参考答案：
1.正确答案：B
答案解析：句子意思为“科学家能注意到大多数人注意不到的许多事物”。
2.正确答案：C
答案解析：空格前后句子的意思是相反的，由此可知空格处应该用一个表示转折的词。in spite of是介词短语，后面不能跟从句;despite是介词，也不能引导从句。in that意思是“既然，因为”，不符合句意。所以只有C项正确。句意：她通过了考试，虽然她没怎么用功。
3.正确答案：B
答案解析：句中用了but，表示转折，所以A答案错误。either表示“(两个中的)一个”，也不符合句意。neither表示两者都不，符合句意。none是指三者以上的人或物，而句子中说的是the twins，是两个人，所以也不正确。句意：父亲希望这对双胞胎成为医生，但他们没有一人喜欢学医。
4.正确答案：D
答案解析：as if引导的是与现在事实相反的虚拟。
5.正确答案：B
答案解析：at the price of是固定搭配，意思是：以…的价钱。
参考答案：
6.正确答案：A
答案解析：表述永恒的真理或客观规律用一般现在时，不管主句谓语用什么时态。而“地球绕着太阳转”是客观规律，所以选A.
7.正确答案：C
答案解析：reluctant“不愿的，勉强的”：“他非常不愿意去，但他别无选择”，所以，reluctant用于本句合适。Hesitant“踌躇的，犹豫的”;ready“准备好的”;willing“愿意的”。
8.正确答案：A
答案解析：以分数限定的名词做主语时，谓语的单复数应同该名词保持一致，而不管分数是单数还是复数。此句中property(财产)是不可数名词，故用单数形式的动词。
9.正确答案：C
答案解析：nothing…more than是习惯用语，意思为“什么也比不上…更…”。句子意思为：记住，什么也比不上读得太慢更伤害注意力的集中了。
10.正确答案：B
答案解析：本句是带有不定式短语作目的状语的简单句。句意为“许多人都投入了身体锻炼计划，以保持良好的健康”。make a commitment“投入，保证”符合题意。

16.正确答案：B
答案解析：can‘t have done，表示对过去发生情况的否定推测，意为“不可能已经……”。
17.正确答案：B
答案解析：Let‘s do sth.表示“建议做某事”，含听话一方在内，故用 shall we.如果用Let us do sth.结构，则用will you?表示请求对方允许。
18.正确答案：A
答案解析：needn‘t表示“不必要”;mustn’t表示“禁止”;wouldn‘t表示“拒绝”。
19.正确答案：D
答案解析：句子意思为“到目前为止，关于梦游病原因有多种说法”。“关于”用as to，其他in view of “考虑到，由于”;in line with“符合”; apart from“除去”，意思不符合。
