If you ask me, I'll definitely give a positive answer. The exploration of space has a direct impact on the lives of humans, as well as the state of our world.Satellites moving around the earth enable communication across the world, connecting people of different continents and broadcasting information worldwide.The navigation system can identify our location anywhere.Furthermore, weather satellites can predict harmful weather conditions, which allows humans to prepare for deadly natural disasters and save lives. Space programs can also indirectly contribute to the solution to poverty and world hunger.For example, large pieces of land could be used far better if humans applied technologies.The most effective tool is the artificial earth satellite.It can screen areas of land within a very short time, indicating useful measures such as the condition of crops, soil, rainfall, and droughts.It can then send this information to ground stations on the earth for better use. Furthermore, access to better education means better life prospects and opportunities for human beings.Rural (乡村的) communities have disadvantaged access to education and satellite communication technologies are trying to bridge this gap.With the development of technology, students can now access any information and connect with peers and teachers in different parts of the world through video conferences and the creation of virtual classrooms. Space exploration is something we can do for future generations.Mankind is using the resources provided on the planet, but these will run out one day.Overpopulation can be a threat for all mankind.With the development of space technology, it will be wise to use and explore the vast potential of other planets, such as the availability of mining resources on asteroids (小行星) or other planets. For the exploration of the universe, perhaps the most advantageous of all is that it will unite us to work together for a common purpose, regardless of our differences. 语篇解读：本文是一篇说明文。文章具体介绍了进行探索太空的好处和必要性。 1．What can space exploration do according to paragraph 2?

A．Why Space Exploration Is Important? B．Why Humankind Should Keep Exploring? C．Why We Should Improve Space Technology? D．Why Humans Should Keep Developing Technologies? √ 解析：标题归纳题。通读全文，并结合第一段“Should humans explore space? If you ask me, I'll definitely give a positive answer.”可知，文章认为人类应该进行太空探索，并具体介绍了探索太空的好处和必要性。因此，A项“为什么太空探索很重要？”符合文章主旨，最适合作为标题。 B The success of Blue Origin's space tourism flights has caused concerns among the public.Many say it is a rich person's game that is unnecessary when Earth badly needs help. For Jane Smith, co－founder of Space View, the industry is not preventing Earth from help, but helping its residents better understand their world. “Space exploration has played an important role in forming our understanding of our planet，” Smith said in an interview.“The most downloaded image in history is Earthrise that was taken in 1968 by Apollo astronauts as they circled the moon.Taking the photo was not on their schedule of activities but they were so struck by the scene that they rushed to record it.That one photograph helped humanity see Earth as a planet in space, and inspired an environmental movement.” Space View, founded in 2019, is a firm using a giant balloon to send humans into the stratosphere (平流层)．It is designing a luxurious capsule (豪华太空舱) that fits six passengers, who can relax in seats or enjoy a snack while flying 20 miles above Earth. Smith explained that eventually, millions of people will have exciting space experience.Tickets for a ride through Space View currently run $125,000 a seat, but Smith said the “long－term vision is to bring the price down significantly”．“A ticket price of, say, $30,000－$40,000 would make the space trip affordable to many millions of people，” she added. When asked about the public comments, Smith answered, “When people visit space and experience our Earth from that fantastic point, they connect deeply with our planet and the singular human family that inhabits it.It broadens their perspective (视角) and they return with a deepened understanding of social and environmental causes.” 语篇解读：本文是一篇新闻报道。文章报道了“蓝色起源”太空旅游项目的成功，许多人认为这是富人的游戏，但其目标是使太空旅游大众化。 5．What do the public think of Blue Origin's space tourism flights? A．Successful.　　　　　　 B．Inspiring. C．Beneficial. D．Costly. 解析：细节理解题。根据第一段中的 “Many say it is a rich person's game that is unnecessary when Earth badly needs help.”可知，公众认为蓝色起源的太空旅游是昂贵的。 √ 6．Why does Jane Smith mention the photo of Earthrise? A．To review the history of the photo. B．To express respects to Apollo astronauts. C．To remind people of the beauty of the space. D．To explain the significance of space exploration. √ 解析：推理判断题。根据第三段中的“That one photograph helped humanity see Earth as a planet in space, and inspired an environmental movement.”可推知，Jane Smith提到地球升起的照片是要解释太空探索的意义。 7．What do we know about Space View? A．It has made much money from space tourism. B．It aims to make space tourism popular. C．It plays a part in Blue Origin's flights. D．It has sent six passengers into space. 解析：推理判断题。根据倒数第二段可知，Space View的长期目标是大幅降低票价，3万至4万美元的票价将使数百万人负担得起太空旅行。因此，Space View的目的是使太空旅游大众化。 √ 8．What would be the best title of the text? A．Is Space Tourism a Rich Person's Game? B．Can Everyone Experience Space Tourism? C．Why Should the Public Know about Space? D．How Has Space Tourism Developed Rapidly? √ 解析：标题归纳题。通读全文可知，本文主要介绍了蓝色起源太空旅游项目的成功，许多人认为这是富人的游戏，但其目标是使太空旅游大众化。由此可知，选项A“太空旅游是富人的游戏吗？”是本文的最佳标题。 (二)完形填空( ) It took humans thousands of years to understand our own planet, and centuries __9__ our neighboring planets.Nowadays, new worlds are being __10__ every week. Up to the present time, astronomers have __11__ more than 370 “exoplanets” — planets orbiting (绕……运动) outer space stars (恒星) other than our sun.There is a “hot Saturn (土星)” 260 light－years from Earth that orbits its parent star so __12__ that a year there lasts less than three days.__13__ another star 150 light－years out is a burning “hot Jupiter (木星)，” where upper atmosphere (大气层) is being burned to form a huge comet－like tail.Astronomers have found another three __14__ orbiting a pulsar (脉冲星) — the remains of a once huge star shrinking (收缩) into a small atomic nucleus the __15__ of a city.Some planets have obviously fallen into their suns.Others have been thrown out of their __16__ to become “floaters” that float in the darkness of the universe. Among all these, scientists are eager to find a clue of the __17__： planets like the Earth.That is, planets orbiting their stars at just the right distance — neither too hot nor too cold — to __18__ life as we know it.We have not yet found planets that are quite like our own, __19__ because they're inconspicuous (不起眼的)．To see a planet as __20__ and slim as ours among the brightness of its star is like trying to see a firefly in a fireworks display.__21__ by pushing technology to the __22__， astronomers are rapidly approaching the day when they can find another Earth.And when they do, they can examine it for __23__ of life. 语篇解读：本文是一篇说明文。文章主要介绍了除地球外的其他“系外行星”，并介绍了人类为了寻找与地球相似的行星所做出的努力。 9．A.explore B．separate C．forget D．defend 解析：人类花了数千年的时间才了解了我们自己的星球，并花了数百年的时间探索我们邻近的星球。explore“探索”。 √ 10．A.revised B．discovered C．saved D．created 解析：根据句中“new worlds”可知，随着人类的不断探索，应该是有新的世界被发现。 √ 11．A.travelled B．damaged C．recognized D．ignored 解析：根据下文“hot Saturn”和“hot Jupiter”可知，下文介绍的是其他“系外行星”。由此可知，句中指天文学家已经识别(recognized)了370多颗“系外行星”。 √ 12．A.slowly B．easily C．wrongly D．rapidly 解析：根据句中“a year there lasts less than three days”可知，在那里一年的持续时间不到三天。由此可知，“热土星”绕其母星运行的速度很快(rapidly)。 √ 13．A.Removing B．Circling C．Lighting D．Showing 解析：环绕 (Circling)150光年外的另一颗恒星移动的是一颗燃烧的“热木星”，在那里上层大气正在燃烧，形成一个巨大的彗星状尾巴。 √ 14．A.stars B．moons C．planets D．satellites 解析：根据上文“exoplanets”可知，本段内容介绍的是“系外行星”。由此可知，句中指另外三颗围绕脉冲星运行的行星。 √ 15．A.type B．distance C．power D．size 解析：根据句中“a once huge star”中的“huge”可知，这里介绍的是恒星的大小。由此可知，句中指“缩小成一个城市大小的小原子核”。 √ 16．A.authorities B．species C．systems D．facilities 解析：根据句中“become ‘floaters’ that float in the darkness of the universe”可知，其他行星成为漂浮在宇宙黑暗中的“漂浮者”。由此可知，它们是被赶出了它们所在的系统。 √ 17．A.familiar B．previous C．unknown D．distant 解析：在所有这些中，科学家们渴望找到一条熟悉的(familiar)线索：像地球这样的行星。 √ 18．A.hide B．discover C．injure D．support 解析：根据句中“neither too hot nor too cold”可知，“既不太热也不太冷”的条件下应该是可以支持(support)人类生存的。 √ 19．A.luckily B．instantly C．probably D．officially 解析：我们还没有发现与我们自己的行星非常相似的行星，可能(probably)是因为它们不起眼。 √ 20．A.small B．bright C．blue D．clear 解析：根据句中“a firefly in a fireworks display”中的“firefly”可知，在烟花表演中的萤火虫是小的，不容易看到。由此可知，句中指渺小的行星，在明亮的星光中是不起眼的。 √ 21．A.And B．Yet C．So D．Thus 解析：然而，通过将技术推向极限，天文学家正在迅速接近找到另一个地球的那一天。上下文为转折关系。 √ 22．A.limits B．ends C．opposites D．beginnings 解析：根据句意和生活常识可知，应该是随着技术的发展，天文学家有可能找到另一个地球。由此可知，句中指将技术推向极限(limits)。 √ 23．A.examples B．designs C．means D．signs 解析：根据上文内容可知，天文学家正在寻找与地球相似的星球。由此可知，他们要检查那些星球是否有生命迹象(signs)。 √ (三)主题微写作(15分) 利用本课主题词汇补全下面短文。 Human beings have always been interested in ①__________(外太空)．China has been pushing back the boundaries of ②_______________ (太空探索) on its own over the past decades, whose space activities, including ③_________________(发射卫星), the first ④____________(太空行走) of the Chinese ⑤___________ (宇航员), etc., are intended to ⑥ ______________________________(弄清宇宙的奥秘) and work for the existence and the development of mankind. outer space space exploration launching satellites walk in space astronauts find out the secrets of the universe It is particularly worth mentioning that China has already successfully launched the core module of its ⑦____________(太空站) into space, which is mainly used for scientific and technological experiments, like ⑧____________________________________________(收集数据并将其传回地球)．Chinese astronomers hope that space exploration will not only ⑨_______________________________(为人类的问题提供解决办法) but also ⑩______________________________(帮助我们延续生存，直到未来)． space station collecting data and sending them back to the Earth offer solutions to people's problems help us survive well into the future 本课结束 更多精彩内容请登录：www.zghkt.cn $
