第五课时句型的转换
一、类型
1.改否定句
2.改一般疑问句
3.改特殊疑问句（即对划线部分提问）
4.改同义句
5.单复数句转换
1、改否定句
1）、加，找有没有be动词或情态动词
有，直接在be动词或情态动词后加not
没有，在动词前加助动词don’t=do not 或者doesn’t= does not，并且如果动词是第三人称单数要还原为原型
2）、改，some→any，and→or（其他都不发生改变）
注意：否定的缩写形式，如：is not=isn't， are not= aren't can not = can't，am not 无缩写
2、改一般疑问句（一提二改三问号）
1）提，找是否有be动词或情态动词
有，直接将be动词或情态动词提至句首
没有，在句首添加助动词do/does，并且如果动词是第三人称单数要还
原为原型
2）改，some→any，and→or，第一和第二人称要进行互换
第一人称：i，we（我，我们）第二人称：you, you（你，你们）
3）句尾改问号
3.改特殊疑问句（即对划线部分提问）
特殊疑问句的构成：特殊疑问词+一般疑问句
特殊疑问词有哪些呢?
对某件事，某个东西，what 对原因，why
对某种方式，问路，感受等，how（怎么了）对地点，where
对时间，when，what time 对数量，how many
对人，who 对某人的，谁谁的，whose
1）定，确定特殊疑问词
2）看，看原句是否有be动词或情态动词
有，特殊疑问词后接原句里的be动词或情态动词
没有，特殊疑问句词后接助动词do/does，同时原句三单要改为原形3）改，some→any，and→or，第一和第二人称进行互换
4）补，如果划线部分有动词，要将其改为do的适当形式
如：I often go to the park at weekends.
1）定，对某事提问，定what
2）看，原句无be/情态动词，所以用do, what do
3）改（抄），i→you, What do you often at weekends？
4）补，因为划线部分有动词go，补上do，What do you often do at weekends
特殊注意：
1. 当划线部分为在句首的某人，用who提问时，不遵循上述规律，who后原句有情态动词用情态动词，没有用动词三单
如：She can’t go to the party. → Who can’t go to the party?
She helps the girl. →Who helps the girl?
The boys are singing. → Who is singsing?
2.There be 句型的划线部分提问，问某地有什么
不管单数复数，用what’s或what is
如：There are some desks in the classroom.
What’ s in the classroom?
3.Whose的划线部分提问
Whose + 名词+ 其他
如：This is his book. → Whose book is this?
4.Why 的特殊疑问句一般遵循上述技巧，但是当原句存在否定时，有两种表述。

如：Yang Ling isn’t at school because she is ill.
Why isn’t Yang Ling at school?Why is Yang Ling not at school?
5.同时注意一些缩写
如：where is = where’s, what is = what’s, when is = when’s
4.改同义句（常见）
1）have a good time= have a lot of fun
2）It's time for ... = It's time to do ...
3）Give 某人+ 某物= Give 某物to 某人
4）show某人+ 某物= show 某物to 某人
5）What's wrong with ...= What's the matter with ..
6）a lot of = lots of = many
5.单复数句转换
1）单数改复数：所有单数改为复数
2）复数改单数：所有复数改为单数
如：I - we , me - us, my- our，he/she/it - they, him/her/it - them, his/her/its - their 数量：a - some, any be动词：am, is – are
名词也要单复数互换，特别是不规则名词man - men, foot - feet, sheep -sheep 1. He is a policeman.(改复数）
They are (some) policemen.
2.This is my pen.（改复数）
These are our pens.
3. Where are these books?（改单数）
Where is this book?
