疑问和进行审视。
Lesson 6
1. There has arisen a thing called life—flamboyant, rambunctious, gregarious form of matter, qualitatively different from rocks, gas, and dust, yet made of the same stuff, the same humdrum elements lying around everywhere.
出现了一种叫做生命的东西——物质的一种形态:它与岩石、气体以及尘埃有本质的不同, 但却由同样的东西,到处存在的同样的元素构成。
2. Extraterrestrial life represents an enormous gap in our knowledge of nature.
外空是否存在生命,这是我们对自然认识的空白。
3. We don't know how truly alien it is. We don't know if it's built on a foundation of carbon atoms. We don't know if it requires a liquid-water medium, if it swims or flies or burrows.
我们不知道这种生命是否建立在碳原子基础上,是否需要液体形态的水作为中介,是游呢、飞呢,还是生活在地下。
4. But neither are people who believe in the UFO narratives irrational, much less crazy, as they are sometimes depicted.
对外星人乘坐飞碟光临地球这种说法深信不疑的人,并不像人们有时候所说的那样,是逻辑混乱,更不是丧失理智。
