22、 It was a discovery that could change science. “We hit_the_jackpot here，” said scientist Guillem AngladaEscude about the discovery of the planet more or less like Earth that is orbiting Proxima Centauri (半人马座比邻星), the star nearest to our solar system.What do we know about this exciting new Earth? We
23、ll, Proxima b, or “Earth ” as you could call it, is a little bigger than our Earth, and its revolution only takes 11 days. Also, since it is so much closer to its red dwarf star than Earth to the sun, the sky there is orange without any blue at all, creating a forever sunset effect. But there are a
24、lot of questions about life forms that could live on this new planet.The discovery of the planet made the Chicago Tribune newspaper wonder if anyone had seen or heard of the USs space postcards from its Pioneer 10 and Pioneer 11 spaceship, which were pictures of a man and a woman, along with diagram
25、s of the solar system. If there are aliens (外星人) on Proxima b, they would have found images showing the incredible diversity of Earth.Aliens might also have heard the message from former US President Jimmy Carter：“This is a present from a small distant world . We are attempting to survive our time s
26、o we may live into yours. We hope someday, having solved the problems we face, to join a community of galactic (银河的) civilizations.

27、 if it has an atmosphere at first, we would need to invent a way to get there in less than 78,000 years it would take at 36,000 mph (about 57,900 km/h)语篇解读：本文是一篇科普说明文。科学家在太空中发现一颗大小与地球有几分相似的行星。这颗类地行星绕着半人马座比邻星(距我们太阳系最近的恒星)进行轨道运动。8What does the underlined phrase “hit the jackpot” probably mean?AMake a
28、bet.BTake a risk.CSucceed by chance. DMiss the boat.解析：选C词义猜测题。根据第一段中的第一、二句及下文内容可知，科学家偶然发现了一颗类似地球的行星，这是一项能够改变科学的新发现。对于发现这颗行星的科学家来说，他们好像是中头奖了。hit the jackpot意为“中头奖”，在此可指“意外成功”。9What does the author say about Proxima b?AIt has a shorter period of revolution.BIt is of the similar weight to Earth.CIt is
29、 a newlyfound planet in the solar system.DIts sky looks orange for being closer to the sun.解析：选A推理判断题。根据第二段中的“its revolution only takes 11 days”可知，比邻星b的公转周期仅有11天。相对于地球的公转周期(约365天)而言，比邻星b的公转周期要短得多。10What do President Jimmy Carters words suggest?AHumans eagerness to meet creatures from outer space.BTh
30、e great progress made in space exploration.CThe best wishes for Americas space program.DHumans determination to explore outer space.解析：选D推理判断题。根据第四段的内容和其中的关键信息“we may live into yours”“to join”“our determination”可知，美国前总统吉米卡特给外星人的留言内容传递了人类探索外太空的决心。11What seems to be the major problem for our visit to
31、Proxima b?AThe lack of air on the planet.BToo great a distance from us.CUncertainty about life forms there.DThe glaring sunlight all years.解析：选B推理判断题。根据最后一段可知，如果人类想要探访比邻星b，需要寻找一种更快的抵达方式。人类以3.6万英里每小时(约5.79万千米/时)的速度需要7.8万年才能到达那里。由此可推知，人类探索比邻星b的最大问题是比邻星b距离我们太远。tips 利用上下文语境猜测词义在文章中，任何一个单词都不是孤立存在的，它总要通过上
32、下文和其他单词有着紧密的联系(如定义、重述、举例、近义词和反义词等)，通过这些联系可以猜测出单词的意思。有时作者在阐述某人、某物或某一现象的特点时，先是一般地或概括性地说一下，然后再作具体的说明或解释；或者反过来，先作具体的阐述，然后再进行归纳、总结。如果读者能抓住作者的思路就能从那些具体说明、解释或归纳中找出猜词的线索来。做词义猜测题，要学会“顺藤摸瓜”和“上下取证”，即利用上下文提供的情景和线索，通过对平行结构或对应结构中的同义词、反义词等进行推断，再结合我们的生活常识和社会经验进行符合逻辑的综合分析，并依此来推测词义，切忌脱离上下文盲目猜测。例如上文C篇阅读中的第8题，根据“hit the jackpot”的上下文可知，科学家偶然发现了一颗类似地球的行星，这是一项能够改变科学的新发现。对于发现这颗行星的科学家来说，他们好像是中头奖了。hit the jackpot意为“中头奖”，在此可指“意外成功”。
