[Q]: M: Welcome back to your student union radio station. I'm with Catherine, who just successfully climbed the Great Mountain, Mont Blanc. Actually, she once did. The same climb in 2007. Catherine, was it easier the second time around? ,F: In many ways. They were totally different experiences. The first time I went as part of an organized group. We took 4 days to reach the top. This year, I decided to go alone with just one overnight stop, actually you're never really alone. It's all been crowded up there. The first climb, was quite difficult is the weather was very changeable, and we found ourselves climbing in very cold windy conditions. The weather this time was wonderful. Plus. I spent a few days before in chamonix and got myself more used to the height. If it's certainly made it easier, you can also achieve the same thing by climbing some of the smaller mountains first.
(A) M: You are used to climbing mountains in a group, and you never climb alone. (B) M: I’m sorry, I didn’t understand. Could you repeat a little louder, please? (C) M: You are so brave that you successfully climbed the Mont Blanc on your own. (D) M: You climb mountains with a guide? No wonder you just took 2 days to reach the top.

Mr. Watson, do you think we can really solve them all? ,M: I hope that world leaders can get together and agree on a plan for action. ,F: We need to solve the problem of air pollution. There's lots of clean modern technology that's out there. ,M: But many companies say it's too expensive. And developing countries pay more attention to industrial development than to environment protection. ,F: Everyone is looking at the problem in the short-term rather than the long-term. ,M: It's the same with the damage of the rainforests. Most companies just want the wood. ,F: They're not thinking about the long-term damage to the forests. ,M: No. In other parts of the world, especially in Africa, climate change and over-farming are causing farmland to turn into desert.
