New York, London and Paris. 答案：DCDDA解析：从短文第一段，我们知道在大城市能够参观不同的博物馆，看各种各样的喜剧和电影以及买来自全世界的东西。选D。短文第二段原句：It is expensive to live there, and there are too many people in some places of big cities.  我们知道在大城市不容易居住。所以C不正确。短文最后一段最后一句原话说： Before move to a big city, they should think about the problem of living there.  因此作者认为，在搬去大城市之前，他们应该考虑住在那里的一些问题。选D。综合短文内容，我们知道作者没有提及D人会变得很脏。短文在讨论大城市的好处和坏处，因此选A大城市。
