What were you going to do yesterday?do 为什么可以原形

what did you go?what have you been going?what were you going?what have you gone?它们都有什么差别?如果语法有错请指出! what are you going? what are you going? What are you going. What were you thinking? what were you thinking. What were you thinking? What were you like? What You Were 歌词 What were you do? what were you doing? What were you dream? were,what,going,to,your,picnic,on,take,you(?)连词成句 What were you going to do yesterday?do 为什么可以原形 以下两句话有错误吗?可以这么讲吗?这两句话是虚拟语气.what would you feel if you were going to a party tomorrow?what would you do if you were going to a party tomorrow? What's the first thing you'd do if you were going to build a house?它是虚拟语气吗? what are you going?就是going Were are you going to do?改错
