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

如题所述

They are talking about their homework.的否定句是They are not talking about their homework.

说明:are talking是现在进行时,即Be动词+现在分词。只需在be动词后面+not,即可变成否定句。又如:

肯定句:He is reading a book.

否定句:He is not reading a book.

they are talking about their homework.他们正在讨论家庭作业。这里有be动词are,直接在are后面加一个not就变成了否定句。

they are not talking about the homework他们不是正在讨论家庭作业。

They are not talking about their homework.

进行时态的否定句直接在助动词be的后面加not

they are not talking about their homework.
一般现在时:(1、现在的状态。2、经常或习惯性动作。3、主语所具备的性格和能力。4、真理。)
1、标志:often(经常),usually(通常),sometimes(有时),always(总是),never(从不),
on Sundays(在星期天), every day/month/year(每一天/月/年)
2、结构:
(1)主语+连系动词be(am/is/are)+名词/形容词/数词/介词短语/副词等做表语表状态。
(2)主语(非第三人称单数)+行为动词原形+其他 (用助动词do 帮助构成否定句、一般疑问句和特殊疑问)
(3)主语(第三人称单数)+行为动词的第三人称单数+其他(用助动词does 帮助构成否定句、一般疑问句和特殊疑问句)
行为动词第三人称单数加-s的形式
1.- s
2. 辅音+y: study-studies
3.以s,x,ch,sh结尾watch-watches  teach-teaches
4特殊have-has do-does go-goes
