- And there was quite a variety of them, too. The team found representatives of phyla called Actinobacteria,
- 并且种类多样。该团队发现的门类有，放线菌、
- Bacteroidetes, Firmicutes and Proteobacteria, all of which are familiar to microbiologists.

- 而出现的防止环境恶化的防护屏。
- But future Mars rovers will drill beneath the planet's surface into strata that have had equivalent levels of protection from rock above them, if not from seawater.
- 但未来的火星探测器将深入地球表面，钻探到具有同等保护水平的地层，这些地层即使没有受到海水的保护，也会受到上面岩石的保护。
- And a factor of 35, though large, does not sound insurmountable.
- 35倍差距的因素虽影响较大，但听起来并非不可克服。
