【单选题】

The growth of population during the past few centuries is no proof that population will continue to grow straight upward toward infinity and doom. On the contrary, demographic history offers evidence that population growth has not been at all constant. According to paleo-ecologist Edward Deevey, the past million years show three momentous changes. The first, a rapid increase in population around one million B. C., followed the innovations of tool- and tool-using. But when the new power from the use of tools had been exploited, the rate of world population growth fell and became almost stable.
The next rapid jump in population started perhaps 10,000 years ago, when men began to keep herds, plow and plant the earth. Once again when initial productivity gains had been absorbed, the rate of population growth abated.
These two episodes suggest that the third great change, the present rapid growth, which began in the West between 250 and 350 years ago, may also slow down when, or if technology begins to yield fewer innovations. Of course, the current knowledge revolution
may continue without foreseeable end. Either way contrary to popular belief in constant geometric growth--population can be expected in the long nm to adjust to productivity.
What can be concluded when the current tide of knowledge revolution ebbs

A.
Productivity will rise.
B.
Productivity will receive no impact.
C.
Population growth will slow down.
D.
Population growth will become accelerate

【单选题】Some birds like to sit on a sheep because (). A.they can eat its parasites B.they enjoy travelling with the sheep C.they depend on the sheep for existence D.they find the position most comfortable

A.
Most of the animals have little connection with animals of a different kind, unless they hunt them for food. Sometimes, however, two kinds of animals come together in a partnership (伙伴关系) which is good for both of them. You may see some birds sitting on the backs of sheep. This is not because they want a ride, but because they find easy food in the parasites (寄生虫) on sheep. The sheep allow the lairds to do so because they move the cause of discomfort. So although they can live without each other, they do better together.
B.
Sometimes an animal has a plant partner. The relationship develops until the two partners can not live without each other. This is so in the corals (珊瑚) of the sea. In their skins there are tiny plants which act as "dustmen", taking some of the waste products from the corals and giving in return oxygen which the animal needs to breathe. If the plants are killed, or are even prevented from receiving light so that they cannot live normally, the corals will die.
