in the bed和in bed的区别

in the bed和in bed的区别

in bed
表示“躺在床上、卧病在床”，短语中的bed不指具体的床，故前在不用冠词，in也不能改成on。
e.g. Do I have to stay in bed all day? 我必须整天呆在床上吗？
Reading in bed is bad for your eyes. 躺在床上看书对你的眼睛有害。

in the bed
表示在床里面，即在被窝里。

e.g. I was so tired and wanted to sleep in the bed right now.
"我太累了,真想马上躺在被窝里睡觉"

in the bed 东西在床上 in bed 卧病在床

in bed:卧床 on bed:在床上 两者主要区别在于前者强调躺着，不方便行走；后者只是陈述某物或某人在床上，强调的是人或物的位置。 on the bad和in the bad一般是特指一张床.

in the bed 是指【在床上】,就是一个位置 in bed 是指【卧病在床】,强调病了 例子： Tom is playing his Iphone in the bed.汤姆在床上玩他的Iphone. Jerry is staying in bed because he is ill.杰利生病了躺在床上.
