用like还是as? He made it clear that he do not want to go with her,___her father did 2 days ago.

as

as like

1a．前者是个连词，后者是个介词，混淆不得。

Paul behaved like a child．保罗的举止像个小孩。（句子没有省略）

Let me speak to you like a father．让我像你父亲那样对你说说。（= I am not your father but I am speaking to you in the way your father might）
Auntie Lucy took care of the wounded soldier as her own son．
露茜老大娘像照料她自己的儿子一样照料这个伤兵。
（＝…as she would take care of her own son）
Auntie Lucy took care of the wounded soldier like her own son．露茜老大娘像照料她自己的儿子一样照料这个伤兵。
（句子没有省略）
Tomorrow，we'll discuss the question again as yesterday．明天也像昨天那样我们仍继续讨论这个问题。（=…as we did yesterday，所以这里的yesterday是个副词）

1b．遇到如下情况，可以把前者当作介词那样来使用（注：有的英语词典干脆把as列为介词来编）：第一，用作“作为”讲的时候；第二，用来举例，比如用来代替for example的时候；第三，用来引导某些动词，如：look up
