Hi, everyone.

大家好。

I’m Esther.

我是埃丝特。

In this video, I will introduce the future perfect tense.

在这个视频中，我将介绍将来完成时。

This tense is used to express an action in the future

这个时态用于表达将来

that will happen by a specific time in the future.

某个特定时间将发生的动作。

This tense can be a little difficult to understand but don't worry I will guide you through it

这种时态可能有点难以理解，但不用担心，我会引导您完成它，

so keep watching.

所以请继续观看。

The future perfect tense is used to express an action in the future

将来完成时用于表达将来

that will happen by a specific time in the future.

某个特定时间将发生的动作。

Let's look at some examples.

让我们看一些例子。

The first sentence says,

第一句话是：

‘The snow will have stopped by April.’

“雪到四月就会停。”

We start with the subject.

我们从主题开始。

In this case, ‘The snow’.

在这种情况下，“雪”。

Then, we follow with ‘will have’ and the past participle of the verb.

然后，我们跟上“will have”和动词的过去分词。

In this case, we used ‘stopped’ for the verb ‘stop’.

在这种情况下，我们使用“stopped”作为动词“stop”。

At the end of the sentence, you'll notice ‘by April’.

在句子的末尾，您会注意到“到四月”。

‘by April’ shows the specific time in the future when this action will have happened.

“by April”表示未来发生此操作的具体时间。

The next sentence says,

下一句是：

‘By the time he graduates, he will have completed five years of study.’

“到他毕业的时候，他已经完成了五年的学习。”

In this sentence,

在这句话中，

‘By the time he graduates’ or the specific time in the future.

“到他毕业的时候”或者未来的特定时间。

comes at the beginning of the sentence

出现在句子的开头

so ‘by’ plus ‘a time in the future’

，因此“by”加上“将来的某个时间”

can come at the end or it can come at the beginning.

可以出现在句子的末尾，也可以出现在开头。

‘By the time he graduates, he will have completed…’

“当他毕业时，他将完成……”

Again, you see ‘subject + will + have’ and the past participle of the verb.

再次，您会看到“主语+ will + have”和动词的过去分词。

In this case, ‘completed’.

在这种情况下，“完成”。

‘By the time he graduates, he will have completed five years of study.’

“当他毕业时，他将完成五年的学习。”

The next sentence says,

下一句话是：

‘Her arm will have fully healed by the summer.’

“到夏天，她的手臂就会完全康复。”

In this example, ‘by the summer’, the future specific time, comes at the end.

在此示例中，“到夏天”（未来的特定时间）出现在末尾。

By this time in the future, her ‘arm’, that's the subject, will have ‘healed’,

到了将来的这个时候，她的“手臂”（主语）将会“痊愈”（

the past participle.

过去分词）。

Here I put ‘fully’ just to show how much it will have healed.

在这里我用“完全”只是为了表明它已经治愈了多少。

I’m just adding an extra description.

我只是添加一个额外的描述。

The last sentence says,

最后一句说，

‘By next month, …’ so here we see ‘by’ and ‘the time’ at the beginning of the

“到下个月，……”所以我们在句子的开头看到“by”和“the time”

sentence.

。

‘you’, that's the subject.

‘你’，这是主语。

‘will have received’, there's the past participle.

“将收到”，是过去分词。

‘your promotion.’

“你的晋升。”

Again, ‘By next month you will have received your promotion.’

再说一次，“到下个月你就会收到晋升的消息。”

Let's move on.

让我们继续。

Now, let's talk about the negative form of the future perfect tense.

现在，我们来谈谈将来完成时的否定形式。

Here are some examples.

这里有些例子。

Let's take a look.

让我们来看看。

The first sentence says,

第一句话是：

‘I will not have graduated from university by July.’

“到七月我大学还没有毕业。”

First, I want to point out that at the end, I have the specific time in the future,

首先，我想指出的是，最后我有一个未来的具体时间，

‘byJuly’.

“byJuly”。

Now for the negative form, what I do is say, ‘subject’ and ‘will not have’,

现在对于否定形式，我所做的是说“主语”和“不会有”，

then we put the past participle of the verb.

然后我们加上动词的过去分词。

‘I will not have graduated from university by July.’

“到七月份我大学还没有毕业。”

The next sentence says,

下一句说：

‘Ollie and Max will not have spoken ...’

“Ollie 和 Max 不会说话……”

There it is again, ‘will not have’ and then the past participle of speak ...

又是“不会”，然后是 talk 的过去分词……

which is ‘spoken’.

即“说出”。

‘… before the plane leaves.’

“……在飞机起飞之前。”

Here, instead of the word ‘by’, we used ‘before’ to show a specific time in the

在这里，我们使用“before”代替“by”一词来表示未来的特定时间

future.

。

That's okay as well.

那也没关系。

The next sentence says,

下一句说，

‘You will not have eaten dinner by 6 p.m.’

“到下午 6 点你不会吃晚饭”。

Here, again, we've used ‘by 6 p.m.’ to show a time in the future.

在这里，我们再次使用“到下午 6 点”来表示将来的时间。

And again, you see ‘you will not have’ and then the past participle of eat which

再次，你会看到“你不会有”，然后是 eat 的过去分词

is ‘eaten’.

是“吃掉”。

The last sentence says, ‘By noon …’, there's the time again,

最后一句说，“到中午……”，又到了，

‘I will not have taken off to Japan.’

“我不会起飞去日本。”

‘taken’ is the past participle of ‘take’.

“taken”是“take”的过去分词。

Let's move on.

让我们继续。

Now, let's move on to how to form questions in the future perfect tense.

现在，让我们继续学习如何用将来完成时构成问题。

The first sentence here says,

这里的第一句话是

‘You will have gone to work by 10 a.m.’

“You will have gone to work by 10 am”

To turn this into a question, all we have to

要将其变成一个问题，我们所要做的

do is switch the order of the first two words.

就是交换前两个单词的顺序。

‘You will’ becomes ‘Will you’.

“你会”变成“你会吗”。

You'll notice that the rest of the question stays the same as the sentence.

您会注意到问题的其余部分与句子相同。

‘Will you have gone to work by 10 a.m.?’

“上午 10 点之前你会去上班吗？”

You can answer by saying, ‘Yes, I will have.’

你可以这样回答：“是的，我会的。”

or ‘No, I will have not.’

或“不，我不会。”

The next sentence says, ‘She will have woken up by noon.’

下一句话是：“她中午就会醒来。”

Again, to turn this into a question just switch the first two words.

同样，要将其变成一个问题，只需交换前两个词即可。

‘She will’ becomes ‘Will she’.

“她会”变成“她会”。

‘Will she have woken up by noon?’

“中午她会醒吗？”

Again, the rest of the sentence stays the same.

同样，句子的其余部分保持不变。

‘Will she have woken up by noon?’

“中午她会醒吗？”

To reply, you can say, ‘Yes, she will have.’

要回答，你可以说：“是的，她会的。”

or ‘No, she will have not.’

或者“不，她不会。”

Let's move on.

让我们继续。

Now, I'll talk about how to form ‘WH’ questions in the future perfect tense.

现在，我将讨论如何用将来完成时态构成“WH”问题。

If you notice on the board, each of these questions begins with the ‘WH’ word.

如果您在黑板上注意到，每个问题都以“WH”一词开头。

‘Where’, ‘what’, ‘who’, and ‘when’.

“哪里”、“什么”、“谁”和“何时”。

Then after each ‘WH’ word comes the word ‘will’.

然后在每个“WH”单词之后是“will”单词。

‘Where will’ ‘What will’

“哪里会”“什么会”

‘Who will’ and ‘When will’

“谁会”和“什么时候会”

So let's take a look at the first question.

所以让我们看一下第一个问题。

‘Where will’…’ then you add ‘the subject’.

“哪里会”……”然后添加“主题”。

In this case, ‘you’.

在这种情况下，是“你”。

And then, ‘have’ and after that the past participle of the verb.

然后是“have”，后面是动词的过去分词。

In this case, it's ‘traveled’.

在这种情况下，它是“旅行”的。

‘Where will you have traveled by December?’

“十二月之前你会去哪里旅行？”

I can answer by saying, ‘I will have traveled to Germany and Denmark.’

我可以回答说，“我会去德国和丹麦旅行。”

There are many possible answers here and this is just an example.

这里有很多可能的答案，这只是一个例子。

The next question says, ‘What will they have done …’

下一个问题是“他们会做什么……”“

‘done’ is the past participle of ‘do’.

done”是“do”的过去分词。

‘… by the end of the evening?’

“……晚上结束时？”

I can answer by saying, ‘They will have done their homework.’

我可以回答说：“他们会做足功课的。”

The next question says, ‘Who will she have interviewed by 5 p.m.?’

下一个问题是：“下午 5 点之前她会采访谁？”

Again, ‘who will’ + the subject ‘have’ and the past participle of the verb.

同样，“谁将”+主语“有”和动词的过去分词。

I can answer this question by saying,

我可以这样回答这个问题：

‘She will have interviewed the teachers by 5 p.m.’

“她将在下午 5 点之前采访老师”

And finally, ‘When will they have started to learn?’

，最后，“他们什么时候开始学习？”

One way to answer this question is to say,

回答这个问题的一种方法是说，

‘They will have started to learn in January.’

“他们将从一月份开始学习。”

Let's move on.

让我们继续。

Let's start this checkup for the future perfect tense.

让我们开始检查将来完成时态。

Take a look at the first sentence.

看看第一句话。

It says, ‘We _blank_ that book by tomorrow.’

它说，“我们明天之前_空白_那本书。”

The verb to use is ‘read’.

使用的动词是“读”。

Remember, in the future perfect tense, we start with the subject,

请记住，在将来完成时中，我们从主语开始，

and we have that here, ‘we’.

这里有“我们”。

Then say, ‘will have’ and the past participle of the verb.

然后说“will have”和动词的过去分词。

So here we need to say ‘will have’.

所以这里我们需要说“将会有”。

What is the past participle of ‘read’?

read的过去分词是什么？

The correct answer is ‘read’.

正确答案是“阅读”。

They're spelled the same, but they are pronounced differently.

它们的拼写相同，但发音不同。

‘We will have read that book by tomorrow.’

“到明天我们就会读完那本书了。”

The next sentence says, ‘She _blank_ the video by bedtime.’

下一句话是：“她在就寝时间之前_空白_视频。”

Here we have ‘not’ so I want you to try the negative form.

这里有“不”，所以我希望你尝试一下否定形式。

And the verb to try is ‘watch’.

尝试的动词是“观察”。

In the negative form, we start with the subject.

在否定形式中，我们从主语开始。

And instead of ‘will have’, we say ‘will not have’.

我们不说“将会有”，而说“不会有”。

‘She will not have …’ Then we need the past participle of the verb.

“她不会……​​”然后我们需要动词的过去分词。

In this case, it is ‘watched’.

在这种情况下，它被“观看”。

‘She will not have watched the video by bedtime.’

“她不会在睡觉前观看这段视频。”

Now find the mistake in the next sentence.

现在找出下一句中的错误。

‘Ryan will not have be to Cuba by summer.’

“到夏天瑞恩就不用去古巴了。”

This is the negative form because we have ‘will not have’.

这是否定形式，因为我们有“不会有”。

That's correct.

这是正确的。

But we need the past participle of ‘be’.

但我们需要“be”的过去分词。

So we need to change it to ‘been’.

所以我们需要将其更改为“曾经”。

‘Ryan will not have been to Cuba by summer.’

“到夏天瑞恩就不会去古巴了。”

The last sentence says, ‘I will have go to school by 8 30 a.m.’

最后一句说，“我将在上午 8 点 30 分之前去学校”。

Here, we have the affirmative, ‘will have’.

这里，我们有肯定句，“将会”。

But, uh oh, we forgot the past participle of ‘go’ which is ‘gone’.

但是，呃哦，我们忘记了“go”的过去分词，即“gone”。

‘I will have gone to school by 8 30 a.m.’

“我会在早上 8 点 30 分之前去学校”，

Great job, everybody.

大家干得好。

Let's move on.

让我们继续。

Good job, guys.

干得好，伙计们。

Now you have a better understanding of the future perfect tense.

现在您对将来完成时有了更好的理解。

I want you to keep studying and practicing this tense.

我希望你继续学习和练习这种时态。

I know studying English can be difficult, but I believe in you

我知道学习英语可能很困难，但我相信你

and I will guide you through it.
