初中英语语法总结之介词解析
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。下面是小编给大家带来的初中英语语法总结之介词解析，希望能够帮助到大家!
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 o'clock, 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 1950's ,in 2000, in the morning等。
学习啦在线学习网 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：It's impossible for me to watch TV after eleven o'clock. It's 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?
