1.Shall we go on a picnic this weekend ------Good idea ,unless it ________(为什么用rains ,而不用won't rain不是将来是吗?)
2.What did you ________about Nanjing (为什么不是talk 而是say)
3.Whether he comes or not ______nothing to me(为什么用is不可以用are,has have)
4.Did you seeMr.Gree when you were in France?——No ,when I______France ,he had gone to China (为什么要用got to而不用had arrived to h或had got to )

1.unless 引导的条件状语从句（虚拟）,虽然有将来之意,仍要用现在时.
2.这里有what引导的特殊疑问句,做say 的宾语.而talk 是不及物动词不好直接节宾语.要接的话要加about .但这里的 about nanjing 是一个独立的.而不是要和talk 搭配.注意别被误导.
3.由whether……or not 引导的从句做主语,句子谓语动词用单数.
4.这句是对时态的考察.主句是过去完成时 he had gone to ……,
从句要用过去时.所以用when i got to
下次就会自己做了.
