在本视频中，

我将讨论两个相似

且有时令人困惑的英语表达

expressions – ‘since’ and ‘for’.

“since”和“for”。

These two time expressions are commonly confused in English.

这两个时间表达在英语中经常被混淆。

But after watching this video, you'll have a good understanding of the difference and when to use these words.

但观看此视频后，

您将很好地理解这些词的区别

以及何时使用这些词。

Let’s get started.

让我们开始吧。

Let’s start with ‘since’

让我们从“自从”开始。

‘since’ shows when a past action first started.

“since”表示过去的动作第一次开始的时间。

We always need a starting point with ‘since’

我们总是需要一个带有“since”的起点，

so when you use ‘since’, you always need a specific time expression.

因此当您使用“since”时，

您总是需要一个特定的时间表达式。

Let's take a look at some example sentences.

让我们看一些例句。

The first sentence says,

第一句话是：

‘I have been working since 8 o'clock this morning.’

“我从今天早上 8 点开始工作。”

You'll notice that the specific time expression comes after ‘since’.

您会注意到特定时间表达式位于“since”之后。

And it shows when this person started working.

它显示了这个人何时开始工作。

The next sentence says,

下一句话是：

‘She has been on a diet since August.’

“她从八月起就开始节食了。”

The specific time expression here is August

这里的具体时间表达是 August

and it comes after ‘since’.

，位于“since”之后。

It shows when she started dieting.

它显示了她何时开始节食。

Okay, now, I will talk about ‘for’.

好吧，现在我要谈谈“为了”。

We use ‘for’ to express a length of time in English.

我们在英语中使用“for”来表达时间长度。

It is used to express duration or how long something has happened.

它用于表达持续时间

或某件事发生了多长时间。

Let's take a look at some examples.

让我们看一些例子。

The first sentence says,

第一句话是：

‘I have been working for five hours.’

“我已经工作了五个小时。”

In this case, we have a duration five hours

在本例中，

我们的持续时间为五个小时

and it comes after ‘for’.

，它位于“for”之后。

The next sentence says,

下一句话是：

‘She has been on a diet for three months’.

“她已经节食三个月了”。

Again, we have three months which shows the duration

同样，我们有三个月的

时间来显示

- how long she has been on a diet.

她节食的持续时间。

Again, notice it comes after the word ‘for’.

再次注意，它出现在“for”一词之后。

Now, let's do a checkup.

现在，我们来做个检查。

In this conversation, there are two sentences.

这段对话中

有两句话。

In one of the sentences, we should use ‘since’

在其中一个句子中，

我们应该使用“since”

and in the other we should use ‘for’.

，而在另一个句子中，我们应该使用“for”。

Take a moment to think about where we use ‘since’ and ‘for’.

花点时间思考一下我们在哪里使用“since”和“for”。

‘A' says,

“A”说，“你 _blank_ 2008 年一直在这里工作吗？”

‘Have you been working here _blank_ 2008?’

You'll notice the specific time expression ‘2008’.

您会注意到特定的时间表达式“2008”。

Remember, when we use a specific time expression,

请记住，当我们使用特定时间表达式时，

we put ‘since’ before the expression.

我们会在表达式之前添加“since”。

So ‘A’ says,

所以“A”说：“你从 2008 年起就一直在这里工作吗？”

‘Have you been working here since 2008?’

‘B’ says, ‘No, I’ve only been working here _blank_ two weeks.’

“B”说：“不，我只在这里工作_空白_两周。”

‘two weeks’ is a duration.

“两周”是一个持续时间。

It shows how long this action has been happening.

它显示了此操作已经发生了多长时间。

So the best answer here is ‘for’.

所以这里最好的答案是“为了”。

‘No, I’ve only been working here for two weeks.’

“不，我才在这里工作两周。”

So let's take a look at the whole conversation.

那么我们来回顾一下整个对话。

‘A’ says,

“A”说：“你从 2008 年起就在这里工作了吗？”

‘Have you been working here since 2008?’

“B”说：“不，我只在这里工作了两周。”

And ‘B’ says, ‘No, I’ve only been working here for two weeks.’

Now you know the difference between ‘since’ and ‘for’.

现在您知道“因为”和“因为”之间的区别了。

Be sure to practice these two time expressions.

一定要练习这两个时间表达。

They're very important to properly express time and duration in English.

它们对于

用英语正确表达时间和持续时间非常重要。
