As China opens its door, it is a dream for many Chinese students to study abroad. They want to learn about the outside world. It"s true that studying abroad can help students develop themselves. Their foreign language skills will be improved and it may be easier to find jobs． But there are problems that should be considered．Language is the first．Students must spend a lot of time 1earning another language． Students must also leam to live without parents’care and deal with all kinds of things they haven"t had to do before，like looking after themselves．There are reports about Chinese students abroad running into an ocean of difficulties and giving up finally．When they have to take care of themselves，it is hard for students to study well． Finally，studying abroad brings a heavy burden(负担) to most Chinese parents，the cost of studying abroad is very high .But is it worth it? We know that there are many famous people who have succeeded in great things through their hard work in China．Liu Xiang is a good example．Once an American teacher invited him there，but he refused． He kept training hard with his Chinese teacher. He surprised the world when he won a gold medal at the Athens Olympic Games . So when you wonder which country is better to study in，think again.

8 Some people think that as more and more people have televisions in their homes, fewer and fewer people will buy books and newspapers. Why read an article in the newspaper, when the TV news can bring you the information in a few minutes and with pictures? Why read the life story of a famous man, when a short television program can tell you all that you want to know? Television has not killed reading, however. Today, newspapers sell in very large numbers. And books of every kind are sold more than ever before. Books are still a cheap way to get information and enjoyment. Although some books with hard covers are expensive, many books are printed today as paperbooks (平装本), which are quite cheap. A paperback collection of short stories, for example, is always cheaper than an evening at the cinema or the theater, and you can keep a book for ever and read it many times. Books are a wonderful provider of knowledge and pleasure and some types of books should be in every home. Every home should have a good dictionary. A good encyclopedia (百科全书), though expensive, is useful, too, because you can find information on any subject. Besides, you can have such books as history books, science textbooks, cookbooks, and collections of stories and poems. Then from time to time you can take a book of poems off your shelves and read the thoughts and feelings of your favorite poets. 小题1:It can be inferred from the passage that ____. A．Fewer and fewer people will buy books. B．A good dictionary should be kept in every home. C．Books with hard covers sell better than paperbooks. D．More people like TV programs about famous men. 小题2:What does the sentence “Television has not killed reading, however.” underlined in the second paragraph suggest? A．People only need reading, though. B．Reading is still necessary today. C．Reading is more fun than television. D．Watching television doesn’t help reading. 小题3:What can we learn from the passage? A．TV programs are a chief provider of knowledge. B．Cinemas are the best choice in getting information. C．Reading is cheap way of learning and having fun. D．Newspapers are an expensive way to enjoy oneself.
