That's exactly ( )I feel right now.填what还是how? That's just____I feel.这道题是填what 还是填how That's just____I feel.这道题是填what 还是填how 答案是how,可是为什么不能填what呢? That's exactly what I what.为什么用exactly啊? that's just what I want right now that's exactly what i had in That's exactly what I expected. No words can express how grateful i feel now. Right? 常常有个问题 what exactly are you doing here?that's exactly what i That's exactly what I'm talking about 是什么从句 that's exactly what i had in mind that's exactly what i want.这里的exactly副词修饰什么?
