Our teacher entered the classroom,book in hand.

问题描述:

Our teacher entered the classroom,book in hand.
另一句是Our teacher entered the classroom,with a book in his hand.
为什么两句伴随状语要不同呢?

这两句话的含义基本一样,老师手里拿着书走进了教室.
伴随状语的不同用法,用with引导的名词前要加冠词或人称代词,而没有with引导的明此前就不需要任何修饰词.eg:The boy ran into the room,with his nose red.
