题型：不详难度：来源：

It took me _______ hour to finish my homework.
A.a B. an C. the

答案

解析

试题分析：句意：完成我的作业要花费我一个小时的时间。结合语境可知本句中泛指任何一个小时，故用不定冠词。Hour词首音素是元音，故不定冠词用an。选B。
点评：冠词是一种虚词，一般用于名词前面表示特指或者泛指某一个。冠词的应用都用一定规则，熟记这些规则是解题的关键。需注意的是不定冠词的用法是看词首音素，不是看首字母，如：useful首字母是元音，但是词首音素时辅音，故不定冠词用a；hour首字母是辅音，但是词首音素是元音，故用冠词an。
