　A. The color of the dog.
　B. The price of the dog.
　C. Whether the dog will fit the environment.
　D. Whether the dog will get along with the other pets in the house.
答案：C细节题。根据文章的内容，买狗的时候并没有提到要考虑狗的颜色、狗的价格，以及狗能否和家中的其他宠物很好的相处。但是提到了要考虑狗能否适应周围的环境。“whether the dog is likely to be happy in the surroundings you can provide.”

答案：C细节题。demanding：要求高的，费力的。作者认为狗是比猫费心的宠物，因为猫喜欢我们的房子，只要住的地方安全，它就会非常的满足。而狗则不同，你必需在它很小的时候花很多的精力去训练它，如果你不住在农村，没有机会让狗自由活动的话，你还必须给它这样的机会。而且你最好在三个月以前就买回来，这样有利于和主人培养感情。可见狗是多么的费心。

Passage 4 
Movies are the most popular form of entertainment for millions of Americans. They go to the movies to escape their normal everyday existence and to experience a life more exciting than their own. They may choose to see a particular film because they like the actors or because they have heard the film has a good story. But the main reason why people go to the movies is to escape. Sitting in a dark theater, watching the images on the screen, they enter another world that is real to them. They become involved in the lives of the characters in the movie, and for two hours, they forget all about their own problems. They are in a dream world where things often appear to be more romantic（浪漫的）and beautiful than in real life.

The biggest “dream factories” are in Hollywood, the capital of the film industry. Each year, Hollywood studios make hundreds of movies that are shown all over the world. American movies are popular because they tell stories and they are well-made. They provide the public with heroes who do things the average person would like to do but often can’t. People have to cope with many problems and much trouble in real life, so they feel encouraged when they see the “good guys” win in the movies.
