爱华网（一）被动语态
动词的语态主要分为两种：主动语态与被动语态主动语态指主语是谓语功作的执行者，。者为主动关系。被动语态指主语是谓语动作的承受者，。者为被功关系。

一般过去时：was/were+done
现在进行时：am/is/are+being done
过去进行时：was/were+being done
将来时 ：will/would+be done,be going to be done, be to be done
现在完成时：have/has +been done
过去完成时：had+been done
将来完成时：will+have been done
2被动语态门主功语态一样具有不同时态，其时态的变化取决于时间状语，其时态的变化形式由其助动词be的事态变化形式来体现

（。）主谓一致。
主谓一致指的是句子的谓语动词与其主语在数上必须保持一致，句子的主语是第三人称单数，其谓语动词须用单数，主语是复数，则谓语动词用复数。
1．主谓一致的三个原则。
英语中的主谓一致主要遵循三个原则：意义一致原则、语法一致原则和就近原则。这三个原则常常发生矛盾，但当发生冲突时，意义一致原则为优先考虑的原则。
(1)语法一致原则：
主语和谓语通常是在语法形式上取得一致，即主语是单数形式，谓语动词也应采取单数形式；主语是复数形式，谓语动词也应采取复数形式。
She is a girl．她是女孩。
They are all girls．她们都是女孩。

(2)就近原则：
谓语动词的人称和数由靠近它的主语决定。
There is a book，two pens and three pencils on the desk.
书桌上有一本书，两支钢笔和三支铅笔。
There are two pens，a book and three pencils on the desk.
书桌上有两支钢笔，一本书和三支铅笔。
Either my sisters or my mother is coming.
不是我的姐妹们就是我的妈妈要来。
(3)意义一致原则：
主语形式上是单数，但表达复数意义，那么谓语动词要用复数形式；或主语形式上是复数，但表达单数意义，则谓语动词也采用单数形式。
The police are still running after the murderer.
警察还在追杀人犯。
The news was very exciting.
