Unit 6 Then and now（期末知识清单）英语外研版三起五年级下册（新教材）

知识清单·外研版（三起）新教材五年级下册 Unit6 Then and now 知识梳理 知识点拨 【考点一】描述今昔状态 【考点二】实义动词一般过去时 【考点三】There be句型现在时与过去时对比 【考点四】情景交际（询问、描述今昔变化） 【考点五】介词短语固定搭配 考点一：描述今昔状态 本考点是描述事物今昔状态的基础，通过be动词时态变化区分过去、现在，主语单复数决定be动词形式。 核心结构 1.描述过去状态（搭配 ...ago / in the past / yesterday 等过去时间词） 单数 / 不可数主语 + was + 形容词 / 短语 复数主语 + were + 形容词 / 短语 2.描述现在状态（搭配 now / today 等现在时间词） 单数 / 不可数主语 + is + 形容词 / 短语 复数主语 + are + 形容词 / 短语 例句 1.The village was small 20 years ago. Now it is big.（这个村庄 20 年前很小，现在很大。） 2.They were young then. Now they are old.（他们那时很年轻，现在变老了。） 易错点 1.was 搭配单数主语 / 不可数名词，were 搭配复数主语，不可混用； 2.今昔对比句中，前后时态必须和时间标志词保持一致； 3.感官系动词（look/taste/sound）现在时第三人称单数要加s。 记忆口诀 过去单数用 was，复数主语要用 were； 现在单数 is，复数 are，时间标志看仔细。 【大显身手】 一、单项选择 ( )1. My bedroom ______ messy five years ago, but now it ______ tidy. A. is; was B. are; were C. were; are D. was; is ( )2. The roads ______ narrow in the past, but they ______ wide now. A. is; are B. were; are C. was; is D. are; were ( )3. —______ your school life different ten years ago? —Yes, it was quite different. A. Was B. Is C. Were D. Are ( )4. These trees ______ short then. Now they ______ tall and strong. A. is; are B. was; is C. were; are D. are; were ( )5. The food ______ terrible long long ago, but it ______ delicious now. A. are; is B. was; is C. were; are D. is; was 二、判断正 (T) 误 (F)，并改正错误句子 1.I am short three years ago. ( )_______________ 2.The parks were beautiful now. ( )_______________ 3.We were happy yesterday. ( )_______________ 考点二：实义动词一般过去时（规则 & 不规则变化） 本考点用于描述过去发生的动作，分为规则变化、不规则变化，疑问句 / 否定句需借助助动词did。 核心变化规则 1.规则变化 ￮一般动词直接加-ed：work → worked ￮以e结尾加-d：live → lived ￮重读闭音节双写尾字母加-ed：stop → stopped ￮辅音 + y 结尾，变y为i加-ed：study → studied 2.不规则变化（必记） leave→left, get→got, give→gave, make→made, become→became 3.句型规则：did引导疑问 / 否定句时，后面必须接动词原形。 例句： 1.He lived in a small town before.（他以前住在小镇上。） 2.Did you visit your old school last week?（你上周去拜访母校了吗？） 易错点 1.不规则动词过去式无规律，不能随意加ed（错误：leaved /gived）； 2.and连接两个并列过去动作，两个动词都要用过去式； 3.过去时否定结构：主语 + didn’t + 动词原形。 【大显身手】 一、单项选择 ( )1. My grandpa ______ vegetables on the farm when he was young. A. grew B. grow C. grows D. growing ( )2. —Did you ______ photos in the old street? —Yes, I did. A. took B. takes C. take D. taking ( )3. They ______ to the city and ______ new jobs five years ago. A. move; find B. moved; find C. move; found D. moved; found ( )4. The little boy ______ his bag on the ground just now. A. drop B. dropped C. drops D. dropping ( )5. She didn’t ______ TV last night. She read books. A. watched B. watches C. watch D. watching 二、用所给动词的正确形式填空 1.We ______ (play) games together yesterday afternoon. 2.My father ______ (leave) home early this morning. 3.Did your sister ______ (learn) to draw when she was little? 考点三：There be 句型 现在时与过去时对比 There be 表示 “某地有某物 / 某人”，重点考查时态切换和就近原则。 核心结构 1.现在时 There is + 单数名词 / 不可数名词；There are + 复数名词 2.过去时（搭配过去时间词） There was + 单数名词 / 不可数名词；There were + 复数名词 核心规则（就近原则） be动词的单复数，由离它最近的名词决定，和后面其他名词无关。 例句 1.There was a small shop here in the past.（过去这里有一家小店。） 2.There are many flowers and a tree in the garden now.（现在花园里有很多花和一棵树。） 易错点 1.时间词决定时态：in the past / ...ago 用过去时，now / today 用现在时； 2.一般疑问句：把is/are/was/were提前至句首；否定句在be后加not。 【大显身手】 一、单项选择 ( )1. ______ no tall buildings here 15 years ago. A. There is B. There were C. There are D. There was ( )2. ______ a lot of birds in the forest now, but few before. A. There are B. There were C. There is D.

Is there B. Are there C. Were there D. Was there ( )5. Look! ______ a new bookstore near our school. A. There is B. There was C. There are D. There were 二、按要求改写句子（每空一词） 1.There was a lake near the village.（改为否定句） There ______ ______ a lake near the village. 2.There are many buses on the road.（改为一般疑问句） ______ ______ many buses on the road? 考点四：情景交际（询问 & 描述今昔变化） 本考点聚焦日常对话，分为询问变化、描述变化、表达感受三大类，是单元口语核心。 核心交际句型 1.询问变化 —Which changes surprise you most?（哪些变化最让你惊讶？） —How is your hometown different now?（你的家乡现在有哪些不同？） 2.描述变化（经典对比结构） In the past, + 一般过去时句子. Now, + 一般现在时句子. 3.表达感受 ...make (s) our life easier/better.（…… 让我们的生活更便捷 / 美好。） 易错点 1.答语要对应问句，询问 “变化” 需具体说明事物，不能笼统回答； 2.前后句子时态严格区分：过去用过去时，现在用现在时； 3.but 常用于连接今昔句子，表转折对比。 【大显身手】 单项选择 ( )1. —______ makes your life better? —The new subway. It saves lots of time. A. Where B. When C. What D. Who ( )2. In the past, people walked to work, ______ now many people ride bikes.

Now, + 一般现在时句子. 3.表达感受 ...make (s) our life easier/better.（…… 让我们的生活更便捷 / 美好。） 易错点 1.答语要对应问句，询问 “变化” 需具体说明事物，不能笼统回答； 2.前后句子时态严格区分：过去用过去时，现在用现在时； 3.but 常用于连接今昔句子，表转折对比。 【大显身手】 单项选择 ( )1. —______ makes your life better? —The new subway. It saves lots of time. A. Where B. When C. What D. Who ( )2. In the past, people walked to work, ______ now many people ride bikes. A. so B. and C. or D. but ( )3. —What was your classroom like five years ago? —______ A. It is big and bright now. B. There were only ten desks. C. We love our classroom. D. It has new windows now.
