Passage FourMore than 6,000 children were expelled (开除) from US school last year for bringing guns and bombs to school, the US Department of Education said on May 8.The department gave a report to the expulsions (开除) as saying handguns accounted for 58 percent of the 6,093 expulsions in 1996 and 1997, against 7 percent for rifles (步枪) or shotguns and 35 percent for other types of firearms."The report is a clear sign that out nation's public schools are cracking down (严惩) on students who bring guns to school," Education Secretary Richard Riley said in a statement. "We need to be tough-minded about keeping guns out of our schools and do everything to keep our children safe."In March 1997, an 11 years old boy and 13 years old boy using handguns and rifles shot dead four children and a teacher at a school in Jonesboro, Arkansas. In October, two were killed and seven wounded in a shooting at a Mississippi school. Two months later, a 14 years old boy killed three high school students and wounded five in Dasucah, Kentucky.Most of the expulsions, 56 percent, were from high school, which have students from about age 13.34 percent were from junior high schools and 9 percent were from elementary schools, the report said.46.

共用题干第一篇A meager（不足的）diet may give you health and long life, but it's not much fun一and it might not even be necessary. We may be able to hang on to most of that youthful（有青春活力的）vigor （精力）even if we don't start to diet until old age.Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse's liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation（恢复活力，返老还童） won't reverse other damage caused by time for the mouse,but could help its liver metabolize（使进入新陈代谢过程）drugs or get rid of toxins.Spindler's team fed three mice a normal diet for their whole lives,and fed another three on half-rations.Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old一equivalent to about 70 human years.The researchers checked the activity of 11,000 genes from the mouse livers,and found that 46 changed with age in the normally fed mice.The changes were associated with things like inflammation and free radical production一probably bad news for mouse health.In the mice that had dieted all their lives,27 of those 46 genes continued to behave like young genes.But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 percent of these gene changes."This is the first indication that these effects kick in pretty quickly",says Huber Warner from the National Institute on Aging near Washington D.C.No one yet knows if calorie restriction works in people as it does in mice,but Spindler is hopeful."There's attracting and tempting evidence out there that it will work,"he says.If it does work in people,there might be good reasons for rejuvenating the liver. As we get older,our bodies are less efficient at metabolizing drugs,for example.A brief period of time of dieting,says Spindler,could be enough to make sure a. drug is effective.But Spindler isn't sure the trade-off is worth it."The mice get less disease,they live longer,but they're hungry,"he says."Even seeing what a diet does,it's still hard to go to a restaurant and say:I can only eat half of that."Spindler hopes we soon won't need to diet at all. His company,Lifespan Genetics in California, is looking for drugs that have the effects of calorie restriction.According to the passage,which of the following is NOT true?A:Eating less than usual might make us live longer.B:If we go on a diet when old,we may keep healthy.C:Dieting might not be needed.D:We have to begin dieting since childhood.
We live in a materialistic society and are trained from our earliest years to be acquisitive（贪婪的）.Our possessions,“mine”and“yours”,are clearly（ ）from early childhood.When we grow older enough to earn a living,it does not surprise us to discover that success is measures in terms of the money we earn.A.signedB.notedC.impressedD.labeled
