1、中考英语语法讲解资料及练习 第 7 讲 介词 别看介词是一种虚词，它在句中的作用却非常重要。它用来表明名词与句中其他词的关系，不能单独使用。常考点包括一些固定搭配和一些近义词。固定搭配如：on ones way home,help.with,send for,be interested in.,be late for,be angry with,be good at 等。当然这需要你好好记忆了。常用介词解析及用法比较：at,on 和 in：这三个介词在试卷中的出现频率极高。对于它们的的分辨只要记住一句话就可以了。at 表示点，on 表示线，in 表示面。什么意思呢也就是说它们表达的范围逐渐增大
2、。at six oclock,at noon,at the age of sixteen 等用 at 表示时刻或时间的点以及年龄。on 具体到一周中的各天,日期及某特定的一天早上,下午,晚上：on Saturday，on July 1st，on my birthday，on the morning of July 16th，on a spring afternoon。in表达的范围更大一些。与世纪、年代、季节、月份以及早上、上午、晚上等连用。如：in the seventh century，in 1950s,in 2000,in the morning 等。for,since：for 表示多长
3、时间。since 后接时间起点,其终点往往为现在，常与完成时连用。牢牢记住哟。after,in：这两个介词都可以表示时间在以后的意思。其区别是：after 以过去为起点，表示过去一段时间之后，常用于过去时态的句子；in 以现在为起点，表示将来一段时间以后，常用于将来时态的句子。by，with，in：by 表示以.的方式，方法，手段 和 乘某种交通工具；with 指借助于具体的手段或工具；in 表示以.方式，用语言，文字等媒介。for 和 of：试比较：Its impossible for me to watch TV after eleven oclock.Its kind of you to
4、 help me.两句中介词的选择依据其前形容词而定,一般来说,of 之前的形容词往往是用于描写人的品质的好坏，人自身的特点，如聪明与否，细心与粗心等；for 之前的形容词用于描写事物的特点，如可能性，必然性，难易程度等。好，又到了趁热打铁的时间了，来检测一下你的学习成效如何 练习：1.Can you tell the story _Russian A.with B.in C.on D.by 2.Here are some birthday cards _ our teachers,_ our best wishes.A.of,with B.for,with C.of,in D.for,in
