一要注意被动语态的不同时态
被动语态由“be+过去分词”,其中的助动词 be 根据情况可使用各种不同时态。如:
She is respected by everyone. 她受到大家的尊重。(一般现在时)
The book will be reprinted soon. 这本书很快会重印。(一般将来时)
The road is being repaired. 路正在修整。(现在进行时)
They have been given a warning. 他们受到警告。(现在完成时)
二要注意带情态动词的被动语态
该结构的基本形式为“情态动词+be(或be的适当形式)+过去分词”。这类结构非常有可能作为语境题出现在考卷中。如:
The rules must be obeyed. 这些规章制度必须遵守。
They shouldn’t have been told about it. 这事是不应当告诉他们的。
三要注意非谓语动词的被动语态
1. 不定式一般式的被动语态。由“to be+过去分词”构成。如:
She asked to be given some work to do. 她要求给她一些工作做。
He was the last person to be asked to speak. 他是最后被邀请发言的人。
2. 不定式完成式的被动语态。由“to have been+过去分词”构成。如:
I should like to have been told the result earlier. 我本想让人把结果早点告诉我的。
3. 现在分词一般式的被动语态。由“being+过去分词”构成。如:
I saw him being taken away. 我看见有人把他带走了。
Being protected by a wall, he felt quite safe. 有墙作保护,他感到很安全。
4. 现在分词完成式的被动语态。由“having been+过去分词”构成。如:
Having been invited to speak, I’ll start making preparations tomorrow. 因为邀请我去讲话,我明天就得做准备。
The subject having been opened,he had to go on with it. 话题已经开始了,他不得不谈下去。
5. 动名词一般式的被动语态。由“being+过去分词”构成。如:
She likes being looked at. 她喜欢被人瞧。
He hates being made a fool of. 他讨厌被别人愚弄。
This question is far from being settled. 这个问题远没解决。
6. 动名词完成式的被动语态。由“having been+过去分词”构成。如:
Jenny’s not having been trained as a dancer is her one regret. 杰妮没受过舞蹈的专业训练是她感到遗憾的事。
After having been instructed to drive out of town, I began to acquire confidence. 在接到把车开出城的指令后,我开始信心十足了。
注:过去分词没有被动式,因为它本身可以表示被动意义。如:
The door remained locked. 门仍然锁着。
四要注意“get+过去分词”构成的被动语态
英语被动语态通常由“助动词be+过去分词”构成,有时也可用“get+过去分词”构成。如:
James got beaten last night. 詹姆斯昨晚被打了。
How did that window get opened? 那个窗户是如何打开的?
但总的说来,用get构成的被动语态不如用be构成的被动语态常见,尤其是在含有施动者的by短语时,用get构成被动语态更是少见。不过有时用be+过去分词构成被动语态构成误解时,人们可能会选get+过去分词来避免这种误解:
The window was broken. 窗户破了(表状态)。/ 窗户被打破了(表动作)
The window got broken. 窗户被打破了(表动作)
