----is that the student cant stand so many exams.
A what she worries
B what worries her

B
worry物做主语时是及物动词,
而人做主语时为不及物动词,所以A应该为;
What she worries about ....

B worry是动词
只能是what worries her
或what she is worried about

worry 是及物动词，所以应该是 事物worry人 ，而不是 人worry 事物 啊。
所以是后面的这一整件事作前面的半句主语。选B。

b 使她担心的是.... what 引导了主语从句
一般what用在名词性从句中
=the thing that
what 做主语
再如:
what moved me deeply was ....
what surprised us is that she should treat him like that
令我们吃惊的是...
