英语的一般疑问句和否定句怎样改
改写否定句和一般疑问句的规则如下：
改写否定句：
句子中有be动词的，在be动词后面加not，be包括am，is，are，was，were
He is not watching TV now. 现在他没在看电视。
I am not good at maths. 我数学学得不好。
句子中有实义动词的，要先加助动词（do或have的适当形式），再加not
My father doesn't work on Sundays. 我爸爸周日不工作。
He didn't like reading before. 他以前不喜欢读书。
I haven't had my lunch. 我还没吃完饭。
She hasn't passed the exam. 她还没通过考试。
句子中有情态动词的，在情态动词后面加not
My pen pal can't speak English. 我的笔友不会说英语。
She may not come tonight. 今晚她不会来了。
You needn't worry about her. 你不必担心她。
You shouldn't tell him the truth. 你不应该告诉他真相。
由think，believe，except等词引导的宾语从句，并且主语是第一人称时，要将主句变成否定句，即“否定前移”。翻译时，要对从句进行否定。
I don't think he is right. 我认为他不对。
We don't believe they will lose the match. 我们相信他们不会输掉比赛。
改写一般疑问句：
句子中有be动词的，把be动词提前，其他成分照抄，句末变问号
Is he a friend of yours？他是你的朋友吗？
Was it very cold yesterday？ 昨天很冷吗？
句子中有实义动词的，要使用助动词开头，句中的实义动词变回原形，其他成分照抄，句末变问号
She lives in Beijing. ---- Does she live in Beijing? 她住在北京吗？
He ran last nigh. ---- Did he run last night？昨晚他跑步了吗？
We have been to Paris. ---- Have you been to Paris？你们去过巴黎吗？
句中有情态动词的，把情态动词提前，其他成分照抄，句末变问号
I can spell many words. ---- Can you spell many words?你能拼写很多单词吗？
He must stay at home. ---- Must he stay at home?他必须待在家里吗？
如句子里是be动词：am,is,are,was,were
就在这些词后加：not
例句：He
is
Tom.
He
is
not
Tom.
如句子里是动词：like,eat
就在这些词前加：don't,doesn't,didn't

like
dogs.
I
don't
like
dogs.

就在这些词后加：not

can
watch
TV
now.
Can

am
a
girl.--Am
I
a
girl?---I

not

具体的就是：找出be
动词，要改为疑问句是吧，把be动词放在主语前就行了。否定句就在后面加个not就行了。
又如I
go
to
school.---Do
you
go
to
shool.---I
do
not
to
school.也就是说，当动词是实义动词时，就用助动词do,does,当主语是第三人称单数时就用does.
此外，还有情态动词，can,may,could,should,must,---找出来，和be
动词的改法一样。
把IS、Im.are.（必动词）提前！没有必动词、情态动词的，把Do提前！有can（情态动词）把情态动词提前！
否定：
把IS、Im.are.（必动词）后加n't！没有必动词、情态动词的，Do后加n't
有can（情态动词）在后加n't！
