单元语法点讲解
介 词 介词是一种表示它后面的名词和句子其它词之间的关系的词。介词分为简单介词和短语介词。
简单介词由一个单词构成, 如：at, on, in, after。短语介词是由两个或两个以上单词构成, 如: in front of, out of。
介词和它后面的词一起构成介词短语。如： in the room, on the wall。
下面是常用简单介词用法示意图
连 词 用来连接词与词、短语与短语, 句子与句子的词，叫做连词。英语里连词要比在汉语里用的多, 汉语里往往不需用连词, 但在英语中要用. 如汉语说 “我叔叔生活工作在昆明”译成英语是:. My uncle lives and works in Kunming.
连词本身的形式来看, 可分为: 简单连词和短语连词。简单连词如： and(和, 并且), for(因为), but(但是), after(在…后)等。短语连词如： as if(犹如), as soon as(一……就……)等。
