M: How did you like yesterday’s astronomy class?
W: It was interesting, but the point she was trying to make seemed a little far-fetched.
M: Oh, that new theory that ocean water came from comets?
W: Yeah. Do you remember what it’s based on?
M: Some recent satellite photos, I think. Apparently, space satellites recently detected thousands of small comets colliding with the earth’s outer atmosphere, (19) almost 40,000 per day.
W: OK, so they collide with the atmosphere. Then that’s what created the water?
M: It’s not that the collision created water. Comets contain water. They are made up mostly of cosmic dust and water. When they collide with the atmosphere, they break up and the water they contain rains down to the earth. Ocean water came from that raia (20)
W: Oh, well, this morning, I asked my geology professor about that. He said that most geologists don’t accept it. (21)
M: Why not?
W: Well, their research indicates that most of the water molecules from the comets will have burnt up as they fell through the atmosphere. Enough rain couldn’t have reached the earth to fill up the ocean.
M: Well, do the geologists have an alternative theory to explain where ocean water came from?
W: Yeah, he said the more traditional view is that ocean water came from volcanoes.
M: From volcanoes?
W: Right! As the volcanic fumes are mostly steam. And they claim that it was volcanic steam that created the oceans, not rain from comets.
19. What did recent photographs from a space satellite indicate?
20. According to the new theory, where did ocean water come from?
21. What group disagrees with the new theory described in the conversation?
选项
A、Disintegrating comets.
B、Gases in the atmosphere.
C、Underground water that rose to the surface.
D、Water vapor.
答案
A
解析
细节题。浏览选项可知,四个选项各涉及一种事物,应该是考查细节。由于在选项中无法找到对话里直接提到的答案,因此可用排除法解题。A项disintegrating comets(崩裂的彗星),B项gases in the atmosphere(大气中的气体),C项underground water that rose to the surface(上升到地表的地下水),D项water vapor(水蒸气)。根据对话中的新理论,海洋中的水产生的过程是彗星撞击地球后,其自身携带的水由于撞击作用会飞溅出来,然后转化成雨水落到地球表面,从而形成海洋的水。由此可见B、C、D都不对,故答案选A。
