have done,是的
再问：可以简单的讲解一下现在完成时吗？对于英语中的时态我实在是有些迷糊！
再答： do,dose,is,are出现表示事情还没发生或者正在发生，称为一般现在时，可表现在也可表将来的一种状态； did,were,was,had出现时，表示事情已经过去或已经完成，表示过去的状态； have done表示这件事已完成，其影响从过去影响到现在并且对将来依然会产生影响，表示现在完成时； had done表示这个动作已经完成并且其影响已经停止，表示过去完成的状态。

I have already had a crash 这句是现在完成时吗? I have already had found 用had,a tea I,already,have,cup,of造句英语did you have a crash?可以说成have you had a crash? 谁知道 I have a crash on you! I have already had lunch 是什么结构 I an have some had 改成现在完成时 I have already seen it.不是过去的事情吗?怎么会是现在完成时? “I know you have already had a boy friend”翻译成中文怎么说? have already had mine I don't mind because I have already had I have already had lunch.--为什么在already前要加"have",下面不行吗?
