被动语态(Passive Vice)被动语态的基本动词形式是be+v-ed。通过改变be的时态,可以构成不同时态的被动语态。一般过去时的被动语态,其构成为:was / were+及物动词的过去分词。
1. 肯定句: 主语 + was/were + V-ed + (by…)
The news was published by the gvernment.
2. 否定句: 主语 + was/were + nt + V-ed + (by…)
3. 一般疑问句: Was/Were + 主语 + V-ed + (by…)?
The news wasn’t published by the gvernment.
Was the news published by the gvernment?
4. 特殊疑问句: 疑问词 + was/were + 主语 + V-ed + (by…)?
When was the news published by the gvernment?
1. “不及物动词+介词 / 副词”构成的短语动词,变成被动句时,要把它们作为整体看待,介词或副词不可与其动词拆开或漏掉。如: Our hmewrk was handed in yesterday afternn. The huse was fixed up by my father.
2. 含有双宾语的主动句变被动句时,可将主动句中的直接宾语或间接宾语变为被动句中的主语。如果把主动句中的直接宾语(指物)变为被动句中的主语,则需在间接宾语(指人)前加适当的介词t或fr。如: 主动结构: Danny gave me a ticket just nw. 被动结构: A ticket was given t me by Danny just nw. (直接宾语作主语) I was given a ticket by Danny just nw. (间接宾语作主语)
3. 有些动词常用其主动形式表示被动意义,如sell, wash, write等和表示感觉、知觉的系动词feel, sund, taste, smell等。如: This kind f dress sells well. The fish tastes very delicius.
4. 在主动句中, 使役动词(如make等)和感官动词 (如see, watch, ntice, hear等)后面常接不带t的动词不定式作宾语补足语; 但在被动句中,这些词后面的动词不定式都需要带t。如: The bss made us wrk fr ten hurs tday. →We were made t wrk fr ten hurs tday by the bss. Mm heard Ben sing in the next rm. →Ben was heard t sing in the next rm by Mm.
感官动词一感二听三让四看主动句中t 离开,被动句中t回来
