さて、昨日は英語での発表（兼テスト）がありました。 以下、私が発表した内容。 We will make a presentation about “development of the Alternative Energy”. In late years, petroleum price jumps up. Influence of petroleum remarkable rise is not only its products. Due to the fuel of the tanker and airplane also rises. The price of the import and export products rises, too. There are three reasons. First, the situation of the petroleum-producing countries of the Middle East turns worse. It is too expensive to mine petroleum at unsafe position. Second, the users such as developing countries that need more petroleum increased. And moreover it is a cause that consumption keeps increasing at developed countries. Third, big companies attend to there, and began speculative investment. This is the greatest cause that the investment funds which need no petroleum speculate with profit motive. Well, what should we do to live through the time of sudden rise? Generally thinking, stop these three matters and return to the usual price. But, this is the story like a dream. So, we thought some ideas that development of the alternative energy which we never need petroleum. 途中繋ぎが入って･･･ If development advances, we don’t need more petroleum. That’s all for our presentation. Thank you very much.
