Does your school have any problems with discipline(纪律)? What happens when students step out of line?
Here are some examples of bad behaviour:
? Playing truant(逃学) (missing school without permission from parents).
? Stealing, smoking, hitting, swearing, running, kissing.
? Cheating on exams.
? Calling a teacher or another pupil a bad name.
? Not doing homework.
? Not listening or not paying attention in lessons.
? Wearing unsuitable clothes.
Here are some of the ways that UK school children can be punished:
? Exclusion（开除）: a pupil is asked to leave the school and not come back. The pupil has to find a new school or a different method of education.
? Suspension（停课）: a pupil cannot enter the building or attend lessons until the school has a meeting about their situation. Suspension can last from one to 45 days. The pupil is usually given work to do at home with a special teacher.
? Detention（拘留）: a pupil is asked to stay after school and work for 30-60 minutes before they can leave.
? Lines: a pupil has to write a sentence many times (e.g. 100 or more) on a sheet of paper, e.g. “I must not shout in class.”
Freya MacDonald, a 15-year-old pupil from Scotland, _________when she refused to accept her school’s punishment. Her family says that she was given 11 detentions for trivial things such as having fizzy drinks in class and coming into school through a fire door.
Freya says that repeated detentions ruined her right to an education under Scottish law and made it difficult for her to learn. So she refused to return until the school respected her civil rights. She wants the headmaster and her teachers to sign a letter to promise this. Hundreds of schools in Scotland were told not to use detention as a punishment because of her legal action.
Many UK schools now give parents a home&school contract（契约，合同）, explaining their discipline and rules. Parents must sign this document to agree that they accept the school’s rules and discipline and that they are responsible for their child’s behaviour.
小题1:The expression “step out of line” in Paragraph 1 probably means________

A．jump the queue	B．break the discipline
C．be later for school	D．fight with others.

小题2:What is the main purpose of the text?

A．To list common bad behavior in UK schools.

B．To show how UK schools deal with students’ parents.

C．To find out why more and more pupils break rules in UK schools.

D．To introduce how UK schools punish students with their discipline.

小题3:Which expression can be filled in the blank in the passage________.

A．covered the story

B．corrected her behavior

C．showed an interest

D．made the news

小题4:What is the best title for the passage?

A．Punishments in UK School

Computers can injure(伤害)you. Most other injuries happen suddenly．For example，if you fall off a bike and break your arms, it happens very quickly. But computer injuries happen slowly．
You probably know how to ride a bike safely. Now learn to use a computer safely．

Your eyes
Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be more than 50 centimeters from the screen. Don’t forget to look away from it sometimes. This gives your eyes a rest．
When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on(反射)the screen. If the window is in front of you，the sun and the screen will both shine into your eyes．
Your hands and wrists(手腕)
Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time, follow these three rules: 1) Rest your wrists on something.
2) Keep your elbows(肘)as high as the keyboard.
3) Stop sometimes and exercise your hands, wrists and fingers in a different way．
Your back
Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back or your neck. So you shouldn’t bend your back when you sit. The top part of the screen should be in front of your eyes. Your forearms, wrists, hands and the upper part of your legs should all be parallel(平行)to the floor. If you are sitting for a long time, get up every half an hour and exercise your arms, legs and neck．
Enjoy your computer, but use it safely．

In the past, going to a piano teacher was the only way to learn how to play the piano. You could have one lesson a week. If you didn’t have private(个人的) lessons, you could still learn piano, but you would have to learn it by yourself. This was easy for some, but very difficult for most. However, with technology as it is today, there is at last another way that you can take piano lessons. You can take an online course.
An online course can save you lots of money. If a private lesson costs 30 or 40 dollars per week, just think about how quickly that adds up. You can take a complete online course in piano by spending a small part of the money that you would pay for taking weeks of private lessons. Also, private lessons are only usually one hour per week. If you have questions during the rest of the week, or if you forget something that your teacher said, you will have to wait for your next lesson to continue your learning. However, online piano courses are quite different.
With an online piano course, you can work at your own pace(进度). You can also take as many lessons per week as you’d want, or go back and listen to your last lesson if you have forgotten anything. Most adults who want to learn how to play the piano enjoy being able to go back and listen to lessons they watched before. It can give you a good idea of what you were doing right, what you were doing wrong, and what you should be doing before the next lesson.
Of course, if you need someone to sit beside you and give you instant feedback(及时反馈) while you are playing, you are not suggested to choose an online course. But most adult learners think they can get their own type of feedback by watching the course again and again.
小题1:       is not mentioned in the passage to learn to play the piano.
A.Going to a piano teacher        B. Asking experts for information   C. Teaching oneself
小题2:Going to a piano teacher is much more        than having an online piano course.
A. expensive                   B. convenient                  C. interesting
小题3:If you choose an online piano course, you can          .
A. ask questions whenever you want
B. watch the lessons whenever you’d like
C. get some advice while you are playing the piano.
小题4:Most adults like to go back and listen to the lessons again because         .
A. they needn’t spend any extra money
B. they can ask some questions
C. they can know what they were doing right, what they were doing wrong
小题5:How many advantages of an online piano course have been introduced in the passage?
A. 2                           B. 3                         C. 4

Confidence is very important in daily life. It can help you to develop a healthy attitude. A study shows that the people who are more confident are much happier. They can have more chance to make themselves successful. But how to be more confident? Here are some suggestions:
Speak loud   When you are not confident, you can’t do well what you want to do. You speak in a voice so low that other people can hardly hear you. Try to speak loud enough so that people can hear you clearly. The high voice can help you become more confident.
Play sports   Physical exercise makes you tired but completely relaxed. A strong body helps you be full of confidence.
Encourage yourself Write down a list of things you did during the day to see how many things you have done well. Did you finish your homework? Did you tell a joke that made everybody laugh? Give yourself praise for the good things you’ve done.
Get rid of (消除) fear Fear comes along with failure. But it’s easy to overcome (克服) if you know that failure is part of your life. Don’t hide your head just because you said something stupid last time. Try to start again and believe you can do better.
