9、ts a star 500 light years from Earth.A very good telescope was not even required；they found the planet using several small telescopes much like those used by amateur astronomers.The new planet is named TrES2 because it is the second such planet found by scientists working on the TransAtlantic Exopla
10、net Survey(TrES) It is a transiting planet(凌日行星)，meaning it can be seen transiting，or moving，across the star it orbits.Ted Dunham，an instrument scientist at Arizonas Lowell Observatory，says transiting planets are special because researchers can answer a lot of questions about them.All it takes is so

14、 that to find smaller planets like Earth or Venus，scientists need to send instruments on a mission(使命 ) to space.NASA scientists are planning one called the Kepler Mission，which could begin in two years.TrES2 is in the part of the sky that the Kepler Mission will study.Since astronomers already know

20、e back 3.that he is a beggar 4.Who he will invite5Where we will hold the basketball match.1.D 句意为：任何帮助解救落水女孩的人都值得称赞 。此 题考查主语从句的用法。B、C 两项容易排除掉； A 项仅表示疑问概念；whoeveranyone who。2B 第一空为主语从句，从句本身缺少主 语，故而用 what；第二空为表语从句，从句中不缺少任何成分，所以用 that。3B 从结构上看，该句为主 语从句，从句本身不缺少任何成分，所以用 that。4B 考查宾语从句。宾语从句用 陈述语序，故排除 A、D
21、两项；由 asked 可知从句应用一般过去时，排除 C 项。5B 此句的结构较为复杂，我 们可以把句子还原成“It is true _ it will be as hot as in the summer here_ the rain stops.”，这样我们能够较为明了地判定缺少的成分。6A 从句充当主语时，谓语动词 用单数；当从句中不缺少任何成分 时，用 that 引导。7B 主语从句中缺少 do 的宾语，所以用 what 引导从句。8D it 充当形式主语，真正的主语是“the two sides.peace”。9A 第一个 that 引导一个主语从句；第二个 that 是个指示代词，在
22、主语从句中作主语；第三个 that 是个关系代 词，引导一个定语从句，修 饰 all。句意为：据说这就是他说的话。10B 根据句意可判定从句表达一个一般疑问概念，在主语从句中只能用 whether，不能用 if。11D what 可连接表语从句，并作表语从句的主语。12D 从结构上看，该句为 主语从句，从句本身不缺少任何成分，所以用 that。13A 主语从句中缺少宾语(get 与 have 的宾语)，所以两空都用 what。14A how 表示方式，在从句中作状语；what 代替事物，在从句中作主语。15C 句意为：任何犯错误的人都必须改正。此 时 whoeveranyone who。.1.
23、B 标题归纳题。文章一开 头就点明了主题：一组国际 天文学家发现了一颗比木星稍大的行星，然后逐一介绍了有关 这颗行星的其他方面，故 B 项为最佳答案。而 A 项太宽泛；C项只是文章中的一个细节；D 项则完全偏离了方向。2D 细节理解题。根据原文第三段最后一句可知 选 D。3A 词义猜测题。联系上下文即可看出 这句话中的 them 是指主句中提到的 transiting planets。4D 细节理解题。根据原文倒数第四段的 “You would feel a little more than twice as heavy as on Earth if you were on TrES2.”进行
24、计算：562112， 结合 a little more than 可知 D 项正确。. 参考范文With the global environment getting worse and the enhancement of peoples sense of environmental protection，there is a trend that more people choose the lowcarbon lifestyle which stands for health，nature and safety.It means living at a lower cost，that i
