A great number of species are living in the world. In order to survive, they must belong to a stable food chain. For a food chain to be stable, it must keep layers species. If a species disappears, the food chain breaks, this can cause serious problems. We humans belong t food chain, too. According to one scientist, three hundr trout are needed to support one human for a year. The trout must consume 90,000 frogs. The frogs must eat 2 million grasshoppers, and the grasshoppers require 1,0 tons of grass. Imagine what will happen to us if all gras disappears.

Play and art are alike in that both activities appear superficially at any rate>to lack the compulsion associated with biological necessity. We seem not to have to play in order to survivé; nor are we obviously compelled to paint pictures, compose music, or sculpt statues. Although one can imagine that a man might be forced by S. another to create sómething, it is generally true that art is a voluntary activity, and that creativity_flourishes best (in the absence of compulsion. The same is true óf play. \For, although one might compel a child to play a game\against his will, the game will straightaway lose one of the characteristics)that makes(it play. If it is accepted that both play and art are essentiarty voluntary, it follows that both are generally( 2 )activites. | Although games. can be turned into ways of makinga living by those who are particularly skilful players, (hey do not originate in this way. Although creative productionv may turn out to be financially rewarding, men do not primarily engage in it for the sake of financial gain. Both games and werks,of art stand somewhat outside the ordinary course of life, and 'do not appear to be associated with the immediate satisfaction of wants and appetites. The idea that a novelist, for example, could sit down and write a popular romance for cash with her tongue in her cheek is almost certainly( 3 ).

* Indeed there were severa! "false theories, according to Mr. Popik. Some said New York was the Big Apple because so many desperate people sold apples from carts during *the Great Depression, but the term had existed before that. Others said it was because of the famous apple tree planted in 1647 by Peter Stuyvesant, the last Dutch *governor of the city, which survived for 220 years on the corner of 13th Street and 3rd Avenue, but the history books show this was a "pear tree. It's difficuit to be totally certain where any word or expression first came frcm. But in 1997 the mayor's office informally accepted Mr. Popik's version of events when it added the name "Big Apple Corner" to the spot where Broadway meets West 54th Street. It was here that the long-forgotten racing reporter Mr. FitzGerald lived for the last 30 years of his life. I can't think of any city with a more famous nickname. (注) term: 葉 etymology: 語源 racetrack: 競馬場 ばてい groom: 馬丁(馬の世話係) thoroughbred: サラブレッド(馬の一品種) tourist board:観光局 false theory: 誤った説 なし the Great Depression: 大恐慌 governor: 植民地総督 pear: 梨 問5 Actording to one of the false theories in the 7th paragraph, the governor Sold many apples from carts : planted a famous apple tree ウ、sold many pears from carts エ, planted a famous pear tree
