Настоящее совершенное продолженное время

Form and Structure

• The present perfect continuous tense describes an action that began in the past and continues up to the present.
• It's formed using "have/has" + been + present participle (verb + -ing).
• Examples:
  • I have been working on this project for three hours.
  • They have been playing tennis all afternoon.
  • She has been studying English for five years.

Uses and Functions

• Action continuing up to the present: This is the primary use. It emphasizes the duration of an action that started in the past and is still happening.
• Recent actions with a continuing effect: The action might have finished a short time ago, but the effect continues now.
• Duration in relation to the present: It helps describe how long an activity has gone on, highlighting the continuity.
• Describing an experience that has changed you: This past experience might be ongoing, making you different now.

Examples in Context

• "I have been feeling unwell all week." (Describes a recent, extended duration of illness.)
• "They have been preparing for the marathon for months." (Highlights the length of their preparation.)
• "She has been attending yoga classes, which is why she's more flexible." (Connects past action to a current state.)
• "We have been waiting for the train for almost an hour." (Emphasizes the duration and continuing effect of waiting.)
• "He has been working overtime recently, leading to exhaustion."
• (Shows a relationship between past work and a current result.)

Common Mistakes

• Confusing with simple present perfect: The present perfect simple describes an action that happened once or multiple times at an unspecified time; the continuous highlights that the action is ongoing.
• Misuse of time expressions: While certain time expressions work with the present perfect continuous, the wrong ones can make the sentence semantically incorrect.
• Incorrect use of adverbs for duration: Using an adverb like "recently" or "lately" isn't enough – the present perfect continuous must match the duration emphasis.
• Forgetting the "been": It's a crucial component of the tense. Leaving it out will change the meaning.

Time Expressions

• General duration and continuation:
  • All day/week/month
  • For three years/an hour/two months
  • Since Monday/1990/last year
• Emphasis on recentness:
  • Recently
  • Lately
  • In the last few weeks/days
  • Just
• Emphasis on duration leading to a present state or consequence:
  • For a long time,
  • All morning/afternoon
  • Since last week/2000
• Incorrect usage example:
  • "I am working on this project (incorrect, because it's not ongoing - should be "have been working")"
