From childhood to old age, we all use language as a means of broadening our knowledge of ourselves and the world about us. When humans first 1 , they were like newborn children, unable to use this 2 tool. Yet once language developed, the possibilities for human kind’s future 3 and cultural growth increased. Many linguists believe that evolution is 4 for our ability to produce and use language. They 5 that our highly evolved brain provides us 6 an innate language ability not found in lower 7 . Proponents of this innateness theory say that our 8 for language is inborn, but that language itself develops gradually, 9 a function of the growth of the brain during childhood. Therefore there are critical 10 times for language development. Current 11 of innateness theory are mixed, however, evidence supporting the existence of some innate abilities is undeniable. 12 , more and more schools are discovering that foreign languages are best taught in 13 grades. Young children often can learn several languages by being 14 to them, while adults have a much harder time learning another language once the 15 of their first language have become firmly fixed. 16 some aspects of language are undeniably innate, language does not develop automatically in a vacuum. Children who have been 17 from other human beings do not possess language. This demonstrates that 18 with other human beings is necessary for proper language development. Some linguists believe that this is even more basic to human language 19 than any innate capacities. These theorists view language as imitative, learned behavior. 20 , children learn language from their parents by imitating them. Parents gradually shape their child's language skills by positively reinforcing precise imitations and negatively reinforcing imprecise ones. 请在7处填上正确答案（）

Passage Four
More 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. From the first paragraph we can infer that in the US schools ______.
A. students enjoy shooting
B. students are eager to be solider
C. safety is a problem
D. students can make guns
正确答案：C46．答案为C。根据第一段，for bringing guns and bombs to school作出该项选择。

Old Man Myths and Realities
1 When does a middle-aged man become an old man?Officially,of course,it's when we
reach retirement age. But, as we all know, this is a fairly blunt（生硬的）method of
decision making. As life expectancy（预期寿命）increases, retirement planning needs to
be changed .This is because being an old man today is very different from what it was a
generation or so ago.
2 Sixty-five is the new middle-aged man. These days people are talking about the young-
old,that is ages 70-75,and those over 75 as the old-old. The young-old frequently
continue in good health and maintain strong links with friends and family.The old-old have a
much higher chance of poor health and social isolation.
3 Although men are living longer,there are still more old women than old men.This fact
alone should arouse interest as to why.Relatively little is actually known about why this is
the case or about the experiences of the old man .Sure,we are aware that the old man
experiences anxiety,financial problems,loneliness,etc.,but that's really about all we
know.
4 It is usually believed that the old man often complains about their health.In fact,most
rate their health as good even though most are diagnosed with at least one chronic illness.
The physical health of the old man is strongly affected by their health behavior when they
were younger.Nowadays men generally live longer than_________.
A: in good health
B: in the past
C: in the wrong
D: the old man
E: a middle-aged man

Eat to Live
A meager diet may give you health and long life,but it's not much fun-and it might not even be necessary.We may be able to hang on to most of that youthful vigor 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 won't reverse other damage caused by time for the mouse,but could help its liver metabolize 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-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-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 ol- der,our bodies are less efficient at metabolizing drugs,for example.A brief period of time of die- ting,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.答案：D解析：第一段第一句讲“节食可能不是非做不可的事”，第二句讲“即使上了年纪再节食，我们仍然有可能在很大程度上保持青春活力”，因此，“我们必须从小就开始节食”是错误的，D是正确答案。
第二段提及“一只高龄老鼠”的时候，作者谈到，“只要连续四周限制它进食，它的肝脏基因就会变得和衰老前一样充满活力”。据此，“为了描述节食对老鼠所产生的影响”最好地回答了题干中的问题。
第四段提到，“正常饲养的老鼠随着年龄的增长有46条肝脏基因会发生变化，这种变化与炎症和有机体组织无限激增有关”，因此D正确。
第四段最后一个句子讲“但最惊人的发现是那些上了年纪才开始节食的老鼠也能从70%的基因变化中受益”。“最惊人的”自然是“最令研究人员感兴趣的”。
文章的最后两段谈及Spindler时节食的看法。首先，他不能肯定节食是否值得。其次，他希望在不久的将来，我们不必节食。所以我们可以推知，他认为节食不是得以健康长寿的好办法。 -
