状语现在分词作状语还是动名词作状语？

问题描述

After having spent 3 hours in the shop，she went back home.

请问老师前面部分是分词做状语还是动名词作状语，怎么判断呢？

若二者均可做状语，有何异同呢？

谢谢您。

老师答疑

刘老师：

简要解答你的疑问：

After having spent 3 hours in the shop, she went back home.

你给的这个句子中，After having spent 3 hours in the shop是介词短语，作时间状语。

如果去掉介词after，则是现在分词短语，同样作时间状语。意思不变。

【提示】having spent 3 hours in the shop：加了介词是动名词，不加介词是现在分词。

感谢老师。谢谢。
