U2 笔记整理 · 09-18(Grammar:数量比较三组六式 + not as…as 改写)

来源:老师课堂背默笔记(9/18,1 张,编号 1-12)
锚定日 D0 = 09-18:D1 = 09-19、D2 = 09-20、D4 = 09-22、D7 = 09-25、D15 = 10-03、D30 = 10/18
本课定位:U2 Grammar 正课——把 9/16 的"数量比较 + as…as"系统强化为三组六式,并给出 not as…as = 比较级 / less…than 的改写等式。这是江苏中考句型转换题的核心考点,每年必考。
对照:本课早于"预习预测"体系建立,无对应预测;与本课同族的"反义比较级改写"在 10/12 Grammar(比较级最高级)里再次出现。


一、笔记原文逐条对照(12 条)

笔记#中文英文原文红笔标注 / 考点
1比……少(可数)fewer + 复数 + thanfewer + 可数复数;后接 than
2最少的……(可数)the fewest + 复数最高级前必须带 the
3比……少(不可数)less + 不可数 + thanless + 不可数
4最少的……(不可数)the least + 不可数the least(不可数)
5比……多more + n. + thanmore 可数、不可数均可
6最多的……the most + n.the most + 名词
7在午餐时间at lunchtimeat + 时间点
8至少 / 至多at least / at most固定搭配,修饰数词
9休假三天have three days off红笔:have + 时间段 + off(off 是副词)
10请假一周ask for a week offask for + 时间段 + off
11在我们三个人中among the three of us红笔:among 用于三者及以上
12有 100 多年历史 / 数千have a history of over 100 years / thousands of红笔:over = more than;thousands of 表约数

二、高频词精讲(每词带考法)

单词词性中文常考搭配最佳例句
⭐ lunchtimen.午餐时间at lunchtimeWe often chat at lunchtime.(我们常在午餐时间聊天。)
⭐ historyn.历史have a history of + 时间Our school has a history of over 100 years.(我们学校有一百多年历史。)
⭐ hard-workingadj.勤奋的as hard-working asThe students are hard-working.(学生们很勤奋。)
⭐ thousandnum. / n.千two thousand(不加 s);thousands ofThere are thousands of schools in our city.(我们城市有成千上万所学校。)
⭐ offadv.休假;不上学have + 时间 + off;ask for + 时间 + offWe have three days off next week.(下周我们休三天假。)
⭐ amongprep.在(三者以上)当中among the three of usAmong the three of us, Daniel reads the most books.(我们三人中,Daniel 读书最多。)
leastn. / adj.最少(little 的最高级)at least 至少;the least + 不可数Drink at least eight glasses of water a day.(每天至少喝八杯水。)
mostn. / adj.最多(many / much 的最高级)the most + n.;at mostKate has the most stickers of us three.(我们三人中 Kate 贴纸最多。)

三、考点深挖 ① · 数量比较三组六式

3.1 三组六式(本课头号考点)

组比较级(比……)最高级(最……)修饰
few 族fewer + 可数复数 + thanthe fewest + 可数复数可数名词
little 族less + 不可数 + thanthe least + 不可数不可数名词
many / much 族more + n. + thanthe most + n.可数 / 不可数均可
  • → Our school has fewer students than theirs.(我们学校学生比他们少。)
  • → We have less homework than before.(作业比以前少。)
  • → We have more club activities than theirs.(社团活动比他们多。)
  • → Among the three of us, Daniel reads the most books.(我们三人中 Daniel 读书最多。)

3.2 not as / so … as = 比较级改写(红笔两种说法)

原句改写 ①(反义比较级)改写 ②(less … than)
Nancy's school is not as / so big as Tomoyo's.= Nancy's school is smaller than Tomoyo's.—
This book is not as / so interesting as that one.(interesting 无简单反义)= This book is less interesting than that one.

改写规律(中考必背):

  • 原级能"直接反义"(big→smaller,tall→shorter)→ 用反义比较级 + than。
  • 原级是多音节 / -ing 形容词(interesting,boring)→ 用 less + 原级 + than。

3.3 as…as 中的替代词 those / the ones(红笔)

  • as + adj. + as + those / the ones + 地点状语:those = the ones(替代前面出现过的复数名词,避免重复)。
  • → The teachers and students at her school are as hard-working as those at mine.(她校师生与我的一样勤奋。)

四、考点深挖 ② · over / thousand / off / among

4.1 over = more than

  • have a history of over 100 years——over = more than(超过)。
  • 同义替换:over 100 students = more than 100 students。

4.2 数词 + thousand 不加 s;thousands of 表约数

结构规则例句
two thousand students有具体数字 → thousand 不加 sThere are two thousand books.
thousands of students表约数 → 加 s + ofThousands of schools are unusual.

同类词:hundred / million / billion 规则一致(two hundred;hundreds of)。

4.3 have / ask for + 时间段 + off

  • have three days off(休假三天);ask for a week off(请假一周)。
  • off 是副词,时间段直接放中间:have + 数词 + 天 / 周 + off(不接 for)。

4.4 among vs between / at least vs at most

对照区别
among三者及以上当中 → among the three of us
between两者之间 → between you and me
at least至少(≥)
at most至多(≤)

五、教材联动(本课考点在已学课文里早就露过脸)

已学句子出处本课考点
We have fewer students than Class 2.9/16 Readingfewer + 可数 + than——本课把它扩成"三组六式"
Chinese is not as simple as French.9/16 Readingnot as…as——本课给出"改写等式"
The more careful you are, the fewer mistakes you'll make.U1 第一周the + 比较级 + fewer——本课最高级式的源头

为什么 Grammar 课要回头连旧课文:本课不是全新知识,而是把 9/16 的"数量比较 + as…as"系统化成三组六式 + 改写等式。复习本课时把这 3 句再读 1 遍,U1 的比较级 → U2 的同级 / 数量比较就自成体系了。


六、必背句 8 句(分层:基础 5 + 冲 A 3)

基础(笔记原句,默写级)

  1. Our school has fewer students than theirs.(我们学校学生比他们少。)
  2. We have less homework than before, so we have more time for the arts.(作业比以前少,所以我们有更多时间学艺术。)
  3. Among the three of us, Daniel reads the most books.(我们三人中 Daniel 读书最多。)
  4. We had three days off.(我们休了三天假。)
  5. Nancy's school is not as big as Tomoyo's.(Nancy 的学校没有 Tomoyo 的大。)

冲 A(中考式升级句,作文直接用)

  1. This book is not as interesting as that one; in fact, it is less interesting than any book I have read.(这本书不如那本有趣;事实上,它比我读过的任何书都无趣。)—— not as…as + less…than
  2. The teachers and students at her school are as hard-working as those at mine.(她校师生和我校一样勤奋。)—— those 替代复数名词
  3. There are thousands of schools around the world, and our school is one of the oldest with a history of over 100 years.(世界上有成千上万所学校,而我们学校是历史超过百年、最古老的之一。)—— thousands of + one of the + over

七、中考考法速查(3 类题型)

题型考什么解题抓手
单项选择① fewer vs less(可数 / 不可数)② 最高级前 the ③ thousand 与 thousands of看见名词先判可数,再选 fewer / less
句型转换 / 同义句not as big as = smaller than;not as interesting as = less interesting than能反义用反义比较级,不能反义用 less…than
短文填空 / 汉译英at least / at most;have … off;those 替代看见"至少"想 at least;看见"放假"想 have … off

八、抗遗忘复习锚点(U2 Grammar · D0 = 09-18)

节点日期复习重点(从本篇直接取)
D009-18§3.1 三组六式 + §二 高频词(at least / days off / among / thousands of)
D109-19§一 12 条短语首次听写 + §3.2 not as…as 改写
D209-20最高级式(the fewest / the least / the most)+ §3.3 those 替代 + 汉译英
D409-22§3.1 数量比较综合 + §4.2 thousand vs thousands of
D709-25综合默写 + 成段运用(用 Grammar 写"我的学校 vs 别的学校")
D1510-03全单元回滚(§一 12 条 + §七 三题型自测)
D3010/18阶段总复盘

💡 本课是纯语法课(数量比较),复习方式与词汇课不同:优先句型转换(口头)和 fewer/less 填空(笔头),别逐条抄表。
