Sarah: Hello, everyone. Today, we are going to talk about the present perfect continuous tense. It confused you ear lier, but we'll fix that today.
Sarah: 嗨，大家好。今天，我们谈谈什么是现在完成进行时。之前它令你困惑不解，今天我们就来搞定它。
Veronica: Right Sarah. Tenses are really confusing.
Veronica: 好的，Sarah。时态真的很让人困惑。
Sarah: To begin with, there are two basic functions of the present perfect continuous tense. The first is that we use this tense to to talk about an action that started in the past and stopped recently.
Sarah: 首先，现在完成进行时有两种基本用法，第一种：我们用这个时态讨论一个起始于过去，最近才停止的动作。
Veronica: That's absolutely right. For example: I'm exhausted because I've been running.
Veronica: 完全正确。比如：一直在跑步，我累了。
Sarah: Correct! You're definitely taking good care of your health Veronica.
Sarah: 对!你照顾自己的身体照顾得很好。
Veronica: No doubt! The second function of the present perfect continuous tense is to talk about an action that started in the past and it is still happening.
Veronica: 毫无疑问!第二种：谈论一个起始于过去，但是现在仍在发生的动作。
Sarah: For instance: you've been watching this lesson for the past one minute.
Sarah: 比如说：你看电视看了一分钟了。
Veronica: Alright! So it's easy. Present perfect continuous tense is used when we're talking about things that are still ongoing, or have just stopped.
Veronica: 好了!太简单了。我们想说那种正在进行的或者才刚刚停止的动作，就用现在完成进行时时态。
Sarah: Yeah! You typically use ‘have been', or ‘has been', and the continuous form of verb, usually ending with an ‘ing'. Like in “He's been eating for one hour”.
Sarah: 对啦!用“have been”和“has been”，动词要用进行时态，通常以“ing”结尾。比如：他吃饭吃了一个小时了。
Veronica: One hour? Wow! He must be such a glutton! Let's listen to some conversations now Sarah.
Veronica: 一个小时?哇!他一定是个大胃王!现在我们听一下对话吧，Sarah。
Sarah: Sure Veronica!
Sarah: 好的，Veronica!
