还原题干中颠倒的语序，使句子结构明朗，从而作出正确选择。 As a student, every minute should be made full use _____ hard at our lessons. A. of working B. of to work C. of work D. of being worked
解析：把题干还原为主动结构：As a student, we should make full use of every minute to work hard at our lessons. 由此可见，动词不定式 to work hard at our lessons 为目的状语。故最佳答案为 B。
Ｉhave always been honest and direct, and it doesn’t matter ______ I’m talking to. And sometimes they misunderstand me, so I may need to change. A. who is it B. who it is C. it is who D. it is whom
解析：题干 matter 之后为宾语从句，而且含有强调结构。把宾语从句还原：I’m talking to whom, 然后再对 whom 进行强调，Whom is it that I’m talking to，再变为陈述语序，即为答案 D。
