Why do you like it? — Because it's useful. 你为什么喜欢它?——因为它有用。 Why does he like history? 他为什么喜欢历史? 三、谈论老师的课 Who is your English teacher? 你的英语老师是谁? When do you have maths? 你什么时候上数学课? Our English class is very interesting. 我们的英语课很有趣。 四、谈论未来的打算 I want to be a singer in the future. 我将来想当歌手。 I'd like to be a scientist. 我想当科学家。 六、语法规则 语法一 连词 because / and / but:说明原因与转折 汉语说"因为……所以……""虽然……但是……",英语只用 because、and、but 其中一个词连接,不能成对出现——这是学生最常犯的错误之一。 1. because:说明原因 because 表示"因为",用来回答 why 提问的句子。汉语的"因为……所以……"在英语里只能留 because,不能再加 so。 I like English because it is useful. 我喜欢英语因为它有用。 — Why do you like PE? — Because it is exciting. 你为什么喜欢体育?——因为它让人兴奋。 连词 作用 例句 because 说明原因 I like it because it is fun. and 并列、递进 I like English and I like maths too. but 转折 I like English, but I don't like maths. 2. and / but:并列与转折 and 表示并列或递进,but 表示转折。 I like music and I can play the guitar. 我喜欢音乐,我会弹吉他。 English is useful, but it is not easy. 英语有用,但不容易。 易错辨析 Because I like it, so I read it every day. √ Because I like it, I read it every day.(或 I like it, so I read it every day.) because 和 so 不能同时用 Although it is hard, but I like it. √ Although it is hard, I like it.(或 It is hard, but I like it.) although 和 but 不能同时用 I like English because it is boring. √ I like English because it is useful. because 前后要说通逻辑 即学即练 1. 填空:I like biology it is interesting. 2. 填空:English is useful, I like it very much. 3. 改错:Because it is fun, so I like it. 4. 把两句连成一句:I like music. I don't like art.(用 but) 答题要点 记牢:because 和 so 二选一,although 和 but 二选一,不能像汉语那样成对出现。 语法二 特殊疑问句:What / Why / Who / When Unit 1 学了"疑问词 + be + 主语"的问句。本单元的谓语是实义动词,问句要用 do / does 帮助,结构不同。 1. 结构:疑问词 + do / does + 主语 + 动词原形 谓语是实义动词时,特殊疑问句要借助 do 或 does。 What subject do you like best? 你最喜欢哪门学科? Why does he like history? 他为什么喜欢历史? When do you have maths? 你什么时候上数学课? 疑问词 问句 答语 What What subject do you like best? I like English best. Why Why do you like it? Because it is useful. Who Who is your English teacher? Ms Gao. When When do you have maths? On Monday morning. How many How many subjects do you have? I have eight subjects. 2. 注意 does 后面的动词要还原 用 does 提问时,后面的动词必须用原形。 Why does he like history? 他为什么喜欢历史? When does she have music? 她什么时候上音乐课? 易错辨析 Why he likes history? √ Why does he like history? 实义动词问句用 does,动词还原 What subject you like best? √ What subject do you like best? 缺助动词 do When does she has music? √ When does she have music? does 后动词用原形 即学即练 1. 对划线部分提问:I like English best.(对 English 提问) 2. 对划线部分提问:He likes history because it is interesting.(对 because… 提问) 3. 改错:Why does he likes history? 4. 连词成句:do, when, have, you, maths (?) 答题要点 先判断谓语是不是实义动词——是实义动词就要用 do / does 提问,而且后面的动词一定用原形。 七、考点突破 一 学科名称与词形 本单元学科词汇多,而且有些词形和读音容易混,是听力与拼写的常考点。 核心学科名称 下面八门学科要能听、说、读、写。 英文 中文 注意 Chinese 语文;中文 首字母大写 English 英语 首字母大写 maths 数学 英式拼写;美式 math biology 生物学 — geography 地理 注意拼写:geo-gra-phy history 历史 — IT 信息技术 两个字母都大写 PE 体育 两个字母都大写 art 美术 — music 音乐 — 易错辨析 I like english. √ I like English. 学科名首字母大写 My favourite subject is geograph. √ My favourite subject is geography. 拼写是 geography 即学即练 1. 写出中文:biology geography IT 2. 改错:My favourite subject is english. 答题要点 学科名和语言名首字母都要大写,这是中考常设的拼写陷阱。 二 good at / good with / good for 辨析 三个短语都是 good + 介词,意思完全不同,中考选择题常考。 三个搭配的分工 介词不同,意思完全不同,要整体记。 I am good at maths. 我擅长数学。 She is good with children. 她很会和孩子相处。 Vegetables are good for your health. 蔬菜对你的健康有好处。 搭配 含义 介词后接什么 be good at 擅长(做某事) 名词 / 动名词 be good with 善于应付(某人/某物) 人 / 事物 be good for 对……有好处 人或事物 be good to 对……友好 人 易错辨析 I am good in maths. √ I am good at maths. 擅长用 at She is good at children. √ She is good with children. 和某人相处用 with 即学即练 1. 填空:My brother is good basketball. 2. 填空:This book is good you. 3. 填空:Our teacher is good us. 答题要点 记住四个搭配的介词:at 擅长、with 相处、for 有益、to 友好。 三 help sb with sth 与 help sb (to) do sth help 的两种搭配是本单元重点短语,也是完成句子题的高频考点。 help 的两种搭配 后面接"事情"用 with,接"动作"用 (to) do。 She often helps me with my English. 她经常帮我学英语。 She often helps me (to) learn English. 她经常帮我学英语。 搭配 后面接什么 例句 help sb with sth 名词(事情) help me with my homework help sb (to) do sth 动词(动作) help me (to) do my homework 易错辨析 She helps me with learn English. √ She helps me with English. with 后接名词 She helps me with do my homework. √ She helps me (to) do my homework. 接动作要用动词 即学即练 1. 填空:He often helps me my maths. 2. 填空:He often helps me (learn) English. 答题要点 看后面是"事情"还是"动作":事情用 with,动作用 (to) do。 四 remember 的用法 remember 后面接 to do 和 doing 意思不同,是中考经典考点。 remember to do 与 remember doing remember to do 表示"记得去做"(事情还没做);remember doing 表示"记得做过"(事情已经做了)。 Remember to bring your book tomorrow. 记得明天带书来。(还没带) I remember meeting him before. 我记得以前见过他。(已见过) 结构 含义 例句 remember to do sth 记得去做(未做) Remember to close the door. remember doing sth 记得做过(已做) I remember closing the door. 易错辨析 Remember closing the door when you leave. √ Remember to close the door when you leave. 还没关,用 to do I remember to meet him before. √ I remember meeting him before. 已见过,用 doing 即学即练 1. 填空:Remember (bring) your homework tomorrow. 2. 填空:I remember (see) the film last year. 答题要点 判断方法:事情做了没有——没做用 to do,做了用 doing。 八、文化小贴士 1. 相关国家与地名 英文 中文 说明 Canada 加拿大 北美洲国家 2. 文化差异 标题 内容 学科设置 英美的中学除必修课外,学生可以自己 choose subjects(选课) 课堂称呼 英美学生通常直接叫老师 Mr / Ms + 姓,不叫 teacher 3. 相关表达 英文 中文 说明 French 法语 来自 France(法国) PE 体育 physical education 的缩写 九、写作指导 任务一 我最喜欢的学科 假设你要向笔友介绍你最喜欢的学科,请写一段话。 要求:1. 写明最喜欢的学科是什么;2. 用 because 说明理由(至少两条); 3. 写一写你的老师和课堂;4. 词数 60 左右。 段落提纲 段落 内容 可套用句型 第一段 点明最喜欢的学科 My favourite subject is …. / I like … best. 第二段 说明理由(because) I like it because it is interesting. / It is useful and I am good at it. 第三段 老师与课堂 Our … teacher is ….
