   1. 介词的定义


  介词是一种用来表示词与词, 或者词与句之间的关系的词,在句中不能单独作句成分。介词一定要有宾语,充当宾语的一般有名词、代词或相当于名词的其它词、短语或句子,短语或从句。
  2. 介词的种类
  (1)简单介词,如at, in off, on, by, to, with等。
  (2)合成介词,如into, inside, within, throughout 1等。
  (3)短语介词,如according to, because of, in addition to, in front of, in spite 2 of等。
  (4)二重介词,如from behind, from among, until after, at about等。
  3. 介词的宾语
  (1)名词:Let's go for a walk along the river. 咱们到江边散散步。
  (2)代词:He's standing 3 in front of me. 我站在我前面。
  (3)形容词:Her pronunciation is far from perfect. 她的语音远不是完美的。
  注:有的形容词前可看作是省略了being。
  (4)动名词:He's good at drawing.他善长绘画。
  (5)过去分词:I took it for granted 4 that she was for England.我还以为她是英国的。
  注:过去分词作介词宾语只限于take…for granted 结构和用于regard…as后。
  (6)不定式:I had no choice but to lie down. 除了躺下外我别无选择。
  She did nothing but cry.她只是哭。
  注:介词后通常是不能用不定式作宾语的,只有表示“除……外”的 but, except 等个别介词能接不定式作宾语。前面有行为动词do时,不定式不用 to,否则要带to。
  (7)疑问词+不定式:I don't know how to improve my English.我不知道如何提高我的英语水平。
  (8)副词:I didn't know it until recently. 直到最近我才知道此事。
  (9)数词:He was among the first to arrive. 他是第一批到的。
  (10)介词短语:She won't go home until after the exam. 她要考完试之后再回家。
  (11)从句:Think of what I said. 想想我说的话
  I'm worried about where he is. 我担心他上哪儿去了。
  I have doubts about whether(不用if) he is the best man for the job. 我怀疑他是否做这项工作的最好人选。
  He has no special fault except that he smokes too much.他除了抽烟太多之外,没有什么特别的毛病。
  注:除except that, in that等后可接that从句外,通常只接连接代词、连接副词及whether引导的从句,也不接if引导的从句。
  4. 介词短语的作用
  介词和它的宾语构成介词词组,其用法如下:
  (1)作定语:The girl in red is my sister. 穿红衣的那个女孩是我妹妹。
  注:介词短语作定语总是放在它所修饰的名词后面。
  (2)作状语:Can you say it in English? 这个你会用英语说吗?
  (3)作表语:He's in the office. 他在办公室。
  (4)作补语:I always find her at her studies. 我经常发现她在学习。
  (5)作介词宾语:I saw her from across the street. 我从街对面望见了她。
