七年半英语怎么说两种

"七年半" (qi1 nian2 ban4) 可以说作 "seven and a half years" 或 "seven years and six months"。

其中 "seven and a half years" 是将 "七年半" 直接翻译成英文，而 "seven years and six months" 则是将 "七年" 和 "半年" 分别翻译成英文。

例句：

I've been working here for seven and a half years. (我在这里工作了七年半。)
He's been studying English for seven years and six months. (他学习英语已经七年半了。)
