2026-2027学年八年级英语上学期考点大通关（人教版新教材） Unit 2 Home Sweet Home核心语法专练 语法一：Could 表示委婉请求（单元重中之重） 1. 句型结构 ① Could you please + 动词原形…? 请你……好吗？（向别人提出委婉请求，日常交际高频） 肯定回答：Sure / Of course / No problem. 否定回答：Sorry, I can’t. I have to… 教材原句：Could you please help me clean my room? 翻译：请你帮我打扫房间好吗？ 解析：could此处不是过去式，只是语气更礼貌，后面必须接动词原形，不能加to。 ② Could I + 动词原形…? 我可以……吗？（请求允许，向别人征求许可） 肯定回答：Yes, you can. 否定回答：Sorry, you can’t. 教材原句：Could I use your computer? 翻译：我可以用一下你的电脑吗？ ⚠易错：回答不用could，要用can。 2. 辨析：could vs can （1）can：直接、口语化，用于熟人之间 （2）could：语气更加委婉客气，不表示过去，向陌生人、长辈求助优先用could 3. 否定句型 Could you please not + 动词原形? 请你不要……好吗？ 例句：Could you please not make so much noise? 请你不要制造这么大噪音好吗？ 语法二：情态动词can 的用法 1. 表示能力：能够、会 例句：I can do many chores at home. 我在家会做很多家务。 2. 表示许可：可以 例句：You can watch TV after you finish your housework. 做完家务你可以看电视。 3. 否定：can’t = cannot 不能；不可以 注意：can / can’t 后面一律接动词原形。 语法三：There be 句型（描述家中房间、物品存在） 1.基本结构 （1）There is + 单数名词/不可数名词（某地有……） （2）There are + 复数名词 教材原句：There is a big sofa in the living room. 翻译：客厅里有一张大沙发。 2.就近原则 be动词单复数由离它最近的名词决定。 例句：There is a table and two chairs in my bedroom. 我的卧室有一张桌子和两把椅子。 3.一般疑问句&否定句 一般疑问句：Is there…? / Are there…? 否定句：There isn’t… / There aren’t… ⚠区分：there be（某地存在有） vs have（某人拥有） ❌There has a bed. ✅There is a bed. 语法四：动词不定式   help sb. (to) do sth. 固定结构 教材原句：I often help my parents (to) do housework. 翻译：我经常帮父母做家务。 解析：help后面的to可以省略，后面用动词原形。 拓展：help with +名词 I help with the housework. 我帮忙做家务。 语法五：并列连词 not only…but (also)… 不但……而且……（单元重点） 1. 含义：不但……而且……，连接两个并列成分 教材原句：Home is not only a house, but also a place full of love. 翻译：家不仅仅是房子，更是充满爱的地方。 2. 主谓就近原则：谓语动词和靠近的主语保持一致。 例句：Not only my parents but also I like doing chores. 不仅我的父母，我也喜欢做家务。 语法六：动词短语 —— do/ make 引导家务短语（考点） 1. do 侧重“做某项工作” do chores 做家务；do housework 做家务；do the dishes 洗餐具 2. make 侧重“整理、制作” make the bed 铺床；make dinner 做晚饭 本单元高频易错汇总 1. Could you please +动词原形，严禁加to 2. Could I…? 的答句用 can / can’t，不用could 3. there be 和 have 不可混用，there be表存在；have表人拥有 4. not only…but also…遵循就近原则 5. help sb.(to) do sth.，to可省略 语法专练 一、单项选择题 1. —Could you please ____ me clean the living room? —Sure.
