3.He ___me he never ____(write) letters to anybody.

1.does ,tell ,will buy
2.says ,cannot
3.tells ,has never write
4.do ,say ,are
5.says ,will wait

答案

第一个错了：When did he tell you that he bought this car?
第二个应该用过去式吧?.He said he couldn't understand me.
第三个错了：He told me he never write letters to anybody.
第四个后面应该是将来式吧.Why do you say that you will be busy?
