老师：Hello everyone. Welcome to Unit 3, Online Tours. When you come across the topic online tours, what can you think of? You may ask some questions with the given who words. For example, what are online tours? Why should we take online tours? When and where can we have online tours? Who should we take online tours together with? And how can we take online tours? Actually, you can ask more questions, and I think after learning this unit, you can get the answers to your questions.
老师：Now I'd like to ask you a question. What do we need most to have online tours? Please think about the question, perhaps the machine in this picture. Our friends Eddie and hobo, they are also talking about it. Let's watch and answer. What do they think the machine looks like? Are you ready? Let's go.
学生：Have you used it before, Eddie? No, never. It looks like a TV. I agree. Look, this program began an hour ago. Boring, right? Where's the remote control? Here it is. Let's change the channel.
老师：OK, so much for the video. I think it's not so difficult for us to get their words. Hobo said, it looks like a TV. And Eddie replied, I agree. That means I agree with you. So we can find out. They both think the machine looks like a TV. Now you can open your books and try to read their dialogue and answer two more questions. No. 1, what do they think about the program and why? No. 2, what will they do with the program? Here, pay attention to the word program. Okay, let's do it. Have you used this before, Eddie? No.
学生：Never. It looks like a TV. I agree. Look, this program began an hour ago. Boring, right? Where's the remote control? Here it is. Let's change the channel.
老师：OK, let's come to question 1. What do they think about the program and why? I think picture 3 can help us. We can find words in it. They think the program is boring. It began an hour ago. What's the meaning of the sentence? It began an hour ago. Maybe we can rewrite it in two other ways with the given words.
老师：Here, please have a try. We can find it has been on since an hour ago, and it has been on for an hour. So please remember when we come across a period of time, we should use the long action. So when we come across things an hour ago and for an hour, we should change begin into half or has been on here. And from the sentences we can get the reason they think the program is boring, because there is always the same program on the screen.
老师：Pay attention to the word screen. Can you feel the meaning of it? Look at the picture here. There is a scream in the picture. And look at this one. It's a very big screen. We can watch videos. We can watch a lot of information on the screen. Let's move on to question 2. What will they do with the program? Picture 3 and 4 can help us find answer to this questio
