chinese must have large number of speaker?反问

don't they

表一定时就这样；

表必须时，就用needn't ;

don't they

是反问还是反义疑问啊..

hasn't they?
我们英语老师讲过这个语法点，把这句话还原成陈述句，是Chinese has large number of speakers,那么反义疑问句就是hasn't they?

亲啊~~你确定你的原句是对的？
为什么是chinese ，貌似应该是china吧
还有应该是speakers吧~~speaker是可数名词

我想应该是china has large number of speakers,doesn't it?
