Question

英文问题求解。请问下面的解释都对吗？

不定式作逻辑主语
如：（It） is very kind of you （to help me.）
形式主语 真正的主语
还原：To help me is very kind of you. (头重脚轻)

从句作逻辑主语
（It） is extremely obvious （that she has been lying about her identity.）
形式主语 真正的主语
还原：That she has been lying about her identity is extremely obvious. (头重脚轻)

动名词短语作逻辑主语
（It) is no good (reading in dim light.)
形式主语 真正的主语
还原：Reading in dim light is no good. (头重脚轻)

Answer 1

正确，英语的句子是后重型的句子，为了避免头重脚轻，通常用it做形式主语或形式宾语，而把真正的主语或真正的宾语放在句末。

Answer 2

没问题的
