a11-year-oldboy
two-year-old作定语,前置twoyearsold：表语,后置
前者是adj后者是noun（复数）再问：都是什么意思我不是很理解为什么后边那个要加S代表什么含义再答：举例：asix-year-oldgirl一个六岁的小女孩six-year-olds一群六岁的孩子加
第一个相当于形容词‘11岁的’后要接名词第二个作表语,后不能接名词‘11岁’如Heisan11-year-oldboy.Theboyis11yearsold.
twoyearsold只可以做表语意思是两岁如Iamtwoyearsold.two-year-old只可以做定语意思是两岁的如Iamatwo-year-oldboy.但不可以互换再问：什么叫定语和表语
前者是13岁,作为名词讲；后者是13岁的,作为形容词讲
B用A应该说Sheis5yearsoldB是形容词,用来修饰girl
15-year-old可以做形容词,如a15-year-oldboy;15yearsold只能作表语,如heis15yearsold
是有区别的!thirteenyearsold相当于一个短语thirteen-year-old相当于一个形容词例如：theboyisthirteenyearsoldheisathirteen-year-
three-year-old为形容词,比如:mythree-year-oldsisterthreeyearsold为单词组合,比如mysisteristhreeyearsold.
10-year-old,意思是十岁的,是形容词,多用作定语,修饰名词.例如:Ihavea10-year-olddaughter.the10-year-old也可以用作名词.如:Heisthemostd
意思一样用法不同38-year-old形容词后跟名词,放句中38yearsold放在名词后如：sheis38yearsoldsheisa38-year-oldgirl
第一个只是形容一个事实,五岁sheisfiveyearsold第二个是一个形容词的感觉sheisafive—year—oldgirl.
Heisathree-year-oldboy.=Theboyisthreeyearsold.两者意思相同,简单地说,three-year-old可以看做是形容词,后面必须要加上名次.注意：three-
B10-year-old是复合形容词,它只能作定语,且里面的名词必须都用单数
year-old可以做形容词修饰名词,所以没有复数形式yearsold是两个独立的单词,year是名词所以有复数形式eg:iam10year-old=Iam10yearsold.
应该填写：
Eight-yearold=eightyearsold
13-year-old做定语,后面要跟名词,如：Heisan13-year-oldboy.但13yearsold就没有必要跟名词了,如：Heis13yearsold.不明白的再问哟,请及时采纳,多谢!
为你解答.11year（应该为复数years）old：作表语.如：Thegirlis11yearsold.（这个女孩有11岁了.）11-year-old：作定语,修饰名词.year是原形.Sheisa
