Unit 4 My Favourite Subject — Section A (Grammar Focus 3a–3d) 知识回顾 / 情景导入 请用所学句型与同伴互问互答，唤醒关于学科与喜好的已知表达。 问句 答句示例 What subjects do you like? I like art and music. What's your favourite subject? I like all subjects, but my favourite is PE. Why do you like this subject? Because it's interesting. 解题思路：先确定问句类型（喜好/原因），再选用 and 并列学科或用 because 说明原因；but 用于表达与前句相对的喜好。 新词与重点词块学习 词块 释义/用法 art and geography 美术和地理（并列学科） favourite subject 最喜欢的学科 have a/an + 学科 + class/lesson 上……课 remember to do sth. 记得去做（未做） remember doing sth. 记得做过（已做） be good at 擅长 listen to music 听音乐 解题思路：本课时核心不在生词，而在连词。先熟记上表词块，它们会反复出现在练习中。 任务练习 3a 观察与归纳 阅读下列句子，判断 and / but / because 分别连接了什么，并填空。 1. We use ”_____“ to give a reason. 2. We use ”_____“ to give another idea. 3. We use ”_____“ to give two different ideas. 解题思路：先读题干的英文释义——give a reason 对应原因 → because；another idea 对应补充并列 → and；two different ideas 对应相反 → but。 参考答案：1. because 2. and 3. but 任务练习 3b 连词匹配 将左右两部分连成合乎逻辑的句子（写出序号搭配）。 左 右 1.

He is good at English, D. and draw pictures. 5. My favourite subject is geography E. but I often walk to school. 6.

I have Chinese, English, geography and music… I like geography and music because they are fun. Wang Hong likes geography as well because she enjoys learning about places. 语言点练习 一、用 have / remember 相关结构完成句子。 1. 我们今天上美术和地理课。We ______ art ______ geography today. 2. 记得把礼物寄给父母。Remember ______ ______ your parents a gift. 3. 我记得和同学在大厅唱过这首歌。I remember ______ this song with my classmates. 解题思路：1 用 have 表”上课“，并列用 and；2 ”记得去做“用 remember to do；3 ”记得做过“用 remember doing。 参考答案：1. have, and 2. to send 3. singing 二、用 and / but / because / so 选择填空。 4.
