这是一篇科普类短文。本文讲述的主题是“尽管人的寿命在延长，但随着岁月的流失，人人都会衰老，最终将面临死亡”。
1. C 根据句意：但是人们现在比过去寿命高。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，正好与句义相符。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。
2. B 根据下文中的定语从句所表示的意义进行判断，这里所填入的单词应该表示“衰老的结果”这一意义。effect意为“结果，影响”，正是此意。function“功能，机能，作用”；affect“影响，感动”，是动词；sign“标记”。解题时要注意effect和affect拼写只相差一个字母，但effect是名词而affect是动词。
3. D 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。
4. D 根据上下文及信息词cells可确定句中是指所有的部位(器官)。而其他三项所指的都是身体的具体部位。
5. C 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。
6. B protection“保护，保护物”，和介词against或from连用，译为“保护……免遭……”。此句义为“身体此时的免疫力下降，易于患病”；energy“精力，活力”； vigor“力量，活力”；power“权力，力气”。
7. A 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。如：It will be possible / probable / likely for you to get there before eight o'clock.你有可能在8点钟之前赶到那里。 You will be likely to get there before 8 o'clock. 你很有可能在8点钟之前赶到那里。alike“相似的”，不符句意。
8. B 根据句义：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”，此意义符合句义。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。
9. A 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”
10. C 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，做主语时，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。
11. D 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。
12. C 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。
13. C be capable of是固定搭配，表示“有……的能力”。句中指：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。
14. A 这一段的内容是和上段相对应的，所需词相当于上段第一句中的cause，指造成一种事实或现象的原因，所以选用factor，表“因素，要素”。其他几个词虽然语义相近，但所强调的重点并不相同。effect“结果”；reason“原因”，用来说明一种看法或行为的理由；element“元素”。
15. C 此句意是：另一个导致衰老的因素是细胞内本身的变化。由此可得出，空格处需填一个作同位语的名词或代词，那么四个选项中，就只有themselves可担当此任，即：反身代词themselves做cells的同位语。
16. C 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。意为：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。又如：It is known that a new hospital will be built here. = A new hospital is known to be built here。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。
17. A hang在这里是用作系动词，后面须接一个形容词作表语，类似的动词还有： rise，shine，sit，lie等，如：The sun rose red． (= The sun rose and it is red．)。本句除了要注意hang是系动词外，还要注意时态的选择。因为通篇文章所谈论的是人人都要变老的客观事实，所用时态都为一般现在时，不能用进行时。
18. B 根据句义“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1engthen“变长”与句义不符； decrease“减少”，一般强调量的减少，也不符合题义。特别说明的是shrink这个词平常用得不太多，但它仍然是中学英语“新课标”词汇，它的过去式形式是shrank或shrunk，过去分词形式是shrunk 或shrunken。
19. D 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句意。pass away“去世”；pass by“经过，从……旁边走过”；pass off“逐渐消失，停止”。
20. D 从通篇文章所叙述的人的衰老的过程分析，我们应该在此处选填process。表示“自然的过程，进程”，符合上下文意义；即：衰老可能影响这种进程和改变信息；improvement“改良”；procession“队伍，行列”；approach“方式，方法”。

语篇定位: 这是一篇议论文，作者论述了电视网络购物得以流行的原因，并得出电视网络购物与商场购物将并存的结论。
思路引导: 文章以Have you ever had to decide whether to go shopping or stay home and watch TV on a weekend开篇，引出电视网络购物这一主题，接着陈述电视网络购物的优点，最后指出电视网络购物与商场购物这二者的发展前景。
答案与解析
1. D考查语境理解。网络购物时代，人们购物和看电视两不误，能同时做到。
2. B考查生活常识。一般情况下人们购物要去商店，而网上购物只需在家就可以进行。说明电视网络购物也是人们购物的一种方式。
3. A考查行文逻辑。这里用ever表示强调甚至，曾经，句意为：甚至不用离开自己的家就可以购物。
4. C考查语境理解。破折号后面的内容是人们不愿意做的，所以用 be tired of 厌烦。
5. A考查词语辨析。Fight the crowds指人群熙熙攘攘。
