听力原文：W: James, what's your opinion about nuclear energy? M: Nuclear energy? That's quite an issue! I actually have some pretty strong viewpoints regarding nuclear energy. Are you interested in hearing them? W: Yes. M: Well, in my opinion, nuclear energy is our best hope for the future. W: But don't you think it poses a threat to the safety of the population? M: Not really. As I see it, nuclear reactors are a clean and safe source of electricity. W: Well, if you ask me, people don't realize how dangerous radiation can be. M: The thing to keep in mind is that our oil and gas resources are limited. W: Let me say one more thing. M: Okay. W: I'd just like to point out that I think too many accidents are happening at nuclear power plants all over the country. M: You know honey, we could probably go on talking about this forever and never come to an agreement. W: You are probably right dear. I guess we just don't see eye to eye when it comes to nuclear energy. M: I guess not. (20)
