参考答案 + 逐空思路点拨 + 干扰项解析
Passage 1 完整解析
标准答案:1.C 2.A 3.D 4.F 5.B
逐空思路点拨:
1. C 前文提出宇宙充满神秘,后文说明望远镜帮助人类观测肉眼不可及的遥远星体。C 选项总起点明望远镜在太空探索中的重要作用,引出本文核心说明对象,属于中考典型段中主旨引入类设空。
2. A 前句介绍早期望远镜构造简单;A 选项承接上文,说明早期望远镜性能不足,难以开展深空研究,与后文现代高性能太空望远镜形成今昔对比。
3. D 本段围绕哈勃太空望远镜展开;D 选项中It指代哈勃望远镜,交代它被发射环绕地球运行的背景,衔接后文它拍摄大量深空照片、助力科学发现的成果。
4. F 前文说明中国空间望远镜正在筹备之中;F 选项中They指代新一代太空望远镜,说明它们未来将由新型火箭送入太空,对应后文探测系外行星、研究早期太阳系的科研任务。
5. B 前句表明望远镜不能解开全部太空谜题;B 选项通过But进行让步转折,强调望远镜依然可以为人类提供珍贵的太空信息,段尾收束本段观点。
干扰项精准排除: E(大多数老式望远镜仍然可以在太空良好运转),原文无相关信息,属于无中生有; G(人们可以通过现代望远镜直接触摸星星)违背基础科学常识,直接排除。
Passage 2 完整解析
标准答案:1.G 2.E 3.A 4.B 5.D
逐空思路点拨:
1. G 前文介绍宇航员是冒着生命从事科研的受训太空旅行者;G 选项中They指代 astronauts,说明宇航员被送往太空完成各类科研任务,自然引出下文对太空生活、太空工作的介绍。
2. E 前句点明太空生活和地球截然不同;E 选项说明在太空,人们的日常习惯必须彻底改变,后文失重环境下睡觉、吃饭、洗漱的细节正是对本句的举例支撑。
3. A 前文提出太空任务充满挑战;A 选项总述宇航员在太空有繁重的工作任务,后文中做实验、检修设备、太空行走都是具体工作内容,为总分式细节匹配设空。
4. B 前文说明太空任务会遭遇意外危险;B 选项用However转折,表达失败不会磨灭人类的太空梦想,衔接后文科学家优化方案、重新尝试的内容。
5. D 段尾主旨升华;D 选项 “许多年轻人梦想成为宇航员”,引出后文,正是这些追梦人的付出推动人类科学不断向前。
干扰项精准排除: C(所有太空任务都可以毫无风险地完成)表述绝对化,和原文提及的太空风险相互矛盾; F(宇航员在太空生活十分舒适,没有任何麻烦),与原文描写太空生活艰难的文本信息相悖,直接排除。
Passage 3 完整解析
标准答案:1.B 2.G 3.A 4.D 5.E
逐空思路点拨:
1. B 前文人类数十年向太空发射大量卫星与火箭;B 选项But转折,点明这些任务之后遗留了大量废弃物,因果过渡引出 “太空垃圾” 这一核心话题。
2. G 前句对太空垃圾下定义:太空中各类人造废弃物;G 选项进一步列举垃圾的具体形态:报废卫星本体、航天器微小漆皮碎片,对概念进行细节阐释。
3. A 前文Some are brokendown satellites(一部分垃圾来自报废卫星);A 选项Others和Some构成固定并列搭配,说明另一部分垃圾来自老旧火箭碎片,并列梳理太空垃圾来源。
4. D 前文说明科学家正在测试清理太空垃圾的新项目;D 选项提出将使用特殊机械工具完成这项工作,后句They就指代机械工具,介绍工具的设计功能,前后指代闭环。
5. E 段尾对策升华;前文提出太空属于全人类,E 选项呼吁我们尽全力保护太空环境,引出后文目的:守护未来太空任务的安全。
干扰项精准排除: C(太空垃圾对太空旅行完全没有危害),原文明确说明碎片会损毁卫星、威胁空间站安全,和文本事实相反; F(人类已经彻底清除绝大部分太空垃圾),原文仅仅处于方案测试阶段,并未实现大规模清理,事实错误,直接排除。
Passage 4 完整解析
标准答案:1.B 2.A 3.D 4.C 5.G
逐空思路点拨:
1. B 前文介绍人类向火星发射很多漫游车开展科学任务;B 选项中These rovers完成指代,说明漫游车没有宇航员随行,属于无人设备,与后文unmanned machines关键词复现。
2. A 本空为段首主旨句;后文罗列拍照、采集土壤样本、研究火星地质等一系列科研活动;A 选项总领全段,概括漫游车在火星开展重要科研工作。
3. D 前句提出漫游车登陆火星绝非易事;D 选项解释登陆需要高端科技与周密筹备,承接后文微小失误就会造成整个任务失败的论述。
4. C 前句部分漫游车实际工作时长超出科学家预期;C 选项They指代 rovers,说明它们已经在火星上连续工作数年,为后文转折:最终会因火星恶劣环境停止工作做铺垫。
5. G 前句表明漫游车仅仅是第一步;G 选项点明漫游车的价值:为未来人类火星旅行铺路,段尾总结,呼应后文载人航天器登陆火星的畅想。
干扰项精准排除: E(无人漫游车可以直接把人类送往火星),原文说明漫游车仅做探测,为载人任务打基础,不能搭载人类; F(所有漫游车都可以在火星表面永久工作),和原文 “大部分终将停止工作” 信息冲突,直接排除。
Passage 5 完整解析
标准答案:1.A 2.B 3.E 4.D 5.C
逐空思路点拨:
1. A 前文列举青少年的航天爱好:空闲时间用望远镜观测星空;A 选项Some even递进,介绍部分青少年参与航天主题营地与活动,和上一句Some构成并列句式。
2. B 前句提出观点:不必成为宇航员,也可以参与太空探索;B 选项说明可以通过多种多样的方式做出贡献,后文设计工具、科普宣传就是对观点的实例支撑。
3. E 前句讲到太空科学需要大量知识储备;E 选项点明青少年可以学习不同理科科目积累相关能力,后句列举数学、物理、生物,前后逻辑匹配。
4. D 前句你的航天梦想此刻看似遥不可及;D 选项But转折,宏大梦想都始于点滴的努力与学习,引出下文学习科学、参加社团这类具体小行动。
5. C 段尾主旨收束;人类太空探索是漫长征程;C 选项呼吁即便梦想艰难,也要坚守航天梦想,完美衔接文末 “坚守梦想,终有所成” 的全文呼吁。
干扰项精准排除: F(只有宇航员可以为太空探索做贡献),原文明确普通人也可以贡献力量,和文章主旨相悖; G(青少年年纪太小,完全不能学习任何太空科学知识),全文鼓励青少年了解航天,观点消极错误,直接排除。
