Yet a small group of advanced life-forms on Earth begs to differ. and theorizes that bizarremicrobial ecosystems might have once populated Venus and. in fact. may be there still.Members of this loose band of researchers suggest that their colleagues have water too muchon the brain, and are, in a sense, H2O chauvinists(盲目的爱国者).
"Astrobiologists are neglecting Venus due more io narrow thinking than actual knowledge of theenvironment,or environments. where life can thrive." says Dirk Schulze-Makuch, ageobiologist at the University of Texas at El Paso who recently co-authored a Venus-boostingpaper in Astrobiology wich colleague Louis Irwin.
The bias against life on Venus is partly rooted in our own biology. Human experience instructsthat liquidwater, preferably lot of it. is essential for life. In search for extraterrestrial life, weobsess over small rivers in Mars' surface apparently carved by ancient gushes of water. anddelight in hints of permafrost (永久冻结带) just underneath its surface. (By comparison. Venusisn't even that interesting to look at:A boring cue ball (台球的白色母球) for backyardastronomers, its clouds reflects 75% of visible light.) Attention and then funding follow thewater: Three more landers will depart for Mars this spring. and serious plans for sample-returnmissions hover in the midterm future.
"If you have limited resources, you base exploration on what you know." says Arizona StateUniversity planetary geologist Ronal Greeley. It's like losing your keys on the way home alnight: The first place you look is under the streetlights not because they're more likely to bethere. but because if they are. you’llspot them. For astrobiologists. the streetlights are thespectral (光谱的) lines for water. and they've spotted that potential on Mars, Jupiter's moonEuropa. even Neptune's moon Triton. Not on the baking rocky flats of Venus.

英语六级冲刺阅读训练答案
1.金星是太阳系九大行星里面最热的，因为__________________。
A)它不像水星一样离太阳这么近
B)整个行星上有太多的火山了
C)它被一层很厚的云层所笼罩
D)金星上的温室效应无法得到控制
[D]从首段第3、4句可以推断，金星比其他行星都热，是因为温室效应肆虐，因此本题选D。A关于金星离太阳的距离，B关于金星上的火山，C关于覆盖金星的云层，都在这一段中提到，虽然按照常理，这些因素都可能使某个地方的温度上升，但它们均无原文依据，故可排除。
2.一些行星学家认为，金星上不曾存在过生命，因为_____________。
A)他们没有发现金星上有水的遗迹
B)他们认为金星温度太高，不可能存在任何生命
C)金星被肮脏有毒的云层所笼罩
D)金星是离太阳第二近的行星
[A]文中多处从正面和反面表明，一些科学家相信Venus上没有生命是因为那里没有水。正面的依据如第5段开头两句及末段;反面的依据如第3段中的那个研究地球高级生命形式的小团体对认为Venus上没有生命的看法的驳斥;由此可见，本题答案应为A。
3.从文章中可以推断，一个研究地球高级生命形式的小团体认为______________。
A)生命是可以在很热的环境里存在的
B)没有水也可以存在生命
C)金星上现在还有生命
D)火星上曾经存在过生命
[B]第3段末句表明，这一个小团体的研究人员认为那些宣称Venus上没有生命的科学家是H20 chauvinists 即他们太盲目认为水是生命存在的基本条件。)也就是说，这个团体相信生命的存在不一定需要水，因此B为本题答案。A无原文依据，C、D将文中并不肯定的猜测(文中有might，may)转变为肯定的事实，显然不符。
4.从文章中我们知道了关于金星和火星的什么信息?
A)金星的气压比火星高。
B)金星研究得到的关注和资金比火星要多。
C)金星比火星更靠近太阳。
D)金星比火星看上去更漂亮。
[C]从首段第3句可以知道水星是离太阳最近的行星，而金星只比它离太阳远一点，也就是说金星比其他七个行星离太阳都要近，当然也就比火星离太阳近了，因此C为本题答案。
5.由Dirk Schulze-Makuch和Louis Irwin共同撰写的论文是为了要________________。
A)介绍他们关于金星的研究发现
B)提倡探索金星
C)让别人相信金星上曾经存在过生命
D)批判其他的科学家，认为他们坐井观天
[B]第4段中的a Venus-boosting paper说明这篇文章的目的是推动(boost)金星研究或探索，而不是A所说的introduce(介绍)，因此B为本题答案。
