8. Definition: We use the reflexive pronouns to indicate that the person who
does the action of the verb is the same person who receives the action.
Example 1: I cut my hair myself.
* In this example "I" does the action of cutting the hair and at the same
time "I" gets the action of the hair being cut.
Example 2: We defended ourselves brilliantly.
* In this example the reflexive pronoun "ourselves" refers back to the
subject of the sentence.
Example 3: John talks to himself when he is nervous.
* In this example "Himself" refers to John

definite time. We use just in positive sentences to say that
something happened very recently.

they are really pleased.
13. USES OF THE PRESENT PERFECT

experiences, there is not a definite time given. The time
expressions ever and never are very often used with this
meaning

14. USES OF THE PRESENT PERFECT

are still continuing in the present, the time period is not
finished.

(And I haven¡¯t found them yet.)
15. WE OFTEN USE THE PRESENT PERFECT TENSE
WITH ALREADY AND YET
Already: Something happened before now or earlier than expected
You can use already in positive sentences. Put already before the
main verb.
Yet: Until now.
You can use yet in negative sentences and questions. Yet is usually
at the end.
Example: A) Have you done your homework yet?
B) No, I haven¡¯t done it yet. / Yes, I¡¯ve already done it.
