小学英语常见句型转换大全:肯定句、否定句、疑问句一次学会
小学英语考试中，句型转换几乎每个年级都会遇到。
肯定句变否定句、肯定句变一般疑问句、对画线部分提问……看起来变化很多，其实只要先找到句子里的关键动词，再按照规则变化，就不会乱。
这篇整理好常见句型转换规则，家长可以直接收藏，孩子考前复习时照着练。
be动词包括：am、is、are、was、were
1. 肯定句变否定句
直接在be动词后面加 not。
例句：
I am happy.→ I am not happy.我不开心。
She is a teacher.→ She is not a teacher.她不是老师。
They are at school.→ They are not at school.他们不在学校。
2. 肯定句变一般疑问句
把be动词提到句首，句号变问号。
She is your sister.→ Is she your sister?
They are students.→ Are they students?
You are ready.→ Are you ready?
回答：
Is she your sister?Yes, she is. / No, she isn't.
Are they students?Yes, they are. / No, they aren't.
注意： 主语是I时，疑问句中通常变成you。
I am a student.→ Are you a student?
这是小学句型转换中最容易出错的部分之一。
1. 肯定句变否定句
主语是 I、you、we、they，用 don't。
I like apples.→ I don't like apples.
They play football.→ They don't play football.
主语是 he、she、it，用 doesn't。
He likes apples.→ He doesn't like apples.
She plays tennis.→ She doesn't play tennis.
重要规则
doesn't后面的动词必须用原形。
错误：He doesn't likes apples.正确：He doesn't like apples.
错误：She doesn't plays football.正确：She doesn't play football.
因为 does 已经承担了第三人称单数的变化，后面的动词要恢复原形。
2. 肯定句变一般疑问句
主语是 I、you、we、they，句首用 Do。
You like English.→ Do you like English?
They play basketball.→ Do they play basketball?
主语是 he、she、it，句首用 Does。
He likes English.→ Does he like English?
She plays basketball.→ Does she play basketball?
同样要注意：
Does he likes English? ❌Does he like English? ✅
Does she plays basketball? ❌Does she play basketball? ✅
3. 一般疑问句的回答
Do you like English?
Yes, I do.No, I don't.
Does he like English?
Yes, he does.No, he doesn't.
1. 肯定句变否定句
直接在can后面加 not。
I can swim.→ I can't swim.
She can dance.→ She can't dance.
They can play football.→ They can't play football.
2. 肯定句变一般疑问句
把 Can 提到句首。
You can swim.→ Can you swim?
He can play basketball.→ Can he play basketball?
3. 回答
Can you swim?
Yes, I can.No, I can't.
注意：
can后面一定用动词原形。
I can swim. ✅I can swims. ❌
Can she dance? ✅Can she dances? ❌
1. 肯定句变否定句
使用 didn't + 动词原形。

孩子遇到句型转换题，可以按下面5步检查：
第1步：找动词
看看句子里是be动词、实义动词、can还是过去式。
第2步：判断时态
现在还是过去？
第3步：判断主语
是I/you/we/they，还是he/she/it？
第4步：选择助动词
一般现在时：
I/you/we/they → dohe/she/it → does
一般过去时：
→ did
第5步：注意动词变化
出现 does、doesn't、did、didn't 后，后面的实义动词通常要用原形。
这是句型转换中最值得孩子反复检查的一条规则。
1. He doesn't likes apples. ❌He doesn't like apples. ✅
2. Does she plays tennis? ❌Does she play tennis? ✅
3. Did you went there? ❌Did you go there? ✅

参考答案

小学阶段的句型转换，不需要把所有规则都背得很复杂，下面这些一定要熟。
be动词变否定：am/is/are + not
一般现在时否定：don't/doesn't + 动词原形
一般现在时疑问：Do/Does + 主语 + 动词原形？
can否定：can't + 动词原形
can疑问：Can + 主语 + 动词原形？
一般过去时否定：didn't + 动词原形
一般过去时疑问：Did + 主语 + 动词原形？
最重要的一句话：
看到does、doesn't、did、didn't、can，后面的动词先想“用原形”。
掌握这条，很多句型转换题就不会再因为动词变化而丢分。
