本文熟识高中英语语法中的句法：定语的界说、类别、位置与词序。
一、定语的界说
界说： 定语是用来修饰、边界、讲明名词（代词）的品性与特征的词或词组。
英文界说：Attributives are words or phrases used to modify, limit and explain the quality and characteristics of nouns (pronouns).
二、作定语的词类
1. 形色词：She is a natural musician.
2. 名词：Well water is fit to drink.
3. 代词：Your hair needs cutting.
4. 数词：There is only one way to do it.
{jz:field.toptypename/}5. 副词：He has asked a day off.
6. 不定式：She has a wish to travel around the world.
7. 动名词：You had better improve your learning method.
8. 分词：The developed countries ought to help the developing countries.
9. 介词短语：The wild look in his eyes spoke his anger.
10. 从句（定语从句）：The car that has parked outside is mine.
三、定语的位置
1. 前置位：单词作定语时，常置于其所修饰的名词之前。
2. 后置位：短语和从句用作定语时，一般齐置于其所修饰的名词之后。
四、后置定语的几种情形
1. 以字母a-来源的表语形色词作定语（alone, afraid, alike, aware, awake） I am the most happy man alive.
2. 以-able或-ible收尾的形色词作定语（后置的还有present, proper） Put your idea into the simplest language possible.
3. 形色词等用作复合代词的定语时 I’d like to have something interesting to read.
4. 形色词成对时 It was April, balmy and warm.
5. 用作定语的单词自身具有修饰语时 Never have I seen a face so happy and sweet.
6. 不定式用作定语时 I’ll have a lot of homework to do today.
7. 分词短语用作定语时 It was an exciting story unheard of.
8 定语从句用作定语时（定语从句专题另讲） His father who is fifty years old works in a factory.
五、多个前置定语的陈列端正
1. 通用秩序：边界词—形色词—分词—动名词—名词性定语+中心名词。
例：the newly-built shopping mall
2. 形色词陈列词序：限（边界词）—不雅（外不雅）—形（形态大小、高矮等）—龄（年级）—颜（情愫）—国（国籍）—材（材料）—用（用途）+名词短语。
例：a famous American university / an interesting little red French oil painting.
