七至九年级原创英语读写课程 · 8年级上学期 · 第6课
适用与边界:按初中知识依赖循序推进,不冒充学校教材的精确单元顺序。全部短文、情境、题目为自编,不含听力。文中的80与95是本课程练习目标,不是中考分数承诺。
学习目标
- 用并列连词连接同等地位的成分或分句。
- 识别原因、结果、时间和条件从句的功能。
- 控制主从句时态并避免中文式重复关联词。
核心讲解
两个完整句子不能只靠逗号粘住
I was tired, I went to bed不是本课要求的规范连接方式;可分句号,或加so:I was tired, so I went to bed。and补充,but转折,or选择或“否则”,so结果。连词连接的成分要平行:She likes reading and drawing,而不是reading and to draw在该并列目标结构里混搭。
从句有自己的主语与谓语,但整体作为主句的一部分。because引原因,when/while/before/after/until/as soon as引时间,if/unless引条件,although/though引让步。先问逻辑关系,再选连词。because与so,although与but在同一主从组合里通常不双用。
未来时间和条件从句常用一般现在时:I will call you when I arrive;If you work carefully, you will make fewer mistakes。主句也可用情态动词或祈使句:If you need help, ask me。并非每个if句都必须出现will。
until表示持续到某时:We waited until five;not...until表示直到某时才:We didn't leave until five。before/after决定两动作先后,as soon as表示一...就...。分句放句首通常以逗号与主句隔开:When the lesson ends, we will clean the board;放后通常不必逗号。长句阅读先找主句骨架,再把条件和时间加回来,不能把限制部分丢掉。

选读脚手架:这段主题阅读用于在语境中复现词汇,不要求初次学习就独立认出所有词。先读后面的中文问题,再找谁、做什么、为什么;未列入词表的难词可查阅或请教师解释,不因出现过一次就计作已掌握。
原创主题短文
Two friends disagree about a group poster. One wants more pictures, while the other wants detailed text. At first, each repeats the same opinion more loudly in the story. Then they write down the purpose: visitors should understand the main idea quickly. They agree to use a clear picture with a short explanation and place extra detail on a second sheet. The solution does not prove that pictures are always better. It fits this audience and this task.
读写示范问题:他们如何从重复立场转向解决问题?为何不是“图片永远最好”?
证据解析与迁移:先明确读者快速理解的共同目的,再安排分层信息;结论只适用本次任务。本文里的listen to作为理解他人意见的词汇,不设音频任务;可用书面留言完成所有讨论。
以上是有解析的教学示范,不另计入独立编号练习;计分任务总数见练习区。
例题解析
例1:Hurry up, ___ you will miss the bus。前句是要求,后句为不这样做的后果,用or“否则”。
例2:I won't open the box until Mum arrives。不是“母亲来以前开”,而是直到到来才开;否定范围必须和until一起读。
例3:Although the task was hard, we finished it。让步表示困难并未阻止结果,不用再加but。
