Answer 1

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.

No,it is not./No,it isn't.
2.That's not her book./That isn't her book.
