Question

【题目】—Mr Green has _______ one-year-old son， doesn't he?
—Yes， and he also has ________ eight-year-old daughter.
A.a；a
B.an；a
C.a；an
D.an；an

Answer 1

【答案】C
【解析】句意：—格林先生有一个一岁的儿子，是不是？—是的，他也有一个八岁的女儿。表示“一……”是不定冠词a/an的用法，a用在以辅音开始的单词前；an用在以元音开始的单词前。One的第一个音[w]是辅音，前加不定冠词用a；eight的第一个音[ei]是元音，前加不定冠词用an。故选C。
