他昨天直到完成作业才看电视 He ___ ___TV ____he finshed his homework yesterday 中间空白处应填什么??

didn't watch until

had not watch until

这个句子用的是过去完成时，所以前面也应该用过去完成时的否定形式！

填didn`t watch until

didn't watch until

didn't watch until
这句话考的是not...until的句型，就应该这样写。

我同意楼上的观点，这题考察的就时not.....until的用法，所以回答应该时didn't watch....until
