直接引语改间接引语时何时需把从句中的一般过去时改成过去完成时,具体问题如下
he said that his car ___(被偷了)and that he would have to telephone the police
此处勇was stolen 还是had been stolen还是都可以

The visiter said that he ___very gald to visit our country
此处勇was 还是had been还是都可以

they asked me ___（我如何通过两天前的考试） 问题同上

还有是把two days ago变成two days before就一定要变成过去完成吗
