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.
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.

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

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

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

In 1826, a Frenchman named Niepce needed pictures for his business .But he was not a good artist .So he invented a very simple camera. He put it in a window of his house and took a picture of his garden .That was the first photo.

What is your zodiac（生肖） animal? According to the Chinese lunar calendar（农历）, 12 animals mark 12 different years. It is the basis of the Chinese zodiac. Nowadays, Chinese zodiac animals have worldwide fame and are increasingly popular among western people.
The zodiac is an important part of Chinese culture. People believe that the characteristics of a zodiac animal influence the personality of every person born in that year. For example, people born in the Year of the Tiger are considered powerful and brave.
Zodiac animals also have some social functions. When people think it is not proper to ask: “How old are you”, they may change their question to “What is your zodiac animal?” With this question, you can figure out roughly which year someone was born and the person’s age.
Zodiac animals are not special to China. Many countries share a similar zodiac culture with China. For example, in the Japanese Zodiac, a wild boar（野猪）takes the place of a pig and the Vietnamese（越南的）zodiac has a cat instead of a rabbit.
But have you ever wondered how these 12 animals were chosen to represent each year? According to legend, the Jade Emperor（玉皇大帝）invited all the animals to join him for Chinese New Year. Only 12 animals went to see him. As a reward he named a year after each one in the order they arrived. The ox would have been the first to arrive, but the rat sat on his back and jumped off just before they arrived to come in first place.

Happiness is for everyone. You don’t need to care about those people who have beautiful houses with large gardens and swimming pools or those who have nice cars and a lot of money and so on. Why? Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads at their free time.
In fact, happiness is always around you if you put your heart into it. When you are in trouble at school, your friends will help you; when you study hard at your lessons, your parents are always taking good care of your life and your health; when you get success, your friends will say congratulations to you; when you do something wrong, people around you will help you to correct it. And when you do something good to others, you will feel happy, too. All these are your happiness. If you notice a bit of them, you can see that happiness is always around you.
Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also say you are very happy, because you have something else that can’t be bought with money. When you meet with difficulties, you can say loudly you are very happy, because you have more chances to challenge(向…挑战)yourself. So you can not always say you are poor and you have bad luck. As the saying goes, life is like a revolving(旋转)door. When it closes, it also opens. If you take every chance you get, you can be a happy and lucky person.
