在几年的英语教学中，我总结了一些英语句子教学的小窍门，现简单归纳如下： 一、肯定句改否定句的方法 ：
1、 在be动词后加not。如：is not ， are not ， am not， was not， were not； 2、 在can，should， will等后加not。如：cannot， should not， 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.
→ This isn’t Tom’s bag. 答题方法是；否定词not在be后边。 二、肯定句改一般疑问句的方法：
1、 把be动词放在句首，剩下的照抄，（some 改成any，I改成you，my改成your，）句点改成问号。
2、 把can，shall， will等放到句首，剩下的照抄，（some 改成any，I改成you，my改成your，）句点改成问号。 3、 上述都没有的，在句首请助动词Do/Does/Did帮忙，剩下的照抄，（some 改成any，I改成you，my改成your，）句点改成问号。
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，肯定回答用yes,否定回答用no。 语句顺序为：Yes + 主语 + am /is/ are/was/were.|can.|do/does/did|; No + 主语+ am not/ isn’t/ aren’t/wasn't/weren't.|can't.|don't/doesn't/didn't|.。如： —Are you an English teacher?→Yes, I am. /No, I am not. —Is that a bird? →Yes, it is./ No, it isn’t. 三、对划线部分提问
“就划线部分提问”是小学阶段英语学习的难点，但是一旦掌握了规律，就变得容易多了。 小学英语对划线部分提问之答题口诀 ：
一代：用正确的疑问词代替划线部分。 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。)
★特殊疑问词的确定要根据划线内容而定,在小学阶段常出现的有以下几种： 1.划线部分是“事或物”，特殊疑问词用what 如: This is a book. ---What is this?
I often play football on Saturdays .
---What do you often do on Saturdays ? 2.划线部分是“人”，特殊疑问词用who 如:He is my brother. ---Who is he ?
1
３、划线部分是“地点”，特殊疑问词用where 如:The box is on the desk.---Where is the box ?
４、划线部分是“时间”，特殊疑问词用what time或when 如:It's seven twenty . ---What time is it ?
I usually get up at six . --- When do you usually get up? ５、划线部分是“年龄”，特殊疑问词用how old 如:I am twelve . ---How old are you?
My father is thirty-three . ---How old is your father ? ６、划线部分是“职业”，特殊疑问词用what 如:Mike is a worker. ---What is Mike ?
７、划线部分是“颜色”，特殊疑问词用what colour 如: My hat is blue . ---What colour is your hat？
8. 划线部分是“数量”，特殊疑问词用how many或how much 如:I can see five kites .---How many kites can you see ?
There is some milk in the glass. ---How much milk is there in the glass ? ９、划线部分是“多少钱”，特殊疑问词用how much 如:This pen is nine yuan . ---How much is this pen ?
１０、划线部分是“形容词性物主代词或名词性物主代词”，特殊疑问词用whose 如:That is my book . ---Whose book is that ?
The bag is yours. ---Whose is the bag ?
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； 4．问“原因”，用why； 5．问“身体状况”，用how； 6．问“方式”，用how； 7．问“年龄”，用how old； 8．问“多少”，用how many； 9．问\"价钱”用how much； 10．问“哪一个”，用which ； 11．问“什么”，用what； 12．问“职业”，用what； 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。如： I’m Peter. → My name is Peter. Tom is tall. →Tom isn’t short. I‘m fine. →I'm all right.
2
我们现在学过的大多数句型，在一般情况下（就是不排除有特殊情况）都可以用简单的公式来记忆。 1.肯定句变否定句 1) 主语+be动词+….
*I am a teacher.→ I am not a teacher. He is a doctor. → He is not a doctor. They are students. →They’re not students.
2) 主语+do动词的不同形式+….
I play computer games everyday. →I don’t play computer games everyday.
He plays computer games everyday. →He doesn’t play computer games everyday We played computer games yesterday.→ We didn’t play computer games everyday
2肯定句变一般疑问句
1）问：be动词+主语+…?
答：Yes, 主语+be动词。/No, 主语+be动词+not. I am a teacher. →Are you a teacher? Yes, I am. No, I am not.
He is a doctor.→ Is he a doctor? Yes, he is. No, he is not.
They are students. →Are they students? Yes, they are. No, they are not.
2) 问：助动词+主语+do动词的原形+…?
答：Yes, 主语+助动词。/No, 主语+助动词+not. I play computer games everyday.
→Do you play computer games everyday? Yes, I do. No, I don’t. He plays computer games everyday.
→Does he play computer games everyday? Yes, he does. No, he doesn’t. We played computer games yesterday.
→Did you play computer games yesterday? Yes, we did. No, we didn’t.
