语法填空中怎样区分并列句和复合句?
比如说:worse perhaps was the idea of having to teach them on Saturday afternoon___most of my friends would be enjoying themselves.怎样判断这个空是连词还是引导词?

1.利用文章中心主题句解题方法------利用段首句或首段最大限度地获取信息.
为给学生理解文章奠定基础,使学生更易于理解文章内容,出题者在设计完形填空试题时,总是保留一个完整的、或是大半个完整的表达主旨的句子.大家知道,文章的开头很重要,往往开宗明义点出文章主题.因此,整篇文章的提示句往往在开头.考生应充分利用段首句提供的信息,去挖掘文章的思路,寻找文章的脉络与线索.
2.分析认识文章结构,理解领会文章各部分、各层次之间的逻辑关系.
只有明白文章结构,了解各段落之间的关系,才能加深对文章的理解.明白了各部分是如何为表现主题思想服务的,也就更容易把握带空的句子所需要的是什么内容,因此就更容易选准答案了.这要求考生具有扎实的英语词组、短语、习惯用法等英语搭配的知识,这对于理解文章的逻辑关系特别有利.文章的逻辑关系不外乎列举、原因、结果、让步、对照、补充、目的、条件等关系.
表示列举的连词：first,second,third…;firstly,secondly,thirdly…; first,next,then…; in the first place,in the second place…; for one thing,for another thing…;to begin with,to conclude…

表示对照的连词：on the contrary,in contrast,by contrast,in comparison,by comparison,conversely
表示补充的连词：also,further,furthermore,likewise,similarly,moreover,in addition,what’s more,too,either,neither,not…but…,not only…but also…
表示时间顺序的连词：when,while,as,after,before,since,until,as soon as,once
