【要點(diǎn)精講】

一、現(xiàn)在進(jìn)行時(shí)的被動(dòng)語態(tài)的基本結(jié)構(gòu)：

現(xiàn)在進(jìn)行時(shí)態(tài)的被動(dòng)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(gè)問題現(xiàn)在正在會(huì)上被討論。

二、現(xiàn)在進(jìn)行時(shí)的被動(dòng)語態(tài)的主要用法：

1. 現(xiàn)在進(jìn)行時(shí)的被動(dòng)語態(tài)同它的主動(dòng)語態(tài)一樣，表示現(xiàn)在正在進(jìn)行的被動(dòng)動(dòng)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(jìn)行時(shí)的被動(dòng)語態(tài)同它的主動(dòng)語態(tài)一樣，表示現(xiàn)階段正在進(jìn)行的被動(dòng)動(dòng)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(dòng)物，它們很快就會(huì)消失。

3. 少數(shù)及物動(dòng)詞的進(jìn)行時(shí)表示按計(jì)劃、安排將要承受某個(gè)動(dòng)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(shí)候舉行運(yùn)動(dòng)會(huì)？

三、特別提醒：

1. 一些表示“狀態(tài)、心理活動(dòng)、擁有、存在”等的動(dòng)詞，一般不用現(xiàn)在進(jìn)行時(shí)的被動(dòng)語態(tài)，常用一般現(xiàn)在時(shí)的被動(dòng)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(jìn)行時(shí)的被動(dòng)語態(tài)的含義。如：

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

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