这里考查的是一般现在时跟现在完成时的区别
A是一般现在时,一般现在时的定义是,表示习惯性、通常性、有规律性的状态或者动作的一种时间状态.一般现在时强调的是经常发生或者习惯发生.
B是现在完成时,现在完成时的定义为过去发生并且已经完成的动作对现在造成影响或结果,过去某一时间开始并一直持续到现在的动作或状态.现在完成时强调的是过去已经发生并对现在造成影响,而且持续到现在.
根据句意,她一个人悲伤的坐在教室里,应该是过去发生的某件事情导致是结果,并且一直持续到现在,答案选B

则么可能是A
选B
has代表现在完成时

A
happen发生,没有被动语态。
A选项意思是:她发生了什么事?

我说那个题目是不是打错了 look有问题啊
