Now satellites are helping to forecast（預(yù)報(bào)）the weather.  They are in space, and they can reach any part of the world.  The satellites take pictures of the atmosphere（大氣）, because this is where the weather forms（形成）.  They send these pictures to the weather stations.  So meteorologists（氣象學(xué)家）can see the weather of any part of the world.  From the pictures, the scientists can often say how the weather will change.　　 Today, nearly five hundred weather stations in sixty countries receive satellite pictures.  When they receive new pictures, the meteorologists compare（比較）them with earlier ones.  Perhaps they may find that the clouds have changed during the last few hours.  This may mean that the weather on the ground may soon change, too.  In their next weather forecast, the meteorologists can say this.
　 So the weather satellites are a great help to the meteorologists.  Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours.  Now they can make good forecasts for three or five days.  Soon, perhaps, they may be able to forecast the weather for a week or more ahead（提前）.
小題1:Satellites travel _____________.
A．in spaceB．in the atmosphereC．a(chǎn)bove the groundD．a(chǎn)bove space

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（液態(tài)）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（萬億）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（望遠(yuǎn)鏡）towards the planet and search for radiation（放射）. By studying the radiation, scientists would find out about the chemicals（化學(xué)物質(zhì)）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.
小題1:What did scientists find in September 2010?
A．A planet with water.B．A planet similar to the earth.
C．A planet without life.D．A planet near the earth.
小題2:According to the article, Gliese 581g ________.
A．is at the right distance from its starB．moves around the earth
C．is as far away from us as the moonD．can be reached in about 220 years
小題3:Paragraph 5 is mainly about ______.
A．the possibility of living on Gliese 581g
B．the kinds of chemicals around Gliese 581g
C．the way of looking for life on Gliese 581g
D．the aim of studying the radiation on Gliese 581g
小題4:Which of the following is the best title for the passage above?
A．Gliese 581g, a Likely Living PlanetB．Gliese 581, a Likely Living Planet
C．Gliese 581g and Its StarD．Gliese 581g and Radiation

Is learning a foreign language ever easy? Yes. If you are five and move to another country, you will quickly pick up the language. But what about for the rest of us who are no longer five, and need to be polite when traveling for business or for pleasure? I think that answer is also yes. Language learning can be easy if you don’t want or need to learn too much.
The key to successful language learning in my mind is not to set the goal too high. It is rather like running. Even if you run twice a week, you don’t necessarily want to be able to run a marathon (馬拉松). You might just want to keep a level of fitness. I think the same can be true for language learning.
Let’s get back to the goal. If you decide to learn ten words in a foreign language before visiting the country, you know that you will be sure to do this. However, if you decide to talk to people with great fluency (流利), unless you are quite a talented person, you will probably fail and give up in half-way.
It is also far easier to start learning a foreign language than to finish. In other words, the better you are, the slower it can be to improve, because you will not be able to move further because of grammar, making sentences, learning less common words, etc. If you are only trying to learn a few foreign words and sentences, you will enjoy faster progress, have more fun, and won’t have to spend too much time.
The idea of learning only a few hundred words in a language, and then stopping, isn’t the usual way to language learning, but it can be a very meaningful and enjoyable activity.
小題1:In the writer’s opinion, it is easy for adults to learn English if _______.
A．they are especially talented people
B．they don’t want or need to learn too much
C．they have to spend a lot of time on it
D．they have a chance to go abroad
小題2:The writer believes that if you want to be good at a foreign language, you will probably _______.
A．forget your own goals
B．become a talented language learner
C．get tired of learning it
D．reach your learning goal
小題3:The best title of this passage would be _______.
A．Easy Language Learning B．Hard Language Learning
C．Fluency in a Foreign Language D．A way of Language Learning

It's important to learn about protecting our environment. Here is a 5R rule for us:
1．Reduce
If you want to reduce waste, you should use things wisely. Millions of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don't know what to do with the waste in big cities. So it is necessary to reduce the waste
2．Reuse
You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. With a family, you may pass on such clothes to younger brothers or sisters.
3. Recycle
Bottles, cans and paper can easily be recycled. By doing so, we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat（壓平）and melted（融化）and the melted things are made for new coke cans.
4．Recover
When you buy a box of apples, there may be a few rotten（腐爛的）apples, You have two choices: one is to throw the whole apple away, or you could cut off the rotten parts and eat the good parts. In this way, you are recovering the eatable parts of food.
5. Repair
If one of the legs of your table is broken, you can repair it instead of throwing it away. If you want to change for better ones, It is better for you to sell the old things or give them to other people who can use them after doing some repair. It is true that North America is a "throw－away" society(社會).But the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.
小題1:_______can be recycled.
A．Only hard things B．Many thingsC．Few soft thingsD．A11 things
小題2:The "recover' rule mainly requires us_______.
A．to throw waste things awayB．to cover waste things with earth
C．to get back the useful partsD．to throw the whole things away
小題3:We can infer（推斷）that the writer of this passage may live in_______．
A．ChinaB．JapanC．AustraliaD．America
小題4:Which of the following is true?
A．We will have no resources（資源）of nature unless we can do with the waste.
B．Recycling is the best way to save resources.
C．If we waste less, we can save more resources of nature
D．More things are wasted in developed countries than in developing ones.
