Key to Model Test (7) Band Four Part I. Writing Sample Writing: Should the University Campus be Open to Tourists? Thanks to the rapid development of our modern society, great changes have taken place on the campus. On university campus, especially in some famous ones, such as Peking University and Tsinghua University, tourists are always seen looking around everywhere. When it comes to the problem, people’s opinions differ. Some folks harbor the idea that it not only makes some profit from the tourism, but also promotes the fame of the university. But others hold the different belief that the university campus should not be open to tourists. Sometimes they get into teaching buildings, libraries and so on, thus make noises and throw rubbish everywhere. Besides that, some tourists trample grass to take photos, and sculpture on trees to leave words. These will affect the environment of the campus badly. In my opinion, university campus should be open to tourists. As more tourists come to visit universities, these universities can widen their influence. That is because it is a dream for many Chinese parents and young ambitious students. But at the same time, the university should try to set up some rules to prevent tourists from disturbing the normal operations. Part II. Reading Comprehension (Skimming and Scanning) 1.
