音标
英音：[ɡəʊ tə sliːp]，美音：[ɡoʊ tuː sliːp]

核心含义
强调“入睡”的过程或结果，即从清醒状态进入睡眠状态，而非单纯“上床”的动作。例如“十点上床，但直到午夜才睡着”需区分：I went to bed at ten, but I didn't go to sleep until midnight 。此外，口语中可表示“（肢体）麻木”，如长时间保持同一姿势后手脚发麻。

用法辨析

与go to bed的区别：前者强调“睡着”，后者仅表示“上床”这一动作，不一定入睡。如“我今晚要早点上床”用I'm going to bed early tonight，而“她饭后很快就睡着了”用She went to sleep quickly after dinner 。

与fall asleep的异同：两者均表示“入睡”，但fall asleep更侧重“自然进入睡眠”，有时含“无意入睡”之意；go to sleep则可指主动尝试入睡。例如“婴儿吃饱后通常会睡着”用Your baby usually goes to sleep after a feed 。

短语搭配

go to sleep early/late：早睡/晚睡
I always go to sleep early on weekdays（工作日我总是早睡）

go to sleep quickly/easily：快速/容易入睡
She went to sleep quickly after reading a storybook（她读了故事书后很快入睡）

have trouble going to sleep：难以入睡
He had trouble going to sleep last night because of the noise（昨晚噪音让他难以入睡）

go to sleep with sth. on：开着某物入睡
I go to sleep with my bedroom light on（我开着卧室灯睡觉）

例句

I don't know when I went to sleep last night

我哄得她睡着了。
I got her to go to sleep

别说话了，赶紧睡觉。
I told them to be quiet and go to sleep

常见误区

错误：用“go to sleep”表示“去睡觉”（仅指上床）。

正确：“去睡觉”用“go to bed”或俚语“hit the hay/sack”，如I'm ready to hit the hay（我想睡觉了）。

经典引用
“Now I shall go to sleep. Good night.” ——George Byron（美国作家乔治·拜伦）

记住：谈论“上床”用go to bed，描述“睡着”用go to sleep，别再混淆这对“睡眠搭档”了！
