Can you see____?No.let's go and have a look.Maybe we can help them.<A.what was going on there ,b.what are they doing there c,what were they doing there d.what is going on there.说出理由为什么选d
d. what is going on there.宾语从句陈述句语序 用现在是

这是一个宾语从句,宾语从句用陈述的语序what在从句中作主语, is going做谓语,从let's go and have a look可以看出是正在进行的动作,故选d

可以用排除法。因为后边说，let's go and have a look,说明是现在事情，不是过去。首先排除A和C因为A用了was ，C 用了were 都是过去式。 另外，后边的回答有个NO 而如果选B的话，肯定不需要用NO 回答。。。所以D是毫无疑问的。
