4、形容词和副词的原级、比较级和最高级的用法:
(1)讲述某人/物自身的情况时,用原级。基本句型是:

如:He is very old now.(他现在很老了)
They ran quite fast.(它们跑得相当快)

☆表示两者之间没有差别时,使用句型:
主语(第一个人物) + 谓语动词 + as + 形容词/副词原级 + as + 第二个人物 +….

(他和他妹妹一样兴奋)

☆表示第一个人比不上第二个人时,使用句型:
主语(第一个人物) + 谓语动词(否定式) + as / so + 形容词/副词原级 + as + 第二个人物+….
如:He is not so / as excited as his younger sister.
(他没他妹妹那么兴奋)
Lily did not ride her bike so / as slowly as an old lady.
(莉莉骑车不像老太太那样慢)
They didn’t pick so / as many apples as the farmers (did). (他们摘的苹果不如农民多)
(2) 讲述两者有差异,第一个人物超过第二个人物时,用比较级。
基本句型:
主语(‘A’)+谓语动词+(much/a little/even/still)+形容词/副词比较级+than+第二个人物(‘B’)+….
如:A modern train is much faster than a car.
现代的火车比轿车快多了

讲述两者有差异,第一个人物不及第二个人物时,用比较级。句型是:

(3)讲述某人/物是一群之中最突出的一个时,用最高级。句型是:

如:The Changjiang River is the longest in China.
(长江是中国最长的河流)
He jumped (the) highest of the three (boys).
(三个男生中他跳得最高)
4、关于比较等级的重要注释:
1、如果动词是及物或不及物动词,则后面用副词;
如果后面是连系动词,则后面用形容词。
如:This car is the fastest of the four.(形容词)
(这辆汽车是四辆之中最快的)
This car runs (the) fastest of the four.(副词)
(这辆汽车是四辆之中跑得最快的)
2、“比较级+and+比较级”表示“越来越……”。

(我们栽的树越多,情况就会越好)
The harder you try,the greater your progress is.
(你越是努力,进步就越大)
4、一般的形容词或副词的比较级前面可以加much/a little/even/still,而表示数量的more之前还可以加some/ any/ no/ one/ two/ many/ several/ a lot等词。
如:It is much colder today than yesterday.
(今天比昨天冷多了)
Would you like some more coffee?
(你还要些咖啡吗?)

5、more than / less than分别可以理解为“多于/少于”,相当于副词,
more than=over; less than=under

(我在纽约生活了四个多月)
6、“one of the +最高级+名词(复数)”整个短语为单数含义,谓语要用单数形式。
如:One of the oldest houses has been burnt in a fire.
(最古老的一幢房子在一场大火中被烧毁了)
7、“Which / Who+动词+形/副,□,□or□?”句型中,如果有两个选项,形/副用比较级,如果有三个选项,形/副用最高级。如:

(林涛和韩梅谁的书最多?)
Which is the heaviest,a pig,a horse or an elephant?
(猪、马、象哪个最重?)
8、上下文中含有both/either/neither/two/twins等表示两个事物的词时,用比较级,而且往往还要加the;含有all/none/no one/ every 等表示三个或三个以上事物时,用最高级。如:
