2、末尾只有一个辅音字母，则双写这个辅音字母后再加词尾-er和-est构成比较级和最高级。如： longlongerlongest largelargerlargest busybusierbusiest bigbiggerbiggest,一、形容词与副词比较等级的构成方法,Page 4,2. 多音节和部分双音节形容词在其前加more和most构成比较级和最高级。如： usefulmore usefulmost useful difficultmore difficultmost difficult 常见的不规则形容词与副词的比较等级变化： goodbetterbest； wellbetterbe
3、st； badworseworst； badlyworseworst； illworseworst； muchmoremost； manymoremost； littlelessleast； farfarther / furtherfarthest / furthest；等。 注：less和least也用来构成比较级或最高级，表示“较不”和“最不”：carefulless carefulleast careful。,一、形容词与副词比较等级的构成方法,Page 5,二、比较等级的常见句型,(1)两者相比，甲=乙，用“as +形容词或副词原级+ as”。如： He got up as early
4、 as I did.他和我起得一样早。 注：当asas中间有名词时，名词要放在形容词之后。如： I can carry as much paper as you can.你能搬多少纸，我也能。 (2)两者相比，甲乙，用“not as/so+形容词或副词原级+as”。 Corn doesnt need as/so much water as rice.玉米不需要稻谷那么多水。,Page 6,二、比较等级的常见句型,(3)两者相比，甲乙，用“比较级形容词或副词+ than”。如：You are taller than I. 你比我高。He reads more careful than I.他比我
5、看书更认真。 (4)多者比较，用“the+最高级+比较范围”。如：Tom is the tallest in his class.汤姆是他班里个子最高。,Page 7,三、比较等级的特殊句型,(1) less/least +原级：表示降级的比较级或最高级。如： I am even less lucky. This is the least useful of the four books. (2) the+比较级, the+比较级：表示后者随着前者的变化而变化，意为“越就越”，前者相当于一个条件句，因此，要用一般现在时代替一般将来时。如： The harder you work, the be
6、tter result youll get. (3) the+比较级(+of the two)：表示“两者中较的那个人或物”。如： Tom is the taller of the two brothers.,Page 8,三、比较等级的特殊句型,(4) 比较级+and+比较级：表示“越来越”， 单音节形容词或副词用“-er+and +-er”，warmer and warmer 多音节形容词或副词用“more and more”more and more beautiful (5) 比较级+than any other+单数名词：表示最高级意义。 Mike is more intellige
7、nt than any other student in his class.(=Mike is the most intelligent in his class.)

(8) more+形容词或副词+than：表示对同一人或物在不同方面进行取舍，意为“与其说倒不如”，不论形容词或副词的长短
8、，一律用morethan。如：He is more hungry than tired. (9) no +比较级+ than：表示对两者的否定，意为“和一样不”，与neithernor或“as+相反意义的形容词或副词+as”相当。如 Tom is no taller than Mike. =Neither Tom nor Mike is tall. =Tom is as short as Mike.汤姆和迈克都不高(或一样矮)。 比较：“not+比较级前+than”表示前者不如后者。Tom is not taller than Mike.汤姆不比迈克高。,Page 10,四、比较级和最高级的常

11、ycle in the shop.,Page 12,五、形容词与副词的比较等级用法注意,1. 比较级的基本用法 形容词和副词有三个等级，即原级、比较级和最高级。比较级主要用于两者比较，最高级主要用于多者比较。 2. 不能使用双重比较等级 构成比较级时不能既加词尾-er，又在其前加more；构成最高级时不能既在词尾加-est，又在其前加most，如不能说more better, most earliest 等。不过“比较级+and+比较级”这样的形式却完全可用。如： I am getting fatter and fatter.
