it found that the island of Nauru was nearly all phosphate, which a very important fertilizer for farming. The company began mining the phosphate.
A phosphate mine is not a hole in the ground; it is a strip mine（带状矿）. When a company strip-mines, it removes the top layer（层） of soil. Then it takes away the material it wants. Strip mining totally destroys the land. Gradually, the lovely island of Nauru started to look like the moon.
In 1968, Nauru became one of the richest countries in the world. Every year the government received millions and millions of dollars for its phosphate.
Unfortunately, the leaders invested the money unwisely and lost millions of dollars. In addition, they used millions more dollars for personal expenses. Soon people realized that they had a terrible problem — their phosphate was running out. Ninety percent of their island was destroyed and they had nothing. By 2000, Nauru was financially ruined. Experts say that it would take approximately $433,600,000 and more than 20 years to repair the island. This will probably never happen.

German study suggests that people who were too optimistic about their future actually faced greater risk of disability or death within 10 years than those pessimists who expected their future to be worse.
The paper，published this March in Psychology and Aging，examined health and welfare surveys from roughly 40,000 Germans between ages 18 and 96.The surveys were conducted every year from 1993 to 2003.
Survey respondents (受访者) were asked to estimate their present and future life satisfaction on a scale of 0 to 10，among other questions.
The researchers found that young adults (age 18 to 39) routinely overestimated their future life satisfaction，while middleaged adults (age 40 to 64) more accurately predicted how they would feel in the future.Adults of 65 and older，however，were far more likely to underestimate their future life satisfaction.Not only did they feel more satisfied than they thought they would，the older pessimists seemed to suffer a lower ratio (比率) of disability and death for the study period.
“We observed that being too optimistic in predicting a better future than actually observed was associated with a greater risk of disability and a greater risk of death within the following decade，”wrote Frieder R．Lang，a professor at the University of ErlangenNuremberg.
Lang and his colleagues believed that people who were pessimistic about their future may be more careful about their actions than people who expected a rosy future.
“Seeing a dark future may encourage positive evaluations of the actual self and may contribute to taking improved precautions (预防措施)，”the authors wrote.
Surprisingly，compared with those in poor health or who had low incomes，respondents who enjoyed good health or income were associated with expecting a greater decline.Also，the researchers said that higher income was related to a greater risk of disability.
The authors of the study noted that there were limitations to their conclusions.Illness，medical treatment and personal loss could also have driven health outcomes.
However，the researchers said a pattern was clear.“We found that from early to late adulthood，individuals adapt their expectations of future life satisfaction from optimistic，to accurate，to pessimistic，”the authors concluded.
【小题1】According to the study，who made the most accurate prediction of their future life satisfaction?
| A．Optimistic adults. |
| B．Middleaged adults. |
| C．Adults in poor health. |
| D．Adults of lower income. |
| A．to fully enjoy their present life |
| B．to estimate their contribution accurately |
| C．to take measures against potential risks |
| D．to value health more highly than wealth |
| A．They will earn less money. |
| B．They will become pessimistic. |
| C．They will suffer mental illness. |
| D．They will have less time to enjoy life. |
| A．Pessimism guarantees chances of survival. |
| B．Good financial condition leads to good health. |
| C．Medical treatment determines health outcomes. |
| D．Expectations of future life satisfaction decline with age. |

All across California, honeybees are flying away from their hives(蜂箱) and dying. Empty hives are causing a lot of worry about some important food crops.
Bees give us a lot more than delicious honey. They are pollinators（授粉者）—they enable plants to produce the fruits and nuts we enjoy by carrying pollen from one plant or flower to the next. The wind pollinates oats, corn, and wheat, but many other plants (like apple and cherry trees and melon vines) depend on insects, bats, and birds. In the U.S., millions and millions of bees kept by human beekeepers fly around doing a lot of this important work for food crops. “Bees are worth protecting because their work adds so much to our diet,” says Dr. Jeff Pettis of the Bee Research Laboratory.
California’s almond (杏仁) crop alone depends on about half the bees in the country. But now the almond crop and many others could be in trouble with so many bees dying.
Researchers at government and university labs all over the country are trying to figure out why so many bees are dying. However, bees are hard to study. Most die away from the hive, so researchers don’t have dead bodies to examine. And when researchers return to a hive after two weeks, about half the bees they studied on their first visit will be dead, replaced by new ones in the natural life cycle of bees. “It isn’t like studying a large animal like a cow that doesn’t move around much and is easy to find out in the cow field,” says Pettis.
Researchers have some ideas about what could be affecting bee health. They could be sick from poisons widely used to kill insects, or they might not be getting enough good food to stay strong. Also, tiny insects called mites feed on bees. “A virus or bacteria could also be doing the killing.” explains Pettis.
【小题1】What is Paragraph 2 mainly about?
| A．The wind helps pollinate. |
| B．Bees are important in food crops. |
| C．Bees give us a lot of delicious honey. |
| D．Cherry trees are pollinated by bees. |
| A．they move around too much |
| B．new bees soon replace all the bees studied by researchers |
| C．they are too tiny |
| D．they never return to hives |
| A．Poisons to kill birds. | B．Eating too much. |
| C．Large insects. | D．Some virus. |
| A．A large number of bees have died in the hive. |
| B．Without bees, some foods would disappear from our diet. |
| C．Only researchers in California want to know what kills bees. |
| D．Large animals are easier to study than tiny insects. |

It’s the dirty little secret many shampoo companies don’t want you to know. When you wash your hair with certain traditional chemical shampoos, you may actually be removing your hair and scalp（头皮）of their natural oils. These shampoos generate a thick bubble to clean hair, they can also create dryness, curl, dullness, and color fade. We then spend a lot of time and money on products that are effectively repairing the damage caused by shampoo.
Chaz Dean got tired of clients leaving his salon raving about their color and the feeling of their hair---brassy（似黄铜的） and dull. He knew the main cause was likely their shampoo, so he started experimenting with various ingredients, including natural herbs and botanicals, that he knew had cleansing（弄干净）and hydrating (保湿的) properties.
The result was a totally new approach to the way we cleanse our hair. It’s called WEN® Cleansing Conditioner. WEN® contains a super-hydrating natural herbs and botanicals mixture of glycerin, chamomile(甘菊), rosemary, calendula, and Cherry bark, which when combined, will both cleanse the hair as well as give shine and softness, even to damaged hair.

Instead, when mixed with water, it creates a smooth bubble for shiny, healthy-looking, manageable results. The first time you try it certainly feels strange, but the results speak for themselves.
Before being marketed, WEN® went through extensive consumer tests, and the results were impressive. More than 90 percent of the participants in the studies reported that their hair was more shiny, less frizzy, and had more bounce.
WEN® is recommended for all hair types, and once you start using it, it will become the only cleanser/conditioner you will want to include in your daily routine.

It is known to us that computer users are being warned by industry experts to pay attention to secret codes which could be used to record their conversation.
E-mails, screen savers, and electronic greeting cards can carry a secret code which is able to turn on the computer’s microphone, make a recording, and forward it to someone else without the user’s knowledge.
In fact any attachments (附件) sent to a computer, whether it is a game of Space Invaders, or a moving picture, can possibly be used to spy (窥探).
Experts say people should always think twice about opening attachments because --- although not common --- bugging (窃听) by computer can and has been done.
Bill Lyons, head of the Internet Security Company Finjan, said, “People in the army have tested this and you can be sure, if people in general are aware of it, then computer hackers (黑客) are aware of it. The frightening thing is that there are tools on the Internet which people, using a simple search method, can find, and which will enable them to attach this dangerous code to simple attachments.”
【小题1】What is the advice given in the passage?
| A．Use secret codes to record other people’s conversation. |
| B．Be careful when opening an attachment. |
| C．Never open any attachments. |
| D．Never use secret codes. |
| A．nobody seems to believe such things |
| B．nobody knows the danger of the code |
| C．tools can easily be used to tie dangerous codes to e-mails |
| D．effective ways can never be found to deal with the problem. |
| A．A moving picture cannot be used to spy. |
| B．Electronic greeting cards cannot carry a secret code. |
| C．A secret code is used to destroy the computer system. |
| D．Any attachments sent to a computer may carry a secret code. |

Every year in late spring at Wild Friends, the wildlife health center, workers receive baby animals, including songbirds and rabbits. This is the busiest time when workers care for and raise all the little ones before sending them back into the wild.
There are many reasons for these little animals' coming to the center. First of all, street cats or dogs catch, injure or take away little birds from their nests. Sometimes people catch baby animals and keep them at home, giving them food that they are not used to. It would make them sick. Most people don't realize that it's against law to get live animals out of their nests.
As for songbirds, people often find them on the ground in their yards, thinking they have no other choice but to leave them on the ground to die. This is because many people wrongly believe that once a bird is touched by a person, its mother will not accept this child bird. But that's not true.
If a little bird falls out of the nest, you should check whether it is injured. If not, you should put the bird back in the nest. If the bird is injured, call your local wildlife center quickly.
As for the progress of protecting wild animals, people at Wild Friends devote all their energy to this work. Over the last weeks, they have been able to send many of the birds and rabbits that came here earlier this spring back to nature.
【小题1】Which is the busiest season for workers at Wild Friends?
| A．Spring | B．Summer. | C．Autumn. | D．Winter. |
| A．Giving them food they don't like. | B．Letting them play with children. |
| C．Leaving them on the ground. | D．Bringing them to the center. |
| A．wait for its mother | B．help it go back home |
| C．touch it with your hands | D．call workers at Wild Friends |

The Segway Human Transporter was invented by Dean Kamen．It is a two-wheeled vehicle designed for a single rider standing upright over its single axle（轴） and navigate using a set of handlebars resembling those on a bicycle．Electrically powered, it could travel over 15 miles on a single charge and reach speeds up to twelve miles per hour．Its speed and direction can be controlled by riders' changing their weights．
A college dropout and self-taught engineer, Kamen already held over 100 patents for his inventions when he developed the one he hoped would revolutionize short-distance travel．While still in college, Kamen started developing the medical devices （设备） that made his name．Later, he changed focus to the challenges faced by wheelchair users．His robotic wheelchair known as IBOT could climb stairs．This robot ended up paving the way for the Segway．
Before showing his most recent invention, Kamen had kept it a top secret for months．When it turned out to be little more than a motor scooter, many publicly expressed their disappointment．On closer examination, however, even his critics（批评家） had to admit that the vehicle was an engineering achievement．It answered the prayers of anyone who is worn out when walking downtown．Not everyone welcomed the Segway's arrival, though．Some complained it was too expensive, while others said it would further weaken the average American ' s fitness．A Japanese inventor even accused Kamen of stealing the idea for the Segway from him．
Despite the controversy, the U．S．postal service began using Kamen's invention a month after its appearance, and a factory was built with plans to produce about 40,000 Segways every month．The argument is still on whether the Segway will be remembered as the greatest invention since the light bulb, or just another forgettable electronic device．Anyway, trips to the local supermarket will never be the same again．
【小题1】Which statement best describes the critics' reaction to the Segway?
| A．Nothing but an electrical device． |
| B．A disappointing engineering mistake． |

Can dogs and cats live in peace in the same home? People who are thinking about adopting a dog as a friend for their cat are worried that they will fight. A recent research has found a new way for success. According to the study, if the cat is adopted before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along swimmingly. Twothirds of the homes interviewed reported a positive relationship between their cat and dog.
However, it wasn't all sweetness and light. There was a reported coldness between the cat and dog in 25% of the homes, while attacking and fighting were observed in 10% of the homes. One reason for this is probably that some of their body signals are just opposite. For example, when a cat turns its head away it signals attack, while a dog doing the same signals admitting defeat.
In homes with cats and dogs living peacefully, researchers observed a surprising behaviour. They are learning how to talk each other's language. It is a surprise that cats can learn how to talk “dog”, and dogs can learn how to talk “cat”.
What's interesting is that both cats and dogs have appeared to develop their intelligence. They can learn to read each other's body signals, suggesting that the two may have more in common than was previously thought. Once familiar with each other's presence and body language, cats and dogs can play together, greet each other nose to nose, and enjoy sleeping together on the sofa. They can easily share the same water bowl and in some cases groom (梳理) each other.
The advantage of this research on cats and dogs may not only about pets — to people who don't get along, including neighbors, colleagues at work, and even world superpowers. If cats and dogs can learn to get along, surely people have a good chance.
【小题1】The underlined word “swimmingly” in Paragraph 1 is closest in meaning to .
| A．early | B．sweetly |
| C．quickly | D．suprisingly |
| A．they are cold to each other |
| B．they look away from each other |
| C．they understand each other's signals in a wrong way |
| D．they are introduced at an early age |
| A．They eat and sleep together. |
| B．They observe each other's behaviors. |
| C．They learn to speak each other's language. |
| D．They know something from each other's voices. |
| A．We should learn to live in peace. |
| B．We should know more about animals. |
| C．We should live in peace with animals. |

What will people die of 100 years from now？ If you think that is not a simple question， you have not been paying attention to the revolution that is taking place in biotechnology(生物技术). With the help of new medicine， the human body will last a very long time. Death will come mainly from accidents， murder and war. Today's leading killers， such as heart disease， cancer， and aging itself， will become distant memories.
In discussion of technological changes， the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live？ Human brains were known to decide the final death. Cells are the basic units of all living things， and until recently， scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells， such as those of brain cells， would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100， medicine will have advanced to the point at which every 10 years or so， people will be able to take medicine to repair their organs. The medicine， made up of the basic building materials of life， will build new brain cells， heart cells，and so on－in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imaging that the advance in technology may be changing the most basic condition of human existence， but many technical problems still must be cleared up on the way to this wonderful future.
【小题1】According to the passage， human death is now mainly caused by____
| A．diseases and aging | B．accidents and war |
| C．accidents and aging | D．heart disease and war |
| A．heart disease will be far away from us |
| B．human brains can decide the final death |
| C．the basic materials of cells will last forever |
| D．human organs can be repaired by new medicine |
| A．human life will not last more than 120 years in the future |
| B．humans have to take medicine to build new skin cells now |
| C．much needs to be done before humans can have a longer life |
| D．we have already solved the technical problems in building new cells |
