Thank you! It is great to see any (so many) of you interested in (this series on) survival in out of (outer) space. We all take a TV section (Please excuse the cameras, we're being videotaped for the local TV stations.). Today (Tonight), we are (I'm) going to talk about the most basis (basic) aspect of survival-- The space suit. is easy to image, is that (When most of you imagine an astronaut, that's probably the first thing that comes to mind), right? Well, our (without) space suit is not enough (, it would not be possible for us) to survive in out of space. For example, out of (outer) space is wecure (a vacuum), (there's) no gravity and (or) airs (pressure), without protection, our body is (would) explode. With that (What's more), we’re cooking in the air and sun (we'd cook in the sun or freeze in the shade). (With) temperature is over 30s degrade above to cool low in zero high (ranging from a toasty 300 degrees above to a cool 300 degrees below zero Fahrenheit.). The space suit of astronaut is markeble (that NASA has developed is truly a marvel), it follow here, is one by astronaut space suit (This photo enlargement here is a life-size image of an actual space suit worn by astronauts on the last space shuttle mission.). This part also (is the torso), is made 100 laze extremely (it's made of seven extremely durable layers). This protect temperature (This thick insulation protects against temperature extremes and radiation). Next, it’s what we called “oxgeny” (a "bladder" of oxygen), that’s at oxgeny. Simulate by oxgeny . available area allow to be flexible (that's an inflatable sac, filled with oxygen, to simulate atmospheric pressure. This bladder presses against the body with the same force as the Earth's atmosphere at sea level. The innermost layers provide liquid cooling and ventilation. Despite all the layers, the suit is flexible, allowing free movement so we can work.). Another various physic space suit that I want to show you (really sophisticated part of the space suit is the helmet. I brought one along to show you.), can I have a volunteer (come and demonstrate)?
今天一坐下来,先听了一遍昨晚的 OG Listening 。 就开始听写,结果我发现压根听写不下来,平复一下心情,第二遍开始慢慢一句一句来,感觉不一样,听完一遍再听写没有那么难,虽然还是太烂了,但是至少感觉明白了它的主旨再听写,思路都顺很多。最难过的还是每次一到最后总有一大段压根就感觉头脑一片空白!!!惨!
