5个回答

  • 我是第三名回答者,刚才打错了,应该省略之后是 It is(be) done in this way.不能说 It is be done in this way.所以说加上had to 之后,也不能说 It is had to be done in this way.

    A 选项,it 作为主语,只物,必须被动,所以不能用do.而且,两个动词不能同时存在.

    B选项,is 和 be 都是动词.一句话中同一个单元不能有两个动词.

    C正确.

    D选项,不能用主动,所以不能是do.

    第二名回答者,had to 可以用于被动,很多时候had to 都用于被动语气.

    第四名,如果你想说been的话,可以是 It has been done,或者是 It had been done.不能说 It is been done.
