被动语态
Ⅰ.被动语态的构成形式be+Vt.p.p.
(一).语态是英语动词的一种形式，是用于表示主语和谓语之间的关系。英语语态分为主动语态(active voice)和被动语态(passive voice)两种。
主动语态是表示主语是动作的执行者。如：1)Yesterday I parked my car outside the school.
被动语态是表示主语是动作的承受者。2)A sound of piano is heard in the hall.
(二)被动语态的基本时态变化
在被动语态的句子中，谓语部分的结构是be+Vtp.p.(及物动词过去分词)。其中be是变量，随时态的变化而变化;动词的过去分词是常量，永远不发生变化。当然，这只是指谓语部分而言。be动词作为一个独立的谓语动词有自己现在分词(being)和过去分词(been)。那么，下面我们来看看be在各种时态中的变化形式：被动语态通常为八种时态的被动形式。以do为例，各种时态的被动语态形式为：
1)am/is/are+done(过去分词)一般现在时
2)has/have been done 现在完成时
3)am/is/are being done 现在进行时
4)was/were done一般过去时
5)had been done 过去完成时
6)was/were being done 过去进行时
7)shall/will be done 一般将来时
8)should/would be done 过去将来时
Ⅱ.一般来说，在我们日常生活中，能用主动语态的时候就尽量不去用被动语态。只有在下列情况中我们才用被动语态：
英语里被动语态的使用似乎比汉语要广泛。英语的被动语态常用在下列的场合：1)当我们不知道动作的执行者的时候，如：1.Look!There’s nothing here.Everything has been taken away.
2.My car has been moved!
2)当我们不必提出动作的执行者的时候，如：I was born in 1960.
3)当我们强调或侧重动作的承受者的时候，如：She is liked by everybody.
Ⅲ.特殊的被动结构
1)带情态动词的被动结构：它的固定句式为“情态动词+be+过去分词”。也有个别带to的情态动词例外，如：ought to 和have to，它们的被动结构就只能在不定式中。例如：The debt must be paid off before next month那笔债务必须在下个月前付清。
2)带有两个宾语的主动语态变成被动语态
将这种主动态的句子完成被动态的句子，可选两个宾语中的任何一个作为被动态句子的主语，而将另一个宾语作为“保留宾语”写入被动态的句中。但有一点要说明，那就是，如果你选直接宾语作“主语”，有时要在被动态句子的“保留宾语”前加上合格的介词。因为这些动词常有两种句式，即：我们可以说give sb.sth.,send sb.sth.,buy sb.sth;我们也可以说give sth to sb,send sth to sb buy sth for sb。请看下面两种情况的对照：
She sent me a novel on my birthday.
I was sent a novel on my birthday.
A novel was sent to me on my birthday.
3)关于带有复合宾语的主动态变成被动态
如果将带有复合宾语(既：宾语+宾语补足语)的主动语态的句子变成被动语态的句子，我们只能选择原来句子的宾语作被动语态句子的主语;而这时，原句里的宾语补足语现在就变成被动语态句子的“主语补足语”了。
The story made us laugh.(宾语补足语)
We were made to laugh by the story.(主语补足语)
4)在使役动词have，make，get以及感官动词see，watch，notice，hear，feel，observe等后面不定式作宾语补语时，在主动结构中不定式to要省略，但变为被动结构时，要加to。
Someone saw a stranger walk into the building.
A stranger was seen to walk into the building.
有些相当于及物动词的动词词组，如“动词+介词”，“动词+副词”等，也可以用于被动结构，但要把它们看作一个整体，不能分开。其中的介词或副词也不能省略。例The meeting is to be put off till Friday.
6)非谓语动词的被动语态。v+ing形式及不定式to do也有被动语态 (一般时态和完成时态)。例,I don’t like being laughed at in the public.There are two more trees to be planted.

laugh等动词连用,多用于比较级,须放在动词之后。如:
