U3 Our digital lives 语法专项 章 语法概览 ★形容词比较级与最高级 章 语法精讲精练一 形容词的比较级和最高级是中考的核心重难点，主要用于对事物进行比较。 1.规则变化与不规则变化（变形是基础） 形容词变为比较级和最高级，需遵循以下规则： 构成方法 原级 比较级 最高级 单音节词 ①一般直接 tall taller tallest 加-er,-est ②以e结 尾，加工， nice nicer nicest st ③辅音字母 +y结尾，变 y为i,加 happy happier happiest er,-est ④重读闭音 big bigger biggest 节，双写末 尾辅音，加 -er,-est 多音节词/部 分双音节词 在词前加 beautiful more beautiful most beautiful more,most important more important most important ☆特殊变形 表（务必熟 记) good/well better best bad badly ill worse worst many much more most little less least far farther/further farthest/furthest 考点提示： *farther/farthest指具体的距离远近；further/fuurthest指抽象的程度深浅。 *fiiendly等以-y结尾的形容词，变形时用moIe和most。例如：fiiendly→more fiiendly →most friendlyo 2.比较级的核心用法（两者比较) 用法结构 例句 考点解析 ①A+bet This book is more interesting than that 比较级前不加the。√than是关键 比较级+ one.(这本书比那本有趣。) 词，引出比较对象。 than+B ②比较级 The weather is getting hotter and hotter. 表示“越来越…”，多音节词用more +and+比 (天气越来越热了。) and more+原级。 较级 ③The+比 较级，he+ The more you read,the smarter you will 表示“越…，就越…”，是一个固 be.(你读得越多，就会越聪明。) 定句型，中考高频。 比较级 3.最高级的核心用法（三者及以上比较) 用法结构 例句 考点解析 ①A+be+ He is the tallest student in our class.(他是 √最高级前必须加he。√比较范围： the+最高级 我们班最高的学生。) im+地点/组织：of+群体/三者以上。 +比较范围 ②one of the Shanghai is one of the most beautiful cities 表示“最…之一”，其后名词要用复 +最高级+ in China.(上海是中国最美丽的城市之 数形式。 复数名词 一。) ③he+序数 The Yellow River is the second longest 表示“第几…的”，常用于描述排 词+最高 river in China.(黄河是中国第二长的河 名。 级 流。) 4.原级比较结构（同级比较，中考易混点） 用法结构 例句 考点解析 肯定：as+ This room is as big as that one.(这个房间 表示“和…一样”。 原级+as 和那个一样大。) 否定：not This dress is not as/so beautiful as that one. 表示“不如…”。否定句中$0可替 as/s0+原级 (这件裙子不如那件漂亮。) 换aso +as 5.★易混考点辨析 形容词VS.副词（词性判断） 形容词修饰名词/系动词后作表语：副词修饰实义动词/形容词/副词。 比较：He runs fast.(副词，修饰动词ns)/He is a fast1nner.(形容词，修饰名词ne) 比较级前的修饰语（表示程度） 常用：much,alot,a little,even,far,any,no等。 例：She is much taller than me.(她比我高得多。)/This problem is a little more difficult..(这个 问题稍微难一点。) he+比较级”的特殊情况 当比较级特指“两者中较…的一个”时，需要加he 例：Tom is the taller of the two boys.(汤姆是两个男孩中较高的那个。) 二、专项训练（中考/名校月考难度） （一）单项选择 1.Of the two pairs of shoes,I chose the one because it fit me better.
