Question

I think it important for us to learn English well 是否正确

I think it is important for us to learn English well .这个句子是否也正确，为什么呢？

Answer 1

、I 是整个句子的主语，think作谓语，it作形式宾语，important作宾语补足语，for us表对 象， to learn English well 是真正的宾语。
二、如果句子换做I think it is important for us to learn English well.
I是句子的主语，think作谓语，think之后是一个由that引导的宾语从句，其中that可以省略。 it is important for us to learn English well.是一个宾语从句。在宾语从句中，it作主语，is是系动词，important作表语，for us 表对象，to learn English well是真正的主语。
