问题解答：

我来补答

1 that 第一句为主语从句,表述 they have won the game的事实我们已经知道,而 they have won the game表述完整,所以用that引导.
2 what ,that 第二句前边what is known to us是一个主语从句,由于is known to us表述不完整,缺主语,所以用what来引导,使整个句子组成一个主语从句；后边that they have won the game是一个表语从句,由于they have won the game表述完整,所以前方加that
3 as第三句这句是非限制性定语从句,as指代逗号后面整个句子的内容.
4 It ,that 第四局,是it is...that...结构, it作形式主语,替代that引导的从句.
不懂追问,满意望采纳~
