so many students ( ) because of the bad weather,the exam had to be put off
A were late B been late C has been late D being late

D
逗号后面没有并列连词and,说明前后两句话不是并列关系.the exam had to be put off是一个句子,有主语（the exam)有谓语（had to be put off),说明这是一个句子.那么逗号前面就不是一个句子,而是一个短语.
A、C两项只能作谓语动词.如果一个语法成分有谓语动词,那么它就一定是句子.因此排除A、C.
students与being late是主谓关系,因此要用现在分词的形式表示主动.so many students being late because of the bad weather是现在分词短语作原因状语.
不明白的再问哟!请记得采纳,多谢!
再问： being late 求解释这是什么非谓语,, doing 表主动 done表被动这个being late算什么。。
再答： being late算主动。being是系动词的现在分词形式，late是它带的表语。系动词属于不及物动词，它没有被动。其实现在分词啊，过去时分词啊，不定式啊，这三个都是非谓语动词。非谓语动词就是不能充当谓语的动词。我们知道，本题的主句在逗号后面。其主语是the exam，谓语是had to be put off。一个句子只能有一个谓语，因此逗号前面只能用非谓语动词的形式。如果逗号后面有一个and，那么前后两者就是并列关系的分句了，那么前面就要选A。
