容易出錯的被動語態時態

請看看這道題：

—Have you moved into the new house?

—Not yet. The rooms __________.

A. are being painted    B. are painting              C. are painted               D. are being painting

此題選A。從句意上看，此題應選被動式(這是顯然的)，同時注意：被動語態要用現在進行時形式(這點容易忽視)。

在做動詞的語態題時，同時要注意其時態形式：

You are wanted on the phone. 有人給你打電話。(一般現在時)

When was the building completed? 這座大樓什么時候建成?(一般過去時)

You won’t be allowed to take so much luggage with you. 不會準你帶這么多行李。(一般將來時)

A new railway is now being built. 一條新鐵路正在修建。(現在進行時)

The roads were being widened. 道路當時正在加寬。(過去進行時)

Such a thing has never been heard of before. 這種事以前從未聽說過。(現在完成時)

有時被動式動詞可與情態動詞連用：

The work must be finished at once. 這工作必須馬上完成。

The method can still be improved upon. 這方法還可以改進。

My umbrella may have been left on the train. 我的傘可能忘在火車上了。
