Tom and I playling football.(改成一般疑问句）Are Tom and you playing football?为什么不用does而用are
答
现在进行时 是be+Ving结构
改为疑问句的时候 be 动词提前
Tom and I playling football.少了are 应该是Tom and I are playling football.
答
Tom and I playling football
其实你这句话本身就有错误
应该是 Tom and I are playling football
一个句子中必须要有谓语
当句子有be动词的时候
一般疑问句都是将be动词提前
如果是用does
那原句的前提是没有be动词
