and 变成or。
Eg .My family will go to Beijing and Qingdao next Sunday . (改为否定句)-My family will not go to Beijing or Qingdao next Sunday.They can run very fast. (改为否定句)-They can’t run very fast.3.Eg.谓语动词是行为动词而又没有助动词或情态动词时，必须在谓语动词前加助动词，一般现在时加助动词do ，第三人称单数加does，一般过去时加did，再和not构成否定结构。

陈述句改成双重否定句的方法和步骤
陈述句改成双重否定句的方法和步骤在我们的语文学习中，陈述句改成双重否定句是一个重要的知识点。
掌握这一技巧不仅能够丰富我们的语言表达，还能让我们更准确、更生动地传达自己的意思。
那么，如何将陈述句顺利地改成双重否定句呢？下面就为大家详细介绍陈述句改成双重否定句的方法和步骤。
首先，我们要明白什么是陈述句和双重否定句。
陈述句是用来陈述一个事实或者表达一个观点的句子，语气比较直接和平稳。
例如：“他今天去上学了。
” 而双重否定句则是用两个否定词来表达肯定的意思，语气比陈述句更加强烈。
比如：“他今天不可能没去上学。
”接下来，我们来看看将陈述句改成双重否定句的方法。
第一种方法是在陈述句中加上两个否定词，常见的否定词有“不得不”“不能不”“非……不可”“没有……不”“不会不”等等。
比如，把“我喜欢你”这个陈述句改成双重否定句，可以这样改：“我不能不喜欢你。
”再比如，“他会来参加聚会”，改成双重否定句就是“他不会不来参加聚会”。
第二种方法是在陈述句中加入“无不”“无非”“没有一个不”等词。
例如，“大家都很开心”可以改成“大家无不开心”；“这道题很简单”可以改成“这道题无非很简单”；“我们班的同学都很优秀”可以改成“我们班没有一个同学不优秀”。
在进行陈述句改双重否定句的过程中，需要遵循一定的步骤。
第一步，认真分析原陈述句的意思，确定要表达的肯定的核心内容。
这是非常关键的一步，只有明确了原句的意思，才能保证改后的双重否定句意思不变。
第二步，根据原句的意思，选择合适的否定词。
比如，如果原句表达的是一种主观的意愿或态度，通常可以用“不得不”“不能不”；如果原句强调的是普遍的情况或客观的事实，可能更适合用“无不”“没有一个不”等。
第三步，把选择好的否定词加入到原陈述句中，注意要保证句子通顺、合理。
同时，还要检查修改后的句子是否准确地表达了原句的意思，是否存在语法错误。
下面通过一些具体的例子来进一步说明。
例1：“他是一个好学生。
陈述句变否定句
二. 句子中有can will时，在其后加not。 例：He can swim. He can not swim. I will go to the park. I will not go to the park. 练习： （1）Tiger can run fast. （2）They will make a snowman. （3）Amy will take a dancing class. （4）She can go ice-skating. （5）Aunt will cook dinner.
三. 句子中无am is are can will。 1. 动词为原形时，在动词前加don’t。 例：I go to school by bike. I don’t go to school by bike. 练习： （1）They eat lunch at school. （2）I have to do my homework. （3）Boys play football at noon. （4）I want to send it today. （5）Three pandas eat bamboos.
2. 动词为单三形式时，在动词前加 doesn’t , 动词单三形式变原形。 例：He eats breakfastห้องสมุดไป่ตู้at home. He doesn’t eat breakfast at home. Mike goes to bookstore by bus. Mike doesn’t go to school by bus. 练习：（1）She wants to eat noodles. （2）Mr Zhang has to wash clothes. （3）Jack makes mooncakes for me. （4）John wears a life jacket. （5）The elephant drinks water .
陈述句改为一般疑问句或否定句
一、陈述句改为一般疑问句：1.当句子中含有be动词(am is are was were)或情态动词(can,could,may,might,will,would,must,need,shall,should等）或在完成时态中(has/have/had+过去分词)时，把这些助动词提到句首。
如：①He is a docter.-----Is he a docter? ②They were in the house yesterday.----Were they in……?③Tom can swim.----Can Tom swim? ④He has been to the park.----Has he been to the park? 另外，为符合实际习惯I am/We are..…------Are you…? I was/We were…-----Were you….?I /We can…-----Can you…..? I /We have +过去分词…..------Have you…….?2.当句中含有实义动词时，也就是句子不含上面所提到那些助动词时，必须在句首加DO/Does/Did,具体情况分以下三方面：㈠当句子中含有动词原型时，在句子前加Do, 其中，I+动词。
------Do you…?如：①I like music.---Do you like music? ②They work here.----Do they work here?㈡当句子中含有的动词加S或ES时，即句子是一般现在时，且主语为第三人称单数时，在句子前加Does.如：①He likes music.------Does he like music?②Tom comes from China.-----Does Tom come from China?（注意在此情况下，应把疑问句中的动词变原型。
）㈢当句子中的动词为过去式，在句子前加Did再把动词变原型。
