looking at his watch,he saw that it was one o'clock.
问题描述：
looking at his watch,he saw that it was one o'clock.
这句话用的是什么形式呢?非谓语动词作状语吗?若写成he looked at his watch and he saw that it was one o'clock 这样意思有变吗?为什么要用非谓语动词的形式写呢?
答
现在分词作伴随状语,表示同时发生.（可以认为非谓语动词作状语）
改成两个句子也对,意思不变.那我把他们的位置这样改一下呢he looked at his watch，seeing that it was one o'clock这样有错吗？ 那他表达的意思跟原句也完全没变化吗？he looked at his watch: it was one o'clock。这样就好了。虽然你的语法上是对的。但是有点儿赘余。
