【题目】 new study says that going to bed late is harmful to our health.

A. /;/ B. A;/ C. A; the D. The ; the

【答案】B

【解析】

句意:一项新的研究表明,晚睡对我们的健康有害。考查冠词。a/an是不定冠词,表示泛指,a用于以辅音音素开头的单词前面,an用于以元音音素开头的前面;the是定冠词,用于特指。第一个空格,一项新的研究,是泛指,而且new是以辅音音素开头的单词,所以用a;第二个空格,go to bed上床睡觉,是固定词组;因此这句话的意思是:一项新的研究表明,晚睡对我们的健康有害。故答案选B。
