14、多的火山了C)它被一层很厚的云层所覆盖D)金星上的温室效应无法得到掌握D从首段第3、4句可以推断，金星比其他行星都热，是由于温室效应肆虐，因此此题选D。A关于金星离太阳的距离，B关于金星上的火山，C关于掩盖金星的云层，都在这一段中提到，虽然根据常理，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，故可排解。2.一些行星学家认为，金星上不曾存在过生命，由于_。A)他们没有发觉金星上有水的遗迹B)他们认为金星温度太高，不行能存在任何生命C)金星被肮脏有毒的云层所覆盖D)金星是离太阳其次近的行星A文中多处从正面和反面说明，一些科学家信任Venus上没有生命是由于那里没有水。正面的依据如第5段
