1·He said that scientists are now studying below the seafloor near deepsea volcanic vents, and at Earth's icy poles, for microbes that might be analogs of extraterrestrial life.
他说，科学家们目前正在对深海火山口附近的海底以下及地球冰封的极点进行研究，以求找到可能与地外生命类似的微生物。
2·One theory is that they came from comets and asteroids, which pounded the lunar surface billions of years ago, and later drifted to the poles.
有一种说法是，它们来自于数亿年前撞击月球的慧星和小行星，后来转移到了极点。
3·Much of what is known about recent ice ages comes from drilling into the ice at the planet's poles.
人们对近期冰川季的已有认识，大部分都得益于对地球极点冰层的钻探。
4·Springtime on Mars is quite a bit balmier than the planet's winter season, but it's still plenty icy near the Red planet's poles.
火星上的春季相较该星球的冬季要温和的多，不过靠近这个红色星球的极点仍旧十分冰冷。
5·Even if we can manage to slow the growth in carbon emissions, the poles will likely continue to warm.
即使我们减低碳排放的增长速度，极点依然有可能持续变暖。
