英语改否定句有多种方法和技巧，以下是具体的步骤和注意事项：
一、基本方法
在be动词（如is、am、are、was、were）后加not。例如：I am a student. 改为否定句为：I am not a student.
在情态动词（如can、should、will、must等）后加not。例如：You should go to bed early. 改为否定句为：You shouldn't go to bed early.
在没有be动词和情态动词的情况下，需在行为动词前加上助动词（如do、does、did）和not。例如：She likes apples. 改为否定句为：She doesn't like apples.
二、特殊技巧
当肯定句中含有always、usually和ever时，改否定句时应将其改为never。
肯定句中的some在否定句中应改为any，too改为either，already改为yet。
当句子中的动词为原形时，使用don't进行否定；若动词为第三人称单数形式，则使用doesn't，并将动词还原为原形。
三、注意事项
改写否定句时，应确保句子的意思和原句相反，但其他部分（如主语、宾语、状语等）保持不变。
在动词后面加not。
1、有 be 动词的句子在这些词后面加not，I am (not) a boy。
2、没有 be 动词的句子在动词前加助动词，如： don't或者do not，I （don't）like basketball。
3、如果有must、may、can这类的词，在这类词后面加not，I can （not ）walk。
一般是根据句子的不同情况进行改动。
扩展资料：
be动词的用法：
陈述句:be动词第一人称用am，第二人称用are，第三人称单数用is复数用are。助动词do一般省略，直接用动词，注意动词时态和人称变化。有时在动词前加do，表示强调，加强语气。如:Do be quiet!
疑问句:be动词直接提前，其他部分不变(由陈述句转变)。助动词do同样，由省略直接提前放置，后面动词不变，注意do的时态和人称变化。
否定句:be动词和助动词do后面加not。
否定句通常在BE动词，情态动词后加Not。例如I can play basketball就变为I can not play basketball.
一般疑问句就是把BE动词提前，其他不变。例如He is a student.就变为Is he a student?
对划线部分提问，先找疑问词替代划线部分，之后将BE动词提前。例如He is doing homework,向 doing homework划线，则变为What is he doing.可见疑问词what代替了划线部分。
