People joke that no one in Los Angeles reads;everyone watches TV, rents videos，or goes to the movies.The most popular reading material is comic books，movie magazines，and TV guides.City libraries have only 10 percent of the traffic that car washes have.But how do you explain this? A yearly book festival in west Los Angeles is booming year after year.People wait half an hour for a parking space to become available.
This outdoor festival, sponsored by a newspaper，occurs every April for one weekend. This year’s attendance was estimated at 70, 000 on Saturday and 75, 000 on Sunday. The festival consisted of 280 exhibitors. There were about 90 talks given by authors, with an audience question-and-answer period following each talk. Autograph (亲笔签名)seekers sought out more than 150 authors. A short food street sold all kinds of popular food and various foreign foods，from American hamburgers to Hawaiian shave ice (刨冰) drinks.Except for a $7 parking fee，the festival was free.Even so，some people avoided the food street prices by staying away and having their own sandwiches and drinks.
People came from all over California.One couple drove down from San Francisco. “This is our sixth year here now.We love it,” said the husband.“It’s just fantastic to be in the great outdoors，to be among so many books and authors，and to get some very good deals，too.”
The idea for the festival occurred years ago，but nobody knew if it would succeed.Although book festivals were already popular in other US cities，would Los Angeles residents welcome one?“ The citizens of the city are very unpredictable，”said one of the festival founders.

I hear many parents complain that their teenage children are rebelling (叛逆). I wish it were so. At your age you ought to be growing away from your parents. You should be learning to stand on your own feet. But take a good look at the present rebellion. It seems that teenagers are all taking the same way of showing that they disagree with their parents. Instead of starting acting independently, most of them are holding one another's hands for reassurance (放心).
They claim they want to dress as they please. But they all wear the same clothes. They set off in new directions in music. But they all end up listening to the same record. Their reason for thinking or acting in such a way is that the crowd is doing it. They have come out of their cocoon (茧) into a larger cocoon.
It has become harder and harder for a teenager to stand up against the popularity wave and to go his or her own way. Industry has firmly developed a market for teenagers. These days every teenager can learn from the advertisements what a teenager should have and be. This is a great roadblock for the teenager who wants to find his or her own path.
