1. 多个形容词作前置定语的排列顺序:
前位限定词(all / both /such / what …)(即特定限定词)+ 中位限定词(冠词/指示代词/物主代词…)+ 数词(先序数词后基数词)+ 形容词(描绘性+大小、长短、高低+形状+年龄、新旧+颜色+国籍、地区、出处+物质、材料+用途、类别)+名词+名词。如:

形容词的比较级和最高级
英语中大多数形容词都可用于比较。当它们表示两个或两个以上的人或事物的某些性质特征之间的程度上“相等”,“超过”与“低于”或“最……”等时,要用比较等级。它们有三种形式:原级(the positive
degree),比较级(the comparative degree)和最高级(the superlative degree)。
1. 形容词的比较级和最高级的构成形式分为规则和不规则两种。
规则形容词的比较级和最高级的构成形式是:
在通常情况下,单音节和少数双音节词,比较级加-er,最高级加-est。如: small(小的) smaller(较小的) smallest(最小的)
以e结尾的词,比较级加-r,最高级加-st。如:nice(好的) nicer(较好的) nicest(最好的)
以一个元音字母加一个辅音字母结尾的重读闭音节,双写词尾的辅音字母,再比较级加-er,最高级加-est。如: thin(瘦的) thinner(较瘦的) thinnest(最瘦的)
以辅音字母加y结尾,变y为i,再比较级加-er,最高级加-est。如:
happy(高兴的) happier(比较高兴的) happiest(最高兴的)
在通常情况下,双音节词和多音节词,比较级在形容词前加more(更……)或less(更不……),最高级在形容词前加most(最……)或 least(最不……)。如: foolish(愚蠢的) more foolish(较愚蠢的) most foolish(最愚蠢的) necessary(必要的) more necessary(更有必要的) most necessary(最有必要的)
注: a. 一些双音节形容词的比较等级既可采用-er和-est形式,也可采用加more和most的形式。如:
cleverer cleverest
clever(聪明的){
more lever most clever
simpler simplest
simple(简单的){
more simple most simple
b. 以 –y, -ow, -le, -er, -ure等结尾的形容词多采用-er和-est形式。如:
healthy(健康的) healthier healthiest able(有能力的) abler ablest

c. fit, glad, ready, right, pleased, tired, wrong等形容词通常采用加more和most的形式。如:
fit(适合的) more fit most fit
d. 复合形容词的比较等级多采用加more或most的形式。如:
good-looking(样子好看的) more good-looking most good-looking
不规则形容词的比较级和最高级的构成形式:

better
best
many, much
more
most
bad, ill
worse
worst
little
less
least
far
farther, further
farthest, furthest
old
older, elder
oldest, eldest
注: a. farther, farthest主要指距离的更远和最远; further既可指距离的更远,也可指程度上“更进一步,更深入的”。如:

2. 形容词的比较等级的用法
