专题:把一定句改成否定句
把一定句改成否定句分以下状况:
1、句中有be动词的,在be动词后加not;
2、句中有神态动词的(can,should,must,would),在神态动词后边加not;
3、句中没有be动词和神态动词的,在动词前加don’t或doesn’;t
①句中动词为原形的,加don’t.如:Ilikeapples.Idon’liketapples.
②句中动词为三单式的,加doesn’t,并将三单式的动词还原成原形。
如:Helikesapples.Hedoesn’tlikeapples.
③时态为过去时的,要加didn’t并且动词过去式要改为原形,
例:Iwenttoschoolyesterday.→Ididn’tgotoschoolyeaterday.
4.一定句中的some在否定句中应改为any
如:Therearesomestudentsintheclassroom.Therearenotany
studentsintheclassroom.
