the boy made the baby cry 改成被动语态

问题描述:

the boy made the baby cry 改成被动语态

The baby was made to cry (by the boy).这是不定式的被动语态 不定式的被动语态的结果是 to be done 可是你改成 be to done能不能解释下呢?是这样的,使役动词(就是让谁做什么的动词,如:let/make/get/have等)后原本跟不带to的动词不定式,即动词原形,在变为被动时,必须将to显示出来,变成:be done to do主动时:made sb. cry(其实是:省略了to的动词不定式 to cry)被动时:was made to cry(to不能省略)可是不定时的被动语态的结构是to be done 啊to 放前 be动词放中done 放后这里是谓语变被动,不是动词不定式变被动啊made(过去时)是谓语,将谓语变被动,不就是was made(was是过去时,made是过去分词)后面的动词不定式保持不变(只是将原来主动语态下省略的to显示出来就行)oki see thank you for your answer 那你能举个不定式的被动语态的句子吗?The traffic pressure will be relieved by a bridge to be built.交通压力将被缓和,通过将建一座桥(桥是被建的,还没建,用动词不定式的被动语态)
