When do we use each tense in
English?

12. Remember:
Grammar has meaning!
Different grammar tenses are used
in different situations or contexts
and they carry different meanings.
For example . . .

13.  Use the simple  Use the present
past for action perfect for
that happened in action that
the past and is: started in the
past, but . . .
over, done,
finished! is still true
today.

14.  The simple past always refers to an
action or situation that is finished.
 The present perfect connects the
past and the present. It is used to show
that an action or situation in the past:
- continues today, OR
- might happen again

15. Compare the meaning of these
two sentences:
1. Sara lived in Boston for 5 years.
2. Sara has lived in Boston for 5 years.
The first sentence uses:
Simple Past
The second sentence uses:
Present Perfect

16. Sara lived in Boston for 5 years.
Meaning: by using the simple past
tense, we mean that Sara started
living in Boston 5 years ago . . .
AND . . . then she moved!
Now she lives in a different city,
like Paris.
Remember, the simple past is used
for a situation that is over,
finished, done!

17. Sara has lived in Boston for 5 years.
Meaning: by using the present
perfect tense, we mean that Sara
began living in Boston 5 years
ago. . .
AND . . . she still lives there.
Remember, present perfect:
connects the past with the present.

18.  Use the simple  Use the present
past with time perfect with
words like: time words like:
• yesterday • recently/lately
• last Saturday, week, • since …
month, year, etc.
• so far this
• _______ ago week, month, year, etc.
• when I was…
• in 1990 (past date)

19. Additional notes about
present perfect:
• We often use present perfect to say
that something happened sooner than
expected.
Example:
Jan: Don’t forget to mail that letter.
Tom: I’ve already mailed it.

20. • We often use present perfect to say
that we have never done something at
any time in the past.
Example:
I have never visited London. But
someday, I hope to travel there.

21. • We often use present perfect with the
expression: “This is the first time.”
Example:
Leonard is nervous. This is the first
time he has flown on an airplane!

22. • We often use present perfect with
“ever” and “never.”
Example:
Patricia: Have you ever played tennis?
Linda: No, I’ve never played before, but
I would like to learn!

23. Remember!
If you are talking about a specific
time in the past (yesterday, last
month, etc.), you cannot use the
present perfect.
In these cases, use the simple past.
