launched next month.(一颗新卫星将于下个月被发射。);The rocket will be sent into space.(这枚火箭将被送入太空。)否定句:主语 + will not (won’t) be + 过去分词 + 其他例:The satellite won’t be launched tomorrow.(这颗卫星明天不会被发射。)一般疑问句:Will + 主语 + be + 过去分词 + 其他?(肯定回答:Yes, 主语 + will. 否定回答:No, 主语 + won’t.)例:Will the astronaut travel to the moon (这位宇航员将去月球旅行吗?)Yes, he will.(是的,他会。)3. 考点提醒:牢记结构“will be + 过去分词”,注意不规则动词的过去分词(如 send → sent, receive → received);区分主动语态和被动语态,被动语态强调“动作被执行”。2. 情态动词 can / may / must 表推测1. 核心用法:本单元用于推测太空相关的可能性、必要性,三种情态动词语气不同,贴合“探索未知”的主题。2. 具体用法及例句:can:表“可能”,语气较弱,常用于肯定句、否定句和疑问句,指“理论上的可能性”例:There can be life on other planets.(其他行星上可能有生命。);We can’t travel to Mars now.(我们现在不能去火星旅行。)may:表“或许、可能”,语气比 can 委婉,常用于肯定句和否定句,指“不确定的可能性”例:The astronaut may stay in space for a month.(这位宇航员或许会在太空停留一个月。);He may not discover new stars.(他可能不会发现新的恒星。)must:表“一定、肯定”,语气最强,用于肯定句,指“有依据的推测”例:The information must be true.(这些信息一定是真的。);He must be an astronaut.(他一定是一名宇航员。)3. 易错点:must 的否定形式是 can’t(“不可能”),而非 mustn’t(“禁止”);may 的否定形式是 may not(“可能不”),语气委婉。3. 介词 beyond 的用法1. 核心用法:本单元侧重“超出(范围、能力);在……之外”,后接名词或代词,贴合太空探索“超出月球、超出地球”的场景。2. 具体用法及例句:表示“在……之外”(空间范围)例:There are many stars beyond the moon.(月球之外有许多恒星。);Space exploration goes beyond our planet.(太空探索超出了我们的星球。)表示“超出(能力、范围)”例:The task is beyond my ability.(这项任务超出了我的能力范围。);His dream is beyond imagination.(他的梦想超出了想象。)3. 考点提醒:注意 beyond 与 over 的区别,over 侧重“在……正上方”,而 beyond 侧重“超出范围”。Unit7

To keep our earth safe, Chinese scientists are working hard together.Discovered in December, 2024, “2024YR4” is thought to be 40 to 100 meters wide. Although it’s very far away, over 48 million kilometers, Chinese scientists are watching it closely. They want to find more details (细节).________. Chinese scientists plan to make use of special telescopes (望远镜). These telescopes, with powerful cameras and smart software, will help scientists observe (观察) the asteroid clearly, giving them more information to think about ways to stop it if it’s coming too close.To find out the asteroid’s path, China will use supercomputers to learn about its size, shape, speed and the influence of other planets’ gravity (重力) on it. China is working on ways to change the asteroid’s path. They have ideas like sending a spaceship to hit it softly or using a spaceship’s pull to slowly change its direction.China’s big plan shows how much it cares about protecting our planet.

space【练一练】1.A【详解】句意:科学家们将为新的太空项目挑选最好的人选。select选择;fuel燃料;lab实验室;point指向。根据“the best people for the new space project”可知,科学家需要为项目“挑选”人员,select符合语境。2.B【详解】句意:这位勇敢的医生决定用自己的余生为贫穷村庄里的人们服务。stick粘贴、坚持;serve服务、为……效力;mistake弄错;destroy破坏。医生的职责是帮助、服务他人,结合“勇敢的医生、贫穷村庄、余生”的语境,serve最贴合句子的善意与奉献的含义。3.B【详解】句意:当宇宙飞船突然开始摇晃时,他们正在睡觉。while当……时(后接延续性动词,强调两个动作同时进行);when当……时(后接短暂性或延续性动词,可表示一个动作发生时另一个动作正在进行);as当……时(强调伴随或原因);because因为(表示原因)。根据题干主句“were sleeping”是延续性动作,从句“began to shake”是短暂性动作,表示在睡觉过程中突然发生另一动作,应用when引导时间状语从句。4.B【详解】句意:当宇航员正在飞船外工作时,他掉了一个工具。根据主句谓语dropped可知句子基调为过去时。从句引导词While表示“当……期间”,强调背景动作正在进行,因此从句应用过去进行时(was/were + doing)。主语the astronaut为单数,be动词用was。A项为现在进行时,C项为一般过去时,D项为一般现在时,均不符合语境。5.C【详解】句意:——昨晚8点钟你正在做什么?——我正在洗澡。时间状语“at 8:00 last night”提示,句子表示过去某一具体时刻正在进行的动作,时态应用过去进行时,结构为was/were+现在分词。主语是“you”,be动词要用were,do的现在分词形式是doing。6.select/elect【详解】句意:老师将会挑选最优秀的学生参加英语竞赛。根据语境和首字母提示,这里表达老师会“挑选”最好的学生参加英语竞赛,“挑选”对应的英文单词是select,will后接动词原形。7.gym/ym【详解】句意:我们课后经常在学校体育馆打篮球。根据句子“We often play basketball in the school…after class.”的语境,结合首字母g,可知是在学校体育馆打篮球,“体育馆”常见英文表达为gym,所以此处填gym。8.afford/fford【详解】句意:我现在买不起这部昂贵的新手机。根据句子意思“我现在不能……买这部昂贵的新手机”,结合所给答案提示以及常用短语“afford to do sth.”(负担得起做某事),可知此处应填afford。9.seafood/eafood【详解】句意:我们一家人去海边的时候喜欢吃海鲜。根据句子语境“when we go to the seaside”以及所给首字母“s”,去海边的时候喜欢吃海鲜,此处应填“seafood”(海鲜)。10.beef/eef【详解】句意:我爸爸昨天晚餐做了牛肉和面条。根据句子语境“我爸爸昨天晚餐做了……和面条”以及所给首字母“b”,可知此处应填一种食物,beef(牛肉)符合语境。11.fuel【详解】句意:火箭需要大量的燃料才能飞入太空。根据汉语提示可知,fuel“燃料”,不可数名词,在句中作宾语。12.average【详解】句意:我们班学生的平均年龄是14岁。根据汉语提示可知,此处需要填形容词“平均的”,英文单词为“average”。13.hit【详解】句意:这辆车撞到了一棵树上,因为司机当时开得太快了。“碰撞;撞击”对应的英文单词是“hit”,且句子时态为一般过去时,hit的过去式还是hit,所以此处应填hit。14.point【详解】句意:在比赛的某一时刻,我们队一度落后,但最终赢了。 point“时刻”,at one point是固定搭配,表示“在某个时刻、一度”。15.stick【详解】句意:请把这张便条贴在桌上,这样你就不会忘记作业了。“粘;贴”英文为“stick”,本句为祈使句,开头用动词原形。16.satellite【详解】句意:人造卫星为我们提供电视信号和天气预报方面的帮助。“人造卫星”常见的英文表达是“satellite”,helps表明此处用单数形式,此处应填satellite。17.was painting【详解】句意:昨天她的朋友来看她时,她正在画一幅漂亮的画。根据句意和语境可知,“when her friend came”表示过去某一具体时间点,主句描述该时间点正在进行的动作,应用过去进行时;主语She为第三人称单数,故填was painting。18.preferred【详解】句意:当他还是小学生的时候,他更喜欢步行去学校。句中“when he was a primary school student”为时间状语从句,提示动作发生在过去,可判断主句是一般过去时。“prefer”的过去式为“preferred”。19. were doing【详解】原句中“在做什么”是关键词,“做”对应英文“do”,由“at this time yesterday afternoon”可知,句子时态是过去进行时,其结构为“was/were+动词的现在分词”,主语“they”是复数,be动词用“were”,“do”的现在分词是“doing”,所以依次填入“were”和“doing”。20. tie to【详解】原句中“把自己系在墙上”是关键词,表示“把……系到……上”的动词短语是tie...to...,tie为动词,to为介词。本句描述事实,使用一般现在时,主语astronauts是复数,谓语动词用原形tie,to后接the walls。21. was travelling/going【详解】原句关键词为“正在”,表示过去某一时刻正在进行的动作,根据“looked”可知从句使用一般过去时,主句需用过去进行时,即was+现在分词。卫星“运行”可用travelling或going,故填was travelling或was going。22. spread out【详解】原句中“扩展”是关键词,表示“扩展”的动词短语是spread out。本句为不定式短语作表语,to后接动词原形。23. a danger【详解】原句中“构成了巨大的危险”是关键词,表示“一个危险”的名词短语是a danger,be a great danger to意为“对……是一个巨大的危险”。a danger为可数名词短语,在句中作表语。24.B 25.D 26.A 27.C 28.C 29.A 30.D 31.B 32.B

kite意为“手持风筝”,贴合动作逻辑,sell售卖、print印刷、point指向均不符合语境。26.句意:他计划借助火箭的推力飞向天空,再用风筝平安落地。push意为“推力”,符合火箭升空的物理原理,pull拉力、post邮寄、part部分均不符合句意。27.句意:不幸的是,火箭爆炸,他牺牲了。后文是悲剧结局,Unluckily不幸地,契合上下文转折逻辑。Generally通常、Suddenly突然、Nearly几乎均不贴合语境。28.句意:数百年后阿姆斯特朗登月,人类实现了这一伟大梦想。realize a dream是固定搭配,意为“实现梦想”,reduce减少、remind提醒、repeat重复均不符合文意。29.句意:这就是我们总能让世界变得更美好的原因。That’s why...固定句式,用来解释事情发生的原因,贴合上下文因果逻辑。30.句意:袁隆平培育杂交水稻,实现了自己的梦想。invent研发、发明,贴合袁隆平培育杂交水稻的事迹。support支持、burn燃烧、organize组织均不符合人物史实。31.句意:亨利·福特梦想汽车遍布道路,取代马车出行。road道路,贴合车辆通行的场景,streets街道范围过小、oceans海洋、railways铁路均不符合常识。32.句意:梦想十分珍贵,因为它为我们的人生指引方向。direction方向,贴合梦想指引人生前行的内涵,money金钱、journey旅程、keyboard键盘均不符合句意。33.句意:心怀梦想,我们就能制定目标规划,改善当下的处境。present situation意为“当下现状”,ancient古老的、cloudy昏暗的、classic经典的均不贴合语境。34.D 35.A 36.A 37.D 38.B【导语】本文主要讲了小行星“2024YR4”可能在2032年撞击地球,中国科学家正密切观测并制定应对计划以保护地球的故事。34.细节理解题。根据“Discovered in December, 2024, ‘2024YR4’ is thought to be 40 to 100 meters wide.”可知,这颗小行星的宽度在40到100米之间,与一个足球场的大小最接近。故选D。35.推理判断题。根据空后内容“Chinese scientists plan to make use of special telescopes...”可知,这一段开始介绍中国科学家在应对这颗小行星上的具体行动,因此此处是引出中国在其中扮演的重要角色。故选A。36.细节理解题。根据“These telescopes, with powerful cameras and smart software, will help scientists observe the asteroid clearly...”可知,使用特殊望远镜是为了清晰地观测这颗小行星。故选A。37.细节理解题。根据“To find out the asteroid’s path, China will use supercomputers to learn about its size, shape, speed and the influence of other planets’ gravity on it.”可知,超级计算机可以用来了解小行星的大小(a)、形状(e)、速度(c)以及其他行星引力对它的影响(d)。故选D。38.最佳标题题。全文围绕中国科学家为保护地球免受小行星“2024YR4”威胁所做的计划和行动展开,因此最适合的标题是“China’s Plan to Keep Earth Safe from an Asteroid”。故选B。39.D 40.A 41.C 42.F
