再问： 第1题这个when引导的叫什么从句啊，是不是缺少成分啊
再答： 状语从句 不缺 Every teacher should, therefore, follow in his footsteps and emphasize benevolence when teaching. 因此，每个老师教学时，应效法孔子并强调仁的道理。 = Every teacher should,therefore,follow in his footsteps and emphasize benevolence when he teaches . 在以when,while,if, once ,though,unless 等六个连词引导的状语从句中，若主语与主句的主语相同时，可将从句中的主语删除，并将之后的动词变成现在分词。若是be动词，一律变成分词being,而being再予以省略。 1. when you do the work, you should be careful. = When doing the work, you should be careful. 2. If I am free, I'll do it. = If free, I'll do it. 3. when you do the work, you must be careful. = When doing the work, you must be careful. 4. Though he is poor, he is happy. = Though poor, he is happy. 5. While I was watching Tv, I fell asleep. = While watching TV. I fell asleep. 6. When you drive a car, you should be alert. = When driving a car, you should be alert.
