绿色校园这个提纲应该先定义一下什么是绿色校园，然后再说一下为什么重要，最后再说我们应该怎么做。他非得给这样的提纲，我们只有按照这个提纲去写了。绿色校园的重要性当然和气侯变暖这样的事情联系起来，我们应该用节能的东西，不应该浪费，这个对维持人类的生存，可持续发展，以及防止气侯进一步变暖都是有重要意义的。　　什么是绿色校园，就是一个没有浪费的校园，一个节能的校园。然后我们应该怎么做？也就是从小事做起，应该节约粮食，节约纸张，甚至包括我们的服装、鞋子、生活用品节约。对于一些造成污染的可回收的物品，我们应该去协助做回收工作，比如说电池，往往是扔在垃圾里面，我们应该改变一些行为。这个总体上来说，是跟以前的题目相比，不过以前的四级题也挺难的，比如博物馆免费开放。好象四级比较难，六级比较容易。　　优秀范文：　　The universitys branch campuses in suburban areas　　In recent years more and more universities have built up their branch campuses in suburban areas. Now it is very difficult to find a university without a branch campus. Maybe no one can tell clearly when the first branch campus came out。　　But the reasons behind this phenomenon are obvious. Among these reasons, the enrollment expansion of universities plays a very vital role. As more and more freshmen are remitted to universities, the original facilities, including classrooms, apartments, dining houses, laboratories and the like, are not enough any more. Whats more, the land in the suburb is relatively low in price, which is affordable for most universities. Besides, the quiet environment in suburban areas is more suitable for students to study。　　As a college student, I think, it is necessary and beneficial for many universities to build up a branch campus. However the building of branch campuses brings some problems. For one thing, the students in some branch campuses cannot enjoy good enough facilities and the teachers due to limited resources. For another it leads to less direct communications among teachers and students. Therefore the university should take a full account before it decides to build up a branch campus。
