2012届高考英语语法精讲精练教师版(第七讲 动词的时态和语态(18)

discovered

【解析】答案为D。理解句子的意思可知，前面的过去时是虚拟语气现象所导致，所以不

影响宾语从句的时态。后面的意思显然是：迄今为止在科技上的发现。所以用现

在完成时态。

④—What’s that noise?

—Oh, I forgot to tell you. The new machine ________.

A. was tested

tested

【解析】答案为C。根据上文的问话“What’s that noise?”说明回话应该是“机器正在被检测”

所发出的噪声，故选C项。

⑤—I don’t suppose the police know who did it.

—Well, surprisingly they do. A man has been arrested and ______now.

A. has been questioned B. is being questioned C. is questioning D. has

questioned

【解析】答案为B。根据时间状语now可判断出用现在进行时，表示正在发生的动作或存

在的状态。a man是question的动作的承受者，所以要用被动语态，表示正在被

审讯。

⑥He ________as a national hero for winning the first gold medal for his country in the Olympics.

A. regarded

regarded

【解析】答案为B。首先可以判断是被动语态，排除A、C选项。根据句意义“他因为在

奥林匹克里获得了金牌而被认为是国家的英雄。”是“过去”发生而不是“过去的过

去”所发生的事，故选B项。

⑦When he turned professional at the age of 11,Mike_____to become a world champion by his

coach and parents.

A. expected

expected

【解析】答案为C。前面的时间状语从句用的是一般过去时，所以主句也要用过去时态。
