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.,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 ………………◎ 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 ⑤absence n．缺乏，不存在；缺席 absent adj.缺席的；缺少的；心不在焉的 ⑥float vi.飘动，漂流；浮vt.使浮动，使漂流 ⑦cupboard n．壁橱；橱柜，衣柜 ⑧ceiling n．天花板；上限 ⑨bother vt.使烦恼，使担心；花费时间精力(做某事)；打扰 vi.花费时间精力(做某事) n．麻烦，困难 ⑩occupy vt.占用，使用；居住；占领，侵占；使忙于 ⑪mission n．任务；使命，天职；军事行动；太空飞行任务 ⑫evaluate vt.评估，估计，评价 evaluation n．评价；评估；估价 ⑬creature n．动物，生物；人 ⑭mosquito n．(pl.mosquitoes or mosquitos)蚊子 ⑮microscope n．显微镜 ⑯carry out experiments 进行实验 ⑰work on 对……起作用；继续工作；从事于…… ⑱cast new light on 使进一步了解…… ⑲lead to 导致；通向 ⑳maintenance n．维护，保养；维持，保持 take place 发生；举行 circumstance n．条件，状况；(circumstances)境况，(尤指)经济状况 exposure n．面临，遭受；揭露；报道 radiation n．辐射，放射线 at a time 一次；每次 visible adj.看得见的；明显的 electric shock 触电；电击 in view of 鉴于，考虑到 luxury n．不常有的乐趣(或享受)；奢侈品 tube n．管，管子；软管 furthermore adv.此外，再者 pill n．药丸，药片 of vital importance 极其重要的 vital adj.必不可少的，对……极重要的；维持生命所必需的 discipline vt.严格要求(自己)；惩罚；训练 n．训练，纪律；行为准则；自制力 at least 至少 leisure n．闲暇，空闲 crew n．全体工作人员；全体乘务人员，全体船员；专业团队 at a speed of 以……的速度 worth it 值得；值得一干 ◎……………… Life on a space station Living in space is every would­be astronaut’s① dream.My six­month stay on a space station has come to an end②，and it has been a challenging but magical adventure.I bet you’d love to know what daily life is like up in space and how it differs from③ that on the Earth—the low gravity④ definitely makes ordinary things strange！【1】 【1】本句为主从复合句。what和how引导两个并列的宾语从句。 The strangeness of living in space is apparent from the moment we sleep.Due to the near absence⑤ of gravity in space，we have to attach ourselves so that we don’t float⑥ around.We usually sleep in private quarters，which are more like large cupboards⑦，or in sleeping bags attached to the walls or the ceiling⑧．【2】It’s strange that we try to sleep with no pressure against our back，but the unusual beds don’t bother⑨ us any more．【3】After about eight hours of sleep，we start our day of work. 【2】本句中which引导非限制性定语从句，修饰先行词quarters，过去分词短语attached to the walls or the ceiling作sleeping bags的后置定语。 【3】本句为but连接的并列句。第一个分句中It作形式主语，that引导的从句作真正的主语。 The routine tasks that occupy⑩ most of the day are demanding，but they can also be extremely rewarding．【4】 Our main mission⑪ is to conduct scientific research.We need to evaluate⑫ the effects of low gravity on animals and plants.Creatures⑬ such as mice，fish and mosquitoes⑭ have also been sent to the station! In a low­gravity environment，we can learn more about changes in cells and microorganisms under the microscope⑮.As well as doing these biological experiments，we carry out experiments⑯ in other research fields.I have been working on⑰one experiment which locates and tracks lightning over large regions of the Earth．【5】Hopefully，it will cast new light on⑱ the Earth’s climate and lead to⑲ better lightning protection.With so much going on，the space station needs a lot of maintenance⑳，so we constantly check support systems and do some cleaning．【6】 【4】本句为but连接的并列句。第一个分句中that occupy most of the day为定语从句，修饰先行词The routine tasks。 【5】本句中which引导定语从句，修饰先行词one experiment。 【6】本句为so连接的并列句。第一个分句中With so much going on为with的复合结构作状语。 The most challenging work takes place when we need to perform tasks outside the space station，such as testing new equipment，monitoring scientific experiments or repairing the space station.In the circumstances，it’s time for a spacewalk.First，we put on our spacesuits，which allow us to breathe in space and protect us from exposure to the cold and radiation.【7】Then we head out，and sometimes perform tasks for hours at a time，with the beautiful Earth visible below.Splendid as the view of the Earth is，spacewalking is not as exciting as you might think．【8】It’s probably the most dangerous work，with potential risks such as electric shocks.That’s why every spacewalk is carefully planned. 【7】本句中which引导非限制性定语从句，修饰先行词spacesuits。 【8】本句中Splendid as the view of the Earth is为as引导的让步状语从句，常使用倒装语序，as表示“尽管”的意思。 In view of the low­gravity environment，eating is also different in space.Most food is dried or freeze­dried.It’s a luxury to eat fresh food，because fresh produce such as fruit and vegetables can only be delivered to the space station from the Earth every couple of months.Salt and pepper are only in liquid form，so that they will not float away and block the air pipes.However，liquids can’t be easily controlled in space.We must drink water or any other liquids out of a bag through a thin tube of plastic.Furthermore，to keep our body healthy，we must ensure a balanced supply of nutrients by taking pills. Spending some time in the gym is of vital importance to astronauts’ health.Did you know that in just five months，astronauts could lose a significant amount of muscle and bone mass？【9】Considering these negative effects low gravity has on the human body，we discipline ourselves to do at least two hours of exercise every day.Exercise in space is not your average workout.We have to be tied onto specially designed exercise equipment to stop ourselves from floating around. 【9】本句中that引导宾语从句，作谓语动词know的宾语。 During our leisure time，there’s nothing we like more than to sit back with the rest of the crew and watch our remarkable planet go by，taking pictures for our family and friends back home.As the space station travels at a speed of about 17，500 miles per hour，we get to see the sunrise every 90 minutes．【10】 In these precious moments，all the challenges of life in space seem worth it. 空间站的生活 在太空生活是每个未来的宇航员的梦想。我在空间站六个月的停留已经结束，这是一场充满挑战但又神奇的冒险。我敢肯定你一定很想知道太空中的日常生活是什么样子的，以及它与地球上的生活有什么不同——低重力绝对会让普通事情变得奇怪！ 从我们睡觉的那一刻起，在太空生活的陌生感就显而易见了。由于太空中几乎没有重力，我们必须系住自己，这样才不会四处漂浮。我们通常睡在更像是大橱柜的私人睡眠区里，或者睡在挂在墙上或天花板上的睡袋里。试着背部没有压力入睡是奇怪的，但我们不再为这些特别的床而烦恼了。大约8小时的睡眠后，我们开始一天的工作。 占用了一天里大部分时间的日常工作要求很高，但是也会非常有意义。我们的主要任务是进行科学研究。我们需要评估低重力对动物和植物的影响。老鼠、鱼和蚊子等生物也被送到了空间站！在低重力环境下，我们可以在显微镜下更多地了解细胞和微生物的变化。除了做这些生物实验，我们还进行其他研究领域的实验。我一直在做一个在地球上的大片区域定位和追踪闪电的实验。希望它能给地球上的气候带来新的启示，并带来更好的防雷措施。有这么多事情要做，空间站需要很多维护，所以我们经常检查支持系统，做一些清洁工作。 最具挑战性的工作发生在我们需要在空间站之外执行任务的时候，比如测试新设备、监测科学实验或修复空间站。在这种情况下，是时候来场太空行走了。首先，我们穿上太空服，太空服可以让我们在太空中呼吸并且保护我们免受寒冷和辐射。然后我们出发，有时一次要执行几个小时的任务，可以看到下面美丽的地球。虽然地球的景色十分壮观，但太空行走并不像你们可能想象的那么激动人心。这可能是最危险的工作，有诸如电击等潜在的风险。这就是为什么每一次太空行走都是精心策划的。 鉴于低重力环境，太空中的饮食也有所不同。大多数食物是干的或冻干的。吃新鲜的食物是一种奢侈，因为像水果和蔬菜这样的新鲜农产品只能每隔几个月从地球上运送到空间站。盐和胡椒只以液体的形式存在，这样它们就不会漂走，堵塞气管。然而，液体在太空中不容易控制。我们必须通过一根细的塑料管喝袋中的水或任何其他液体。此外，为了保持身体健康，我们必须通过吃药来确保营养的均衡供应。 花些时间在健身房锻炼对宇航员的健康至关重要。你知道仅仅在五个月里宇航员就可能失去相当多的肌肉量和骨量吗？考虑到低重力对人体的这些负面影响，我们要求自己每天至少锻炼两个小时。在太空中锻炼不是一般的锻炼。我们必须被绑在专门设计的运动器材上，以防止自己四处漂浮。 在空闲时间，我们最喜欢做的事就是和其他工作人员一起舒服地坐下来，看着我们非凡的星球从身边经过，拍点照片给地球上的家人和朋友看。由于空间站以每小时17 500英里的速度运行，我们每90分钟就能看到日出。在这些珍贵的时刻，太空生活的所有挑战似乎都是值得的。 一、整体理解 1．The text mainly tells us ________． A．a challenging but magical adventure B．the strangeness of living in space C．the author’s main task on a space station D．the author’s life on a space station 答案：　D 2．Match the paragraphs with the main ideas.
