Question

All of a sudden,the thief walking behind a young and pretty lady ---her purse,-----into the crowd.

为什么这里不能填seized 和rushed 我难道不可以表示两个动作紧接着一个接一个吗，为什么非要用分词作状语

Answer 1

D. seized; rushing

-ing形式作状语，可以表示时间、原因、结果、条件、让步、行为方式、伴随状况等。
如：
1.doing sth.作时间状语：Seeing my parents waving in the crowd，I went running to them.
2.doing sth.作原因状语：Being a teacher，you should help your students in every way.
3.doing sth.作结果状语：
Mary failed all her exams, making both her parents very angry. 玛丽未能通过一门考试，这是她父母非常生气。
The child slipped and fell, hitting his head against the door.
Her husband died ten years ago, leaving her with three children to look after.

4.doing sth.作条件状语：

Listening to English every day（If you listen to English every day），you’ll learn it well step by step.

5.doing sth.作让步状语：
Working so hard, he failed again.
Living miles away, he attended the course.虽然住在几英里以外，他仍去上课。
6.doing sth.作方式状语：
The children ran out of the room, laughing and talking merrily.
7.doing sth.作伴随状语：

All night long he lay awake, thinking of the problem.
The six blind men stood there begging for a meal.

He sat in the armchair, reading a newspaper.
英语中V-ing形式作伴随状语时,它表示的是一个次要的动作,来对谓语表示的动作加以说明或作为陪衬。一般将其置于句后,可用逗号与主句成分分开。

你的例句就是doing sth.作伴随状语，rush是一个次要动作，来对seize动作加以陪衬。其表现力比并列句要强，并列句也对，中国学生理解感觉差不多，在地道的英语上，用doing sth.作伴随状语，会比较书面化和正式化。这是英语的进阶路上会经常遇到的，为什么不用简单的，要用绕口的。
