答案
D
解析

试题分析:句意:布莱克先生伤到了左腿.他刚做了一个x光检查.医生说他需要一个手术.结合语境可知第一空泛指任何一个x光检查,x词首音素是元音,故不定冠词用an.第二空特指为他看病的医生,故用定冠词.第三孔特指任何一个手术,故用不定冠词,operation词首音素是元音,故不定冠词用an.选D.
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。
