江苏译林8A新教材期中复习语法讲义4 期中复习专题 04 | 综合提升与错题诊所 涵盖U1—U4；综合任务：语法辨错、情境选择、语篇运用与写作迁移。 01 期中高频陷阱：七类错误一表通 审题时优先检索“比较对象—名词可数性—词性—人称—动词形式”这五个线索。 结构与规则对照 易错类型 错误示例 正确表达与原因 双重比较 more better better：不规则比较级不加more 可数性错误 less students fewer students：students可数 同级比较误用 as taller as as tall as：用原级 形副混用 speak more clear speak more clearly：修饰动词 反身代词误形 by ourself by ourselves：we复数 祈使句多to Don’t to touch Don’t touch：原形 建议句误用 had better not to go had better not go：无to 原创情境例句与解析 1. Our team used the least paint but made the most creative poster. 解析：paint不可数，creative的最高级为most creative。 2. Sam works as steadily as Amy, and both have improved. 解析：steadily副词原级用于as...as。 3. Let’s not hurry; we had better check the parts ourselves. 解析：祈使句、建议句与反身代词组合。 易错点提醒 1. 一题多考时，先找主干，检查名词可数性和词性。 2. 考试答案应兼顾语法正确与上下文逻辑，不能仅靠形式套公式。 3. one of + 最高级+复数名词；of all + 最高级，这些都是常见线索。 02 期中必备：四单元知识框架 以下七个知识块对应教材Grammar内容，可作为考前最后一遍检查表。 结构与规则对照 单元 核心语法 一分钟检查 U1 形容词 比较级 / 最高级 friendlier；the most reliable U2 数量 more / fewer / less；most / fewest / least fewer lessons；less free time U2 同级比较 as / not as(so) ... as as useful as U3 副词 more carefully；better；fastest learn more efficiently U3 反身代词 myself / yourself / ourselves / themselves make it by ourselves U4 祈使句 Do / Don’t / Let’s (not) + 原形 Keep quiet. / Don’t rush. U4 建议 should (not)；had better (not) + 原形 You had better ask for help. 原创情境例句与解析 1. Eva is one of the most reliable teammates in our class. 解析：one of后最高级+复数。 2. The students organised the club themselves and did it more efficiently. 解析：反身代词强调，副词比较级修饰did。 3. Don’t waste paper. You should use both sides. 解析：祈使句与should配合。 易错点提醒 1. 看到than，检查是否已有比较级；看到of all，检查最高级。 2. 看到as...as，检查中间是否为原级。 3. 看到should、had better或Don’t，下一词是否为动词原形。 03 语法专项练习 一、单项选择（每题只有一个正确答案） （ ）1.

Each team chose one problem at school. Some wanted fewer plastic bottles at lunch; others wanted quieter corridors or more places to read. Students researched the issues themselves and made simple posters. During the event, one team said, “Bring your own water bottle. Don’t leave rubbish behind.” Another team offered a guide to safer DIY activities. They advised students to read instructions carefully and said they had better ask an adult before using electrical tools. The school promised to review the suggestions after a month. （ ）1. What did the students investigate? A. Problems around school B. Train tickets C. Sports records D. Family holidays （ ）2. What did students do themselves? A. Build a new hall B. Research issues C. Buy new tools D. Change the school timetable （ ）3. What was suggested for electrical tools? A. Use them secretly B. Never read rules C. Ask an adult first D. Work faster 五、写作迁移（可作为课堂微写作） 以“Small changes for a better school”为题写80—100词英文倡议，尽量展示U1—U4多种语法结构。 参考示例 A better school starts with small actions. We should waste less paper and bring our own bottles. If we organise activities ourselves, we can learn more quickly. Our class can make a reading corner that is as welcoming as the library. Don’t leave rubbish on desks, and please return books on time. The more carefully we work together, the better our school will become. 可迁移表达 语法作用 less paper 不可数名词数量比较 ourselves 反身代词 more quickly 副词比较级 as welcoming as 同级比较 Don’t ... / should ... 祈使句与情态建议 写作提示：学生可以更换人物、学校或活动情境，不必照抄示例。 05 参考答案与解析 一、单项选择 题号 1 2 3 4 5 6 7 8 9 10 答案 C B B B C A A A B A 1.

He answered the questions more correctly than before. 说明：修饰answered用副词correctly。 3. There are as many volunteers as there were last year. 说明：volunteers可数复数。 4.
