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 dishonoured persons were not allowed to compete. The exact sequence of events is uncertain, but events included boy's gymnastics, boxing, wrestling, horse racing and field events, though there were fewer sports involved than in the modern Olympic Games.
On the last day of the Games, all the winners were honoured by having a ring of holy olive leaves placed on their heads. So great was the honour that the winner of the foot race gave his name to the year of his victory. Although Olympic winners received no prize money, they were, in fact, richly rewarded by their state authorities. How their results compared with modern standards, we unfortunately have no means of telling.
After an uninterrupted history of almost 1200 years, the Games were suspended by the Romans in 394 A.D. They continued for such a long time because people believed in the philosophy behind the Olympics: the idea that a healthy body produced a healthy mind, and that the spirit of competition in sports and games was preferable to the competition that caused wars. It was over 1500 years before another such international athletic gathering took place in Athens in 1896.
Nowadays, the Games are held in different countries in turn. The host country provides vast facilities, including a stadium, swimming pools and living accommodation, but competing countries pay their own athletes' expenses.
The Olympics start with the arrival in the stadium of a torch, lighted on Mount Olympus by the sun's rays. It is carried by a succession of runners to the stadium. The torch symbolized the continuation of the ancient Greek athletic ideals, and it burns throughout the Games until the closing ceremony. The well-known Olympic flag, however, is a modern conception: the five interlocking rings symbolize the uniting of all five continents participating in the Games.

A.were merely national athletic festivals

C.had rules which put foreign participants in s disadvantageous position

A.warm,cool and cold
B.rise,mount and ascend

It is hard not to get the message. The virtues of physical fitness are shown on magazine covers, postage stamps, and television ads for everything from beauty soaps to travel books. Exercise as a part of daily life did not catch on until the late 1960s when research by military doctors began to show the health benefits of doing regular physical exercises. Growing publicity (宣专) for races held in American cities helped fuel a strong interest in the ancient sport of running. Although running has leveled off in recent years as Americans have discovered equally rewarding and sometimes safer forms of exercise, such as walking and swimming, running remain the most popular forms of exercise.
As the popularity of exercise continues to mount, so does scientific evidence of its health benefits. The key to fitness is exercising the major muscle groups vigorously (强有力地) enough to approximately double the heart rate and keep it doubled for 20 to 30 minutes at a time. Doing such physical exercises three times of more a week will produce considerable improvements in physical health in about three months.
According to the passage, what was the percentage of American adults doing regular physical exercises two years ago? ()
A.About 70%.
B.Nearly 60%.
C.Almost 50%.
D.More than 12%.
People pondering the origin of language for the first time usually arrive at the conclusion that it developed gradually as a system of conventionalised grunts, hisses, and cries and must have been a very simple affair in the beginning. But when we observe the language behavior. of what we regard as primitive cultures, we find it strikingly elaborate and complicated. Stefansson, the explorer, said that "In order to get along reasonably well an Eskimo must have at the tip of his tongue a vocabulary of more than 10,000 words, much larger than the active vocabulary of an average businessman who speaks English. Moreover these Eskimo words are far more highly inflected than those of any of the well-known European languages, for a single noun can be spoken or written in several hundred different forms, each having a precise meaning different from that of any other. The forms of the verbs are even more numerous. The Eskimo language is, therefore, one of the most difficult in the world to learn, with the result that almost no traders or explorers have even tried to learn it. Consequently there has grown up, an intercourse between Eskimos and whites, a jargon similar to the pidgin English used in China, with a vocabulary of from 300 to 600 uninflected words, most of them derived from Eskimo but some derived from English, Danish, Spanish, Hawaiian and other languages. It is this jargon which is usually referred to by travelers as 'the Eskimo language'. And Professor Thalbitzer of Copenhagen, who did take the trouble to learn Eskimo, seems to endorse the explorer's view when he writes: "The language is polysynthetic. The grammar is extremely rich in flexional forms, the conjugation of a common verb ending. For the declension of a noun there are 150 suffixes (for dual and plural, local cases, and possessive flexion). The derivative endings effective in the vocabulary and the construction of sentences or sentence-like words a mount to at least 250. Not withstanding all these constructive peculiarities, the grammatical and synthetic system is remarkably concise and, in its own way, logical."
The size of the Eskimo language spoken by most whites is ______.
A.spoken in English, Denmark, Spain, and Hawaii
B.less than the size of the language spoken by Eskimos
C.inestimable
D.irrelevant
level of carbon dioxide, CO2, in the atmosphere has important effect on climatic change. Most of the Earth' s incoming energy is short-wavelength radiation, which tends to pass through atmospheric CO2 easily. The Earth, however, reradiates much of the received energy as a long-wavelength radiation, which CO2 absorbs and then remits toward the Earth. This phenomenon, known as the greenhouse effect, can result in an increase in the surface temperature of a planet. An extreme example of the effect is shown by the Venus, a planet covered by heavy clouds composed mostly of CO2, whose surface temperatures have been measured at 430℃. If the CO2 content of the atmosphere is reduced, the temperature falls. According to one respectable theory, if the atmospheric CO2 concentration were halved, the Earth would become completely covered with ice. Another equally respectable theory, however, states that a halving of the C02 concentration would lead only to a reduction in global temperatures of 3℃.
If, because of au increase in forest fires or volcanic activity, the CO2 content of the atmosphere increased, a warmer climate would be produced. Plant growth, which relies on both the warmth and the availability of CO2, would probably increase. As a consequence, plants would use more and more CO2. Eventually CO2 levels would diminish and the climate, in turn, would become cooler. With reduced temperatures many plants would die; CO2 would thereby be returned to the atmosphere and gradually the temperatures would rise again. Thus, if this process occurred, there might be a long-term oscillation in the amount of CO2 present in the atmosphere, with regular temperature increases and decreases of a set magnitude.
Some climatologists argue that the burning of fossil fuels has raised the level of CO2 in the atmosphere and has caused a global temperature rise of at least 1℃. But a supposed global temperature rise of 1℃ may in reality be only several regional temperature increases, restricted to areas where there are many meteorological stations and caused simply by shifts in the pattern of atmospheric circulation. Other areas, for example the Southern Hemisphere oceanic zone, may be experiencing an equivalent temperature decreases that is unrecognized because of the shortage of meteorological recording stations.
The passage supplies information for answering which of the following questions?
A.Why are projections of the effects of changes in water vapor levels on the climate so inaccurate?
B.What are the steps in the process that takes place as CO2 absorbs long-wavelength radiation?
C.How might our understanding of the greenhouse effect be improved if the burning of fossil fuels were decreased?
D.What might cause a series of regular increases and decreases in the amount of CO2 in the atmosphere?
