We're now doing a checkup for the present perfect tense.
We're going to do a lot of practice questions,
For this checkup, we'll take a look at the present perfect tense.
Which describes an action that happened at
an unknown or indefinite time in the past.
Let's look at the first sentence.
The subject in this sentence is ‘she’.
For he/she/it, in this tense we say, ‘has’.
But remember we need to use the past participle of the verb.
‘read’ and ‘read’ are spelled the same.
The second sentence says, ‘They _blank_ visit China.’
‘visit’ is the verb that you want to use here.
For ‘I’, ‘you’, ‘we’ and ‘they’, we use ‘have’. Not ‘has’.
Now, what's the past participle of visit?
Next, ‘We _blank_ see that concert.’
Again, for ‘I’, ‘you’, we’ and ‘they’ – we use ‘have’.
‘We have’. Now, the past participle of ‘see’ is 'seen'.
Now, let's look for the mistake in the next sentence.
Take a look at the subject, ‘Rick’.
So instead of ‘have’, we need to change this to ‘has’.
‘Sally and I hasn't finished work.’
The subject in this sentence is ‘Sally’ and ‘I’.
That still sounds weird, right?
We have to change this to ‘have not’ or the contraction ‘haven't’.
And finally, ‘I did go to the doctor.’
Now this sentence makes sense, but it's not the present perfect tense.
Remember, we use ‘have’ for the subject, ‘I’.
What is the past participle of ‘go’?
Great job. Let's move on to the next checkup.
In this checkup, we'll talk about the present perfect tense
and how it can be used to describe an action that started in the past and is still true today.
The first sentence says, ‘I _blank_ known Carly since 1994.’
And we already have the past participle of the verb, ‘know’.
For ‘I’, ‘you’, ‘we’ and ‘they’, we use ‘have’ after the subject.
‘He has been here _blank_ 2 p.m.’
Now the first part is all there.
However, remember that for the present perfect tense,
we use ‘for’ or ‘since’ to talk about how long that action has been true.
In this case, we use ‘since’.
Because 2 p.m. is a specific period in time.
Next it says, ‘She _blank_ liked Tom since June.’
And we have the past participle of the verb ‘like’, which is 'liked'.
Again, we need ‘have’ or ‘has’.
Can you figure out which one you need?
‘She has liked Tom since June.’
Now, I want you to find a mistake in the next sentence.
‘I have worked here six months ago.’
‘I have worked’ - that's correct.
However, in the present perfect tense, we don't use ‘ago’.
This is talking about more the past.
We want to talk about ‘since’ or ‘for’ instead.
Now ‘six months’ is not a specific time. So we don't use ‘since’.
Instead, we talk about the duration. So we need ‘for’.
We'll say, ‘I have worked here for six months.’
Let's take a look at the next sentence.
‘Jen have a cold for two weeks.’
At first glance, this doesn't seem that wrong.
But wait a minute, ‘Jen has have a cold’?
We need the past participle of ‘have’.
‘Jen has had a cold for two weeks.’
And finally, ‘We haven't went home since Friday.’
‘We have… have not’. That's correct.
The contraction is ‘haven't’. ‘We haven't’.
Now the problem is, we have this verb ‘went’.
That's in the past simple tense.
We need the past participle of ‘go’.
‘We haven't gone home since Friday.’
Good job, guys. Let's move on to the next checkup.
In this checkup, we'll take a look at the present perfect tense.
And how it is used to describe an action that finished recently.
We'll be focusing on the words, ‘just’, ‘already’ and ‘recently’ to show this.
Let's take a look at the first sentence.
‘She has just _blank_ that book.’
And we're using the verb, ‘read’.
Remember, we take the subject, ‘she’.
And for ‘he’, ‘she’ and ‘it’, we say ‘has’.
Now we need the past participle of ‘read’.
‘She has just read that book.’
You'll notice I use the word, ‘just’ right before the past participle.
Next it says, ‘They have already’ and the verb is ‘wake up’.
If the subject is ‘he’, ‘she’, or ‘it’, we use ‘has’.
But if the subject is ‘I’, ‘you’, ‘we’ or ‘they’, we use ‘have’.
So that's correct. ‘They have’.
Also we have the word ‘already’ here to show that it happened recently
We need the past participle of ‘wake up’,
‘We have recently _blank_ work.’
And we have the word 'recently' to show when the action finished.
And now we need to find the past participle of the verb ‘finish’.
‘We have recently finished, -ed, work.’
Now try to find the mistake in the next sentence.
This sounds a little strange, right?
That's because ‘just’ needs to come before the verb.
Therefore, the answer is ‘Morty has just eaten.’
The next sentence says, ‘Karen has recently be sick.’
Now we need the past participle of the verb.
‘be’ is our verb and the past participle of ‘be’ is ‘been’.
‘Karen has recently been sick.’
And finally, ‘I have gone already to the dentist.’
This is similar to another question we looked at just before.
‘I have gone already to the dentist.’
The placement of ‘already’ is a little awkward.
So we can say, ‘I have already gone.’
So we can put ‘already’ before the verb,
‘I have already gone to the dentist’
Or we can put this at the end,
‘I have gone to the dentist already.’
That is the end of the checkup.
You just learned about the present perfect tense.
There was a lot to learn, but you did a wonderful job.
I know that It's hard, but you will get better with time, effort and practice.
