英语中必须掌握的连词

　　汉语和英语两种语言之间最基本的区别在于句法方面。英语重形合 （hypotaxis），句中各意群、成分都用适当的连接词 （connective）、介词 （preposition）、非限定性动词短语 （phrase）或从句 （clause）等来表达其相互关系，因而结构严谨但缺乏弹性；而汉语句法则重意合（parataxis），句中各意群、成分通过内在的联系贯穿在一起，不一定或很少用连接词、介词，也没有非限定性动词短语或从句，因此结构松散，但富于弹性，从句子整体来看，意义清楚，不会产生误解。

　　今天，我们就来分门别类地介绍一些英语词类中最容易掌握，而且必须掌握的连接词。
