Question

有关英语语法的一个问题

"we know that chronic pain can disturb a person's life ,causing problems that range missed work to depression." 请问句中的causing为什么是分词形式？

Answer 1

Causing 在句中做结果状语，相当于省略的定语从句，原句可以是which cause ……,把which 省略了，所以就用causing.

Answer 2

we know that chronic pain can disturb a person's life ,causing problems that range missed work to depression.
这是现在分词 作宾语从句中的伴随状语 其逻辑主语 是宾语从句的主语pain
是主动关系 故 用 现在分词
原句=chronic pain can disturb a person's life and cause problems that range missed work to depression.
