高三英语复习与训练十二一——动词的语态12. 动词的语态 语态有两种：主动语态和被动语态。主语是动作的发出者时为主动语态；主语是动作的接受者时为被动语态。注意：1）感官动词主动语态的宾语补足语是不带 to 的不定式，变为被动语态时，该不定式前要加"to"。例如：The teacher made me go out of the classroom. 老师逼我走出教室。--> I was made to go out of the classroom （by the teacher）. We saw him play football on the playground. 我们看见他在草场踢球。--> He was seen to play football on the playground. 2）情态动词+ be +过去分词，构成被动语态。例如：Coal can be used to produce electricity for agriculture and industry. 煤可以产生工农业需要的电。 12.1 let 的用法 1）当 let 后只有一个单音节动词，变被动语态时，可用不带 to 的不定式。例如：They let the strange go.他们放陌生人走了。---> The strange was let go. 2）当 let 后宾补较长时，let 通常不用被动语态，而用 allow 或 permit 代替。例如：The nurse let me go to see my classmate in the hospital. 那护士让我去探望住院的同学。----> I was allowed / permitted to see my classmate in the hospital. 12.2 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。例如： My sister will be taken care of by Grandma. 我妹妹由奶奶照顾。 Such a thing has never been heard of before. 这样的事闻所未闻。 12.3 表示"据说"或"相信" 的词组，基本上由 believe, consider, declare, expect, feel , report, say, see, suppose, think, understand 等组成。例如： It is said that… 据说 It is reported that… 据报道 It is believed that… 大家相信 It is hoped that… 大家希望It is well known that… 众所周知 It is thought that… 大家认为It is suggested that… 据建议 It is taken granted that… 被视为当然 It has been decided that… 大家决定 It must be remember that… 务必记住的是 12.4 不用被动语态的情况 1） 不及物动词或不及物动词短语，如 appear, die disappear, end（vi. 结束）,...
