Present Perfect Uses

The present perfect has 2 main uses:

1. Actions in the past with no specific time
2. Actions in the past that continue into the present

No Specific Time

Present perfect is for actions in the past with no time. This could be for a number of reasons:

• Time is unknown
• Time is not important
• The action has happened many times

Let’s think about a few examples.

• He has found his keys.
• I have gone to New York City 3 times.
• I have not finished my project.
• We have seen that movie many times.

In this example, it is not important when he found his keys. We only care he found them.

This example shows an action that has happened many times. Because the present perfect has no specific time, it is not used with time phrases. These examples are incorrect.

• I have eaten lunch yesterday.
• She has taken an English class last year.

In a situation with a specific time, use the simple past. For example:

• I ate lunch yesterday.
• She took an English class last year.

Actions that Continue to the Present

Some actions start in the past, but they continue in the present. This is shown with the present perfect.

Examples:

I have lived in Paris for 3 years.

(I live in Paris now.)

She has worked as a teacher since 2003.

(She started to teach in 2003. She is a teacher now.)

I have been a student at this school for 2 years.

(I am still a student.)

Вопрос

Учимся формировать общие вопросительные предложения в Present Perfect:

Вспомогательный глагол	Подлежащее: существительное или местоимение	Сказуемое: глагол
Have	I, you, we, they students (they)  my family and I (we)	глагол в третьей форме (V3) played, studied, worked
Has	he, she, it Bob (he) Mary (she) dog (it)

• Have people (they) travelled to space? — Люди путешествовали в космос?
• Has Bob (he) studied architecture? — Боб изучал архитектуру?
• Has Mary (she) read this book? — Мэри читала эту книгу?
• Have you bought a car? — Ты купил машину?

На вопросы приходится отвечать. В английском нельзя ответить просто yes или no, в ответе нужно использовать вспомогательный глагол: 

Как запомнить. Слушайте внимательно вопрос, в нем всегда есть элементы ответа. В вопросе «Has Mary bought a car?» уже есть вспомогательный глагол has и Mary (she). Это поможет ответить правильно: Yes, she has. 

Часто вопрос начинается со специального вопросительного слова: 

• when — когда
• who — кто
• where — где
• why — почему

Примеры вопросительных предложений и ответов

Чтобы составить вопрос в Present Perfect, нужно have/has вынести вперед, перед подлежащим. Например:

• He has done it (Он сделал это)
• Has he done it? (Он сделал это?)

Краткий ответ состоит из Yes + местоимение, заменяющее подлежащее + have / has. No + местоимение, заменяющее подлежащее + haven’t / hasn’t. Например:

• Have they arrived? — Yes, they have.  (Они приехали? — Да.)
• Has Nina called you? — No, she hasn’t. (Нина звонила тебе? — Нет.)

Специальный вопрос начинается с вопросительных слов Where, What, When, Why, How и тд.

Why has he done it? (Почему он это сделал?)

Примеры отрицательных предложений

Отрицательная форма в Present Perfect образуется с помощью частицы not после глагола have/has и глагола с окончанием -ed или в третьей форме.

Вместо частицы not может использоваться слово never (никогда). Хотя в русском языке мы используем частицу не после никогда «я никогда не…», в английском слова never достаточно. Например: I have not been there (Я не был там) — I have never been there (Я никогда не был там).

В разговорной речи распространена сокращенная форма: have not — haven’t, has not — hasn’t.

Полная форма	Сокращенная форма	Перевод
I have not received any letter.	I haven’t received any letter.	Я не получил накакого письма.
They have not been to the museum yet.	They haven’t been to the museum yet.	Они еще не были в музее.
We have not seen them lately.	We haven’t seen them lately.	Мы их не видели в последнее время.
I have not thought of it since yesterday.	I haven’t thought of it since yesterday.	Я не думал об этом со вчера.
My parents have not used Skype before.	My parents haven’t used Skype before.	Мои родители раньше не пользовались скайпом.
She has not come back from school yet.	She hasn’t come back from school yet.	Она еще не вернулась из школы.)
He has not lost his ticket.	He hasn’t lost his ticket.	Он не потерял свой билет.
The plane has not taken off yet.	The plane hasn’t taken off yet.	Самолет еще не взлетел.
Lola has not been there for 5 years.	Lola hasn’t been there for 5 years.	Лола не была там 5 лет.
Nick has not finished his exam yet.	Nick hasn’t finished his exam yet.	Ник еще не закончил свой экзамен.

Случаи употребления Present Perfect

Мы разделили правила употребления Present Perfect на три уровня сложности: простые, чуть сложнее и сложные. Если сложно запомнить все и сразу, запомните сначала простые примеры настоящего совершенного времени.

Простые случаи употребления Present Perfect

Действие совершилось в прошлом или недавнем прошлом (не важно точное время), и виден результат (а вот результат очень важен)

Bob has bought a house. — Боб купил дом

(Боб купил его в прошлом, не так важно — когда именно. Зато важен результат — новый дом)
I know Mary. We have already met. — Я знаю Мэри. Мы уже встречались. (Познакомились в прошлом, и вот он результат — мы знаем друг друга)
Mary has lost her wallet, she can’t pay the bill. — Мэри потеряла кошелек, и теперь не может оплатить счет. (Результат потери кошелька в прошлом влияет на настоящее — Мэри не платежеспособна).
Действие произошло в незаконченный период времени — this week (на этой неделе), this morning (сегодня утром), today (сегодня)

This week we have watched 5 episodes. — На этой неделе мы посмотрели 5 серий. (Неделя еще не закончилась, кто знает — сколько еще серий мы посмотрим)
Today I have visited the dentist. — Сегодня я посетил зубного врача. (Я уже это сделал, но сегодня еще не закончилось) 
Опыт, который с вами случился. Как-будто вы говорите «У меня есть опыт изучения английского»

Have you ever been to Russia? — Ты был когда-нибудь в России?
Mary has been to Moscow. — Мэри была в Москве.
I have never eaten noodles. — Я никогда не ел лапшу.
Bob has studied English. — Боб учил английский

Чуть более сложные случаи употребления Present Perfect Изменения, которые произошли с течением времени The child has grown since the last time I saw him. — Ребенок вырос с прошлого раза, когда я его видел. The humanity has become more aware about global warming. — Человечество стало больше знать о глобальном потеплении.  Незавершенное действие, которое вы ожидаете Students have not finished the task yet. — Студенты все еще не закончили домашнюю работу. Bob has still not arrived. — Боб все еще не приехал. Достижения, которые не привязаны к конкретному времени Doctors have cured many deadly diseases. — Доктора вылечили много смертельных заболеваний. Mary has learnt how to drive. — Мэри научилась водить.  Действие, которое началось в прошлом, и все еще продолжается и актуально на сегодняшний момент Mary has known Bob since school. — Мэри знает Боба со школы.  Mary has been a teacher since 2000. — Мэри работает учителем с 2000 года. My sister has wanted to become a doctor since childhood. — Моя сестра хочет стать доктором с детства.  Отрицательные действия, которые мы не делали какое-то время Mary hasn’t heard from Bob for the last 2 months. — Мэри не слышала ничего от Боба последние 2 месяца. We haven’t been to London since last summer. — Мы не были в Лондоне с прошлого лета.

Сложные случаи употребления Present Perfect Новости, которые случились недавно. О самом событии мы говорим в Present Perfect, а рассказ о деталях продолжаем в Past Simple.  Mary has passed a driving test! First they asked her to turn left, then she drove 2 kilometers in the city and parked safely. — Мэри сдала экзамен по вождению! Сначала они попросили ее повернуть налево, потом она ехала 2 километра по городу и безопасно припарковалась.

Маркеры времени Present Perfect

Слова-маркеры, слова-якоря или вспомогательные слова указывают на время Present Perfect. Если вы хотите сказать или написать такое слово — скорее всего, все предложение будет в Present Perfect. 

А вот примеры с этими словами:

• Bob hasn’t arrived yet. — Боб еще не приехал.
• Mary has already passed a test. — Мэри уже сдала тест.
• Have you ever tried pizza? — Ты когда-либо ел пиццу?
• I have never been to London. — Я никогда не был в Лондоне.
• I have bought a new car recently. — Я купил новую машину недавно.
• Bob hasn’t heard from Mary lately. — Боб не слышал от Мэри ничего в последнее время.

• He has not eaten since 3 pm. He has not eaten in 6 hours.

To practice the difference between for and since, use this test:

 Yet

“Yet” is for negative sentences and questions. It always goes at the end of the sentence. Here are some examples:

Negative Sentences

• I have not eaten dinner yet.
• She has not seen that movie yet.
• They have not arrived yet.

 Questions

• Have you eaten dinner yet?
• Has he seen that movie yet?
• Has Tina arrived yet?

Already

“Already” is for affirmative sentences. It can go at the end of a sentence:

• I have eaten dinner already.
• She has taken the test already.
• Dan and Jen have had breakfast already.

It also goes between the auxiliary and the main verb:

• I have already eaten dinner.
• She has already taken the test.
• Dan and Jen have already had breakfast.

Here are some more examples:

• She has already
• He has left already.
• Jake and Fred have already finished their work.

 Still

Still is for negative sentences. It goes before the auxiliary verb.  Here are some examples:

• I still have not eaten dinner.
• She still has not arrived.
• Chris still hasn’t woken up.
