Ⅱ.阅读理解increasing hopes of discovering evidence that billions of years ago the red 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.，” said Boulder's research associate, Gaetano Di Achille, in a study published in the latest edition of Geophysical Research Letters.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 sediment(沉积物) which formed a delta(三角洲)． 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.s 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.

Yawning is so 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，，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.，” explained Matthew Campbell，a researcher from Emory University's Yerkes National Primate Research Center and lead author of the study.“We're interested in using cartoons for presenting stimuli to animals, because we can control all the features of what we show them，” he continued.he explained that there was evidence that chimpanzees “process animated(动画的) faces the same way they process photographs of faces”．“It's not a real chimpanzee，but it kind of looks like a chimpanzee, and they're responding to that.”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.”d explain the “very strong difference” they saw was that seeing the yawns was making the animals yawn.

课时作业(十九) 考查非谓语动词。此处是非谓语动词作状语。非谓语的否定式是在非谓语动词前加not且其动作在谓语动词动作之前已经发生，故用现在分词的完成式，选A。 表示“某人也不……时”，应该用倒装句型“neither/nor＋助动词/系动词/情态动词＋主语”。 考查动词词义辨析。publish印刷；出版；distribute分发；分配；represent代表；象征；treasure珍视；重视。由句意“……让几个学生帮着给班内的学生发新书”可知应选B项。 考查形容词辨析。strange奇怪的；amusing可笑的；curious好奇的；satisfied满意的。be curious about对……好奇。句意：孩子们被警告不要对他们不应该知道的事太好奇。 考查非谓语provide 与其所修饰的envelope是动宾关系，所以用过去分词作后置定语，表示“被动和完成”。 分析句子结构可知，and前后连接的是两个接连发生的动作(“said” and “walked”)，因此考查的是非谓语动词，故正确答案是A，现在分词作伴随状语，表分词动作(turning)伴随主句动作(walked)发生。B项把原句and放在第二个逗号后，前后连接三个接连发生的动作，才可以选；C项从时态上D项不定式表将来或目的，不合语境。 考查动词辨析。function起……作用，发挥功能，运转。句意：厨房通常是家里最忙碌的房间，因此确保它很好地发挥功能很重要。smooth 使……顺利，抚平； pay 付款； measure 测量。 考查介词短语辨析。at ease轻松，自由自在。句意：简做演讲时总是很紧张；当与他人在一起时，她必须使自己轻松自在。in disguise 假装； at risk 冒险； in relief 欣慰地。 考查介词短语辨析。regardless of不管。句意：这些国家的人们要求平等待遇，不管种族、宗教或性别。 考查动词短语辨析。turn out结果是。turn up出现；turn down 关小，拒绝；turn around 转身。 考查动词短语辨析。put up张贴，符合句意。句意：运动会的结果将在星期日上午张榜公布。 put away 收起来； put off 拖延； put down 放下，镇压。 考查介词短语辨析。in case 以防，万一。by nature 天生地；in return 作为回报；by chance 碰巧。句意：我认为我们以前已谈论过这个话题，但是我将再问一下以防万一。 根据问句中的broken down可知，这两国间有可能发生武装冲突。be likely to do sth 很可能会做某事。注意：四个选项中，只有likely是形容词，在这里用作表语。 考查冠词的用法。at ease(舒适、快活、自由自在)和lose face(丢脸)都是固定搭配，名词前均不加冠词。 考查交际用语。句意：“她会介意与她之前的队友们对垒吗？”“不会！她喜欢与任何强劲的选手比赛。”I think so.我想是这样的。I'm not surprised.一点也不奇怪。Of course.当然。Not likely！(大概)不会！此处表示不介意，所以D。本文记述了美国科学家对火星的探索情况。 细节理解题。根据第二段可知答案为A项。 细节理解题。根据第六段中…it showed the lake existed at a time when Mars was thought to have been cold and dry.可知答案为C。 细节理解题。由原文最后一句可直接得出答案。 推理判断题。由第一段内容可知火星上湖岸线的发现只是增加了人们发现亿万年前火星上曾经存在生命证据的可能性，但并不能推出火星上现在有生命。研究表明，黑猩猩会模仿动画片中黑猩猩的打呵欠动作，如果能充分利用黑猩猩的这种模仿能力，人类对动物行为的控制将取得重大突破。 细节理解题。根据第二段第一句可知黑猩猩看到动画片中打呵欠的黑猩猩 细节理解题。根据第五段后半部分中的内容可知无论是动画片中还是图片中的打呵欠动作都可以让黑猩猩打呵欠。 推理判断题。黑猩猩看到动画片中打呵欠的黑猩猩后会进行模仿，第四段的后半部分提到科学家可以控制所有的播放内容，由此可推断科学家希望通过研究黑猩猩的模仿行为来控制动物的行为和举止。 主旨大意题。本文是一篇研究报道，第一段是文章的中心段，根据该段内容可
