TENSES

Verb Tense Review
The Importance of Time

      Verb tense expresses the time of an event or action. Time and how it is expressed in writing is very important to English readers.   The English language has twelve different tenses.  In this lesson, we will review the meaning of each verb tense.

The Simple Present Tense
      Expresses a habit or often repeated action.  Adverbs of frequency such as, often, seldom, sometimes, never, etc. are used with this tense.

 She goes to work everyday.
 They always eat lunch together

This tense also expresses general truths or facts that are timeless.

Snow falls in the December in Minnesota.
Water boils at 100 degrees Celsius.

The Present Progressive
      This tense is used to describe an action that is occurring right now (at this moment, today, this year, etc.).  The action has begun and is still in progress.

She is typing a paper for her class.
He can’t talk.  He is fixing the sink right now.
The present progressive can also be used to describe an action that is occurring in the present, but is temporary.

John is living in Modesto, but he might move soon.

 The Simple Past
      We use the simple past to indicate exactly when an action or event took place in the past.

I visited my sister yesterday.
We went out to dinner last night.

The simple past is used to describe actions and/or events that are now completed and no longer true in the present.

I attended MJC in 1998.  (I no longer attend MJC.)
I saw a movie every weekend when I was a teenager.  (I don’t see movies very much anymore.)

The Past Progressive
     The past progressive is used to talk about an activity that was in progress at a specific point of time in the past.  The emphasis is on the duration of the activity in the past.

I was studying for an exam while my mother was cooking dinner.
We were walking in the park around 7 p.m. last night.
 
The past progressive is often used with the simple past to show that one action was in progress when another action occurred
 
I was taking a bath when the doorbell rang.
They were eating dinner when the neighbors stopped by for a visit.

The Present Perfect
     The present perfect is used to talk about an event that began in the past and continues up to the present.

He has lived in Modesto for two years. (He began living in Modesto two years ago and he still lives
there.)
The present perfect is also used to talk about an event that was completed in the past, but the specific
time of the event is not important.

I have seen that movie before.
He has already visited Vietnam. (Specific dates and times are not mentioned.)

Present Perfect Progressive
     This tense is used to describe the duration of an action that began in the past and continues into the
present.

He has been studying grammar for an hour.
She has been cooking all day.
(He is still studying and she is still cooking.)

This tense is also used to describe events that have been in progress recently and are rather temporary.
She has been living in Taiwan for the last two months, but she plans to move soon.

The Past Perfect
     This tense describes completed events that took place in the past before another past event.

I had already eaten when my friend stopped by to visit.

Past Perfect Progressive
     This tense is used to emphasize the duration of an action that was completed before another action

The Future

The simple present and present progressive are also used to express future time.  These are often used
used in connection with schedules.
