Negative sentence

Lesson 14

He is not here.
He isn’t here.
I cannot help you.
I can’t help you.
She is not sleeping.
She isn’t sleeping.


When we say a negative sentence, we put the word not after the first verb in a sentence. We do it for the verbs to be and can and also for the present continuous. When we speak, we often use short forms.


I do not cook.
I don’t cook.
She does not cook.
She doesn’t cook.


In the present simple we use don’t or doesn’t, when we say a negative sentence.

It isn’t a good day. I don’t know what to do. He can’t help me.
