what do you think of teaching, Bob? ——I find it fun and challenging. It is a job( ) you are doing something serious but interesting.
A. where B. when
为什么答案选A,我选B,可以表示当你做的时候,觉得有点难但很有趣
答
其实是状语从句，意思是工作虽然做起来严肃但很有趣，
不是觉得有点难但很有有趣
答
它是个定语从句,因为从句中主语和宾语都有.所以先行词job 在从句中做状语指的是 in this job.在这种工作中,你做着严肃而又有趣的事,把 先行词job 放回到从句中就是：you are doing something serious but intereting in the job.
要注意的是不能认为where 指地点,它还可以指情况,形势,例子,等,只要是做状语,而先行词又不是the reason (这时关系词用why,),时间（用when),其他的都可用where 引导定语从句.
