20套雅思阅读模拟题下载—Search begins for 'Earth' beyond solar system1. A European spacecraft took off today to spearhead the search for another "Earth" among the . The Corot space telescope blasted off aboard a Russian Soyuz rocket from the Baikonur cosmodrome in Kazakhstan shortly after . Corot, short for convection rotation and planetary transits, is the first instrument capable of finding small rocky planets beyond the solar system. Any such planet situated in the right orbit stands a good chance of having liquid water on its surface, and quite possibly life, although a leading scientist involved in the project said it was unlikely to find "any little green men".4. Developed by the French space agency, CNES, and partnered by the European Space Agency (ESA), Austria, Belgium, Germany, Brazil and Spain, Corot will monitor around 120,000 stars with its 27cm telescope from a polar orbit 514 miles above the Earth. Over two and a half years, it will focus on five to six different areas of the sky, measuring the brightness of about 10,000 stars every 512 . "At the present moment we are hoping to find out more about the nature of planets around stars which are potential habitats. We are looking at habitable planets, not inhabited planets. We are not going to find any little green men," Professor Ian Roxburgh, an ESA scientist who has been involved with Corot since its inception, told the BBC Radio 4 Today . Prof Roxburgh said it was hoped Corot would find "rocky planets that could develop an atmosphere and, if they are the right distance from their parent star, they could have water".7. To search for planets, the telescope will look for the dimming of starlight caused when an object passes in front of a star, known as a "transit". Although it will take more sophisticated space telescopes planned in the next 10 years to confirm the presence of an Earth-like planet with oxygen and liquid water, Corot will let scientists know where to point their . Measurements of minute changes in brightness will enable scientists to detect giant Jupiter-like gas planets as well as small rocky ones. It is the rocky planets - that could be no bigger than about twice the size of the Earth - which will cause the most excitement. Scientists expect to find between 10 and 40 of these smaller . Corot will also probe into stellar interiors by studying the acoustic waves that ripple across the surface of stars, a technique called "asteroseismology".10. The nature of the ripples allows astronomers to calculate a star's precise mass, age and chemical . "A planet passing in front of a star can be detected by the fall in light from that star. Small oscillations of the star also produce changes in the light emitted, which reveal what the star is made of and how they are structured internally. This data will provide a major boost to our understanding of how stars form and evolve," Prof Roxburgh . Since the discovery in 1995 of the first "exoplanet" - a planet orbiting a star other than the Sun - more than 200 others have been found by ground-based . Until now the usual method of finding exoplanets has been to detect the "wobble" their gravity imparts on parent stars. But only giant gaseous planets bigger than Jupiter can be found this way, and they are unlikely to harbour . In the 2010s, ESA plans to launch Darwin, a fleet of four or five interlinked space telescopes that will not only spot small rocky planets, but analyse their atmospheres for signs of biological . At around the same time, the US space agency, Nasa, will launch Terrestrial Planet Finder, another space telescope designed to locate Earth-like planets.(615 words)Choose the appropriate letter from A-D for question . Corot is an instrument which(A) can help to search for certain planets(B) is used to find planets in the orbit(C) can locate planets with human beings(D) can spot any planets with the following statements agree with the information given in the reading passage?

说到机考可能很多烤鸭都觉得头大，会没有笔试的在答题上顺手。但是机考不可逆的必将成为未来雅思考试形式，一起来了解一下雅思机考和笔试考试异同点有哪些吧。相同点：雅思听力机考和笔试用到的题库全部相同，因此考试难度、考试风格、考试内容、考试题型和常见考点不会有任何的变化。不同点：最终答题的方式明显是不一样的。在听力机考中，没有了笔试中的10分钟写答案的时间，只有两分钟的计时答案修改时间。想要检查完全部的题目，2分钟是自然不行的，因此建议烤鸭们在当做题时，能够标记一下不确定的答案，这样就可以节省检查的时间。具体操作如下：做完题目1 之后，题目框会由黑色变成蓝色，数字1下面会出现下划线，点击左边的review，方形的题目框会变成圆形。另外在雅思机考里，已经把笔试中的读例子音频取消，因此当考生看题的时间会进一步缩短。

目前真正意义的雅思机考软件只有一款，那就是匹克雅思机考软件，里面和真实雅思机考一样的，里面包含雅思4-13册真题集。听力可以输入答案、阅读有高亮功能、填空题可以复制原文的单词和句子，和真正的机考一样。

拿到真题的时候，记住留出最新的一套官方真题在考前一到两周作为考前模拟。模拟时需要按照正式考试的时间严格计时，同时配合使用答题卡，提前适应考试模式。答题卡在真题后面都有配套。做完考前模拟，如果还有精力，就抽空看看考前预测。
