怎么做英语一般疑问句和否定句

姐姐 帮我下吧 我明天要考试瓦

假如：太阳是从东边出来的。the sun comes out from the east.那就用“what, where, when, why, how, if”这些开始where does the sun come out at?否定句就用：“is not, isn't, doesn't, wasn't”之类the sun doesn't come out from the east.

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?

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.
