九年级Unit 7 Teenagers should be allowed to choose their own clothes.知识点详解

1.语态:

 英语有两种语态:主动语态和补动语态 

  主动语态表示是动作的执行者

  被动语态表示主语是动作的承受者 

   Cats  eat  fish.    (主动语态)猫吃鱼。

 


   Fish  is eaten  by cats. (被动语态)鱼被猫吃。

  被动语态的构成

  由“助动词be +及物动词的过去分词”构成

  助动词be 有人称、数和时态的变化,其变化规则与be 作为连系动词时完全一样。

时态

被动语态结构

例句

一般现在 

am

are +过去分词

is

English is spoken in many countries.

一般过去 

was +过去分词

were + 过去分词

This bridge was built in 1989.

can/should

may  +be+过去分词

must/……

The work must be done right now.

   被动语态的用法

当我们不知道谁是动作的执行者,或者没有必要指出谁是动作的执行者,或者只需强调动作的承受者时,要用被动语态。

  Mother allows me to watch TV every night. 妈妈允许我每晚看电视。

 be allowed to do sth. 被允许做某事(被动语态)如:

  LiLy is allowed to go to Qinzhou. 莉莉被允许去钦州。
