Arriving at the bus stop, ____ waiting there.

Arriving at the bus stop, ____ waiting there.
A、he found a lot of people
B、a lot of people were
C、he found a lot of people’s
D、people were found
【正确答案】：A
【题目解析】：本题测试非谓语动词。由于句子是以现在分词arriving开头，所以后面主句的主语应该是he，由此可以排除B和C两项。另外，“find sb doing sth”中的sb不用所有格。因此A为正确答案。本句的意思是：“到达公共汽车站后，他发现有许多人在等车。”
