在英文里，動語不能直接做主語，要變為動名詞或者不定式短語。
例如：
Working with him is interesting.
To learn engish with peter is fan.
動名詞用于做有經驗的事情。
不定式用于沒有實現的事情，例如計劃，設想等。

如果不定式短語做為主語過長，可以虛的主語，it來代替，不定式短語放在句尾。
例如：
It it my plan to study aboard with very good friend of mine whose call jone.

中文里可以用句子做主語，而英文里不可以，要將句子變為名詞從句。
句子前面加一個連詞that，構成名詞從句。
例如：
That she loves me is ture.
That he doesn't agree with me makes me angry.
It makes me angry that he doesn't agree with me.
