Present Perfect Tense

Use the present perfect tense to write the sentence if you see the adverbs: ever, since, for, already, just, almost, never, yet, before.

  1. John (has read) the book already.
  2. Mary ( has left) just the house.
  3. Karen (hasn't come) yet.
  4. I (have never visited) Malaysia.
