第7讲 介词别看介词是一种虚词，它在句中有哪些用途却尤为重要。它用来表明名词与句中其他词的关系，不可以单独用。常考试知识点包含一些固定搭配和一些同义词。固定搭配如：on o
nes 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。常用介词分析及使用方法比较：at,on和in：这三个介词在试题中的出现频率极高。对于它们的的分辨只须记住一句话就能了。at表示点，on表示线，in表示面。的意思是呢？也就是说它们表达的范围渐渐增大。at six oclock, at noon, at the age of sixteen等用at表示时刻或时间的点与年龄。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、月份与早上、上午、晚上等连用。如：in the seventh century，in 1950s ,in 2000, in the morning等。for,since：for表示多久。since后接时间起点,其终点总是为目前，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未来的意思。其不同是：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 以目前为起点，表示以后一段时间将来，常用于以后时态的句子。by，with，in：by表示以...的方法，办法，方法 和 乘某种交通工具；with指借用于具体的方法或工具；in 表示以......方法，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,通常来讲,of之前的形容词总是是用于描写人的品质的好坏，人自己的特征，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征，如可能性，势必性，难易程度等。好，又到了趁热打铁的时间了，来测试一下你的学习效果怎么样？训练：1.
