题目

单选 When deeply absorded in work,he often was
When deeply absorbed in work,____he often was,he would forget all about eating or
sleeping.A.that B.which C.where D.when
用what可以吗,为什么.

答案

不.这是定语从句,不是名词从句.
先行词是When deeply absorbed in work,
=he was often (absorbed in work)...
absorbed不是absorded
当他全神贯注于工作,他经常是这样的,他会废寝忘食.
