bed前用介词和冠词的习惯问题

bed前用介词和冠词的习惯问题

请看下面两个句子：

a. It is a bad habit to read __________ bed.

b. It is a bad habit to read __________ the bed.

A. in, in                B. on, on               C. in, on                D. on, in

此题应选C，容易误选A，B。关于bed(床)这个词，要特别注意它与冠词和介词连用的情况：

1. 一般说来，表示与“睡觉”这一概念有关时，通常不用冠词或其他限定词，反之则用。如：

It is too early for bed. 现在睡觉太早了。

He went to bed at ten last night. 他昨晚10点上床睡觉。

He went to the bed and found a letter on it. 他走到床边，发现上面放着一封信。

He sat by the bed, watching TV. 他坐在床边看电视。

2. 与介词in连用时，习惯上不用冠词; 而与介词 on连用时，习惯上要有冠词。如：

He is still in bed. 他还在睡觉。

He is sick in bed with a cold. 他因感冒而卧床。

There is a box on the bed. 床上有个盒子。

有时两者都可以用，只是搭配不同而已。如：

躺在床上看书是个坏习惯。

正：It is a bad habit to read in bed.

正：It is a bad habit to read on a [the] bed.

3. 与介词into, out of 等连用时也通常不用冠词。如：

He got into bed quickly. 他很快上了床。

He jumped out of bed as soon as he heard thebell. 他一听到铃声就跳下了床。
