do with 和deal with区别

1. do with “对待/处理”，用what提问和连接。
如：I don't know what to do with the problem.
=I don't know what I should do with the problem.

2. deal with “对待/处理/与...做生意/提及，谈及”

如：He ofen deals with foreingers. 他经常和外国人做生意。
The new plan was dealt with at the meeting. 这个新计划在会议上被提到了。

如果解释为“对待/处理”时，它一般用how提问或连接。
如：I don't know how to deal with the problem.
=I don't know how I should deal with the problem.

what ... do with
how ...deal with

前者一般与What连用 而后者一般与How连用
