6. 6. 选择题 　　Graffiti painting is traditionally a daredevil pursuit. Teenagers dodge security guards to put their names on trains and buses. But over the past decade, graffiti has all but disappeared from Britain's cities. Between 2007 and 2012 the number of incidents of graffiti recorded by the British Transport Police fell by 63%. A survey by the Environment Ministry shows that fewer places are blighted by tags than ever. Graffiti are increasingly confined to sanctioned walls, such as the Stockwell ball courts. In time the practice may die out entirely. 　　The most obvious reason for the decline in tagging and train-painting is better policing. Numerous CCTV cameras mean it is harder to get away with painting illegally. And punishments are more severe. A generational shift is apparent, too. Fewer teenagers are getting into painting walls. They prefer to play with iPads and video games. Some have gone to art school and want to make money from their paintings. The Internet means that painters can win far more attention by posting pictures online than they can by breaking into a railway yard. 　　Taggers and graffiti artists mostly grew up in the 1980s and 1990s. Those men—and almost all are men—are now older and less willing to take risks. Graffiti may eventually disappear. But for now the hobby is almost respectable. The former graffiti artists paint abandoned warehouses at the weekend. It has become something to do on a Sunday afternoon—a slightly healthier alternative to sitting and watching football. 　　1.Teenagers are not afraid of being caught by security guards when they put their names on trains and buses. 　　2.Less tags can be found in public places nowadays. 　　3.Because of better policing graffiti decreases. 　　4.Some teenagers go to art school in order to learn to paint walls. 　　5.Taggers and graffiti artists are still willing to take risks.

12. 6. 选择题 　　Is that 6 a.m. wokeout 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. 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. 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. 　　1. According to the passage, lack of sleep for a long while can probably lead to all of the following EXCEPT . 　　A. heart disease 　　B. weight gain 　　C. diabetes 　　2. The main idea of the third paragraph is . 　　A. how to write a medical research paper 　　B. how to avoid sleep loss 　　C. how the research was conducted 　　3. What does the “leach” in the last paragraph probably mean? 　　A. Leap. 　　B. Lead. 　　C. Leak. 　　4. Which of the following is NOT TRUE according to the passage? 　　A. We will be in trouble if our fat cells become less responsive to insulin. 　　B. More and more studies are done to study the link between sleep and weight. 　　C. More than 20% of Americans are not getting enough sleep. 　　5. Which of the following is an appropriate title for this passage? 　　A. Poor Sleep May Lead to Too Much Stored Fat and Disease 　　B. Sleep Experts Had Exciting Findings in a Fat Study 　　C. Americans Should Have More Than Six Hours of Sleep
