Today we are going to learn about the present perfect tense.

未來簡單式

We'll cover how to form it, how to ask and answer questions, and

我們會講到它的形成方式、問答句，還有

Let's start with the form of present perfect.

我們先從現在完成式的結構開始。

You just need a subject, the verb have or has and the past participle.

你只需要一個主詞，加上 have 或 has，還有過去分詞。

I have eaten breakfast every day this week.

For regular verbs, the past participle is the same as the past simple form.

對於規則動詞，過去分詞跟過去式是一樣的。

You just have to add ed to the base verb.

Do I use this rule for irregular verbs too?

不規則動詞也要用這個規則嗎？

You'll need to memorize the past participle forms of irregular verbs just like you did for the past simple tense.

你必須像記過去式一樣，去記住不規則動詞的過去分詞形式。

如果你還沒看過我們過去式的教學，快去看看吧。

I have been to many countries with my family.

我今天已經做完我所有的家事了。

Now that we understand how to form present perfect, let's take a look at when to use it.

既然我們瞭解了現在完成式的構成方式，接下來我們就來看看什麼時候要用它。

The easiest way to use present perfect is to think about time frames.

用現在完成式最簡單的方式，就是去想時間範圍。

This means the action happened in a time frame that started but is not finished yet.

這表示這個動作發生在一個已經開始但還沒結束的時間範圍內。

The time frame in this example is my life.

這個例子的時間範圍是我的生命。

We often use present perfect for life experience.

我們常常用現在完成式來表達生活經驗。

For this reason, can you name some other time frames that started but are not finished today, this week, this month, this year?

基於這個原因，你能說出其他已經開始但還沒結束的時間範圍嗎？像是今天、這週、這個月、今年？

We can use present perfect for all of these.

這些我們都可以用現在完成式。

But if the time frame is finished, we can't use present perfect.

但是如果時間範圍已經結束了，我們就不能用現在完成式。

Use past simple for finished times like yesterday, last month, and last year.

像昨天、上個月、去年這些已經結束的時間，我們就用過去式。

I noticed the word never in the last example.

我注意到上一個例子裡有 "never" 這個字。

我們什麼時候會用到 ever 或 never 呢？

We use ever and never only to talk about the time frame of life experiences, not for shorter time frames.

ever 和 never 我們只用來談論生活經驗的時間範圍，而不是用在比較短的時間範圍。

Use ever to ask if something has happened at least once and use never if the action has not happened at least once.

ever 我們用來問某件事有沒有至少發生過一次，而 never 則是用來表示某個動作從來沒有發生過。

For example, have you ever gone to a theme park?

舉例來說，你有沒有去過主題樂園？

I have written three books of short stories for my kids.

我寫了三本短篇故事書給我的孩子們。

I have never climbed a mountain, but I'd love to.

我從來沒爬過山，但我很想去。

Now let's talk about how to make negative sentences.

只要在 have 或 has 後面加上 not。

Have not becomes haven't and has not becomes hasn't.

Have not 會變成 haven't，has not 會變成 hasn't。

Using present perfect, start the sentence with have or has.

用現在完成式，句子的開頭就用 have 或 has。

Then add the subject and past participle.

舉例來說，你有讀過這本書嗎？

Another way to use present perfect is with these three words.

現在完成式還可以用這三個詞來表達。

The word just means something happened very recently.

Just 這個詞的意思是事情才剛發生不久。

For example, I have just finished my house chores.

We use already if something happened earlier than expected or to emphasize that it happened.

我們用 already 來表示事情比預期早發生，或是強調事情已經發生了。

我們去看那部新的喜劇電影吧。

The word yet is used in questions and negatives and means something hasn't happened up to now, but

yet 這個詞用在問句和否定句，意思是事情到目前還沒發生，

The present perfect is formed with subject, have or has and the past participle.

現在完成式是由主詞、have 或 has，以及過去分詞組成的。

And you can use it to talk life experiences, actions in unfinished time frames.

你也可以用它來談論生活經驗，或是在未結束的時間範圍內發生的動作。
