这一篇将向各位介绍动词语态的概念和用法。
(看了我们这么多期的文章，不知道大家有什么想法私信我可以点播你最希望学习的语法知识或各式英语技巧，前五位还可以获得一对一定制个人学习计划的机会，赶紧行动吧!!!)
一、什么是语态?有几种?
简单来说，语态就是动词的形式，用来说明主语和谓语间的关系。
语态有两种，主动语态和被动语态。区别在于:在主动语态中，主语是动作的执行者。而在被动语态中，主语是动作的承受者。一般只有及物动词才有被动语态。
例:I eat the cakes.(主动语态:主语I是动作eat的执行者)
The cakes is eaten by me.(被动语态:主语cakes是动作eat的承受者)
二、两种语态如何切换?
1. 最常规的切换方法
找出谓语动词是什么，“be+过去分词”即可表示被动，然后将主语和宾语 的位置互换即可。
例:I throw the ball.主动语态，谓语动词为throw，主语为I，宾语为ball。
The ball is thrown by me. throw变成is thrown,再将I 和ball的位置互换即可。
2. 若宾语补足语是不带to 的不定式，则在变为被动语态时，不定式前要加上''to''。此类动词为感官动词(feel, hear, help, listen to, look at, make, observe, see, notice, watch)。
例:We saw him play basketball on the playground. (see him play, 主动语态中play前不带to)
--> He was seen to play basketball on the playground.(was seen to play，被动语态中play前需要加上to )
3. 情态动词+ be +过去分词，构成被动语态。
Wind can be used to produce electricity.
4. 短语动词的被动语态
短语动词是一个整体，不可丢掉后面的介词或副词。
例:Grandma will take care of my sister. (主动语态中take care of是一个完整的短语动词)
My sister will be taken care of by Grandma.(被动语态中短语动词仍需完整保留)
5. 表示''据说''或''相信'' 的词组
包括:believe， consider， expect，declare， feel ， report， see， say，suppose， think， understand。
It is said that… 据说 It is believed that… 大家相信
It is reported that… 据报道 It is well known that… 众所周知
It is thought that… 大家认为 It is taken granted that… 被视为当然
It has been decided that… 大家决定 It is suggested that… 据建议
It is hoped that… 大家希望 It must be remember that…务必记住的是
三.难点详解
1. 不用被动语态的情况
(1)不及物动词(vi)或动词短语无被动语态:
Vi: appear, die disappear, fail, happen, last, lie, remain, sit, spread, stand
不及物动词短语:break out, come true, fall asleep, keep silence, lose heart, take place.
例:(错) The story was happened last month.
(对) The story happened last month.
(2) 不能用于被动语态的及物动词(vt)或动词短语:
Vt: fit, have, hold,own, marry, wish, cost, notice, watch
及物动词短语:agree with, arrive at / in, ssucceed in, suffer from, hake hands with, happen to, take part in, walk into, belong to
(3) 系动词无被动语态:
appear, be become, get,fall, feel, grow, keep, remain,look, seem, smell, stay, sound, taste, turn
2. 主动形式表被动意义
blame, let, remain, keep, rent, build
例:I was to blame for that.
3. 被动表主动
be determined, be pleased, be graduated (from), be finished, be prepared (for), be occupied (in), get marries
Iam graduated from university. 我毕业于大学。
4. need/want/require/worth
这几个词后面接doing也可表被动
例:The bike need repairing.
