University is Students’ fight goal, entering the university means the promising future for students. In most university campus, the scenery is very beautiful, some campus are even the hot tourist sites. Like Cambridge and Oxford, many people go there to have a look at the beautiful sites. Campus seem to be the open to tourist sites, I think it is not good to be open.
大學是學生奮鬥的目標，進入大學對學生來說意味着有一個光明的未來。在大部分大學校園裏，風景是很漂亮的，一些大學校園甚至成爲熱門的旅遊景點。比如劍橋和牛津，很多人去那裏只爲看一眼美麗的風景。大學校園似乎對旅客開放，我覺得開放是不好的。 
On the one hand, when tourists come, there will be a lot of rubbish. We always hear about the news that in the tourist sites, many rubbish are left, which makes the sites polluted. University campus are the places for students to study, the places should be clean and quiet. 
一方面，當遊客來到校園，就會帶來很多的垃圾。我們總是聽到這樣的新聞，在一些旅遊景點，留下了很多垃圾，使得景點受到了污染。大學校園是給學生學習的地方，應該是乾淨和安靜的。
On the other hand, when campus is open to the tourists, it means anyone can go into the school, it will be not safe to students. Some bad people will pretend to be the tourists and go into the campus to steal things. Some students will fight against the bad guys and will get hurt. Opening the campus gives the bad guys the chance to make crime.
另一方面，當大學校園對遊客開放，意味着任何人都可以進入校園，對於學生來說很不安全。一些不懷好意的人會假裝成遊客，進入到校園來偷竊。一些學生會和歹徒搏鬥，傷到自己。開放校園給壞人帶來了犯罪的機會。
University campus should be clean and quiet for students to learn knowledge. Students also need a safe environment. So it is not good to open the university for tourists.
大學校園應該是乾淨和安靜的，有利於學生學習知識。學生也需要一個安全的環境。所以大學校園對旅客開放是不好的。
