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 one's way home, help...with, send for, be interested in..., be late for, be angrywith, 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。
for和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和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和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。
