5. Present Perfect Simple and Present Perfect Continuous

Present Perfect употребляется для выражения действия, законченного к настоящему моменту и связанного с этим моментом.

Present Perfect используется:

1) для констатации факта совершения действия без указания на время его совершения: I have written a letter.

2) когда указан период времени, который еще не закончился: today, this week, this month, this year: I haven’t seen Ann today.

3) с наречиями never(никогда), ever(когда-либо), just(только что), yet(еще), аlready(уже): Nick has just come back.

4) с обстоятельствами времени, указывающими на период, в течение которого происходило или могло происходить действие, начиная с какого-то момента прошедшего времени и вплоть до настоящего времени: lately(в последнее время), for a long time(в течение долгого времени), how long(как долго), so far(до сих пор), up to now(до настоящего момента), for three hours(в течение трех часов), since(с тех пор как): Have you been to the cinema lately?

Present Perfect образуется при помощи вспомогательного глагола to have и причастия прошедшего времени(Particle II) смыслового глагола. Particle II правильных глаголов образуется при помощи окончания -ed к неопределенной форме глагола: to ask- asked, to work – worked;

Particle II неправильных глаголов образуется чередованием звуков в корне (3-я форма глагола): go – went – gone, do – did – done.

I/You/We/They’ve (have) worked	Have I/you/we/they worked?	I/You/We/They haven’t (have not) worked.
He/she/It’s (has) worked.	Has he/she/it worked?	He/she/It hasn’t (has not) worked.

Present Perfect Continuous обозначает действие или состояние, которое началось в прошедшем и продолжалось в течение определенного периода до момента речи и либо еще продолжается в этот момент, либо закончилось непосредственно перед ним. Present Perfect Continuous образуется при помощи вспомогательного глагола to be в соответствующем перфектном времени (настоящем, прошедшем или будущем) и причастия настоящего времени (Present Participle) смыслового глагола.

I have been waiting for you for three hours.

Stative verbs (глаголы состояния) не употребляются в Present Perfect Continuous. Stative verbs :

∙ feelings: hate, like, love, prefer, want.

∙ thoughts: believe, feel, know, think, understand.

∙ possession: belong, have, own.

∙ senses: feel, hear, see, smell, sound, taste.

∙ appearance: appear, look (like), seem.
