must i take the cold medicine three times a day?改为被动能去掉MUST吗?
改成was the cold medicine taken by me three times a day?
请问为什么呢
改成is the cold medicine taken by me three times a day?
当然不能去掉must了
建议你还是先把它改为陈述句的被动句,那就是
I must take the cold medicine three times a day.
the cold medicine must be taken three times a day by me.
所以变成疑问句就是
Must the cold medicine be taken three times a day by me.
你现在主要还是对变被动不熟,所以你可以先考虑变为陈述句,一旦你做得对子,就可以直接变了
