Hello, English learners（学习者）, and welcome to EnglishPod. My name is Marco. And I'm Erica. Hey, Erica. Who are you today? Marco, I am doing really well, and I'm really looking forward（向前） to today's lesson.

  Well, so am I, because here at EnglishPod, we're giving you real English. Everyday（每天的） English. Exactly（确切地）. English that you hear in movies or in TV shows. This is English people actually（实际上） use. So, Erica, what is our topic for today?

  Well, today we're talking about computer viruses（[微]病毒）. Perfect（完成式）. So, I think it's time for us to take a look（看） at our preview（预演）. Okay（好）, today we've got two words to preview（预演）. The first word is virus. Virus.

  Virus. Virus. So, if your computer has a computer virus, it means（意味） your computer is sick, right? Actually, a computer virus is a program（节目单） that is designed to harm（损害） or to damage（损害） your computer. Oh, I see. Okay.

  Well, thank you for being so technical（技术的）. That's the technical explanation（解释）. Okay, let's take a look at our second word for our preview today, and that would be froze（冻）. Froze. Froze. Froze.

  Froze. So, if your computer froze, it means that... Your computer stopped working（使工作）. Your applications（请求） or your programs（节目单） stopped working（使工作）, and you just can't do anything. Your computer is broken. Okay, great.

  So, let's listen to our dialogue. It's going to be a little bit（一点） fast, but... Don't worry（ 担忧） if you don't understand everything. At the end of this podcast, you'll understand everything. Perfect. Let's listen.

  Oh, great. The stupid（ 愚蠢的） computer froze（冻） again. That's the third time today. Hey, Samuel. Can you come take a look at my PC? It's acting（行动） up again.

  It must have a virus or something. Just give me a second. I'll be right up. I ran a virus scan（细看） on your computer, and it turns out that you have a lot of infected（被感染的） files（文件）. But I'm quite careful（仔细的） when I'm browsing（吃草） the internet. I have no idea how I could have picked（ 拾起） up a virus（[微]病毒）.

  Well, you have to make sure their antivirus software（ 软件） is updated（更新） regularly（定期地）. Yours（你（们）的东西） wasn't up to date. That's probably what was causing（造成） your problems. Okay, anything else? Yeah, try not to kick（ 踢） or hit（打） the computer. Um, yeah, sorry about that.

  Well, I completely（十分） understand this guy（家伙）. When my computer freezes, I kick it and punch（冲出） it and do everything to it. Well, I hope you don't punch it too hard, Marco. Well, it's still working, so it's all（ 全部） right. Okay. All right, let's take a look at our language takeaway（外卖食品）.

  In today's language takeaway, we have two words. The first word for today is "infected file." Infected（传染） file（文件）. Infected file. Infected file. And what is an infected file?

  An infected file is a file in your computer that has a virus in it. Ah（啊）, perfect. That's really clear（清晰的）. What is our second word for the language takeaway today? Our second word is "not up to date." Not up to date.

  Not up to date. And what is it when something is not up to date? It means it doesn't have all the most recent（新近的） information. Okay, perfect. Now（现在） let's listen to some examples.
