而否定事实信息题的考察内容则相对单一，一般都是根据段落中的三到四个并列细节进行选项设置，因此同学们只要耐心将选项和原文一一对应找到EXCEPT 或 NOT MENTIONED的内容即可。
Water drawn from the lagoon (the large, shallow body of water between Venice and the Mediterranean Sea) and the canals within the city served many domestic uses such as washing and cooking inventories of even the most modest households list large numbers of buckets, which were emptied and rinsed, the ones used to carry the brackish (somewhat salty) canal water were kept separate from those intended for fresh water.
Still, even serving such needs would have been impossible if the canals of Venice had been extremely polluted. /// The government was obliged to impose controls, and in the early fourteenth century, the Great Council prohibited the washing of all cloth and dyed woolens in the canals, adding that water used for dyeing could not be flushed into the canals.
Henceforth dirty water of that sort was to go into the lagoon. /// Thanks to resistance on the part of the dyers, infractions were many, the law did not reflect common practice. A century later, however, most of the dye works that used blood or indigo (a dark blue dye) had shifted to the periphery of the city, as had all activities “that let off bad odors or smells,” such as butchering.
Blood, carcasses, and spoiled meat were to go into the lagoon. The canals of Venice began to be protected in the name of nascent ecological awareness.
👉According to paragraph 2, how did dyers respond to the controls imposed by the government?
A.They switched from using dyes that let off bad odors or smells to new dyes that smelled much better.
B.They resisted initially but eventually moved most of the dyeing operations outside the city center.
C.They argued that the government did not consider common practice before imposing the controls
D.They started washing cloth and woolens dyed with blood and indigo in the lagoon.
In the thirteenth century, a decision was made to create 50 additional cisterns, primarily in the recently urbanized area at the edge of the city. At the same time, a campaign was launched to repair the existing cisterns.
Expansion of the cistern system stopped during much of the fourteenth century as Venice, like other cities in Europe, suffered from bubonic plague. In the fifteenth century, however, a new program of cistern construction and repair was undertaken.
👉According to paragraph 5, all of the following had an effect on cisterns in Venice from thethirteenth to the fifteenth century EXCEPT
A.the construction of cisterns in other cities in Europe
B.the establishment of programs to construct and repair cisterns
C.the outbreak of bubonic plague
D.the urbanization of an area at the edge of the city
The city of Venice, built on saltwater marshes and crisscrosses by canal, experienced problems with its water supply for most of its history. One fifteenth-century French traveler noted that “in a city in which the inhabitants are in water up to their mouths, they often go thirsty.”How was the community to solve this important problem?
👉Why does the author include the quotation “in a city in which the inhabitants are in water up to their mouths, they often go thirsty.”?
A.To indicate that the French traveled to Venice frequently in the fifteenth century
B.To illustrate the opinion of other Europeans about the water situation in Venice
C.To suggest that the water supply problem of Venice continued well beyond the fifteenth century
D.To emphasize how serious the water problem was in Venice
这道目的题询问的是quotation引言的作用，本质上也是将别人说过的话当做例子来证明作者提出的观点，因此我们也将quotation看做是举例的修辞就可以了。在这里还需要提醒各位一点，如果题干所问的细节内容是例子，那么一定要把例子所在的句子完整的看做是一个例子的整体。因此这道题我们就看做是作者提到One fifteenth-century French traveler noted that “in a city in which the inhabitants are in water up to their mouths, they often go thirsty.”
Much more stringent measures were necessary to guarantee a supply of drinking water, however. In the early centuries of settlement in the lagoon basin, the populations depended on wells on the nearby coastal region. By the ninth century, however, with the increase in population density, cisterns became necessary.
Basically, the cisterns were large, covered pits dug into the ground and lined with clay to hold water. The cisterns were located in the city, but unlike the wells, the cisterns were not supplied with water from the lagoon, they collected rainwater instead. Cisterns became widespread in the growing city.
👉It can be inferred from paragraph 3 that wells on the nearby coastal region
A.were smaller in size than the cisterns located in the city
B.served as a water source for the growing number of cisterns in the city
C.increased in number as the population density increased
D.provided enough water for only a relatively small number of people
题目让我们推理的是有关“沿海地区的水井”的相关信息，那么我们回到原文中去定位可以发现针对wells的信息有两点，一个是population，早年间人们主要靠水井供水，但是9世纪人口增加，cisterns变得必要；一个是from the lagoon，水井的水来自lagoon，cisterns的水来自雨水。
因此这道题的正确答案D就很显而易见了，是通过population的信息推断出来的。A选项其实是迷惑性非常强的选项，因为原文中提到the cisterns were large所以大家可能下意识认为水井的尺寸小，这也是利用了大家的惯性思维从而形成的过度推理的结论，一定要注意避开这类陷阱。
