江苏译林新教材8A U2语法讲义 Unit 2 School life | Amount comparisons & as ... as 教材对应：U2 Grammar，教材第26—27页；结合校园课程、社团、作业和午餐时间。 01 数量比较：more、fewer、less与最高级 数量比较先判断名词可数性：课节、社团、学生等属于可数名词；时间、作业量、饮水等通常按不可数名词处理。 结构与规则对照 比较词 名词类型 比较级/最高级功能 原创例句 more / most 可数复数、不可数 更多/最多 We have more clubs than before. fewer / fewest 可数名词复数 更少/最少 Class A has fewer lessons on Friday. less / least 不可数名词 更少/最少 I have less free time on Mondays. the most 可数复数、不可数 范围内最多 This group has the most members. the fewest / least 对应名词类型 范围内最少 May has the fewest books; Tom has the least homework. 原创情境例句与解析 1. Our library has more English magazines than last year. 解析：magazines是可数复数，与more连用。 2. I spend less time on games than my sister. 解析：time不可数，用less。 3. Of the four clubs, the chess club has the fewest members. 解析：members为可数复数，用fewest。 易错点提醒 1. fewer people正确；less people在规范考试语境中通常不用。 2. homework、information、time（表示时间总量）均为不可数名词，不能用fewer修饰。 3. 不要把数量比较与形容词比较混淆：fewer books，而不是more few books。 02 同级比较：as ... as与not as/so ... as 比较两者在某方面是否相同，常用as+形容词/副词原级+as；表示不同时，可以用not as/so...as。 结构与规则对照 结构 含义 原创例句 as + 原级 + as 和……一样…… The new lab is as bright as the old one. not as/so + 原级 + as 不如…… My timetable is not as busy as yours. as many + 可数复数 + as 一样多的可数物 We have as many books as Grade 9. as much + 不可数名词 + as 一样多的不可数物 I have as much homework as Ben. twice as + 原级 + as ……的两倍…… The new hall is twice as large as the old one. 原创情境例句与解析 1. Lily is as interested in science as her best friend. 解析：as...as中间使用原级interested。 2. Our lunch break is not as long as theirs. 解析：否定同级比较表示我方午休时间较短。 3. The school garden has as many trees as the playground. 解析：trees为可数复数，使用many。 易错点提醒 1. as taller as错误，as...as中间必须是形容词或副词原级。 2. not as...as与比较级意义有关：A is not as tall as B ≈ B is taller than A。 3. as much homework as正确，homework不可数，不能换成many homeworks。 03 语法专项练习 一、单项选择（每题只有一个正确答案） （ ）1.

Room A had forty seats but only eight tables, so students sometimes waited to find a place to write. Room B had fewer seats but much more natural light. Many students enjoyed reading there. The school decided to add six tables to Room A and put some plants in both rooms. After the changes, Room A became as comfortable as Room B for quiet reading. Students now spend more time in the library and less time looking for a seat. （ ）1. Why did students sometimes wait in Room A? A. It had too few tables. B. It had no windows. C. It closed early. D. It was too far away. （ ）2. Which room first had more natural light? A. Room A B. Room B C. Both equally D. Neither （ ）3. What changed after the improvements? A. Students stopped reading. B. Room A was closed. C. Room A became as comfortable as Room B. D. Room B lost its tables. 五、写作迁移（可作为课堂微写作） 以“How to make our school life better”为主题写80词建议短文，至少使用两个数量比较与两个同级比较结构。 参考示例 Our class has more reading activities than before, but we still have less free time at noon. I hope the school can provide more quiet seats and fewer unnecessary meetings. A good library should be as welcoming as a classroom. If the lunch break is as long as last term, students will have enough time to read and rest. 可迁移表达 语法作用 more reading activities / less free time 可数与不可数的比较 fewer unnecessary meetings 可数名词数量更少 as welcoming as a classroom 肯定同级比较 as long as last term 比较持续时间相同 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 C C C C A C B C 1.
