” 另外，我觉得住在校外除自由以外，还能省钱，很安静，很合也很舒适。

I think living off campus has many benefits. My friend who lives off campus told me, "compared to living on campus, living off campus is very inexpensive." Additionally, I think living off campus is, in addition to being more free, more cost-effective and quiet. The best benefit of living off campus is clean bathrooms. But I live on campus. Although living off campus has many benefits, it has more disadvantages. I think one drawback of living off campus is that it's very far from school. My friend has to take a bus to get to class! I can walk. Living of campus is troublesome because 1) it's not necessarily inexpensive, 2) it's hard to find a good apartment, 3) it's possible you could have a roommate with no money -- in that case, how can you rent an apartment? I don't have to worry because my job makes my dorm expenses very cheap.

我朋友得坐公共汽车去来上课，因为他住在校外！

因为你在学校里，你的朋友朝向你的方向来上课，所以是“来”而不是“去”。

而我能走路。

住在校外很麻烦，因为第一，不见得便宜，第二，很难找到好的公寓，第三，你可能会有没钱的室友----那是这样的话还怎么租公寓的呢？
