　　托福阅读背景知识：

　　Some scholars contend that at the beginning of the 14th century, Europe had become overpopulated. By the 14th century frontiers had ceased to expand and internal colonization was coming to an end, but population levels remained high.

　　The Medieval Warm Period ended sometime towards the end of the 13th century, bringing the "Little Ice Age" and harsher winters with reduced harvests. In Northern Europe, new technological innovations such as the heavy plough and the three-field system were not as effective in clearing new fields for harvest as they were in the Mediterranean because the north had poor, clay-like soil.[8] Food shortages and rapidly inflating prices were a fact of life for as much as a century before the plague. Wheat, oats, hay and consequently livestock, were all in short supply. Their scarcity resulted in malnutrition, which increases susceptibility to infections due to weakened immunity. In the autumn of 1314, heavy rains began to fall, which were the start of several years of cold and wet winters.[8] The already weak harvests of the north suffered and the seven-year famine ensued. In the years 1315 to 1317 a catastrophic famine, known as the Great Famine, struck much of North West Europe. It was arguably the worst in European history, perhaps reducing the population by more than 10%.

　　Most governments instituted measures that prohibited exports of foodstuffs, condemned black market speculators, set price controls on grain and outlawed large-scale fishing. At best, they proved mostly unenforceable and at worst they contributed to a continent-wide downward spiral. The hardest hit lands, like England, were unable to buy grain abroad: from France because of the prohibition, and from most of the rest of the grain producers because of crop failures from shortage of labour. Any grain that could be shipped was eventually taken by pirates or looters to be sold on the black market. Meanwhile, many of the largest countries, most notably England and Scotland, had been at war, using up much of their treasury and exacerbating inflation. In 1337, on the eve of the first wave of the Black Death, England and France went to war in what became known as the Hundred Years' War. This situation was worsened when landowners and monarchs such as Edward III of England (r. 1327–1377) and Philip VI of France (r. 1328–1350), raised the fines and rents of their tenants out of a fear that their comparatively high standard of living would decline.

　　The European economy entered a vicious circle in which hunger and chronic, low-level debilitating disease reduced the productivity of labourers, and so the grain output was reduced, causing grain prices to increase. Standards of living fell drastically, diets grew more limited, and Europeans as a whole experienced more health problems.

　　When a typhoid epidemic emerged, many thousands died in populated urban centres, most significantly Ypres (now in Belgium). In 1318 a pestilence of unknown origin, sometimes identified as anthrax, targeted the animals of Europe, notably sheep and cattle, further reducing the food supply and income of the peasantry.
