过去分词做后置定语前面可以有逗号么

问题描述

Microsoft is counting on Windows 10, launched in July, to help it win a bigger share of the market for tablets and smartphones, now dominated by Apple Inc and South Korea's Samsung Electronics Co Ltd. 

疑问：这句中红色部分是过去分词做定语么？与做状语如何区分？

老师答疑

曾老师：

句中launched in July和now dominated by...均为过去分词短语作定语。

过去分词做后置定语前面可以有逗号，相当于被动语态的非限制性定语从句,对先行词作补充说明。如：

The business, founded by Dawn and Nigel, suffered financial setbacks.唐和奈杰尔创办的企业在资金上遇到了一些问题。《柯林斯高阶英汉双解学习词典》
