怎么做英语一般疑问句和否定句

这个太简单了。

假入用现在进行时。Is
she
swimming?

用否定回答就是，No,she
isn't.

就是把疑问句的be动词和主语倒过来加not.懂了么？

如果是肯定回答，就是，yes,
she
is.

也是be动词和主语倒过来，但因为是肯定，所以，不加not.

一般疑问句就是1)将系动词提前，其余各个成分直接抄下来就行了！

例如：You
are
kind.

变成Are
you
kind?

2)实义动词用do的适当形式来提前

例如：He
did
his
homework
yesterday.

变成Did
he
do
his
homework
yesterday?
