杨师钰霖英语编制
一、单元核心信息
教材版本:沪教版(牛津版)初中英语 八年级下册
单元序号:Unit 7 Space exploration(太空探索)
单元主题:Space exploration(太空探索),核心围绕宇航员在太空的生活与工作、太空垃圾的危害与应对、中国空间站(天宫)的发展、北斗导航系统(BDS)的功能与应用,以及中国太空探索的重要成就,侧重培养学生用英语描述太空相关事物、表达可能性与不可能性、叙述过去进行的动作的能力。
课标要求:明确本单元考点对应八年级下册英语课标具体条目,能运用过去进行时描述过去某一时刻正在发生的动作,能谈论太空探索相关话题;掌握本单元核心词汇、短语及句型,能理解简单的太空相关说明文,能写简短的太空主题英语短文,提升英语语言运用能力;本单元核心语法(过去进行时)为黔东南州中考中频考点,常结合生活场景、科技话题考查,实现课标与本地考情的衔接。
本地考情适配:结合黔东南州近3-5年中考考情,本单元相关考点考频及考法如下:过去进行时(中频,单选、句型转换题型,占比2-3分)、太空相关核心词汇(高频,完形填空、阅读理解,占比3-4分)、太空主题句型(中频,书面表达、句型转换,占比2分),贴合本地中考实际,为师生精准备考提供方向。
二、单元知识点分层梳理
基础必掌握
核心词汇
- exploration / ekspl re n/(n. 探索),
教材原句:Space exploration is a great challenge for humans.
(太空探索对人类来说是一项巨大的挑战。)
- astronaut / str n t/(n. 宇航员)
教材原句:The astronaut spent six months in space.
(这位宇航员在太空中度过了六个月。)
- space /spe s/(n. 太空;空间)
教材原句:There is no air in space.
(太空中没有空气。)
- station / ste n/(n. 站;空间站),
教材原句:China has its own space station.
(中国有自己的空间站。)
基础句型
- 句型1:What was/were + 主语 + doing + 时间状语?(询问过去某一时刻正在做的动作),
例句:What was the astronaut doing at 9 o’clock last night
(昨晚9点宇航员正在做什么),
翻译:昨晚9点宇航员正在做什么?
- 句型2:主语 + was/were + doing sth + 时间状语.(描述过去某一时刻正在做的动作)
例句:He was doing experiments in the space lab at that time.
(那时他正在太空实验室做实验)
翻译:那时他正在太空实验室做实验。
基础语法
- 语法点1:过去进行时(基础规则)
结构:主语 + was/were + 动词ing形式,时间状语:at 9 o’clock last night, this time yesterday等。
例句:She was watching a space program at 8 last evening.
(昨晚8点她正在看太空节目)
解析:主语she为第三人称单数,用was,后接watch的ing形式watching,结合时间状语at 8 last evening,表过去某一时刻正在进行的动作。
记忆口诀:过去某时正发生,was/were加doing,时间状语来提示,at this time yesterday要记清。
进阶提升
词汇拓展
- 词汇拓展1:explore(动词,探索)→ exploration(名词,探索),搭配:explore space(探索太空),
例句:Astronauts explore space to learn more about the universe.
(宇航员探索太空以更多地了解宇宙)
- 近义词辨析:space vs room(核心区别):space侧重“太空;大范围的空间”,room侧重“房间;小范围的空间”。
例句1:Humans dream of traveling in space.
(人类梦想在太空旅行)
例句2:There is no room for another desk in the classroom.
(教室里没有地方再放一张桌子了)
- 固定搭配:take part in(参加)、look forward to(期待)、in the future(在未来)。
例句3:We are looking forward to the future of space exploration.
(我们期待着太空探索的未来)
句型拓展
- 句型拓展1:While + 主语 + was/were doing sth, 主语 + was/were doing sth.(while引导时间状语从句,表两个动作同时发生)。
例句:While the astronaut was working, his family was watching him on TV.
(当宇航员在工作时,他的家人正在电视上看着他)
转换练习:
The astronaut was working. His family was watching him on TV.(合并为一句)
→ While the astronaut was working, his family was watching him on TV.
解题思路:while引导的从句和主句均用过去进行时,连接两个同时发生的过去动作,注意从句与主句之间用逗号隔开。
语法进阶(核心语法的复杂用法、易错点初步梳理)
- 语法进阶点:过去进行时与一般过去时的区别(考频:中频,考法:单选、句型转换,占比2分)。
规则:一般过去时表过去某个时间发生的、已完成的动作,过去进行时表过去某一时刻或某段时间正在进行的、未完成的动作;
例句:He finished his homework last night.(一般过去时,表动作已完成);He was finishing his homework at 9 last night.(过去进行时,表动作正在进行);
易错提示:不要混淆两种时态的时间状语,“last night”可用于一般过去时,“at 9 last night”只能用于过去进行时。
拓展拔高
词汇拓展
- 熟词生义:space(原义:空间)→ 生义:太空,
例句:The satellite is moving in space.
(卫星在太空中运行。);
联想记忆法:astronaut=astro(星星)+naut(航行者)→ 航行在星星之间的人→宇航员。
- 话题延伸词汇:satellite(n. 卫星)、universe(n. 宇宙)、rocket(n. 火箭)、orbit(n. 轨道),适配书面表达拔高,
例句:The rocket sent a satellite into orbit around the earth.
(火箭将一颗卫星送入地球轨道)
句型拔高
- 高级句型:It was interesting to watch the astronaut doing experiments in space.
(观看宇航员在太空做实验很有趣)
替换普通句型:Watching the astronaut doing experiments in space was interesting.;
解析:用It is/was + 形容词 + to do sth句型,更简洁、高级,适配书面表达提分。
跨单元衔接
- 关联知识点:七年级下册Unit 6 “Daily life”中的一般过去时用法。
衔接点:一般过去时与本单元过去进行时的综合运用。
例句:When I arrived home yesterday, my sister was watching a program about space exploration.
(昨天我到家时,我妹妹正在看一个关于太空探索的节目)
解析:when引导的时间状语从句用一般过去时(arrived),主句用过去进行时(was watching),表一个动作发生时,另一个动作正在进行。
文化拓展
- 文化点:国际太空探索相关常识,具体说明:美国国家航空航天局(NASA)是世界上最著名的太空探索机构之一,成立于1958年,曾成功实施阿波罗登月计划;中国空间站天宫的英文名称是Tiangong Space Station,北斗导航系统英文缩写为BDS,可向全球提供导航服务,贴合八年级学生认知,丰富学科素养。
三、单元重难点分层突破
核心重点
过去进行时的用法
- 核心内容:结构为“主语 + was/were + 动词ing形式”,用于描述过去某一时刻或某段时间正在进行的动作,常与at 9 o’clock last night、this time yesterday等时间状语连用,常结合太空探索场景出题(如“What was the astronaut doing when the spaceship arrived ”)。
- 突破方法(基础版):用简单通俗的语言拆解重难点,“was/were跟着主语变,doing是动词ing形式,记住‘过去某一刻,动作正在做’”,配套教材原句例句,帮助学困生快速掌握。
- 突破方法(进阶版):补充重难点综合运用技巧,总结为“一般过去时表动作已完成,过去进行时表动作正在进行,标志性时间词‘at 9 o’clock last night’‘this time yesterday’必用过去进行时”,适配中等生、优等生。
- 配套例句(基础+进阶):
基础句:She was watching a space show at 8 last night.
(昨晚8点她正在看太空节目。)
进阶句:While my father was reading about space exploration, I was drawing a spaceship.(当我爸爸在阅读关于太空探索的内容时,我正在画一艘宇宙飞船。)
- 专项练习:
基础题:
What ______ you ______ at 9 o’clock last night
(答案:were; doing,解析:根据时间状语at 9 o’clock last night,确定用过去进行时,主语you对应were,后接doing)
提升题:
While I was watching the space show, my brother ______ (do) his homework.(答案:was doing,解析:while引导的时间状语从句,主句和从句均用过去进行时,表两个动作同时发生)
2.太空相关核心词汇及固定搭配
- 核心内容:重点掌握exploration、astronaut、space、station、satellite等核心词汇的词性、词义及固定搭配,如explore space、space station、take part in space activities等。
- 突破方法:采用联想记忆法(如“astronaut=astro+naut→宇航员”),结合例句记忆搭配,避免死记硬背,同时区分易混词汇(如space与room)。
- 配套例句:Astronauts need to take special training before they go to space.
(宇航员在进入太空前需要接受特殊训练)
专项练习
基础题(学困生必做):根据句意及首字母提示填空:
The a______ will go to the space station next month.(答案:astronaut);
提升题(中等生、优等生必做):选择合适的短语填空
(take part in/look forward to):
We are ______ the new space program.
(答案:looking forward to,解析:look forward to 表示“期待”,符合句意;take part in 表示“参加”,不符合语境)
核心难点
过去进行时与一般过去时的辨析
- 易错表现:混淆两种时态的用法,如误将“昨晚9点我正在写作业”译为“I did my homework at 9 o’clock last night.”(正确应为“I was doing my homework at 9 o’clock last night.”);误将“他昨天完成了作业”译为“He was finishing his homework yesterday.”(正确应为“He finished his homework yesterday.”)。
- 突破方法:记住核心区别“一般过去时表完成,过去进行时表进行”,结合时间状语判断,标志性时间词(at 9 o’clock last night等)用过去进行时,普通过去时间(yesterday、last week等)可用于一般过去时,配套对比例句强化记忆。
- 纠错练习:题干:What ______ you do yesterday
A.were B. did C. do)
错误答案:A;正确答案:B;解析:yesterday是普通过去时间,表过去完成的动作,用一般过去时,助动词用did,而非were(were用于过去进行时。
过去进行时的否定句和疑问句结构
- 易错表现:否定句误写为“was/were not do”(正确为“was/were not doing”);疑问句误将doing提前(正确为将was/were提前),如误写为“What doing were you at 9 last night ”。
- 突破方法:拆解结构。
否定句:主语 + was/were + not + doing sth。
疑问句:Was/Were + 主语 + doing sth + 时间状语,结合口诀记忆“否定not加中间,疑问was/were放句首”。
- 纠错练习:
题干:She was not watch TV at 8 last night.(改错)
错误答案:was not watch;正确答案:was not watching
解析:过去进行时的否定句,was/were后接not,再接动词ing形式,watch的ing形式为watching。
四、考情导向突破
高频考点汇总(结合黔东南州近3-5年中考真题)
过去进行时的用法,考频:中频,考法:单选、句型转换,占比2-3分,常结合太空探索、日常生活场景出题;
太空相关核心词汇(explore、astronaut、space station等),考频:高频,考法:完形填空、阅读理解,占比3-4分,侧重考查词汇辨析、固定搭配;
太空主题句型(询问过去某时刻正在做的动作、描述太空事物),考频:中频,考法:书面表达、句型转换,占比2分,侧重考查过去进行时句型的运用。

答案:was doing; told; were talking; came; was drawing
解析:结合时态用法,区分动作是否正在进行,when引导的从句用一般过去时,while引导的从句用过去进行时)
2.书面表达(80词左右):描述你昨晚8点到10点的活动,要求运用过去进行时,至少提到一项与太空相关的内容。
参考范文:Last night, from 8 to 10 o’clock, I was doing my homework first. At 8:30, I was watching a space program on TV. It was about Chinese astronauts working in the space station.

六、易错点汇总与避坑指南
词汇易错:space vs room 混淆。
错误示例:There is no space for another desk.
正确:There is no room for another desk.
正确用法:space侧重“太空;大范围空间”,room侧重“房间;小范围空间”,记忆口诀:“太空空间用space,小处空间用room”。
句型易错:过去进行时疑问句结构错误。
错误示例:What doing were you at 9 last night
正确:What were you doing at 9 last night
正确用法:过去进行时疑问句,将was/were提前至句首,doing紧跟主语后,记忆口诀:“疑问was/were放句首,doing紧跟主语走”。
语法易错:过去进行时与一般过去时混淆。
错误示例:I was finished my homework yesterday.

正确用法:一般过去时表过去完成的动作,用动词过去式;过去进行时表过去正在进行的动作,用“was/were+doing”,记忆口诀:“过去完成用过去式,正在进行was/were+doing”。
搭配易错:look forward to 后接动词原形
错误示例:We are looking forward to explore space.
正确:We are looking forward to exploring space.
正确用法:look forward to 中to是介词,后接动词ing形式。
七、教师备课辅助
教学重难点讲解话术:讲解过去进行时时,可先提问“昨天晚上9点你正在做什么?”,引导学生用英语回答,再引出过去进行时结构,结合教材中宇航员太空工作的场景,让学生用过去进行时描述宇航员的动作,贴合课堂教学场景,降低理解难度;讲解词汇时,结合联想记忆法,帮助学生快速记住核心词汇。
课堂互动设计:小组讨论(5分钟):用过去进行时描述宇航员在太空的一天,每组派1名代表发言,发言内容需包含至少3个动作,教师进行点评和纠正;抢答游戏:出示过去进行时相关题目(如时态辨析、句型转换),学生抢答,提升课堂参与度,巩固知识点。
作业布置建议(分层作业):学困生:抄写本单元核心词汇(10个)、基础句型(5个),完成基础练习题(1-10题);中等生:完成基础+提升练习题(1-18题),背诵过去进行时记忆口诀,整理本单元易错点;优等生:完成所有练习题,写一篇80词左右的太空主题短文,运用过去进行时和高级句型,查阅1个太空相关英文小知识并记录。
