解析

【分析】
首先观察每道题的题干,都出现了比较级的标志性提示词than,说明所有空格都需要填写所给形容词的比较级形式。接下来只需要回忆形容词变比较级的对应规则:单音节形容词大多直接加-er,以不发音e结尾的直接加-r,重读闭音节且末尾只有一个辅音字母的要双写末尾辅音再加-er,以“辅音字母+y”结尾的双音节词要把y变i再加-er,多音节形容词要在前面加more,还有部分特殊的不规则变化形容词需要单独记忆,对照每个所给词的属性就能得出正确答案。
【解析】
1. 句中than提示两者比较,interesting是多音节形容词,变比较级需在前面加more,故填more interesting。
2. 句中than提示两者比较,old是单音节形容词,直接加-er变比较级,故填older。
3. 句中than提示两者比较,nice是以不发音e结尾的单音节形容词,直接加-r变比较级,故填nicer。
4. 句中than提示两者比较,careful是多音节形容词,变比较级需在前面加more,故填more careful。
5. 句中than提示两者比较,big是重读闭音节结构、末尾仅一个辅音字母g,需双写g再加-er变比较级,故填bigger。
6. 句中than提示两者比较,cheap是单音节形容词,直接加-er变比较级,故填cheaper。
7. 句中than提示两者比较,short是单音节形容词,直接加-er变比较级,故填shorter。
8. 句中than提示两者比较,good是不规则变化形容词,其比较级为特殊形式better,故填better。
9. 句中than提示两者比较,easy是以辅音字母+y结尾的形容词,变y为i再加-er变比较级,故填easier。
10. 句中than提示两者比较,healthy是以辅音字母+y结尾的形容词,变y为i再加-er变比较级,故填healthier。
【答案】
1. more interesting 2. older 3. nicer
4. more careful 5. bigger 6. cheaper
7. shorter 8. better 9. easier
10. healthier

解析

【分析】
这道题全部围绕形容词、副词的比较等级相关句型转换,解题思路如下:
1. 首先明确核心转换逻辑:同级比较结构as...as表示“和...一样”,其否定形式not as/so...as表示“不如.../和...不一样”,可以和“A比B更...”的比较级句型做同义互换。
2. 逐题对照原句含义,先把原句的比较关系反过来表述,再数清楚题干给出的空格数量,匹配对应的结构,填入正确的形容词/副词形式即可。比如第一题直接对原句的as...as结构变否定,直接在be动词后加not即可;其余同义句转换都把原句“A比B更XX”反过来转化为“B不如AXX”或者“B比A更反向属性的XX”,对应填出内容。
【解析】
1. 原句是as...as引导的同级比较肯定句,变为否定句直接在be动词is后加not,保留结构as + 形容词原级tall + as,所以填not as tall。
2. 原句含义为“这个箱子比那个箱子重”,转换后句子含义为“那个箱子不如这个箱子重”,对应not as + 形容词原级heavy + as结构,三个空刚好匹配,填as heavy as。
3. 原句含义为“Lucy跑得比Lily快”,转换后句子含义为“Lily跑得不如Lucy快”,对应not as + 副词原级fast + as结构,三个空匹配,填as fast as。
4. 原句含义为“我的包比你的包便宜5元”,转换后反向表述为“你的包比我的包贵5元”,expensive的比较级为more expensive,后接than,三个空匹配,填more expensive than。
5. 原句含义为“红裙子比蓝裙子更漂亮”,转换后反向表述为“蓝裙子不如红裙子漂亮”,四个空对应not as + 形容词原级beautiful + as结构,填not as beautiful as。
6. 原句含义为“他比他妹妹大3岁”,转换后反向表述为“他妹妹比他小3岁”,三个空对应填3/three years younger。
7. 原句含义为“这个房间比那个房间大”,转换后反向表述为“那个房间比这个房间小”,两个空对应形容词small的比较级smaller加than,填smaller than。
【答案】
1. not as tall 2. as heavy as 3. as fast as 4. more expensive than 5. not as beautiful as 6. 3/three years younger 7. smaller than
【知识点】
同级比较as...as,形容词比较级,副词比较级
【点评】
本题是比较等级板块的基础经典题型,核心考察比较级和同级比较否定结构的同义互换,只要掌握两个结构的对应逻辑,注意匹配空格数量、使用正确的原级/比较级形式,就可以轻松完成,适合巩固比较等级的基础用法。

三、翻译句子
1. 今天她看起来比昨天高兴。

4. The more you eat, the fatter you'll get.
5. This problem is more difficult than I
thought.

解析

【分析】
这组翻译题核心考察形容词比较级的相关用法,解题时可以按以下思路推进:1. 先判断句子类型,前3题和第5题是常规的“A比B更……”的两者比较结构,第4题是特殊的“越……就越……”固定比较级句型;2. 先确定句子主语、谓语/系动词,再对应句中的形容词,判断是单音节/多音节形容词,变形为正确的比较级形式,注意多音节形容词要在前面加more构成比较级,修饰比较级表“……得多”可以用much;3. 用than引出对应的比较对象,同时注意时态细节,比如“我原本认为的”是过去的想法要用一般过去时,“你就会变胖”描述未来的结果要用一般将来时,最后组合所有成分检查语法逻辑即可。
【解析】
1. 确定主语为She,感官系动词“看起来”用looks,形容词happy的比较级为happier,用than引出比较对象yesterday,时间状语today放在句末,组合得到句子:She looks happier today than yesterday.
2. 确定主语为Lucy,系动词用is,多音节形容词outgoing的比较级为more outgoing,用much修饰比较级体现“……得多”的含义,than引出比较对象her sister,组合得到句子:Lucy is much more outgoing than her sister.
3. 确定主语为This film,系动词用is,形容词boring的比较级为more boring,than后面用that one指代“那部电影”避免重复,组合得到句子:This film is more boring than that one.
4. 套用固定结构“The + 比较级,the + 比较级”,“吃得越多”对应The more you eat,“你就会越胖”对应the fatter you'll get,组合得到句子:The more you eat, the fatter you'll get.
5. 确定主语为This problem,系动词用is,多音节形容词difficult的比较级为more difficult,than后面接“我过去的想法”用I thought,组合得到句子:This problem is more difficult than I thought.
【答案】
1. She looks happier today than yesterday.
2. Lucy is much more outgoing than her sister.
3. This film is more boring than that one.
4. The more you eat, the fatter you'll get.
5. This problem is more difficult than I thought.
【知识点】
形容词比较级变形,两者比较级句型,the+比较级固定结构
【点评】
本题是形容词比较级模块的基础典型题,覆盖了常规两者比较、比较级程度修饰、特殊比较级句型等核心考点,既考察学生对不同类型形容词比较级变形规则的记忆,也考察学生对语境时态细节的把控,能有效巩固比较级相关的基础应用能力。
