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 simulate² atmospheric³ 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.

【参考译文】

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？
