as known to us 还是as it is known to us?

题目

as known to us 还是as it is known to us?
或者还是as is known to us?
as 引导的是什么句子?
还有一个问题.
几月几日用英语怎么讲?就是写出英语来的那种.
听说可以用基数?是不是这样?

答案

1.as is known to us才是对的.
as引导的是一个非限制性定语从句,as代替整个主句,在定语从句中充当主语.
如：As is known to us,the earth goes around the sun.
2.“几月几日”的英语表达为：
“月份 + the + 序数词”,或“月份 + 序数词”再或“月份 + 基数词”
而且其中月份后面一般都有个逗号隔开.
日子用基数词表达也是可以的,但的确少见.
如：四月一日：April,the first / April,first / April,one
