Adaptation of Living Things

Certain animals and plants develop characteristics that help them cope with their environment better than others of their kind. This natural biological process is called adaptation. Among the superior characteristics developed through adaptation are those that may help in getting food or shelter, in providing protection, and in producing and protecting the young. That results in the evolution of more and more organisms that are better fitted to their environments.

Each living thing is adapted to its way of life in a general way, but each is adapted especially to its own distinct class. A plant, for example, depends upon its roots to fix itself firmly and to absorb water and inorganic chemicals. It depends upon its green leaves for using the sun's energy to make food from inorganic chemicals. These are general adaptations, common to most plants. In addition, there are special adaptations that only certain kinds of plants have.

Many animals have adaptations that help them escape from their enemies. Some insects are hidden by their body color or shape, and many look like a leaf or a little branch. The coats of deer are colored to mix with the surroundings. Many animals have the ability to remain completely still when an enemy is near.

Organisms have a great variety of ways of adapting. They may adapt in their structure, function, and genetics; in their development and production of the young; and in other respects. An organism may create its won environment, as do warm-blooded mammals, which have the ability to adjust body heat exactly to maintain their ideal temperature despite changing weather. Usually adaptations are an advantage, but sometimes an organism is so well adapted to a particular environment that, if conditions change, it finds it difficult or impossible to readapt to the new conditions.

Some plants and animals develop superior characteristics so that they may ______.

A．help others of their kind get food, shelter and other things needed

B．survive even in extremely severe conditions'

C．become better adapted to the environments San others of their kind

D．result in the evolution and production of more intelligent organisms

第7题

Large animals living in the desert have developed a number of adaptations for reducing the

effects of extreme heat. One adaptation is to be light in color, and to reflect rather than absorb the sun's rays. Desert animals also depart from other animals' normal practice of maintaining a constant body temperature. Instead of trying to keep down the body temperature deep inside the body, which would involve the loss of water and energy, large desert animals allow their temperatures to rise to what would normally be fever height, and temperatures as high as 46 degrees Celsius have been measured in grant's gazelles. The over-heated body then cools down during the cold desert night, and indeed the temperature may fall unusually low by dawn, as low as 34 degrees Celsius in the camel. This is an advantage since the heat of the first few hours of daylight is absorbed in warming up the body, and an excessive buildup of heat does not begin until well into the day.

Another strategy of large desert animals is to tolerate the loss of body water to a point that would be fatal for non-adapted animals. The camel can lose up to 30% of its body weight as water without harm to itself, whereas human beings die after losing only 12%-13% of their body weight. An equally important adaptation is the ability to recover this water loss at one drink. Desert animals can drink massive volumes of water in a short time, and camels have been known to drink over 100 liters in a few minutes. A person who severely loses water, on the other hand, cannot drink enough water for recovery at one session, because the human stomach is not sufficiently big and because a too rapid mixing of the body liquid with water causes death from water intoxication. The tolerance of water loss is of obvious advantage in the desert, as animals do not have to remain near a water hole but can obtain food by searching quite a few distant places. Desert-adapted animals have the further ability to feed normally when extremely thirsty: it is a common experience in people that appetite is lost even under conditions of moderate thirst.

What does the passage mainly discuss？

A．How large desert animals adapt to the environment.

B．Weather conditions in the desert.

C．Human use of large desert animals.

D．Health problems of large desert animals.
