雅思阅读练习及答案：

1. A European spacecraft took off today tospearhead the search for another "Earth" among thestars.

2. The Corot space telescope blasted off aboarda Russian Soyuz rocket from the Baikonurcosmodrome in Kazakhstan shortly after 2.20pm.

3. Corot, short for convection rotation andplanetary transits, is the first instrument capableof finding small rocky planets beyond the solarsystem. Any such planet situated in the right orbit stands a good chance of having liquidwater on its surface, and quite possibly life, although a leading scientist involved in the projectsaid it was unlikely to find "any little green men".

4. Developed by the French space agency, CNES, and partnered by the European SpaceAgency (ESA), Austria, Belgium, Germany, Brazil and Spain, Corot will monitor around 120,000stars with its 27cm telescope from a polar orbit 514 miles above the Earth. Over two and a halfyears, it will focus on five to six different areas of the sky, measuring the brightness of about10,000 stars every 512 seconds.

5. "At the present moment we are hoping to find out more about the nature of planetsaround stars which are potential habitats. We are looking at habitable planets, not inhabitedplanets. We are not going to find any little green men," Professor Ian Roxburgh, an ESAscientist who has been involved with Corot since its inception, told the BBC Radio 4 Todayprogramme.

6. Prof Roxburgh said it was hoped Corot would find "rocky planets that could develop anatmosphere 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 anobject passes in front of a star, known as a "transit". Although it will take more sophisticatedspace telescopes planned in the next 10 years to confirm the presence of an Earth-like planetwith oxygen and liquid water, Corot will let scientists know where to point their lenses.

8. Measurements of minute changes in brightness will enable scientists to detect giantJupiter-like gas planets as well as small rocky ones. It is the rocky planets - that could be nobigger than about twice the size of the Earth - which will cause the most excitement. Scientistsexpect to find between 10 and 40 of these smaller planets.

9. Corot will also probe into stellar interiors by studying the acoustic waves that rippleacross the surface of stars, a technique called "asteroseismology".

10. The nature of the ripples allows astronomers to calculate a star’s precise mass, ageand chemical composition.

11. "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 thestar is made of and how they are structured internally. This data will provide a major boost toour understanding of how stars form and evolve," Prof Roxburgh said.

12. Since the discovery in 1995 of the first "exoplanet" - a planet orbiting a star other thanthe Sun - more than 200 others have been found by ground-based observatories.

13. Until now the usual method of finding exoplanets has been to detect the "wobble" theirgravity imparts on parent stars. But only giant gaseous planets bigger than Jupiter can befound this way, and they are unlikely to harbour life.

14. In the 2010s, ESA plans to launch Darwin, a fleet of four or five interlinked spacetelescopes that will not only spot small rocky planets, but analyse their atmospheres for signsof biological activity.

15. At around the same time, the US space agency, Nasa, will launch Terrestrial PlanetFinder, another space telescope designed to locate Earth-like planets.
