PRESENT PERFECT SIMPLE ANALYSIS

1. Typical model of the item/pattern:

The present perfect is formed by combining has or have with a past participle (usually a verb ending in -d, -ed, or -n).

PRESENT PERFECT SIMPLE | PRESENT PERFECT CONTINUOUS |
Subject + have/has + verb in past participle * You have seen that movie many times. * Have you seen that movie many times? * You havenot seen that movie many times. * | Subject + has/have + been + present participle * You have been waiting here for two hours. * Have you been waiting here for two hours? * You have not been waiting here for two hours. |

2. Concept (s)

An aspect of the verb expressing an action that began in the past and which has recently been completed or continues into the
present.PRESENT PERFECT SIMPLE | PRESENT PERFECT CONTINUOUS |
USE 1 Unspecified Time Before NowWe use the Present Perfect to say that an action happened at an unspecified time before now. The exact time is not important. You CANNOT use the Present Perfect with specific time expressions such as: yesterday, one year ago, last week, when I was a child, when I lived in Japan, at that moment, that day, one day,etc. We CAN use the Present Perfect with unspecific expressions such as: ever, never, once, many times, several times, before, so far, already, yet, etc.Examples: * I have seen that movie twenty times. * I think I have met him once before. * There have been many earthquakes in California. * People have travelled to the Moon. * People have not travelled to Mars. * Have you read thebook yet? * Nobody has ever climbed that mountain. * A: Has there ever been a war in the United States?
B: Yes, there has been a war in the United States.How Do You Actually Use the Present Perfect?The concept of "unspecified time" can be very confusing to English learners. It is best to associate Present Perfect with the following topics:TOPIC 1 ExperienceYou can use the Present Perfect todescribe your experience. It is like saying, "I have the experience of..." You can also use this tense to say that you have never had a certain experience. The Present Perfect is NOT used to describe a specific event.Examples: * I have been to France.
This sentence means that you have had the experience of being in France. Maybe you have been there once, or several times. * I have been to Francethree times.
You can add the number of times at the end of the sentence. * I have never been to France.
This sentence means that you have not had the experience of going to France. * I think I have seen that movie before. * He has never traveled by train. * Joan has studied two foreign languages. * A: Have you ever met him?
B: No, I have not met him.TOPIC 2 Change Over TimeWe oftenuse the Present Perfect to talk about change that has happened over a period of time.Examples: * You have grown since the last time I saw you. * The government has become more interested in arts education. * Japanese has become one of the most popular courses at the university since the Asian studies program was established. * My English has really improved since I moved to Australia.TOPIC 3AccomplishmentsWe often use the Present Perfect to list the accomplishments of individuals and humanity. You cannot mention a specific time.Examples: * Man has walked on the Moon. * Our son has learned how to read. * Doctors have cured many deadly diseases. * Scientists have split the atom.TOPIC 4 An Uncompleted Action You Are ExpectingWe often use the Present Perfect to say that anaction that we expected has not happened. Using the Present Perfect suggests that we are still waiting for the action to happen.Examples: * James has not finished his homework yet. * Susan hasn't mastered Japanese, but she can communicate. * Bill has still not arrived. * The rain hasn't stopped.TOPIC 5 Multiple Actions at Different TimesWe also use the Present Perfect to talk about several...
