小学生英语知识点:形容词(2)

2016-11-27 10:32:44  来源:网络整理


  

  形容词(2)


  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)
