如:
●I could not decide which dictonary to buy. =I could not decide which dictionary I should buy.
●Jack did not know where to find such a good teacher. =Jack did not know where he could find such a good teacher.
疑问词+to do 应该翻译成什么意思?to do表示接下去要做的事?这结构在转化成从句之后,从句里的情态动词要用什么?很多时候看到是should,但也发现有could,will等,不清楚怎么回事,老师跟我讲讲好吗?谢谢!
