DATE: SEPTEMBER 2013
CREATED BY: Miguel Angel Esquivel
COURSE: CL-5
1. Unspecific time and finished actions

Paola has

American and British universities.

For regular verbs
The past simple form and past participle form is the same.
We add -ed to the verb.

Example:

Kelly and her sister have started their own business.
Have you ever traveled by plane?

3. Unfinished actions
When an action started in the past and is still in progress, we can use the present perfect tense.

We usually associate this tense with :


for
two hours, six weeks, 20 years, etc.


since
last week, January, 2007, I was 5, etc.

already
If we want to know the period of time an action is taking since it started, we usually use: how long

and

examples
