某些形容词与定冠词连用表示一类人作主语时，谓语通常用复数形式。如：

The English like to be with their families.
多个形容词作定语修饰名词的顺序：
冠词序数词基数词性质状态(描述性)形状大小新旧老少颜色国籍材料名词。如：the second five interesting big new red Chinese wall papers.
2、形容词比较等级的形式
(1)规则形式
一般说来，单音节词及少数双音节词在后加-er;--est来构成比较级和最高级;其他双音节词及多音节词在前加more,most.如：
great-greater-greatest
busy-busier-busiest
important-more important-(the)most important
(2)不规则形式

(3)形容词比较等级的用法

②表示两者以上的比较，用"the形容词最高级(名词)of(in)…"如：
He is the cleverest boy in his class.
③表示两者是同等程度，用"as形容词原级as".如：
He is as tall as I.
I have as many books as you.
④越…越…
例如：The more I learn,the happier I am.
⑤You can never be too careful.越小心越好
又如：You can never praise the teacher too highly.
