be asleep/go to bed/go to sleep/get to sleep/fall asleep
第一应了解sleep是动词,asleep是形容词。
⑴ be asleep指睡着的,睡熟的。比如:
He is asleep.
他睡着了。
⑵ go to bed指上床, 就寝。比如:
What time did you go to bed last night?
昨天晚上你什么时间上床睡觉的?
⑶go/get to sleep和fall asleep意思接近,都指入睡,睡着, 但get to sleep常用于否定句中。比如:
I went to sleep quite late last night.
我昨晚睡着非常晚了。
