2千用英文怎么说,为什么不加s
时间：
"2千"用英语表示为"two thousand". 不加s是因为thousand是数词，不像形容词和名词那样需要加-s来表示复数。
数词的复数形式通常不变，无论是几千还是几百万，都不加-s。这是英译经典数字的规则，已经形成了固定习惯。
例如：
The company made a profit of three thousand dollars last year. (公司去年获得了3千美元的利润)
She has saved up five thousand euros for her trip. (她为旅行储蓄了5千欧元)
The population of the city is over two milpon. (这个城市的人口超过200万)
