After spending years searching for a planet with life, scientists may have found one. In September 2010, a team of US scientists discovered a planet called Gliese 581g. It has a surface temperature neither too hot nor too cold for liquid（液态）water. Scientists think there is a chance that the planet could have life.
The planet Gliese 581g goes around a star called Gliese 581, which is about 20 light-years from Earth. That is about 194 trillion（万亿）kilometres －500 million times farther away from us than the moon.
A spacecraft traveling at a one-tenth of the speed of light would reach Gliese 581g within about 220 years. A human can’t live that long, but robotic explorers could make the job easier. However, our fastest spacec raft don’t come anywhere near that one-tenth light-speed mark.
At present, scientists don’t know what the surface might be like on Gliese 581g. What they know is that the planet is at the right distance from its star to have liquid water. It’s also at the right distance to have an atmosphere that could protect the water if it is on the surface.
Although spacecraft won’t be getting there anytime soon, one way to look for life on Gliese 581g is to turn our radio telescopes（望远镜）towards the planet and search for radiation（放射）. By studying the radiation, scientists would find out about the chemicals（化学物质）around the planet and discover if Gliese 581g has an atmosphere. If it has one, studying the atmosphere would give us a good idea whether the planet has life or not. But it’ll probably be many years before we can do this properly.
People have been arguing about whether there is alien life on Gliese 581g. Any discussion about alien life is just guessing at this point, according to its discoverers.

名校课堂系列答案You’ve probably known the crazy traffic in Beijing. Sometimes the cars could hardly move for a long time. The terrible traffic is caused by the poor road and China’s ability to cope with (对付) so many cars on the road at the same time.
With more Chinese people buying cars every day, the problem seems to only get worse. But a design company called Shenzhen Hashi Future Parking Equipment has a possible solution: the super bus.
The super bus would carry up to 1,400 people in its passenger compartment (隔间). It would travel on a rail system that would be elevated (升高的) above the roads, so cars could drive under it. The bus will run on electricity and solar power, creating far less pollution than that from the cars it would be replacing (代替).
Beijing authorities haven’t decided whether to create railways for the super bus throughout the city. But they are willing to give it a test drive. Later 2010, the company will test for the first time and in 2011 and 2012, the company will test the super bus with passengers.
According to the government, Beijing is probably to have five million cars on the road by the end of 2010. So it seems to be necessary to start taking the bus instead soon.
【小题1】__________ caused the terrible traffic in Beijing.
| A．The drivers | B．The roads | C．The buses | D．The government |
| A．1,400 million | B．2,000 million | C．5 million | D．50 million |
| A．It is an interesting park. | B．It is a super bus. |
| C．It is a kind of equipment. | D．It is a design company. |
| A．The super bus will travel above the roads. |
| B．The super bus will produce more pollution. |
| C．The super bus will only hold several people. |
| D．The super bus is very small. |
A kind of little cars may some day take the place of today’s cars. If everyone drives such cars in the future，there will be less pollution from the cars. There will also be more space for parking cars in cities，and the streets will be less crowded. Three such cars can park in the space now needed for one car of the usual size.
The little cars will cost much less to own and to drive. Driving will be safer，too，as these little cars can go only 65 kilometers an hour. The cars of the future will be fine for getting around a city，but they will not be useful for long trips. Little cars will go 450 kilometers before needing to stop for more gas(汽油).
If big cars are still used along with the small ones，two sets of roads will be needed in the future. Some roads will be used for the big，quick cars and other roads will be needed for the slower，smaller ones.
【小题1】There is much pollution from the cars today because________.
| A．people drive big cars | B．the cars go 65 kilometers an hour |
| C．people drive small cars | D．the cars can go 450 kilometers an hour |
| A．smaller than | B．the same as | C．three times as large as | D．a little larger than |
| A．big cars cost less to own and to drive |
| B．the cars of the future will be much smaller than today’s cars |
| C．big cars are not useful for long trips |
| D．small cars are faster than big ones |
| A．there will be fewer cars | B．there will be fewer people in the street |
| C．driving future cars will be safe | D．future cars will be much smaller |
| A．there will be too many cars in the future |
| B．more and more people will get around a city |
| C．big cars will be used along with the small ones |
| D．it looks more beautiful to have two sets of roads |
When we talk about intelligence(智力)，we do not mean the ability to get good scores on certain kinds of tests or even the ability to do well in school．By intelligence we mean a way of living and behaving(表现)，especially in a new situation．If we want to test intelligence，we need to find out how a person acts instead of how much he knows what to do．
For example，when in a new situation，an intelligent person thinks about the situation，not about himself or what might happen to him．He tries to find out all can be，and then he acts immediately and tries to do something about it．Probably he isn’t sure how it will all work out，but at least he tries．And if he cannot make things work out right，he doesn’t feel ashamed(羞愧)that he failed，he just tries to learn from his mistakes．An intelligent person，even if he is very young，has a special outlook(看法)on life，a special feeling about life，and how he fits into it．
If you look at children，you’ll see the great differences between what we call “bright” children and “non-bright” children．They are actually two different kinds of people，not just the same kind with different amount of intelligence．For example，the bright child really wants to find out about life, and he tries to get in touch with everything around him; while the unintelligent(不聪明的) child keeps more to himself and his own dream-world：he seems to have a wall between him and life in general．
【小题1】According to this passage，intelligence is the ability to_________．
| A．get some high scores on some tests |
| B．do well in school |
| C．deal with life |
| D．have a lot of book knowledge |
| A．knows more about what might happen to him |
| B．is sure of the result he will get |
| C．cares more about himself |
| D．keeps his mind on what to do about the situation |
| A．try not to feel ashamed |
| B．learn from his mistakes |
| C．try to find all he could |
| D．make sure what result he would get |
| A．are two different types of children |
| B．are different mainly in their degree of cleverness |
| C．have differences only in their way of thinking |
| D．have different knowledge about the world |
It’s a long-awaited day for China. The navy now has its first aircraft carrier(航空母舰), Liaoning.
It’s a unique experience to get to know the life in the carrier. The carrier is just like a small city on the sea. It has all the functions for daily life. There are 4 words to sum up its characters: big, small, much and high. The carrier Liaoning is such a huge one that the total length of the whole corridor（过道）could reach over 20 kilometers. But the living space for the sailors（水手）is quite small. That’s because the carrier is designed for researching purposes, rather than comfortable living. Over 1,000 sailors, both men and women, are living onboard. They are arranged among over 3,000 tiny rooms below the deck. For visitors, it’s so easy to get lost. So the first thing the new sailors have to learn is their way around. The number of female sailors is much less than that of the males, taking about 5 percent of the total. But they play a key role in carrying out some special missions.
Also, you will be surprised by the high level of education of today’s sailors. The captain said that over 90 percent of the sailors are college graduates. Six hold Doctor’s Degrees and 45 have a Master’s. The whole team is young but vigorous（朝气蓬勃的）. The complex work on the carrier requires high management abilities for the commanders onboard(在船上).
【小题1】Why do we visitors get lost easily inside the carrier?
| A．Because they don’t have a map. |
| B．Because the living space is quite small. |
| C．Because there are too many corridors for rooms. |
| D．Because the corridor inside the carrier is too long. |
| A．The aircraft carrier is high since it is just like a small city. |
| B．Most of the soldiers received good education. |
| C．The expense（花费）to run a carrier is high. |
| D．The high-level of their training. |
| A．Liaoning is our country’s first aircraft carrier. |
| B．Most of the sailors on the carrier are college graduates. |
| C．There are far fewer women sailors than men sailors on the carrier. |
| D．It is comfortable for the sailors to live in the carrier. |
Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.
If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering(不开花的) plants.
Flowering plants can make seeds(种子). The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit.
Most non-flowering plants do not grow from seeds. They grow from spores(孢子). Spores are very, very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores fall on wet and shady(阴凉的) places, they usually grow into new plants.
【小题1】What fact does the passage lead you to believe?
| A．Of all living things, animals are most important. |
| B．Spores are seeds. |
| C．All fruits of flowering plants have seeds. |
| D．Without plants, man will die out. |
| A．how plants can make food from air |
| B．how spores grow into new plants |
| C．why some plants have no seeds |
| D．why non-flowering plants are more important than flowering plants |
| A．a story book | B．a novel |
| C．a science magazine | D．a laboratory report |
Imagine the situation. You are driving along a desert or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car breaks down. It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is a device(装置) which uses satellites (卫星) to find the user’s position(位置). It can find your position to within 20 metres. A GPS cannot start your car, but at least you will know where you are.
GPS, which means Global Positioning System, is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put in your pocket. It is sometimes put into a watch or a telephone. We also find GPS devices in cars, planes, or boats. Some of these devices have electronic maps, so you know where you are. For example, in a city they can tell you the name of the street.
There are three parts to the Global Positioning System. The first part is the receiver. You can hold it in your hand, or have it fixed into your car, plane, etc. The second part is a group of satellites orbiting the Earth. The receiver contacts at least four of the satellites and calculates(计算) its position. The third part of the system is a network of ground stations. They are all over the world. They control the satellites and make sure they are working well.
Some people think that in the future the GPS will be as common as the mobile. They are becoming cheaper and more and more accurate(精确的). There are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again.
【小题1】According to the passage, with the help of the GPS, people __________.
| A．can’t be lost in a new city |
| B．can’t find their way in different countries |
| C．can learn about the culture of an unknown place |
| D．can spend the least time getting to another place |
| A．there are three parts to the GPS |
| B．a GPS can’t be put into a watch |
| C．a GPS can help you start your car |
| D．the GPS are becoming more and more expensive |
| A．Receivers | B．GPS devices | C．Satellites | D．Ground stations |
| A．the history of the GPS | B．the introduction of the GPS |
| C．the shape of the GPS | D．the three parts of the GPS |
| A．All GPS devices have electronic maps. |
| B．People in many countries will use the GPS for free. |
| C．The receiver of the GPS contacts at least five of the satellites. |
| D．The GPS will become more and more common in everyday life. |
An American friend has invited you to visit his family. You’ve never been to an American’s home before, and you’re not sure what to do. Should you take a gift? How should you dress? What time should you arrive? What should you do when you get there? Glad you asked. When you’re the guest, you should just make yourself at home. That’s what hospitality(款待) is all about: making people feel at home when they’re not.
The question of whether or not to bring a gift often makes guests squirm（难为情）. Giving your host a gift is not just a social manner in some cultures-it’s expected. But in American culture, a guest is not necessary to bring a present. Of course, some people do bring a small present to their host to show their thanks. The right gifts for the host might be flowers, candy, and you can bring toys if the family has small children. If you choose not to bring a gift, don’t worry. No one will even notice.
【小题1】The passage talks about ______.
| A．where to find a friend in need | B．what to do while visiting your friends |
| C．how to make friends | D．when to visit your friend |
| A．弊端 | B．礼节 | C．趋势 | D．挑战 |
| A．bring a bundle of beer |
| B．bring him some beautiful clothes |
| C．bring delicious food |
| D．buy a bunch of fowlers |
| A．you are impolite if you don’t bring a gift |
| B．how to pick out a gift for our friend |
| C．the host won’t care if you don’t bring a gift |
| D．bringing a gift is very necessary |
Two students started quarreling at school. One student shouted dirty words at the other, and a fight began.
What can be done to stop fights like this at school? In some schools, disputants(争执者) sit down with peer mediators (同龄调解者). Peer mediators are usually students with special training in this kind of problems.
Peer mediators help disputants to talk in a friendly way. Here are some of the ways they use.
1. Express what you think clearly but don't say anything to hurt the other. Begin with "I feel" instead of "You always".
2. Listen carefully to what the other person is saying. Don't stop the other person's words.
3. Keep looking at the other person's eyes when he or she speaks.
4. Try to see the problems on the other person's side.
5. Never put anyone down. Saying things like "You are foolish (愚蠢的)" makes the talk difficult.
6. Try to find a result that makes both people happy.
Peer mediators never decide on the winner. They don't decide who is right or who is wrong. Instead they help disputants to find their own "win-win" result. A "win-win" result can make everyone feel good.
Peer mediators' work is often successful just because it gets disputants to talk to each other. And getting disputants to talk to each other is the first step in finding a "win-win" result.
【小题1】Peer mediators' work is _.
| A．to teach lessons to disputants |
| B．to help find a way to make both disputants happy |
| C．to find out who starts the quarrel |
| D．to give students some special training |
A. 贬低任何人 b.落后于任何人
C. 奉承任何人 d.向任何人低头
【小题3】What's the first step in finding a "win-win" result?
| A．Letting disputants be afraid of peer mediators. |
| B．Letting disputants feel peer mediators are kind. |
| C．Getting disputants to talk to each other. |
| D．Making disputants feel good by telling funny stories. |
| A．disputants will realize they are wrong |
| B．disputants will understand peer mediators better |
| C．it is easy for peer mediators to decide who is right |
| D．it is hard for peer mediators to get a "win-win" result |
| A．All schools have peer mediators. |
| B．Peer mediators are usually students. |
| C．When disputants are speaking, peer mediators can stop their words at any time. |
| D．Peer mediators can make disputants get a "win-win" result every time. |
