Unit 2 I feel good 专题02 语法提升·易错题专项训练 高频易错点03 情态动词Can的用法 高频易错点01 一般现在时的用法 高频易错点02 祈使句的否定形式 高频易错点、易错点提示、小练笔、答题点拨 易错精讲 一般现在时的用法 高频易错点01 一、基本含义 1. 经常性、习惯性的动作或状态，常搭配时间标志词 2. 人物长期不变的情绪、性格、能力 3. 客观事实、普遍真理、固定常态 二、常见时间标志词 every day / every morning, usually, often, sometimes, always, seldom, on Sundays 三、两大句型框架（重点区分：主语三单 / 主语非三单） > 三单主语：he, she, it、单个人名、单数事物 > 非三单主语：I, you, we, they、多个人/多个事物 ① 实义动词句型 ✅ 主语非第三人称单数（I/you/we/they） 肯定句：主语 + 动词原形 例：I feel happy. 否定句：主语 + don’t + 动词原形 例：They don’t feel tired. 一般疑问句：Do + 主语 + 动词原形？ 回答：Yes, 主语 + do. / No, 主语 + don’t. ✅ 主语第三人称单数（he/she/it/Liu Tao） 肯定句：主语 + 动词三单形式(s/es) 例：She feels good. 否定句：主语 + doesn’t + 动词原形 ⚠重点：doesn’t 后面动词必须变回原形！ 例：He doesn’t try hard. 一般疑问句：Does + 主语 + 动词原形？ 回答：Yes, 主语 + does. / No, 主语 + doesn’t. ② be动词句型（am / is / are） 肯定：主语 + am/is/are 否定：主语 + am/is/are + not 疑问：Am/Is/Are + 主语 …? 例：She is happy. → She is not happy. → Is she happy? 四、动词第三人称单数（三单）变化规则【必考】 1. 大多数动词：直接加 s feel → feels ；make → makes ；like → likes 2. 以 s, x, sh, ch, o 结尾：加 es watch → watches；teach → teaches；go → goes 3. 辅音字母 + y 结尾：变 y 为 i，再加 es try → tries；study → studies；worry → worries 4. 特殊不规则变化 have → has 易错点提示 1. does / doesn’t 后面只能使用动词原形，绝对不能用三单！ ❌ Does he feels sad? ✅ Does he feel sad? 2. 只有一般现在时、主语三单才改变动词；过去时、情态动词can后面一律用原形 3. and 在否定句通常要改成 or He can see and hear. → He can’t see or hear. 小练笔 用括号内动词的正确形式填空。 1. My sister often ________ (feel) excited on holidays. 2. They ________ (not feel) tired after playing basketball. 3. How ________ your father ________ (feel) every morning? 4. Reading books ________ (make) me quiet. 5. Liu Tao ________ (try) hard in his PE lessons. 6. Does Nancy ________ (study) English after dinner? 点拨 1. feels解析：主语My sister是第三人称单数；often是一般现在时标志，动词使用三单形式，feel直接加s变为feels。 2. don’t feel解析：主语They是非三单，一般现在时实义动词的否定结构：主语 + don’t + 动词原形，因此填don’t feel。 3. does；feel解析：主语your father为第三人称单数；特殊疑问句结构：疑问词 + does + 主语 + 动词原形，助动词用does，后面动词还原为原形feel。 4. makes解析：动名词短语Reading books作主语，视作第三人称单数，一般现在时动词用三单，make→makes。 5. tries解析：主语Liu Tao是三单；try是以“辅音字母 + y”结尾的动词，变三单规则：变y为i，再加es，即tries。 6. study解析：助动词Does放在句首引导一般疑问句，does后面必须使用动词原形，故填study。 祈使句的否定形式高频易错点02 祈使句概念 1. 用于表达命令、请求、建议、劝告或禁止等的句子 2. 主语“You”通常被省略，一般以动词原形开头 3. 可在句首或句末加上Please表示礼貌 4. 句末用感叹号或者问号，用降调来读 否定祈使句改写 1. Do/Be型否定：句首加Don’t + 动词原形 例：Don’t run in the classroom. 不要在教室奔跑。 2. Let型否定两种写法： Let + 宾格 + not + 动原 / Don’t let + 宾格 + 动原 例：Let’s not watch TV. = Don’t let us watch TV. 易错点提示 1. 祈使句作答规则： 同意：OK. / All right. / Sure. 拒绝：Sorry, I can’t. 后补充无法做到的理由 例：Let’s go shopping. —Sorry, I must finish my homework first. 2.Let后面必须使用人称代词宾格（me/him/her/us/them），不能用主格I/he/she/we 小练笔 用所给动词正确形式填空。 1. ________ (Close) your books, please. 2. Don’t ________ (shout) in the library. 3. Let’s ________ (play) basketball after school. 4. Let ________ (she) sing an English song. 5. ________ (Be) quiet in class. 6. Don’t ________ (eat) in the classroom. 点拨 1. Close解析：肯定祈使句，动词原形开头，首字母大写 2. shout解析：否定祈使Don’t + 动词原形 3. play解析：Let’s 后必须加动词原形 4. her解析：Let 后面用人称代词宾格 5. Be解析：Be型祈使句，Be + 形容词，句首大写 6. eat解析：Don’t后使用动词原形 情态动词Can的用法高频易错点03 can 意为“能够、会、可以”，后接动词原形。常用句型： （1）肯定句：主语+can+动词原形 例：She can play football. 她会踢足球。 （2）否定句：主语+can’t +动词原形 ★注：can not = can’t（缩写）=cannot 例：He can’t dance. 他不会跳舞。 （3）一般疑问句：Can +主语+动词原形？ 回答：Yes, 主语+can. /No, 主语+can’t. 例：—Can you swim? —你会游泳吗？ —Yes, I can. /No, I can’t. —会，我会。/ 不，不会。 易错点提示 can 表示会、能够、可以，后面永远加动词原形，不受人称、单复数影响。 易错点：否定缩写书写错误（can not / can’t / cannot 区分） 1. 口语缩写：can’t（一个n，易错写成cant / can’tt） ❌ cant swim ✅ can’t swim 2. 完整书写两种：can not（分开写）、cannot（合为一个单词，无空格） ❌ can not swim ✅ cannot swim / can not swim 固定搭配否定句结构: 主语 + can’t + 动词原形 例：He can’t play basketball. 小练笔 按要求完成句子。 1.

He can play football.（改为一般疑问句，并做否定回答） ________________________________________ 5.They can swim.（对划线部分提问） ________________________________________ 点拨 1. 答案：can’t see or hear解析：含有can的句子变否定，直接在can后加not，缩写can’t；✅高频考点：否定句里并列连词 and 要改为 or。 2. 答案：can’t talk解析：can变否定直接加’t构成can’t，情态动词后始终使用动词原形talk。 3. 答案：Can you; Yes, I can解析：含有can的陈述句改为一般疑问句，把Can提前；原句主语I，问句要转换为you；肯定回答：Yes, I can。 4. 答案：—Can he play football? —No, he can’t.解析：将Can提到句首，主语he保留，动词用原形play；否定回答用 No, he can’t。 5. 答案：What can they do?解析：划线部分swim是动作，用疑问词What提问；句型结构：What + can + 主语 + do?（do用来替代划线的动作） 综合训练 一、用所给动词的适当形式填空。 1.
