Question

we are living in an age （ ）many things are done on computer .

填什么？原因？
( )里填in which，during which 行吗？原因？
若将in which，during which还原到原句中是怎样的

Answer 1

填when\in which\ during which 都可以；
定语从句中缺少时间状语，所以用 in + which 或者 during+which 或者 when 来引导都可以。
还原到句中就是：in the age many times are done on computer.
