Simple present

The simple present is a verb tense with two main uses. We use the simple present tense when an action is happening right now, or when it happens regularly (or unceasingly, which is why it’s sometimes called present indefinite). Depending on the person, the simple present tense is formed by using the root form or by adding ‑s or ‑es to the end.

I feel great! Pauline loves pie. I’m sorry to hear that you’re sick.

The other is to talk about habitual actions or occurrences.

Pauline practices the piano every day. Ms. Jackson travels during the summer. Hamsters run all night.

Typically, when we want to describe a temporary action that is currently in progress, we use the present continuous: Pauline can’t come to the phone right now because she is brushing her teeth.

Verb Be

Verb To Be

The verb “To be” is said to be the most protean of the English language, constantly changing form, sometimes without much of a discernible pattern. Considering that we use it so often, it is really too bad that the verb “To be” has to be the most irregular, slippery verb in the language.

Present Tense
I am	We are
You are	You are
He/She/It is	They are

Past Tense
I was	We were
You were	You were
He/She/It was	They were

Perfect Form (past participle) I have been, etc.

Progressive Form (present participle) I am being, etc.

We must choose carefully among these various forms when selecting the proper verb to go with our subject. Singular subjects require singular verbs; plural subjects require plural verbs. That's usually an easy matter. We wouldn't write “The troops was moving to the border.” But some sentences require closer attention. Do we write “The majority of students is (or are) voting against the referendum"? Review carefully the material in our section on Subject-Verb Agreement, and notice how often the choices we make require a familiarity with these forms of the “To be” verb.

Sentences & Parts of the speech

A sentence is a group of words that makes complete sense, contains a main verb, and begins with a capital letter. 

Sentences are used:


To make statements:

I took some money out of the bank.
The shop stays open until 9 p.m.

To ask questions or make requests:

Can I help you?
Could you open the door?

To give orders:

Stop arguing!
Come here at once!

To express exclamations:

You’re driving too fast!
It’s so cold!

THE EIGHT PARTS OF SPEECH
