For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner.Like a border conflict between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?

Both sides want peace, but neither feels it has any power to stop the conflict.In part, this is because neither is willing to admit any responsibility for starting it.From the parents’ point of view, the only cause of their fight is their adolescents’ complete unreasonableness.And of course, the teens see it in exactly the same way, except oppositelyBoth feel trapped.

In this article, I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap.The first no-win situation is quarrels over unimportant things.Examples include the color of the teen’s hair, the cleanliness of the bedroom, the preferred style of clothing, the child’s failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends.Second, blaming.The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong.Third, needing to be right.It doesn’t matter what the topic is.The laws of physics or the proper way to break an egg —the point of these arguments is to prove that you are right and the other person is wrong, for both wish to be considered an authority—someone who actually knows something — and therefore to command respect.Unfortunately, as long as parents and teens continue to assume that they know more than the other, they’ll continue to fight these battles forever and never make any real progress.

1.Why does the author compare the parent-teen war to a border conflict?

A.Both can continue for generations.

B.Neither can be put to an end.

C.Neither has any clear winner.

D.Both are about where to draw the line.

2.What does the underlined part in Paragraph 2 mean?

A.The teens cause their parents to mislead them.

B.The teens agree with their parents on the cause of the conflict

C.The teens blame their parents for starting the conflict.

D.The teens tend to have a full understanding of their parents

3.Parents and teens want to be right because they want to ________.

A.give orders to the other                  B.gain respect from the other

C.know more than the other                D.get the other to behave properly

4.What will the author most probably discuss in the paragraph that follows?

A.Solutions for the parent –teen problems.

B.Examples of the parent –teen war.

C.Causes for the parent –teen conflicts.

D.Future of the parent-teen relationship.

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 part 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 complete workout. When you climb, both your mind and your body can become stronger.
【小题1】What can we infer from the passage?

A.People are fairly interested in climbing nowadays.
B.It’s impossible to build up one’s body by climbing.
C.People can only learn the skill of climbing outdoors.
D.It’s always easy to see holding places in climbing.
【小题2】The most difficult thing to do in wall climbing is _________.
A.to tie ropes to your harnessB.to control your fear
C.to move away from the wallD.to climb straight up
【小题3】The word “workout” underlined in the last paragraph most probably means      .
A.settlementB.exercise
C.excitementD.tiredness
【小题4】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.

Technology: Taking the good without the bad?

Very soon, unimaginably powerful technologies will remake our lives.This could have dangerous consequences, especially because we may not even understand the basic science underlyi ng them.There’s a growing gap between our technological capability and our basic scientific understanding.We can do very clever things with the technology of the future without necessarily understanding some of the science underneath, and that is very dangerous.

The technologies that are particularly dangerous over the next hundred years are nanotechnology (纳米技术), artificial intelligence and biotechnology.The benefits that they will bring are beyond doubt.But they are going to be very, very dangerous.I’m working in the field of artificial intelligence.I have a model design for something that might be 50,000 million times smarter than the human brain.Target date is 2010.The only thing that's not possible in the film Terminator(终结者) is that the people win.If you're fighting against technology w hich is 50,000 million times smarter than you, you probably will not win.

Nanotechnology.We've all heard of the grey glue problem, that self-replicating nanotech devices might keep on copying until the world has become sticky glue.And certainly in biotechnology, we've really got a big problem because it's converging with nanotechnology and IT.Once you start mixing nanotech with organisms and you start feeding nanotech-enabled bacteria, we can really go an awful lot further than the Borg in Star Trek(星际迷航).And those superhuman organisms might not like us very much.

Eventually these technologies will become routine.That’s a threat to humanity.I don’t think it’s possible to slow it down.So what we need to do is accelerate the scientific research and try to get some extra tools.The problems facing us in the future are getting bigger and bigger.I think if we don’t get some proper science done, the future is hopeless indeed.

1.From the text, we know that the author’s greatest concern is         

A.our lack of technological understanding of the process involved

B.our lack of technological capability

C.creating technology without really understanding the basic science

D.Our refusal to face the consequences of the technology we create

2.It can be inferred from the text that the author         

A.thinks people overvalue the capabilities of technology

B.is not optimistic that artificial intelligence will always be used positively

C.thinks that we should take science fiction movies more seriously

D.believes artificial intelligence is the greatest threat we face technologically

3.Why does the author say it is not possible in the film Terminator that the humans win?

A.Because the power of the technology is exaggerated(夸大).

B.Because the strength of the machines is much greater.

C.Because machines with that much intelligence can easily defeat humans.

D.Because human beings are not courageous enough to win the battle.

I have to get my health in check , not only for me but because I promised my 9-year-old son. I’ll make good food and lifestyle choices. I miss being thin, and it’s time to get it back.

CELEBRATE

What good is having it if I’m not taking time to enjoy it? I have a wonderful job, a happy family, and so much to be thankful for. So how come I spend all my time working? Last summer my family took our first vacation in four years, the best thing I’ve done for myself and my family in a long time. This year, I’m making sure to take time to enjoy life and celebrate its many blessings.

阅读下面短文,并根据短文后的要求回答问题(请注意问题后的字数要求)。

[l]Fear and pain are two of the most useful things that human beings and animals have, if they are properly used. If fire did not hurt when it burnt, children would play with it until their hands were burnt away. Similarly, if pain existed but fear didn’t, a child would burn himself again and again, because fear would not warn himself to keep away from the fire that had burnt himself before. A really fearless soldier is not a good soldier because he will soon be killed; and a dead soldier is of no use to his army. Fear and pain are therefore two guards without which human beings and animals might soon die out.

[2] In our first sentence we suggested that fear should be properly used. If, for example, you never go out of your house because of the danger of being knocked down and killed in the street by a car, you are letting fear rule you too much. Even in your house you are not absolutely safe: A plane may crash on your house, or you may get cancer!

[3] The important thing is not to let fear rule you, but to use fear as your servant and guide instead. Fear will warn you of dangers; then you have to decide what action to take.

[4] In many cases, you can take quick and successful action to avoid the danger. For example, you see a car coming straight towards you. Fear warns you, then you jump out of the way, and all is well.

[5] In some cases, however, you decide that there is nothing that you can do to ___________. For example, you can’t prevent a plane crashing onto your house. In this case, fear is no longer of any use, and you have to try to overcome it.
