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 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 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.
【小题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. |

Our earth is in trouble. Our drinking water is becoming dirtier, and the air is not as clean as before. People and factories are polluting the air, rivers and lakes and seas. You may think that there is mothing you can do to help. That’s not true. There are many things you can do to help the earth.
Cars burn gasoline. This will produce a lot of CO2 into the air. Some people believe that too much CO2 is making the earth warmer than ever. They think CO2 thins the clouds above us. The clouds keep us away from the strongest sunlight. So try to walk, ride a bike or take a bus. And if you drive a car, drive at a steady speed. This can save some gasoline.
The biggest energy use at home is for keeping warm and cool. So turn the air conditioner off when you don’t need to use it. Use lights that save energy.
Use fewer things that cannot be used again. When you buy something, consider those made from things that can be used again first.
（1）要用大量的水来洗澡沐浴。In one week an American family uses as much water for showers as a person drinks in three years! Buy a waterworks that uses less water, or take shorter showers. This can cut the use of water.

Some people believe that classes, teachers and school buildings will no longer be necessary in the near future because of the Internet and other new technology. Perhaps this will be true one day, but if the world has no schools, I can't imagine how our society will be. In fact, we should learn how to use new technology to make schools better. We should invent a new kind of school connected to libraries, museums, science centers, labs and even companies. Technological companies should create learning programs for schools. Scientists could give talks through the Internet. TV networks and local stations could develop programs about things students are studying in school. Labs could set up websites to show new technology, so students could see it on the Internet.
Is this a dream? No. There have been many cities where this is beginning to happen. Here the whole city is connected to the Internet, and learning can take place at home, at school, and in the office. Businesses provide programs for the schools and the society. The schools provide computer labs for people without their own computers at home. Because everyone can go on the Internet, older people use it as much as younger ones, and everyone can visit faraway libraries and museums as easily as nearby ones. How will this new thing of school change the usual way of learning? It is a little early to be sure, but it is very exciting to think about it. Technology will change the way we learn; schools will change as well; and we will learn something from the Internet.
【小题1】Who thinks that students won’t have to go to school?
| A．Everyone. | B．The writer. | C．Some people. | D．The teachers. |
| A．A school with many new computers. | B．A school with many new students. |
| C．A school with many new teachers. | D．A school connected to the Internet. |
| A．schools are still necessary | B．more schools should be built |
| C．there should be fewer schools | D．more computers are needed in schools |
| A．Because whole city is connected to the Internet. |
| B．Because everyone can go on the Internet. |
| C．Because getting online is very easy. |
| D．Because Scientists could give talks through the Internet. |
| A．Technology will change our way of learning. |
| B．If you are a student, you can set up websites to show new technology. |
| C．The schools provide computer labs for those who have no personal computers. |
| D．On the Internet, you can visit another city's libraries as easily as the people there. |

When an animal helps another animal, it usually gets something valuable in return. For a long time, many scientists thought that only people could act generously just because it feels good.
However, a new study in Germany suggests that chimpanzees (黑猩猩)also do good things for no real reason. And so do children who are as young as 18 months of age. Maybe it is because humans and chimpanzees share an ancestor(祖先) about 6 million years ago.
People and chimpanzees appear to develop such features(特征) without any other training, says Warneken, a scientist in Germany. Warneken and his partners worked on adult chimpanzees that live on an island in the African country of Uganda. They also worked with 18-month-old children in Germany. The researchers performed three experiments on the adult chimpanzees and two experiments on the kids. In the first animal experiment，a person tried to reach his arm into a cage to get a stick，but he couldn’t reach it. A chimpanzee was in the cage，and it could reach the stick if it wanted to.
Thirty-six chimpanzees took part in this experiment one by one, and no chimpanzee saw what the other chimpanzees had done. Even though the animals hadn’t met the person before, they usually took the stick and gave it to the person. What’s more, they did this whether or not the person offered them bananas as a reward. In a similar experiment, 36 children acted in a similar way. They helped the person reach the stick, whether or not they were offered toys for their help.
Researchers did other experiments on chimpanzees and babies. No rewards were offered in either experiment. And still, both the chimpanzees and children went out of their way to help. Still, the new study is different from earlier findings. Researchers have found that chimpanzees don’t give rewards of food to other chimpanzees, even if it costs them nothing to be generous.
【小题1】Warneken and his partners worked with ________.
| A．young chimpanzee that live on an island |
| B．18-month-old children who live in Germany |
| C．kids who are living with adult chimpanzees |
| D．adult chimpanzees that live on the African mountain |
| A．people also share information for good reason |
| B．children know something at the age of 18 months |
| C．chimpanzees do good things for no real reason, too |
| D．humans should develop their abilities 6 million years ago |
| A．Thirty-six chimpanzees joined in this experiment one by one |
| B．No chimpanzee saw what the other chimpanzees had done |
| C．The animals hadn’t met the person before the experiments |
| D．Chimpanzee gave the person the stick in order to get a reward |
| A．both chimpanzees and children can find their way to help others |
| B．chimpanzees will reward good food to other chimpanzees |
| C．children is more generous than chimpanzees in some ways |

What would happen if you tried to blow a soap bubble in freezing weather? Would it freeze solid(固体) and fall to the ground? Would you have to hit it to break it? These questions happened to me on a cold winter day. It was too cold to play in the snow, but it was a perfect time to experiment with blowing frozen bubbles.
To blow frozen bubbles, I used dishwashing soap and a drop of glycerin（甘油） to make it even better. I chose a place out of the wind, and blew bubbles the same way I always do. I watched to see what would happen. Here’s what I learned.
If the temperature is low enough, the skin of the bubbles frosts over (结霜), becoming cloudy instead of clear. And what about those rainbow swirls（旋转） you see in soap bubbles? The rainbow colors stay even when the bubbles frost, but they don’t swirl anymore. The bubbles still stay in the air. They don’t fall to the ground any faster than they would on a warm summer day.
When these frozen bubbles break, they don’t turn into small water drops as summer bubbles do. They turn into flashing rainbow confetti（碎屑） and move slowly to the ground. Sometimes a frozen bubble will roll across the snow without breaking. If nothing disturbs the bubble, it may stay there for a long time. Sometimes I could catch a bubble and hold it until the heat of my hand made it pop.
I learned another thing about blowing frozen bubbles. It’s so interesting that I want to try it again next year.
【小题1】It is the perfect time to blow frozen bubbles on a ___________day.
| A．cold winter | B．warm spring | C．hot summer | D．sunny autumn |
| A．they make a big sound | B．they turn into small drops |
| C．they fall to the ground like rain | D．they become rainbow confetti |
| A．to learn how to do a science experiment |
| B．to show the experiment of blowing frozen bubbles |
| C．to discover games that are fun to play in the snow |
| D．to invent a new kind of soap that makes stronger bubbles |

Which day is the most important for you? Your birthday, the first day of your work or the day you win a prize.

On that day, relatives(亲戚) and friends come to bless the baby. In northern part of China, like Inner Mongolia, a child’s 12th birthday is a big day. This is when a child becomes a teenager. Eighteen is another important age, which means you must be responsible(负责任的) for what you have done in laws. As for adults, maybe the anniversary of their marriage(结婚周年庆) is the most important.
