be/ fall asleep, sleep go/get to sleep, go to bed 这组词都与“睡”有关，但侧重点有所不同。 1.sleep 强调“睡觉”这一动作，是延续性动词，可与表示时间的状语连用。如： He slept for eight hours.他睡了八个小时。 Why couldn’t the man downstairs sleep? 楼下那个人为什么睡不着？ 2. be asleep表示“睡着”的状态，是系表结构，其中asleep不能用very修饰，只能用sound, first等词修饰。如： The baby is fast asleep.孩子睡得很香。 The little girl is sound asleep.这个小女孩睡得很熟。 3. fall asleep 意指“睡着”，表示一个动作的过程，侧重于“自然而然地入睡、不想入睡而不入睡”的含义。如： He was just falling asleep when there was a loud knock at the door. 他刚睡着，就有人使劲敲门。 I don’t know when I fell asleep last night. 我不知道昨晚什么时候睡着的。 而be asleep，“熟睡”，强调睡眠的状态，该短语在句中作谓语。例如： He Was asleep the moment after his head touched the pillow．他的头一挨着枕头（即一躺下）就睡着了。 One after another，all three of them fell asleep．他们三人一个接一个全都睡着了。 4. go to sleep 指“入睡、进入梦乡”这个动作，即begin to sleep。如： He was so tired that he went to sleep soon.他很累，不久就睡着了。 I just want to close my eyes and go to sleep as quickly as possible. 我正想合上眼，尽快地睡上一觉。 5. get to sleep意为“睡着、入眠”，强调进入睡眠状态，且多用于否定句、疑问句或条件句中。如： I was waiting for the sound of the other shoe! I can’t get to sleep.我在等另一只鞋的落地声！我睡不着。 go to sleep与get to sleep意义相近，均指“入睡，睡着”，强调进入梦乡的过程。两者均含有“开始睡觉”的意思，即begin to sleep．例如：I don't know when I went to sleep/got sleep last night.我不知道我昨晚什么时候睡着的。 6. go to bed 意为“就寝、上床睡觉”，只表示“上床去睡”这一动作，无“睡着”之意，它的对应词组是get up“起床”。一般说来，是go to bed在前，然后才go/ get to sleep或fall asleep。如： I often go to bed early．我通常很早就睡觉。 It's time to go to bed．该睡觉了。 He usually goes to bed at ten o’clock and goes to sleep/ falls asleep five minutes later.他通常十点钟就寝，五分钟后入睡。 One may keep healthy if he goes to bed early and gets up early. 如果一个人早睡早起，他就能保持身体健康。 7. in bed表示一种状态，在句子中常用作表语，意为“躺在床上，睡着”。其中in不能用on替换。 He is ill in bed．他生病卧床。 He stayed in bed till eight．他一直睡到八点。 练习： 1.
