My grandfather slept.The window was open.(合为一句)
3个回答

合并成一句时The window was open这句话就应该变成主句slept这个动词的伴随状态,而with能表示这种状态.所以My grandfather slept with the window open.with the window open这种结构在初中阶段你要多积累,比如:with the window closed.with the window on等等.这个结构中不能加was:My grandfather slept with the window was open这句话是错误的.
