问题 Which is INCORRECT about Venus? [br]  
A starting point for all astronomy students should be the great star "Venus". Of course we know it is not a star at all but the second planet from the Sun and the sixth largest. Venus is usually visible with the naked eye. Sometimes referred to as the "morning star" or the "evening star" , it is by far the brightest "star" in the sky.(18)It is the brightest object in the sky except for the Sun and the Moon. Anyway, what I want to talk about is what Venus looks like from ground level. Venus is sometimes regarded as Earth’s sister planet. Both have few craters indicating very young surfaces. Their densities and chemical compositions are similar.(19)There are several layers of clouds, many kilometers thick, composed of sulfuric acid. These clouds make it totally impossible to see what the surface is like. How about winds? It might surprise you that they are not that much different than earth’s, in fact, perhaps even slower. There are strong winds at the cloud tops—up to 350 kilometer per hour, but winds at the surface are very slow, no more than a few kilometers per hour.(20)Venus probably once had large amounts of water like the Earth but it all boiled away so now it’s quite dry. Earth would have suffered the same fate had it been just a little closer to the Sun.

选项 A、Because of the volcanic activity.
B、Because it is so dry.
C、Because it is near the Sun.
D、Because of the strong winds.

答案 C

解析 语义理解题。根据句(20)可知,金星也有可能像地球一样曾经有大量的水存在,但是都蒸发掉了,现在的金星非常干燥。如果地球也像金星一样离太阳那么近,也可能会遭受同样的命运。因此C为正确答案。
