Question

英语语法选择？

Arriving at the airport, ______ waiting for the security check.
A．a lot of people
B．a lot of people were
C．people were found
D．she found a lot of people

Answer 1

首先，arriving at the airport是现在分词短语作时间状语，arriving 这个动作的发出者和后半句的主语必须是同一个人。根据句意，本句可补充省略部分：When she was arriving at the airport, she found a lot of people waiting for the security check. 当她到达机场的时候，她发现许多人正在等待安检。主句和时间状语从句的主语都是同一个人she。 由此可以把选项ABC都排除了。
现在分词短语作状语的例子：
Seeing their teacher, the students stood up.
=when they saw their teacher, the students stood up.

seeing 这个的动作发出者和后半句的主语the students 是一致的。
