Meanwhile, scientists were finding even
hardier4 microbes, now known as hyperthermophiles, 与此同时,科学家们正发现更耐热的微生物。现在,它们被称之为超喜温微生物,
which demand temperatures of 80 degrees centigrade (176 degrees Fahrenheit) or more. 要求80摄氏度以上的温度。
The warmest organism found so far, according to Frances Ashcroft in Life at the Extremes, is Pyrolobus fumarii, 弗朗西丝·阿什克罗夫特在《极端条件下的生命》一书中写道,迄今为止发现的最喜温的微生物是延胡索酸热球蛋白菌,
which dwells in the walls of ocean
vents5 where the temperature can reach 113 degrees centigrade (235.4 degrees Fahrenheit). 它们生活在海洋喷气孔的岩壁里,那里的温度高达113摄氏度。
The upper limit for life is thought to be about 120 degrees centigrade (248 degrees Fahrenheit), though no one actually knows. 生命的上限被认为是120摄氏度左右,虽然实际上谁也不知道。

"Wherever we go on Earth——even into what's seemed like the most hostile possible environments for life, “在地球上,我们无论走到哪里——即使进入看来对生命最不利的环境里,
as long as there is liquid water and some source of chemical energy we find life." 只要那里有液态水以及某种化学能,我们就能发现生命。”
Life, it turns out, is
infinitely6 more clever and
adaptable7 than anyone had ever supposed. 原来,生命比任何人想像的要聪明得多,在适应能力方面要强得多。
This is a very good thing, for as we are about to see, we live in a world that doesn't altogether seem to want us here. 我们马上就会明白,这是一件很好的事,因为我们所生活的世界,似乎并不完全希望我们待在这里。
