Answer 1

你好,这题的正确答案是:
以上答案都是错的,这个空不要填任何单词.
因为在这个句子中,he would forget all about eating and sleeping是句子的主句,已经完整了,
而When lost in work 是过去分词作时间状语,

追问

谢谢，不好意思原题是，When lost in work ,he often was ,____he would forget all about eating and sleeping.

追答

When lost in work ,he often was ,__when__he would forget all about eating and sleeping.
因为he often was 是主句了,,__when__he would forget all about eating and sleeping是一个定语从句

不填。
