that位于句首有两种情况:
1.that位于句首引导一个主语从句,
适用于it作形式主语的句型,
如That obama is the president of the USA is all known to us=It is all known to us that obama is the president of the USA. 众所周知,奥巴马是美国总统。
2.用于表示愿望或期盼,常用虚拟语气
That I could fly in the sky. 我要能在天上飞就好了。

that可以单独做主语,后面谓语用单数。
也可以引导主语从句,不做成分。但不可省略。

1 that 用作形容词,修饰主语。
that little son of his 他那个小宝贝儿子
2 that 用作代词。
that 用作指示代词,其指代意义同形容词用法,避免重复,代替前述名词。
That is what he told me.
这个句子中的that作主语
3 that 用作连词,引导名词性从句,状语从句和强调句。
引导主语从句。通常采用it作形式主语的句型。
That the earth goes around the sun is known to everyone.(作主语的同位语)
(It is known to everyone that the earth goes around the sun.)
that 一般在定语从句中作宾语时,起到连接两个句子的作用,无实意时才可省略。
