同学您好：由that引导的主语从句
1）这是用的最多的一种主语从句，但把这种主语从句放在句首是很少的，只是为了强调或谓语较长时才这样安排。例如：
That prices willgo up is certain.
That she isstill alive is a consolation. (安慰)
2）绝大部分主语从句都借助先行主语放到句子后部去。
a.It +be + 形容词+that从句：
Itis natural that they should have different views.
Itwas quite obvious that she didn’t want to come.
b.It +be + 名词 +that 从句：
It’sa shame that you’re sick.
It’s a pity that he can’t swim.
c.It + 动词（+ 宾语或状语）+ that 从句：
Ithappened that she wasn’t in that day.
Itseems that you’re right.
d.It + 动词的被动语态 + that 从句：
It’ssaid that there has been an earthquake in India.
It’sreported that the enemy troops have crossed the border.
