The little girl looks pretty,doesn't she?does和is有什么区别?
只要看前面的句子有没有be动词的相应形式（is are was were等）就可以了
如果有,就用它的否定形式（如is变isn't）
如果没有,就用助动词do

is 是主动词 dose是行为动词……
这里对looks反问 自然用doesn't

上面这句话后半部分是反意疑问句，它的构成需要考虑两方面的因素：
1.前半句是肯定还是否定
如果前半句肯定，后半句一定采用否定形式；反之，如果前半句表达否定意义，后半部一定用肯定形式。

如果前半句采用主系表结构，后半句也同样用主语和系动词的形式，只不过，后半句毕竟是问句，注意语序即可；
如果前半句采用了实义动词，后半句则需借助助动词来构成...

上面这句话后半部分是反意疑问句，它的构成需要考虑两方面的因素：

2.前半句的谓语部分

如果前半句采用了实义动词，后半句则需借助助动词来构成疑问句。
就你的问题看，前半句用了实义动词，后半句是需要借助助动词的。第三人称单数，一般现在时，这两种情况下，助动词需要用does。
如果这句话改成“The little girl is pretty, is she?”也是对的。

收起

主句中looks是一般现在时，所以反义疑问句就要用does

那个小女孩看起来和可爱，不是吗？
does 对应的是行为动词
而IS是BE动词
look 是行为动词，所以用
