中考语法复习:介词的讲解及提升练习
一、定义:
介词:是一种用来表示词与词、词与句之间的关系的词,在句中不能单独作句子成分。
二、介词短语的句法作用
1、介词短语相当于一个形容词或副词,可用作状语、定语和表语。
如:The man came .(状)
The woman is from the countryside.(定)
The teacher is now with the pupils.(表)(老师现在和学生在一起)
2、介词短语在句子中的位置:
介词短语做状语时,如果表示时间/地点,可以放在句首或句尾。
如果表示方向/方式/伴随/涉及/原因/目的/比较,一般放在句尾;
介词短语作表语时放在连系动词之后;介词短语作定语时,只能放在被修饰的名词之后。
如:He wanted to find a good job in Shanghai the next year.(状语)
They searched the room for the thief.
The letters are for you.(表语)
Have you seen a cat with a black head and four white legs?(定语)

but 常用在 every, any, no 和由这些词构成的复合词出现的句子中,并放在 everything,
anywhere, nobody 等以及 all, who 之后。
e.g. Nobody was late but you.
we have no choice but to wait for his reply.
* 注意:
当but前面有实义动词do或do的其他变化形式时,只加动词原形.。
e.g. I did nothing but wait there for two hours.
③except 其后接的词同句子的主语是同类的,指在同类的众多个体中除去一个个体。侧
重指后面除去的部分。
e.g. All the students go to the zoo except Jim.
补充:
* except for 其后所接的词同句子的主语不是同类的,指从整体中除去一个细节,一个方
面。即“美中不足”
