PETS-3常见语法知识点（形容词用法）

形容词的用法、比较等级形式及其示例：

1、形容词的用法

形容词是用来修饰、描绘名词的，通常在句中作定语、表语或宾补，有时还可作状语。如：

He is honest and hardworking.

I found the book interesting.

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 rich and the poor live in different parts of the city.

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

一般说来，单音节词及少数双音节词在后加-er;--est来构成比较级和较高级;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
