分词的逻辑主语可以不是主句主语吗

问题描述

The launch came hours after US Secretary of State Rex Tillerson addressed a special meeting at the United Nations, calling for increased pressure on North Korea.

上句中的calling逻辑主语不是主句主语，这可以吗？再请问老师，came hours after是怎样的句法成分关系。 

老师答疑

曹老师：

The launch came hours after US Secretary of State Rex Tillerson addressed a special meeting at the United Nations, calling for increased pressure on North Korea.

句子分析：

主语：The launch

谓语：came

时间状语从句： hours after US Secretary of State Rex Tillerson addressed a special meeting at the United Nations, calling for increased pressure on North Korea.

时间状语从句再分析：

hours修饰连词after，为连词的状语

US Secretary of State Rex Tillerson：从句的主语

addressed:从句的谓语

a special meeting at the United Nations：从句的宾语

calling for increased pressure on North Korea：从句的状语（伴随状语），calling的逻辑主语为从句的主语。
