  6. 6. Examples I have seen that movie twenty times. I think I have met him once before. There have been many volcanic eruptions in Sicily. People have climbed Mount Everest. People have not traveled to Jupiter. Have you read the book yet?
  7. 7. How Do You Use the Present Perfect? • The idea of an “Unspecified time" can be confusing. It is best to associate Present Perfect with: • Experience • Change over time • Accomplishments • An uncompleted action you are expecting • Multiple Actions at Different Times
  8. 8. Experience • Present Perfect is used to describe your experience. It is like saying, "I have the experience of...” • You can use this tense to say that you have never had a certain experience. • The Present Perfect is NOT used to describe a specific event.
  9. 9. An action in the past… that affects us now… I have eaten some spicy food recently The food made me ill and I am taking a day off work I have not seen the film ‘E.T’ for two years. I really want to watch it again! I have lived in Opole since August 2011. It is a great place to live! Examples of Present Perfect…
  10. 10. What do these sentences mean? • I have been to Poland.This sentence means that you have had the experience of being in Poland. It is not clear how many times you have been there. • I have been to Poland three times.Now it is clear how many times you have been to Poland. • I have never been to Poland.This sentence means that you have not had the experience of going to Poland.
  11. 11. Change Over Time • We often use the Present Perfect to talk about change that has happened over a period of time. Examples: • You have grown since the last I saw you. • The government has become more interested in international cooperation. • English has become one of the most popular language courses at the local university since Poland joined the European Union. • My Polish has improved since I moved to Poland.
  12. 12. Accomplishments • We often use the Present Perfect to list the accomplishments of individuals and humanity. You cannot mention a specific time. Examples: • Man has walked to the North Pole. • Our son has learned how to solve Rubik’s cube. • Teachers have taught many students.
  13. 13. An Uncompleted Action You Are Expecting • We often use the Present Perfect to say that an action which we expected has not happened. Using the Present Perfect suggests that we are still waiting for it. Examples: • Alexandra has not finished her homework yet. • Piers hasn't mastered Polish, but he can talk. • Katie still has not finished reading the book. • The snow has not stopped.
  14. 14. Multiple Actions at Different Times • We can use the Present Perfect to talk about several different actions which occurred in the past at different times. Present Perfect suggests the process is not complete and more actions are possible. Examples: • The military has attacked that city five times. • I have had five tests and four quizzes so far this year. • We have had many problems while working on this project. • He has talked to several doctors about his problem, but nobody knows why he is sick.
  15. 15. Time Expressions with Present Perfect • When we use the Present Perfect it means that something has happened at some point in our lives before now. • Sometimes, we want to limit the time we are ‘looking in’ for an experience. We can do this with expressions such as: • in the last week, in the last year, this week, this month, so far, up to now, etc.
  16. 16. Examples • Have you been to Hungary in the last year? • I have seen that movie seven times in the last month. • They have had four tests in the last week. • She graduated from university less than two years ago. She has worked for four different companies so far. • My car has broken down five times this week.
  17. 17. Notice… • "Last year" and "in the last year" have very different meanings. • "Last year" means the year before now, and it is considered a specific time which requires. It is thus used with Simple Past. • “In the last year” means from 365 days ago until now. It is NOT considered a specific time and as such is used with Present Perfect. Examples: • I went to Hungary last year. (Simple Past) • I have been to Hungary in the last year. (Present Perfect)
  18. 18. Duration From the Past Until Now • With non-continuous verbs, we use the Present Perfect to show that something started in the past and has continued up until now. Expressions such as “For six minutes” & “Since Sunday”, are used with the Present Perfect. Examples: • I have had a bad temper for two weeks. • She has been in Romania for six months. • Katie has loved ham since she was a little girl.
  19. 19. ADVERB PLACEMENT • The examples below show the placement for grammar adverbs such as: • always, only, never, ever, still, just etc. Examples: • You have only seen that film one time. • Have you only seen that film one time?
  20. 20. ACTIVE sentences • The thing doing the action is the subject of the sentence and the thing receiving the action is the object. Most sentences are active. Form • Subject + has/have + past participle form of the verb + object
  21. 21. Passive sentences • The thing receiving the action is the subject of the sentence and the thing doing the action is optionally included near the end. • You can use the passive form if you think that the thing receiving the action is more important or should be emphasized. • You can use the passive form if you do not know who is doing the action or if you do not want to mention who is doing the action. Form • Object of the active sentence + has/have + been + past participle form of the verb + by + subject of the active sentence
  22. 22. Examples Active: I have written a book. Passive: A book has been written by me. Active: They have built a bungalow. Passive: A bungalow has been built by them. Active: He has broken my door. Passive: My door has been broken by him. Active: I have placed an order for a computer. Passive: An order for a computer has been placed by me. Active: She has done her homework. Passive: Her homework has been done by her.
