I am a teacher. ---->I am not a teacher.我是一个老师。
---->我不是老师。
原句中含有情态动词 (can, shall, will, may, should, would, might, had better 等) 。
Li Lei can swim.---->Li Lei cannot/can't swim.李雷会游泳。
---->李雷不会游泳。
He will go to the zoo if it rains tomorrow.---->He will not/won't go to the zoo if it rains tomorrow.如果明天下雨，他将去动物园。
---->如果明天下雨，他就不去动物园了。
原句中含有助动词（have, has, had）。
We have learned 3,000 words. ---->We have not/haven't learned 3,000 words.我们已经学会了3000个单词。
---->我们还没有学会3000个单词。

二、原句中没有be动词，助动词或情态动词时，要在行为动词前加助动词 (do, does, did) 与否定副词 not 的缩写形式。
句中第一个动词是原形时，在其前加上don’t。
I get up at six o'clock every day.---->I don't get up at six o'clock every day.我每天六点起床。
英语肯定句改否定句
1、You can use this dictionary.（改为否定句）You cannot（can’t） use this dictionary.2、There is some wonderful news in today’s paper.（改为否定句）There are any wonderful news in today’s paper.3、They play football on the playground.（改为一般疑问句，并作肯定回答）will not；3、上述都没有的，在动词前加助动词否定形式don’t/doesn’t/didn’t。
4、 some 改成any。
如： I am a girl. → I am not a girl.You are a student. →You are not a student.→You aren’t a student.This is Tom’s bag, → This is not Tom’s bag.注意：句首的第一个字母要大写，句尾标点应为“？”。
如：I am in Class 6. →Are you in Class 6?You are from America. →Are you from??America?It is an orange. →Is it an orange?答题方法是：要想提问，be提前，句末“？”别忘了。
4、就一般疑问句回答一般疑问句有两种回答，即：肯定回答和否定回答。
其中，肯定二移：把疑问词移至句首三倒：颠倒主谓语，但对主语或其定语提问时除外（some 改成any，I改成you，my改成your），四抄：照抄句子剩余部分。
☆总结关键就是：“特殊疑问词+一般疑问句”(即：先根据划线部分找到特殊疑问词；再把没划线的部分变成一般疑问句的语序。
)４、划线部分是“时间”，特殊疑问词用what time或when５、划线部分是“年龄”，特殊疑问词用how old６、划线部分是“职业”，特殊疑问词用whatthat ?以下口诀要牢记：1．问“谁”用who；2．问“谁的”，用whose；3．问“地点哪里”，用where；13．问“颜色”，用what colour；14．问“星期”，用what day；15．问什么学科，用what subject；16．问“什么时候”，用when;17.问几点用What’s the time?或 What time is it?四、同义句型转换同义句型转换，是把意思相同或相近的句子用不同的词汇、短语及句型表示出来。

四年级英语肯定句改否定句练习题50题(带答案)1. My mother has a red car.A. My mother has not a red carB. My mother doesn't have a red car答案解析：B。
在将肯定句改为否定句时，如果句子中有实义动词（这里是has表示“有”），在一般现在时中，主语是第三人称单数时，要借助助动词doesn't，然后动词还原为原形。
