Verbs
From TEFL World Wiki
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 their tense and form to change the meaning and tell us when something happens (past, present, future).
To make some tense 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.
(past continuous or progressive)
I worked yesterday.
(past simple)
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 or the crop will die!
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.
