2.Negatives

While writing negative verbs can be confusing, it’s fairly simple with the to be verbs. In the present and past tenses, put the negative word immediately after to be. 
You are not my enemy. 
She was never on time. 
For future tenses, put the negative word after will and before the bare infinitive be. 
We will not be attending. 
Don’t forget that you can use contractions with to be verbs. These are especially common in speech. 
This isn’t my cup of tea. 
It won’t be long now. 

3.Questions

The verb to be also follows its own rules for questions (interrogative sentences). While other verbs use the auxiliary verb to do for yes-no questions, to be does not. However, like other verbs, to be still comes before the subject in yes-no questions, even when it’s used as an auxiliary verb. 
Is that allowed? 
Were you listening?
Are they going now?
