2. PRESENT PERFECT SIMPLE
Good morning!
Today I’m going to tell you
something about the
Present Perfect Simple...

3. WHEN DO YOU HAVE TO USE IT?
this tense is used to speak
about actions begun in the
past, but that have
consequences on the
present

4. HOW DO YOU FORM IT ?
SUBJECT + HAVE/HAS + PAST PARTICIPLE
Ex. I have broken my
leg
This thing happened in
the past, but I still have
a broken leg now

5. NEGATIVE AND INTERROGATIVE
FORM
NEGATIVE ONE:
subject + have/has not + past participle
ex. I have not (haven’t) done my homework yet
INTERROGATIVE ONE:
have/has + subject + past participle
ex. Have you done your homework yet?

6. FOR AND SINCE
We use them to
speak about the
moment when an
action, that has
lasted some time,
began
FOR
how much
time
SINCE when
Ex. For

Ex. Since
I have studied French for many years

7. JUST, ALREADY, STILL AND YET
we use them to say an
action has finished not
much time ago, or it is
going on even now, or it
has ended before we
thought

8. JUST AND ALREADY
You can use them in positive and interrogative
sentences
ex. Sally has just left university
Sally ha appena lasciato l’università
This action has ended recently, and now Sally is a graduate (consequence on
the present)
ex. Have you already eaten?
Avete già mangiato?
We use already when we want to underline the surprise about an action. In this
case I thought you’d have dinner later, so I’m surprised.

9. STILL AND YET
ex. I still haven’t found my keys
Non ho ancora trovato le mie chiavi
I haven’t asked him yet

you can use them in negative and
interrogative sentences
