1. CUNG CẤP GIÁO VIÊN NƯỚC NGOÀI – PRESENT

[has/have + past participle]
Examples:
 You have seenthat movie many times.
 Have you seenthat movie many times?
 You have not seenthat movie many times.
Complete List of Present Perfect Forms

2. USE 1 Unspecified Time Before Now
We 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 seenthat movie twenty times.
 I think I have met him once before.
 There have been many earthquakes in California.
 People have traveled to the Moon.
 People have not traveled to Mars.
 Have you read the bookyet?
 Nobodyhas 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 conceptof "unspecified time" can be very confusing to English learners. It is
best to associate Present Perfect with the following topics:
TOPIC 1 Experience
You can use the Present Perfect to describe 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 meansthat you havehad the experience of being in France.
Maybeyou have been there once, or several times.

3.  I have been to France three times.
You can add the numberof times at the end of the sentence.
 I have never been to France.
This sentence meansthat you havenot had the experience of going to
France.
 I think I have seenthat 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 Time
We often use the Present Perfect to talk about change that has happened over a
period of time.
Examples:
 You have grownsince 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 3 Accomplishments
We often use the Present Perfect to list the accomplishments of individuals and
humanity. You cannot mention a specific time.
Examples:
 Man has walkedon the Moon.
 Our sonhas learned how to read.
 Doctors have cured many deadly diseases.
 Scientists have split the atom.
TOPIC 4 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 the action
to happen.

4. Examples:
 James has not finished his homework yet.
 Susan hasn't masteredJapanese, but she can communicate.
 Bill has still not arrived.
 The rain hasn't stopped.
TOPIC 5 Multiple Actions at Different Times
We also use the Present Perfect to talk about several different actions which have
occurred in the pastat different times. Present Perfect suggests the process is not
complete and more actions are possible.
Examples:
 The army has attackedthat city five times.
 I have had four quizzes and five tests so far this semester.
 We have had many major problems while working on this project.
 She has talked to several specialists about her problem, but nobodyknows
why she is sick.
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. Remember, the exact time the action happened is not
important.
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.
Examples:
 Have you been to Mexico in the lastyear?
 I have seenthat movie six times in the last month.

5.  They have had three tests in the lastweek.
 She graduated from university less than three years ago. She has workedfor
three different companies so far.
 My car has brokendown three times this week.
NOTICE
"Last year" and "in the last year" are very different in meaning. "Last year" means
the year before now, and it is considered a specific time which requires Simple
Past. "In the last year" means from 365 days ago until now. It is not considered a
specific time, so it requires Present Perfect.
Examples:
 I went to Mexico last year.
I went to Mexico in the calendaryear before this one.
 I have been to Mexico in the lastyear.
I have been to Mexico at least once at some point between 365 daysago and
now.
USE 2 Duration From the PastUntil Now (Non-Continuous Verbs)
With Non-Continuous Verbs and non-continuous uses of Mixed Verbs, we use the
Present Perfect to show that something started in the past and has continued up
until now. "For five minutes," "for two weeks," and "since Tuesday" are all
durations which can be used with the Present Perfect.
Examples:
 I have had a cold for two weeks.
 She has been in England for six months.
 Mary has loved chocolate since she was a little girl.
Although the above use of Present Perfect is normally limited to Non-Continuous
Verbs and non-continuous uses of Mixed Verbs, the words "live," "work," "teach,"
and "study" are sometimes used in this way even though they are NOT Non-
Continuous Verbs.

6. 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 movie one time.
 Have you only seen that movie one time?
ACTIVE / PASSIVE
Examples:
 Many tourists have visited that castle. Active
 That castle has been visited by many tourists. Passive
