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、The surface of the ocean is expanding.
B、Volcanic activity is increasing.
C、The surface of the earth contains tons of cosmic dust.
D、Thousands of comets are colliding with the earth’s atmosphere.
答案
D
解析
细节题。浏览选项可知,四个选项各叙述了一种情况,应该是考查细节。对话中提到最近通过卫星拍摄的照片显示thousands of small comets colliding with the earth’s outer atmosphere(数以千计的小彗星撞击地球大气层),故答案选D。
