A．The fewer; the more B．The more; the fewer C．The more; the less D．The less; the more 【答案】B 【详解】句意：你越仔细，犯的错误就越少。 考查形容词比较级的用法。“careful”的比较级是“more careful”；“mistakes”是可数名词复数，“少”用“fewer”修饰。句子表达“你越细心，犯的错误就越少”，符合“the+比较级，the+比较级”结构。故选B。 形容词与副词的最高级 当进行三者或三者以上事物比较时，可以用形容词或副词的最高级形式来表示。 1. 比较级的构成规则 (1) 一般在词尾加-est：tall--tallest；long--longest (2) 以不发音的e结尾，直接加-st：nice--nicest；huge--hugest (3) 重读闭音节的单词，当词尾只有一个辅音字母时，要先双写最后一个辅音字母，再加-est：fat--fattest；big--biggest；hot--hottest (4) 以辅音字母+y结尾的双音节词，将y改为i，再加-est：busy---busiest；heavy--heaviest 注意： dry的比较级为driest shy的比较级为shyest (5) 部分双音节词和多音节词在其前面加most构成比较级：beautiful--most beautiful；popular--most popular 注意： 以-y；-ly等后缀构成的双音节派生词和以形容词前缀un-开头的三音节词，末尾加-est构成比较级：friendly--friendliest；healthy--healthiest；unhappy--unhappiest；lovely--loveliest 以加-ing；-ed；-ful；-ous等后缀构成的派生词在单词前加most构成比较级：helpful--most helpful；tired--most tired；famous--most famous (6) 不规则变化： good/well--best；bad/badly/ill--worst；many/much--most；little--least；far--farthest/furthest；old--oldest/eldest 注意： oldest即可以修饰物，也可以修饰人；eldest只表示“年龄最老的”。 2. 最高级的具体用法 (1) the+最高级(+n.)+比较范围 比较范围通常为in/of/among...介词短语或从句。 He is the tallest boy in our class. 他是我们班最高的男孩。 Safety is the most important of all. 安全是最重要的。 This is the most interesting book that I’ve ever read. 这是我读过的最有趣的书。 (2) one of the +最高级+可数名词复数 此结构表示“...中最...的之一”。 The Amazon River is one of the longest rivers in the world. 亚马逊河是世界上最长的河之一。 Mount Taishan is one of the most popular tourist attractions in China. 泰山是中国最受欢迎的旅游景点之一。 (3) Which/Who...+最高级，A,B or C / 比较范围?
