题目内容
【题目】据英国《每日邮报》报道，天文学家发现一颗绕昏暗恒星运转的类地行星，距地球仅40光年。它是一个热气腾腾的“水世界”，体积是地球的6倍。据推测，这个“水世界”同样拥有大气层，且75%的表面区域被水覆盖，但由于温度太高，它无法支持地球型生命的存在。结合材料，回答下列小题。
【1】“水世界”类地行星所在的天体系统是
A．地月系 B．太阳系 C．银河系 D．河外星系
【2】天文学家推测“水世界”类地行星无法支持地球型生命存在的主要依据是
A．该行星上没有水 B．该行星距离恒星太近
C．该行星温度太低 D．该行星不存在大气层
【答案】
【1】C
【2】B
【解析】
试题分析：
【1】由材料可知“水世界”类地行星距地球40光年，银河系直径为10万光年，因此该天体系统位于银河系，C正确。
【2】由材料“由于温度太高，它无法支持地球型生命的存在”可知，无法支持地球型生命存在的依据是该行星距离恒星太近，B正确。
