John's father______mathematics in this school ever since he graduated from Harvard University
A. taught
B. teaches
C. has taught
D. is teaching
参考答案:C。
解题思路:
意思为:约翰的父亲自从哈佛大学毕业后就一直在这所学校读书,这种状态一直持续到现在,所以句子用现在完成时。
I was giving a talk to a large group of people, the same talk I_to half a dozen other
groups before.
A. was giving
B. am giving
C. had given
D. have given
参考答案:C.
解题思路:
凡是表示过去动作之前的动作要用过去完成时态“had done ".根据题意可知had given的动作发生在was giving之前,所以用过去完成时态。
I fell and hurt myself while I ________ basketball yesterday.
A.was playing
B.am playing
C.play
D.played
参考答案:A
解题思路:
考点:动词时态。while “当……时” 引导的时间状语从句与主句的动作同时发生,因此谓语动词要选进行时,又因为从句中有yesterday,所以谓语动词过去进行时符合题意。句意:昨天我在打篮球的时候摔伤了。
When Lily came home at 5 p.m. yesterday, her mother _____dinner in the kitchen.
A.cooked
B.was cooking
C.cooks
D.has cooked
参考答案:B
解题思路:
考点:动词时态。when引导的时间状语从句与主句的动作同时发生。如果从句谓语用过去时,主句谓语动词就用过去进行时。句意:Lily昨天下午五点回家时,妈妈正在厨房里做晚饭。
