He was just falling asleep when there was a loud knock at the door. (《初中英语教科书》第三册, 人教社, p. 14)
《初中英语重点·难点纵横谈》(三)(中国科技大学出版社,p.29)说:
be asleep fall asleep } = 入睡
请问 be asleep 与 fall asleep 意思完全相同吗?
be asleep 与 fall asleep 的意思是不同的。前者的意思是“睡着”,表示的是静态,而后者的意思是“入睡”,表示的是动态(to go into a state of sleep = 由醒着到入睡的过程)。请对比:
-
Don't wake her up—she's fast/sound asleep. (ALD) 别吵醒她——她睡得很熟[很香]。
-
People who smoke in bed often fall asleep while they are smoking. 在床上吸烟的人,常常在吸烟的时候睡着了。
