Lesson 6 The Sporting SpiritI am always amazed when I hear people saying that sport creates goodwill between the nations, and that if only the common peoples of the world could meet one another at football or cricket, they would have no inclination to meet on the battlefield. Even if one didn't know from concrete examples (the 1936 Olympic Games, for instance) that international sporting contests lead to orgies of hatred, one could deduce it from general principles. Nearly all the sports practised nowadays are competitive. You play to win, and the game has little meaning unless you do your utmost to win. On the village green, where you pick up sides and no feeling of local patriotism is involved, it is possible to play simply for the fun and exercise: but as soon as the question of prestige arises, as soon as you feel that you and some larger unit will be disgraced if you lose, the most savage combative instincts are aroused. Anyone who has played even in a school football match knows this. At the international level sport is frankly mimic warfare. But the significant thing is not the behaviour of the players but the attitude of the spectators: and, behind the spectators, of the nations. who work themselves into furies over these absurd contests, and seriously believe--at any rate for short periods--that running, jumping and kicking a ball are tests of national virtue. 音频下载：http://b.tonxoo.com/upload/en/模仿音频/07_L006.mp3Lesson 7 Bats Not all sounds made by animals serve as language, and we have only to turn to that extraordinary discovery of echo-location in bats to see a case in which the voice plays a strictly utilitarian role. To get a full appreciation of what this means we must turn first to some recent human inventions. Everyone knows that if he shouts in the vicinity of a wall or a mountainside, an echo will come back. The further off this solid obstruction the longer time will elapse for the return of the echo. A sound made by tapping on the hull of a ship will be reflected from the sea bottom, and by measuring the time interval between the taps and the receipt of the echoes the depth of the sea at that point can be calculated. So was born the echo-sounding apparatus, now in general use in ships. Every solid object will reflect a sound, varying according to the size and nature of the object. A shoal of fish will do this. So it is a comparatively simple step from locating the sea bottom to locating a shoal of fish. With experience, and with improved apparatus, it is now possible not only to locate a shoal but to tell if it is herring, cod, or other well-known fish, by the pattern of its echo. A few years ago it was found that certain bats emit squeaks and by receiving the echoes they could locate and steer clear of obstacles--or locate flying insects on which they feed. This echo-location in bats is often compared with radar, the principle of which is similar. 音频下载：http://b.tonxoo.com/upload/en/模仿音频/08_L007.mp3Lesson 8 Trading Standards Chickens slaughtered in the United States, claim officials in Brussels, are not fit to grace European tables. No, say the Americans: our fowl are fine, we simply clean them in a different way. These days, it is differences in national regulations, far more than tariffs, that put sand in the wheels of trade between rich countries. It is not just farmers who are complaining . An electric razor that meets the European Union’s safety standards must be approved by American testers before it can be sold in the United States, and an American-made dialysis machine needs the EU’s okay before it hits the market in Europe. As it happens, a razor that is safe in Europe is unlikely to electrocute Americans. So, ask businesses on both sides of the Atlantic, why have two lots of tests where one would do? Politicians agree, in principle, so America and the EU have been trying to reach a deal which would eliminate the need to double-test many products. They hope to finish in time for a trade summit between America and EU on May 28th. Although negotiators are optimistic, the details are complex enough that they may be hard-pressed to get a deal at all. Why? One difficulty is to construct the agreements. The Americans would happily reach one accord on standards for medical devices and then hammer out different pacts covering, say, electronic goods and drug manufacturing. The EU-following fine continental traditions—wants agreement on general principles, which could be applied to many types of products and have extended to other countries. 音频下载：http://b.tonxoo.com/upload/en/模仿音频/09_L008.mp3Lesson 9 Royal Espionage Alfred the Great acted as his own spy, visiting Danish camps disguised as a minstrel. In those days wandering minstrels were welcome everywhere. They were not fighting men, and their harp was their passport. Alfred had learned many of their ballads in his youth, and could vary his programme with acrobatic tricks and simple conjuring. While Alfred's little army slowly began to gather at Athelney, the king himself set out to penetrate the camp of Guthrum, the commander of the Danish invaders. These had settled down for the winter at Chippenham: thither Alfred went. He noticed at once that discipline was slack: the Danes had the self-confidence of conquerors, and their security precautions were casual. They lived well, on the proceeds of raids on neighboring regions. There they collected women as well as food and drink, and a life of ease had made them soft. Alfred stayed in the camp a week before he returned to Athelney. The force there assembled was trivial compared with the Danish horde. But Alfred had deduced that the Danes were no longer fit for prolonged battle : and that their commissariat had no organization, but depended on irregular raids. So, faced with the Danish advance, Alfred did not risk open battle but harried the enemy. He was constantly on the move, drawing the Danes after him. His patrols halted the raiding parties: hunger assailed the Danish army. Now Alfred began a long series of skirmishes--and within a month the Danes had surrendered. The episode could reasonably serve as a unique epic of royal espionage!音频下载：http://b.tonxoo.com/upload/en/模仿音频/10_L009.mp3
Lesson 10 Silicon Valley Technology trends may push Silicon Valley back to the future. Carver Mead, a pioneer in integrated circuits and a professor of computer science at the California Institute of Technology, notes there are now workstations that enable engineers to design, test and produce chips right on their desks, much the way an editor creates a newsletter on a Macintosh. As the time and cost of making a chip drip to a few days and a few hundred dollars, engineers may soon be free to let their imaginations soar without being penalized by expensive failures. Mead predicts that inventors will be able to perfect powerful customized chips over a weekend at the office—spawning a new generation of garage start-ups and giving the U.S. a jump on its foreign rivals in getting new products to market fast. ‘We’ve got more garages with smart people,’ Mead observes. ‘We really thrive on anarchy.’ And on Asians. Already, orientals and Asian Americans constitute the majority of the engineering staffs at many Valley firms. And Chinese, Korean, Filipino and Indian engineers are graduating in droves from California’s colleges. As the heads of next-generation start-ups, these Asian innovators can draw on customs and languages to forge tighter links with crucial Pacific Rim market. For instance, Alex Au, a Stanford Ph.D. from Hong Kong, has set up a Taiwan factory to challenge Japan’s near lock on the memory-chip market. India-born N. Damodar Reddy’s tiny California company reopened an AT&T chip plant in Kansas City last spring with financing from the state of Missouri. Before it becomes a retirement village, Silicon Valley may prove a classroom for building a global business.
