【要點精講】

一、現(xiàn)在進行時的被動語態(tài)的基本結(jié)構(gòu)：

現(xiàn)在進行時態(tài)的被動語態(tài)的肯定式為：am/is/are + being + done。如：

The question is being discussed at the meeting now. 這個問題現(xiàn)在正在會上被討論。

二、現(xiàn)在進行時的被動語態(tài)的主要用法：

1. 現(xiàn)在進行時的被動語態(tài)同它的主動語態(tài)一樣，表示現(xiàn)在正在進行的被動動作。如：

He is being interviewed by the reporter now. 他正在接受記者的采訪。

2. 現(xiàn)在進行時的被動語態(tài)同它的主動語態(tài)一樣，表示現(xiàn)階段正在進行的被動動作。如：

These animals are being hunted at such a speed that they will disappear soon.以這樣的速度捕殺動物，它們很快就會消失。

3. 少數(shù)及物動詞的進行時表示按計劃、安排將要承受某個動作。如：

Some rock music is being played by them next. 下面將由他們演奏一些搖滾音樂。

When is the sports meeting being held in our school？ 我校將在什么時候舉行運動會？

三、特別提醒：

1. 一些表示“狀態(tài)、心理活動、擁有、存在”等的動詞，一般不用現(xiàn)在進行時的被動語態(tài)，常用一般現(xiàn)在時的被動語態(tài)。如：

Xiao Wang， come here. You are wanted on the phone. 小王，過來，有你的電話。

Football is becoming more and more popular. In other words， it is loved by more and more people. 足球現(xiàn)在越來越受歡迎了，換句話說，它被越來越多的人所喜愛。

2. “be +under/ in等介詞+名詞”結(jié)構(gòu)可以表示現(xiàn)在進行時的被動語態(tài)的含義。如：

The problem is under discussion （is being discussed） at the meeting. 這個問題正在會上被討論。

The telephone is in use （is being used） now. 這部電話正在使用中。
