独立主格题目_____ Sunday,the library doesn't open.A.There being B.It being
_____ Sunday,the library doesn't open.
A.There being B.It being
我想知道理由
答
b
独立主格从句的特点，主从句的主语不同
本句是一个表示原因的独立主格从句。（由于）今天是星期天，图书馆不开门。
今天是星期天 ，用简单现在时表示就是It is Sunday.在独立主格从句中 ，IS 变为 ing 形式。
答
答案是B
独立主格结构，在这里做原因状语。
等于As it is Sunday, the library doesn't open.
答
B
根据语境,考查独立主格结构作原因状语,相当于：As/Because it was Sunday,
it being为it is 的变形.
there being 为there be的变形,表示（某地/某时）有.,明显不符合语境.
