Massive changes in all of the world’s deeply cherished sporting habits are underway. Whether it’s one of London’s parks full of people playing softball, and Russians taking up rugby, or the Superbowl rivaling the British Football Cup Final as a televised spectator event in Britain, the patterns of players and spectators are changing beyond recognition. We are witnessing a globalization of our sporting culture.

That annual bicycle race, the Tour de France, much loved by the French is a good case in point. Just a few years back it was a strictly continental affair with France, Belgium and Holland, Spain and Italy taking part. But in recent years it has been dominated by Colombian mountain climbers, and American and Irish riders. The people who really matter welcome the shift toward globalization. Peugeot, Michelin and Panasonic are multi-national corporations that want worldwide returns for the millions they invest in teams. So it does them literally a world of good to see this unofficial world championship become just that.

This is undoubtedly an economic-based revolution we are witnessing here, one made possible by communications technology, but made to happen because of marketing considerations. Sell the game and you can sell Coca Cola or Budweiser as well.

The skilful way in which American football has been sold to Europe is a good example of how all sports will develop. The aim of course is not really to spread the sport for its own sake, but to increase the number of people interested in the major money-making events. The economics of the Superbowl are already astronomical. With seats at US $125, gate receipts alone were a staggering $10,000,000. The most important statistic of the day, however, was the $100,000,000 in TV advertising fees. Imagine how much that becomes when the eyes of the world are watching.

So it came as a terrible shock, but not really as a surprise, to learn that some people are now suggesting that soccer change from being a game of two 45-minute halves, to one of four 25-minute quarters. The idea is unashamedly to capture more advertising revenue, without giving any thought for the integrity of a sport which relies for its essence on the flowing nature of the action.

Moreover, as sports expand into world markets, and as our choice of sports as consumers also grows, so we will demand to see them played at a higher and higher level. In boxing we have already seen numerous, dubious world title categories because people will not pay to see anything less than a "World Title" fight, and this means that the title fights have to be held in different countries around the world!

People want to see higher-level sports competitions mainly because（）

A. they become more professional than ever

B. they regard sports as consumer goods

C. there exist few world-class championships

D. sports events are exciting and stimulating

The world is undergoing tremendous changes. The rise of globalization, both an economic and cultural trend that has swept throughout the world, has forged new ground as we enter the 21st century. But are the effects of globalization always positive Some say no.

Michael Tenet, head of the International Institute for Foreign Relations in Atlanta, is worried about current resentment throughout the world toward the rise of globalization. "Ever since the 1980s and the economic collapse of the Asian Tigers in the late 1990s, there has been a re-evaluation of the role of globalization as a force for good," he said. "Incomes in many countries has declined and the gap between the most rich and the most poor has been aggravated. Without further intervention by governments, we could see a tragedy expressed in an increased level of poverty throughout the Latin America and Asia. " Yet George Frank, an influential economist who works on Wall Street, sees no such danger. "Economic liberalization, increased transparency and market-based reforms have positive effect in the long run, even if market mechanisms can produce short-term destabilization problems," he said. "What is most important is that barriers to trade continue to fall so that active competition for consumer goods reduces prices and in turn raises the average level of income. "

Others feel that globalization’s cultural impact may be more important than its economic implications. Janice Yawee, a native of Africa, feels ply that globalization is undermining her local culture and language. "Most of the world’s dialects will become extinct under globalization. We’re paving the world with McDonald’s and English slang. It tears me up inside," she said.

Governments of different countries have had mixed responses to the wave of globalization. The United States is generally seen as an active proponent of greater free trade, and it certainly has enormous cultural influence by virtue of its near monopoly on worldwide entertainment. But other countries, most notably in Europe and developing nations, have sought to reduce the impact that globalization has on their domestic affairs.

"When I was a boy we had very little to speak of," says one Singaporean resident. "Now our country has developed into a booming hub for international finance. " Others, however, are not so optimistic. "Globalization is an evil force that must be halted," a union official at a car plant in Detroit recently commented, "It’s sucking away jobs and killing the spirit of our country.
