Now listen carefully and answer questions thirty-one to forty. 00:00:19,420 Good afternoon. As you know, the world is running out of fossil fuels, that is crude oil, coal, and natural gas. As an alternative, certain plants are now being considered as biofuels, which are fuels made from organic plant material. Few things that make this plant especially attractive is that it can survive in very poor quality and fertile soil, as it does, for example, alongside train tracks in India on the line between Mumbai and Delhi. And for up to three years, it's resistant to drought. That's right. It can do without rain for that long. And even if it's not actually a plant that people can eat, it's still worth having it on your land as it prevents erosion. And we looked at the dangerous consequences of that in a previous lecture. Furthermore, Jatropha seeds can be slowly distilled to produce diesel oil, and it's this kind of fuel. Of course, that's of interest to scientists and power companies. After processing, the seeds can yield up to four times the oil that soybean can and ten times the amount compared to corn. No doubt that it is a remarkable plant and one that has been very beneficial to men in various African communities. It's been used to operate water pumps and refrigerate medicines. It can be used to produce candles or as a fencing plant to keep some animals enclosed and some animals out. For example, the boiled leaves can do much to relieve the suffering of people with malaria, and some Jatropha species have seeds which are used to treat digestion problems. When the plants are burnt, they release carbon dioxide, but they absorb great amounts when they're growing, making them a considerably greener alternative to fossil fuels. To provide land for palm oil or sugar cane plantations. For instance, companies are cutting down vast areas of rainforest which can never be replaced, and this in turn results in the disappearance of wildlife which depended on that habitat. You can also imagine that such deforestation makes a considerable contribution to global warming. ## 题目与答案 ### 31.
