Answer 1

21.C， 分析：前一句的逻辑主语是人we，所以是主动语态，因此可以排除D, B句意不符，A 没有这么搭配的，只有C符合。make a purchase 是固定搭配。
22B分析，根据句子的时间状语 for a few weeks,排除D，open 是瞬间动词不可和for引导的时间状语连用，因此C也排除，对于A选项来说，hold 和open都是动词，不可共存。只有B 符合答案。
23.B根据句意，可知其主语是advanc，是单数，因此排除A,依句意，可是是个主动句，所以D排除，C不符题意，那么只剩下B是可行的了。
24C。分析，根据句意可知，第一个动词没有宾语，因此需要个不及物动词，那么排除AD,让步状语是个完成进行时，因此B得以排除，只有C 是符合的。
25. C。分析 A选项里的to是不定式符号，要跟动词原形，因此，A排除，B，D 不符句意，因此只有C 符合答案。
