What has happened\happens to her?选择
Susan stays alone in the classroom and looks sad.
__________to her?
A.What happens
B.What has happened
A和B的区别是什么?为什么选B?
根据前文我们知道句子的时态是一般现在时,根据前文Susan呆呆的呆在教室独自伤心,那我们知道应该是在她身上发生了某些事情,而这些事情对她是有影响的(使得她伤心,发呆),所以用完成时,表示过去的动作对现在造成影响.A的话就是说现在她发生了什么事情.(说得比较啰嗦,不知道看懂了吗)
B是现在完成时,这个时态表示过去发生的事对现在所造成的结果,她发生了什么使她看上去如此伤心呢?伤心是这个事件对她所造成的影响,所以选B
A是一般现在时,表示经常性动作
B是现在完成时,表示过去发生,但强调对现在的影响。
选项B表示她发生过什么事使她看上去伤心
A是现在完成时B是过去完成时。题意为她身上发生了什么。“发生了”是已经过去了的
