Section Ⅳ　Reading for Writing，Assessing Your Progress & Video Time IS EXPLORING SPACE A WASTE OF TIME AND MONEY? NASA satellite image of Typhoon Goni Countries around the globe are spending billions of dollars and lots of time on various space missions, whether to Mars or other planets much further away. Some people argue that we should stop wasting time and money exploring space. Instead, we should feed the world's poor and find immediate solutions to other problems, such as pollution and fatal diseases. 　However,_others_feel_this_is_a_shallow_view_which_fails_to_realise_how_exploring_space_helps_us　.[1] [1]这句话是主从复合句，feel后的this is a shallow view...是宾语从句，从句中包含which引导的定语从句，该从句修饰a shallow view，realise后是how引导的宾语从句。 Firstly, exploring space has already made a difference in the fight against world hunger. It has directly resulted in the many satellites that now orbit Earth. A number of the satellites record data on land and weather patterns. Then the data is transmitted to scientists on Earth. After careful analysis, the scientists can provide useful recommendations and advice for farmers. As a result, space­based science has helped farming in its efforts to grow enough food to feed Earth's increasing population. Secondly, space exploration has already promoted technological improvements that benefit us all. High­end products around the world are made to a higher standard now because of advanced technology which was first created to meet the requirements for space exploration. For example, space technologies have helped the research and development of different types of new material. They have also helped companies make better heart monitors and other machines that doctors regularly use. Today, space technologies are widely used in all kinds of industries, and everyday products such as GPS, memory foam pillows, and smartphone cameras are changing our lives. Finally, sending astronauts into space has helped people to think about the world's problems and even to find ways to solve them. 　Seeing pictures of our planet as an island in a black sea made people realise that our planet's resources are limited　.[2] In order to provide for such a rapidly increasing population, scientists are trying to find other planets that could one day be our new home. The greatest attention at present is on Mars because it is closer to Earth. In the future, humans may live on both planets. [2]本句是主从复合句。主句使用动名词短语Seeing pictures of our planet...作主语，谓语部分使用“make＋宾语＋宾语补足语(do)”结构，that引导的宾语从句作realise的宾语。 In closing, exploring space provides the world with many different benefits. Therefore, it should continue so as to provide new and better solutions to people's short­term and long­term problems. 探索太空是在浪费时间和金钱吗？ 美国国家航空与航天局台风天鹅卫星图像 全球各国正在花费数十亿美元和大量时间执行各种太空任务，无论是前往火星还是更远的其他行星。有些人认为我们应该停止浪费时间和金钱去探索太空。相反，我们应该养活世界上的穷人，并立即寻找解决其他问题的办法，例如污染和致命疾病。然而，其他人认为这是一个肤浅的观点，没有意识到探索太空是如何帮助我们的。 首先，探索太空已经在与世界饥饿的斗争中发挥了作用。它直接促成了现在环绕地球运行的许多卫星。很多卫星记录了陆地和天气模式的数据。然后数据被传送给地球上的科学家。仔细分析后，科学家们可以为农民提供有用的建议和意见。因此，天基科学帮助农业努力种植足够的粮食来养活地球上不断增长的人口。 第二，空间探索已经促进了有益于我们所有人的技术改进。由于最早是为满足太空探索的需要而创造的先进技术，现在世界各地的高端产品正朝着更高的标准发展。例如，空间技术帮助研究和开发了不同类型的新材料。它们还帮助公司制造更好的心脏监护仪和医生经常使用的其他机器。如今，空间技术被广泛应用于各行各业，如GPS、记忆泡沫枕头、智能手机摄像头等日常用品正在改变我们的生活。 最终，将宇航员送入太空有助于人们思考世界的问题，甚至找到解决这些问题的方法。看到我们的星球的照片像是黑海中的一座岛屿使人们意识到我们星球的资源是有限的。为了供养如此迅速增长的人口，科学家们正在努力寻找其他行星，它们有一天可能成为我们的新家园。目前最受关注的是火星，因为它离地球较近。在未来，人类可能生活在这两个行星上。 最后，探索太空给世界带来了许多不同的好处。因此，它应该继续下去，以便为人们的短期和长期问题提供新的、更好的解决办法。 [重点单词] 1．　shallow　 adj肤浅的；浅的 2．　pattern　 n．模式；图案；模范 3．　resource　 n．资源；财力；物力 4．　closing　 n．停业；关闭；倒闭adj.结尾的；结束的 5．　attach　 vt.系；绑；贴 6．　oxygen　 n．氧；氧气 7．　globe　 n．地球，世界；地球仪→　global　 adj.全球的；世界的 8．　argue　 vt.&vi.论证；争辩；争论→　argument　 n．争论； 争吵；论点 9．　analysis　 n．分析；分析结果→　analyses　 n．(复数)→　analyse　 v．分析 10．　regular　 adj.定期的；经常的；正常的→　regularly　 adv.经常；定期地 11．　limit　 n．极限；限制；界限；范围vt.限制；限量；使限于→　limited　 adj.有限的，受限制的→　limitless　 adj.无限制的；无界限的；无止境的→　limiting　 adj.限制的 12．　mystery　 n．神秘事物；谜→　mysterious　 adj.神秘的；难以理解的，难以解释的，诡秘的 [重点短语] 1．make 　a　 difference有影响，起作用 2．result 　in　导致，造成 3．be transmitted 　to　被发送给 4．provide 　for　 sb.提供生活所需 5．as 　a　 result所以，结果是 6．the efforts 　to_do　 sth.做某事所付出的努力 7．be widely used 　in　 在……方面被广泛应用 8．　in　 closing最后 9．run 　out　 用完；耗尽 10．succeed 　in　 doing sth.成功地做某事 11．　attach　...to...把……贴在……上 [重点句式] 1．Countries around the globe are spending billions of dollars and lots of time on various space missions, whether to Mars or other planets much further away.

The sun is the closest star to the earth.The sun is about 150 million kilometers away. Our sun, like most other stars, gives off power and light by nuclear fusion(核聚变)，which happens exactly where it's the hottest.The sun is about 4.5 billion years old and it will still last six billion years or so. When it runs out of its fuel (燃料)，it would develop into a red star when increasing in size. Since stars are billions of light years away, it may be hard to recognize that stars are in continuous battles with themselves.All the stars have their own gravitational pull (引力) that pulls them. The surprising part is that the nuclear fusion occurring inside the star truly produces an outward (向外的) push to resist (抵抗) the gravitational force, which keeps its present shape. Stars have different colors. The hottest stars are surprisingly the smallest ones and are blue in color. Their temperatures go to about 12,000 Kelvin. Although the yellow­colored stars are the middle­sized ones just like the sun, their temperatures fall to about 6,000 Kelvin. And lastly, the coolest and greatest ones are colored red and the temperatures of them are about 3,000 Kelvin. When looking at the night sky, we may think that stars are up there alone. But don't be surprised that these heavenly bodies in fact come in pairs. And stars can even come in groups of 3 or even 4! [语篇解读]　本文是说明文。作者在文中告诉我们一些有关星星的有趣事实。 1．What will happen when the sun runs out of its fuel? A．It will disappear slowly. B．It will last six billion years. C．It will become a white star. D．It will become larger in size. 解析：D　[细节理解题。根据第二段的“When it runs out of its fuel(燃料)，it would develop into a red star when increasing in size.”可知，当太阳用完了它的能量，它就变成了红色的星球，体积增大了。] 2．What can we learn from Paragraph 3? A．All stars are in a state of balance. B．It's hard for the stars to keep their shapes. C．The stars have the same gravitational pull. D．The stars always stay in peace with one another. 解析：A　[推理判断题。根据第三段的“The surprising part is that the nuclear fusion occurring inside the star truly produces an outward(向外的) push to resist(抵抗) the gravitational force，which keeps its present shape.”可知，星球都处于一种自身的平衡中。] 3．What do we know about the color of the star? A．It is blue when it is very cold. B．It looks red when it is far away. C．It seems yellow when it is over 3,000 Kelvin. D．It has something to do with its size and temperature. 解析：D　[细节理解题。根据第四段内容可知，星星的颜色与它的大小和温度有关。] 4．How do all the stars appear in space in reality? A．They appear only in pairs. B．They appear without rules. C．They stay alone here and there. D．They appear in small groups or in pairs. 解析：D　[细节理解题。根据最后一段内容可知，星星在太空中不是孤立地出现，而是以双子星的形式出现，有时候星星是以三个或四个一组的形式出现。] Ⅱ.概要写作 阅读下面短文，根据其内容写一篇60词左右的内容概要。 The British summer is extremely beautiful. Trees, flowers，birds and butterflies make the whole country look like a big garden.However，many British people have noticed that butterflies have been gradually disappearing from this fantastic scenery during the past several years. What has happened to them? Butterfly Conservation, a charity in the UK, is running a survey to help answer this question. The result is more serious than people expected. According to the survey, among 59 butterfly species found in Britain, more than three quarters of them are suffering a declining (减少的) population, including the most popular ones. What's more, half of all butterfly species are in danger of dying out. Some common species such as the small Tortoiseshell butterfly and the Wall butterfly are dropping sharply.The latter cannot even be seen in many parts of central and southern England. The Blue butterfly, which was commonly seen in the south, has started colonizing(迁徙) to Edinburgh in the past few years. The numbers of butterflies have dropped to a record low in the past several years largely because the summer in the UK is getting cooler. Fortunately, Britain is experiencing a long hot summer this year, compared to the last few summers. Butterfly Conservation believes the warm weather will bring some benefit to the butterflies. Besides, their habitat is getting worse, which is also an important reason for the declining. The survey is still going on. The organizers hope the survey will help raise public awareness (意识) of the value of butterflies in the UK. Butterflies give an indication (显示) of the well­being(健康)of nature.Sir David Attenborough，president of Butterfly Conservation, said：“Large numbers of butterflies tell us that nature is going well. When they decline，it's a warning that other wildlife will be soon going the same way.” ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ 答案：In Britain, butterfly species have been slowly dying out in the last few years.(要点1)A survey conducted by Butterfly Conservation has found three in four butterfly species in Britain are experiencing a decrease with half near extinction.(要点2)This is mainly due to the cold British summer and their worsening habitat.(要点3)The ongoing survey is meant to make people realize the importance of butterflies, which acts as an indicator of the health of nature.(要点4) 学科网（北京）股份有限公司 $
