Question

they are talking about their homework(改为否定句)？

Answer 1

这句话是现在进行时的肯定句，变为否定句，有be动词 ，直接在be动词are后加not 。即：They are not talking about their homework.
也可以缩写为：They aren’t talking about thei homework.

Answer 2

They aren’t talking about their homework.变否定句就是在be 动词后加not
其他情况 如果是实义动词 就借助于don’t doesn’t didn’t
如果是是情态动词 直接在后边加not

Answer 3

They are talking about their homework．改为否定句 是： They are not talking about their homework．
