英语问题,求解释present perfect 和 present perfect continuous.
例；
he has been crying in the bathroom.
he has been cry because he looks unhappy.
这里例子对吗,求解释为什么一个用crying 一个用 cry.
像这题she has been (stand) outside for 2 hous.是要用stand 还是 standing ?

1.He has been cry because he looks unhappy.他（过去）哭过因为他看起来不高兴
have been+动词过去分词为现在完成时,表示过去（曾经）做过某事
2.He has been crying in the bathroom.他在浴室哭到现在.
have been+doing 为现在完成进行时表示某一动作从过去发生时一直持续到现在,并且有可能继续持续下去
你滴,明白?
