I am a student too怎么改为否定句
该句子改为否定句是:I am not a student too.(我也不是一个学生。)
英语句子改成否定句的方法:
1.如果句子中有be动词、情态动词和助动词时可以再be动词、情态动词和助动词后加not
例如:I am a teacher.→I am not a teacher.
She can help me.→She can't help me.
Yes,I do.→No,I don't.
2.如果句中谓语动词为行为动词时,要根据时态选用do的相应形式,把肯定句变为否定句。
例如:The little girl wants to go there.
→The little girl doesn't want to go there.
He did his work yesterday.→He didn't do his work yesterday.
3.如果是祈使句变否定句时,一般在句首加Don't,但Let us或Let's开头的祈使句在 Let us或 Let's后加not即可。
例如:Put them over there.→Don't put them over there.
Let us go home.→Let us not go home.
4.如果主从复合句中,主句是I think,I believe等结构,变否定句时,形式上否定主句,实际上否定从句。
例如:I think chickens can swim .我认为鸡会游泳。
→I don't think chickens can swim .我认为鸡不会游泳。
5.如果剧中有“had better +动词原形”,变否定句时为“had better not +动词原形”。
例如:You'd better go to school.→ You'd better not go to school.
6.动词不定式变否定式时,常在不定式to前加not。
例如:The teacher tells me to do it.→The teacher tells me not to do it.
7.如果句中有使役动词和感官动词(make,let,hear,see,watch等)后接省略to的不定式,此种不定式变否定句时只需在省略to的动词原形前加not。
例如:I saw her work.→I saw her not work.
I am a student too改为否定句是 I am not a student either.

We have not (haven't) learned 3 000 words.

2、原句中没有be动词,助动词或情态动词吋,要在行为动词前加助动词do,does,did与香定副词not的缩写形式

如:

I don't get up at six o'clock every day(否定句)
我没有每天6点起床。
(2)句中第一个动词是三单形式时,在其前加上 doesnt,原来的动词三单形式改为动词原形。
如:

Mr Wang doesn,'t work in a factory(否定句)
王先生不在工厂工作。
(3)句中第一个动词是过去式时,在其前加上didn't,原来的动词过去式改为动词原形。
如:
Xia Lin visited our friends last night.
林霞昨天晚上拜访了我们的朋友。
Kia lin didn t visit our friends last night.
林霞昨天晚上没有拜访我们的朋友。
3、肯定句变否定句需要变化的其他形式。
(1)当everyone(everybody).someone(somebody),something,everything等不定代词作肯定句的主语时,一般不能在其后加 not变为否定句,而要把everyone(everybody).someone(somebody)改为noone或nobody;把不定代词something,everything改为nothing等形式构成否定句。
(2)both,all 作肯定句的主语或主语的定语时,变否定句时应把both改为neither,all改为none。
(3)带有too,also的肯定句变为否定句时,应将too,also变为either,且放在句末;带有already的肯定句变为否定句时,应将already变为yet,且放在句末。
(4)含有both and的肯定句常用either nor来构成否定句。
(5)含有always,often的肯定句变为否定句时,要把always改为never,把often改为seldom.(6)含有a few,a little等的肯定句改为否定句时,将a few,a little改为few,little表示否定意义。
