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.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. |

| 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 |

Travelling is one of the most important activities and people have been interested in it for many years. Modern traffic develops fast, so travelling to different places has become much faster than before. Staying healthy while travelling can make your trip happier.

Many years ago, two friends, Mike and Jim, were walking through the desert. Somehow they began to quarrel (争吵 ) about small matters. Suddenly, Mike hit Jim in the face. Jim was hurt, but he said nothing. He just wrote in the sand: Today my best friend hit me in the face. They kept on walking, and at last, they found a river. So they decided to take a bath. Suddenly, Jim got stuck in the mire (陷在泥里 ). At that moment, Mike saved him. After Jim felt better, he wrote on a stone: Today my best friend saved my life.
Mike saw this, and asked, “After I hurt you, you wrote in the sand. After I saved you, you wrote on a stone. Why?”
Jim answered, “When someone hurts us, we should write it down in sand. Thus wind of forgiveness (宽恕 ) can blow it away. But, when someone does something good for us, we must engrave (铭刻) it in stone, then no wind can ever blow it away.”When did the story happen? _____________________________

Many scientists find that colours can change people’s feelings. It’s very interesting. Some colours can make people feel relaxed，and some colours can make people feel nervous. Now，this kind of knowledge is being used in many places. For example，school walls are always painted green because green makes students feel relaxed. It is also good for the students’ eyes. Some books are also green or light blue for the same reason. Restaurant owners not only have to know how to make food，but also have to know how to make money. Here are some things they’ve learned from scientific studies. The colour red makes people hungry. Many fast food restaurants have red furniture or walls. Soft colours like pink and light blue make people feel relaxed，so they spend more time eating. Loud music may be nice at first，but it soon makes people want to leave. Hard seats also make customers want to eat quickly and leave. Many restaurants，especially fast food restaurants，use this knowledge to make customers eat faster.How does the colour green make the students feel？
