英语语法请问这三个句子都有独立主格结构作伴随状语 如果这三个句子都加上连词改为非独立主格结构应该怎么改呢?Mr.Smit

Mr.Smith flew to New York thismorning,and his assistant is to join him there this Saturday.
2．He was lying on the grass,and his hands were crossed under his head.
3．He stood on the deck,and the pipe was in his mouth.
改为非独立主格结构就是要加上连词,把独立主格结构改成句子,句子要有谓语动词,因此还要要加上谓语动词.
