Question

So many students _for the traffic jam , the exam had to be put off.

A.were late
B.had been late
C.being late
D.been late(选什么，为什么？）

Answer 1

选C，非谓语
主句the exam had to be put off的主谓是完整 的
So many students being late for the traffic jam 用ing表示原因的状语从句，由于主从句的主语不一致，所以从句自己跟上了主语So many students ，如果一致的情况下，从句的主语可以省略！

Answer 2

being
这应该是一句话,之间没有连词,所以只能有一个谓语动词,只有选C

Answer 3

So many students __________ for the traffic jam, the exam had to be put off. A. were late B. been late C. has been late D. being late With his money __________, he couldn’t go home.

Answer 4

选C

本人今年高考英语高分 听我的没错 哈哈~不要拍我。。

楼上说的半对。这个句式叫做独立主格，真正的谓语在后半句。正是因为前后两句主语不同，所以前一句加上了主语，但没有谓语，叫做独立主格。这不能说是从句，因为连引导词都木有。

再给个例句哈
The weather being fine,we felt happy
