[单项选择]In ancient Greece athletic festivals were very important and had strong religious associations. The Olympian athletic festival held every four years in honor of Zeus, king of the Olympian Gods, eventually lost its local character, became first a national event and then, after the rules against foreign competitors had been abolished, international. No one knows exactly how far back the Olympic Games go, but some official records date from 776 B. C. The games took place in August on the plain by Mount Olympus. Many thousands of spectators gathered from all parts of Greece, but no married woman was admitted even as a spectator. Slaves, women and dishonored persons were not allowed to complete.

Of all the areas of learning the most important is the development of attitudes.. emotional reactions as well as logical thought processes affect the behavior of most people. "The burnt child fears the fire" is one instance; another is the rise of despots like Hitler. Both these examples also point up the fact that attitudes come from experience. In the one case the experience was direct and impressive; in the other it was indirect and cumulative. The Nazis were influenced largely by the speeches they heard and the books they read.
The classroom teacher in the elementary school is in a strategic position to influence attitudes. This is true partly because children acquire attitudes from those adults whose words are highly regarded by them.
Another reason it is true is that pupils often devote their time to a subject in school that has only been touched upon at home or has possibly never occurred to them before. To a child who had pr

Countries at all levels of
economic development face a similar challenge: to make their industries
competitive in an increasingly integrated global economy. Despite sharing the

developed countries must protect their markets from new competitors. Countries
once governed or still governed by communist parties must prepare their
industries to compete in a global market-driven economy. Developing countries of
Africa, Asia, and Latin America must identify new markets and sources of revenue
to generate industrial growth.
Competition among blocs
Industrial competition in the relatively developed world increasingly takes
place among blocs of countries. Countries within three groups—North America,
Western Europe, and East Asia—cooperate more extensively with each o
A. many countries in East Asia are politically hostile to Japan
B. few countries in this region could match Japan in export
C. the governments are not aware of the necessity
D. there is no agreement on the elimination of trade barriers

Therefore there are critical biological times for language development.
Current reviews of innateness theory are mixed, however, evidence supporting the (43) of some innate abilities is undeniable.
