语 篇 提 能阅读理解APicture our solar system. In the centre, theres our star, the sun. Orbiting the sun are eight planets, including Earth. But what about planets outside our solar system?About 15 years ago, scientists developed the tools to detect these “exoplanets”. Since then, theyve spotted about 450. Most of the findings include one, two or three enormous gasfilled planets orbiting a star.But on August 24, 2010, a group of European scientists announced an unusual discovery. They say theyve identified a solar system thats similar to ours. It consists of as many as seven planets orbiting a sunlike star. The star is over 100 lightyears away from us.The five planets that the scientists are most certain about are large up to 25 times the size of Earth. According to Christophe Lovis, one of the scientists behind the finding, these five planets are similar to Neptune (海王星). “Theyre made mainly of rocks and ice，” he said. “Theyre probably not suitable for people to live in.”There are also signs of two more planets. One is thought to be similar to Saturn (土星). The other may be the smallest exoplanet ever spotted. Its only slightly larger than Earth. Because its so close to its star, the small planet takes just over a day to orbit it.Spotting faraway planets is challenging. The blazing light given off by the star they orbit makes the planets hard to see. That is why we cannot yet be 100% sure about these seven planets. The scientists havent actually seen them. Instead, they used a powerful telescope to study the star for six years. The star gave the scientists clues about the planets that orbit it.According to Alan Boss, a scientist who wasnt involved with the study, this method is best for “finding the big guys”. But, he said, the discovery shows spotting smaller planets is also possible.“The really nice thing about finding systems like this is that it shows therere many more out there，” says Boss. “Mother Nature really had fun making planets.”语篇解读欧洲科学家利用望远镜进行探测，观察发现了一个与太阳系相似的星系。1It is known from the passage that exoplanets _.A. are planets orbiting stars other than the sunB. refer to all the planets orbiting the sunC. are all stars outside our solar systemD. include all the planets ever spotted in the universe答案与解析C细节理解题。根据第一段的“In the centre, theres our star, the sun. Orbiting the sun are eight planets, including Earth. But what about planets outside our solar system？”和第二段首句可推断， exoplanets是指太阳系以外的行星，故选C项。2In another solar system discovered by the European scientists, _.A. the star orbited by seven planets is over 100 lightyears from the sunB. all the seven planets are much larger than our earthC. none of the seven planets is suitable for people to live inD. five planets are made mainly of rocks and ice答案与解析D细节理解题。第四段介绍了科学家们比较确定的五颗行星的情况，根据该段的“Theyre made mainly of rocks and ice”可以判断选D项。3We can infer from the passage that Alan Boss _.A. has always been supporting the European scientistsB. believes using a telescope to study small stars is also possibleC. thinks the European scientists discovery is a little unbelievableD. believes there must be another planet with humans living in it答案与解析B推理判断题。根据倒数第二段Boss的话可知， Boss认为这种方法是最好的，同时他认为用望远镜观察小行星也是有可能的，故选B项。4The best title for the passage should be “_”A. Research on the Solar SystemB. Difficulty in Studying Mother NatureC. Scientists Contributions to the UniverseD. A Lot like Our Solar System答案与解析D主旨大意题。文章首先介绍欧洲科学家的发现一个与太阳系相似的星系，结尾借Alan Boss之口道出了“像这样的太阳系之外的类似星系还有很多”，由此判断选D项。BFrom the first use of the rocket to carry satellites into space to the setting up of space stations, human beings have been putting great efforts into space research. And so far, we have achieved many successes. But there are still numerous tasks in front of us and we should not stop trying to progress.The international space station is an important step we should take in space exploration. It is not only helpful but also essential. It provides a proper space environment for many experiments that we have wanted to do for a long time. It is also a base for the observations of the earth and the universe. It could also be an important base for later travel to the Moon and Mars. In a word, if we want to explore space more, the first thing we should do is to set up a space station.As the space station costs a lot of money, it is hard for one country alone to establish one. The USA seems to be the only country that has the ability to build a space station alone, and it has tried to do so, but not very successful. So it aggregated many other countries to work on it together. Though it is still extremely expensive, it is much cheaper than doing it alone. It is really a job that needs everyones effort and will benefit everyone.But even so, the funds needed are still a big problem. As for the USA, it seems that it has too many things to spend its money on. Although it is the richest country in the world, it has much debt every year. It has to make arrangements about its finance, and try to find a balance in all these issues.5What is the authors attitude towards building and developing the international space station?A. Supportive. B. Doubtful.C. Critical. D. Dissatisfied.答案与解析A作者态度题。根据第一段中的“we should not stop trying to progress”和文中作者介绍国际空间站的重要性可知，作者对建设国际空间站持支持态度。6From Paragraph 2 we learn that _.A. the necessity of building the international space station is not realized nowB. many experiments have been done in the international space stationC. the international space station is necessary for people to explore space moreD. people have travelled to Mars from the international space station答案与解析C细节理解题。根据第二段中的“In a word, if we want to explore space more, the first thing we should do is to set up a space station
