歡迎來到視頻

In this video, we'll be looking at the present perfect tense

在這段視頻中，我們將關注現在的完成時態。

First we're going to focus on the form,

首先我們要關注的是形式。

or the actual words that you need to use to form the tense

或實際需要用到的詞來構成時態

Now, the present perfect is a compound tense

現在，現在完成時是一個複合時態。

Meaning that you need two verbs together

意思是說，你需要兩個動詞一起

to...aahhh...form it

以......啊啊......形成它。

Aaahhh, first you have an auxiliary verb

啊啊啊，首先你有一個助動詞。

which is followed by the main verb

後面是主動詞

In the present perfect

在現在的完美

The auxiliary verb is 'have'

助動詞是'有'。

Now, this is important, so pay attention!

現在，這很重要，所以要注意!

The auxiliary verb must change form to agree with the subject

助動詞必須改變形式才能與主語一致

Then we have the main verb

然後，我們有主動詞

which is in the past participle form

這是在過去分詞形式

For example, I could say 'I have done'

例如，我可以說 "我已經做了

Or, 'he has done'

或者，'他做了'。

Okay, now let's take a look at the form

好了，現在讓我們來看看這個表格。

for statements- both positive and negative

語句--包括正面和負面的語句

in a positive statement you have the subject

正話反說

plus the auxiliary verb, and then the main verb

加助動詞，再加主動詞

For example,...

比如說，...

Now, for a negative statement

現在，對於一個否定的說法

you need to put the negative particle

你需要把負粒子

between the auxiliary verb

在助動詞之間

and the main verb

和主動詞

Now, the...uhhh...not

現在，這個......呃......不對。

can also be contracted to 'haven't'

亦可作'未'字。

or 'hasn't'

或 "沒有

Okay...now let's take a look at questions

好了......現在我們來看看問題吧

both positive and negative

正反兩方面

The main thing about questions is you have to switch the order

關於問題的主要內容是你必須切換順序。

of the subject and the auxiliary verb

的主語和助動詞

So the sentence now begins with the auxiliary verb

所以現在的句子是以助動詞開始的

plus the subject

加上主題

Now, just as in the negative statement

現在，就像在否定的聲明中

in a negative question, the negative particle 'not'

麼

goes after the auxiliary verb

在助動詞之後

So, we have....

所以，我們有...

Now, in the question form

現在，以問題的形式

It is pretty much always contracted

它是相當多的總是收縮

to 'n't',...'haven't'

到'沒有'，......'沒有'

because 'have not you done?' sounds a little bit awkward

因為 "你沒做嗎？"聽起來有點彆扭

it's too long. So everybody says 'haven't you done?'

太長了。所以大家都說 "你還沒做嗎？
