【正文】 ’ll pass mountains and thousands of lakes and forests, as well as wide rivers and large cities. Some people have the idea that you can cross Canda in less than fice days, but they forget the fact that Canada is 5500 kilometers from coast to coast. Here in Vancouver, you’re in Canada’s warmest part. People say it is Canada’s most beautiful city, surrounded by mountains and the Pacific Ocean. Skiing in the Rocky Mountains and sailing in the harbour make Vancouver one of Canada’s most popular cities to live in. Its population is increasing rapidly. The coast north of Vancouver has some of the oldest and most beautiful forests in the world. It is so wet there that the trees are extremely tall, some measuring over 90 metres.”They saw the covered stadium, home of several famous basketball teams. As they walked north from the harbour area, Li Daiyu said, “Lin Fang, one of my mother’s old schoolmates, lives here. I should phone her from a telephone booth.”“Hello, my name is Henri. I’m a student at the university nearby,” he said,” and I was wondering where you are from.” The girls told him they were on a trp across Canada and that they had only on day in Montreal. “That39。Iqaluit – the frozen townBeth answered, “ I’m writing a story for my newspaper about Iqaluit – we’d like to advertise it as a holiday place, but I think it’s too cold.”Simon replied, “It’s dark in the day because we are so far north. You should e in June. The sun shines all night in the north then. That39。A STUDENT OF AFRICAN WILDLIFELeaving the moon’s gravity was not as painful as leaving the earth’s. But returning to the earth was very frightening. We watched, amazed as fire broke out on the outside of the spaceship as the earth’s gravity increased. Again we were pushed back hard into our seats as we came back to land. “ That was very exhausting but very exciting too,” I said. “Now I know much more about gravity! Do you think we could bisit some stars next time?” “Of course,” he smiled, “ which star would you like to go to?”But then the spaceship jumped again. This time it moved sideways and away from this edge of the “black hole”. Someone watching me would have seen the spaceship flying like a bird away from the “black hole”. But we felt nothing. At last we were able to look around us. Luckily the puter had started working again. We realized that we had discovered something new about “black hole”. If you go inside the edge of a “black hole”, it will “eat” you and there is no escape。A trip on “ The True North”After two days’ travel, the girls began to realize that Canada is quite empty. At school, they had learned that most Canadians live within a few hundred kilometres of the USA border, and Canada’s population is only slightly over thirty million, but now they were amazed to see such an empty country. They went through a wheatgrowing province and saw farms that covered thousands of acres. Afrer dinner, they were back in an urban area, the busy port city of Thunder Bay at the top of the Great Lakes. Because of the Great Lakes, they learned, Canada has more fresh water than any other country in the world. In fact, it has onethird of the world’s total fresh water, and much of it is in the Great Lakes.The next morning the bushes and maple trees outside their window were red, gold and orange, and there was frost on the ground, confirming that fall had arrived in Canada.The train left late that night and arrived in Montreal at dawn the next morning. At the station, people everywhere were speaking French. There were sighs and ads in French, but some of them had English words in smaller letters. “We don39。That night as the transfer was speeding along the St Lawrence River toward the Gulf of St Lawrence and down to the distant east coast, the cousins dreamed of French restaurants and red maple leaves.Beth said, “ I knew it would be could in January, but not this cold! Maybe there is a dog sled that can take me into town.”“I’m business man. My grandfather would live in ice houses when he hunted in winter, but not so many people do that now. the old men used to make one in a few hours. They used to live in skin tents in summer – the tents were easy to move so the people could follow the animals.”必修四 項目工藝技術方案豬場日排污水量60噸。 投資估算和資金籌措。 項目綜合評價結論結論：項目建設符合農(nóng)業(yè)結構調整需要和國家產(chǎn)業(yè)發(fā)展要求，與我國農(nóng)業(yè)生產(chǎn)環(huán)境保護和開發(fā)農(nóng)村可再生能源的戰(zhàn)略需求一致，符合農(nóng)業(yè)可持續(xù)發(fā)展的要求；項目建設目標明確，投資規(guī)模適宜，結構合理；項目管理系統(tǒng)健全；社會、環(huán)境和經(jīng)濟效益顯著，項目可行。 主要技術經(jīng)濟指標該項目主要技術經(jīng)濟指標見表11：表11 項目主要技術經(jīng)濟指標序號名 稱單 位指標值1產(chǎn)品品種與年均產(chǎn)量沼氣萬m3有機肥t2000沼液萬t2建設內容沼氣工程及綜合利用配套設施3投資基本建設投資萬元建設期利息萬元0流動資金萬元總投資萬元4資金籌措中央財政撥款萬元100地方配套資金萬元40自籌資金萬元5財務效益年均銷售收入（達產(chǎn)年）萬元年均總成本（達產(chǎn)年）萬元年均利潤（達產(chǎn)年）萬元內部收益率（所得稅前）%財務凈現(xiàn)值（所得稅前）萬元動態(tài)投資回收期（所得稅前）年第2章 項目建設背景 第2章 項目建設背景 項目的由來人民大垸農(nóng)場是畜禽養(yǎng)殖大場，監(jiān)利縣是湖北省畜牧業(yè)生產(chǎn)大縣，畜牧產(chǎn)業(yè)結構以豬禽為主。因而必須采取積極有效的措施，加強污染防治。生豬養(yǎng)殖是內陸地區(qū)發(fā)展畜牧業(yè)的主要方式，改良生豬品種已被農(nóng)業(yè)部納入畜牧業(yè)結構調整的重要內容。另一方面，養(yǎng)殖場的廢棄物如果得到合理處置和資源化利用，又能成為促進生產(chǎn)發(fā)展的有效資源。 項目建設是解決畜禽養(yǎng)殖業(yè)環(huán)境污染、促進企業(yè)可持續(xù)發(fā)展的需要大力發(fā)展生豬養(yǎng)殖業(yè)是湖北省農(nóng)業(yè)產(chǎn)業(yè)結構調整的重點。 項目建設是優(yōu)質農(nóng)產(chǎn)品生產(chǎn)的需要通過大型沼氣工程建設，豬場實現(xiàn)了清潔生產(chǎn)，提高了二元雜交種豬和三元雜交種豬的生活環(huán)境和場區(qū)環(huán)境，減少了種豬的疾病發(fā)生率，提高了種豬品質。（3）項目建設點內水、電已接入擬建場區(qū)，場區(qū)道路平整，達到“三通一平”的要求，滿足項目建設對基礎設施的需求。 （2）有機肥、沼液可以全部就近消納。第4章 項目承擔單位基本情況 第3章 產(chǎn)品市場預測與分析能源是現(xiàn)代社會賴以生存和發(fā)展的基礎，清潔燃料的供給能力密切關系著國民經(jīng)濟的可持續(xù)性發(fā)展，是國家戰(zhàn)略安全保障的基礎之一。另一方面中國人均能源資源嚴重不足，人均石油儲量不到世界平均水平的1/10，人均煤炭儲量僅為世界平均值的1/2。生物質遍布世界各地，其蘊藏量極大，僅地球上的植物，每年生產(chǎn)量就像當于現(xiàn)階段人類消耗礦物能的20倍，或相當于世界現(xiàn)有人口食物能量的160倍。 (一)發(fā)展現(xiàn)狀 近年來，受石油價格上漲和全球氣候變化的影響，可再生能源開發(fā)利用日益受到國際社會的重視，許多國家提出了明確的發(fā)展目標，制定了支持可再生能源發(fā)展的法規(guī)和政策，使可再生能源技術水平不斷提高，產(chǎn)業(yè)規(guī)模逐漸擴大，成為促進能源多樣化和實現(xiàn)可持續(xù)發(fā)展的重要能源。到2005年底，全世界生物質發(fā)電總裝機容量約為5000萬千瓦，主要集中在北歐和美國；生物燃料乙醇年產(chǎn)量約3000萬噸，主要集中在巴西、美國；生物柴油年產(chǎn)量約200萬噸，主要集中在德國。生物質能利用方式包括發(fā)電、制氣、供熱和生產(chǎn)液體燃料，將成為應用最廣泛的可再生能源技術。然而，由于農(nóng)業(yè)、林業(yè)、工業(yè)及生活方面的生物質資源狀況非常復雜，缺乏相關的統(tǒng)計資料和數(shù)據(jù)，以及各類生物質能資源間以各種復雜的方式相互影響，因此，生物質的消耗量是最難確定或估
