将下列句子先变为否定句,再变为一般疑问句,并作肯定和否定回答:
1、This is an eraser.
2、That's her book.
3、He's a good boy.
4、I’m her teacher.
5、she is a nice girl.
单把答案给你不行吧,下次又不懂有得问了……还是讲解一下为好:
把句子改成否定句,先要把谓语改为否定形式:V.+not 或其所写的否定形式,若欲知如何,请详查有关书籍,在此不做相关归纳.改为一般疑问句,就分两种情况:1.谓语为Be动词时,就把Be动词放到句子前面,然后后面的词语按顺序照抄.2.谓语为普通动词时,就依时态行事,根据时态变化.一般来说,就是找到相应的时态的助动词,把其放到句首,把原句中的动词通通改为原型,然后按原句的单词顺序在助动词后面照抄即可.
答案:1.This is not an eraser./This isn't an eraser.
Is this an eraser?
Yes,it is.
No,it is not./No,it isn't.
2.That's not her book./That isn't her book.
Is that her book?
Yes,it is.
No,it's not./No,it isn't.
3.He's not a good boy./He isn't a good boy.
Is he a good boy?
Yes,he is .
No,he's not./No,he isn't.
4.I'm not her teacher.
Are you her teacher?
Yes,I am.
No,I am not./No,I 'm not.
5.She is not a nice girl./She isn't a nice girl.
Is she a nice girl?
Yes,she is.
No,she is not ./No,she isn't.
下次应该明白了吧?
