题型分类：表格填写题

题干分析：选择满足图表分类的正确选项

选项解析：

A选项：大气中水蒸气含量高。属于早期金星的特征，对应文章第二段的内容，比如“But if water vapor and carbon dioxide were once so common in the atmospheres of both Earth and Venus, what became of Earth’s carbon dioxide?”。
C选项：和地球的早期大气很相似。属于早期金星的特征，对应文章第一二段内容，比如“The original atmospheres of both Venus and Earth were derived at least in part from gases spewed forth, or outgassed, by volcanoes. The gases that emanate from present-day volcanoes on Earth, such as Mount Saint Helens, are predominantly water vapor, carbon dioxide, and sulfur dioxide. These gases should therefore have been important parts of the original atmospheres of both Venus and Earth.”。
 
B选项：二氧化碳仅仅以气态形式存在。属于当前金星的特征，对应第六段内容，比如“With no oceans to dissolve it, outgassed carbon dioxide began to accumulate in the atmosphere, intensifying the greenhouse effect even more. Temperatures eventually became high enough to “bake out” any carbon dioxide that was trapped in carbonate rocks. This liberated carbon dioxide formed the thick atmosphere of present-day Venus. ”。
F选项：完全缺失地表的水。属于当前金星的特征，对应第六段内容。
G选项：基本稳定的温度。属于当前金星的特征，对应第六段内容，“Over time, the rising temperatures would have leveled off, solar ultraviolet radiation having broken down atmospheric water vapor molecules into hydrogen and oxygen. With all the water vapor gone, the greenhouse effect would no longer have accelerated.”。
 
错误选项：
D选项：非常浓密但相对低温的大气。错误，当前的金星大气二氧化碳浓度高，但是温度相比早期金星更高。
E选项：完全被水覆盖。错误，早期的金星有海洋，但是文章没有说完全被海洋覆盖。
