There used to be twenty million birds in the world,____(改为反意疑问句) 为什么要这样做?可以解释一下吗?
高手,help!
高手,help!
呵呵 要好好学语法哦
陈述部分的谓语是used to 时,疑问部分用didn't +主语或usedn't +主语。 He used to take pictures there, didn't he? / usedn't he?
这里是 usedn't there? 是不是觉得别扭啊 呵呵 这是对的
usen't there?
楼上说的要补充一下,
这句就不能用didn't .
因为疑问部分用didn't +主语 的只能是过去的动作。
而次句不是动作。 指这里过去有很多鸟。
There used to be twenty million birds in the world,usedn't there?
这里说的是这里曾经有200万种鸟。
There used to _____a bkkokcase in my room.
I was there和I used to be there有什么区别?
there are far more opportunities for young people that there used to be
