定义：形容词是用来修饰名词的词，描述名词的性质、外观、特点等。

功能：形容词可以做定语、表语或补助语。

分类：主要分为两类：描绘性形容词和限定性形容词。

● 描绘性形容词主要用来描绘大、小、新旧、颜色、质量等。

● 限定性形容词主要用来限定所修饰词的数量、距离及范围所属等。

1．当形容词修饰单数可数名词时，必须与冠词连用：

a lovely girl, the naughty boy

2．形容词可与系动词连用，做表语，说明主语的性状。常用系动词有：be, become, seem, appear, feel, look, taste, smell, sound, remain, go, turn, keep, stay, etc.

The dish tastes delicious.

The music sounds sweet.新概念英语第二册1

小心陷阱：feel，smell，taste，look，keep有时可以用作实义动词，并可以用副词修饰。

He looked me up and down carefully.

I tasted the soup slowly to see whether it was salty.
