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。
