addressing the issue 在这里这里作说明成分?development of environment addressing the issue或咋断句
they have played a key role in the development of environment addressing the issue
答
此句句型为 sb.do sth.doing sth.
其中addressing the issue为后置定语修饰主语they
短句在environment 和addressing中间断开即可谢谢，再问您另一个问题how did the campaign know which readers to send ads to 。 这句话的两个to怎么理解？ 不知能不能举几个to的这种用法句子，
