1、thousand作名词是一千、数千、许许多多的意思，thousand与数词a、one、two等连用时，后面不加s。
2、比如，fi箪滹埘麽ve thousand acres5000英亩。若前面没有数目或数量，可用thousands (of...)，例如，There were thousands of people there. 那里有成千上万的人。
3、此外，the thousand是千位数，看例句，The cost ran into the thousands. 成本达到千位数。
4、Hundreds have been killed in the fighting and thousands made homeless. 数百人在战斗中丧生，成千上万的人无家可归。
