It is clear that human history will end: the only mystery is when. It is also clear that if the timing is left to nature(or, if you prefer, to God)and humans hang on until the bloody end, the race’s final exit will be ignoble(不光彩的). If future generations escape the saurian(蜥蜴类)agony of extinction by a wandering chunk of rock or ice, the sun’s unavoidable growth to gianthood will still burn their last successors to ashes: only cinders and gases and dust will remain.
Far future generations might prolong the process by posting colonies beyond the earth’s orbit, but these would be sad outposts at the end of the solar system’s long day, clutching memories of a lost planet and of billions of sacrificed souls. The difficulties—fantastic difficulties—of interstellar(星际的)travel might be overcome, but the mightiest of starships could do no more than defer the end of the world. An ignoble existence hopping from planet to planet—clinging to each clod until it, in its turn, was vaporized or frozen—might still be bearable were it not for the knowledge of its final uselessness. In the end, there is only death by gravity, the quantum(量子)pit or the heatless grey soup.
The great violinist Jascha Heifetz was great not least because he quit the concert stage at his peak, before the show became stale or the audience drifted away. To exit gracefully is sublime(美妙的), as Heifetz understood. And only one species is capable of choosing a similarly graceful exit: all others march on like robots. To call time on the human race by choice, not necessity, would be the final victory of the human spirit over animal nature, an absolute emancipation from the command of DNA Precisely because no other known life-form could do or even conceive such a thing, humanity must.
Science has revealed only one place in the universe that is hospitable to intelligent life, and humans are the only intelligence that, as far as is known, has ever enjoyed the opportunity to occupy it. If people left the stage after a reasonable run, in the fullness of time intelligence could evolve again(dolphin-people?
Chimp-people? orchid(兰花)people?). And then, in due course, when this new species deciphered(译解)human books or reached the marker that might be left for them on the windless moon, they would know that man ended his dominion so that theirs might begin. Imagine, then, how they will regard us. It is, far and away, the greatest act of goodness ever contemplated, the ennoblement of a whole species: an act, almost, of angels.
What does the author think interstellar travel can do?
选项
A、It practically enables human to escape the end of the world.
B、It simply postpones the process of human extinction.
C、It helps human avoid the fate of being vaporized or frozen.
D、It is a way to help human escape from death by gravity.
答案
B
解析
第2段第2句中的do no more than defer...表明星际旅行唯一的意义在于它可以推迟世界末日的到来,该段首句的the process指的就是上段讨论到的人类灭亡的过程,B为答案。
