Szie!
Present Perfect:
have/has + V3
Tehát az első feladatban csak el kell dönteni hogy have vagy has és hogy mi a harmadik alak.
1.
1 Has Kelly brought
2 haven't planted; have built
3 have collected
4 has bought; hasn't fixed
5 Have you told
6 has asked

2. Meg kell keresni melyik részt "helyettesíti" az adott szó és azt kivenni, a szót pedig betenni a jó helyre.
2 I have seen this film twice.
3 Have you ever camped in the country side?
4 I have always wanted a dog.
5 I haven't been on a working holiday before.
6 We have already decorated the house for the party.
7 I haven't finished the book you gave me.

Nagyjából ennyi, ha van valami kérdésed írj nyugodtan!
