答案：
91.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.
92.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”。
93.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。
94.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。
95.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。
96.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”。
97.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。
98.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。
99.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。
100.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。
