九年级英语全册 Unit2 核心知识点汇总人教版 一、必掌握核心单词 (一)高频考点词 relative(n. 亲属;亲戚) 例句:During the Spring Festival, Lucy often visits her relatives with her parents and talks with them in English to practice her speaking. (春节期间,露西经常和父母一起拜访亲戚,并用英语和他们交流以练习口语。) 互动提问:你会在和亲属的哪些交流场景中尝试用英语表达呢? (二)易错提醒词 stranger(n. 陌生人) 正确用法:When traveling abroad, it's not safe to tell personal information to a stranger you just met, even if you communicate in simple English. (在国外旅行时,向刚认识的陌生人透露个人信息是不安全的,即使你们用简单的英语交流。)拓展关联:“stranger” 是可数名词,复数形式为 “strangers”,可与 “talk to”“help” 搭配(talk to a stranger/help strangers), (三)基础必备词 rapidly(adv. 迅速地;快速地) 语境应用:With the help of English learning apps, Tom's English vocabulary has increased rapidly in the past two months. (在英语学习软件的帮助下,汤姆的英语词汇量在过去两个月里迅速增加。) 单词模块分层小练习 语境补全:After joining the English corner, Mary's ability to communicate in English has improved r______(答案:rapidly) 错误找茬:❌ We should be proud for our classmates' English achievements. (提示:将 “for” 改为正确搭配介词,答案:proud of) 词形转换:Our school will hold a big ______(celebrate)for the English Cultural Festival next week.(答案:celebration) 时态应用:My brother ______(not visit)his English pen pal since last year.(提示:“since” 搭配现在完成时,答案:hasn't visited) 句子翻译:我发现和陌生人用英语交流能锻炼自己的胆量和口语能力。(答案:I discovered that communicating with strangers in English can exercise my courage and oral English skills.) 二、必掌握核心短语 (一)prepare for(为…… 做准备) 搭配:prepare for the English exam/prepare for an English party 例句:All the students are busy preparing for the coming English final exam these days. 易错提醒:prepare 后接 “准备的事物” 用 “prepare sth.”,接 “为某事做准备” 用 “prepare for sth.” (如 prepare the English lesson 准备英语课,prepare for the English lesson 为英语课做准备) 反义关联:与 “put off”(推迟)区分, “Don't put off preparing for the English test until the last minute.” 在英语学习中,要提前为考试或活动做准备,不要拖延。 (二)dress up(打扮;装饰) 同义:make up(侧重化妆)、get dressed up(更强调着装打扮) 例句:On Halloween, students usually dress up as cartoon characters and have English games at school.细节强调:dress up 后接 “as” 表示 “打扮成……”,不能直接接人物名称 (如 dress up as a witch,不能说 dress up a witch) 场景应用:在英语主题活动中,你会打扮成哪个角色来增加活动的趣味性呢? 三)be proud of(为…… 自豪) 搭配对比:对人:be proud of sb. (如 be proud of my English teacher)对事 / 成果:be proud of sth.(如 be proud of my English score) 例句:Is your English teacher proud of your progress in speaking? 常见错误:❌ My classmates are proud to our English performance in the show.

(你觉得通过看英语动画片学习英语怎么样?) 常见错误:❌ What do you think about read English novels in your free time? (提示:“of” 后接名词或动名词,改正:reading) (二)表目的句型:“in order to + do sth.” 正确句型:in order to + 动词原形(为了做某事,表目的) 例句:Many students get up early in order to read English aloud in the morning.(很多学生早起是为了早上大声朗读英语。) 同义转换:Many students get up early so that they can read English aloud in the morning.

(示例:We are allowed to use English learning apps in English class.) 四)描述过去与现在对比 句型:“People used to..., but now they...” 正确句型:People used to + 过去的做法(如 learn English from textbooks) but now they + 现在的做法(如 learn English through the Internet) 例句:People used to learn English only from textbooks, but now they can learn English through various ways like online courses and English apps. (过去人们只能从课本上学英语,但现在他们可以通过在线课程和英语软件等多种方式学英语。) 场景仿写:用这个句型描述英语学习方式的变化吧? (示例:People used to practice English only with classmates, but now they can practice English with foreigners online.) 句型模块分层小练习 句型补全:She saves money every month ______ ______ ______ buy an English learning machine.(答案:in order to) 同义转换:We practice English every day so that we can improve our oral skills. (用 “in order to” 改写,答案:We practice English every day in order to improve our oral skills.) 错例改正:Teenagers are not allowed play computer games during English study time. 提示:“be allowed” 后接 “to do”, 改正:Teenagers are not allowed to play computer games during English study time. 场景仿写:你觉得通过听英语广播学习英语怎么样? (答案:What do you think of learning English by listening to English radio?) 场景仿写:过去人们主要通过报纸学英语,但现在人们更多通过手机学英语。 (答案:People used to learn English mainly from newspapers, but now they learn English more through mobile phones.) 四、核心语法 (一)情态动词 can/could/may/might(表能力、许可、推测) 核心逻辑拆解 表能力:can(现在能力)、could(过去能力),在英语学习场景中,可用于描述英语能力的变化 表许可:can/may(现在许可,may 更正式)、could/might(过去许可或委婉请求) 表推测:can't(不可能,否定推测)、may/might(可能,不确定推测) 主题场景应用:在英语交流中,常用这些情态动词表达自己的英语能力或请求许可, 如 can speak English(会说英语)、may use your English dictionary(可以用你的英语词典吗)等。 典型例句 I can understand English movies without subtitles now.(现在我能不看字幕看懂英语电影了。) She could only say a few English words when she was five.(她五岁时只能说几个英语单词。) You may borrow my English storybook for a week.(你可以借我的英语故事书一周。) This English word might have different meanings in different contexts. 这个英语单词在不同语境中可能有不同含义。) 高频易错点错误:❌ He can to sing English songs very well. (改正:can 后接动词原形,去掉 “to”,即 He can sing English songs very well.)正确应用练习:When I was in Grade Seven, I ______(not speak)English fluently, but now I ______(communicate)with foreigners in English. (答案:couldn't speak;can communicate) (二)被动语态(一般现在时、一般过去时) 核心逻辑拆解定义:表示主语是动作的承受者,在英语学习场景中,可用于描述英语学习资源的使用或英语活动的举办。 主语 + am/is/are + 过去分词一般过去时被动语态结构 主语 + was/were + 过去分词常见场景: 英语作业被布置:English homework is assigned by teachers every day. 英语比赛被举办:An English competition was held in our school last month. 易混点区分(主动语态与被动语态转换) 转换规律:主动语态主语(动作执行者) 被动语态 by 短语;主动语态宾语(动作承受者) 被动语态主语主动句:Our English teacher corrects our homework every week.
