全优课堂2017版高考英语一轮复习第二部分核心语法项项破专题6并列句和状语从句课件

1、专题六并列句和状语从句专题六并列句和状语从句 一、并列连词yet，but，when，while，for，so的用法连词用法yet表示转折， 此时注意 yet位置且前面必须加逗号。but连接两个并列成分或两个并列分句，意为“但是，然而”。连词用法when作并列连词时，意义为“这时，那时”，相当于and at this/that time。常用于下列句式：sb.was doing sth.when sb.was about to/going to do sth.whensb.was on the point of doing sth.whensb.had just done sth.whenwhi

2、le作并列连词时，意为“而，却”，表示对比。连词用法for表示因果关系，引导并列分句，对前面分句加以解释或补充说明，且只能后置，常用逗号与前面的句子隔开。so表示因果关系，意为“因此”。特别提醒although/though不能与but连用，但可以和yet或still连用。 选用上表中适当的连词填空 1.
