六级练习2016.01.27


       
       




M: How did you like yesterday’s astronomy class?
W: It was interesting.(1)_____________________________________________.
M: Oh, that new theory that ocean water came from comets?
W: Yeah. Do you remember what it was based on?
M: Some recent satellite photos, I think.Apparently, Space satellites recently detected thousands of small comets colliding with earth’s outer atmosphere, almost 40 000 per day.
W: Ok, so they collided with the atmosphere.So that’s what created the water?
M: It’s not that the collision created water.Comets contain water.(2)_______________________________________.When they collide with the atmosphere, they break up.And the water they contain rains down to earth.Ocean water came from that rain.
W: Oh. Well, this morning I asked my geology professor about that.He said that most geologists don’t accept it.
M: Why not?
W: (3)_________________________________________________.Enough rain couldn’t have reached the earth to fill up the ocean.
M: Well, did the geologists have an alternative theory to explain where ocean water came from?
W: Yeah, he said the more traditional view is that the ocean water came from volcanoes.
M: From volcanoes?
W: Right. They say volcanic fumes are mostly steam.And they claimed that it was the volcanic steam that created the oceans, not rain from comets.
