1. 限定用法：形容詞緊靠著〔代）名詞，直接修飾該〔代）名詞。

　　(1) 前位修飾：

　　(A) 字尾為en或表比較的形容詞，大多只能作限定用法，放在名詞的前面。

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

　　(B) 下列這些形容詞只有限定用法，沒有敘述用法。

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

　　(C) 形容詞前有so; no; too; how等字時，不定冠詞應(yīng)放在形容詞之后。

　　He could not do it in so short a time.

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

　　(2) 后位修飾：

　　(A) 名詞之后的數(shù)詞＋名詞＋old; long; high; wide; deep; etc.

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

　　(B) 為加強語氣或音調(diào)美，而將限定形容詞放在后面。

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

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

　　I'll tell you something very important.

　　That's nothing new.

　　D) 由形容詞子句省略主詞和動詞而不的過去（或現(xiàn)在）分詞或形容詞片語。

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

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

　　2. 敘述用法：形容詞作補語，間接地修飾〔代）名詞。

　　He was awake all the night. 〔主詞補語）

　　The noise kept me awake. 〔受詞補語）

　　注：可作限定用法和敘述用法的形容詞。

　　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. 作補語的形容詞：

　　(1) be＋形容詞＋介系詞：由此結(jié)合而成的片語，有些等于及物動詞。

　　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) 某些已轉(zhuǎn)化為形容詞的過去分詞，其后通常接at; about; with; in; of等介詞。

　　John is interested in English grammar.

　　He was surprised at her behaviour.

　　(3) be＋形容詞＋介系詞：可接〔代）名詞，動名詞，或名詞子句，但名詞子句若是that子句須省略介詞，因that子句不可直接作介詞的受詞。

　　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 ＋形容詞＋that子句

　　It is true that she never came.

　　此類形容詞有：certain; likely; obvious; plain; possible; true; etc.

　　(A) that子句中的假設(shè)法。

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

　　(B) 人稱形容詞亦可接其他連接詞引導(dǎo)的子句。

　　I'm not sure why he came.

　　I'm not clear where she went.

　　4. 有關(guān)worth; worth while; worthy的句型 如下:

　　(A) 主詞(含it) + be worth + (動)名詞

　　(B) It(虛主詞) + be worth while + 不定詞或動名詞

　　(C) 主詞 + be worthy + of + (動)名詞

　　主詞 + be worthy + 不定詞

　　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只能作介詞不能作連接詞; as則兩者都可。

　　I hoped to succeed as you have (succeeded).

　　I hoped to succeed like you.

　　I hope to succeed *like you have. (like作連詞是非正式的用法)
