La estructura del present perfect es:
| subject | + | auxiliary verb | + | main verb |
| have | past participle |
Vamos a ver algunos ejemplos para ver donde pueden estar los problemas:
| subject | auxiliary verb | main verb | |||
| + | I | have | seen | ET. | |
| + | You | have | eaten | mine. | |
| - | She | has | not | been | to Rome. |
| - | We | have | not | played | football. |
| ? | Have | you | finished? | ||
| ? | Have | they | done | it? |
Observa que hay dos cosas en las que nos podemos equivocar:
- La tercer persona (He, She, It) usa HAS en lugar de HAVE, si no sabes por que esto es así, deberías echar un vistazo a este ENLACE.
- Los verbos principales están en Past Participle, para los verbos regulares solo tienes que añadir "ed", los irregulares hay que memorizarlos

Ever & Never & Just & Already & Yet
Al igual que en español, el Present Perfect normalmente no viene solo, suele ir acompañado de adverbios, ya hemos estudiado Since, For y Ago, pasamos ahora a los que faltaban
We often use ever, never, just, already, and yet with the present perfect tense.
We use ever in interrogative sentences:
a. Have you ever been to the United States?
b. Have you ever traveled by train?
c. Have you ever failed a class?
We use never in affirmative sentences: but the meaning is negative.
a. I have never cheated in an exam.
b. My son has never been to Moscow.
c. My brother have never gone to London.
We use just to express a recently completed action.
a. The cat has just caught a bird.
b. The guests have just arrived.
c. I have just finished my homework.
We use already to express that something has happened sooner than expected.
a. Don't forget to bring your book! Oh, I have already brought it.
b. The boys are going to pack, aren't they? No. They have already packed.
c. Is Adam going to buy a new car? No, he isn't. He has already bought it.
We use yet in interrogative and negative sentences and it suggests a time later than expected.
a. Have you done your homework? No, I haven't done it yet
b. Has your father seen your report? No, he hasn't seen it yet
c. Have the visitors arrived? No, they haven't arrived yet.
