问题描述:

请问,(1)名词作定语是什么意思.
(2)什么叫相当于名词的词,短语,或从句充当 (答对在加分)
(3)-----enjoy listening to popular music
A.thirteen-year-olds Bthirteen-year -old
c.thirteen-years-old D.thirteen-years-olds

(1)名词作定语指一个名词修饰另一个词,这个名词就作了另一个名词的定语
如apple trees ,apple 是名词,修饰yrees ,作trees的定语
所以名词作定语大多时候就是指名词修饰名词的情况
即apple trees ,man docotor,shoe shops ,etc.
(2)有些短语(如what he said),句子(如he likes apple)
虽然它们是短语或句子,但换一下,它们就变成了具有名词性的短语或句子.
如I like apples .I like后面应加名词,但加短语同样也可以
I like what he said.what he said在这个句子中相当于名词
再如the fact is an apple.the fact 后面应加名词,但加句子同样也可以
the fact is that he likes apple.he likes apple在这个句子中也相当于名词
(3)13岁大,即13 years old 但中间加了“—”后,去掉表示复数的“s”
13岁的人可用thirteen-year-olds (在末尾加S,表示一类人)
所以选A
希望对你有用!
