Each as large as a football field, they may be openings into natural caves below the Martian surface.“If there is life on Mars, there is a good chance youd find it in caves,” said Jut Wynne, one of the researchers who noticed the features while working on a US Geological Survey Mars Cave Detection Program.Jonathan Clarke, a geologist with the Mars Society of Australia, yesterday described the discovery as exciting.One photo taken at night by an infrared imager(红外线成像器) showed one hole to be unusually warm, suggesting hot air trapped during the day is flowing out.“I said: Wow, thats a cave” Dr. Clarke said excitedly. “People have been looking for these for a long time; now we have found them.”He agreed such caves would be perfect places to hunt for life escaping from the bitterly cold, radiation-soaked (充满辐射的), dry surface.“Tiny drops of water could collect inside,” he said. “If there are gases coming out, they could provide energy for a whole range of bacteria. A cave is also a protection from radiation; the surface of Mars is exposed to high levels of space radiation.”The caves probably formed when tube-shaped lave flows (管状岩浆流) spread across the planet long ago. The outside of the tubes cooled, forming solid walls, while something hotter inside allowed the remaining have to flow out, forming caves. （07福建卷）1. What does the passage mainly talk about?A.
