Passage Four “Family” is of course an elastic word.But when British people say that their society is based on family life,they are thinking of “family” in its narrow,peculiarly European sense of mother,father and children living together alone in their own house as an economic and social unit. Thus,every British marriage indicates the beginning of a new and independent family—hence the tremendous importance of marriage in British life. For both the man and the woman,marriage means leaving one`s parents and starting one`s own life.The man`s first duty will then be to his wife,and the wife`s to her husband.He will be entirely responsible for her financial support,and she for the running of the new home.Their children will be their common responsibility and theirs alone.Neither the wife`s parents nor the husband`s,nor their brothers or sisters,aunts or uncles,have any right to interfere with them—they are their own masters. Readers of novels like Jane Austen`s Pride and Prejudice will know that in former times marriage among wealthy families were arranged by the girl`s parents, that is,it was the parents` duty to find a suitable husband for their daughter,preferably a rich one,and by skillful encouragement to lead him eventually to ask their permission to marry her.Until that time,the girl was protected and maintained in the parents` home,and the financial relief of getting rid of her could be seen in their giving the newly married pair a sum of money called a dowry.It is very different today.Most girls of today get a job when they leave school and become financially independent before their marriage.This has had two results.A girl chooses her own husband,and she gets no dowry. With regard to marriage in Britain, present day girls differ from former time girls in （）
Passage Two Overhead bridges are found in many parts of Beijing, especially in places where traffic is very heavy and crossing the road is dangerous. The purpose of these bridges is to enable pedestrians (行人) to cross roads safely. Overhead bridges are used to very much the same way as zebra crossings. They are more efficient (效率高的) although less convenient because people have to climb up a long flight of steps. This is inconvenient especially to older people. When pedestrains use an overhead bridge, they do not hold up traffic. However, when they cross a busy road using a zebra crossing, traffic is held up. This is why the government has built many overhead bridges to help pedestrians and to keep traffic moving at the same time. The government of Beijing has spent a large amount of money on building these bridges. For their own safety, pedestrians should be encouraged to use them instead of risking (冒…危险) their lives by dashing across the road. Old people , however , may find it a little difficult climbing up and down the steps, but it is still much safer than walking across the road with all the danger of moving traffic. Overhead bridges serve a very useful purpose. Pedestrians, both old and young, should make it a habit to use them. This will prevent unnecessary accidents and loss of life. The underlined words a zebra crossing probably mean（）
Passage 1Is that 6 a.m. workout getting in the way of good sleep Don’t think your fat cells won’t notice. A new study published in The Annals of Internal Medicine (a medical journal) finds that inadequate shut-eye has a harmful effect on fat cells, reducing their ability to respond to insulin (胰岛素) by about 30 percent. Over the long-term, this decreased response could set the stage for type-2 diabetes (a medical condition in which someone has too much sugar in his or her blood), fatty liver disease and weight gain.The study adds to a growing body of evidence that there’ “an intimate relationship between the amount of sleep we get and our ability to maintain a good, healthy body weight,” says sleep expert Helene Emsellem, director of the Center for Sleep and Wake Disorders in Chevy Chase, Maryland. (76) But Americans don’t seem to be getting the message that we need seven to nine hours par night. More than 1 in 5 of us, according to a report from the Centers for Disease Control and Prevention, is getting six or fewer hours of sleep per night, on average.So how did researchers study fat cells in the Annals paper Matthew Brady of the University of Chicago and a group of colleagues selected and persuaded seven volunteers to take part in the research project. They were all young, thin and healthy and agreed to sleep for eight nights in a sleep lab. “For four nights they were allowed to stay in bed for 8.5 hours a night,” says Brady. Then, a month later, they came back for four additional nights——but this time they were allowed just 4.5 hours of sleep per night. And after each visit, researchers got a sample of their fat. (77) Brady explains that the fat cells responded significantly to the loss of sleep. “I was very surprised to be honest,” he says.Bad things can happen when fat cells become less responsive to insulin. “Fat cells are actually your friend,” he says. “They’re there to store lipids (血脂).” When lipids stay inside the cells, your body can utilize the fat when you’re exercising or sleeping or going about your day. “However, when fat cells stare to become insulin resistant, the lipids star to leach out of the fat cells and rise in the bloodstream,” Brady says. According to the passage, lack of sleep for a long while can probably lead to all of the following EXCEPT（）
