They do not have time to study and do housework.

they do not have time to study

too前面的they do not have time to study and do housework, 是对前面那句kids these days already have enough stress from school的补充，表示，孩子们在学校已经有足够大的压力，而且他们也没有时间学习和做家务。too不是针对do housework而言，而是对整句话而言，因此没有问题。

They do not have time to study and do housework , too.这句话对不对?

不对的！ 你理解的很好。需把and--or， too---either. 祝你进步！开心每一天！

They do not have time to study and do housework,too.语法

either or 是应用在这个或那个， 较合适的是 neither nor 如 they neither have time to study nor do housework

初二英语！这个句子：They do not have time to study and do h

你可能搞混了。公式应该是sb. have time to do sth. 还有一个是spend time doing sth. 这个很容易搞混，当年我也错了一大片。

They don't have time to study and do housework,t

这个and并列的是动词不定式符号to之后的study和do housework,与之前的not无关,too也是一样的道理~
