10、妹画的吗? 二、被动语态的用法: 1. 不知道谁是动作的执行者,或没有必要指出谁是动作的执行者。 e.g.Englishisspoken all over the world.全世界都在说英语。 2. 须要突出或强调动作的承受者。 e.g.Thisdictionaryis used by most students. 这本字典是大多数学生在用的。 三、主动语态变被动语态应留意的问题 1. 有些短语动词相当于及物动词,变为被动句时介词或副词不能去掉。 They putoffthe meeting because of theweather.

11、se of theweather. 会议因天气的原因被推迟了。 2. 含有双宾语的主动句变为被动句时,通常把指“人”的间接宾语变为主语,指“物”的干脆宾语保留不变;假如把指物”的干脆宾语变为主语,则在间接宾语前加to或for。 My auntgaveme an e-dictionary yesterday. I was givenane-dictionary yesterday. Ane-dictionarywasgiven to me yesterday. 3. 主动句中感官动词see/hear/watch/feel等和使役动词make/let/have等后跟省略to 的动词不定式,变为被动
12、语态时应加上不定式符号to。 I saw aheavymanenter the house. A heavy manwasseento enter the house. 4. 系动词、不及物动词或某些短语动词(happen, takeplace,come true, fall asleep)没有被动语态。 What happenedtoMr.Brown? 布朗先生发生了什么事? .
