提出一个观点或表达自己心情的句子。特点：句末都是句号，用降调读！肯定句变否定句的方法1.含“be动词和情态动词”型，直接在be动词或情态动词后加not,其它照抄不变。be动词包括：am,is,are,was,were.常见的情态动词有：can,could,would,will,may等等。例句：Iamastudent.→

Iamnotastudent.→→Heisaboy.Heisnot/isn'taboy.IcanspeakEnglish.Icannot/can'tspeakEnglish.肯定句变否定句的方法2.含“实意动词”型，转换否定句时，记住五个字“一加一还原”的原则。“一加”即在实意动词前加助动词的否定don't,doesn't或didn't。“一还原”即把句中的实意动词变回原形。注意：在一般现在时中，当主语是第一、二人称或复数时，加don't来否定；当主语是第三人称或单数时，加doesn't来否定；在一般过去时中，一律用didn't来否定。例句：Ilikeapples.→→→Idon't

likeapples.Helikesapples.Hedoesn'tlikeapples.Sheworkedlastnight.Shedidn't

isnot=isn't,arenot=
