Grammar: Present Perfect – Теперішній перфектний час (1)

have / has + V3 / Ved


Стверджувальна форма Заперечна форма Питальна форма
I/you/we/they've (= have) worked / begun… He/she/it’s (= has) worked/ begun… I/you/we/they haven’t worked / begun… He/she/it hasn’t worked / begun… Have I/you/we/they worked / begun…? Has he/she/it worked / begun…?


• Present Prefect утворюється з допоміжного дієслова haveу Present Simple та дієприкметника минулого часу (Past Participle) основного дієслова.

У питально-заперечній формі допоміжне дієслово ставиться перед підметом, а частка not - після підмета:

Why have you not told me about him? - Чому ти не розповів мені про нього?

У питально-заперечних реченнях здебільшого вживаються скорочені форми haven't і hasn't,які ставляться перед підметом:

Hasn't he been to Kyiv? - Невже він не був у Києві?

Whyhaven'tyou put on your coat? - Чому ти не одягнув пальто?

• Present Perfect вживається для вираження дії, яка відбулась до моменту мовлення, і той, хто говорить, має на увазі результат цієї минулої дії, її важливість на момент мовлення:

Іhave locked the door. - Я замкнув двері.

Have youturnedoff the gas? - Ви вимкнули газ?

• Час дії, вираженої дієсловом у Present Perfect, здебільшого не зазначається, тому що у центрі уваги результат дії, а не час її перебігу:

Youhaven’t toldme the whole story. - Ви не розповіли мені всього.

What havethey done?- Що вони зробили?
