A、Computers. B、Mobile phones. C、Farming technology. D、A, B and C D细节题。选项A、B和C在对话中都出现过，但题目要求找出Hannah对“technology”一词的理解。对话中有这样一段话：

T: Hi, Hannah. I was wondering when I’d bump into you. You know we only have another two weeks to complete that essay on modern technology for Dr. Owen.
H: I know, Terry. But don’t worry because I’ve been doing some research and I’ve got some great ideas.
T: Such as?
H: Well, it’s my guess that most people will write about computers, because that’s what everyone thinks about when they hear the word technology.
T: But that’s what technology is, isn’t it?
H: Yes, of course it is. But it’s many other things besides.
T: What, like mobile phones, that sort of thing?
H: Yes, but what about farming technology? It’s as much a part of people’s lives as computers or mobile phones.
T: What do you mean?
H: Just imagine, for a moment, if farmers couldn’t grow enough food to feed everyone. Then economics would mean nothing because no one would be able to work. Or even willing to go to work for that matter.
T: Yes, I see your point. Like those countries in Africa where people are starving.
H: Yes, indeed. Therefore, I suggest we write our essay on the development and impact of farming technology.
T: The development and impact of farming technology. Hmmm. That sounds impressive. Yet fanning only began about 5, 000 years ago, didn’t it?
H: Actually, it’s believed that plants were first domesticated about 10, 000 years ago, although a primitive type of plough and other basic tools were not invented for another 2, 000 years. But their invention made it possible to grow much more food and feed a much bigger population.
T: I see. And that would mean more people could spend time doing other things, such as building houses and developing other kinds of tools.
H: Exactly.
1. What is the possible relationship between the two speakers?
2. What are the two speakers mainly talking about?
3. What does "technology" refer to in Hannah’s view?
4. Why did the two speakers finally choose "fanning technology" as their research topic?
5. According to Hannah, when did farming technology first take place?
