bed前用介詞和冠詞的習(xí)慣問題

請(qǐng)看下面兩個(gè)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

此題應(yīng)選C，容易誤選A，B。關(guān)于bed(床)這個(gè)詞，要特別注意它與冠詞和介詞連用的情況：

1. 一般說(shuō)來(lái)，表示與“睡覺”這一概念有關(guān)時(shí)，通常不用冠詞或其他限定詞，反之則用。如：

It is too early for bed. 現(xiàn)在睡覺太早了。

He went to bed at ten last night. 他昨晚10點(diǎn)上床睡覺。

He went to the bed and found a letter on it. 他走到床邊，發(fā)現(xiàn)上面放著一封信。

He sat by the bed, watching TV. 他坐在床邊看電視。

2. 與介詞in連用時(shí)，習(xí)慣上不用冠詞; 而與介詞 on連用時(shí)，習(xí)慣上要有冠詞。如：

He is still in bed. 他還在睡覺。

He is sick in bed with a cold. 他因感冒而臥床。

There is a box on the bed. 床上有個(gè)盒子。

有時(shí)兩者都可以用，只是搭配不同而已。如：

躺在床上看書是個(gè)壞習(xí)慣。

正：It is a bad habit to read in bed.

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

3. 與介詞into, out of 等連用時(shí)也通常不用冠詞。如：

He got into bed quickly. 他很快上了床。

He jumped out of bed as soon as he heard thebell. 他一聽到鈴聲就跳下了床。
