【分析】
本题考查形容词和副词的比较级用法,解题时需先识别句中的比较级标志(如than、“the + 比较级,the + 比较级”结构),再判断所给词的词性,最后根据比较级的构成规则完成变形。
【解析】
1. 第1题:句中出现比较级标志词than,需用比较级;所给词hard是副词,修饰动词studies,其比较级为harder,故填harder。
2. 第2题:符合“the + 比较级,the + 比较级”的固定句型,修饰动词work需用副词;careful的副词形式是carefully,为多音节副词,比较级加more,故填more carefully。
3. 第3题:同样符合“the + 比较级,the + 比较级”句型;所给词beautiful是多音节形容词,比较级加more,故填more beautiful。
4. 第4题:句中出现than,需用比较级;所给词thin是单音节形容词,重读闭音节结尾,需双写尾字母n再加er,故填thinner。
5. 第5题:此处表示“更便宜的另一件”,需用比较级;所给词cheap是单音节形容词,比较级加er,故填cheaper。
【答案】
1. harder 2. more carefully 3. more beautiful 4. thinner 5. cheaper

【分析】本题考查形容词和副词的比较等级用法,解题时需根据汉语提示,回忆对应的比较结构:原级肯定比较用"as+原级+as",原级否定比较用"not as/so+原级+as";比较级用"比较级+than","得多"用much修饰比较级;"越来越…"用"比较级+and+比较级";年龄差表达用"数词+名词+比较级",结合各小题提示匹配对应短语即可。
【解析】1. 表"和…一样有趣",原级肯定结构为as+形容词原级+as,"有趣"是interesting,故填as interesting as;2. 修饰动词swim用副词well,表"不如…好"的原级否定结构为not as/so well as,故填as well as;3. "冷得多"用much修饰形容词比较级colder,"比"用than,故填much colder; than;4. "更受人喜欢"是多音节形容词比较级,用much more liked,故填much more liked;5. 表"大两岁",用"数词+名词+比较级"结构,故填two years older;6. 表"不如…有趣"的原级否定结构为not so+形容词原级+as,故填not so interesting;7. "一天天好起来"用"比较级+and+比较级",good的比较级是better,故填better and better。
【答案】1. as interesting as 2. as well as 3. much colder; than 4. much more liked 5. two years older 6. not so interesting 7. better and better
