这里我帮你找了肯定变否定的语法摘要,
一、陈述句的肯定式变否定式
1.谓语动词是系动词 be 、情态动词或助动词时,直接在这些词的后面加上否定词.如：
I am a teacher.→ I am not a teacher.
Li Lei can swim.→ Li Lei cannot （ can't ） swim.
We have learned 3,000 words.→ We have not （ haven't ） learned 3,000 words.
He will go to the zoo if it rains tomorrow.→ He will not （ won't ） go to the zoo if it rains tomorrow.
2.谓语动词是行为动词时,要根据时态选用 do 的相应形式,即 do / does / did not ,并把该谓语动词恢复原形.如：
I get up at six o'clock every day.→ I don't get up at six o'clock every day.
Mr Wang works in a factory.→ Mr Wang doesn't work in a factory.
Xia Lin visited our friends last night.→ Xia Lin didn't visit our friends last night.
3.用含有否定意义的词或词组直接取代肯定句中的某些词或词组.
（ 1 ）肯定句中含有 always 和 ever ,变否定句时改为 never .如：
He is always late for school.→ He is never late for school.
My uncle's ever been to many parts of England.→ My uncle has never been to many parts of England.
（ 2 ）肯定句中含有 nearly ,almost ,变否定句时改为 hardly .如：
Lin Tao nearly knows him.→ Lin Tao hardly knows him.
（ 3 ）肯定句中含有 many ,much,变否定句时改为 few,little .如：
Many students know the man under the tree.→ Few students know the man under the tree.
There is much water in the glass.→ There is little water in the glass.
（ 4 ）肯定句中含有 both,both … and ,all ,变否定句时改为 neither,neither … nor,none .如：
Both of us are students.→ Neither of us is a student.
I know both English and Chinese.→ I know neither English nor Chinese.
All of them like bananas.→ None of them like （ s ） bananas.
（ 5 ）肯定句中含有 every-,some- 的合成词,变否定句时常改为含有 no- 的合成词.如：
Everything is ready.→ Nothing is ready.
There is something wrong with my bike.→ There is nothing wrong with my bike.
（ 6 ）肯定句中含有“形容词＋ enough ”,变否定句时改为“ too ＋形容词的反义词”.如：
She is old enough to go to school.→ She is too young to go to school.
二、祈使句的肯定式变否定式
1.一般情况下,在句首的动词前加 Don't .如：
Close the door.→ Don't close the door.
2.肯定句是“ had better ＋动词原形”,变否定句时改为“ had better not ＋动词原形”.如：
You'd better come to school earlier next time.→ You'd better not come to school earlier next time.
3.以 Let's 或 Let us 开头的祈使句,在变否定句时常在其后加 not ；有时也可在其前加 Don't .如：
Let's play with fire.→ Let's not play with fire.→ Don't let's play with fire.
Let me try again.→ Let me not try again.→ Don't let me try again.
三、复合句的肯定式变否定式
1.一般将主句变为否定式.如：
I was cooking when he knocked at the door.→ I was not cooking when he knocked at the door.
2.在谓语动词是 think,believe,suppose,guess 等的宾语从句中,变否定句时常否定主句.如：
I think he will give you a call.→ I don't think he will give you a call.
四、肯定句变否定句应注意的其他情况
1.动词不定式变否定式时,常在不定式符号 to 前加 not .如：
The teacher asked me to speak more loudly.→ The teacher asked me not to speak more loudly.
2.既要否定谓语动词,又要变换句中的单词（ and 一般要变为 or,some 变为 any,already 变为 yet,too 变为 either ）.如：
He can read and write.→ He can't read or write.
We can see some flowers in front of the house.→ We can't see any flowers in front of the house.
The students of No 2 Middle School have gone for a picnic already.→ The students of No 2 Middle School haven't gone for a picnic yet.Many students know the man under the tree. 可不可以变成：Many students dont know the man under the tree. There is much water in the glass. 可不可以变成：There is not any water in the glass.您还可不可以多举几个例子？可以的~上面的例子已经是精华啦~掌握这些基本上任何肯定句都能变成否定重在掌握，相信老师罚抄的目的是帮助你掌握这个知识点而不是真正的惩罚~所以呢，学会上面的就ok啦~（如果必须要抄的话，可以试试找课文中的肯定句，自己把它们变成否定，既是练习也是理解记忆！）O(∩_∩)O~加油哦~Good Luck！！
