关于宾语补足语的问题
I don't think it right for them to do so.
I think it is necessary for the students to own mobile phones.
以上两句句子,为什么前一句it后没有is
而后一句却有is呢?
那这两句可以改为这种形式嚒:
I don't think it is right for them to do so.
I think it necessary for the students to own mobile phones.
第一个是i think it +adj.+to do sth.的用法
第二个是宾语从句 it是宾语里面的形式主语
I think ( to own mobile phones is necessary for the students) .
避免头重脚轻才加it
