答案与题解：
1 B在四个选项中，add只可以与幻搭配，意为“增加”，正符合上下文的意思。
2 C存四个选项中，A和B显然不符合逻辑，可供考虑的只有C和D。需要考虑的是，exercise这个词，如果作为“体育锻炼”讲是不可数名词，只有作为“一项运动”讲时才是可数名词，根据上下文意思，exercise也不是用来强调体育项且的(没有用复数)，而amount正好与不可数名词连用，number则须与可数名词连用，故应选C。
3 A从语法上分析，主句主语exercise的谓语应该是is not only pleasant but beneficial中间显然应该是一个定语从句，定语从句所缺少的是主语，故应选A。
4 D从语法上分析，one should十动词应该是前面那个主语的定语从句，只是定语从句的宾 语which/that被省略了，而四个选项中只有take可与exercise搭配，故应选D。
5 A同答这一道题，首先要知道point这个词，既可表达时间(“时刻”)或空间(“地点”)也可表达“程度”的意思，to the point of正是“达到……的地步/程度”的意思，符合上下文要求。
6 C本空格后面的of middle age and beyond提示了本空格要填的词应该是指“人”的词，而且不止-个人，从上下文看，these显然不合适，因为上文并没有特指哪些人，故只有C合适。
7 D本句中is后面应该是表语部分，四个选项中只有of合适，of importance= important，of vital importance = very, very important.
8 B从语法上分析，这个空必须填上一个形容词作question的定语，从上下文分析，只能是hard合适，因为这里的hard= difficult.
9 B前句已经说到，“不同年龄的人从事多少运动是一个难以回答的问题”，显然本句就应
是“个人的差异太大，无法一概而论”，因此选择too是最恰当的。我们都知道，too to的结构具有否定的意义，too great to permit of generalization正是这个意思。
10 A虽然四个选项都可以与on搭配，但act on是“按照……行动”的意思，carry on是“进行”的意思，不符合上下文要求，只有depend on(“取决于……”)和base on(“根据…”)可以考虑，但base是及物动词，应该“base sth. on ”，故只能选择A。
11 C虽然四个选项都可以与as连用，但用法和意义各有不同，refer to sb./sth. as把……说成……;regard sb./sth.她把……当成……;treat sb. /sth. as把……当成……;均不符合上下文的要求，只有serve as(“充当……，作为……”)才在语法上和意义上恰当。
12 D前面A、B、C三个选项的词义分别为“推迟”“保护”“设计”，与上下文意义风马牛不相及，只有D项“测定、确定”才是恰当选项。
13. A前面说到有两个一般性的建议，并且已提到“第一个”，那么“另～个”只能考虑A、B两个选项了。二者都有“另一个”的意思，只是用法不同，another不用冠词，而the other则需要定冠词the，故选A。
14. B四个选项中A、C、D三个选项的意思与上下文相去甚远，只有B项合适。one should
choose是用来做前面主语的定语从句，在定语从句中省略了宾语that/which。
15. C四个选项中只有m可与participate连用，意为“参加”，in的宾语是引导定语从句的关系代词that。
