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?.
she thinks it's difficult to learn
“think+宾语从句”表示...认为...
she think it difficult to learn
think+it+adj. / noun.+(for sb)to do sth, 表示“认为某人做某事怎么样”, it 是形式宾语,(for sb)to do sth 即不定式的复合结构为真正的宾语
表达的意思是一样的~
1 she(主语) thinks(谓语) it(形式宾语) difficult (宾语补足语)to learn --- (真正宾语)
- - .是简单句
2 she (主语)thinks (谓语)(that)(宾语从句连接词)it(形式主语) is (谓语)difficult (表语)to learn (真正主语)- -
- -是宾语从句
第一句话:
1.注意三单形式;
2.动词不定式做宾语,it是形式宾语,to learn是真正宾语 ,这种结构必须有宾补如difficult.
第二句话:
1.She thinks可以理解为插入语,可省略;
2宾语从句的动宾结构,it's difficult to learn 这个整体做句子的宾语,而to learn 在小句子(it's difficultto learn)里做真正主语,it为小句子的形式主语;
3.it's+adj+to do是固定结构;
不能,因为此时it做形式宾语,she think it is good.就可以
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
