问题描述:

After___,he can play the piano very well.
A five years learn B five years'study
C five-years learn D five-year study,理由

C

d “五年的学习”,这个“五年的”是形容学习的时间,但又不能用所有格,所以用连字符“-”在five和year中表示,而用了连字符后,year后面就不用加复数了,规定来的,记住就行了。再举个例子:
She is a two-year old girl

D老师讲过

D数字与年连一起不加s,study可以是名词,learn不能是名词

B 经过了五年的学习之后,他能弹钢琴弹得很好.
‘‘五年的’’要用名词所有格的形式
并且五年在没有连接线的情况下用复数
