✓ What did you do with the old car? 你如何处理你的旧车了？

[✌上述疑问句是对do sth with ...中sth的提问，所以用what，不能用how]

用法主语部分有do的各种形式时，作表语的不定式可省略to。如：What we should do now is (to) make a plan. 我们现在要做的事就是制订一个计划。但注意下句的to表示目的，不能省略：He does whatever he can to help her. 他竭尽所能去帮助她。

常犯错误

“他为我们做了很多。”译为：

✗ He did a lot to us.

✓ He did a lot for us.

[✌do sth to sb表示“伤害某人”，而do sth for sb才是“帮助某人”]

谚语What's done cannot be undone. 事已定局，无法挽回（或：木已成舟）。
