中考英语语法讲解资料及练习：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。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 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?
