题目内容
阅读下列短文，回答下列问题。 加拿大某公司建造了一座示范厂，用酒精而不是用硫磺造纸浆。该公司董事长佩蒂说：“这是未来之路，用酒精制造纸浆意味着出现一种清洁、无污染的技术。” 如果在小规模工厂里取得成功的这项技术也能在正式规模的工厂里生产出较便宜的纸浆，它将对纸价产生影响。这项技术还能消除造纸工业常有的臭鸡蛋味——硫化氢的气味。 该公司使用的这种工艺叫ALCELL(即酒精alcohol和纤维素cellulose的合成词)，它使用酒精和水代替硫磺把木材分解成纸浆。这种工艺是加拿大在1972年发明的，以前从来没有实现商品化，但是这家公司希望它能使造纸工业发生彻底变革。 佩蒂说：“建造一座新的纸浆厂要耗资10亿美元，而且它要求木材供应源源不断。如有ALCELL工艺，只要耗资3.5亿美元就能建造一个工厂，并使工厂不停地运转，所需木材供应量较小。”他又说：“那意味着一个工厂一天生产350吨而不是1000吨纸浆。”林业产品分析家邓肯森说：“从环境方面来说，它比较清洁，而且小型厂这个概念将会使建造新纸浆厂变得较容易。”这种工艺取得成功，它将能以较低的成本生产纸浆。 第一段中提到“示范厂”，第二段中提到“小规模工厂”、“正式规模的工厂”，第四段中提到“小型厂”，对文中这四个概念的理解，正确的一项是( )。

Questions 53-56 When did sport begin If sport is, in essence, play, the claim might be made that sprot is much older than humankind for, as we all have observed, the beasts play. Dogs and cats wrestle and play ball games. Fished and birds dance. The apes have simple, pleasurable games. Frolicking infants, school children playing tag, and adult arm wrestlers are demonstrating strong, trans-generational and trans-species bonds with the universe of animals past present and future. Young animals, particularly, tumble, chase, run wrestle, mock, imitate, and laugh( or so it seems) to the point of delighted exhaust. Their play, and ours, appears to serve no other purpose than to give pleasure to the players, and apparently to remove us temporarily form the anguish of life in earnest. Some philosophers have claimed that our playfulness is the most noble part of our basic nature. In their generous conception, play harmlessly and experimentally permits us to put our creative forces, fantasy, and imagination into action. Play is release form the tedious battles against scarcity and decline which are the incessant, and inevitable, tragedies of life. This is a grand conception that excites and provokes. The holders of this view claim that origins of our highest accomplishments-liturgy, literature and law-can be traced to play a impulse which, paradoxically, we see most purely enjoyed by young beasts and children. Our sports, in this rather happy, non-fatalistic view of human nature, are more splendid creations of the non-datable, trans-species play impulse. The best title for the passage is _________
