选择题
My daughter is only ___________. But you are a ______________girl. She can’t understand those passages in the newspaper.
A．five-year-old, sixteen years old
B．five years old, sixteen-year-old
C．five-year-old, sixteen-years-old
D．five years old, sixteen years old
答案
答案：B
题目分析：英语复合词中的单词一般为原型,其作用相当于一个形容词;在表示具体年龄时,year有单复数的变化.句意:我的女儿只有五岁.但是你是一个十六岁的女孩.她不能明白这些报纸中的段落.结合语境可知前文表示具体年龄,下文为复合词做定语,故选B.
点评：数词+years+old在句子中一般做表语；数词+year+old可构成复合词作用相当于形容词，一般用作定语。
