我认为你的文章总体还是不错的,但也有一些小问题,具体如下：
1.“However,on the university side,the administrators of the campus has different considerations about they should open their campus to tourists.”这句话我认为欠妥,可以改为“However,on the university side,the administrators of the campus have different ideas as to whether they should open their campus to tourists.”
2.第二段里面的seems to改为seems as
3.第二段make a good choice to最好改为动词,因为这种结构没见过,我指的是后面这个介词,除非你将to改为of
4.第二段too much tourists改为too many tourists
5.第二段最后一句里面的maybe改为may
6.我认为第三段应该和第四段合并.而且第四段句意不够明确.我认为应改为：However,school authority should limit the amount of tourists so that life of students and teachers in school won't be bothered too much.
