七至九年级原创英语读写课程 · 9年级下学期 · 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
- 在保持意义的前提下转换时态语态及句型。
- 按句子主干检查冠词、数、一致、非谓语和从句。
- 区分真正错误、可接受变体与风格优化。
核心讲解
改写首先保护原义
主动被动转换保持时间、否定、情态和参与者：They may cancel the trip→The trip may be cancelled；不能把may换will。同义转换too young to join→not old enough to join需改反义形容词；because→because of时，前者接从句，后者接名词/名词短语或动名词：because it rained→because of the rain。
问句转换先判断be/情态/实义动词，再调整。感叹句常见What+(a/an)+形容词+名词(+主语谓语)!，How+形容词/副词(+主语谓语)!：What a useful book! How useful the book is! 不可写How a useful book。反意疑问句基础是陈述肯定→尾问否定、陈述否定→尾问肯定，并匹配助动词：She is here, isn't she? They don't know, do they? Let's...常用shall we，祈使句尾问有语境差异，不作为死记唯一形式。
改错顺序：先找主谓宾是否齐；再看时间语态；再查从句和非谓语；最后处理冠词、介词、名词数、拼写标点。The advice are useful涉及不可数及一致；I look forward to meet涉及介词to；Do you know where is he涉及宾语语序。
不是每个不同于范文的表达都错误。英美拼写organise/organize可并存但一篇宜一致；Some people use...与People sometimes use...可能信息范围不同，不能当机械同义。纠错说明“什么规则在什么语境下”，不要只写语感。

主题阅读与词汇扩展 用英文术语解释句法而不死背名称
以下为同课主题拓展的已讲词条，每条包含本课释义、搭配和原创例句。可遮中文回忆，再改写一个例句；不是要求一次背完，也不冒充官方完整词表。

| subject | 主语 | the main subject | Find the main subject before choosing the verb. |

| conjunction | 连词 | a coordinating conjunction | A conjunction can connect two related clauses. |
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
In a peer review, one student circles the word bags in “The colour of these bags is bright” and suggests changing is to are. Her partner asks her to identify the main subject, not the nearest noun. They draw a line around “of these bags” as a modifier and keep is. The grammar terms are useful because they explain a decision. Naming “subject–verb agreement” without finding the actual subject would not solve the problem.
读写示范问题：这次同伴建议为何不对？术语怎样真正帮助改错？
证据解析与迁移：中心主语colour单数，bags属于修饰短语；术语指向可验证结构才有用，不能只背“一致”名称。迁移We call him Leo中him为object，Leo为complement，二者作用不同。
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：She gave me some advices。advice不可数，改some advice；若强调条数写two pieces of advice。
例2：It is too difficult for me to solve → It is so difficult that I can't solve it。完整从句需it作宾语，不定式结构不重复it。
例3：What an useful tool! 改What a useful tool! useful开头是辅音音素/j/，看读音而非u字母。
练习
作答要求：除填写答案或写句子外，非写作题均补一句简短理由或原文依据；答案中说明/依据的分数正用于这一步。开放写作按所列量表评分，不必另写语法理由。

参考答案与解析
1. G9B06-E01 答案
The trip may be cancelled/canceled. 保留may的不确定，不改will；英美拼写均可。结构6分，意义保持4分。
2. G9B06-E02 答案
We stayed indoors because of the rain. because of接名词短语，不能原样接it rained。转换6分，词性4分。
3. G9B06-E03 答案
The advice is useful. advice不可数，谓语单数。修改6分，可数性4分。
4. G9B06-E04 答案
I look forward to meeting you. 此to为介词，后接doing。修改6分，结构4分。
5. G9B06-E05 答案
Do you know where he is? 宾语从句陈述语序。修改6分，理由4分。
6. G9B06-E06 答案

8. G9B06-E08 答案
is she；don’t they。前否后肯、前肯后否且be/实义助动词分别对应。每项5分。
9. G9B06-E09 答案
visited（last week过去）；shows（museum当前展示事实，或showed置过去叙事也可）；much useful information（不可数）；it is worth visiting（补系动词，worth doing）。每处改正1.5分，解释1分。show不是单靠上一句过去就只有一个可接受时态；需保持自选视角一致。
10. G9B06-E10 答案
示例：Two types of mistakes appeared in my last draft. First, I wrote “Yesterday we visit the museum.” I changed visit to visited because the event was in the finished past. Second, I wrote “Do you know where is the entrance?” I moved is after the entrance because the question contains an object clause with statement word order. These corrections are more useful than copying the complete model answer. In my next draft, I will underline each main verb and draw a line around every clause. Then I will check time references and sentence order before changing small spelling details. 内容4分，改错知识与英语4分，检查方法可执行2分。
学习证据与复习
基础区低于64分：返回本课核心讲解，给每个错误贴上“词义、句法、时间、证据、表达”之一，再不看答案重做。达到基础目标：隔两天用不同主语或情境重新造句。冲刺95：将第9题的证据位置和第10题的修改理由写出来；不要把一次满分当成迁移能力。
前置复习：上一课。
