肯定句改为否定句 在英语过去式的句子中，除了疑问句，否定句和肯定句中的动词是不是全都要变成过去式？

在英语过去式的句子中，除了疑问句，否定句和肯定句中的动词是不是全都要变成过去式？  

在英语过去式的句子中，除了疑问句，否定句和肯定句中的动词是不是全都要变成过去式？

疑问句：例：Did you do sth？
否定句：例：I didn't do sth。
肯定句就要变成过去式了：例：I had lunch at my home yesterday。
所以，只有肯定句的动词是要变过去式的，其它的都不要。
望采纳！

过去式的肯定句,否定句,疑问句的结构

1. be- was- were, 否定句： was not= wasn't, were not= weren't,一般疑问句把was, were提前到句首
如： I was at home yesterday.
I wasn't at home yesterday.
Were you at home yesterday?
Where were you yesterday?
2 行为动词： 主语+ 过去式
主语+ didn'g + 动词原形 （ 否定句）
Did+ 主语 + 动词原形 （ 一般疑问句）
如： I played football yesterday.
I didn't play football yesterday.
Did you play football yesterday.
What did you do yesterday?
3 情态动词：如： can
主语 + could +动词原形
主语+ couldn't + 动词原形
Could + 主语 + 动词原形
如： I could swim when I was ten.
I couldn't swim when I was ten.
Could you swim when you were ten?
what could you do when you were ten?
关于一般过去时态，我就想到这么多，希望对你有所帮助

写出实意动词（行为动词）一般过去式的肯定句，否定句，一般疑问句，特殊疑问句的结构式

过去式：动词加ed
肯定句：主语+动词过去式 I worked there yesterday.
疑问句：did+主语+动词原形 Did you work there yesterday?
否定句：did+not+动词原形 I did not work there yesterday.
特殊疑问句：wh疑问词+did+主语+动词原形 What did you do yesterday?

在疑问句和否定句中动词的过去式和ing型时是否要变回原型？

举个例子吧：
1，过去式肯定句：He jumped onto a box.
改成疑问句：Did he jump onto a box? 这里，过去式变成了原型（过去式跑到前面的助动词那里了）
改成否定句：He didn't jump onto a box. 同疑问句
2，ing肯定句：He is jumping onto a box.
改成疑问句：Is he jumping onto a box? 这里，仅仅把be动词移动位置，ing不变。
改成否定句：He is not jumping onto a box. 同样，仅仅是把be动词做否定，ing不变。

以make为例各造三个一般现在时，一般过去式的句子（肯定句，疑问句，否定句）急～～～！

He makes cakes at home .他在家做蛋糕。
Does he make cakes at home ？他在家做蛋糕吗？
He doesn't make cakes at home 他在家不做蛋糕。
He made me work for him .他让我为他干活。
Did he make you work for him ？他让你为他干活吗？
He didn‘t made me work for him ？他没有让我为他干活。
望楼主满意我的回答，如有疑问，线上商榷

有be动词过去式的句子怎么改否定句

给你一些例句
i was a teacher.
i was not a teacher.
i worked here ten years ago.
i did not work here ten years ago

疑问句中，过去式要变原形嘛？

在助动词did后，需要变回原形。但作谓语的情况下，就不需要变化。
比如：Who went to Beijing last week ?

否定句中的动词要用过去式吗?

可以。
