【正文】 s, samples, rocksThe ocean bottom – a region nearly times greater than the total land area of the Earth – is a vast frontier that even today is largely unexplored and uncharted. Until about a century ago, the deep – ocean floor was pletely inaccessible, hidden beneath waters averaging over 3,6000 meters deep. Totally without light and subjected to intense pressures hundreds of times greater than at the Earth39。s Deep Sea Drilling Project (DSDP). Using techniques first developed for the offshore oil and gas industry, the DSDP39。s surface and drill in very deep waters, extracting samples of sediments and rock from the ocean floor. The Glomar Challenger pleted 96 voyages in a 15 – year research program that ended in November 1983. During this time, the vessel logged 600,000 kilometers and took almost 20,000 core samples of seabed sediments and rocks at 624 drilling sites around the world. The Glomar Challenger39。s voyages, nearly all earth scientists agree on the theories of plate tectonics and continental drift that explain many of the geological processes that shape the Earth. The cores of sediment drilled by the Glomar Challenger have also yielded information critical to understanding the world39。s climate millions of years ago was similar to conditions in outer space(B) it is similar to the ocean floor in being alien to the human environment(C) rock formations in outer space are similar to those found on the ocean floor(D) techniques used by scientists to explore outer space were similar to those used in ocean exploration4.

Most of this surging growth came from natural increase. The depression of the 193039。s, producing a population increase of nearly fifteen percent in the five years from 1951 to 1956. This rate of increase had been exceeded only once before in Canada39。s supported a growth in the population, but the expansion also derived from a trend toward earlier marriages and an increase in the average size of families. In 1957 the Canadian birth rate stood at 28 per thousand, one of the highest in the world. After the peak year of 1957, the birth rate in Canada began to decline. It continued falling until in 1966 it stood at the lowest level in 25 years. Partly this decline reflected the low level of births during the depression and the war, but it was also caused by changes in Canadian society. Young people were staying at school longer, more women were working, young married couples were buying automobiles or houses before starting families, rising living standards were cutting down the size of families. It appeared that Canada was once more falling in step with the trend toward smaller families that had occurred all through the Western world since the time of the Industrial Revolution. Although the growth in Canada39。s was only nine percent). Another large population wave was ing over the horizon. It would be posed of the children who were born during the period of the high birth rate prior to 1957.10. What does the passage mainly discuss? C(A) Educational changes in Canadian society.(B) Canada during the Second World War(C) Population trends in postwar Canada(D) Standards of living in Canada11. According to the passage, when did Canada39。s(D) In 196612. The word five in line 2 refers to A(A) Canadians(B) Years(C) Decades(D) Marriages13. The word surging in line 3 is closest in meaning to C(A) new(B) extra(C) accelerating(D) surprising14. The author suggests that in Canada during the 195039。s attitude toward the claims made by advocates of health foods? D(A) Very enthusiastic(B) Somewhat favorable(C) Neutral(D) SkepticalQuestions 3140There are many theories about the beginning of drama in ancient Greece. The one most widely accepted today is based on the assumption that drama evolved from ritual. The argument for this view goes as follows. In the beginning, human beings viewed the natural forces of the world, even the seasonal changes, as unpredictable, and they sought through various means, to control these unknown and feared powers. Those measures which appeared to bring the desired results were then retained and repeated until they hardened into fixed rituals. Eventually stories arose which explained or veiled the mysteries of the rites. As time passed some rituals were abandoned, but the stories, later called myths, persisted and provided material for art and drama. Those who believe that drama evolved out of ritual also argue that those rites contained the seed of theater because music, dance, masks, and costumes were almost always used. Furthermore, a suitable site had to be provided for performances, and when the entire munity did not participate, a clear division was usually made between the acting ar
