Now it's line that the human body has developed its millions of nerves to be highly aware of what goes on both inside and outside of it. This helps us adjust to the world. Without our nerves—and our brain, which is a bundle of nerves—we wouldn't know what's happening. But we pay for our sensitivity. We can feel pain when the slightest thing is wrong with any part of your body. The history of torture is based on the human body being open to pain. But there is a way to handle pain. Look at the Indian fakir who sits on a bed of nails. Fakirs can put a needle right through an arm. And feel no pain. This ability that some humans have developed to handle pain should give us ideas about how the mind can deal with pain. The big thing in withstanding pain is our attitude toward it. If the dentist says, "This will hurt a little", it helps us to accept the pain. By staying relaxed, and by treating the pain as an interesting sensation, we can handle the pain without falling apart. After all, although pain is an unpleasant sensation, it is still a sensation, and sensations are the stuff of life. The purpose of this passage is mainly to tell us ______. A．that pain is good for us B．to stop taking the "needle" at the dentist's C．how to handle pain D．how to avoid torture

B: It’s quite difficult to make a kind of hierarchy of worry here, because so many issues are there, and so … and they’re all very very important. But I think it has to be said that as far as we we’re concerned, as a campaigning organization, it really is the rain forest that we are concentrating on most. If we don’t take action on that issue within the next five years, then environmental pressure groups won’t have anything to do in ten years’ time, because there won’t be any rain forests, really, for them to campaign about. So this is a critical period for the rain forests, the next five years, and there is enough flexibility in the system to allow us to hope that we’re going to be able to make some changes during that time. So that’s why we’ve made it our priority. A: What’s so important about the rain forests, then？ Er, what’s, what’s the difference between having them or not having them？ Isn’t it just, you know, basically either there’re a lot of trees there or there aren’t a lot of trees there？ B: Uhh…well that’s what some people would like to think. Um, there, it’s important in many different ways, important firstly for the countries themselves, in terms of the fact that millions of people depend on the rain forests for their livelihood, and for their … the quality of their environment, through the protection of watersheds, and so on. Secondly, they’re important because of the biological richness of the rain forests. Um, a genetic chest … treasure chest is how they’ve been described. Um, more than 60% of the world’s species is to be found in the rain forests. Write that off, and you write off that genetic storehouse. Lastly, they’re important at international level because of the impact on climate patterns that one would find if the rain forests were destroyed. So, whether you’re looking closely at the tribal people who depend on them, the countries which depend on them, the international community which depends on them, indeed the, the, you know, the creatures themselves, um, it’s actually the most critical issue that we face. And our prime job is of course to try and get people to understand how it is, even in countries where there are no rain forests, that they still have a connection with that rain forest.
