Definitions
of Tenses:
The
Two Present Tenses:
Most
English verbs have two “present”
tenses. Forms like I wait,
she thinks are called ‘simple present’
or ‘present simple’;
forms like I am waiting
or she’s thinking
are called ‘present progressive’
or ‘present continuous’.
Modal verbs like can or must do not have
progressive forms, and some other verbs such as known
or contain are
rarely used in progressive forms. The two ‘present’
tenses are used to refer to several different kinds of time.
The
Six Past Tenses:
In
English, six different tenses are used to talk about the past:
The
simple past (I worked)
The past progressive (I was working)
The simple present perfect (I have worked)
The present perfect progressive (I have been working)
The simple past perfect (I had worked)
The past perfect progressive (I had been working)
The
difference between these tenses is quite complicated. Some
English tenses express meanings (e.g. complication,
continuation, present importance), which are not expressed by
verb forms in all other languages, and this can make the use of
tenses difficult for individuals to learn.
