题目
not until I remined him for the third time did he stop working and looked up.
请问,为什么要用“looked up",因为这里后面要用倒装,所以这里的look感觉应该和stop一样,用原型啊,因为都是在did倒装结构之后的动作,为什么要用过去式?难道两个动作时,后一个不用考虑倒装结构吗?
答案
not until I remined him for the third time did he stop working /
and looked up.
这个句子是一个并列句有两段,前半部分是使用了倒装,但这里的并列是顺接,虽是and但有先后关系（与then）意思基本一致.现停止工作,然后抬头.
