雅思阅读全真练习系列（十一）

　　2. Scientists are trying to find out about the planets that can be inhabited.

　　3. BBC Radio 4 recently focuses on the broadcasting of Corot.

　　4. Passing objects might cause a fall in light.

　　5. Corot can tell whether there is another Earth-like planet.

　　Based on your reading of the passage, complete the sentences below with words taken from the passage. Use NO MORE THAN THREE WORDS for each answer.

　　With measurements, scientists will be able to search for some gaseous and rocky planets. They will be extremely excited if they can discover some small 6. __________, the expected number of which could be up to 7. __________ .

　　Corot will enable scientists to study the 8. __________ of stars. In this way, a star’s mass, age and chemical composition can be calculated.

　　According to Prof Roxburgh, changes in light can be caused by passing planets or star 9. __________. The related statistics can gain us a better 10. __________ of the star formation and evolvement.

　　Observatories have found many exoplanets, which are 11. __________ other stars than the Sun. The common way used in finding exoplanets can only detect huge gas planets, which do not 12. ___________ .

　　With the launching of Darwin, astronomers will be able to analyse whether those rocky planets have 13. __________ for life.

　　Answer keys:

　　1. 答案：A (第3段第1句：Corot, short for convection rotation and planetary transits, is the first instrument capable of

　　finding small rocky planets beyond the solar system. A项中的certain planets指small rocky planets beyond the solar system.)

　　2. 答案：TRUE (第5段第1、2句： 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. 问题中的“that can

　　be inhabited”意思就是inhabitable.)

　　3. 答案：NOT GIVEN (文中没有提及该信息。)

　　4. 答案：TRUE (第7段第1句：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".)

　　5. 答案：FASLE (第7段第2、3句：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 lenses. )

　　6. 答案：rocky planets (第8段第2句：It is the rocky planets - that could be no bigger than about twice the size of the

　　Earth - which will cause the most excitement.)

　　7. 答案：40 (第8段第3句：Scientists expect to find between 10 and 40 of these smaller planets.问题中短语“up to”的意

　　思是“达到，高达”，所以应该选择最高的数字40。)

　　8. 答案：interiors (第9段第1句： Corot will also probe into stellar interiors by studying the acoustic waves that ripple

　　across the surface of stars, a technique called "asteroseismology". 单词"probe”的词义是“探查，探索”。)

　　9. 答案：oscillations (第11段第2句：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.)

　　10. 答案：understanding (第11段第3句：This data will provide a major boost to our understanding of how stars form

　　and evolve.)

　　11. 答案：orbiting (第12段第1句：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 observatories.)

　　12. 答案：harbour life (第13段：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 life.)

　　13. 答案：atmospheres (第14段：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 activity.)
