One day an ant was drinking at a small stream and fell in. She made desperate(拼死的) efforts to reach the side, but made no progress at all. The poor ant almost exhausted(精疲力竭的) was still bravely doing her best. when a dove saw her. Moved with pity, the bird threw her a blade of grass, which supported her like a raft, and thus the ant reached the bank again. While she was resting and drying herself in the grass, she heard a man come near. He was walking along barefooted with a gun in his hand. As soon as he saw the dove, he wished to kill it. He would certainly have done so, but the ant bit him in the foot just as he raised his gun to fire. He stopped to see what had bit him, and the dove immediately flew away.

It will be hot—hot enough that most locals will have cleared town for cooler places. But because athletes competing at the 2004 Olympics have no choice but to stay in the hot weather, many plan to turn to science to stay cool.
Some will put their hands in ice water just before competing and nearly all will be wearing fabrics(织物) designed with hot weather in mind.
“Normally we warm up before exercise,”said Gordon Sleivert, director of sports science and medicine at the Canadian Sport Center in Victoria, British Columbia.“But in this case we're taking the warm out of warm up. It's like pre-cooling.”
Experts are predicting(预测) the average high this August in Athens will be 90 degrees Fahrenheit, with temperatures often reaching above 100(the average temperature in Sydney for the 2000 summer games was 64).
Although some events, such as the marathon, will start early(1 a.m.) to avoid hot weather, other competitors will be pushing their limits during high temperatures. Drinking lots of water will help athletes keep cool, but humidity(湿度) remains a problem. The body's ability to cool down is weakened by damp air since sweat drips off the skin rather than evaporates(蒸发),resulting in dehydration(脱水) without the cooling.
“Getting hot is a real problem because when our brains heats up, the brain waves are more like when you're really sleepy. Everything feels harder,” said Sleivert. The passage mainly tells us that _______.
| A．why it is very hot in Athens |
| B．the hot weather is a big problem for Olympic athletes |
| C．how important science is to every athlete |
| D．the Olympics will be put off because of the hot weather |
The underlined sentence “other competitors will be pushing their limits during high temperatures”in the fifth paragraph means _______.
| A．Olympic athletes will put off their competition time |
| B．some events in the Olympics will have to be put forward |
| C．competitors can't reach their limits in the hot weather |
| D．competitors will have to try their best to compete under any condition |
The following things will be likely to happen in the hot weather EXCEPT _______.
| A．dehydration |
| B．being sleepy |
| C．that the blood in the body can become less and less |
| D．that the body's ability to cool down is weakened |
British men are couch potatoes. They spend nearly half their freetime watching TV. They watch more TV than women, do less housework, less charity work and less childcare—but spend more time shopping, a poll(民意测验) suggests. Analysts(分析家) from Eurostat, the EU's statistical office, interviewed working men and women in 10 countries.
Britain, where men devoted 49% of their freetime to the box, came a narrow second to the Hungarians with 51%.German and Norwegian men watched the least TV—just over one third of their spare time.
The analysts took the average of the figures for the whole year including holidays and weekends. They broke down the “average day” into five categories(类)—free-time, sleep, meals and personal care, travel, domestic chores(家务事) and work or study. It shows that British men have four hours and 41 minutes free time each day—20 minutes more than women. But women spend nearly double the amount of time on domestic chores than men. Almost three-and-a-half hours of a woman's day is taken up with domestic work, compared to less than two hours for men.
Food preparation makes up the bulk(量) of the chores, with leaning and shopping the next most time-consuming. They further broke down the free-time and domestic categories to show that men spend 137 minutes each day in front of the TV, compared to women's 114 minutes.
Women spend slightly more time socializing resting and reading than men, but slightly less time on hobbies, sport and exercise. Universally unpopular with both sexes is culture—accounting for just 2% of both men and women's leisure time.According to the passage, couch potatoes refer to _______.
| A．a kind of potatoes produced in Britain |
| B．people spending much time sitting and watching television |
| C．a kind of food offered by the English people |

What would be the best title for the passage?
| A．Domestic Chores—Only Women's Right |
| B．British Men—Couch Potatoes |
| C．What the Research Means |

Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son, suddenly he seemed to be talking far more to his friends than to his parents. “The door to his room is always shut,” Joanna noted.
Tina and Mark noticed similar changes in their 14-year-old daughter. “She used to cuddle up(蜷伏) with me on the soft and talk,” said Mark.“Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a young lady. The problem is figuring out which time is which.”
Before age 11, children like to tell their parents what's on their minds.“In fact, parents are first on the list,” said Michael Riera, author of Uncommon Sense for Parents with Teenagers.“This completely changes during the teen years.” Riera explained.“They talk to their friends first, then maybe their teachers, and their parents last.”
Parents who know what's going on in their teenagers' lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental break, for children also need freedom, though young.Another thing parents should remember is that to be friend, not a manager, with their children is a better way to know them.“The door to his room is always shut” suggests that the son_______.
| A．is always busy with his studies |
| B．doesn't want to be disturbed |
| C．keeps himself away from his parents |
| D．begins to dislike his parents |
What troubles Tina and Mark most is that _______.
| A．their daughter isn't as lovely as before |
| B．they can't read their daughter's mind exactly |
| C．they don't know what to say to their daughter |
| D．their daughter talks with them only when she needs help |
Which of the following best explains “the wall of silence” in the last paragraph?
| A．Teenagers talk a lot with their friends. |
| B．Teenagers do not want to understand their parents. |
| C．Teenagers do not talk much with their parents. |
| D．Teenagers talk little about their own lives. |
What can be learned from the passage?
| A．Parents are unhappy with their growing children. |
| B．Parents have suitable ways to talk with their teenagers. |
| C．Parents should be patient with their silent teenagers. |
| D．Parents should try to understand their teenagers. |
Common indoor plants may prove to be a valuable weapon in the fight against rising levels of indoor air pollution. Those plants in your office or home are not only pretty, but NASA scientists are finding them to be surprisingly useful in absorbing possible harmful gases and cleaning the air inside modern buildings.
NASA have announced the finds of a 2-year study that suggested the common indoor plants may provide a natural way of helping fight against “Sick Building Syndrome(综合症)”.
Research into the use of biological processes as a means of solving environmental problems, both on Earth and in space habitats, has been carried out for many years by Dr. Bill Wloverton, a senior research scientist at NASA.
Based on preliminary evaluations(初步评估) of the use of common indoor plants for indoor air purification(净化),NASA funded a study using about a dozen popular varieties of attractive plants to determine their effectiveness in removing several key pollutants linked with indoor air pollution. NASA research on indoor has found that living plants are so efficient at absorbing pollutants in the air that some will be launched into space as part of the biological life support system aboard future orbiting space stations.
While more research is needed, Wolverton says the study has shown that common indoor plants can remove certain pollutants from the indoor environment. “We feel that future results will provide an even stronger argument that common indoor plants can be a very effective part of a system used to provide pollution free homes and work places,” he concludes.
“Combining nature with technology can increase the effectiveness of plants in removing air pollutants,” he said.
NASA research has always shown that living, green and flowering plants can remove several poisonous chemicals from the air inside buildings. You can use plant in your home or office to improve the quality of the air to make it a more pleasant place to live and work—where people feel better, perform better, and enjoy life more.The main idea of the passage is _______.
| A．plants are very useful to human beings |
| B．indoor plants can help remove indoor air pollution |
| C．indoor plants should be raised in both homes and offices |
| D．NASA have studied indoor plants for many years |
Why do you think NASA are very interested in indoor plants?
| A．Some indoor plants would be used in space stations. |
| B．They want to find a way to cure Sick Building Syndrome. |
| C．They need indoor plants to carry out their experiments. |
| D．Indoor plants are pretty and attractive. |
The underlined word “pollutants” refers to _______.
| A．some kinds of indoor plants | B．ways to solve air pollution |
| C．research on indoor plants | D．poisonous chemicals in the air |
Artificial(假的) flowers are used for scientific as well as for decorative purposes. They are made from a variety of materials, such as wax and glass, so skillfully that they can scarcely be distinguished from natural flowers. In making such models, painstaking and artistry are called for, as well as thorough knowledge of plant structure. The collection of glass flowers in the Botanical Museum of Harvard University is the most famous in North America and is widely known throughout the scientific world. In all, there are several thousand models in colored glass, the work of two artist-naturalists, Leopold Blaschka and his son Rudolph.
The intention was to have the collection represent at least one member of each flower family native to the United States. Although it was never completed. It contains more than seven hundred species representing 164 families of flowering plants, a group of fruits showing the effect of fungus diseases, and thousands of flower parts and magnified details. Every detail of these is accurately reproduced in color and structure. The models are kept in locked cases as they are too valuable and fragile for classroom use.Which of the following is the best title for the passage?
| A．An Extensive Collection of Glass Flowers |
| B．The Lives of Leopold and Rudolph |
| C．Flowers Native to the United States |
| D．Material Used for Artificial Flowers |
It can be inferred from the passage that the goal of Leopold and Rudolph was to _______.
| A．create a botanical garden where only exotic flowers grew |
| B．do a thorough study of plant structure |
| C．make a copy of one member of each United States flower family |
| D．show that glass are more realistic than wax flowers |
The underlined word “it” refers to _______.
| A．the intention | B．the collection |
| C．one member | D．each flower family |
