Question

单选。请解释一下。It was___that caused him to serve dinner an hour later than usual.

It was___that caused him to serve dinner an hour later than usual.
A. we being later B. our being late C. we were late D. because we were late

Answer 1

正确答案是B。这是强调句型，强调是的主语our being late.这是个动名词的复合结构作主语。
强调句型的判断方式就是把框架it was/is...that去掉后仍能组成完整的句子。所以这句话还原后就是：Our being late caused him to serve dinner an hour later than usual.
其他的选项还原后句子不成立。
because引导状语从句是不可以作主语的。A和C形式不对。

希望你能满意这个解释，祝学习愉快！

Answer 2

选B
A和C很容易排除了。
这个句型是强调吧，强调原因，因此用because不合适
感觉高中的时候做过类似的题

Answer 3

AC肯定不对，BD似乎都有道理，偏向于D，看哪位可以帮忙一下。

第47个浪人 能解释一下为什么D不对吗？非常感谢！

Answer 4

B. our being late
这是强调句，强调部分是主语our being late （动名词的复合结构，“我们迟到”）
