A、Explosion in technology. B、Explosion in population. C、Explosion in farming. D、Explosion in computer. A信息题。当提到上一次上Owen博士的工业革命课程

T: Do you remember that lecture we had last time on the Industrial Revolution?
H: You mean when Dr. Owen was talking about the explosion in technology?
T: Yes. And didn’t he mention something about fertilizers being invented?
H: That’s right, he did. If I remember correctly he said that chemical fertilizers were used so that more food could be grown without having to use more land, and this enabled the Industrial Revolution to take place. In fact I’ve got the reading list he gave us. If you like I can go to the library and try to find out more information.
T: Yes, and that can form the first part of the essay.
H: So what do you suggest for the second part?
T: In the second part we can talk about the technology that is used in modern farming methods.
H: That’s too big a leap. That will have to form the final part. Of course I will write that. For the second part we need to talk about the inventions that were made during the 18th and 19th centuries.
T: What, like tractors, you mean?
H: No, mechanical vehicles weren’t invented until the early 20th century. But it’s important to mention that because it meant that, when machines were invented, farm land that was used to grow hay, to feed the horses, could be used to grow food for people.
T: OK then. So I’ll try to find out as much as I can about technology in the 19th century. If you like I’ll also look at the developments in the 20th century.
H: Such as?
T: Gene technology, of course. In fact by manipulating plants’ genes, scientists have been able to invent crops that can grow not only more food but that can grow in places where they wouldn’t naturally grow.
H: What, in places where it’s too hot or too dry you mean?
T: Well, I guess so. But I was thinking more of plants that are resistant to disease.
H: Yeah, that’s a great idea.
T: So you can do some research into 20th century technology then? H: Actually I was going to suggest we do that together given that it is such a big topic area.
T: Yeah, I guess you’re right. We can make that a joint effort, then. This is really great, we’re getting somewhere with this essay now.
H: I think we have enough to keep us going for now, so why don’t we go to the library and do what research we can, and we could meet again, say next Tuesday?
T: Tuesday’s out for me, I’m afraid, because I have a tutorial. Let’s make it the day
