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 （凱亞巴布高原） 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 （特權） 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 （饑餓） 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.

1.The destruction of the environment of the Kaibab resulted from    

A．interfering with natural cycle of forest life

B．turning the forest into cultivated land

C．forest fires caused by man’s carelessness

D．cutting the trees for building materials

2."Engelmann spruce"（Para. 2） is most likely the name of .

A．an animal         B．a tree            C．a mountain        D．a game

3.The number of the deer in the Kaibab had increased enormously in     years’ time.

A．25               B．6                C．12               D．18

4.Years later, large numbers of deer in the Kaibab died mainly because of .

A．the cold                              B．the organized kill

C．the poor management                    D．the shortage of food

4.D

【解析】

試題分析：本文通過講述北亞利桑那的凱亞巴布高原的森林環境是怎樣遭到破壞的例子說明人類對自然生態圈的干涉導致環境破壞。

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.可知選答案A。

2.從第二段中The Kaibab had a storybook forest of large sized pine, Douglas fir, white fir, blue and Engelmann spruce，and連接并列結構，前面所列舉的樹木的名字，可猜出Engelmann spruce也是一種樹。

3.由文中第三段中的敘述 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 ，從而得知1924－1906＝18。

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。
