【文章內(nèi)容簡介】 60。 But are there really aliens in space? British scientist Stephen Hawking, 68, thinks so. He says that people should not look for aliens. He thinks they are dangerous. On a new British TV program, Hawking says, It is quite possible that there are aliens in space. They might live in big spaceships. They have used up all the resources（資源）from their home planet.

They look strange.可知在書里他們很奇怪而且很聰明。故選B。 （2）細節(jié)理解題。根據(jù) On a new British TV program, Hawking says, It is quite possible that there are aliens in space.可知Hawking認為極有可能有外星人，但不確定有。應選C。 （3）細節(jié)理解題。根據(jù) They have used up all the resources（資源）from their home planet. 可知外星人可能用完了他們所有的資源。故選A。 （4）細節(jié)理解題。根據(jù) He thinks such aliens are sure to get resources from Earth and then go away.可知 Mr. Hawking認為外星人會來地球上獲取資源。故選B。 【點評】此題考查閱讀理解。此題涉及細節(jié)理解題，我們先閱讀短文，理解短文大意。然后分析問題，帶著問題仔細閱讀短文，從短文的細節(jié)中找出問題答案。 6．閱讀理解 Is there intelligent（有智力的）life on other planets? For years, scientists said no. or we don39。t know. But today this is changing. Seth Shostak and Alexandra Barnett are astronomers（天文學家）. They believe intelligent life exists（存在）somewhere in the universe. They also think we will soon contact them. Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is time. Scientists believe the universe is about 12 billion years old. This is long enough for other planets to have intelligent life, say Shostak and Barnett. The second reason is size the universe is huge. Tools like the Hubble Telescope（哈勃望遠鏡）have shown that there are at least 100 billion galaxies, says Shostak. And our galaxy, the Milky Way, has at least 100 billion stars. Some planets going around these stars might be similar to the earth. In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes（高倍望遠鏡）allow scientists to discover smaller planetsthe size of Mars or the earthin other solar systems, these planets might have intelligent life. Have beings from space already visited the earth? Probably not, says Shostak. It39。s a long way away. However, intelligent beings may contact us in other way, such as radio signals（信號）. In fact, they may be trying to municate with us now, but we don39。t have the right tools to receive their messages. However, this is changing. By 2025, we could make contact with other life forms in our universe and we might help each other. （1）What is the main idea of Paragraph 2? A.The age and size of the earth.B.Something about the Milky Way.C.The reasons why intelligent life might exist.D.The earth is the only planet with intelligent life.（2）Why was it hard to look for signs of intelligent life in the universe in the past? A.There were not any smaller planets.B.There were not any powerful telescopes.C.The astronomers were not interested in them.D.The Milky Way didn39。t exist at that time.（3）Why haven39。t beings from space visited us yet according to Shostak? A.Because they39。re afraid of us.B.Because it39。s long way away.C.Because they don39。t want to see us.D.Because they don39。t know how to use radio signals.（4）What does the underlined phrase life forms in the last paragraph mean? A.Messages.B.Tools.C.Radio signals.D.Intelligent beings.【答案】 （1）C（2）B（3）B（4）D 【解析】【分析】短文大意： 本文敘述了科學家認為其他星球也存在智能生命，因為宇宙形成的時間這么長，足夠其他星球形成生命；其次宇宙這么大，周圍會有跟地球相似的星球。不久來自太空的生命有可能將會和我們聯(lián)系，我們可能到2025年，也會和他們?nèi)〉寐?lián)系，我們可能會互相幫助。 （1）段落大意題。根據(jù)段落主題句Why do Shostak and Barnett think intelligent life exists on other planets?可知這個段落講的是有智慧的東西在其它星球存在的原因。故選C。（2）推理判斷題。根據(jù) In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes（高倍望遠鏡）allow scientists to discover smaller planetsthe size of Mars or the earthin other solar systems, these planets might have intelligent life. 過去，在宇宙中很難找到智慧生活的標志，但是現(xiàn)在，高倍望遠鏡讓科學家發(fā)現(xiàn)了更小的行星火星的大小或地球在其它太陽系，這些行星可能有智慧的生命。可知過去人們很難發(fā)現(xiàn)智慧生命的標志是因為沒有高倍望遠鏡。故選B。（3）推理判斷題。根據(jù) Have beings from space already visited the earth? Probably not, says Shostak. It39。s a long way away. ，因為路途遙遠。故選B。（4） 詞義猜測題。根據(jù) However, intelligent beings may contact us in other way, 可知智能生命可能會用其他方式聯(lián)系我們，故推測此處的life forms指的是intelligent beings，故選D?！军c評】此題考查閱讀理解。這道題涉及段落大意，推理判斷和詞意猜測。段落大意可根據(jù)段落的主題句決定。對于推理判斷題，我們要根據(jù)文章的細節(jié)內(nèi)容進行推理，確定正確答案。對于詞意猜測題，我們要根據(jù)上下文的聯(lián)系確定，找出正確答案。7．閱讀理解 What would you say when we told you that you could learn to speak a new language in only 7 days? Pretty unbelievable, right? But how could it be? To find out, we spoke to David－one of our brave Babbel learners－to see how the Babbel app successfully got him speaking French in just one week. How much time did you learn each day? I didn39。t need to give my whole life over to learning French. Each Babbel lesson takes only 15 minutes, and I give myself the certain aim（目標） of finishing three Babbel lessons daily. This took 45 minutes each day. How did the Babbel app help you learn so quickly? The Babbel app has a course plan for beginners that taught me how to make sentences in French within the first few days. Then I was able to personalize（個性化）my learning by choosing lessons on eating, drinking, music, culture, travelling and so on. This made me quickly enlarge（擴大） my vocabulary! This way of learning kept me really interested, and made sure I wasn
