planet hosted life.the lake, which dates back some 3.4 billion years, appears to have covered as much as 80 square miles and was up to 1，500 feet deep, said the team from the university of colorado.“this is the first clear evidence of shorelines on the surface of mars，” said boulders research associate, gaetano di achille, in a study published in the latest edition of geophysical research letters.“the identification of the shorelines and accompanying geological evidence allows us to calculate the size and volume of the lake, which appears to have formed about 3.4 billion years ago.”analysis of the images has shown the water carved out the canyon(溪谷) in which it was found, which then opened out into a valley depositing(使淤积) sediment(沉积物) which formed a delta(三角洲)“finding shorelines is a great discovery to us”， said assistant professor brian hynek, adding it showed the lake existed at a time when mars was thought to have been cold and dry.scientists believe the oldest surfaces on mars formed during the wet and warm era known as the noachan epoch, about 4.1 billion to 3.7 billion years ago.the newly discovered lake is believed to date from the hesperian era and postdates the end of the warm and wet period on mars by 300 million years, according to the study.scientists believe deltas next to the lake may well hold secrets about past life on mars as such places on earth have become the natural deposits of organic carbon and other markers of life.11the size of the lake found on mars is _a80 square miles b1，500 square milesc3.4 billion square miles d300

contagious(具有传染性的) that chimpanzees can “catch” it from cartoons, according to research.scientists from emory university in atlanta，us, have discovered that a cartoon of a yawning chimp will stimulate(刺激) real chimps to yawn. they describe in the royal society journal，proceedings b，how this could assist in the future study of empathy(同感，共鸣)the work could also help explain if and how computer games might cause children to imitate what they see on screen.previous studies have already shown contagious yawning in chimpanzeesstimulated by videorecorded footage of yawns.“we wanted to expand on that，” explained matthew campbell，a researcher from emory universitys yerkes national primate research center and lead author of the study.“were interested in using cartoons for presenting stimuli to animals, because we can control all the features of what we show them，” he continued.although dr campbell doesnt think the chimps were “fooled” by the cartoons into thinking they were looking at real chimps, he explained that there was evidence that chimpanzees “process animated(动画的) faces the same way they process photographs of faces”he said, “its not a real chimpanzee，but it kind of looks like a chimpanzee, and they are responding to that.”he and his team, including devyn carter who designed the cartoons, showed the animals the yawning sequences.“we also had the cartoons doing other movements with their mouths that the chimps often do，” he said.“the chimps showed a lot more yawning during the yawn video than when the control videos were playing.”he told bbc news that the only way he and his colleagues could explain the “very strong difference” they saw was that seeing the yawns was making the animals yawn.15according to the passage, the scientists have found that _ayawning is a contagious facial expression among chimpsbchimps will imitate a cartoon chimp who is yawningcchimps are able to understand cartoons very welldchimps like watching cartoons very much16according to the passage we can learn that _ayawning on both cartoon videos and pictures can make chimps yawnbdevyn carter led the study about contagious yawningcchildren will also be stimulated
