肯定句怎么改否定句英语
把肯定句改成否定句分差键枣亮闷以下情况：
1、句中有be动词的，在be动词后加not；
2，句中有情态动词的（can ,should，must ，would），在情态动词后面加not；
3.句中没有be动词和情态动词的，在动词前加don’t或doesn’t ；
① 句中动词为原形的，加don’t .如： I like apples. I don’t like apples.
②句中动词为三单式的，加doesn’t，并将虚拆三单式的动词还原成原形。
如：He likes apples.He doesn’t like apples.
4、肯定句中的some在否定句中应改为any
如：There are some students in the classroom.There are not any students in the classroom.
Tom’s brother is walking in the park.2. They can play football after school.
He likes the violin.
Have some bread, Tom.5.We like the mask.6.Please open your books.
7.He has some books.把陈述句改成一般疑问句，分以下情况：
1．句中有be动词的（am, is, are, was, were），将be动词移到句子开头，将句号改为问号，其他照抄。
英语肯定句变一般疑问句口诀
1.在一般现在时和一般过去时中,1)在be后加not.
He is here.否定：He isn't here They were very happy.否定：They weren't very happy
如动词是配搜正其它的实意动词：
2)如是动词原形则在前加助动词do 再加not；
They do sports every day.(do在这里是“做”的意思,是实意动词,不能直接加not否定)
否定：They don't do sports every day.
3）动词是第三人称单数则在前加助动词does 再加not； ,且单三还原成原形
He gets up at six.否定：He doesn't get up at six
4)动词是过去式,则在前加助动词did再加not；
We visited the old man yesterday.否定：We didn't visit the old man yesterday.
2.如果谓语动词是情态动词,则在情态动词后加not.情态动词也是一种助动词
We can dance very well.否定：We can't dance very well
3.如果谓语动词是其它时态,则在第一个助动词后加not
They are working hard.(be dong 中的be帮助构成了时态,是助动词)
否定：They are not working hard.
He has finished his homework.(have done 中的have帮助构成漏辩了时态,也培悔是助动词)
否定：He has not finished his homework.
4.使用no,hardly,seldom,never,nobody,few,little 等否定词
Nobody is in the room.=There is not anybody in the room.
变否定句口诀三步
1.主系表结构的句子
I
am
a
teacher.
-----
I
am
not
a
teacher.
He
is
in
Beijing.-----
He
is
not
in
Beijing.
We
are
classmates.-----
We
are
not
classmates.
It
was
cold
yesterday.-----
It
was
not
cold
yesterday.
这些句子中都有系词，am，is，are，was，were，只要在系词后面+not
，就变成否定句了。
2.主谓宾的句子
He
runs
fast.-----
He
doesn't
run
fast.
主语是仿禅三单人称，do也要用三单形式does
They
learn
from
me.------
They
don't
learn
from
me.
We
went
to
school
by
bike
.-----
We
didn't
go
to
school
by
bike.
谓语动词是过去式，do也要变过去式did
这些句子中都有谓语核大颤动词，只要在主语后面+do的适当形式+not
就行了。
3.句改败中有助动词或情态动词的
I
will
get
up
earlier
tomorrow.-----
I
will
not
get
up
earlier
tomorrow.
She
can
dance
well.-----
She
can't
dance
well.
He
has
gone
abroad.------
He
has
not
gone
abroad.
只需要在助动词或情态动词后面直接+not
，就可以变否定句了。
