不知道或没有必要说明动作的执行者是谁 it s wassaid believed reported that it sreportedthataboutthreehundredpeoplewerekilledinthisearthquake 据报道 这次地震中大约有三百人死亡 2 强调动作的承受者 这时应用by短语 thecupwasbrokenbydavid 3 作客观说明时

指物的宾语叫直接宾语 指人的宾语叫间接宾语 常见的接双宾语的动词有 to pass give teach show bring handfor make buy draw sing get 以 人 当主语时 变法和一般的变法一样 以 物 当主语时 在保留的间接宾语前必须加to或for keep make三类的动词常常有宾语补足语 在被动语态中 宾语补足语位置不变 wekeepfoodfreshinthefridge 主谓宾宾补 foodiskeptfreshinthefridge isawhimgointotheofficebuilding hewasseentogointotheofficebuilding 2 含有宾语补足语的句子的被动语态 不及物动词没有宾语 因此没有被动语态 但有的不及物动词后面加上介词及其他一些词类构成短语动词之后 其作用相当于及物动词 可以接宾语 因而也可以变为被动语态 在变成被动语态时 不能去掉构成短语动词的介词或副词 theytakegoodcareofmychild mychildistakengoodcareof iturnedofftheradio theradiowasturnedoff byme 3 含有短语的主动语态变被动语态 下列这些短语本身即是被动语态的形式 不需再加

make let look watch see notice 这些词在主动句中 其后的动词不定式不加to 但变被动句时必须加to 1 isawhimplaybasketballlastsunday he wasseen toplaybasketballlastsunday 2 weheardthemsingintheclassroom they washeard tosingintheclassroom 4 感官动词和使役动词的被动语态 1 当主动结构中的宾语是反身代词和相互代词时 不能改为被动语态 weoftenhelpeachother 我们常常互相帮助 2 当谓语是表状态的及物动词时 如have like takeplace belongto 如 iliketheseflowers 我喜欢这些花 iwillhaveameeting
