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。 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。 1．What do the public think of Blue Origin's space tourism flights? A．Successful. B．Inspiring. C．Beneficial. D．Costly. √ 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。 2．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. √ 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。由此可知，Space View的目的是使太空旅游大众化。 3．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. √ 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。 4．What would be the best title of the passage? 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? √ B (2024·湖州高一检测) The development of China's space program was first suggested in 1956 by the father of Chinese rocket science，Qian Xuesen (1911－2009).As a result of a lot of preparation and planning，the Shenzhou crewed program began in 1992，and the first Chinese astronaut，Yang Liwei，went into space in 2003.Chang'e-1，a lunar orbiter was launched in 2007，while Tiangong-1，an experimental crewed space station，was launched in 2011. In 2019，Chang'e-4 made a soft landing on the far side of the moon.It was mankind's first successful soft landing on the far side of the moon.A “soft” landing is one where the spacecraft lands in a controlled way，and gets no damage.Twelve hours later，the small Yutu-2 rover was released.To understand why Chang'e-4's soft landing was such an achievement，consider the difficulty of any space mission，especially one to the far side of the moon.While the far side of the moon is often called the dark side of the moon，it is not really dark. The main problem with landing on the far side of the moon is communication.There is no clear line of sight between the far side of the moon and the earth.This normally makes radio communication with spacecraft on the far side of the moon impossible.Chinese engineers came up with a unique solution.Before Chang'e-4's mission，they sent the Queqiao communications satellite into space.When engineers needed to communicate with Chang'e-4 and Yutu-2，they could send radio messages to Queqiao.The messages would then be sent from the satellite down to the lander and rover.This allowed for contact between earth and the far side of the moon. One of the experiments of Chang'e-4's mission was designed to test a closed ecological(生态的) system that could be extremely important for long-term space missions：The plants produce food and oxygen for the fruit flies，while the fruit flies produce carbon dioxide for the plants.This experiment worked for nine days，but it had to be stopped when the temperatures dropped below －52℃. 语篇解读　本文是一篇说明文。中国的“嫦娥四号”实现了人类首次成功在月球背面软着陆，文章主要介绍了其意义及中国工程师是如何解决通信问题的。 细节理解题。根据第一段中“As a result of a lot of preparation and planning...an experimental crewed space station was launched in 2011.”可知，基于充分的准备和规划，中国的太空计划一直在进步。故选D。 5．What can we know according to the passage? A．The first Chinese astronaut，Yang Liwei，went into space in 2007. B．Qian Xuesen is considered the father of the Chinese space program. C．The development of space program in China started in ancient times. D．The Chinese space program has been advancing with preparation and planning. √ 细节理解题。根据第二段前两句及倒数第二句可知，嫦娥四号在月球的着陆是一个很大的成就，这是因为前往月球背面的任务难度极大，而嫦娥四号在月球背面实现了软着陆。故选B。 6．Why was Chang'e-4's landing on the moon such an achievement? A．Because Chang'e-4 landed on the moon successfully. B ．Because Chang'e-4 made a soft landing on the dark side of the moon. C．Because man had never landed on the moon with the difficulty of space mission. D．Because it was the first time that humans had landed on the moon without any damage. √ 细节理解题。根据最后一段末句可知，嫦娥四号停止生态实验是因为温度太低，无法继续。故选C。 7．Why was the ecological experiment of Chang'e-4 stopped? A．It got too dark to continue. B．The lander no longer had power. C．It got too cold for the experiment to work. D．There was not enough oxygen on the moon. √ 文章出处题。根据全文内容尤其是第二段前两句可知，文章主要介绍了嫦娥四号在月球背面实现软着陆的意义及中国工程师是如何解决地月通信问题的。由此可知，本文可能出自一本杂志。故选D。 8．Where is this passage probably from? A．A story book. B．A textbook. C．A science fiction. D．A magazine. √ Ⅱ.阅读七选五(每小题2.5分，共12.5分) (2024·厦门高一检测) Interesting Space Facts As time goes by，technological advancements have made us learn more facts about space in the past century than in all time before that.We've already searched the universe for the most amazing space facts，including facts about the planets in our solar system，moons，the Milky Way and beyond! 1 The highest mountain discovered is the Olympus Mons，which is located on Mars.It is 16 miles high，making it nearly 3 times higher than Mount Everest. 2 That's the size of Arizona! The sun weighs about 330，000 times more than Earth. 3 In fact，the sun is so huge that it contains 99.85% of all mass in our solar system. Footprints left on the moon won't disappear as there is no wind.But wait a minute. 4 Well，it actually wasn't blowing.That blowing you see is because of a telescopic horizontal rod (望远镜水平杆) that the astronauts were struggling to remove from the flag's top. 5 This is due to the lack of gravity in space causing the vertebrae (椎骨) to expand a little.However，this extra height is lost when they re-enter the Earth's atmosphere and are affected by the Earth's gravity again. A．We're pretty sure they will make you interested! B．New discoveries will no longer be made in the future. C．It is so large that it can contain about 1，300，000 Earths! D．Not only is it tall，but it's 114，000 square meters as well. E．All these space facts may not be true at the time of writing. F．Astronauts can grow about two inches in height when in space. G．If there's no wind to blow them away，then why is the flag blowing? 语篇解读　本文是一篇说明文。文章介绍了一些太空中有趣的事。 根据上文可知，文章要介绍一些关于太空的事情，一定会让读者感兴趣。A项(我们很肯定它们会让你感兴趣！)符合语境。 As time goes by，technological advancements have made us learn more facts about space in the past century than in all time before that.We've already searched the universe for the most amazing space facts，including facts about the planets in our solar system，moons，the Milky Way and beyond! ___________________________________________ A．We're pretty sure they will make you interested! 根据上文可知，本段在对奥林匹斯山的具体情况进行介绍，D项中的it指代上文的“the Olympus Mons”。D项(它不仅高，而且有11.4万平方米。)符合语境。 The highest mountain discovered is the Olympus Mons，which is located on Mars.It is 16 miles high，making it nearly 3 times higher than Mount Everest. _____________________________________________________ That‘s the size of Arizona! D．Not only is it tall，but it's 114，000 square meters as well. 根据上文可知，太阳的重量大约是地球的33万倍，空处承接上文，继续描述太阳的大小，C项中的It指代上文中的“The sun”。C项(它是如此之大，以至于它可以容纳大约130万个地球！)符合语境。 The sun weighs about 330，000 times more than Earth. ___________________________________________________ In fact，the sun is so huge that it contains 99.85% of all mass in our solar system. C．It is so large that it can contain about 1，300，000 Earths! 根据上文可知，本段主要讨论月球上是否有风，G项中的wind和上文对应。G项(如果没有风把它们吹走，那为什么旗帜在飘扬？)符合语境。 Footprints left on the moon won't disappear as there is no wind.But wait a minute. _________________________________________________________ ________ Well，it actually wasn't blowing.That blowing you see is because of a telescopic horizontal rod (望远镜水平杆) that the astronauts were struggling to remove from the flag's top. G．If there's no wind to blow them away，then why is the flag blowing? 根据下文可知，这是由于太空中缺乏重力导致椎骨略微扩张，空处和下文形成因果关系，说明宇航员在太空中可以长高。F项 (宇航员在太空中可以长高2英寸。)符合语境。 ______________________________________________________ This is due to the lack of gravity in space causing the vertebrae (椎骨) to expand a little.However，this extra height is lost when they re-enter the Earth's atmosphere and are affected by the Earth's gravity again. F．Astronauts can grow about two inches in height when in space. 返回 谢 谢 观 看 ！ 返回 $$
