同学,这个题最好应该填BUT~~~
从逻辑上来讲,except 是正确的.首先给你个简单的例子:I love nothing except ice-cream.我觉得你的智商可以理解这里为什么填except.excpet: not include ,即不包含.后面可以加各种结构~当然也可以加that的从句.其实那个逗号要不要都是可以的.
知道了except 是正确的,当然你就知道为什么besides不对啦~
In this sentence, it means that the information that he works in an office is the only thing i know about him, so I have already known this, u cant say the information is in the range of "nothing" by using besides.
