单词This is anegg That is Tom It is adesk Those are变为否定句一般疑问句肯定句否定回答怎末变?

答案

This is not an egg.
Is this an egg?
Yes,this is.
No,this isn't.
That is not Tom.
Is that Tom?
Yes,that is.
No,that isn't.
It is not a desk.
Is it a desk?
Yes,it is.
No,it isn't.
否定句的变法：：（1）若句中有系动词（am,is,are)的,直接在后面加not
（2）若句中没有系动词的 在动词后面直接加not.
一般疑问句的变法：（1）若句中有系动词（am,is,are)的,直接将系动词提前,再将主动词,既实意动词变为一般形式,例如：My name is Gim Tadder 变为一般疑问句既是：Is your name Gim Tadder?（2）若句中没有系动词的,在句前家do,例如：I like reading books.变为 Do you like reading books?
