Unit 3 Inventors and inventions.阅读理解A space ambassador could be appointed by the United Nations to act as the first point of contact for aliens trying to communicate with Earth.Mazlan Othman, a Malaysian astrophysicist(天体物理学家), is set to be tasked with coordinating（协调） humanitys response if and when extraterrestrials（天外来客） make contact.Aliens who landed on earth and asked: “Take me to your leader” would be directed to Mrs. Othman.She will set out the details of her proposed new role at a Royal Society conference in Buckinghamshire next week.The 58-year-old is expected to tell delegates that the proposal has been prompted by the recent discovery of hundreds of planets orbiting other stars, which is thought to make the discovery of extraterrestrial life more probable than ever before.Mrs. Othman is currently head of the UNs little known Office for Outer Space Affairs (Unoosa).In a recent talk to fellow scientists, she said: “The continued search for extraterrestrial communication, by several institutes, sustains the hope that some day human-kind will receive signals from extraterrestrials.”“When we do, we should have in place a coordinated response that takes into account all the sensitivities related to the subject. The UN is a ready-made mechanism for such coordination.”Opinion is divided about how future extraterrestrial visitors should be greeted. Under the Outer Space Treaty on 1967, which Unoosa oversees, UN members agreed to protect Earth against contamination(污染) by alien species by “sterilizing” them.Mrs. Othman is understood to support a more tolerant approach.But Professor Stephen Hawking has warned that alien interlopers（闯入者） should be treated with caution.He said: “I imagine they might exist in massive ships, having used up all the resources from their home planet. The outcome for us would be much as when Christopher Columbus first landed in America, which didnt turn out very well for the Native Americans.”1.The United Nations appointed Mazlan Othman as a space ambassador_.A.to talk to fellow scientists receiving signals from extraterrestrialsB.to protect the earth against pollution by alien speciesC.to make contact with aliens trying to communicate with the earthD.to settle UN members argument about signals from extraterrestrials2.The leader whom aliens ask to be taken to will be_.A.Stephen Hawking, a British professorB.Mazlan Othman, head of the Royal SocietyC.BanKiMoon, the general secretary of the UND.Mrs.Othman, head of the UNs Office for Outer Space Affairs3.The underlined words in the ninth paragrath coule best be repalaced by ( )A. making them unable to produce childrenB.keeping them out of touch with the earhC. stopping them away from outer spaceD. makind them unable to explore space 4.What Stephen Hawking said suggests that_.A.alien invaders(侵略者) should be attacked fiercelyB.we should greet Future extraterrestrial visitors warmlyC.alien invaders will help humans on earth explore resourcesD.we should take care to treat alien interlopersWhat do you do when you need to look something up? Go to the library? Open an encyclopedia（百科全书）? Click onto the Internet? These days, most people go straight to Wikipedia, the online encyclopedia. But how reliable is it?There is no denying the popularity and usefulness of Wikipedia. It attracts as many as 78 million visitors every month, and the site is available in more than 270 different languages. Its one of the most comprehensive resources available, which includes almost all details, facts and information that maybe concerned. Its got much more information than an ordinary encyclopedia. The site is updated on a daily basis by thousands of people around the world. Anyone with an Internet connection can log on and edit the contents or add a new page. And you dont need any formal training.Of course, there are some controls. Wikipedia has a team of more than 1,500 administrators who check for false information. And main targets for harmful comments（such as politicians） are off-limits to public editing. But with more than 16 million articles to keep an eye on, it isnt easy. So, while Wikipedia benefits from being constantly updated with information from all over the world, its also open to “vandals”（破坏他人财产者）.Some of the damage is easy to notice. One person drew devil horns and a moustache on Microsoft chairman Bill Gates photo, while another edited Greek philosopher Platos biography to say he was a “Hawaiian weather man who is wildly believed to have been a student of Barney the purple Dinosaur and to have been deeply influenced by his dog, Cutie”.But other things are harder to spot. The most common form of vandalism involves adding tiny items of false information into the biography of a famous person. Unbelievably, some of this misinformation has appeared in newspapers, with The Daily Mail, The Guardian and The Independent all having fallen victim to the dirty tricks. For example, in an article about British comedian Sir Norman Wisdom, one newspaper claimed that he co-wrote Dame Vera Lynns wartime hit Therell be bluebirds over the White Cliffs of Dover. He did no such thing. And in another article, it was reported that TV theme tune composer Ronnie Hazlehurst had written the S Club 7 hit Reach. Once again, not true.So, if youre going to use any information from Wikipedia, make sure you double-check it first.5.Which of the following would the author most probably agree with?A.Before using the information from Wikipedia, one should first check it.B.Though popular and widely used, Wikipedia provides little reliable information.C.It is understandable that some people add false information to Wikipedia.D.Updated on a daily basis, any information from Wikipedia is reliable.6.We can learn from the passage that .A.because of its popularity, 78 million people from 270 countries visit Wikipedia monthlyB.Wikipedia is the most comprehensive resource with all information we needC.anyone who has access to the Internet can edit any contents of Wikipedia as they likeD.the primary job of the administrators is to make sure true information is conveyed7.What does the underlined part “off-limits” in paragraph 3 mean?A.Not convenient .B.Not welcome.C.Not accessible. D.Not boundless.8.Whats the writers attitude to Wikipedia?A.Negative. B.Worried.C.Indifferent. D.Objective.语法填空A century ago, there were a hundred thousand tigers in the wild.

The manager just told me to say anything which I could imagine about the city. My first tour was terribly The old bus was not air-conditioned, but it was in the middle of summer, so that was really uncomfortable to be inside the bus. The tourist soon became very hot and bad-tempered. I had a very hard time calm them down. This was because I stayed there only for a few weeks. Then I left and joined in a better company.书面表达假设你是李华，你的英国笔友Bob将于九月到你所在城市的建新华文学校学中文，来信请你在学校附近为他找一套住房。请根据图画提供的信息，写信介绍住房的情况，并告知住房面积为25平方米，月租500元 注意：1.词数100左右。 2.可以适当增加细节，以使行文连贯。答案：.阅读理解A语篇导读：联合国将任命首位“星际外交官”，代表人类与试图和地球联系的外星人进行最初接触。担当这一重任的是马来西亚天体物理学家马斯蓝奥斯玛，她的职责是，假设有外星人接触地球时，协调人类的应对行动。1.C细节理解题。根据第一段中“act as the first point of contact for aliens trying to communicate with Earth.”得知选C项。2.D细节理解题。根据第三段和第六段得知，而非head of the Royal Society。3.A词义猜测题。根据上文得知，联合国各成员国同意保护地球免遭外来物种的污染；下文星际外交官决定支持更加宽容的方法，联系上下文可推断出采用“绝育”的方法，使他们失去生育能力，避免地球遭到外来物种的侵袭。4.D推理判断题。根据倒数第二段斯蒂芬霍金教授已提醒大家，应谨慎对待外星“擅入者”推断出，答案选D项。B语篇导读：文章介绍维基百科的受欢迎程度，指出了其优点，同时也指出了其有些信息有虚假成分的不足之处。5【解析】推理判断题。由文中最后一段可知A选项准确地表达了作者的建议。B选项表述过于否定。C选项表述有误。D选项表述过于肯定。【答案】A6【解析】细节理解题。由第二段第2句可知，A选项表述有误。B选项同样表述与原文不符，原文是“Its one of the most comprehensive resources available”。由第三段的 “And main targets for harmful comments（such as politicians） are off-limits to public editing” 可知，C选项错误。D选项是对第三段第2句的另一种表述，准确反映了原文信息。【答案】D7【解析】词义猜测题。可根据单词的组成结构推测，也可根据上下文推测。第三段第1句“Of course, there are some controls” 应该与题目所在句的意思相呼应，由此可知C选项正确。【答案】C8【解析】观点态度题。从全文来看作者分别介绍了维基百科的优缺点，客观地对其进行了评述。【答案】D.语法填空1.as 2.have jumped 3.are 4.recorded 5.fortune6.but 7.a 8.is believed 9.to double 10.actually.短文改错One day I saw an advertisement in a local newspaper.
