An increasing number of people are moving and living in big cities. Why is this case？ Is it a positive or negative trend？ （2010年1月23日 G类） 该题有两个问题，很多考生在作答时忽视了第一问，只回答第二问，抑或是把第一问和该现象积极的一面混为一谈，如：

　　On the one hand， living in big cities brings about a considerable number of advantages， which is also why people move to big cities. Initially， it is undeniable that work conditions in big cities are usually better that those in countries and small cities. With more work opportunities and a higher level of salary， people in other places， especially the young， are inclined to move to big cities. Subsequently， not only does living in big cities offer people better work conditions， but also it affords dwellers with facilities of higher quality. These facilities， such as the premium hospitals and education resources， are extremely attractive to countryside people and those in small cities. （考生答卷）

　　该现象的原因应从大城市移民的角度考虑，如可以享受更好的生活设施，教育资源和就业机会等。而其积极的一面应从城市居民或管理者的角度考虑，如大量的“移民”给城市带来了更多的劳动力和税收。

　　遇到此类考题，考生可以将全文分为四个段落，除去开头和结尾段，主体两个段落分别回答一个问题，即第二段回答产生该现象的“原因”，第三段选取积极或消极任何一面展开论述。
