一
Don't let the children stay up too late on weekends,will you?
Don't let the children eat a lot of sweets,shall we?
这组句子后面的附近疑问词为什么会不同?语法书说不是只有let's的时候才用shall 还有这里为什么不能当做祈使句来处理呢（就是祈使句的否定形式啊,就该填will you了）?
二
She had her hair cut the day before yesterday,didn't she?
You had your watch repaired yesterday,hadn't you?
这2个句子,看不出来结构上有什么不同.为什么它们的附近疑问部分,会不同呢?

一 will you 是单词“你”不要让孩子周末玩到很晚.shall we,强调,“我们”不要让孩子吃很多糖果.
但大部分是情况,确实是LET's 才有shall we,口语使用情况比较随意 .第二句用will you也可以.
二
第一句过去式,had 为have 的过去试,是动作,反问为be动词过去式否定
第二句 had当过去分词型,变成had的否定
