Question

___enough time ,we did not finish the work

Anot　there　being　Bthere being not C there not being D there was not 为什么选择C　而不是选D

Answer 1

你好。你的句子是表明原因的独立主格结构。变成原因状语从句就是：As there was not enough time, we didn't finish the work.或者：There was not enough time, so we didn't finish the work. 就是说，如果选D,句子里必须要有as / so这样的连接词来连接前后两句。
又如：As Mike has fallen ill,I have to finish his part of the work(这是原因状语从句)请你变成独立主格结构：
Mike having fallen ill,I have to do his part of the work.

Answer 2

there not being enough time ,we did not finish the work. 此句子中 1. 没有连词，或起连接作用的词和短语。 2. 句中 是用 逗号 连接。 在英语中 逗号 不能连接句子。 所以我们可得 横线处要用非谓语形式。
如想选D 可说为 there was not enough time ,so we did not finish the work.

Answer 3

___enough time ,we did not finish the work
选C
因为这是一整句话，只能有一套主谓宾，如果用D的话，就有两个谓语了
一个是【did not】，一个是【was not】，所以只能用非谓语
否定结构是加在非谓语前面的
