问题描述:

When deeply absorbed in work,____he often was,he would forget all about eating or
sleeping.A.that B.which C.where D.when 答案给的which

这里的which指代整个主句。

When deeply absorbed in work,which he often was,he would forget all about eating and sleeping. 他经常聚精会神地工作,这时他会废寝忘食。

选择B
是因为这里也是一个定语从句,不过这里的定语从句修饰的是前面整个句子
which表示的就是前面整个句子的意思
当沉下心工作后,他经常这样,他会忘了吃饭和睡觉
