1. 限定用法：形容词紧靠着〔代）名词，直接修饰该〔代）名词。

　　(1) 前位修饰：

　　(A) 字尾为en或表比较的形容词，大多只能作限定用法，放在名词的前面。

　　a wooden leg； earthen ware； his elder sister； the upper room， etc.

　　(B) 下列这些形容词只有限定用法，没有叙述用法。

　　upper； former； latter； outer； inner； utmost； mere； only； utter； main； certain； very； live； spare；

　　(C) 形容词前有so； no； too； how等字时，不定冠词应放在形容词之后。

　　He could not do it in so short a time.

　　He is no less remarkable a man than his elder brother (is).

　　(2) 后位修饰：

　　(A) 名词之后的数词＋名词＋old； long； high； wide； deep； etc.

　　a man eighty-five years old； a river two hundred miles long；

　　(B) 为加强语气或音调美，而将限定形容词放在后面。

　　He had a face thin and worn， but eager and resolute.

　　(C) something； anything； everyone； anybody... ＋ 形容词。

　　I‘ll tell you something very important.

　　That’s nothing new.

　　D) 由形容词子句省略主词和动词而不的过去（或现在）分词或形容词片语。

　　I have answered all the letters (which were) received (by me).

　　Alfred was a king anxious for his people‘s welfare.

　　2. 叙述用法：形容词作补语，间接地修饰〔代）名词。

　　He was awake all the night. 〔主词补语）

　　The noise kept me awake. 〔受词补语）

　　注：可作限定用法和叙述用法的形容词。

　　I have many trustworthy friends. 和 All of my friends are trustworthy.

　　It was a hot and sultry day. 和 The weather became hot and sultry.

　　3. 作补语的形容词：

　　(1) be＋形容词＋介系词：由此结合而成的片语，有些等于及物动词。

　　I am fond of skiing. = I like skiing.

　　He is afraid of it. = He fears it.

　　注：其他如：be capable of； be concerned with； be (un)familiar with (to)； be late for； be subject to； be worthy of； etc.

　　(2) 某些已转化为形容词的过去分词，其后通常接at； about； with； in； of等介词。

　　John is interested in English grammar.

　　He was surprised at her behaviour.

　　(3) be＋形容词＋介系词：可接〔代）名词，动名词，或名词子句，但名词子句若是that子句须省略介词，因that子句不可直接作介词的受词。

　　She was not aware of the facts.

　　She was not aware (of) how much her husband earned.

　　She was not aware that there is danger.

　　(4) It+ be ＋形容词＋that子句

　　It is true that she never came.

　　此类形容词有：certain； likely； obvious； plain； possible； true； etc.

　　(A) that子句中的假设法。

　　It is appropriate that he (should) get the post. （should可省略〕

　　(B) 人称形容词亦可接其他连接词引导的子句。

　　I’m not sure why he came.

　　I‘m not clear where she went.

　　4. 有关worth； worth while； worthy的句型 如下：

　　(A) 主词(含it) + be worth + (动)名词

　　(B) It(虚主词) + be worth while + 不定词或动名词

　　(C) 主词 + be worthy + of + (动)名词

　　主词 + be worthy + 不定词

　　his book is worth reading. (= It is worth while to read this book. = This book is worthy of reading. = This book is worthy to be read.)

　　5. like和as： like只能作介词不能作连接词； as则两者都可。

　　I hoped to succeed as you have (succeeded).

　　I hoped to succeed like you.

　　I hope to succeed *like you have. (like作连词是非正式的用法)
