题目内容
It is _______ unusual thing for us to find ________ UFO.
A．a; a B．an; an C．a; an D．an; a
D
【解析】
试题分析：句意:对于我们来说,发现一个不明飞行物是一件不寻常的事情. 结合语境可知前一空泛指任何一件不寻常的事情,故用不定冠词,unusual的词首音素是元音,故不定冠词用an. 后一空泛指任何一个不明飞行物,UFO词首音素是辅音,故不定冠词用a,选D.
考点：冠词
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。不定冠词用在名词前，表示泛指任何一个。定冠词用在名词前表示特指某一个。在专有名词及表示泛指的复数名词前一般不要冠词，叫做零冠词。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。
