第一个是对的。三四句语法错误。“你怎么能这样做?”说明事情已经发生过了,所以现在提问用过去时,过去/当时你怎么能够这样做?第二句是现在时,除非你发问之前事情刚刚发生,否则都必须用过去时提问。
What do you mean by this?
What do you mean by doing that?
What do you mean since you did that?
你这样做是为了什么?
What is that you are acted as like this for?
(只是为了乐于助人)
(Only for being eager to help people)
不图什么?
What do not seek?
你应该告诉你的父母这么做是有原因的
You should tell your parents to do for a reason
Why did you.
后面接要说的话
你为何要这么做:Why did you do that?或者 Why did you do it?
What do you think have made this happen?
make sth happen
使某事发生
happen 英[ˈhæpən] 美[ˈhæpən]
vi. 发生; 出现; 碰巧; 偶然遇到;
[网络] 发生,碰巧; 出; (偶然)发生;
[例句]Just when this will happen is anyone's guess.
谁也说不准这事什么时候会发生。
[其他] 第三人称单数:happens 现在分词:happening 过去式:happened过去分词:happened 形近词: happed rappen hippen
