When a group of children politely stop a conversation with you, saying: “We have to go to work now,” you’re left feeling surprised and certainly uneasy. After all, this is the 1990s and the idea of children working is just unthinkable. That is, until you are told that they are all pupils of stage schools, and that the “work” they go off to is to go on the stage in a theatre.

  Stage schools often act as agencies(代理机构)to supply children for stage and television work. More worthy of the name “stage school” are those few places where children attend full time, with a training for the theatre and a general education.

  A visit to such schools will leave you in no doubt that the children enjoy themselves. After all, what lively children wouldn’t settle for spending only half the day doing ordinary school work, and acting, singing or dancing their way through the other half of the day?

 Then of course there are times for the children to make a name and make a little money in some big shows. Some stage schools give their children too much professional work at such a young age. But the law is very tight on the amount they can do. Those under 13 are limited to 40 days in the year; those over 13 to 80 days.

 The schools themselves admit that not all children will be successful in the profession for which they are being trained. So what happens to those who don’t make it? While all the leading schools say they place great importance on children getting good study results, the facts seem to suggest this is not always the case.

 People would stop feeling uneasy when realizing that the children they’re talking to________.

    A. attend a stage school      B. are going to the theatre

    C. have got some work to do     D. love singing and dancing

   In the writer’s opinion, a good stage school should ________.

    A. produce star performers

    B. help pupils improve their study skills

    C. train pupils in language and performing arts

    D. provide a general education and stage training.

 “Professional work” as used in the text means ________.

    A. ordinary school work       B. money-making performances

    C. stage training at school      D. acting, singing or dancing after class

  Which of the following best describes how the writer feels about stage schools?

    A. He thinks highly of what they have to offer.    

    B. He favours an early start in the training of performing arts.

    C. He feels uncomfortable about children putting on night shows.

    D. He doubts the standard of ordinary education they have reached.

Bad behavior is something that most people don’t want to tolerate. However, we have had to tolerate it more and more with each passing year. There seems to be no concern for other people’s feelings; nor do we seem to care about other people’s property. We live in an age where saying what is on our minds has priority over any harm that it might do.

There are ways to deal with bad behavior in modern times, though. Too many of us let bad behavior go because we don’t want to rock the boat. This is the time that you should rock the boat and rock it hard. Let people know that you expect it to change. That is the key to dealing with bad behavior. If it continues, take the proper action for the situation you are in. If you have developed the habit of bad behavior, take a hard look at it and then change it. You can’t expect others to behave well if you aren’t willing to look at your own bad behavior and change it.

If you don’t have control over anything in a situation, just walk away from it and move on to something that you do have control over. You needn’t feel ashamed of that. Besides, you must stand firm in what you believe. You can’t control what other people do, but you can control what you do about it. You can’t go wrong if you stand firm in what you believe. Understanding your responsibility is also important. Don’t try to take on the responsibility for other people’s behavior. Take care of what you have to and do it in the way you know it should be done. The rest will take care of itself.

Bad behavior is on the rise with more and more people behaving badly without having to pay any consequences. Worry about how you behave rather than how others behave. Pretty soon, it just may catch on.

1.It can be inferred from Paragraph 1 that _____________.

A. bad behavior is common today

B. bad behavior is sure to hurt people deeply

C. people behave badly because of carelessness

D. people are more understanding than before

2.When dealing with people’s bad behavior, you are advised to ____________.

A. fight it bravely whenever it happens

B. ignore it if it is beyond your control

C. let it go to avoid trouble

D. make people feel ashamed of their bad behavior

3.Why do many people behave badly according to the passage?

A. Because bad behavior is often ignored.

B. Because people are often influenced by others.

C. Because people aren’t punished for their bad behavior.

D. Because people haven’t realized its consequences.

A funny thing happened on the way to the communications revolutions: we stopped talking to one another.

I was walking in the park with a friend recently,and his cell phone rang, interrupting our conversation. There we were, walking and talking on a beautiful sunny day and…I became invisible, absent from the conversation.   

The telephone used to connect you to the absent. Now it makes people sitting next to you feel absent. Why is it that the more connected we get, the more disconnected I feel? Every advance in communications technology is a tragedy to the closeness of human interaction. With email and instant messaging over the Internet, we can now communicate without seeing or talking to one another, With voice mail, you can conduct entire conversations without ever reaching anyone. If my mom has a question, I just leave the answer on her machine.

As almost every contact we can imagine between human beings gets automated, the alienation index goes up. You can't even call a person to get the phone number of another person my more. Directory assistance is almost always fully automated.

I am not against modern technology. I own a cell phone, an ATM card a voice mail system, and an email account. Giving them up isn't wise…they're a great help to use. It's some of their possible consequences that make me feel uneasy.  

More and more .I find myself hiding behind e-mail to do a job meant for conversation. Or being relieved that voice mail picked up because I didn't really have time to talk, The industry devoted to helping me keep in touch is making me lonelier…or at least facilitating my antisocial instincts.

So I've put myself on technology restriction: no instant messaging. with people who live near me,no cell phoning in the presence of friends, no letting the voice mail pick up when I'm at home.

1.Which of the following would be the best title of the passage?   

A.The Advance of Communications Technology

B.The Consequences of Modern Technology

C.The Story of Communications Revolution

D.The Automation of Modern Communications

2.The sentence “Now it makes people sitting next to you feel absent,”means that       .

A.the people sitting beside you have to go away to receive a phone call

B.you can hardly get in touch with the people sitting beside you

C.modem technology makes it hard for people to have a face-to-face talk

D.people can now go to work without going to the office

3.The writer feels that the use of modern communications is        

A.encouraging

B.disappointing

C.satisfying

D.embarrassing

4.The passage implies that        .

A.modern technology is bridging the people.

B.modern technology is separating the people

C.modern technology is developing too fast
