展开语态用来表示主语与谓语之间的关系。 1.主动语态表示主语是动作的执行者 2.被动语态表示主语是动作的承受者
1. 当我们不知道动作的执行者,或者没有必要指出动作的执行者时。Every classrm in this schl is being equipped with a new TV set.在这所学校里,每间教室都正在装备一台新的电视机。Give bld if yu can and many lives will be saved.如果可以的话,请献一点血,很多生命将会因此而获救。2. 为了强调动作的承受者时。Traditinal flk arts f Tianjin like paper cutting are being exhibited at the culture shw nw.剪纸等天津民间传统艺术品现在正在文化展览中展出。
3. 出于策略、委婉、礼貌等不提出动作的执行者时。Yu are said t be active recently.据说你最近很活跃。It is reprted that they will cme t ur city fr a visit.据报道,他们要来我们城市访问。
(1) 双宾动词的被动结构 例:He gave her sme mney. She was given sme mney. Sme mney was given t her.
带有双宾语的主动句,变被动句时,一般把“人”提前作主语;将“物”提前则要在“人”的前面加 t 或 fr。
带复合宾语的动词变被动语态时, 一般将主动结构中的宾语变为被动结构中的主语, 而将宾语补足语保留不动(这时的宾语补足语为主语补足语)。
(2) 带复合宾语的动词的被动结构 例:His father called him Jack.
He was called Jack by his father.
(3)“it + be + 过去分词 + 从句”式的被动结构 常见的结构有:
It is knwn that ... It is suggested that ... It is believed that ... It is reprted that ... It is said that ... It is hped that ...

1. 某些连系动词,如 feel, lk, prve, smell, sund, taste 等。
例:It can’t mve. The dr wn’t shut.
2. 某些与 can’t, wn’t 等连用的不及物动词,如mve, lck, shut, pen等。
例:My new pen writes well. The clth desn’t wash easily.
3. 某些可与well, easily 等副词连用的不及物动词,如read, write, wash 等。
② 非谓语动词的某些主动形式表示被动意义 例:The questin is difficult t answer. Vlleyball is very interesting t watch.
在“be + 形容词+ 不定式”结构中,不定式表示的动作与句子主语之间是逻辑上的动宾关系时,用主动形式表示被动意义。常见形容词有:cheap, easy, cmfrtable, difficult, hard, light, heavy, expensive, pleasant, interesting, fit 等
例:The film is well wrth seeing. The plicy is partly t blame fr causing the wrst unemplyment in Eurpe.
在 be wrth ding 和 be t blame 结构中,动词-ing 形式或动词不定式用主动形式表示被动意义。
当want, need, require, deserve 表示“需要”或“值得”时,其宾语可用动词-ing 形式的主动形式表示被动意义。
