PRESENT PERFECT TENSE

Present tense its emphasis on facs, events repeatedly becoms a habit, 

and present continous tense emphasis on "was" going.

Present Perfect Tense the formula is like this:
+: S + have/has + V3
- : S + have/sas Not + V3

? :   Have/has + S + V3

 Example : 

+ :  She has gone (Dia baru saja pergi)

-  : She has not gone

? :   Has She gone?

-I have written english lesson for 30 minutes

-You have read my lesson since 2 PM

Note the verbs change :

- Write – wrote – written (berubah)

- Read – read – read  (lah kok sama? haha xD)

Take another example, the positive :

-I have cleaned the floor

-He has drunk milk

-You have just broken the glass

How negative sentence ? He has not drunk milk! you try the others 

two yes. Sentences in the present perfect tense asked to stay behind

the formula above was appropriate. Remember do not forget his 

partner to "Have" and "Has".

- has she drunk milk ?
