What happens after an earthquake? We send in rescue(救援) dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
How does it work? First, the rat is trained to smell people. When this happens, the rat’s brain gives a signal. This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University, New York, says, “ ‘Robot’ noses don’t work well when there are other smells around. Rats are good at that.” Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity.
The “ rat project” is not finished, but Julie Ryan of International Rescue Corps in Scotland says, “ It would be fantastic. A rat would get into spaces we couldn’t get to and a rat would get out if it wasn’t safe.” Perhaps for the first time in history, people will be happy to see a rat in a building ( but only after an earthquake, of course.)

1.” What’s the matter?” “I went to a party last night, so I…”
2.”I feel so tired these days.” “I think you’d better…”
3.”Of course, she never stops talking. She is one of the most…”

What made these average students change so much to become top students?The only difference was the change in their teachers’ attitude(态度). Because the teachers believed that these five kids were the top students,they expected(期望) more from them. And so these five average students began to believe and expect more from themselves. So they worked harder to do as well as they could.
Do you know why? If you expect the best from people, they’ll usually want to give you their best. A great leader said, “Treat(对待) a person just how he appears to be on the outside, and you’ll make him even worse. But treat a person like he’s already a success,and you’ll help make him the best he can be.”
Like the true story of 7-year-old Johnny, his teacher got so angry with him that one day she said,“Johnny,you’re the naughtiest(最顽皮的) boy in this class. I’m sure you’ll never change.” The next year Johnny had a new teacher. And on the first day of class,she met with Johnny after school and said,“Johnny, I’ve heard a lot about you! But do you know that I don’t believe a word of it.” And every day after that, this new teacher treated Johnny as if he was one of the smartest students even when Johnny did naughty things. Later on, Johnny became a school leader. Because that’s the power of our belief(信任) and attitude(态度) toward children.

If you go to sleep on your back, you’re a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don’t like to displease people. So you never express your real feelings. You’re quite shy and you aren’t quite sure of yourself.
If you sleep on your stomach, you are a rather secretive person. You worry a lot and you’re always easily upset. You always stick to your own opinions or judgment, but you don’t raise your hopes too much. You usually live for today not tomorrow. This means that you enjoy having a good time.
If you sleep curled up(蜷缩), you are probably a very nervous person. You have a low opinion of yourself and so you’re often defensive. You’re shy and you don’t normally like meeting people. You prefer to be on your own. You’re easily hurt.
If you sleep on your side, you have usually got a well—balanced personality. You know your strengths and weakness. You’re usually careful. You believe in yourself. You sometimes feel anxious, but you don’t often get sad. You always say what you think even if it makes people rather angry
小题1:You may find the passage in .
A. a science magazine B A guide book
C. a sports newspaper D. a story book

But some people can’t hear any sound at all. Some are born deaf. Others can hear well in their childhood, but too many loud sounds hurt their ears later on.
Many people in China can’t hear ordinary sounds clearly. A large number of them are children. Most of them are born with good hearing. But six children of every 1,000 have hearing problems when they are born. And if a child has hearing problems, he or she usually will also have some learning problems at school.
A lot of things can cause hearing problems. For example, too much earwax is not good for our hearing. And noise louder than 85 decibels (分贝) can hurt our ears and make us lose our hearing for a short time or even for ever.
Hearing is important for all of us. So we should do our best to give our ears special care. Don’t forget to do the following:
● Try to stay away from places with too much noise. If you have to go, wear earplugs. A pair of good earplugs can cut the noise by 30 decibels.
● When swimming, remember to put earplugs into your ears to stop water from getting in.
● Never put anything sharp into your ears. If you think you have too much earwax, ask your mum or dad to help you clean it out.
Keep these things in mind! Then you won’t be saying “WHAT? WHAT?” when you are older.
小题1:What does the underlined word “earwax” mean in the passage?
A.耳膜 | B.耳鸣 | C.耳垢 | D.耳疾 |
A.tell us many beautiful sounds |
B.describe the uses of ears |
C.explain the kinds |
D.show the importance of ears |
A.Hearing problems caused by diseases. |
B.People with hearing problems. |
C.Ways to protect our ears. |
D.Danger of loud noise. |
A.a little earwax |
B.learning problems at school |
C.noise louder than 85 decibels |
D.earplugs that can only cut noise by 15 decibels |
A.when you get older, you know it’s not polite to ask “What?” |
B.when you get older, you still have good hearing |
C.when you get older, you won’t ask questions |
D.the older you are, the fewer questions you’ll have |
You may like at least some kind of music. But the problem is that, in lots of places, you’re made to hear somebody else’s choice in music. Say you’ve just landed at an airport. At the airport, the “background” (背景)music may be played loudly.
When you are on the way to your hotel, there may be another kind of music played by the taxi driver. Then you finally reach your hotel. But when you are taking the elevator(电梯),there is elevator music.
You go out to dinner and end up in a place where the owner of the restaurant thinks music will help make you eat more and spend more. Then a person playing the violin comes around. This is called the “music wallpaper”. It is to make you buy more and eat a lot. Even the government thinks this is “noise pollution,” especially when the music is too loud.
Noise pollution may be bad for our hearing. It’s also bad for some of our daily activities, such as sleeping, conversations and so on.
The fact that you can’t see, taste or smell it may help explain why it has not received as much attention as other kinds of pollution, such as air pollution or water pollution. The air around us is always filled with sounds, but most of us would not think we are surrounded(包围) by noise. This can be bad for our health. So many people like soft and quiet music in their house.
小题1:In the restaurant, the music is to make you _____________.
A.have a nice meal |
B.eat more food and spend more money |
C.enjoy some wonderful music |
D.have a great time in the restaurant |
A.food pollution | B.water pollution |
C.air pollution | D.noise pollution |
A.it’s played at the airport |
B.it’s played by the taxi driver |
C.it’s played when you are taking the elevator |
D.you are made to hear someone else’s choice in music |
A.music that is too loud is bad for our health |
B.people pay as much attention to noise pollution as they do to air pollution |
C.people like loud music in their house |
D.most people think that there’s lots of noise around us |
