In September2010, 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 the 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 about220 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 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. ( )1. What did scientists find in September 2010? A. A planet with water. B. A planet different from the earth. C. A planet without life. D. A planet near the earth. ( )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 ( )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 ( )4. Which of the following is the best title for the passage above? A. Gliese 581g,a Likely Living Planet. B. Gliese 581g and Its Surface. C. Gliese 581g and Its Star. D. Gliese 581g and Radiation. 五、阅读短文，完成表格 (每空一词) Most parts of our Earth have much water, fresh air and lots of land to plant crops. But it is becoming more and more crowded and polluted. People living on Earth suffer from environment pollution. Man has been polluting Earth. Air pollution is still the most serious. It's bad for all living things in the world, but it is not the only one kind of pollution. Polluted water kills our fish and makes our drinking water dirty. In cities, it is so noisy that it makes us angry more easily. More and more people are thinking about living on Mars in the future. Mars is the fourth planet from the sun. People have imagined living on Mars since the beginning of the twentieth century.However, people still need to solve many problems before we could live on Mars. First of all, Mars can be very hot but sometimes it can be very cold. It can be low as-133℃. It is impossible for humans to survive in this kind of low temperature. Secondly, water is a problem. About3 billion years ago, there was water on Mars, but it had become ice. So at present, Earth is our ideal home. We must take care of it. That means we must keep the land,water and air clean. And we must control population growth at the same time. The planets The living conditions Earth Advantages Earth is beautiful and it has much water,(1)______ air and lots of land to plant crops.

Even though today, very few people get the chance to be an astronaut, about 30 people per year. This is mainly because of the expense. It costs m 1 of dollars to train and send astronauts into space. Very few countries can a 2 this. American businessman Dannis Tito paid 20,000,000 US dollars to the Russian Space Agency(俄罗斯宇航局) to be taken into space. He visited the International Space Station. His trip made him the f 3 ever space tourist. He spent most of the time t 4 photos and looking at the Earth. After 1 5 safely back on Earth, Mr Tito thought the trip was w 6 the money. The only d 7 he had was walking but this is normal for anyone who's been in zero gravity. Mr Tito received t 8 before he left. He also helped to prepare food for the others when in space. They told him what to do and where he was a 9 to go. The money he gave the Russians was p 10 for 20% of their annual budget(年度预算). If we want to see men on Mars and other planets, we may need rich people to help us. 七、书面表达 ( Elective Course Subject Photography ● taking photos Gardening ● growing flowers Teacher a young reporter an old gardener Time &Place ●4:00p. m.—4:45p. m.● City Park 4:00 p. m.—4:45 p. m.School's garden Tip take cameras tools offered by school )假如你是阳光中学的李华，每周五下午你校开设校本必修课(required course)与选修课(elective course),请介绍必修课 Travel of Science, 另外根据个人具体情况选择一门选修课并说明理由；同时，对你所选择的课程提出建议。 Required course Subject Travel of science ● introducing scientists and inventions Teacher a professor Time &Place ● 2:30p. m.—3:15p. m.● school hall Tip take notebooks and pens 要求： 1.所写内容必须包括必修课及一门选修课的所有信息； 2.对你所选择的一门选修课说明理由，并对其提出建议； 3.文章不少于 90词，开头和结尾已给出，不计入总词数； 4.语意通顺，意思连贯，条理清楚，书写规范； 5.文中不得出现真实的姓名、校名等信息。 Every Friday afternoon, our school offers required and elective courses. 一、单项选择 1.

I'm Li Hua from Sunshine Middle School. Every Friday afternoon, our school offers required courses and elective courses. The required course is Travel of Science. It is from 2:30 p. m. to 3:15 p. m. in the school hall. A professor will introduce some famous scientists and their great inventions. We are advised to take notebooks and pens to record useful information. As for the elective course, I choose Painting. I love art and I think painting can help me relax and express my feelings. It also allows me to show my creativity. However, I have some suggestions for this course. I hope we can have more outdoor painting classes to get close to nature and find more inspiration. Also, the teacher could give us more individual guidance so that we can improve our painting skills more effectively. I believe these courses will bring us a lot of fun and knowledge. 学科网（北京）股份有限公司 $$
