要初2能看懂得 问题what__you__(do)after that?-----I________(repair)something.怎么填,为什么,什么时候用be+doing..什么时候用do..do(好比what do you do )为什么不用what is you doing?

即使用现在时，也是用what are you doing?而不是用what is you doing?其次由于它是问“你在那以后做了什么”，不能够现在时，应该用：

What did you do after that?
I repaired something.

be+doing是指现在时，例如：
I'm repairing a car.我正在修理一辆车（强调正在进行）
I'm swimming now.我现在正在游泳。（强调正在进行）

do..do实指现在时，例如：
I swims everyday.我每天都游泳。（强调平时会做，而不是正在进行）

what<did> you <do> after that?-----I <repaired> something.
问句意思:在那之后你做了什么?明显,需用过去时.
进行时用be +动词ing形式.
一般现在时用do(第一人称)或does(第二人称)
what's you doing是问"你现在在做什么",根据这道题的题意,从"after that"(在那之后)我们可以看出,显然是对过去的事进行发问.故用过去时.
希望满意!:)

YOU 当然不可以用 IS
BE+DOING强调动作正在发生,DO...DO则是动作的反复性
