1A.would   B.be used to  C.used to   D.used
解析:句意:但是人们现在比过去寿命长。used to表示“过去经常做……”,暗示现在并不如此,此处指过去的情况,正好与句意相符。would可表示“过去经常”,但不含“今昔对比”之意。注意该词组与be used to的区别,后者意为“习惯于……”,to为介词。D项之所以不对,是因为在以下词组中,当不定式省略时,通常要保留不定式符号to,如:used to,be going to,mean to,ought to,try to,plan to等。
2A.function   B.effect  C.affect  D.sign
3A.lead in  B.give in  C.run into   D.result in
解析:根据主句内容,which引导非限制性定语从句,which表示前面的“衰老的结果”,即:衰老的结果最终导致死亡。result in“使发生,导致”;lead in无此搭配,在表示“导致”时,应为lead to;give in “让步,屈服”;run into“陷入”,常指陷入困境。
4A.hands  B.feet  C.heart  D.organs
5A.do  B.has done  C.did  D.had done
解析:此句中的did是用来代替前面的动词function,以避免重复。因为这里有一个表示过去的时间状语in childhood and teenage years,所以只能用一般过去时。
6A.energy  B.protection  C.vigor  D.power
7A.likely  B.probable  C.possible   D.alike
解析:likely,possible和probable它们三者都表示“可能”,均可以构成:It is possible/probable/likely+that从句。但probable和possible不能用于sb.is possible/probable to do sth.句型中。alike“相似的”,不符合句意。
8A.attend to   B.contribute to   C.add to   D.devote to
解析:句意:有一些相关的原因可能促使人衰老。contribute to“有助于,起作用,促成”,此意义符合题意。attend to“专心于”;add to“增加,把……添加到……”;devote to“致力于,献身于”。这四个词组中的to都是介词,要注意它和不定式符号to的区别。
9A.replaced   B.reborn     C.recovered    D.surrendered
解析:此句与下文相对应,根据下文第十一空之后出现的replace (代替)可确定该空选replaced;reborn“新生的,复活的”;recovered“恢复”;surrendered“屈服”。
10A.a number   B.the amount    C.the number   D.a great deal
解析:根据此句的谓语动词decreases可确定其主语应为the number,表示“……的数量”,作主语时,应该使用单数的谓语动词;a number of“许多,大量”常用来修饰复数名词,作主语时,要使用复数谓语动词;the amount of“……的数量是”,常接不可数名词;a great deal of“大量的”,后接不可数名词。
11A.The others   B.The other    C.Another    D.Other
解析:根据这一段里谈到的不同情况的细胞,上文用了some cells of the body不能再生,很显然下文中用other body cells可以被新的细胞所代替。这样other与上文的some相呼应。其他词都不能起此作用。
12A.old  B.left  C.new  D.other
解析:根据上文的意思,这里还在继续谈论第二种可再生细胞,即:the new cells。
13A.to  B.for  C.of  D.in
解析:be capable of是固定搭配,表示“有……的能力”。句意:老年人的新细胞的发展能力不如年轻人的强。其他介词不与capable搭配。
14A.factor   B.effect   C.reason   D.element
15A.for themselves   B.of themselves    C.themselves   D.on their own
16A.change   B.to have changed     C.to change    D.to be changed
解析:本句是被动句式,其主动句式是:It is known that some of the protein chemicals in cells change with age and become less elastic.句意:大家知道细胞内有些蛋白质随着年龄的增大而改变,变得没有那么有弹性。在叙述一般性事物时,动词know之后的不定式不用进行式和完成式。
17A.hangs loose  B.hangs loosely    C.is hanging loosely  D.is hanging loose
18A.increase   B.shrink   C.lengthen   D.decrease
解析:句意:这就是为什么老人的身高会收缩的原因。因此表“收缩”的只有shrink;increase“增加”和lengthen“变长”与题意不符; decrease“减少”,一般强调量的减少,也不符合题意。
19A.pass away   B.pass by   C.pass off   D.pass on
解析:根据上下文内容应选pass on,表示“把……传给另一个,转移”,句中store and pass on information指“储存和传递信息”,符合句意。其他三个选项都不符合句意。pass away“去世”;pass by“经过,从……旁边走过”;pass off“逐渐消失,停止”。
20A.improvement    B.procession     C.approach   D.process
