Question

Modern man has cleared the forests for farmland and for wood, and has also carelessly burned them. More than that, though, he has also interfered （干涉） with the invisible bonds between the living things in the forests. There are many examples of this kind of destruction. The harmfulness of man’s interference can be seen in what happened many years ago in the forest of the Kaibab plateau （凯亚巴布高原） of northern Arizona. Man tried to improve on the natural web of forest life and destroyed it instead.
The Kaibab had a storybook forest of large sized pine, Douglas fir, white fir, blue and Engelmann spruce. In 1882 a visitor noted, "We, who ... have wandered through its forests and parks, have come to regard it as the most enchanting region it has ever been our privilege （特权） to visit.” This was also the living place of the Rocky Mountain mule deer. Indians hunted there every autumn to gather meat and skins. The forest also had mountain lions, timber wolves and bobcats that kept the deer from multiplying too rapidly.
Then, in 1906, President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was forbidden. Government hunters started killing off the deer’s enemies. In 25 years’ time, 6,250 mountain lions, wolves and bobcats were killed. Before the program, there were about 4,000 deer in the Kaibab, by 1924, there were about 100,000.
The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer was permitted again. This caused a slight decrease in the deer herd （鹿群），but a far greater loss resulted from starvation （饥饿） and disease. Some 60 percent of the deer herd died in two winters. By 1930 the herd had dropped to 20,000 animals. By 1942 it was down to 8,000.

解析试题分析：本文通过讲述北亚利桑那的凯亚巴布高原的森林环境是怎样遭到破坏的例子说明人类对自然生态圈的干涉导致环境破坏。
【小题1】第一段第二句More than that, though, he has also interfered （干涉） with the invisible bonds between the living things in the forests. There are many examples of this kind of destruction.可知选答案A。
【小题2】从第二段中The Kaibab had a storybook forest of large sized pine, Douglas fir, white fir, blue and Engelmann spruce，and连接并列结构，前面所列举的树木的名字，可猜出Engelmann spruce也是一种树。
【小题3】由文中第三段中的叙述 in 1906, President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was forbidden及there were about 4,000 deer in the Kaibab by 1924 ，从而得知1924－1906＝18。
【小题4】由第四段第一．二句The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer was permitted again可知。
