as ... as 同级、too 太、enough 足够：B2 程度表达三件套

Unit 5 描述与比较，PET 你只会 bigger than；B2 要会同级 as...as、too...to、enough to、not enough。Use of English Part 4 最爱考 so...that ↔ too...to、as...as 倍数改写。

① 这一课怎么学（小白 4 步法）

总用时约 70 分钟，B2 比 A2 多花 10 分钟在「辨析」上，拆成 4 步：

1读（20 分钟）
先看第②③④部分：as...as 同级、too...to、enough 位置、Part 4 so/too/enough 转换。别背，先看懂规则和例句。

2练（20 分钟）
做第⑥⑩部分题目，错了就回头看对应规则，把错因写在错题本上。

3背（15 分钟）
背第⑧部分背诵卡：10 个 B2 必备句型 + 口语模板，背到脱口而出。

4说（15 分钟）
做第⑨部分口语练习，大声读、录下来回听，对标 FCE Speaking Part 2/4。

B2 这一课的小目标学完你要做到三件事：① 正确用 as...as 表同级、too...to 太而不能、enough 足够做；② 做 3 道 Use of English（Part 2/3/4）题型题全对；③ 用英语就这个知识点说 1 分钟，考官挑不出 B1 级别的错误。

② 一图看懂全课（思维导图）

程度三件套 5 大块。先有地图再走路。

同级比较
as ... as / too / enough

→

同级 as...as

as tall as

not as/so...as

→

too 太

too hot to drink

→

enough 足够

old enough to

enough money

→

so...that

so hot that we left

→

Part 4 转换

so...that ↔ too...to

读法：从根出发，5 大块顺序走。每块下面是小节点，全记住你就通关 FCE 这一课。

③ 先认识它：程度三件套是什么

一句话：as...as 表同级（一样），too 表过头（太而不能），enough 表够格（足够做）。三者都是程度表达，B2 写作比较和原因结果全靠它们。

关键位置：enough 放名词前、形容词后（enough money / old enough）；too + 形容词 + to 动原（too tired to walk）；as + 原级 + as（as expensive as，中间永远原级）。

Part 4 高频转换so...that ↔ too...to：It was so hot that we couldnt sleep = It was too hot to sleep。考官就爱考这一句。

as...as 中间用原级✗ as taller as → ✓ as tall as。同级比较中间永远原级，不加 -er。

④ 完整体系：程度结构全表

结构	例句	含义
as + 原级 + as	Shes as tall as her brother.	和…一样
not as/so...as	Its not as cheap as I thought.	不如…
too + 形 + to 动原	Im too tired to continue.	太…而不能
形 + enough + to 动原	Shes old enough to drive.	够格做
enough + 名词	We have enough time.	足够的…
so + 形 + that	It was so cold that we stayed in.	如此…以至于

⑤ 用法场景全解（配图记忆）

场景	例句	记忆点
1 同级	This bag is as expensive as that one.	一样贵
2 不如	Today isnt as/so hot as yesterday.	没那么热
3 太而不能	Coffee is too hot to drink.	too...to
4 够格	Hes old enough to vote.	形+enough
5 如此以至于	It was so good that we went twice.	so...that

enough 位置别放错形容词后（old enough ✓ / enough old ✗）；名词前（enough money ✓ / money enough 口语可但 B2 用前面）。

⑥ 中国学生 5 大高频错误诊断

错误 1：as...as 中间用比较级
✗ as taller as → ✓ as tall as。

错误 2：enough 放形容词前
✗ enough old → ✓ old enough。

错误 3：too...to 加 for
✗ too tired to walking → ✓ too tired to walk（to + 动原）。

错误 4：so...that 漏 that
✗ It was so cold we stayed.（口语可，B2 写全 so...that）。

错误 5：not as...as 用 than
✗ not as cheap than → ✓ not as cheap as。

⑦ FCE 考点与真题演练（Use of English 三题型）

题型	怎么考	应对
Part 4	so...that ↔ too...to; as...as 倍数改写	判断结果是否定
Writing	比较两地/两物	as...as / not as...as 丰富比较
Speaking Part 2	比较两图差异程度	as...as, not as...as 直接用

真题风格演练（FCE B2 出题方式）

真题风格 · FCE Part 4key word transformation：The film was so boring that we left early. → The film was ________ early. (TOO)

too boring to stay / too boring to watch。so...that 否定结果 → too...to。

真题风格 · FCE Part 4key word transformation：Mike is shorter than his sister. → Mike isnt ________ his sister. (AS)

as/so tall as。shorter than = not as tall as。

真题风格 · FCE Part 2open cloze：She isnt old ________ to travel alone — shes only twelve.

enough。not old enough to = 年龄不够。

考场提分提醒Part 4：结果是否定（couldnt/didnt）→ 改 too...to；说不如 → not as/so...as。enough 位置：形容词后、名词前。

⑧ 背诵内容：10 个 B2 必备句型 + 口语模板

每天背 3-4 句，3 天背完。背的时候大声读，边读边想 B2 语境，别死记单词。

FCE Speaking Part 2 程度比较模板

In the first photo, the room looks as tidy as a showroom. In the second, its not as tidy — maybe too messy to find anything. Still, the second person seems relaxed enough to enjoy themselves, which the first person isnt.

⑨ 口语练习：说出来才算会

练习 A · 跟读（2 分钟）

跟着上面背诵卡读 3 遍：第一遍慢读看发音，第二遍正常速度，第三遍不看文字凭记忆说。

练习 C · 挑战 · FCE Speaking Part 2 长话短说（2 分钟）

不看稿，1 分钟比较两张图（轻松 vs 紧张的学习环境），用 as...as、too...to、enough 各一句。

口语评分自查（对标 FCE 四维度）说完后对 4 条：① 语法准确度；② 词汇丰富度（本课 B2 词块）；③ 连贯与衔接（连接词）；④ 发音清晰。四条全过 = 这关过了。

考场示范对话（读熟就能套）

⑪ 记忆口诀与 7 天复习计划

三句口诀
① as + 原级 + as 同级；not as/so...as 不如。

7 天复习计划（配合 FCE Unit 5）

天	任务	自检
第 1 天	背变形/词族表 + 做基础 1-6	全对即可
第 2 天	做进阶 7-12 + 重做错题	错题重做全对
第 3 天	挑战 13-18（含 UoE 三题型）	Part 4 改写拿分
第 4 天	回看考点表，做 1 篇 FCE UoE Part 2/3	本课相关空全对
第 5-7 天	每天口头说 1 分钟本课主题（Part 2 风格）	口语流利不卡壳

B2 考场延伸：本课在 FCE 四张卷里怎么拿分

Reading & Use of English Part 2（open cloze）遇到本课考点，先读整句判断词性与逻辑，再回填；Part 3（word formation）务必先判断空格需要名词、形容词还是副词，再决定加 -tion / -ive / -ly 等后缀；Part 4（key word transformation）必须用上题干给出的大写提示词，改写后保持原意、控制在两到三个词的答案长度。Writing（作文/邮件/文章）里把本课结构和词汇自然嵌入一段，比堆难词更能拿 Grammar 和 Vocabulary 分；每段用一个连接词串起句间逻辑。Speaking Part 2 用本课词做一分钟图片比较，先总述两张图的共同点，再逐项对比并给出个人倾向；Part 4 与搭档讨论时，先回应对方观点再补充，避免只说自己的话。

复习节奏建议：当天先看懂「本质」和「形式表」，再做分层练习的基础 6 题；第二天重做错题并挑战 Part 2/3/4 真题风格题；第三天起每天用本课句型口头造三句，直到不看背诵卡也能流利说出。错题不要只抄答案，要在旁边写出错因（词性、搭配、时态还是介词），考前只看错因清单即可。

小白常见误区再提醒

第一次学 B2 时，最容易犯的错不是不会，而是把 PET 的旧习惯直接搬上来：写作通篇用 and / but / so 连句，口语只会说 very good / very nice，该用名词的地方硬塞一个形容词。请记住，B2 评分看的是「能不能在正确的地方用对形式」，不是「认识多少难词」。一个用对的 however 比三个生僻词更得分。

另一个高频失分点是「中式直译」：把中文意思逐字翻成英文，结果介词、冠词、单复数全错。拿不准的搭配，优先背整句而不是背单词——本页背诵卡里的十句话就是现成语料，先跟读、再脱稿复述、最后换到自己生活里造新句。这样练出来的表达才不会在考场上卡壳。

最后提醒：Use of English 是「写对形式」，不是「写对意思」。Part 3 的空就算猜得出中文意思，填错词性照样不得分。动笔前先用一秒钟判断空格前后需要什么词性，再变形。

一句话自测：合上书你会吗

合上书，用三句话回答：① 本课结构/词族的核心规则是什么？② 最容易写错的一处形式是哪里？③ 我能不假思索说出背诵卡第 1、5、10 句吗？三句都能答出来，这一课才算真正过关；答不出就回到「本质」和「形式表」再看一遍，不要急着往下学。B2 不是靠刷页数堆出来的，而是靠每一课都能用自己的话讲清楚。

考前一周怎么用本页

考前一周不要刷新题，把本页的「三句口诀」「错误清单」「真题风格 3 题」和「背诵卡」过三遍：第一遍看懂规则，第二遍遮住答案重做错题，第三遍只看口诀口述例句。Part 4 key word transformation 尤其要限时练，每题不超过 90 秒，写完对照答案看是否用上了提示词、是否保持原意。

学完本课的标志

能在不看任何笔记的情况下，用本课结构和词汇就本单元主题说满一分钟、写对三句话、做对 Part 2/3/4 各一题，就算达标。

别跳过错题

每道错题都标清错因，考前只看错因清单。
