语序：陈述语序
在句中充当主语的从句称为主语 从句。英语中主语从句的句型可分 为两大类： 直接将主语从句放在主语位置上； 用it作形式主语，将真正的主语从 句后移，放在其他成分后。
让我们先说说第一类吧！
一、连接词（只起连接作用，在从句中不充当句子成分）
that：无词义。 e.g.: 他赢得比赛一事在我国引起巨大轰动。 That he won the game made a tremendous stir in our country. whether：“是否”。可单独使用，也可与or或or not连用。 e.g.: 我们明天是否能去春游取决于天气。 Whether we can go for a spring outing depends on the weather. 他们是否会来还未告诉我们。 Whether they will come has not been told to us.
四、主语从句与主谓一致
一个从句作主语时，谓语动词通常用单数形式， 特别是用it作形式主语的句型。 e.g.: Whether this kind of chemicals is better has not been tried.
当what引导主从，应遵循意义一致原则，谓语动 词选用相应形式。表语是复数时，谓语动词用复数 形式。 e.g.: What we do willingly is easy. What they were searching for were the missing gems.
