had been in use是被动语态吗

问题描述

精选答案

had been in use不是被动语态但表达被动意思，相当于had been used。

中文意思是“被使用，开始使用”例如，英语老师告诉我们孔明灯在三国时就已经开始使用。The English teacher told us that sky lanterns had been used /in use when he was in the Three Kingdoms.从历史书上我们了解到火药最早在中国使用。We knew from the history books that gunpowder had first been in use/used in China.
