Conversation One
Listen to the conversation, mark each statement as either true (T) or false (F) according to what you hear.
The professor talks about the house while he is showing Sarah around.
T
Sarah说这个太阳能氢气生态屋的外观很奇特， 随后教授便介绍到设计时既使用了马来西亚传统设计风格， 又参杂了现代科技。 故可知教授带着Sarah参观时介绍了房子。 故该判断正确。
This is the biggest eco-house in the world to run on solar energy.
F
Sarah说如果能介绍一下这个房子怎么工作的， 游客会很感兴趣， 教授便说“这是世界上首个用氢气运转的房子”， 而不是“世界上最大的用太阳能运转的生态屋”。 故该判断错误。
Rainwater which runs down a pipe into a tank will be converted into oxygen and hydrogen.
T
Sarah问， 如果下雨了怎么办？ 教授解释， 雨水将会被收集进花园的水槽， 然后用太阳能产的电把雨水分解成氧气和氢气。 故该判断正确。
The hydrogen is kept in a tank in the garden because it is dangerous to keep it indoors.
F
Sarah问教授， 将氢气保存在花园是否是因为太危险了， 教授否定该说法并表示它实际上十分安全。 故该判断错误。
The hydrogen they get from water can power everything in the eco-house.

【听力原文】
W: Hello, I‟m Sarah Forbes. I‟m visiting the Advanced Engineering Centre in
Malaysia. You must be Professor Robinson.
M: Hello! Welcome to the Solar-Hydrogen Eco-house!
W: So this is it ... I must say, it‟s a very interesting-looking house.
M: Yes, it‟s the house of the future, but when we designed it, we used a traditional Malaysian house design as well as modern technology.
W: If you could explain how it works, I‟m sure our listeners will be very interested.
M: Sure. This is the first house in the world to run on hydrogen.
W: Oh! What‟re those things up there on the roof?
M: They‟re solar panels. When the sunlight hits them, the sun‟s energy is converted into electricity.
W: Wonderful. And what happens if it rains?
M: We collect the rainwater. It runs down that pipe into a big water tank in the garden. Then we use the electricity we make from the sun to convert the water into hydrogen and oxygen.
W: Brilliant! You can make oxygen as well?
M: Yes, but it‟s the hydrogen that we want. We keep it in a tank outside the house.
W: Why? Is it dangerous?
M: No, actually it‟s quite safe. Come and see the hydrogen gas tank. If you come this way, OK, ah...here it is. And that‟s the gas pipe that takes the hydrogen into the house.
W: What do you use the hydrogen for?
M: To power everything in the house―the cooking stove, the hot water.
W: That‟s pretty good.
【解析】Sarah问教授这些氢气能用于什么， 教授表示氢气可以给整个屋子供能，包括燃气炉和烧热水。 故该判断正确。
