When we use WHILE, the structure is the following:

PRESENT PERFECT

1) We use present perfect for actions done in a period of time which has not finished yet
(today, this week, this year….)

Have you seen Jack this week?

It hasn´t rained much this year

2) We use present perfect to talk about events happened recently

He has written that email

PRESENT PERFECT WITH EVER, NEVER, YET, JUST AND ALREADY

These adverbs are often used with Present Perfect.

We use EVER in questions with Present Perfect to express the idea of “sometime in your life”.

The structure is:

HAS/HAVE+ SUBJECT + EVER + PAST PARTICIPLE

Have you ever been to Paris?

We use NEVER when we want to express the idea of “I have never done something”

The structure is:

SUBJECT + HAVE/HAS + NEVER + PAST PARTICIPLE

I have never eaten raw fish

YET is used to ask if and action has been completed and to negate and action has not been
completed though the action is expected to be done. It is placed at the end of the sentence.

Have you asked her yet?

I haven´t started to read the book yet

ALREADYis used to emphasize an action has been completed. It is used in the affirmative and it
is placed between the auxiliary verb HAVE/HAS and the past participle.

Have you already finished?

I have already booked the room
