题目性质：自编仿真题——题目、材料、选项、数据与情境均为按课程标准与联招常见考点独立编写的原创仿真题，非真题原文，未取自任何题库、教辅或试卷；解析与采分点为教研整理，非官方评分标准。
一、考点定位与做题顺序
这类空的判断顺序和词义题相反：先看空格两边的形式，再选词。看到后面是 形容词比较级 + than，先问「谁能修饰比较级」；看到 not ___ adj. 且后文有对照，先想同级比较的否定式 not as … as；看到空格后接动词原形且前面有 than，基本锁定 rather than。
三个高频硬规则先摆出来：① very / quite / too / so 不修饰比较级，能修饰的是 far / much / even / still / a lot / a bit；② 不可数名词用 less，可数复数用 fewer；③ 倍数三写法：twice as many as、twice more than（易混，不推荐）、twice what 从句。下面短文为自编示意文本，情境与数据均为示意。
二、逐题精讲
题1
题1 完形填空（五空，单选）
自编短文：Our reading room was refitted last term. The new lamps are (1) brighter than the old ones, yet they use (2) electricity. Ms. Lin said the change was made (3) for comfort than for looks: a reader should be able to stay (4) two hours without eye strain. (5) than buy new shelves, the library simply moved the old ones closer to the windows. By June, evening visits were nearly twice what they had been in March.
(1) A. very B. far C. too D. quite
(2) A. fewer B. less C. little D. least
(3) A. more B. less C. rather D. better
(4) A. as long as B. so long C. longer D. longest
(5) A. More B. Rather C. Other D. Better
解析
(1) B far。空后是brighter than，需能修饰比较级的程度副词；very / too / quite 只修饰原级，far 可修饰比较级，译「亮得多」。(2) B less。electricity 不可数，比较级用 less；fewer 只配可数复数，little 是原级（此处需与前文 brighter 形成对照的比较级），least 是最高级且语意不通。(3) A more。more A than B 表「与其说 B，不如说 A」；此处译「与其说为了好看，不如说为了舒适」，与后句「能连续待两小时不眼疲劳」呼应。C 项 rather 不能直接构成 rather for … than for …（应为 rather than，且后接并列成分），B 项 less 会把语义倒过来。(4) A as long as。as long as + 时间段 表「长达…」，同级比较结构；so long 用于否定句 not so long as，longer 后缺 than，longest 为最高级且不合语境。(5) B Rather。rather than + 动词原形 表「而不是」，与后面 buy（原形，非 buying / bought）严格对应；more than / other than / better than 均无「而非」这一层且搭配不同。
全文回译：上学期阅览室翻新了。新灯比旧灯亮得多，用电却更少。林老师说，这次改动与其说为了好看，不如说为了舒适：读者应当能连续待上两小时而不觉眼疲劳。图书馆没有买新书架，而是把旧书架挪到了靠窗的位置。到六月，晚间到馆人次几乎是三月的两倍。
答案 (1) B (2) B (3) A (4) A (5) B
采分点 每空 1 分：选出答案 0.5 分、写出结构依据 0.5 分；(1)(2)(5) 三空须点明形式依据，只写字母不给满分。
易错点 (1) 选 very（受汉语「很亮」干扰）；(2) 选 fewer（只看中文「更少」，不看名词可数性）；(3) 选 rather（把 rather than 的固定搭配拆开套用）；(4) 选 longer（忽略后面缺 than）；(5) 选 Other（other than 表「除了」，语义不符）。
题2
题2 倍数表达改写（完成句子）
原句：By June, evening visits were nearly twice what they had been in March.
用 as many as 结构改写该句，保持句意不变；并说明 twice more than 为什么不宜用来表达同一意思。
解析
改写：By June, evening visits were nearly twice as many as (they had been) in March.as many as 中第一个 as 是程度副词、第二个 as 是连词，中间用形容词原级 many（因 visits 可数）；倍数词 twice / three times 必须放在第一个 as 之前。
twice more than 字面是「比…多两倍」，按严格理解等于原来的三倍，与 twice as many as（两倍）不等值，考试中属歧义表达，不宜用来替换。稳妥写法只有两种：倍数 + as + 原级 + as 与 倍数 + what 从句。另需注意 twice 不与 times 叠用（不写 twice times）。
答案 改写：By June, evening visits were nearly twice as many as (they had been) in March. 说明：twice more than 按严格理解是三倍，与两倍不等值，属歧义表达。
采分点 改写 2 分（as many as 结构 1 分、倍数词位置 1 分）；歧义说明 2 分（指出倍数差 1 分、给出两种稳妥写法 1 分）。
易错点 写成 twice as many visitors than…（as/than 混用）；把 many 换成 much（visits 可数）；漏掉倍数词位置，写成 as many as twice；把 what 从句误认为定语从句而改写时保留 what。
三、规律小结与对照表
| 结构 | 形式信号 | 可用词／排除词 |
|---|---|---|
| 修饰比较级 | ___ + adj.-er + than | far / much / even / still / a lot；排除 very, quite, too, so |
| 同级比较否定 | not ___ adj. (as …) | as；否定句可用 so，但 so…as 不用于肯定 |
| 数量比较 | 不可数名词 + 比较级 | less；可数复数用 fewer |
| 取舍结构 | ___ than + 动词原形 | rather than；排除 other than（除了）、more than（超过） |
| 倍数 | 倍数 + as + 原级 + as / 倍数 + what 从句 | twice as many as；避免 twice more than 的歧义 |
比较结构题的分数几乎全在「形式」上：先看空格后是原级还是比较级、名词可数不可数、动词是原形还是 -ing，选项往往一眼就能砍掉两个。先定结构、再定词义，比反复读译文省时间。本篇短文、情境、数据与选项均为原创自编示意内容。
四、自测清单
- 圈出空格后的比较级标志 -er / than，先判断谁能修饰它
- 遇名词先判可数性：不可数 less、可数复数 fewer
- 见 ___ than + 动词原形，优先试 rather than
- 倍数词放在第一个 as 之前，中间一律用原级
- 做完后把五个答案代回全文通读一遍，检查语义方向有没有被颠倒
