Do you play a musical instrument? If so, you may be getting smarter. A recent study shows that taking music lessons can raise a person’s IQ.
Scientists studied 132 children in Canadian schools. At the beginning of the school year, these children took an IQ test. Then they were divided into four groups. One group took singing lessons. Another group took weekly piano lessons. The third group took classes in drams(戲劇). And the last group did no special activities at all.
At the end of the school year, the 132 children took an IQ test again. In all four groups, the average score went up. However, the piano players’IQs went up 7.0 points on average. The average increase for the other three groups was only 4.3 points.
The researchers say that the difference is small and it may not result in better grades for the piano players. However, they still consider the results important. Learning an instrument helps kids becomes better at concentrating and at memorizing things. Therefore, the researchers say, it may be good for brain development in young people.
If you have a chance to learn to play a musical instrument, never miss it. Remember it can make you smarter.

After spending years searching for a planet with life, scientists may have found one. In September 2010, a team of US scientists discovered an Earth-sized planet called Gliese 581g. It has a surface temperature neither too hot nor too cold for liquid（液態）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 spacecraft 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 sight 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（望遠鏡）towards the planet and search for radiation（放射）. By studying the radiation, scientists would find out about the chemicals（化學物質）around the planet and discover it Gliese 581g has an atmosphere. If it has one, studying the atmosphere would give us a good idea if 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 star	B．moves around the earth
C．is as far away from us as the moon	D．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 Planet	B．Gliese 581, a Likely Living Planet
C．Gliese 581g and Its Star	D．Gliese 581g and Radiation

What will the house of the future look like? Could it have gardens on its walls, or a pool with fish for dinner? Architects believe that they are all possibilities. The only thing for sure is that the houses will be as green as possible.
The tree house
Many architects in the world would like to build a “tree house.” Like a leaf, the surface of the house collects sunlight during the day. The energy can be used to heat water, produce electricity, and even create fresh air for the home. The “root” (根) of the house is deep under the ground. It uses the soil (土壤) to the home’s temperature.
The Lizard house
Like a lizard (蜥蜴), changing color with the weather is the most important design of a lizard house. When it’s in the bright sun, the cover of the house will turn dark to protect it from strong heat. During dark days, it turns white and takes in as much light and heat as possible to produce energy.
Meals at home
This design is perhaps as much about the future of food production as architecture (建筑風格). It has gardens on the outside wall of the house. People can plant tomatoes, carrots and green tea on them. So every day in the morning, you just need to walk outside and collect your meals.
Learning from the past
Looking to the future isn’t the only way to be green. Sometimes, ancient techniques (古老的技術) can also help cut down energy use. For example, a chimney (煙囪) can be a useful air conditioner because it is easier of hot air to flow out at the chimney.
小題1:What is the best title (標題) of the passage?
A. Green house of the future.
b. The greener, the better.
C. How to build green houses.
D. Changes of the houses.
小題2:We can heat water, produce electricity or create fresh air for the home            .
A. with the root of a leaf.
b. with the energy from sunlight.
C. with the soil under the ground
D. with gardens on its walls.
小題3:What will happen to the cover of the lizard house when it’s in the bright sun?
A. It will take in light.
b. It will produce energy.
C. It will turn dark.
D. It will turn white.
小題4:The passage seems to tell us that meals at home in the future            .
A. will be more delicious.
b. need more cooks.
C. cost as much as possible.
D. will be greener.
小題5:A chimney can be a useful air conditioner but it used to cause          .
A. pollution.   b. accident.     C. noise.      D. techniques.

One day when some government officials were rebuilding a house, they found a mouse hole in a corner and used smoke to make the mice inside the hole come out. A while later they saw mice running out, one after another，but they saw two mice didn’t run away immediately. It seemed that one was trying to bite(咬) the tail of the other.

Tony: These days, the word “clone” has appeared very often in the newspapers. Do you know its meaning?
Lana: I read a report. It said that Dr. Ian Wilmut successfully cloned a lamb* named Dolly from a grown-up sheep. So people call him the “father” of Dolly.
Tony: In fact, the word “clone” means to produce the “same” animal by taking cells* from a
grown-up one. I think, if we know how to do cloning, we need only to keep a small number
of sheep, cows or horses.
Lana: What’s more, these days some people even want to clone humans. They have asked: Can we
clone ourselves?
Tony: It seems interesting. But do you think it possible to do that?
Lana: No, impossible! First, I think we cannot clone a dead person, because the cells in his body are dead already.
Tony: Then can we clone a living person?
Lana: Again no! You might clone yourself one after another, but it is only a copy, not a real you. It is only something, not a “human”.
Tony: Well, you mean that it is not a real human.
Lana: True enough! I think Dr. Wilmut would most like to make better animals, and it has nothing to do with human cloning.
小題1:The word “clone” means_________________.
復制 B 克隆 C 抄襲   D 制造

Now satellites(衛星)are helping to forecast(預報)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 station. So meteorologists(氣象專家)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 meteor- ologists compare(比較)them with earlier ones. Peerhaps they may find that the clouds have changed during the last few hours .This may mean 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 3 or 5 days. Soon,perhaps , they may be ablet to forecast the weather for a week or more ahead(提前)
小題1:Satellites travel__________.
A in space           B in the atmosphere
C above the ground    D above space
小題2:Why do we use the weather satellites to take pictures of the atmosphere? Because___________.
A the weather satellites can do it easily
B clouds form there
C the weather forms there
D the pictures can forecast the weather
小題3: Meteorologists forecast the weather________.
A when they have received satellite pictures
B after they have compared new satellite pictures with earlier ones
C before they receive satellite pictures
D while they study satellite pictures
小題4:Maybe we’ll soon be able to forecast the weather for _______.
A one day   B two days C five days   D seven days or even longer
小題5:The main idea of this passage is that satellite are now used    in______.

Dolphins are our friends. They can use tools to solve problems although they don't have hands. For example, scientists have ever found that a dolphin can make a shy eel(鰻魚) come out of its hole with a dead fish.
Dolphins use different sounds to exchange information with each other. Scientists in Hawaii have developed a sign language to give instructions to dolphins, and the results are amazing. They find that dolphins not only understand the meaning of individual (個別的) words, but also understand the importance of word order in a sentence.
Most animals enjoy playing — but dolphins seem to like making their games as challenging as possible. On a beautiful day in 1997, scientists at a beach watched a little dog going into the sea and swimming towards the dolphins. To their surprise, the dolphins came up to the dog and then started throwing it into the air. The dog seemed to enjoy the "game" and continued playing with the dolphins for more than an hour.
Dolphins live in a very different world from ours, but they are very good at our "IQ tests” . For example, they will jump out of the water when they hear a whistle (口哨) noise. They do this because they will get a fish as a prize.
There is still much to learn about these cute problem-solvers, but it is certain that watching a dolphin show is fun.
根據短文內容，選擇最佳答案。（5分）
小題1: What can a dolphin use to make an eel come out of its hole?
