now i think it's time you handed in your exercise book.这里为什么用handed?hand接in是习惯用语吗?

hand in 是词组,上交的意思
这里涉及到一个句型
It's time + （that）从句从句用过去时
表示该做某事的时候了
所以这里的hand才要用过去时 handed
表明这是你该上交作业的时候了
祝你进步
再问： It's time + that clause 时，that可省略，time可由about修饰，从句中的谓语动词有两种形式，或者用动词的过去式(be用were)；或者用shoud + 动词原形（should不能省略)。此句型为虚拟语气句型，表示“现在某人该做某事了”。含有该事早该去做而未做，现在去做似乎都为时已晚的意思。
