题目内容
20.--Look!Who's ___ old man over there?--Oh,he's my neighbor.He's ______ excellent doctor,though he's 86years old.( )
| A. | a; an | B. | the; an | C. | the;a | D. | a; a |
分析 -看,那里的那个老人是谁?
-哦.他是我的邻居.他是一个出色的医生,虽然他86岁了.
解答 答案:B.本题考查冠词的用法.根据语境可知,根据定语over there可确定old man是特指,应该用the来修饰.表示数量为"一"用a或者an来表示,表泛指,excellent首字母e的音素为元音音素,所以用不定冠词an来表达.故选B.
点评 做这种题时,根据语境和题意,首先确定考查的是冠词的用法;再就是要注意定冠词the表示特指,修饰old man;不定冠词a,an表示"一个",泛指;同时要注意元音音素前面要加不定冠词an.
