问题描述:
she think it difficult to learn 这句话是什么句型?什么结构?
能换成she thinks it's difficult to learn 它们什么区别?.
答
不定式作宾语的复合结构
语法点:
【1】
不定式作宾语的复合结构就是不定式作句子宾语的补足语
当谓语是consider、find、think时,to be 可以省略
eg.I think it (to be)necessary for him to go there at once.
此句中
it 【宾语(形式宾语,真正的宾语是不定式 to learn 】
to learn 【这个不定式就是 it 的补足语了,构成了复合宾语】
she thinks(that) it's difficult to learn 宾语从句
it's difficult to learn 是think的宾语
