  In a surprising discovery about where higher life can survive, scientists have found a shrimp -like creature and a jellyfish swimming beneath an Antarctic ice sheet.

  About 180 meters below the ice where no light can get through, scientists had figured nothing much more than a few microbes(微生物)could exist.

  That’s why a NASA team was surprised when they lowered a video camera to get the first long look at the underbelly of an ice sheet in Antarctica.A curious shrimp-like creature came swimming by and then parked itself on the camera’s cable.Scientists also pulled up a tentacle(触须)they believe came from a jellyfish.

  “We were operating on the presumption that nothing’s there.” said NASA ice scientist Robert Bindschadler.“It was a shrimp you’d enjoy having on your plate.”

  “We were just gaga(狂热的)over it,” he said when talking about the 7.5 cm long, orange creature starring in their two-minute video.Technically, it’s not a shrimp.It’s a Lyssianasid amphipod, which is distantly related to the shrimp.

  The video is likely to inspire experts to rethink what they know about life in harsh environments.And it has scientists thinking that if shrimp-like creatures can live below 180 meters of Antarctic ice in freezing dark water, what about other cold places? What about Europa, a frozen moon of Jupiter?

  Cynan Ellis–Evans, a scientist of the British Antarctic Survey called the finding fascinating.He said it was possible the creatures swam in from far away and don’t live there permanently.

  But Kim, who is a co-author of the study, doubts it.“The site in West Antarctica is at least 19 km from open seas.Bindschadler drilled a 20 cm-wide hole and was looking at a tiny amount of water.That means it’s unlikely that two creatures swam from great distances and were captured randomly in that small area,” she said.

  “Yet scientists were puzzled at what the food source would be for these creatures.While some microbes can make their own food out of chemicals in the ocean, complex life like the shrimp can’t,” Kim said.zxxk

  “So how do they survive? That’s the key question.” Kim said.

  “It’s pretty amazing when you find a huge puzzle like that on a planet where we thought we know everything.” Kim said.

Houston, Texas (June 8. 2002)–in 2004, the National Aeronautics and Space Administration (NASA) will send two robots to separate places of Mars to seek out past or present signs of water. It is an exciting idea to send two robots driving over very different places of Mars at the same time, to be able to see what is on the other side of the hill.
Last month, NASA announced it was sending one robot to Mars, but after two weeks, it decided there was enough money for two. The robots will be sent up within two weeks of each other in May and June of 2003 from Kennedy Space Center. If all goes well, the two spacecraft will touch down on Mars, after a seven-and –a-half-month space flight, on January 2 and 20, 2004.
The robots, each weighing 150 kilograms, can cover 100 meters per day. They are designed to be able to examine the mineral content of the soil, and their special camera will take pictures of the lands and hills. Although they will be under control from the earth, the robots are able to move more freely compared to those sent up before them.
The actual landing points have not been determined yet, but the scientists say it will be in areas where they hope to find water.
49.According to the news report, scientists plan to send robots up to Mars to _____.
A.find out whether there is water on Mars   B.see if robots can find minerals there  
C.test how fast robots can drive there                 D.prove that robots can work on Mars
50.How long in between will the two robots be sent to Mars?
A.1 year       B. 7.5 months                  C. 2 months       D. 2 weeks
51. One of the important jobs for the robots on Mars is to _______.
A.study the soil                                     B. walk everywhere
C.test the new camera                                D. find a suitable landing point
52. We can infer from the last sentence that scientists ________.
A. have changed the landing points many times  B. hope to land the robots on the surface of water
C. are still working on the plan                      D. know where they can find water
