We entered the park and I made an 5 for the following day. The park was 6 , so it took us some time to find an available site. That evening, as we finished our dinner, my wife saw two large skunks (臭鼬) walking toward our table. We 7 climbed onto the table and, for the next four hours, waited for them to 8 our camp.
Having survived that night, we were 9 that everything else would be all right. The next day we met with the people who ran the park. They explained our 10 and gave us a beautiful campsite.

In an ideal world, people would not test medicines on animals. Such experiments are stressful and sometimes painful for animals, and expensive and time-consuming for people. Yet animal experimentation is still needed to help bridge vast gaps in medical knowledge. That is why there are some 50 to 100 million animals used in research around the world each year.
3
Europe, on the whole, has the world's most restrictive (严格的) laws on animal experiments. Even so，its scientists use some 12 million animals a year, most of them mice and rats, for medical research. Official statistics show that just 1.1 million animals are used in research in America each year. But that is misleading. The American authorities do not think mice and rats are worth counting and, as these are the most common laboratory animals, the true figure is much higher. Japan and China have even less comprehensive (全面的) data than America.
Now Europe is reforming the rules governing animal experiments by restricting the number of animals used in labs. Alternatives to animal testing，such as using human tissue or computer models, are now strongly recommended. In addition, sharing all research results freely should help to reduce the number of animals for scientific use. At present, scientists often share only the results of successful experiments. If their findings do not fit the hypothesis (假设) being tested, the work never sees the light of day. This practice means wasting time, money, and animals' lives in endlessly repeating the failed experiments.
Animal experimentation has taught humanity a great deal and saved countless lives. It needs to continue，even if that means animals sometimes suffer. Europe's new measures should eventually both reduce the number of animals used in experiments and improve the way in which scientific research is conducted.
（1）What is the main idea of this passage? （ ） A.The success of animal experiments should be ensured. B.A ban on the use of animals in the lab should be enforced.

A.America uses only about 1.1 million lab animals per year. B.Europe does not use mice and rats as lab animals at all. C.Britain does not use as many lab animals as China does.
D.Japan has limited data on the number of lab animals used each year.
Which of the following is mentioned as an alternative to replace animal experiments? （ ） （3）
A.Statistical studies. B.Computer models. C.DNA planted in animals. D.Tissue from dead animals.
（4）What usually happens to unsuccessful animal experiments? （ ） A.They are not made known to the public. B.They are made into teaching materials. C.They are collected for future publication. D.They are not removed from the research topic list.

Exams affect the whole family. As teenagers bury themselves in textbooks, parents have to behave like saints(圣人), ignoring doubts—is he actually studying up there, or just playing online games? Forget any practical help around the house. “He’s sitting at the kitchen table reading the TV guide，” says the mother of a 15-year-old boy. “But when I ask if he can take the rubbish out, he looks very angry and says, ‘But I’m revising’．” Chloe, 16, comes from a large family and finds it is hard to revise. “I become angry easily，” Chloe says.“I camplain to my mum that there’s too much noise and too much mess.”
Beyond these practical considerations, parents are confused about how much they should get involved. Some call for expert help. Others buy lots of practice exam papers. But you may use your
