Helen likes taking photos,too.Right?No,she doesn't .为什么用doesn't 回答
问句里没有助动词,为什么后面要用助动词回答。

Helen likes taking photos,too.Right?No,she doesn't .为什么用doesn't 回答问句里没有助动词,为什么后面要用助动词回答。
—Helen likes taking photos,too.Right?
—No,she doesn't .
通常,肯定句不需要在实意动词前加“do”,当然也有例外,那就是强调句中需要加上
如:Helen DOES like taking photos.
而否定句中要加上助动词.
所以回答中为:she doesn't.
其实回答为省略,完整为:she doesn't like taking photo.因与上句重复,所以即使省略意思任然很清晰.

Helen likes taking photos,too.这句的谓语是likes,行为动词。只要是行为动词,对应的一般疑问句都用“助动词+动词”提问,而这里主语是人名,助动词要用第三人称单数does。还有什么不明白的地方吗?

No,跟doesn't 是固定搭配
半疑问句相当于是“Does helen like ……?”
