题型:不详难度:来源:
This is _______ empty bottle. But it is  _______useful one.
A.a; aB.an; aC.an; theD.a; an

答案
B
解析

试题分析:句意:这是一个空瓶子。但是他是一个有用的瓶子。结合语境可知前文泛指任何一个空瓶子,故用不定冠词,empty词首音素是元音,故不定冠词用an。下文泛指任何一个有用的瓶子,也用不定冠词。Useful词首音素是辅音,故不定冠词用a。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。
