As I write this, I have half an eye on an old James Bond film that is showing on my computer. But this is a story about how I stopped watching TV and began reading again for pleasure, after ten years in which I hardly turned a page.
I suppose I was an enthusiastic reader of "literature" between the ages of nine and fourteen. I had enough time to be White Fang, Robinson Crusoe, and Bilbo Baggins and Jeeves. Of course there was room in the schoolboy's imagination for some real historical figures: Scott of the Antarctic, all of the Vikings, and Benjamin Franklin were good friends of mine.
Then, in adolescence, I began a long search for strange and radical (激进的) ideas. I wanted to challenge my elders and betters, and shock my fellow students with amazing points of view. Of course, the only place to look was in books. I hunted out the longest titles and the authors with the funniest names; I searched the library for completely unread books. Then I found one which became my bible for the whole of 1982, it had a title composed of eleven long words and an author whose name I didn't know how to pronounce. It was really thick and looked dead serious. Even better, it put forward a whole world-view that would take days to explain. Perfect. I took it out of the library three times, proud to see the date-stamps lined up on the empty library insert.
Later, I went to university. Expecting to spend long evenings in learned discussion with clever people, I started reading philosophy. For some reason I never found the deep-thinking intellectuals I hoped to meet. Anyway, I was ready to impress with my profound (深奥的) knowledge of post-structuralism, existentialism and situationism. These things are usually explained in rather short books, but they take a long time to get through. They were the end of my youthful reading.
Working life was hard to get used to after so much theory. It was the end of books for me. There didn't seem to be much in books that would actually get things done. To do things you had to answer the telephone and work a computer. You had to travel about and speak to people who weren't at all interested in philosophy. I didn't stop reading, you can't avoid that. I read all day. But no books came my way, only manuals (操作手册) and contracts and documents. Maybe most people satisfy their need for stories and ideas with TV and, to tell the truth, it was all I needed for ten years. In those days I only had a book "on the go" for the duration of aeroplane flights. At first I would come home and watch TV over dinner. Then, I moved the TV so I could watch it from bed. I even got a switch so I could turn it off without getting out of bed. Then, one fateful day, my TV broke and my landlady took it away.
My new TV is an extra circuit board (电路板) inside my computer. It's on a desk in front of a working chair and I can't see it from the bed. I still use it for the weather forecasts and it's nice to have it on while I'm typing this… but what to do last thing at night? Well, have another go with books.
Now, I just like books. I have a pile of nice ones by my bed and I'm reading about six at the same time. I don't want to be any of the characters. I don't care if a thousand people have already read them. I don't have to search through libraries. There are books everywhere and all of them have something to read in them. I have the strange feeling that they've been there all along, waiting for me to pick them up.
【小题1】The writer enjoyed reading “literature” between the ages of nine and fourteen because ________.

As I was leaving to meet Lynne，my roommate told me that I’d better take some money，but I didn’t listen to him. I thought that Lynne would pay because she had invited me.
I arrived at the restaurant exactly on time. I’d been told that Americans expect you to be on time. Lynne and I sat at a table in the corner of the restaurant and a waitress came and took our order. The dinner was a great success. I talked a lot about Saudi Arabia and Lynne told me all about herself. After two hours the waitress finally came and asked if we wanted one check or two. Lynne said two. We went to the cashier and Lynne paid her check. I was embarrassed (尴尬) when the cashier gave me my bill. I had no money to pay for my meal. Then I had an idea. I pretended to look for something in my pockets and said，“Oh！I forgot my money! Can I call my roommate，please？” The cashier showed me where the phone was and I quickly called my roommate.
In a few minutes he arrived with some money，but he couldn’t hide how he felt. He laughed all the way home.
Now，I think it’s funny too. But at the time I was terribly embarrassed. I thought that an invitation to have dinner meant the same thing in the United States as in my country. I guess you have to understand that your customs（习俗） are only your customs. When you visit a foreign country，you have to learn about their customs，too.
【小题1】Customs can be ________in different countries according to this passage.
