During their time in space，they made many breakthroughs for China's space program. In terms of④ the mission，it was the longest so far，and Wang was the first Chinese female astronaut to conduct a spacewalk.The astronauts also carried out the docking⑤ of a cargo spacecraft⑥ by remotely controlling the Tianhe space station module's mechanical arm. They also successfully undocked the cargo spacecraft and docked with it again，fully demonstrating⑦ the arm's functional ability. From all aspects，it is fair to say that the Shenzhou XⅢ mission has been a success. Even the astronauts' return to the Earth witnessed⑧ some major breakthroughs for China's space endeavors⑨. 单元话题导入 语篇导读： 从各个方面来看，可以说神舟十三号任务是成功的。就连宇航员重返地球也见证了中国太空事业的一些重大突破。中国的太空计划达到了新的高度。 阅读助手： ①the reentry module 返回舱 ②at the designated landing site在指定的着陆点 ③mission n．(军用飞机或航天火箭的)飞行任务 ④in terms of 就……而言 ⑤dock v．(航天器)在太空对接 undock v．分离 ⑥a cargo spacecraft 货运飞船 ⑦demonstrate v．证明，展示 ⑧witness v．见证 ⑨endeavor n．努力 Section Ⅰ　Welcome to the unit & Reading 内容索引 整体预习 1 语篇理解 2 课时精练 5 夯实双基 3 互动探究 4 整体预习 返回 ①astronaut n．宇航员，航天员 ②come to an end结束 ③differ from与……不同 ④gravity n．重力，地球引力；严重性；严肃 原文呈现 名师圈点 Life on a space station Living in space is every would-be astronaut's① dream.

Max Goes to the Space Station Age range：All ages Jeffrey Bennett's tale about a dog called Max and his adventures to the International Space Station isn't only an accurate look at what life in space is like.The book was actually sent into space and joined the station's library in 2014 as part of the Story Time from Space project.It enables readers to learn all sorts of fun facts about space. 语篇解读　本文是一篇应用文。文章主要介绍了四本适合孩子在假期阅读的有关太空的书籍。 1．What's the text mainly intended to introduce? A．How to find holiday gifts for your kids. B．Some kids' space books for the holidays. C．How to inspire kids' interest in the universe. D．Some books about the theories of the universe. 推理判断题。根据文章第一段可推知，本文主要是介绍四本适合孩子在假期阅读的有关太空的书籍，故B项正确。 √ 2．Which book can inspire a sense of determination in readers? A．Max Goes to the Space Station. B．Margaret and the Moon. C．I Am Neil Armstrong. D．Look Inside Space. 细节理解题。根据文中I Am Neil Armstrong部分的“Meltzer begins the story with young...continued this spirit throughout his career(职业).”可知，I Am Neil Armstrong这本书展示了主人翁的坚定意志，故C项正确。 √ 3．In which aspect is Max Goes to the Space Station different from the other three books? A．It has experienced space travel. B．It is suitable for kids of all ages. C．It is a biography of an astronaut. D．It has won a prize as a bestseller. 细节理解题。根据文中Max Goes to the Space Station部分的“The book was actually sent into... of the Story Time from Space project.”可知，这本书的与众不同之处在于，它经历过太空飞行，故A项正确。 √ B Photographic self-portraits have existed for as long as cameras have been in human hands.But what about selfies in space? On Twitter last year，NASA astronaut Edwin Aldrin，who famously became the second man to walk on the moon in July 1969，laid claim to a spaceflight first：taking the first selfie in space during the Gemini Ⅻ mission in 1966. “For me，it needs to be digital to be selfie，” argues Jennifer Levasseur，a director at the Smithsonian National Air and Space Museum. According to Levasseur，the concept of a selfie is directly linked to Internet culture. “The thing that makes a selfie is sharing it，” she says. Still，astronauts have been carrying cameras aboard space vehicles since the 1960s.In 1966，Aldrin used a Hasselblad camera designed specifically for space.Hasselblad also painted the first camera in space a matte(磨砂) black to reduce reflections in the orbiter window.But cameras used in space need to survive extreme conditions，like temperature swings from －149 to 248，so Hasselblad painted later model silver. Astronauts visiting the moon then had to take out the film and leave their camera bodies behind when they returned to Earth，because early space missions were limited by a weight limit on the returned trip.Then a big change in space camera technology came after the space shuttle Columbia broke apart on its return to Earth in 2003，Levasseur notes.“Fear that they'd never be able to bring film back from space and lose all that hard work accelerated the push for digital，” she says. Today，astronauts also have access to the Internet and social platforms in space and can post true space selfies made using digital cameras.Similarly，space robots are participating in selfie culture，capturing remote pictures of themselves in space or on other planets and sending them back to Earth. 语篇解读　本文是一篇说明文。文章主要介绍了太空自拍的历史。 4．Why do selfies in space need to be digital according to Jennifer Levasseur? A．Astronauts are fond of studying technology. B．Astronauts are eager to be famous on the Internet. C．Astronauts desire to communicate on social platforms. D．Astronauts want to overcome the fear in space. 推理判断题。根据第二段“For me，it needs...‘The thing that makes a selfie is sharing it，’ she says.”可推断出，Jennifer Levasseur认为太空自拍之所以需要数字化是因为宇航员想与人类的社交平台交流与互动。故选C。 √ 5．Why can the Hasselblad camera adjust to the temperature changes in space? A．It is painted silver. B．Its matte black gathers light. C．Its design is special. D．It can reduce reflection itself. 细节理解题。根据第三段中的“But cameras used in space need to survive extreme conditions...Hasselblad painted later model silver.”可推断出，Hasselblad摄像机能适应太空气温的变化是因为它被漆成了银色。故选A。 √ 6．What contributed to the faster development of camera technology in space? A．The heavy space tasks. B．A returned space shuttle. C．A spaceflight crash. D．The improved film. 细节理解题。根据第四段最后两句可知，是一次太空飞行事故促成了太空摄像技术的快速发展。故选C。 √ 7．What can be a suitable title for the text? A．The Origin of Selfies in Space B．The Brief History of Selfies in Space C．The Significance of Selfies in Space D．The Popularity of Selfies in Space 标题归纳题。本文第一段最后一句引出太空自拍的话题后，下文介绍了自拍的起源，以及如今太空自拍的现状。由此可推断出，本文简单介绍了太空自拍的历史。所以最适合这篇文章的题目是“太空自拍的简史”。故选B。 √ Ⅱ.阅读七选五 　　When thinking about placing a human being in space，one of the most important questions is how to design special clothing needed to protect the person from the dangers of the space environment.1______ The fierce heat of the sun can cause severe burns.The lack of the atmosphere can cause gases in the body to expand and even burst.With no oxygen to breathe，a human being will die in only a few moments.2______ So is damage from small pieces of rocks and objects like meteoroids (流星体). 　　In 1933，an American flyer，Wiley Post，designed one of the first successful devices to protect a pilot at extreme heights.3______ Astronauts in the American space agency flew the first American space flights in the early 1960s.The clothing was similar to that invented by Wiley Post. 　　4______ It lets them move，do useful tasks，and stay outside their spacecraft in comfort and safety for several hours.The spacesuit is called the shuttle extravehicular mobility unit or EMU.It was designed to endure longer and to permit more movement than earlier spacesuits. 　　The EMU has a number of parts that an astronaut can link together by using only one hand，which makes it possible for each astronaut to select the parts that fit correctly. 　　Nowadays，NASA scientists are also considering the kind of spacesuit that would be needed for exploration on the planet Mars.5______ The equipment may also have to protect astronauts from particles carried in the wind on Mars.And，they must be easy to repair and keep clean during a longer flight to and from the red planet. A．Radiation from the sun is another risk in space. B．The cold of space will freeze skin in a short time. C．Today，astronauts wear very different protective clothing. D．Special spacesuits have been used for exploration of Mars. E．EMU has many parts that can be linked together by using two hands. F．It was a large device that looked like a can surrounded the pilot's head. G．Because of the gravity on Mars，spacesuits may have to be designed to be lighter than suits used in orbit or on the moon. 语篇解读　本文是一篇说明文。文章主要介绍了当考虑把一个人放到太空时，最重要的问题之一是如何设计特殊的服装来保护这个人免受太空环境的危害。 　　When thinking about placing a human being in space，one of the most important questions is how to design special clothing needed to protect the person from the dangers of the space environment.1______________________________________________ The fierce heat of the sun can cause severe burns.The lack of the atmosphere can cause gases in the body to expand and even burst.With no oxygen to breathe，a human being will die in only a few moments. 2_____________________________________________ So is damage from small pieces of rocks and objects like meteoroids (流星体). B．The cold of space will freeze skin in a short time. A．Radiation from the sun is another risk in space. 第一段主要讲述了太空环境的危险因素，如空后讲的酷热、缺氧等。根据段意，B项符合语境，寒冷会在短时间内冻住皮肤，这是太空环境的一项危险因素。 该空仍旧是列举太空环境的危险因素，根据空后“So is damage from small pieces of rocks and objects like meteoroids(流星体).”可知A项符合语境。 　　In 1933，an American flyer，Wiley Post，designed one of the first successful devices to protect a pilot at extreme heights. 3__________________ _________________________________________________ Astronauts in the American space agency flew the first American space flights in the early 1960s.The clothing was similar to that invented by Wiley Post. F．It was a large device that looked like a can surrounded the pilot's head. 根据上一句的信息词devices，并结合F项中的代词It和device等信息，可以判断F项符合语境。 　　4______________________________________________________ It lets them move，do useful tasks，and stay outside their spacecraft in comfort and safety for several hours.The spacesuit is called the shuttle extravehicular mobility unit or EMU.It was designed to endure longer and to permit more movement than earlier spacesuits. C．Today，astronauts wear very different protective clothing. 该空是该段的主题句。根据空后可知，该段介绍的是有关太空防护服的事情。因此C项符合语境。 　　The EMU has a number of parts that an astronaut can link together by using only one hand，which makes it possible for each astronaut to select the parts that fit correctly. 　　Nowadays，NASA scientists are also considering the kind of spacesuit that would be needed for exploration on the planet Mars. 5__________________________________ _______________________________________________________________________________ The equipment may also have to protect astronauts from particles carried in the wind on Mars.And，they must be easy to repair and keep clean during a longer flight to and from the red planet. G．Because of the gravity on Mars，spacesuits may have to be designed to be lighter than suits used in orbit or on the moon. 根据该空前一句的信息词“the kind of spacesuit”以及后一句的意思可知，此空也应该表示一项防护措施，因此G项符合语境。 Ⅲ.完形填空 Wanda Smith always wanted to be a school teacher but sometimes meeting life's demanding realities can mean a dream delayed.A mother of three，Smith also needed to 1 her mom.Obviously，shouldering her family 2 ，she took a job as bus monitor for a school in Texas.
