听力原文： Man is a land animal,but he is also closely tied to the sea.Throughout history the sea has served the needs of man.The sea has provided man with food and a convenient way to travel to many parts of the world. Toady,experts believe that nearly two-thirds of the world's population live within eighty kilometers of the seacoast.In the modem technological world,the sea offers many resources to help mankind survive.Resources on land are beginning to grow less.The sea,however,still offers hope to supply many of man's needs in the future.The riches of the sea yet to be developed by man's technology are impressive.Oil and gas explorations have existed for nearly thirty years.Valuable amounts of minerals such as iron,copper exist on the ocean floor.Besides oil and gas,the seas may offer new sources of energy.For example,warm temperature of the ocean can be used as the steam in a steamship.Sea may also offer a source of energy as electricity for mankind.Technology is enabling man to explore even deeper under the sea.It is obvious that the technology to harvest the sea continues to improve.By the 2050,experts believe that the problems to explore the food, minerals and energy resources of the sea will have been largely solved.
What do we learn about the sea in the modem technological world？
A．It is the largest supplier of valuable minerals.
B．It will disappear in about thirty years.
C．It is beginning to grow smaller and smaller.
D．It offers many resources to help mankind survive.

Not content with its doubtful claim to produce cheap food for our own population, the factory farming industry also argues that "hungry nations are benefiting from advances made by the poultry(家禽) industry". In fact, rather than helping the fight against malnutrition(营养不良) in "hungry nations", the spread of factory farming has, inevitably aggravated the problem.
Large-scale intensive meat and poultry production is a waste of food resources. This is because more protein has to be fed to animals in the form. of vegetable matte than can ever be recovered in the form. of meat. Much of the food value is lost in the animal' s process of digestion and cell replacement. Neither, in the case of chicken, can one eat feathers, blood, feet or head. In all, only about 44% of the live animal fits to be eaten as meat.
This means one has to feed approximately 9～10 times as much food value to the animal than one can consume from the carcass. As a system for feeding the hungry, the effects can prove disastrous. At times of crisis, grain is the food of life.
Nevertheless, the huge increase in poultry production throughout Asia and Africa continues. Normally British or US firms are involved. For instance, an American based multinational company has this year announced its involvement in projects in several African countries. Britain's largest suppliers of chickens, Ross Breeder, are also involved in projects all over the world.
Because such trade is good for exports, Western governments encourage it. In 1979, a firm in Bangladesh called Phoenix Poultry received a grant to set up a unit of 6,000 chickens and 18,000 laying hens. This almost doubled the number of poultry kept in the country all at once.
But Bangladesh lacks capital, energy and food and has large numbers of unemployed. Such chicken-raising demands capital for building and machinery, extensive use of energy resources for automation, and involves feeding chickens with potential famine- relief protein food. At present, one of Bangladesh' s main imports is food grains, because the country is unable to grow enough food to feed its population. On what then can they possibly feed the chicken？
In this passage the author argues that______。
A. efficiency must be raised in the poultry industry
B. raising poultry can provide more protein than growing grain
C. factory farming will do more harm than good to developing countries
D. hungry nations may benefit from the development of the poultry industry

Dutch traders brought 20 Africans to Jamestown, Virginia, as early as 1619, however, throughout the 17 th century the number of Africans in the English mainland colonies grew very slowly. At that time, colonists used two other sources of unfree labor: Native American slaves and European indentured servants.
During those years, every colony had some Native American slaves, but their number was limited. Indian men avoided performing agricultural labor, because they viewed it as women' s work, and colonists complained that they were too "haughty". The more important was that the settlers found it more convenient to sell Native Americans captured in war to planters in the Caribbean than to turn them into slaves, because they often resisted and it was not hard for the slaves to escape. Later, the policy of killing Indians or driving them away from white settlements was proposed and it contradicted with their widespread employment as slaves.
The other form. of labor was the white indentured servitude. Most indentured servants consisted of poor Europeans. Desiring to escape tough conditions in Europe and take advantage of fabled opportunities in America, they traded three to seven years of their labor in exchange for the transatlantic passage. At first, it was mainly English who were the white indentured servitude but later increasingly Irish, Welsh, and German joined. They were essentially temporary slaves and most of them served as agricultural workers although some, especially in the North, were taught skilled trades. During the 17th century, they performed most of heavy labor in the Southern colonies and also consisted of the bulk of immigrants to those colonies.
At the end of the 17 th century, in order to meet the labor need, landowners in America turned to African slaves. During the late 17th and 18th centuries, thanks to the dominant position of England in terms of naval superiority, English traders (some of whom lived in English America) transported millions of Africans across the Atlantic. And the transatlantic slave trade produced one of the largest forced migrations in history, blacks (the great majority of whom were slaves) increasing from about 7 percent of the American population in 1680 to more than 40 percent by the middle of the 18th century.
Which of the following was true of the slavery in America？
A．The colonists sold African Americans to planters in the Caribbean.
B．Native American slaves performed agricultural labor.
C．During the 17th century, the white indentured servitude was the main labor in the Southern colonies.
D．It was at the end of the 17th century that African people began to be brought to America.

Kitchen Design
Over the years economic, social and technological factors have influenced the design of kitchens. Since it is often used simultaneously by both family members as well as guests, the kitchen requires not only a glamorous look but a practical one. Also, the design elements must meet the needs of the modern family.
Environmental concerns have had an enormous impact on kitchen design. This concern includes recycling of household material, as well as energy efficient appliances and the purity of both water and air. Research shows that up to 85 percent of the population is concerned about what might be in their drinking water. They are also often dissatisfied with the taste and odor of what comes out of their tap. This is why it's important to consider adding a water filter system.
The character of today's kitchen is very different from the way it was thirty years ago. There's more sophistication in food preparation, and more technological help with cooking and clean-up.
When choosing cabinets, first consider the style. Use the architectural style. of your house as a guide. Because cabinets are a big investment, it is best to choose quality. Popular styles in kitchen cabinets are framed panel doors with raised or recessed panels of wood, cabinet fronts with glass panes, or simple slab doors in a rich painted or laminated finish. Cabinet pulls, don't be afraid to mix and match styles.
Because many of today's kitchens consist of two or more cooks sharing in the meal preparation, there is a need for more counter space, cook tops and sinks. Although lifestyles are changing, the primary function of the kitchen as an area for preparing food has remained unchanged. The sink remains one of the most used areas in the kitchen as well as an important decorative statement.
Appliance technology is moving at a very fast pace. Choosing what type of appliances as well as how many will depend on several factors such as how often and how much you cook and the size of your kitchen.
Don't limit yourself to one of each kind of appliance. You can have a refrigerator in one place and a freezer in a separate area or two sets of cook tops, one on the counter next to the wall oven and one on an island. You can even have two dishwashers if size and budget require and permit—think of it as saving time in the long run.
A well-designed kitchen should be modern, beautiful and practical at the same time.
A．Right
B．Wrong
C．Not mentioned

Slowing Aging: Way to Fight Diseases in 21st Century
A group of aging experts from the United States and the United Kingdom suggest that the best strategy for preventing and fighting a multitude of diseases is to focus on slowing the biological processes of aging.
"The traditional medical approach of attacking individual diseases - cancer, diabetes, heart disease, Alzheimer's disease (早老性痴呆病) and Parkinson's disease (帕金森氏病) -will soon become less effective if we do not determine how all of these diseases either interact or share common mechanisms with aging," says S. Jay Olshansky, professor of epidemiology at the University of Illinois at Chicago School of Public Health and senior author of the commentary.
Middle-aged and older people are most often impacted by simultaneous but independent medical conditions. A cure for any of the major fatal diseases would have only a marginal impact on life expectancy (预期寿命) and the length of healthy life, Olshansky said.
The authors suggest that a new paradigm (模式) of health promotion and disease prevention could produce unprecedented social, economic and health dividends for current and future generations if the aging population is provided with extended years of healthy life.
They note that all living things, including humans, possess biochemical mechanisms that influence how quickly we age and, through dietary (饮食的) intervention or genetic alteration, it is possible to extend lifespan to postpone aging-related processes and diseases.
Further research in laboratory models is expected to provide clues to and deeper understanding of how existing interventions, such as exercise and good nutrition, may lead to lifelong well-being.
The authors also propose greatly increased funding for basic research into the
"fundamental cellular (细胞的) and physiological changes that drive aging itself."
"We believe that the potential benefits of slowing aging processes have been
underrecognized by most of the scientific community," said Olshansky. "We call on the health-research decision-makers to allocate substantial resources to support and develop practical interventions that slow aging in people."
An increase in age-related diseases and escalating health care costs make this the time for a "systematic attack on aging itself," the authors write.
Olshansky and colleagues contend that modern medicine is already heavily invested in efforts to extend life, and they argue that a fresh emphasis on aging has the potential to improve health and quality of life far more efficiently than is currently possible.
41 The experts believe the traditional approach of attacking individual diseases
A is the best strategy for fighting diseases.
B focuses on slowing aging processes.
C needs to be improved.
D has gone out of date.
