Some people are quite in favor of the campus’ opening to tourists while others are opposed to it. The opening of campus will stimulate the tourist industry, but the easier access to campus will lead to some ac cidents or safety problems which will interfere in students’ life. In my opinion, campuses can be open to tourists once a week, say, on Saturday or Sunday. This suggestion, I believe, is quite workable because it could kill two birds with one stone. For one thing, campuses could attract many tourists on weekends, thus boosting the tourism.

Some people are quite in favor of the campus’ opening to tourists while others are opposed to it. The opening of campus will stimulate the tourist industry, but the easier access to campus will lead to some accidents or safety problems which will interfere in s tudents’ life. In my opinion, campuses can be open to tourists once a week, say, on Saturday or Sunday. This suggestion, I believe, is quite workable because it could kill two birds with one stone. For one thing, campuses could attract many tourists on weekends, thus boosting the tourism. For another, restricted opening of campus will beneficially narrow the gap between campuses and the outside world. Furthermore, this will also attract more public attention and build a great reputation for the university. Unit Two 4.翻译(十选五,每题3分,共15分) 1). 美国文化的一个特点就是尊重自我奋斗者,即通过自身努力成功的人。 2). 他想帮助所有受伤的人,不管他们是为了哪一方而战。 3). 我被他们相互矛盾的意见搞糊涂了,不知如何去做才是。
