1、以上六个句型中,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……”。如：The weather is getting warmer and warmer.(天越来越温暖了)

3、“the+比较级…,the+比较级…”表示“越…就越…”。如：The more trees we plant,the better it will be.(我们栽的树越多,情况就会越好)/ The harderyou 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?)/He did not eat any more.(他没有再吃)

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.如：I lived in New York for more thanfour months.(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：Who has more books, Lin Tao or Han Mei?(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： --Do you like the smaller one?—Neither.(小一点的那个你喜欢吗?一个都不喜欢)/ --Which do you like best? –All of them!(你最喜欢哪个?全部。)
