The Internet has bee part of teenage life．

A new report on 3,375 students aged from 10 to 18 in seven Chinese cities found that 38 percent of them believe they use the Internet often．While most of them get useful information and use the Internet to help in their studies, some are not using it in a good way．In order to help young people use the Internet in a good way, a textbook on good Internet behaviour has started to be used in some Shanghai middle schools this term．The book uses real examples to teach students all about good ways of using the Internet．The book gives useful advice such as it's good to read news or find helpful information to study．

Some students also make online friends．But if you are meeting a friend offline, make sure your parents know．Teachers and parents all think the book is of great help．A teacher said the book would be a guide for teens using the Internet．She believes it will keep students away from bad sites．\．\book will teach students how to be a good person in the online world．\41．The textbook mainly tells us ______． A．why we should use the Internet B．how to study using the Internet C．how to use the Internet correctly D．how to get help from others

B

I was very disappointed not to be able to go to the jazz concert last Friday．The advertisement in the paper said that you could buy tickets at the theatre box in Richland Hills any day between 10:00 and 4:00．Since I work from 9:00 to 5:30, the only time I could go to the theatre was during my 45-minute lunch break．Unfortunately, the theatre is on the other side of the town, and the bus service between my office and Richland Hills is not very good．But if you are lucky, you can make the round trip in 45 minutes．Last Monday．I stood at the bus stop for 15 minutes waiting for the bus．By the time I saw one e around the corner, there was not enough time left to make the trip．So

I gave up and went back to the office．The same thing happened on Tuesday, and again next day．On Thursday, my luck changed．I got on a bus right away and arrived at the theatre in exactly 20 minutes．When I got there, however, I found a long line of people at the box office, I heard one man say he had been waiting in line for over an hour．Realizing I would not have enough time to wait in line．I caught the next bus and headed back across the town．By Friday I realized my only hope was to make the trip by taxi, it was expensive, but I felt it would be worth it to hear the concert．The trip by taxi only took 10 minutes, but felt like an hour to me．When I got to the theatre, I was relieved to see that nobody was waiting in line．The reason, however, I quickly discovered, was that they had already sold all the tickets．

45．The man learned that there would be a concert last Friday． A．from his friends B．from one of his work-mates C．over the radio D．from the newspaper

46．He tried to go to the theatre every day but managed to get there only _______． A．once B．twice C．three times D．four times 47．One day the man took _______ to get to the theatre by bus． A．forty-five minutes B．fifteen minutes C．just twenty minutes D．over an hour

48．The underlined word \． A．surprised B．pleased C．puzzled D．sorry

C

Most musicians agree that the best violins were first made in Italy．They were made in Cremona, Italy, about 200 years ago．These violins sound better than any others．They even sound better than violins made today．Violin makers and scientists try to make instruments like the old Italian violins．But they aren't the same．Musicians still prefer the old ones．No one really knows why these old Italian violins are so special, but many people think they have an answer．

Some people think it is the age of the violins．They say that today's violins will also sound wonderful someday．But there is a problem here．Not all old violins sound wonderful．Only those from Cremona are special．So age cannot be the answer．There must be something different about Cremona or those Italian violin makers．

Other people think the secret to those violins is the wood．The wood of the violin is very important．It must be from certain kinds of trees．It must not be too young or too old．Perhaps the violin makers of Cremons knew something special about wood for violins．

But the kind of wood may not be so important．It may be more important to cut the wood in a special way．Wood for a violin must be cut very carefully．It has to be the right size and shape．The smallest difference will change the sound of the violin．Musicians sometimes think that this was the secret of the Italians．Maybe they understood more than we do about how to cut the wood．

Size and shape may not be the answer either．Scientists measured these old violins very carefully．They can make new ones that are exactly the same size and shape．But the new violins still do not sound as good as the old one．Some scientists think the secret may be the varnish, which covers the wood of the violin and makes it look shiny．It also helps the sound of the instrument．No one knows what the Italian violin makers used in their varnish（漆）．So no one can make the same varnish today．

There may never be other violins like the violins of Cremona．Their secret may be lost forever．Young musicians today hope this is not true．They need fine violins．But there aren't very many of the old violins left．Also, the old violins are very expensive．Recently, a famous old Italian violin was sold for about US $ 300,000! 49．This passage is about ________． A．making violins B．musical instruments C．scientific ideas D．the old Italian violins

50．The best violins ____________． A．are made with modern techniques B．were lost many years ago C．were made in Italy 200 years ago D．were made by scientists 51．Some people think that modern violins __________． A．will sound better in the future B．will sound worse in the future C．sound wonderful naturally

D．will never be as old as those from Cremona 52．Violins made today ________． A．look the same as the old ones B．sound the same as the old ones C．are better than the old ones D．have the same varnish as the old ones

D

People believe that climbing can do good to health．Where can you learn the skill of climbing then? If you think that you have to go to the mountains to learn how to climb, you' re wrong．Many Americans are learning to climb in city gyms（体育馆）．Here, people are learning on special climbing walls．The climbing wall goes straight up and has small holding places for hands and

feet．

How do people climb the wall? To climb, you need special shoes and a harness（保护带）around your chest to hold you．There are ropes（绳索）tied to your harness．The ropes hold you in place so that you don' t fall．A beginner's wall is usually about 15 feet high, and you climb straight up．There are small pieces of metal that stick out for you to stand on and hold on to．Sometimes it's easy to see the next piece of metal．Sometimes, it's not．The most difficult point is to control your fear．It's normal for humans to be afraid of falling, so it's difficult not to feel fear．But when you move away from the wall, the harness and the ropes hold you, and you begin to feel safe．You move slowly until you reach the top．

Climbing attracts people because it's good exercise for almost everyone．You use your whole body, especially your arms and legs．This sport gives your body a plete workout．When you climb, both your mind and your body can bee stronger． 53．What can we infer from the passage?

A．People are fairly interested in climbing nowadays． B．It is impossible to build up one's body by climbing． C．People can only learn the skill of climbing outdoors． D．It is always easy to see holding places in climbing． 54．The most difficult thing to do in wall climbing is _______．

A．to tie ropes to your harness B．to control your fear C．to move away from the wall D．to climb straight up 55．The word \

A．settlement B．exercise C．excitement D．tiredness 56．Why does the author write this passage? A．To tell people where to find gyms．

B．To prove the basic need for climbing． C．To encourage people to climb mountains．

D．To introduce the sport of wall climbing．

E

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 paperbacks（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（诗人）．

57．It can be inferred from the passage that ． A．TV programs are a chief provider of knowledge B．cinemas are the best choice in getting information C．reading is a cheap way of learning and having fun D．newspapers are an expensive way to enjoy oneself

58．What does the sentence \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．

59．Which of the following is mainly discussed in the last paragraph? A．Types of books． B．Kinds of dictionaries． C．Lists of history books． D．Collections of stories and poems． 60．What can we learn from the passage?

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 paperbacks． D．More people like TV programs about famous men．
