托福听力荟萃 60（在线收听）

Thank you. It's great to see so many of you interested in this series on "Survival in Outer Space." Please excuse the cameras;we're being______for the local TV stations. Tonight I'm going to talk about the most basicaspect of survival—the space suit. When most of you imagine an astronaut,that's probably the first thing that comes to mind, right? Well, without spacesuits, it would not be possible for us to survive in space. For example, outerspace is a______—there'sno gravity or air pressure; without protection, a body would explode. What'smore, we'd cook in the sun or freeze in the______with temperatures ranging from a______300 degrees above to a cool 300 degrees below zero______. The space suit that NASA has developed is truly a______. This photo______here is a______image of an actual space suit worn by astronauts on the last space______.This part is the______. It’s made of seven extremely______layers. This thick______protects against temperature______and radiation. Next is what they call a"______"of oxygen that's an______, filled with oxygen, to simulate atmospheric pressure. This bladder presses against the body with the same forceas the Earth's atmosphere at sea level. The______layers provide liquid coolingand______.Despite all the layers, the suit is flexible, allowing free movement so we canwork. Another really sophisticated part of the space suit is the______.I brought one along to show you. Can I have a volunteer come and______?

谢谢。看到你们这么多人都对“外太空生存”感兴趣真好。请不要介意摄像机，我们在给当地的电视台录像。今晚我要讲一讲在外太空生存的最基本的方面——太空衣。当你们大部分人想象到一个宇航员时，太空衣是最先在脑海中出现的，对不对？没有太空衣，我们就不可能在外太空生存。比如说，外太空就像一个真空——那里没有重力或者空气压力。没有保护，身体会爆炸。而且，在温度从暖烘烘的300华氏度到冰冷的零下300华氏度的变化下，我们会在太阳里被烤熟或者在背阴处冻结。NASA研制的太空服是一个真正的十分灵巧的东西。这个放大的照片是一个和实物一样大小的图像，反映的是在上一次航天飞机的任务中，宇航员穿着真正的太空衣。这个部分是身体躯干。它是由7个非常耐用的层制作的。粗的绝缘材料保护温度末端和辐射。下一个是他们叫做氧气“囊”的充气囊。它里面充满了氧气，模仿大气压力。这个囊对身体的压力和地球大气层对海平线的压力一样。最里面的层提供液体冷却和通风。尽管有这些层，太空衣很灵活，允许自由的运动，所以我们可以工作。另一个太空衣很复杂的部分是头盔。我带了一个来给你们看。有没有志愿者想上来展示一下吗？
