问题描述:
His little brother is ( ) a) five years old b)five-years-old c)five-year-old d) five-year-old
答
c
答
选A
答
选A five years old
five-year-old=five years old
前者是附和名词作定语修饰另一个名词 例如:he has a five-year-old son.
后者是系表结构里的表语 例如:his son is five years old.
答
A
five-year-old 只能放在名词前作定语,“五岁大的”。不能放be动词后作表语。而且有连词符时,year必须用单数。
即 His little brother is five years old. = His little brother is a five-year-old boy.
