考题 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______.A. help others of their kind get food,shelter and other things neededB. get into the biological process of adaptationC. become better adapted to the environments than others of their kindD. lead to the evolution and production of more and more organisms

考题 资料:Anything that affects the smooth flow of information is known as noise. This might be, for example, the language used,an in appropriate use of technology or the different levels of skill and knowledge of the sender and receiver. For example, every day in the press and on TV, consumers are bombarded with often confusing or contradictory information about the health benefits or risks associated with different foods. Consumers may not have enough understanding or information to judge between conflicting messages. It is therefore not surprising that many people do not hear these messages and switch off. A company has to overcome a considerable amount of direct noise caused by the earlier negative press articles. By not responding to these immediately or correcting with facts, consumers are confused and the company loses credibility with the press and the public. To achieve its vision and encourage consumers to eat turkey all year round, BM Company needs to give people more information in a way they can easily understand. It has there closed to highlight key facts about the products as the foundation for many of its messages. Why don;t many people hear the message that the companies want them to know?

考题 问答题Practice 3  A newspaper is much more than a business; it is an institution. It reflects and influences the life of a community; it may affect even wider destinies.  It is, in its way, an instrument of government. It plays on the minds and consciences of man. It may educate, stimulate, assist, or it may do the opposite. It has, therefore, a moral as well as a material existence, and its character and influence are in the main determined by the balance of these two factors. It may make profit or power its first object, or it may conceive itself as fulfilling a higher and more exacting function.  Character is a subtle affaire, and has many shades and sides. It is not a thing to be much talked about, but rather to be felt. It is the slow deposit of past actions and ideas.  At the perils of its soul, a newspaper must see that the news it supplies is not tainted. Neither in what it gives, nor in what it does not give, nor in the mode of presentation, must the unclouded face of truth suffer wrong. Comment is free, but facts are sacred. “Propaganda,” so called, by this means is hateful. The voice of opponents no less than that of friends has a right to be heard. Comment also is justly subject to a self-imposed restraint. It is well to be frank; it is even better to be fair. This is an ideal. Achievement in such matters is hardly given to man. Perhaps none of us can attain to it in the desirable measure. We can but try, ask pardon for shortcomings, and there leave the matter.  One of the virtues, perhaps the chief virtue, of a newspaper is its independence. Whatever its position or character, it should have a soul of its own.  That is the path of self-respect—it is also the path of success. And what a work it is! How multiform, how responsive to every need—and every incident of life! What illimitable possibilities of achievement and of excellence!  To the man, whatever his place on the paper, nothing should satisfy short of the best. It is here that ability counts and that character counts, and it is on these that a newspaper, if it is to be worthy of its power and duty, must rely.
