A police spokesman said the devices were made safe by explosive experts in the Ardorn district, where a woman was shot in the leg and 13 police officers were injured during a second successive night of violence. Northern Ireland’s police chief had earlier called on community leaders to work together to end the violence. The violence has erupted sporadically throughout a summer of Sectarian tension in northern Belfast. Questions 20 and 21 are based on the following news. At the end of the news item, you will be given 20 seconds to answer the questions. Now listen to the news. 20. Altogether how many people were injured during the violence？ A.1. B.2. C.13. D.14.

People who sleep about seven hours a night live the longest, three huge studies have found, the newest out in the February issue of the journal Sleep. Still, many sleep experts say lots of adults get too little rest, and that can lead to dangerous health problems. In the latest report from Japanese researchers, 104,010 adults were followed for about 10 years. At the start the participants answered questionnaires about their sleep patterns and about their health mental health and lifestyle. habits, which also can affect survival. After accounting for all of these factors, adults getting all average of seven hours had the lowest death rates. Surprisingly, less sleep ,even as little as four hours a night, didn't significantly increase deaths for men and only lowered survival for women if they averagde less than four hours② But adults who slept longer than seven hours, particulary women, were more likely to die during the 10 years. Two other major published studies and a dozen smaller ones came to similar conclusions, says psychiatrist Daniel Kripke, a sleep researcher at the University of California-San Diego School of Medicine. Doctors shouldn't tell all of their patients to get at least eight hours of sleep, he says in an editorial in the journal. Hormonal changes triggered by darkness or other unknown biological effects from long sleep could be affecting survival,③ Kripke，says. But short sleepers may suffer other bad effects. In his brief studies, those sleeping four to five and a half hours did poorly on tests that measure memory, clear thinking and the ability to pay attention, "and they did progressively worse as the week went on," says David Dinges of the University of Pennsylvania School of Medicine. Adults who slept about seven hours performed best, he says. Other small studies have found adults who sleep less than six hours may be at higher risk for some diseases like diabetes and overweight. And sleep deprivation also causes car crashes, Dinges says. "People should get as many hours sleep, p as they need to feel rested," Kripke says, adding that there's no proof that shortening sleep will lengthen life. s1eep need is partly genetic and may be determined by other factors that also influence life span, he says. What can we learn from the passage？ A．Sleep hours is the most important factor affecting survival. B．Going to bed and getting up early improve health. C．Less sleep is more harmful than over sufficient sleep to people. D．People have different demands of sleep hours.
