asleep · 语义深度解析

核心

睡着的——只作表语，不能前置修饰名词

asleep 的核心义：处于睡眠状态。句法限制与 alive 相同：只作表语，不能前置修饰名词（× asleep baby → ✓ sleeping baby）。关键搭配：fall asleep（入睡，最高频：fall asleep in class = 在课堂上睡着了）；fast/sound asleep（熟睡：fast asleep = 睡得很熟）；be asleep（处于睡眠状态，与 be awake 相对）；half asleep（半睡半醒）；pretend to be asleep（假装睡着）。注意：asleep 是状态（已睡着），sleep 是过程（睡觉），不可混用。

释义

1

adj.（表语）睡着的，熟睡的

The children were fast asleep by the time their parents returned from the evening event.

他们的父母从晚间活动回来时，孩子们已经熟睡了。

语感

asleep = 只作表语（× asleep baby → ✓ sleeping baby）；fall asleep（入睡）；fast asleep（熟睡）

睡着的，熟睡的（只作表语）

句法对比（重要）：asleep（表语：the baby is asleep）vs. sleeping（可作定语修饰名词：a sleeping baby = 熟睡的婴儿；也是动词进行时）。固定表达：fall asleep（入睡，最高频；不说 × fall to sleep）；fast asleep / sound asleep（熟睡：were fast asleep = 睡得很熟）；drift off to sleep / drop off to sleep（渐渐入睡，书面）；go to sleep（去睡觉，较口语）；put sb. to sleep（哄某人入睡；也可指安乐死动物）；half asleep（迷迷糊糊）。

陷阱

⚠️asleep 只作表语，定语修饰名词用 sleeping

✗

The nurse checked on the asleep patient every hour throughout the night to monitor his vital signs.

护士整夜每小时检查一次正在熟睡的患者，以监测其生命体征。（× asleep patient → ✓ sleeping patient）

asleep 是表语形容词，不能前置修饰名词；修饰名词 patient 用 sleeping；× asleep patient → ✓ sleeping patient

✓

The nurse checked on the sleeping patient every hour throughout the night to monitor his vital signs.

护士整夜每小时检查一次熟睡的患者，以监测其生命体征。

⚠️fall asleep（入睡）vs. go to sleep（去睡）

Despite the noise from the street, she managed to fall asleep within minutes of lying down.

✗

fall asleep = go to sleep（去睡觉，两者一样）

✓

fall asleep（自然入睡，通常是无意识地进入睡眠状态：fell asleep on the bus = 在公车上睡着了）；go to sleep（有意识地去睡觉：I'm going to go to sleep now = 我要去睡觉了，含主动意图）；fall asleep 强调「进入睡眠的那个时刻」（常含意外/不由自主义）；此句 fall asleep within minutes = 几分钟内就入睡了，正确

尽管街上嘈杂，她躺下几分钟内就入睡了。（fall asleep = 自然入睡；go to sleep = 有意识地去睡觉）
