Be a child with a colourful dream list. Our dreams will come true at last. 易错点提示 st和ld放在句尾时，通常按其字母组合的常规发音处理，不发生浊化等特殊变化。 · st在句尾发/st/，发音时先发出/s/，再发出/t/的清辅音爆破音。 如：breakfast 早餐 best 最好的 fast 快的；快速地 last 最后的；上一个 must 必须 first 第一的；首先 · ld在句尾发/ld/，发音时先发出对应的元音（如/əʊ/），再发出/l/，最后清晰地发出/d/的清辅音爆破音。 如：child 孩子 cold 寒冷的；感冒 old 年老的；旧的 world 世界 【易错点】st的发音有两种 · st在词首 发音规则：在重读音节开头，且后接元音时，/s/浊化为/z/，读成/sd/（如“stop”发音/sdɒp/）；若后接辅音，则正常发音/st/（如“star”发音/stɑː/）。 常见单词：star（星星）、store（商店）、state（状态/国家）、stage（舞台） · st在词尾 发音规则：通常发音为/st/，不发生浊化（如“fast”发音/fɑːst/）。 常见单词：fast（快速的）、just（公正的）、lost（丢失的）、dust（灰尘的） 小练笔 01 根据图片提示，填写字母组合，补全单词。 1. chi 2. fa 3. breakfa 4. we 5. wor 询问植物组成部分及名称的句型高频易错点02 —Look, a plant has different parts.What are their names?(P16) —They are roots, stems, leaves, flowers, fruits and seeds. 易错点提示 · Look：口语中常用的 “引起注意” 的词，翻译为 “看”。 · a plant has different parts： ①a plant表示一株植物（单数可数名词前加不定冠词 a）； ②has是 have 的第三人称单数形式，表 “有”； ③different parts表示不同的部位。 · What are their names?：这句话用来询问事物的名称，是常见的 “问名称” 句型。their是形容词性物主代词，指代 “a plant's（植物的）”； · 答句中的并列名词：“roots, stems...” 是植物各部位的英文表达，用 and 连接多个并列成分，清晰列举事物。 小练笔 02 root stem leaf flower fruit and seed 询问植物组成部分作用的句型高频易错点03 —What do roots do?(P19) —Roots keep the plant in the ground. They also take in water from the soil. 易错点提示 · 问句 “What do roots do?”： ①疑问词 “What” 对 “作用 / 功能” 提问； ②“roots” 是复数名词作主语，所以助动词用 “do”； ③句末的 “do” 表示 “做（什么）、起（什么作用）”。 · 答句 “Roots keep the plant in the ground”： ①主语 “Roots” 对应问句中的事物； ②“keep...in...” 是固定搭配，意为 “把…… 固定在…… 里”。 · 答句“They also take in water from the soil”： ①“They” 指代前文的 “Roots”； ②“also” 表示 “还、也”，用来补充另一个作用； ③“take in” 是固定短语，意为 “吸收”。 例句：—What do pens do? 钢笔有什么作用？ —Pens help us write words. They also let us take notes easily. 钢笔帮助我们写字，还能让我们方便地做笔记。 经典例题 —What do stems do? (单选题) —They ______ food and water to the leaves. A. carry B. play C. study 点拨 答案：A 【解析】句意：— 茎是用来做什么的？— 它们输送养分和水分到叶子。本题考查动词辨析，A 运送，B 玩，C 学习，A 选项符合句意。故选 A。 小练笔 03 根据图片内容，选择相应的选项，将序号写在横线上。 A．makes seeds B．make food for the plant C．grow up to be plants D．carry food and water to other plant parts E．keep the plant in the ground 方式介词高频易错点04 Some seeds travel with wind.(P22) Some seeds travel by themselves.(P22) Why do they travel in this way?(P23) 易错点提示 by乘坐……，表示交通方式。 by car 开车 by plane/air 坐飞机 by taxi 打车 by subway 坐地铁 by bike 骑自行车 by train 坐火车 on使用每种交通工具。 on a bus 乘坐公交车 on foot 步行（步行只能用on） in使用某种语言、工具。 in English 用英语 in Chinese 用中文 in a taxi 乘坐出租车 with表示使用某种工具或身体某部位。 I can see with my eyes. 我可以用我的眼睛看到。 He eats jiaozi with chopsticks. 他用筷子吃饺子。 小练笔 04 单项选择。 ( ) 1．My family travel ______ three ways.

A．travel; of B．go; in C．travel; with why 和 Because 的用法高频易错点05 Why do they travel in this way?(P24) Because their seeds can stick to people or animals. 易错点提示 一、 why 对原因进行提问，常用于特殊疑问句。why 引导的问句不能用 yes 或 no 回答，必须用原因作答。 注意事项 不能与 so 连用：英语中 because 和 so 是 “天敌”，只能用其中一个连接句子，这是小学阶段的高频易错点。 ❌ ：Because it is rainy, so we stay at home. ✅ ：Because it is rainy, we stay at home. ✅ ：It is rainy, so we stay at home. because 引导的从句可以放在句首或句末：放在句首时，后面需要用逗号与主句隔开； 放在句末时，无需逗号。 例 1：Because the soil is wet, the seed begins to grow. 例 2：The seed begins to grow because the soil is wet. 小练笔 05 单项选择。 ( ) 1．—Why do you like winter? —______ I can play in the snow.
