Question

一道英语语法选择题？

答案是选A，可以详细解释下吗！！

Answer 1

这道题考察的是独立主格结构，分词作原因状语，因为分词逻辑主语和主句主语不一样，所以带上自己的主语。

Answer 2

选d,句子前或后要加连词，since there was no bus,we had to walk home.或者
there was no bus, so we had to walk home.如果选b,c，句子中的主语就是分词的逻辑主语，不是我们有不有车所以选A,there being no bus.是独立主格结构！

Answer 3

D. 错误的原因是缺少了一个连词because。
A. There 是非谓语动词being 的逻辑主语。
全句可以改成普通形式:
Because there was no bus , we had to walk home.

Answer 4

there being no bus 表示原因
作状语的there be 形式，通常用“there being”结构。
例如：There being nothing else to do ,we went home.因为没有其他事可做，我们就回家了。
They closed the door ,there being no customers.因为没有顾客，他们的店关门了。

Answer 5

having no bus原因状语
