先谈社会话题：

　　负面的话题无非要涉及解决的问题，正面话题就是展望未来，现在送大家一些在考研和四六级中正负面话题都能用的表达：

　　The general public is supposed to enhance their awareness that

　　大众需要提升对于…的意识是，

　　? In view of the complexity of such a topic, we must treat it socially, economically and culturally.

　　考虑到话题的复杂性，我们必须从社会，经济和文化角度来对待这个话题。

　　? In a sense, it is not why sth. exists in today's world but what we should do to cope with it.

　　总之，不是讨论为什么在今天的世界会存在这种话题，而在于我们应该怎么去应对他。

　　文章最后一定能用到的表达：

　　In view of the importance and the complexity of such a positive/negative phenomenon, we must treat it socially, economically and culturally and maintain it the very force that has driven our society/或 life forward. Only in a reasonable, prosperous and healthy atmosphere can we hope to witness the ideal scene in which people can enjoy their life to the uttermost./或in which student can enjoy their study to the uttermost.

　　具体的一个话题：名人代言(celebrity endorsement)

　　With celebrity endorsement increasingly used by companies and manufactures in our society to promote their products, we, as customers, should always keep a clear mind and make sensible decisions. Meanwhile, it is also our government's responsibility to make laws and regulations for celebrity endorsement to ensure the rights of customers and create a safe and sound environment for the development of advertising business.

　　特别警惕，四六级还可以出一些应用文作为考察的对象，这里附上一篇欢迎辞;
