A. Is B. Am C. Are ( )2. She ______ thin. She's fat. A. is B. isn't C. not ( )3. —Is Mike quiet? —Yes, ______. A. he is B. he isn't C. she is ( )4. ______ your friend kind? A. Is B. Am C. Are ( )5. He ______ short. He's tall. A. is B. isn't C. not have /has 人称与句型转换 高频易错点02 1. have/has 本单元用来描述人物拥有的外貌特征（长头发、大眼睛等），含义为“拥有、长有”。 2. 人称搭配规则：第一人称 I、第二人称 you、复数主语 we/they 统一用原形 have；第三人称单数 he/she/单个人名用三单形式 has。 3. 一般疑问句变换：借助助动词 Does 放句首，后面的 has 必须还原为原形 have； 4. 否定句变换：借助 don't（I/you/we/they）、doesn't（he/she/人名），后面动词统一还原 have。 5. 核心句式例句：She has long hair. / Does she have long hair?（P16） 易错点提示 1.Does 引导疑问句时，后面动词只能用 have，严禁写 has； 2.三单主语陈述句用 has，复数/一二人称用 have，不可混用； 3.have 表拥有时，否定不能直接在后面加 not，必须搭配助动词 don't/doesn't。 小练笔 02 单项选择 ( )1. ______ she have long hair? A. Does B. Do C. Is ( )2. He ______ short hair. A. have B. has C. do ( )3. I ______ a new friend. A. has B. have C. does ( )4. Does Zhang Peng ______ big eyes? A. has B. have C. is ( )5. She doesn't ______ thin hair. A. has B. have C. is 一般现在时动词第三人称单数（read/play/help 变形）高频易错点03 1. 本单元描述朋友日常行为的句型为：主语 + often + 动词短语，属于一般现在时。 2. 动词三单变化规则：主语是 he/she/单个人名（三单主语），动词词尾直接加 s；主语为 I/you/we/they，动词保持原形不变。 3. 单元核心动词变形：read→reads、play→plays、help→helps，无特殊 es 变形，直接加 s。 4例句：He often reads books. / She often helps me with English. 易错点提示 1.看到 often/always 不改变三单变化规则，三单主语动词必须加 s； 2.易丢分：忘记给动词加 s；不存在 reades、playes 这类错误变形； 3.I、we、they 后面动词永远用原形，不需要变形。 小练笔 03 选词填空 read play help 1. He often ______ books after school. 2. She ______ football with her friends. 3. Mike ______ me with my Chinese. 4. I often ______ games after class. 5. They ______ storybooks every day. his /her 物主代词区分高频易错点04 1. his、her 是形容词性物主代词，后面必须搭配名词（name、bag、hair 等），用来表示“……的”。 2. 对应人称区分：男性人物（he/Tom/Wu Binbin）搭配 his；女性人物（she/Sarah/Chen Jie）搭配 her。 3. 人称代词 vs 物主代词区分：he = 他（主语）、his = 他的；she = 她（主语）、her = 她的。 例句：His name is Zhang Peng. / Her name is Sarah. 易错点提示 1.名词前必须用 his/her，不能直接用 he/she 修饰 name/bag； 2.男女人物对应物主代词不能混淆，男孩用 his，女孩用 her； 3.he、she 只能放在句首单独做主语，不修饰物品名词。 小练笔 04 单项选择 ( )1. Sarah is a girl. ______ bag is pink. A. His B. Her C. She ( )2. Tom is a boy. ______ hair is short. A. Her B. His C. He ( )3. ______ name is Chen Jie. She's quiet. A. Her B. His C. She ( )4. ______ name is Wu Binbin. He's strong. A. Her B. His C. He ( )5. Is this ______ pencil? It's Mike's. A. her B. his C. she 特殊疑问句语序（What's/Who's 句型改写）高频易错点05 1. What's = What is，用于询问人名、事物名称，核心句型 What's your friend's name?，用来询问对方朋友的名字。 2. Who's = Who is，用于询问人物身份，核心句型 Who's your best friend?，用来询问谁是你最好的朋友。 3. 特殊疑问句固定语序：疑问词放句首，后接 be 动词，再接主语。 4. 同义改写：What's his name = What is his name；Who's your friend = Who is your friend； 易错点提示 1.询问名字固定用 What's，不能用 Who；询问人物身份固定用 Who's； 2.单数名词搭配 is，不可写成 What are / Who are； 3.不能遗漏缩写里的 is，不能单独写 What / Who 放句首。 小练笔 05 单项选择 ( )1. ______ your friend's name? A. What's B. What C. Who ( )2. ______ that tall boy? A. Who's B. Who C. What ( )3. What ______ his name? A. is B. are C. am ( )4. Who ______ your best friend? A. is B. are C. am ( )5. ______ her name? Her name is Amy. A. What's B. Who's C. Where's 单句改错（三单漏 s、have/has、介词）高频易错点06 1. 动词三单错误：he/she/人名作主语，often 后的动词未加 s，例 He read → He reads。 2. have/has 混用：Does 引导问句后误用 has，必须还原为原形 have。 3. 固定介词搭配：help sb with + 科目，固定介词为 with，不能换成 to。 4. 物主代词混用：用 he/she 修饰名词 name/hair，应替换为 his/her。 易错点提示 1.看到 Does 立刻检查后面动词是否为原形 have； 2.help 搭配介词错误：help me to English 是错的，正确搭配为 help me with English； 3.名词前修饰词只能用 his/her，人称代词不能修饰物品。 小练笔 06 划出错误并改正 1. He often read books after school. 2. Does she has long hair? 3. She help me with my Chinese. 4. He name is Zhang Peng. 5. I help him to English. 同义句式改写高频易错点07 1. be 动词缩写改写：He is = He's；She is = She's，两种写法句意完全一致（P16）。 2. 姓名句型互换：His name is Mike = Mike is his name，主语位置互换，含义不变（P86）。 3. 频度副词位置改写：often 可放在主语后动词前，也可放在句末，如 She often plays football = She plays football often（P19）。 4. 陈述句与一般疑问句互改：be 动词提前可改为问句，be 动词放回主语前可还原陈述句。 易错点提示 1.缩写 's 不能丢失，He is 不能直接简写为 He； 2.人名作主语时，后面谓语动词依旧用单数 is； 3.often 调换位置不改变动词三单变形。 小练笔 07 按要求改写句子 1.
