In the afternoon, I go swimming. In the evening, I go shopping. I want to buy some pudding. 字母组合“ing”在这里发音/ɪŋ/，如 morning /ˈmɔːnɪŋ/ running /ˈrʌnɪŋ/ swimming /ˈswɪmɪŋ/ 易错点提示 (1)发音要点：短元音 /ɪ/ + 后鼻音 /ŋ/ 舌尖抵下齿，舌根往后抬，堵住鼻腔出气；不要读成 in。 单词结尾的 ing，一般都读 /ɪŋ/。 (2) 错误：把 /ɪŋ/ 读成 /ɪn/（漏掉后鼻音，读成in） ✅ 正确：/ɪŋ/，一定要带出鼻腔鼻音。 例：running 不要读成 “run-in”，是 /ˈrʌnɪŋ/ 小练笔 写出每题画线部分与其他发音不同的单词。 1. I go running and drink water in the morning.                      __________ 2. The children are dancing and singing a song for me.          __________ 3. She likes shopping in the evening with her son.                 __________ 4. My aunt likes swimming and cleaning the room.              __________ 点拨 答案1.drink 2.song 3.son 4.aunt 1.句意：我早上去跑步并喝水。running和morning画线部分发音均为/ɪŋ/，drink画线部分发音为/ɪŋk/。 2.句意：孩子们正在给我跳舞和唱歌。dancing和singing画线部分发音均为/ɪŋ/，song画线部分发音为/ŋ/。 3.句意：她喜欢晚上和她的儿子一起购物。shopping和evening画线部分发音均为/ɪŋ/，son画线部分发音为/ʌn/。 4.句意：我的阿姨喜欢游泳和打扫房间。swimming和cleaning画线部分发音均为/ɪŋ/，aunt画线部分发音为/nt/。 高频易错点02 I want to show them to my friends.（P85） show /ʃəʊ/ 动词，展示；出示；给……看 1. show sb. sth. 把某物展示给某人看 Show me your new pen. 把你的新钢笔给我看看。 2. show sth. to sb. 把某物展示给某人看 Show your new pen to me. 把你的新钢笔给我看看。 ✨转换规则： `show + 人 + 物 = show + 物 + to + 人` 易错点提示 1. show sb. around … 带某人参观……（高频） 例句：I show you around my school. 我带你参观我的学校。 2.show 的名词含义：演出，节目（a show一场演出） 例句：a fashion show 一场时装秀 小练笔 句型转换 1.

Show your robot ______ him. A. to B. for C. at ( )5. My mum ______ me her new coat. A. show B. shows C. showing ( )6. Let’s ______ him around our garden. A. show B. shows C. showing 点拨 1. 答案：Show your kite to me. 解析：show sb sth → show sth to sb，物放前面，人前面加to 2. 答案：Show her the flower. 解析：show sth to sb → show sb sth，人放动词后，不加to 3.答案：B 解析：动词后面用人称宾格me 4.答案：A 解析：show sth to sb固定搭配 5.答案：B 解析：my mum是三单，动词用shows 6.答案：A 解析：Let’s +动词原形 高频易错点03 Yang Ling has a shopping list and wants to buy things with her pocket money.（P87） with 介词，此处意为“用；使用”，后接使用的工具/物品 结构：动词 + with + 工具 write with a pen 用钢笔写字 draw with pencils 用铅笔画画 易错点提示 use 和 with 都可以表示“用”，两者的区别如下： 1. use 动词：句子里作谓语，必须单独当“动作” with 介词：不能单独作动作，只能搭配动词一起表示“用工具” 2. 两者也可以同义转换： use sth. to do sth. 用……做 = do sth. with sth. 我用尺子画画。 动词版：I use a ruler to draw. with 介词版：I draw with a ruler. 小练笔 用 use /with 填空 1.I ______ a pencil to write. 2.Write ______ a pencil. 3.She ______ a knife to cut the cake. 4.Cut the cake ______ a knife. 5.We draw ______ crayons. 6.We ______ crayons to draw pictures. 点拨 答案1. use 2. with 3. uses 4. with 5. with 6. use 1. I use a pencil to write. 解析：句子需要谓语动词，结构 use sth. to do；主语I，动词原形use。句意：我用铅笔写字。 2. Write with a pencil. 解析：已有动词write，后面用介词with加工具。句意：用铅笔写。 3. She uses a knife to cut the cake. 解析：use sth. to do；主语she是第三人称单数，use变uses。句意：她用刀切蛋糕。 4. Cut the cake with a knife. 解析：已有动词cut，介词with引出工具。句意：用刀切蛋糕。 5. We draw with crayons. 解析：已有动词draw，介词with引出工具蜡笔。句意：我们用蜡笔画画。 6. We use crayons to draw pictures. 解析：需要谓语动词，use sth. to do；主语we，用动词原形use。句意：我们用蜡笔画画。 高频易错点04 I want to buy some pudding.（P86） buy /baɪ/ 动词，买；购买， buy sth. 直接买某物 I buy a pen. 我买一支钢笔。 易错点提示 1. buy sb. sth. 给某人买某物 sb. 用人称代词宾格（me / you / him / her / us / them） 例句：I buy her a toy. 我给她买一个玩具。 2. buy sth. for sb. 给某人买某物 ⚠️ 注意：这里介词用 for，不是to！（高频易错点，和show区分开） 例句：I buy a toy for her. 我给她买一个玩具。 转换公式：buy sb. sth. = buy sth. for sb. 例：She buys me a book. = She buys a book for me. 她给我买一本书。 小练笔 同义句转换 1.

Please try it on. 这件衬衫很好看，请试穿一下。 小练笔 单项选择。 ( )1. The dress is nice. Please try ______ on. A. it B. them C. its ( )2. Try ______ the new trousers. A. on B. in C. at ( )3. My sister ______ on her new coat. A. try B. tries C. trying ( )4. These shoes are cool. Try ______ on. A. it B. them C. they 点拨 1. 答案A 解析：dress（连衣裙）是单数物品，用代词it指代。`try it on` 试穿它。 them用于复数；its意思是“它的”，不符合句意。 2. 答案A 解析：固定短语 try on，含义：试穿。 3. 答案B 解析：主语My sister是第三人称单数，一般现在时，动词try要变为tries。 4. 答案B 解析：shoes（鞋子）是复数名词，动词try后面要用宾格them。`try them on`试穿它们。 it指代单数；they是主格，不能放在动词后。 高频易错点06 You can have four pairs for forty yuan.（P88） pair 名词，一双；一对；一副 a pair of + 复数名词（由两个相同部分组成的物品） 常见词：shoes鞋子，trousers裤子，glasses眼镜，socks袜子，jeans牛仔裤 a pair of shoes 一双鞋子 This is a pair of socks. 这是一双袜子。 易错点提示 重点：谓语动词看pair，不看后面的复数名词！ This pair of … 这双/这副 → 单数，动词用三单 This pair of trousers is nice. 这条裤子很好看。 These pairs of … 这些双/这些副 → 复数，动词用原形 These pairs of shoes are cool. 这几双鞋子很酷。 代词指代规则（高频坑！常和try on一起考） 指代 a pair of …，用it； 指代 two pairs of …，用them This pair of shoes is nice. Please try it on. 这双鞋子不错，请试穿它。 These pairs of socks are nice. Try them on. 这几双袜子不错，请试穿它们。 小练笔 用 is / are 填空。 1. This pair of gloves ______ new. 2. These pairs of shoes ______ old. 3. That pair of glasses ______ nice. 单项选择题。 ( )4. I have ______ new trousers. A. a pair B. a pair of C. pair of ( )5. This pair of socks ______ for you. A. is B. are C. be ( )6.
