2013年PEP五年级下专题训练—句型转换
一、肯定句、否定句、一般疑问句和特殊疑问句定义 1．肯定句：表示肯定的意思, 即不含有否定词“不”。 比如：我是一个学生 I am a student. 他去上学 He goes to school. 2．否定句：表示否定的意思。
比如：我不是一个男孩。 I am not a boy
他不去上学 He does not go to school.
3. 一般疑问句：回答为“是yes”或者“否no”的问句。 比如：你是一个学生吗？ Are you a student? 你喜欢英语吗？ Do you like English?
4. 特殊疑问句：回答不是“是yes”或者“否no”的问句，根据提问内容具体回答。 比如：现在几点了？ What’s the time?
哪一支笔是你的？ Which is your pen?
二、句型变化规则： A.肯定句变否定句
1、在be动词后加not。如：is not ， are not ， am not， was not， were not； eg: I am a teacher. → I am not a teacher. 2、在can，等后加not。如：cannot
eg:Li Lei can swim. → Li Lei can not （ can't ） swim. 1. I am listening to music.
2. Mike is a student.
3. Sarah can clean the classroom.
4. They are in the zoo.
5. There are some flowers in the vase.
6.This is my sister.
7.We are sweeping the floor.
3、 上述都没有的，在动词前加助动词否定形式do not, does not. (don’t/doesn’t)
eg:Mr Wang works in a factory. → Mr Wang doesn't work in a factory. 1. We need some masks.
2. They like making the puppet.
3. Su Hai and Su Yang live in a new house.
4.I put a book on my head.
5. They sing “In the classroom”together.
6.We play basketball on Sundays.
7. Tom likes listening to music
B.肯定句变一般疑问句
如何将一个肯定的陈述句改为一般疑问句：
1、把be动词放在句首，剩下的照抄，（some 改成any，my改成your等）句点改成问号。
We're watching TV． → Are you watching TV﹖
2、把can等情态动词放到句首，剩下的照抄，（some 改成any，my改成your等）句点改成问号。
The children may come with us． → May the children come with us﹖ 1. I am listening to music.
2. Mike is a student.
3. Sarah can clean the classroom.
4. They are in the zoo.
5. There are some flowers in the vase.
6.This is my sister.
7.We are sweeping the floor.
3、上述都没有的，在句首请助动词Do/Does帮忙，剩下的照抄，（some 改成any，my改成your等）句点改成问号。
eg:She wants to go to the park → Does she want to go to the park﹖ 1. We need some masks.
2. They like making the puppet.
3. Su Hai and Su Yang live in a new house.
4.I put a book on my head.
5. They sing “In the classroom”together.
6.We play basketball on Sundays.
7. Tom likes listening to music
C.肯定句变特殊疑问句
肯定句变特殊疑问句（就划线部分提问）：分3步骤 第一步：先变一般疑问句
第二步：找合适的特殊疑问词代替划线部分
第三步：特殊疑问词提前放到句首，并大写，其余按顺序照抄，省略划线部分。 第四步：句点改为问号。 注意：
1.一定先变一般疑问句。但是，如果问的是主语或主语的定语时，语序不变， 为\特殊疑问词(+主语)+陈述句\。
如：Li ming 's not here today. Who's not here today? 今天谁没来？ 2.划线部分不能在特殊疑问句中出现。 3.特殊疑问词大总结： 疑问词 What time Who 意思 什么时间 谁 用法 问具体时间，如几点钟 问人
Whose Where What What colour How old How How many How much Which when why 谁的 在哪里 什么 什么颜色 多大年纪 怎样 多少数量（可数名词） 多少钱；多少数量（不可数名词） 哪个 什么时候 为什么 问主人 问地点 问东西、事物 问颜色 问年纪 问方式、程度、状态 问数量 问多少钱或数量（不可数） 问人和物 问时间 问原因 特殊疑问词选择专题练习：
