Listening text Ⅰ
Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now Better
Bill: Much better, thanks. But how was it
Judy: Wonderful! I especially liked an area of the museum called Light Games. It was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!
Bill: A hall of mirrors can be a lot of fun. What else did they have
Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it.You'll never guess what those bright lights were!
Bill: Come on, tell me!
Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows in every colour of the rainbow!
Bill: Oh, I wish I had been there. Tell me more!
Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder.You could use it to speak in a whisper to someone 17 metres away.
Bill: It all sounds so cool. I wish I could have gone with you.
Judy: I know, but we can go together this weekend. I'd love to go there again!
Bill: That sounds like a great idea!
1. The conversation is about the City of Science and Industry, a museum in Paris. Would you like to go to this museum Why or why not
Post-listening
Yes.
I would like to go to this museum to see the blue screen. I am curious to know what on earth is going on there and why I can see my blood cells moving around like tiny bright lights. I am sure it will be a lot of fun.
No.
It is not convenient because it is too far from China and there is no need to go so far when we have so many interesting places at home. We can’t speak French and will have trouble in understanding what to do there.
2. Are there any museums like this in China What other interesting museums are there
Yes, there are, for example, the China Science and Technology Museum in Beijing and the Shanghai Science and Technology Museum.
