外研版7下第五单元语法专练 形容词比较级和最高级 第一部分:核心知识点梳理 一、什么是形容词的比较级和最高级? 形容词用于描述人或事物的特征。当我们需要对事物进行比较时,就要用到形容词的比较级和最高级。 原级:描述事物本身的状态。例如:tall(高的)、beautiful(美丽的) 比较级:两者之间的比较,表示"更……"。例如:taller(更高的)、more beautiful(更美丽的) 最高级:三者或三者以上的比较,表示"最……"。例如:tallest(最高的)、most beautiful(最美丽的) 二、形容词比较级和最高级的构成规则 1. 规则变化 单音节词:在词尾加er / est tall taller tallest short shorter shortest fast faster fastest 单音节词以e结尾:只加r / st nice nicer nicest large larger largest late later latest 重读闭音节结尾,且末尾只有一个辅音字母:双写该辅音字母,再加er / est big bigger biggest hot hotter hottest thin thinner thinnest fat fatter fattest 以"辅音字母+y"结尾的双音节词:变y为i,再加er / est happy happier happiest easy easier easiest busy busier busiest funny funnier funniest 多音节词(三个或以上音节):在词前加more / most beautiful more beautiful most beautiful interesting more interesting most interesting expensive more expensive most expensive popular more popular most popular 部分双音节词:既可以用er/est,也可以用more/most clever cleverer / more clever cleverest / most clever common commoner / more common commonest / most common polite politer / more polite politest / most polite quiet quieter / more quiet quietest / most quiet 2. 不规则变化 有一些形容词的比较级和最高级形式是完全不规则的,需要单独记忆: | 原级 | 比较级 | 最高级 | | good / well | better | best | | bad / ill | worse | worst | | many / much | more | most | | little | less | least | | far | farther / further | farthest / furthest | | old | older / elder | oldest / eldest | 注意区分: farther / farthest 指具体的距离"更远" further / furthest 指抽象的程度"更进一步" older / oldest 指年龄大小 elder / eldest 通常指兄弟姐妹间的长幼关系 三、比较级的基本句型 1. 两者相等:as + 原级 + as 表示"和……一样……" Tom is as tall as Mike. This book is as interesting as that one. She is as beautiful as her mother. 2. 两者不相等:not as/so + 原级 + as 表示"不如……" Tom is not as tall as Mike. This book is not so interesting as that one. He is not as smart as his brother. 3. 超过比较:比较级 + than 表示"比……更……" Tom is taller than Mike. This book is more interesting than that one. She works harder than before. 4. 递减比较:less + 原级 + than 表示"不如……"(与not as...as类似,但更正式) This problem is less difficult than that one. He is less careful than his sister. 5. 程度递增:比较级 + and + 比较级 表示"越来越……" It's getting colder and colder. The story becomes more and more interesting. Our city is becoming more and more beautiful. 6. 平行变化:the + 比较级,the + 比较级 表示"越……,就越……" The harder you work, the greater progress you'll make. The more you read, the more you learn. The sooner, the better. 四、最高级的基本句型 1. 三者以上比较:the + 最高级 + 比较范围 表示"在……中最……" Tom is the tallest student in our class. This is the most interesting book I've ever read. Mount Qomolangma is the highest mountain in the world. 2. one of the + 最高级 + 复数名词 表示"最……的之一" He is one of the best students in our school. This is one of the most famous universities in China. She is one of the most popular teachers. 3. 最高级前有物主代词时,不加the Monday is my busiest day. This is my best friend. Summer is our hottest season. 五、常见易错点 1. 比较的对象要对等 误:My room is bigger than you. 正:My room is bigger than yours. / My room is bigger than your room. 2. 比较级前可用修饰语 常用修饰语:much, a lot, far, a little, a bit, even, still much taller(高得多) a little cheaper(便宜一点) far more beautiful(美丽得多) even worse(甚至更糟) 3. 不能同时使用两种比较形式 误:She is more smarter than me. 正:She is smarter than me. / She is much smarter than me. 4. 形容词最高级前通常要加the 但副词最高级前的the可以省略 Who runs (the) fastest in your class? 5. 比较范围的区别 in + 集体名词/地点(in our class, in the world) of + 个体名词复数(of all the students, of the three) 第二部分:专项练习题 一、写出下列形容词的比较级和最高级(共15题) 1. tall _ _ 2. nice _ _ 3. big _ _ 4. happy _ _ 5. beautiful _ _ 6. good _ _ 7. bad _ _ 8. many _ _ 9. little _ _ 10. far _ _ 11. thin _ _ 12. easy _ _ 13. interesting _ _ 14. hot _ _ 15. busy _ _ 二、单项选择(共10题) 16.
