Question

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

Answer 1

1.否定句是表示否定的句子。必须有否定词。英语中否定句通常借助否定词no,not，never，nothing，nobody，none，etc，半否定词hardly scarcely，few，little，etc．以及否定词缀构成。
一般说来，all/both/every-+ not =部分否定；none/neither/no-=完全否定；any/either/ any-+not =完全否定。
every-，指那些以 every 开头的复合词，如 - everybody，everything，everywhere，etc.
no-，指那些以 no 开头的复合词，如：nobody，nothing，nowhere，etc.
any-，指那些以 any 开头的复合词，如：anyone，anything，anywhere，anybody，etc.
例如：
All that glitters is not gold.
【译文】发光的东西除了金子，还有别的东西。
2.根据上述分类，建议将They are talking about their homework.改写成三种否定句。
（1）They never talk about their homework.全否定。
（2）They are not talking about their homework.全否定。
（3）They are hardly talking about their homework.半否定。

Answer 2

分析：肯定句变为否定句，需要在be动词后加not ,所以这句话改为否定句为：They are not talking about their homework.

Answer 3

They aren't talking about their homework.
句子的开头首字母要大写
考点，含有be动词的陈述句变否定句
方法，直接在be动词后面加not
这句话的翻译为，
他们没有正在谈论他们的家庭作业。

Answer 4

回答和翻译如下 :
They are not talking about their homework .
他们不能讨论他们的回家作业 。
( 已经改为否定句形式 ，请麻烦把中英语的句子记熟 ，并且 ，千万不要忘记把英语句子的总复习环节做好 。)

Answer 5

They are talking about their homework.他们在讨论他们的作业。否定句在be动词后加not，写作are not或者aren't，否定句完整形式为They are not （ aren't）talking about their homework.
