6.was;seen;helping;by;Miss;King.方法同5题。当主动句中的主语做被动句的宾语时，其前用介词by。

5.was; eaten.根据变被动语态的时态结构公式，很明显答案为：was; eaten.

4.be ; spoken.根据含有情态动词的主动句变被动句的变化规则。答案为：be; spoken

3.he; had; bought.根据直接引语变间接引语时态的变化规律，得知：间接引语中应用过去完成时。

2.if/whether; I; was.本题考查的是一般疑问句的直接引语变间接引语，时态由一般将来时变为过去将来时；第二人称的you 要和主句中的宾语一致，为I。

1.if/whether; was; that day.本题考查直接引语是一般疑问句时变间接引语的引导词为　　　　 if/whether;时态做相应的变化，即一般过去时。时间状语today变为that day.
