• In the present simple to be has three forms (am, is, are), but in the past it has two forms ( was and were).

• In the interrogative forms (questions), we have: to be (am, is, are) + subject ?. Ex: are you?, is he? was she? was he? were you?

• In the negative forms, we, have: subject + to be (am, is, are) + not. ex: I am not, i was not , you are not, they were not, etc.

• We can write the verb by using two forms: short forms and full (long) forms.

  Ex: is not = isn't, are not = aren't, was not = wasn't, were not = weren't, etc.

• In the short answers, we have: yes, subject + to be. Ex: Yes, i am / Yes, she is.
