探究三、语法精讲
一般现在时的被动语态
1.语态
语态是动词的一种形式,用于说明主语和谓语之间的关系。英语中的语态有两种:主动语态和被动语态。主动语态表示主语是动作的执行者;被动语态表示主语是动作的承受者。被动语态中的执行者可由介词by引出。如:
Lots of students love this English song.许多学生喜爱这首英文歌曲。(主动语态,句子的主语lots of students是动作love的执行者)
→This English song is loved by lots of students.(被动语态,句子的主语this English song是动作love的承受者)
2.一般现在时的被动语态的构成
被动语态由“助动词be+及物动词的过去分词”构成,其中的助动词be有人称、数和时态的变化。一般现在时的被动语态的各种句式如下:
句式
构成
例句
肯定句
主语+am/is/are+及物动词的过去分词(+其他)
English is widely used all over the world.
否定句
主语+am/is/are+not+及物动词的过去分词(+其他)
The uniforms are not worn by students every day.
一般疑问句
Am/Is/Are+主语+及物动词的过去分词(+其他)
Are you asked to stay at the room alone?
3. 主动语态变被动语态的方法
把主动语态的句子转换为被动语态的句子,需遵循以下几个步骤:先找出谓语动词;再找出谓语动词后的宾语;把宾语用作被动语态句子中的主语(宾语若是人称代词,须将宾格变为主格);再将主动语态的句子中的主语置于介词by之后(主语若是人称代词,须将主格变为宾格);注意人称、时态和数等的变化。如:
We plant trees every year. 我们每年种树。
→Trees are planted (by us) every year.
4.注意事项
(1) 不及物动词(短语)如happen,rise,appear,come out,take place等没有被动语态。
(2) 动词短语如talk about,pay attention to,take care of等在变为被动语态时,其中的介词不可漏掉。
(3) 在主动语态的句子中,感官动词和使役动词后面接省略to的动词不定式;但在变为被动语态时,不能省略to。
(4) 有些动词的主动语态形式可以表示被动意义。如:
These books sell well.这些书卖得很好。
