When we want to talk about what the subject of a sentence does, we use a verb. Verbs tell us about an action. Here are some simple verbs:
run, walk, read, talk
When we use verbs, we can change theirtense and form to change the meaning:
I work; She works; I worked; I have worked; I am working
This change tells us when something happens (past, present, future).
To make sometense changes, we use different forms of the verb:
I was working.
I worked.
I work.
Some verbs are continuous or progressive, and some are simple; they have the same time reference but have different meanings:
I was working yesterday.
I worked yesterday.
We can also use modal verbs to tell us about how we feel about something happening:
You should see a doctor.
It must rain soon.
Some verbs always go with the same preposition:
I succeeded in passing my driving test.
She listened to the radio last night.
When we join two verbs to make a verb phrase, we use certain patterns:
I want to go.
I must go.
