Question

–What do you think of teaching, Bob?

–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. Which C. When D. that

Answer 1

选A。where引导定语从句，而且可以用in which来代替。句意：它是这样一种工作，在工作中你所做的事情很严肃，可是又很有趣。你可能会考虑that，因为it is that可能是强调句。但是这里如果把it is that去掉就成you are doing something serious but interesting a job，显然不成立，所以不是强调句。而是定于从句，准确的应该是you are doing something serious but interesting（in）a job，需要介词。
