答案详解

1.[B]【解析】形容词词义辨析。ulterior意为“有意隐瞒的”，ulterior motives 意为“别有用心”。ultimate意为“最终的；根本的”；interior意为“内部的，内心的”；hidden意为“隐藏的；神秘的”。句意：你要小心约翰，我认为他那么慷慨别有用心。

2.[D]【解析】考查副词的用法。a lot作副词用，修饰比较级，意为“很，非常”。a lot of作为短语，一般当形容词用，修饰后面的名词，句子的谓语动词与跟在其后面的代词或名词保持一致。由题意可知，只有将A、B、C中的more去掉才符合题意，否则只能用副词a lot修饰比较级more，即选项D。句意：要是自来水像人们认为的那样危险的话，我们大多数人都会生病。

3.[B]【解析】强调句型。空格后的that引导的从句中有完整的主谓宾结构，由此可推断空格中应填入主谓句，排除选项A。同时强调部分不是主语或宾语成分，因此排除选项D。强调句型是“It is（was）+被强调部分+that（who，whom）从句”，排除选项C。选项B为正确答案，强调状语成分。句意：正是在20世纪60年代两国间的贸易达到顶峰。

4.[D]【解析】考查习惯用语。插入语believe it or not 为固定用法，没有词性变化，意为“行不行由你”。句意：信不信由你，他的发现已经在科学界引起了轰动。

5.[C]【解析】考查近义词辨析。vacate意为“腾出（房间）”。depart意为“分别，离开”；abandon意为“抛弃，放弃”；dispalce意为“取代，使某人（某物）离开原位”。句意：旅馆的房间到中午时必须空出来，但行李可以留给搬运工。
