我们需要特别注意以下几种情况和句型结构:
1.一般现在时可以代替将来时,用于时间和条件状语从句中。例如:
1)Return the book immediately to the library as soon as you _____ it.
A. finish
B. are finished
C. have finished
D. are finishing
答案A。
2)Please be sure to telephone me the next time you _____.
A. will come
B. would come
C. shall come
D. come
答案D。
2.在“This is the first time…”结构中,后面的从句用现在完成时。
句子开头也可以用it代替this
例:This is the first time that I have met Jane.
3.在“It/This is +形容词最高级+名词后面的从句中,用现在完成时。”
例:This is on
A. that have ever been written
B. which have ever been written
C. that has ever been written
D. whatever have been written
答案为A。
4.在“It is/has been+时间段+since…后边用过去时。”
例:It has been twenty years since I left my hometown.
5.在“no sooner…than”和“hardly… when…”结构中,主句部分用过去完成时,从句部分用过去时。例如:
1)I had no sooner returned than he called.
2)We had hardly begun when we were told to stop.
6.在“It is (high) time后边的从句中用过去时。”
例:It is time that we had a rest.
