火星

在火星上你看到的第一件东西是两个极地冰帽中的一个。

A research team led by Peter Doran of the University of Illinois at Chicago drilled through more than 39 feet of ice to collect samples of bacteria and algae.

在以后的探险中，还会谨慎地对更深的冰层和水提取样本，对将来或许会用于火星的技术进行检测。

这张图片显示的是火星上一个陨坑内的沙丘地，该陨坑是小行星撞击形成的。

The black spot at the top is a dust devil climbing a crater wall on Mars .

该黑点上方是一个沙尘暴攀登一个弹坑壁在火星上。

As the dust devil moves across the surface of Mars it can pick up and disturb loose dust, leaving behind a track.

尘卷在火星表面移动的过程中，会把松软的尘埃卷起来，在身后留下黑色轨迹。

Fresh dust devil tracks have been seen on Mars before, but actually seeing one up close was a surprise.

以前也曾发现过火星尘暴刚刚活动过的痕迹，但能看到上图这样接近的情景的确很令人惊奇。

A small impact crater, pitted knobs, and a criss-cross mesh of dust devil trails across the martian surface.

一个小撞击坑，进站旋钮，和纵横交错的沙尘暴在火星表面的小径交叉网。

A dust storm in the beginning of the Martian winter has brought about that end.

火星初冬的一场沙尘暴导致了这个结果。

But lacking the Earth's plate tectonics, Mars is unable to recycle any of this carbon dioxide back into its atmosphere and so cannot sustain a significant greenhouse effect.

但缺少地球的板块构造，火星是无法回收的任何这种二氧化碳进入大气，因此不能维持一个重大的温室效应。

The Earthling and the Martian agree that she holds a single object in her hand, but they disagree over what its sort is.

地球和火星的都认为她拿着一个客体，但她们对什么类型的客体的想法并不一样。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
