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:
Iamateacher.→Iamnotateacher.
LiLeicanswim.→LiLeicannot(can't)swim.
Wehavelearned3,000words.→Wehavenot(haven't)learned3,000words.
Hewillgotothezooifitrainstomorrow.→Hewillnot(won't)gotothezooifitrainstomorrow.
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/didnot,并把该谓语动词恢复原形.如:
Igetupatsixo'clockeveryday.→Idon'tgetupatsixo'clockeveryday.
MrWangworksinafactory.→MrWangdoesn'tworkinafactory.
XiaLinvisitedourfriendslastnight.→XiaLindidn'tvisitourfriendslastnight.
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:
Heisalwayslateforschool.→Heisneverlateforschool.
Myuncle'severbeentomanypartsofEngland.→MyunclehasneverbeentomanypartsofEngland.
(2)肯定句中含有nearly,almost,变否定句时改为hardly.如:
LinTaonearlyknowshim.→LinTaohardlyknowshim.
(3)肯定句中含有many,much,变否定句时改为few,little.如:
Manystudentsknowthemanunderthetree.→Fewstudentsknowthemanunderthetree.
Thereismuchwaterintheglass.→Thereislittlewaterintheglass.
(4)肯定句中含有both,both…and,all,变否定句时改为neither,neither…nor,none.如:
Bothofusarestudents.→Neitherofusisastudent.
IknowbothEnglishandChinese.→IknowneitherEnglishnorChinese.
Allofthemlikebananas.→Noneofthemlike(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:
Everythingisready.→Nothingisready.
Thereissomethingwrongwithmybike.→Thereisnothingwrongwithmybike.
(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:
Sheisoldenoughtogotoschool.→Sheistooyoungtogotoschool.
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:
Closethedoor.→Don'tclosethedoor.
2.肯定句是“hadbetter+动词原形”,变否定句时改为“hadbetternot+动词原形”.如:
You'dbettercometoschoolearliernexttime.→You'dbetternotcometoschoolearliernexttime.
3.以Let's或Letus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'splaywithfire.→Let'snotplaywithfire.→Don'tlet'splaywithfire.
Letmetryagain.→Letmenottryagain.→Don'tletmetryagain.
三、复合句的肯定式变否定式
1.一般将主句变为否定式.如:
Iwascookingwhenheknockedatthedoor.→Iwasnotcookingwhenheknockedatthedoor.
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:
Ithinkhewillgiveyouacall.→Idon'tthinkhewillgiveyouacall.
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:
Theteacheraskedmetospeakmoreloudly.→Theteacheraskedmenottospeakmoreloudly.
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:
Hecanreadandwrite.→Hecan'treadorwrite.
Wecanseesomeflowersinfrontofthehouse.→Wecan'tseeanyflowersinfrontofthehouse.
ThestudentsofNo2MiddleSchoolhavegoneforapicnicalready.→ThestudentsofNo2MiddleSchoolhaven'tgoneforapicnicyet.

Manystudentsknowthemanunderthetree.可不可以变成:Manystudentsdontknowthemanunderthetree.Thereismuchwaterintheglass.可不可以变成:Thereisnotanywaterintheglass.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~GoodLuck!!
