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
第二句为什么不是强调句型?
答
1句意需要
2强调机构特点：去掉结构框架“it is/was···that”后余下部分句子结构完整.如果用强调句a job you are doing something serious but interesting.有多余部分了,即错句了.
