years与year的区别

问题描述

精选答案

year和years的区别：years是year的复数形式，year是一年，years是很多年,另外大于一岁就用复数yearsold，若刚好一岁及以下就用yearold。

例句It's a four-year course.这是一个为期四年的课程。He has been here for four years.他在这已经待了四年了。year old和years oldyear old只能是he is only one year old.即years old的单数形式。years old就是一岁以上的了,例如she is three years old.year old 和 years old通常都作表语。
