Question

2. ______, we missed our train the day when we were back to Paris.

A. With the bus late B. The bus to be late
C. The bus being late D. The bus was late
为什么选c being?

Answer 1

正确答案选 C, 这是 -ing 形式作独立主格结构的一种用法。
The bus being late, we missed our train the day when we were back to Paris.
= Because the bus was late, we missed our train the day when we were back to Paris。
不少同学会选择 D 项，但你对比以上两句就知道它的错误。
英语中，一个简单句只有一个主谓结构，如果一个句子出现两个主谓结构，则或者是并列句，或者是复合句。并列句如: The bus was late and we missed our train ......
独立主格结构在高中英语课本上并没有作为专题教学，但练习中有时会出现。独立主格结构是一个短语，不是一个分句，该短语有自己的逻辑主语，但短语内部没有谓语，在全句中独立主格结构一般作状语。再举一例：He came into the classroom, book in hand. 这句中的 book in hand 就是独立主格结构，book 是逻辑主语。

Answer 2

C. The bus being late
