PERFECT TENSE : PPT

PERFECT TENSE : PPT

Use the present perfect tense when :
> Something happened in the past, and
> The result of happening is still there.

Example :
1. I have closed the window
(The result : The window is still close)
2. Indah has gone to America.
(The result : Indah is still in America)



This is different from the simple past tense :
1. I closed the window
(The result : You don't know if the window still closed or not)
2. Indah went ti America.
(The result : She is no longer in America)

*The Affirmative form
Pattern : S + Auxiliary Verb (Have/Has) + past participle + ....
Example :
1. He has bought a car here (He has the car)
2. I lived in Japan (I know Japan)

This tense often uses "for" and "since" especially to express the continuing events (peristiwa yang masih berlanjut)
Example :
1. I have been here for 15 minutes
2. I have been here since 9 O'clock

Contraction of 's may be confusing sometimes.
It can come from verb be (is) or the auxilliary has. But you can understand it from the context. The key are :
>The contraction of 's from the auxulliary verb has when it is followed by past particple.
>The contraction of 's from the verb be (is) when it is followed by nouns, adjective, or V-ing.

Example :
1.She's borrowed my book.
(Auxulliary has)
2.She's listening to music.
(verb be)


*The negative form
Pattern : S + Auxilliary Verb (Have/has) + not + Past Participle + ....
Example :
1.Susi has not gone to the movie.
2.He has not finished repairing the radio.

*The interrogative form
Pattern : Auxilliary (Have/has) + S + Past Participle + ... + ?
Example :
1.Has Nina finisher his homework ?
2.Have students done their assignments ?

The present perfect tense often uses adverb "just, ever, never, and already", especially to express the speaker's experiences or new information.
(Note : never = not ever)

Example :
(+) We have just lived in Japan
( -) We have not just lived in Japan
(?) Have we just lived in Japan ?
