二、听力原文

PASSAGE 2 

A pair of entrepreneurs are planning to build and launch a spacecraft that would carry and roast coffee beans in outer space. The craft will use the heat of re-entry to roast coffee beans, as they float inside it in a pressurized tank. The effect would be to roast the beans all over and produce perfect coffee. The businessmen say that on earth, beans can easily break apart and get burned in the roaster. But if gravity is removed, the beans float around and in a heated oven, receive 360 degrees of evenly distributed heat and roast to near perfection. The spacecraft will reach a height of around 200 kilometers. The beans would then be roasted and the heat generated by the crafts 20 minute re-entry into earth's atmosphere. Temperatures and the pressurized tank will be kept to around 200 degrees Celsius. Once back on earth, the planet's first space roasted beans would be used to make coffee that would be sold for the first time in Dubai. This is where the pair's company is based. It is not clear how much they would charge for a cup. Surprisingly, the Space Roaster concept-should it go ahead-will not be the first attempt to take coffee into space. In 2015, two Italian companies collaborated on the construction of a similar type of spacecraft, which was the first coffee machine designed for use in space.

Questions 19 to 21 are based on the passage you have just heard.

Q19. What are a pair of entrepreneurs planning to do?

Q20. What does the passage say about coffee beans roasted on earth?

Q21. What did the two Italian companies do in 2015?

两位企业家正计划建造并发射一艘宇宙飞船，将咖啡豆送入太空并在太空烘烤。这艘飞船将利用重返大气层的热量来烘烤漂浮在加压水箱中的咖啡豆。这样做会均匀烘烤咖啡豆，从而生产出完美的咖啡。这两名商人表示，在地球上，咖啡很容易破碎，在烤箱里被烧焦。但如果去掉重力，咖啡豆就会漂浮在加热的烤箱里，接受360度均匀分布的热量，烤得近乎完美。宇宙飞船将达到200公里左右的高度。之后这些咖啡豆将被烘烤，飞船产生的热量将在20分钟后返回地球大气层。温度和加压水箱将保持在200摄氏度左右。一旦返回地球，地球上首颗太空烤制的咖啡豆将被用来制作咖啡，这将在迪拜首次出售。那里是二人公司的所在地。目前尚不清楚他们准备一杯咖啡售价多少。令人惊讶的是，太空烘焙机这一概念——如果能继续进行——那将不会是第一次尝试将咖啡带到太空。2015年，两家意大利公司合作建造了类似类型的太空飞船，这是第一台为应用于太空而设计的咖啡机。

请根据刚才所听文章回答19至21题。
