Unit 2 Get to know the weather 专题02 语法提升·易错题专项训练 · 内容导航 · 1.句型：一般疑问句 2.名词变天气类形容词 3.情态动词can的用法 4.综合训练 高频易错点、易错点提示、小练笔、答题点拨 易错精讲 句型：一般疑问句高频易错点01 在本单元出现了两种一般疑问句的句型： Is it cold in Harbin? 现在哈尔滨冷吗？(P14) Do you like rainy days, Baobao? 宝宝，你喜欢下雨天吗？(P16) 现在我们就来总结一些一般疑问句相关的知识点。 一、一般疑问句的特点 1. 用Yes或No回答的疑问句。 2. 句首有助动词（do/does/is/are/can等），语序需倒装。 3. 句末用问号（?）。 二、常见句型分类与例句 1. 含be动词（is/are/am） 结构：Be动词 + 主语 + 其他？    例句：—Is she a teacher?（她是老师吗？） —Yes, she is. （是的，她是。） —Are you happy?（你开心吗？） —No, I’m not.  （不，我不开心。） 2. 含实义动词（需要借助do/does） 结构：Do/Does + 主语 + 动词原形 + 其他？    例句：—Do you like apples?（你喜欢苹果吗？） —Yes, I do. （是的，我喜欢）  —Does he play football?（他踢足球吗？） —No, he doesn’t.  （不，他不踢。） 三、回答技巧 1. 肯定回答：Yes, 主语 + 助动词.     （例：Yes, I do. / Yes, she is.）   2. 否定回答：No, 主语 + 助动词 + not.     （例：No, they don’t. / No, it isn’t.）   注意：助动词需与问句保持一致（如问句用Does，回答用does）。  易错点提示 1. 不要漏掉助动词：     ❌ You like ice cream? → ✅ Do you like ice cream?   2. 主语是第三人称单数时用does：      ❌ Do she sings well? → ✅ Does she sing well?   3. 缩写形式：isn’t = is not, aren’t = are not, don’t = do not, doesn’t = does not.   经典例题 【例1】—Are the pens under the desk? (单选题) —______ A．Yes, they are. B．Yes, it is. C．No, it isn’t. 【例2】—______ your sister like Chinese? (单选题) —Yes, she ______. A．Do; do B．Does; does C．Is; is 点拨 【例1】答案：A 【解析】句意：—钢笔在桌子下面吗？—____。本题考查be动词引导的一般疑问句及其回答。问句主语是复数the pens，回答时需用复数代词they指代。B、C选项中it用于单数主语，不符合；A选项Yes, they are.符合语法和语义要求，故选A。 【例2】答案：B 【解析】句意：—你的姐姐喜欢语文吗？—是的，她喜欢。本题考查助动词和一般疑问句的答语。like是实义动词，用助动词提问，your sister是第三人称单数，用does提问，does提问does回答，选项B符合题意，故选B。 小练笔 01 一、单项选择。 ( ) 1．—Is this a cow? —_______.

Let’s make a snowman. 2．It’s hot and (sun) today. 3．It’s cool and (wind). Let’s fly kites outside. 4．I like (rain) days. I can read books at home. 5．It looks that the weather can become (cloud), Helen. 情态动词can的用法高频易错点03 We can play in the rain. 我们可以在雨中玩耍。(P16) 情态动词，本身没有词义，不能单独作谓语，一般与实义动词一起构成谓语，表示说话人的态度，没有人称和数的变化。 含有情态动词can的句型 句型 结构 例句 肯定句 主语 + can + 动词原形 He can swim.他会游泳。 否定句 主语 + can't + 动词原形 She can't drive.她不会开车。 一般疑问句 Can + 主语 + 动词原形? Can you help me?你能帮我吗？ 特殊疑问句 疑问词 + can + 主语 + 动词原形? What can I do?你能做什么？ 口诀技巧 “我”是情态动词can，若表能力“我”承担。 不管主语怎么变，“我”的模样都不变动词原形站后边。 一般疑问句“我”提前，否定句“我”后not添学好“我”很简单。 易错点提示 1. can 是情态动词，后面必须跟动词原形，不管主语是不是三单： ❌ He can plays football. / She can dancing. ✅ He can play football. / She can dance. 2. can无人称和数的变化，不会变成 cans/can'ts ❌ She cans swim. / They cans sing. ✅ She can swim. / They can sing. 3. can 本身可引导疑问句 / 否定句，不需要和 be/do/does 重复使用 ❌ Do you can ride a bike? / Is he can draw? ✅ Can you ride a bike? / Can he draw? 经典例题 改错题。 【例1】But my mum cans. 【例2】You can to make a chart. 点拨 【例1】答案：cans改为can 【解析】句意：但是我妈妈会。本题考查情态动词，can会，不加s，故答案为C，can。 【例2】答案：to make改为make 【解析】句意：你会制作表格。此题考查情态动词后加动词原形，故答案为to make改为make。 小练笔 03 一、单项选择。 ( ) 1．She can sing.
