I would do whatever I can to help you.
You just do what you want.
這兩個句子是不是省略了什么? 是不是 whatever I want to do, 畢竟要加個 do 才能說得通啊,第二個句子中是不是應該改為what you want to do, 應該是 do sth 呀,這是一種省略句還是什么其它的?
I would do whatever I can to help you. 可視為在can后省略了do(但這個do通常是省略的)。
You just do what you want. 可視為want 后省略了 to do(但這個to do通常是省略的)。
