fall asleep 是一个常用的英语动词短语,主要含义为入睡、睡着,指从清醒状态进入睡眠状态的过程。其核心在于描述这个状态转变的发生,而非睡眠状态的持续(后者通常用 be asleep
或 sleep
表示)。
以下是其详细解释:
核心含义:进入睡眠状态
I couldn't fall asleep last night because of the noise.
(昨晚因为噪音我无法入睡。)The baby fell asleep in her arms.
(婴儿在她怀里睡着了。)语法结构与用法
fall
是不规则动词,其过去式为 fell
,过去分词为 fallen
。因此短语的时态变化为:fall asleep
(现在/原形) -> fell asleep
(过去式) -> fallen asleep
(过去分词,用于完成时或被动语态)。fall asleep
是一个不及物动词短语,后面不直接接宾语。不能说 fall asleep something
。fall asleep quickly/slowly
(很快/慢慢入睡), fall asleep at 10 pm
(晚上10点入睡)。fall asleep on the sofa/in class
(在沙发上/在课堂上睡着)。fall asleep from exhaustion/boredom
(因疲惫/无聊而睡着)。与相关词的区别
be asleep
/ sleep
: 这两个表达强调睡眠状态的持续。fall asleep
是进入这个状态的动作。He fell asleep at 9 pm.
(他晚上9点睡着了 - 动作) vs. He was asleep by 9 pm.
/ He slept soundly.
(他9点前就睡着了/他睡得很熟 - 状态)。go to sleep
: 这个短语的意思与 fall asleep
非常接近,常可互换,都指“入睡”。细微差别在于 go to sleep
有时更侧重“有意去睡觉”的动作,而 fall asleep
可能更强调“不知不觉睡着”的结果,但这并非绝对区分。来源:剑桥词典 (Cambridge Dictionary) 指出 fall asleep
和 go to sleep
都表示 "to begin sleeping"。常见语境与引申义
My leg fell asleep.
(我的腿麻了。)
fall asleep
的核心意思是“入睡”,指从清醒状态过渡到睡眠状态的那个动作或过程。它是一个常用的不及物动词短语,使用时需注意其不规则动词形式 (fall - fell - fallen
)。理解其与 be asleep
(持续睡眠状态) 的区别是关键。该短语主要用于描述人或动物开始睡觉的情景。
字面含义
“fall asleep”由动词“fall”(进入某种状态)和形容词“asleep”(睡着的)组成,直译为“进入睡眠状态”,强调从清醒到入睡的瞬间动作。其核心含义是“自然或突然地睡着”,常隐含无意识或非计划性的入睡。

“Fall asleep”是英语中描述“入睡动作”的核心表达,其语法特点(不及物性、时态变化)和语义侧重(无意识/突发性)需特别注意。在写作或口语中,需根据语境选择“go to sleep”(主观意图)、“be asleep”(持续状态)等同义词,避免混淆。该短语的灵活运用能更精准地传递睡眠相关的细微差异。
