She is accustomed to reading on bed till mid-night. (全国研考)
标准答案要求将 on bed(C) 改为 in bed. 据我所知, 表示“睡觉”的意思时才用 in bed, 上道题是说“在床上读书”, 并不是说“睡觉”, 那为什么也要求用 in bed 呢?
不错, in bed 常常表示“睡觉”的意思。例如:
-
It's ten o'clock in the morning but he's still _. A. at the bed B. at bed C. in bed D. in the bed(Nelson, 300C)
-
I sometimes stay in bed until lunch time. (New Concept English, Book 2) 有时我一直睡到吃午饭。
-
That night we were in bed early. (Snow) 那天晚上我们睡得很早。
-
He lay in bed beyond his usual hour. 他比往常睡得时间长。
但是, in bed 也可以指脱掉外衣或盖被子躺在床上读书或思考问题。例如:
I prefer to remain in bed and dream on undisturbed. 我喜欢躺在床上独自静静地遐想。
on the (a) bed(注意:必须有冠词)则是在具体的床上,没有“睡觉”这一抽象含义。与之搭配的动词有 sit, lie, lie down 等:
-
Joe sat on the bed while Martin unpacked. (London) 乔坐在床上，而马丁在打开包裹。
-
He took off his shoes and stretched himself out on the bed. 他脱了鞋，在床上伸直了身子。
-
Lie down on the bed. (CGEL) 在床上躺一躺。
-
Would you like to lie down on the bed for a few minutes? You look rather tired. (LDPV) 请你上床躺几分钟吧！你显得有点儿疲倦。
-
lie on a bed of thorns 如坐针毡
