Use of the simple present of to be
The principal use of the simple present is to refer
to an action or event that takes place habitually, but with the verb "to
be" the simple present tense also refers to a present or general state,
whether temporary, permanent, or habitual.
§ I am happy.
§ She is helpful.
The verb to be in the simple present can be also
used to refer to something true at the present moment.
§ She is 20
years old.
§ He is a
student.
Remember:
§ I, you, he, she, it, you, they are subject pronouns (also called personal pronouns, a term
used to include both subject and object pronouns.)
§ am, are, is are forms of the verb to be in the simple
present.
§ 'm, 're, 's are short (contracted) forms of am, are, is
§ 'm not, aren't, isn't are short (contracted forms) of am not, are not, is not.
Usually, the subject of a Wh- question comes after the verb.
Dana was talking to Rob.
However, when Who or What is the subject of a question, we don't use a subject after to be.
Sam is in the car.
Nothing is wrong.
In spoken English, we often use contractions combining question words with is and are.
- Who's / What's / Where's / When's / Why's / How'sWho's that?What's that?How's it possible?
- Who are / What are / Where are / When are / Why are / How areWho are they?Why are we here?How are they now?
We can form negative Wh- questions with am not, isn't, andaren't
