高一英语主语从句课件人教版新课标必修1 课件.ppt

1．引导主语从句的连接词有三类：
(1)连词that、whether：
Whetherwegobytrainorbyboatmakesnodifference.
Whetherhe’llcomehereisn’tclear.
Thatpricewillgoupiscertain.3)连接副词where,when,how,why等。
Howthishappenedisnotcleartoanyone.主语从句后置!
为了避免主语冗长,句子头重脚轻,经常用it作形式主语,主语从句放在后面作真正的主语.
例:
Thatweshallbelateiscertain.
--It’scertainthatweshallbelate.
