Practice Present Perfect Tense | English Grammar Course #6 | CheckUp

Hi, everyone. I'm Esther.

大家好。我是埃丝特。

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

我们现在正在检查现在完成时。

We're going to do a lot of practice questions,

我们将做很多练习题，

so let's get started.

所以让我们开始吧。

For this checkup, we'll take a look at the present perfect tense.

在这次检查中，

我们将看一下现在完成时。

Which describes an action that happened at

它描述了

an unknown or indefinite time in the past.

在过去未知或不确定的时间 发生的动作

Let's look at the first sentence.

。 我们看第一句话。

‘She _blank_ read that book.’

“她_空白_读了那本书。”

The subject in this sentence is ‘she’.

这句话的主语是“她”。

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

对于他/她/它，我们用这种时态说“有”。

‘She has’.

'她有'。

Now, take a look at the verb.

现在，看一下动词。

It looks like ‘read’.

看起来像“读”。

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

但请记住我们需要使用动词的过去分词。

So It's actually ‘read’.

所以它实际上是“读”。

‘read’ and ‘read’ are spelled the same.

“读”和“读”拼写相同。

‘She has read that book.’

“她读过那本书。”

The second sentence says, ‘They _blank_ visit China.’

第二句话是：

“他们_空白_访问中国。”

‘visit’ is the verb that you want to use here.

“访问”是您要在此处使用的动词。

For ‘I’, ‘you’, ‘we’ and ‘they’, we use ‘have’. Not ‘has’.

对于“我”、“你”、“我们”和“他们”，

我们使用“有”。不是‘有’。

‘They have’

“他们有”

Now, what's the past participle of visit?

现在，visit 的过去分词是什么？

The answer is ‘visited’.

答案是“访问过”。

‘They have visited China.’

“他们访问过中国。”

Next, ‘We _blank_ see that concert.’

接下来，“我们_空白_看那场音乐会。”

Again, for ‘I’, ‘you’, we’ and ‘they’ – we use ‘have’.

同样，对于“我”、“你”、“我们”和“他们”——我们使用“有”。

‘We have’. Now, the past participle of ‘see’ is 'seen'.

'我们有'。

现在，“see”的过去分词是“seen”。

‘We have seen that concert.’

“我们看过那场音乐会。”

Now, let's look for the mistake in the next sentence.

现在，我们来看看下一句中的错误。

‘Rick have been to Cuba.’

“里克去过古巴。”

Take a look at the subject, ‘Rick’.

看看主题“Rick”。瑞克是一个“他”。

Rick is a ‘he’.

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

因此，我们需要将其更改为“has”，而不是“have”。

‘Rick has been to Cuba.’

“里克去过古巴。”

‘Sally and I hasn't finished work.’

“莎莉和我还没有完成工作。”

The subject in this sentence is ‘Sally’ and ‘I’.

这句话的主语是“莎莉”和“我”。

The pronoun for that is ‘we’.

其代词是“我们”。

‘We hasn't finished work.’

“我们还没有完成工作。”

That still sounds weird, right?

这听起来还是很奇怪，对吧？

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

我们必须将其更改为“have not”

或缩写“have not”。

And finally, ‘I did go to the doctor.’

最后，“我确实去看了医生。”

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

现在这句话是有道理的，

但它不是现在完成时。

We have to change it.

我们必须改变它。

Remember, we use ‘have’ for the subject, ‘I’.

请记住，我们使用“have”作为主语“I”。

But we're not done.

但我们还没有完成。

What is the past participle of ‘go’?

go的过去分词是什么？

It is ‘gone’.

它已经‘消失’了。

‘I have gone to the doctor.’

“我已经去看医生了。”

Great job. Let's move on to the next checkup.

做得好。让我们继续进行下一次检查。

In this checkup, we'll talk about the present perfect tense

在这次检查中，

我们将讨论现在完成时

and how it can be used to describe an action that started in the past and is still true today.

以及如何使用它来描述

从过去开始并且今天仍然正确的动作。

The first sentence says, ‘I _blank_ known Carly since 1994.’

第一句话是：

“我从 1994 年就_空白_认识卡莉。”

The subject is ‘I’.

主语是“我”。

And we already have the past participle of the verb, ‘know’.

我们已经有了动词“知道”的过去分词。

Which is ‘known’.

这就是“已知”。

What are we missing?

我们缺少什么？

The correct answer is ‘have’.

正确答案是“有”。

For ‘I’, ‘you’, ‘we’ and ‘they’, we use ‘have’ after the subject.

对于“我”、“你”、“我们”和“他们”，我们在主语后使用“have”。

The next sentence says,

下一句说，

‘He has been here _blank_ 2 p.m.’

“他下午 2 点_空白_一直在这儿”

Now the first part is all there.

现在第一部分就到了。

‘He has been’.

'他一直'。

However, remember that for the present perfect tense,

但是，请记住，对于现在完成时，

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

我们使用“for”或“since”来谈论

该动作已经持续了多长时间。

In this case, we use ‘since’.

在这种情况下，我们使用“自”。

Because 2 p.m. is a specific period in time.

因为下午2点是一个特定的时间段。

Next it says, ‘She _blank_ liked Tom since June.’

接下来，它说，“从六月起，她_空白_喜欢汤姆。”

The subject is ‘she’.

主语是“她”。

And we have the past participle of the verb ‘like’, which is 'liked'.

我们还有动词“like”的过去分词，

即“liked”。

What are we missing?

我们缺少什么？

Again, we need ‘have’ or ‘has’.

同样，我们需要“有”或“有”。

因为主语是“她”……

Because the subject is ‘she’...

Can you figure out which one you need?

你能弄清楚你需要哪一个吗？

The correct answer is ‘has’.

正确答案是“有”。

‘She has liked Tom since June.’

“她从六月起就喜欢汤姆了。”

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

现在，我想让你找出下一句话中的错误。

‘I have worked here six months ago.’

“六个月前我在这里工作过。”

Can you find a mistake here?

你能发现这里有错误吗？

‘I have worked’ - that's correct.

“我已经工作了”——这是正确的。

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

然而，在现在完成时中，我们不使用“ago”。

This is talking about more the past.

这更多是在谈论过去。

We want to talk about ‘since’ or ‘for’ instead.

我们想谈论“因为”或“因为”。

Now ‘six months’ is not a specific time. So we don't use ‘since’.

现在的“六个月”并不是一个具体的时间。

所以我们不使用“自从”。

Instead, we talk about the duration. So we need ‘for’.

相反，我们谈论持续时间。

所以我们需要“为”。

We'll say, ‘I have worked here for six months.’

我们会说，“我在这里工作了六个月。”

Let's take a look at the next sentence.

我们再看下一句话。

‘Jen have a cold for two weeks.’

“珍感冒了两周了。”

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

乍一看，这似乎并没有那么错误。

But remember, Jen is a ‘she’.

但请记住，Jen 是一个“她”。

So we need ‘has’.

所以我们需要“有”。 “珍有”。

‘Jen has’.

But wait a minute, ‘Jen has have a cold’?

但是等一下，“Jen 感冒了”？

That's not right either.

这也是不对的。

We need the past participle of ‘have’.

我们需要“have”的过去分词。

What is the past participle?

过去分词是什么？

The correct answer is ‘had’.

正确答案是“有”。

‘Jen has had a cold for two weeks.’

“珍已经感冒两周了。”

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

最后，

“我们从周五起就没有回家过。”

This one is a little tricky.

这个有点棘手。

The subject is ‘we’.

主语是“我们”。

‘We have... have not’. That's correct.

“我们有……没有”。这是正确的。

The contraction is ‘haven't’. ‘We haven't’.

缩写是“没有”。 “我们没有”。

Now the problem is, we have this verb ‘went’.

现在的问题是，我们有这个动词“去”。

That's in the past simple tense.

这是过去简单时态。

We need the past participle of ‘go’.

我们需要“go”的过去分词。

The correct answer is ‘gone’.

正确答案是“消失”。

‘We haven't gone home since Friday.’

“自从周五以来我们就没有回家过。”

Good job, guys. Let's move on to the next checkup.

干得好，伙计们。让我们继续进行下一次检查。

In this checkup, we'll take a look at the present perfect tense.

在这次检查中，我们将看看现在完成时。

And how it is used to describe an action that finished recently.

以及如何使用它来描述最近完成的动作。

We'll be focusing on the words, ‘just’, ‘already’ and ‘recently’ to show this.

我们将重点关注“刚刚”、“已经”和“最近”等词

来展示这一点。

Let's take a look at the first sentence.

我们看一下第一句话。

‘She has just _blank_ that book.’

“她那本书只是_空白_。”

And we're using the verb, ‘read’.

我们使用动词“读”。

请记住，我们采用的主题是“她”。

Remember, we take the subject, ‘she’.

And for ‘he’, ‘she’ and ‘it’, we say ‘has’.

对于“他”、“她”和“它”，我们说“有”。

So that's correct.

所以这是正确的。

Now we need the past participle of ‘read’.

现在我们需要“read”的过去分词。

And that is ‘read’.

这就是“读”。

‘She has just read that book.’

“她刚刚读过那本书。”

You'll notice I use the word, ‘just’ right before the past participle.

你会注意到我 在过去分词之前

使用了“just”这个词

Next it says, ‘They have already’ and the verb is ‘wake up’.

。 接下来它说，“他们已经”，动词是“醒来”。

If the subject is ‘he’, ‘she’, or ‘it’, we use ‘has’.

如果主语是“他”、“她”或“它”，我们使用“has”。

But if the subject is ‘I’, ‘you’, ‘we’ or ‘they’, we use ‘have’.

但如果主语是“我”、“你”、“我们”或“他们”，我们就使用“have”。

So that's correct. ‘They have’.

所以这是正确的。 '他们有'。

Also we have the word ‘already’ here to show that it happened recently

此外，我们这里有“已经”一词

来表明它最近发生

or that it finished recently.

或最近完成。

Now the verb is ‘wake up’.

现在动词是“醒来”。

We need the past participle of ‘wake up’,

我们需要“wake up”的过去分词，

and that is ‘woken up’.

那就是“wake up”。

So the answer is,

所以答案是，

‘They have already woken up.’

“他们已经醒了。”

The next sentence says,

下一句话是：

‘We have recently _blank_ work.’

“我们最近有_空白_工作。”

动词是“完成”。

And the verb is ‘finish’.

‘We have’, that's correct.

“我们有”，这是正确的。

我们有“最近”这个词

And we have the word 'recently' to show when the action finished.

来显示动作何时完成。

现在我们需要找到动词“finish”的过去分词。

And now we need to find the past participle of the verb ‘finish’.

The correct answer is.

正确答案是。

‘We have recently finished, -ed, work.’

“我们最近完成了工作。”

Now try to find the mistake in the next sentence.

现在尝试找出下一句话中的错误。

‘Morty has eaten just.’

“莫蒂刚刚吃过饭。”

This sounds a little strange, right?

这听起来有点奇怪，对吧？

That's because ‘just’ needs to come before the verb.

这是因为“just”需要出现在动词之前。

Therefore, the answer is ‘Morty has just eaten.’

因此，答案是“莫蒂刚刚吃过饭。”

The next sentence says, ‘Karen has recently be sick.’

下一句话是：

“凯伦最近生病了。”

Karen is a ‘she’.

凯伦是一个“她”。

So ‘has’ is correct.

所以“有”是正确的。

And there we have ‘recently’.

我们有“最近”。

Now we need the past participle of the verb.

现在我们需要动词的过去分词。

‘be’ is our verb and the past participle of ‘be’ is ‘been’.

“be”是我们的动词，“be”的过去分词是“been”。

‘Karen has recently been sick.’

“凯伦最近生病了。”

And finally, ‘I have gone already to the dentist.’

最后，“我已经去看牙医了。”

This is similar to another question we looked at just before.

这与我们之前讨论过的另一个问题类似。

‘I have gone already to the dentist.’

“我已经去看牙医了。”

The placement of ‘already’ is a little awkward.

“已经”的位置有点尴尬。

So we can say, ‘I have already gone.’

所以我们可以说：“我已经走了。”

So we can put ‘already’ before the verb,

所以我们可以在动词前加上“已经”，

‘I have already gone to the dentist’

“我已经去看牙医了”，

Or we can put this at the end,

或者我们可以把它放在最后，

‘I have gone to the dentist already.’

“我已经去看牙医了。”

Both of those are correct.

这两点都是正确的。

Now, good job.

现在，干得好。

That is the end of the checkup.

至此，检查结束。

Let's move on.

让我们继续。

Excellent job, everyone.
