他们想要一些豌豆的英语句型怎么改成否定句
Theywantsomepeas改为否定是:Theydon'twantsomepeas。
肯定句变否定句变法规则:
一、有be动词(am、is、are)和情态动词(can、could、may、must、shoud、will、would等)时,直接在be动词和情态动词后面加not,some变为any,and变为or,too变为either,其他的照抄。
例如:
①、Iamastudent._Iamnotastudent.
②、Amyisagoodgirl._Amyisnotagoodgirl.
③、Theseflowersareverybeautiful._Theseflowersarenotverybeautiful.
④、Icanswim._Ican't(cannot)swim.
⑤、Therearesomebooksonthetable._Therearenotanybooksonthetable.
⑥、Jackisadoctor,too._Jackisnotadoctor,either.
⑦、Iwasastudenttenyearsago._Iwasnotastudenttenyearsago.
注:⑴、some、and用于肯定句中,any、or用于否定句和疑问句中。
⑵、was是is和are的过去式,were是are的过去式。
二、没有be动词(am、is、are)和情态动词(can、could、may、must、shoud、will、would等)时,在动词前面加don't、doesn't、didn't,动词恢复成原型,some变为any,and变为or,too变为either,其他的照抄。
例如:
①、Ilikemath._Idon'tlikemath.
②、Jacklikesmath,too._Jackdoesn'tlikemath,either.
③、Theylikebananasandapples._Theydon'tlikebananasorapples.
④、Lilygetsupatsixeverymorning._Lilydoesn'tgetupatsixeverymorning.
⑤、Hisfatherlikesplayingfootball._Hisfatherdoesn'tlikeplayingfootball.
⑥、Iwentfishingyesterday._ldidn'tgofishingyesterday.
注:⑴、当句子是一般过去时态时,在动词前加didn't,动词恢复成原型。
⑵、当句子是一般现在时态时,主语是第三人称单数时,在动词前加doesn't,动词恢复成原型;主语不是第三人称单数时,在动词前加don't。
