位置与功能
高考重点要求
1．掌握形容词、副词比较级、最高级的常用句型及用法
2．掌握形容词、副词的原级、比较级和最高级修饰语及倍数的比较表达。
3．注意多外形容词修饰同一名词的前后顺序。
4．分清常用同义与近义形容词在表达中的语义差别。
此项语法内容从1991年到达2001年间共出现45次（包括上海题），可见其重要。
形容词作用与位置
1．定语。
在名词前做定语，为最常见用法。请注意多个形容词（含其它起形容词作用的词）做前置定语的顺序。
"县官行令杀国才。"这一句就概述了形容词顺序问题。即：
限（冠词[物主代词、指示代词]数词等）观 （描绘） 形（大小、形状等） 龄 （年龄、新旧等）色（色彩）国（国籍、出处等）材（材料、功用等）
an interesting English film a heavy black Chinese silk umbrella
做后置定语。修饰由不定代词no ,any, some ，every和one,thing等构成的复合词或形容词短语。
2．表语。一定要注意系动词的出现情况。这是一个高考热点问题。
常见系动词有：be
变化系词： become, get ,turn, grow, go
保持系词： keep ,remain, stay
感观系词： look, smell , taste, feel, sound,appear , seem ,prove etc.
3.形容词作状语，表状况、原因、结果等。这也是应注意的一点。
He went to bed , cold and hungry.
4.做宾补。
N：①某些以a 开始的形容词只做表语，不做定语。
afraid, alike, alone, asleep ,awake，alive
②某些表身体健康状况的形容词只能做表语,不做定语
well, ill faint
③某些以-ly 结尾的词是形容词而不是副词。
friendly, lively, lovely, lonely, likely, deadly, orderly 等。
④复合形容词的形式问题。
an 800-meter-wide river an English-speaking country a middle-aged man
副词
位置
1）时间副词和地点副词一般放于句尾。如同时出现，则地点副词在前。
They went boating in Zhongshan Park yesterday.
2)表频率的时间副词是高考的热点
always, seldom, often, never, rarely, usually 等，通常放于行为动词之前，be词、情态动词和助动词之 后。
He is always telling lies,so I will never believe him.
3)程度副词一般放在被修饰词之前（但 enough除外）
He is very young ,so he is not old enough to go to school.
N:有些副词有两种形式，一个与形容词同形，一个以ly 结尾，但它们的含义是不同的。
closely-close nearly-near freely-free deeply-deep highly-high widely-wide 等。
以ly 结尾的词表较为抽象的含义，而与形容词同形的副词则表较为具体的概念。
He is highly praised for what he has done. (高度地)
He can see a bird is flying high in the sky.（飞得高，具有可见性）
