Passage TwoQuestions 26 to 30 are based on the following passage.Certain animals and plants develop characteristics(特性)that help them cope with their environment better than others of their kind. This natural biological process is called adaptation(适应性). 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 for adapting. They may adapt in their structure，function，and genetics(遗传素质)；in their development and production of the young；and in other respects. An organism may create its own 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______.

Passage TwoThe lion may be the most famous of all the predators of Africa, but one of the most fascinating is the wild dog. Wild dogs are fairly small, averaging seventy pounds, with round, fanlike ears that look too big for their heads. They have shaggy brown coats with scattered patches of white. One of these animals by itself looks harmless or even comical. But when they band together, in packs of up to forty, the wild dogs become dangerous predators that tirelessly run down and kill animals that are many times their own size.Wild dogs have to be good hunters in order to feed their large families; a single female can have as many as sixteen pups at a time. But usually only one female in a pack breeds at a time, and all the pack members help to care for the young. At first, the pups feed on their mother's milk. Then the other dogs begin to bring back meat from the kill, carrying it in their stomachs and throwing it up when the pups come running to them to beg for food. Finally, the young dogs begin to go along on hunts. At this time one of the most striking differences between wild dogs and lions can be seen. When a pride of lions makes a kill, the adult males always eat their fill first. But the wild dogs let the pups feed first, even when they are still too young to really help in making the kill.36. A good title for this passage would be ______.
