We're now doing a checkup for the present perfect tense.

to 不定詞

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.

For he/she/it, in this tense we say, 'has'.

But remember we need to use the past participle of the verb.

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?

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.

So instead of 'have', we need to change this to 'has'.

The subject in this sentence is 'Sally' and 'I'.

We have to change this to 'have not' or the contraction 'haven't'.

Now this sentence makes sense, but it's not the present perfect tense.

Remember, we use 'have' for the subject, 'I'.

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.

However, remember that for the present perfect tense,

we use 'for' or 'since' to talk about how long that action has been true.

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'.

Now, I want you to find a mistake in the next sentence.

However, in the present perfect tense, we don't use 'ago'.

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.'

At first glance, this doesn't seem that wrong.

But wait a minute, 'Jen has have a cold'?

And finally, 'We haven't went home since Friday.'
