初中英语专题复习——介词一、介词概念介词是一种虚词，它在句中的作用非常重要。

它用来表明名词与句中其他词的关系，但是介词不能单独使用。

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 angry with，be good at等。

for表示多长时间。

since后接时间起点，其终点往往为现在，常与：这两个介词都可以表示时间"在以后"的意思。

其区别是：after 以；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表示"以…的方式，方法，手段" 和"乘某种交通工具"；with"；in 表示"以……方式，用语言，文字等媒介"。

It's impossible for me to watch TV after eleven o'clock.It's kind of you to help me.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。
