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.
