Adaptation of Living Things
Certain animals and plants develop characteristics that help them cope with their environments 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 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 needed.
B．survive even in extremely severe conditions.
C．become better adapted to the environments than others of their kind.
D．result in the evolution and production of more intelligent organisms.
第二篇
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
● Read the article below about ICT industry in China.
● For each question 23--28, choose the correct answer.
● Mark one letter (A, B or C) on your Answer Sheet.
A brief history of the ICT industries reveals four main facets of development. First, in the telecom industry, China's rapid development has had a large impact on the world telecom industry. According to Ministry of Information Industry (MII) statistics for the first half of 2003, China has the world's largest telecom subscriber base, with nearly 500 million fixed-line and mobile subscribers. Overall telecom operator service revenue grew 14 percent to US$50 billion in 2002, with over 98 percent of this revenue accounted for by the four major state-owned operators.
In the cable TV industry, China has a rather unique history. Long considered part of the state propaganda apparatus, the State Administration of Radio, Film & Television (SARFT) has traditionally been responsible for both the production as well as the transmission of content. To de-politicize the business of video transmission. SARFT has been taking steps to separate the stations (i.e., content) from the net works in recent years.
In the computer/Internet industry. China has developed rapidly. Traditionally heavily focused on hardware, to the relative neglect of software, China's computer industry has been exposed to international competition for quite some time and has developed world-class domestic suppliers, in addition, China has over 50 million Internet users and Chinese is expected to become the most widely used language on the web within this decade.
Lastly, in the electronics manufacturing industry, China has in recent years emerged as a manufacturing base, as significant portions of the supply/assembly chain (most notably in computer and telecom equipment) have moved to the PRC. China's electronics sector is ranked first among all of China's industries in terms of foreign investment attracted, export volume, industrial value added, and contribution to GDP growth.
China's overall ICT industry can be viewed as growing very rapidly in many areas. Indeed, ICT constitutes a major area of China's overall growth. In the first quarter of 2003, China's overall industrial sector's industrial value-added grew by 17.2 percent year on year, compared to 10.9 percent growth a year earlier. Nearly one-third of that growth, or 5.8 points out of 17.2 percentage points of growth, came from two sectors: telecommunications and electronics.
China's rapid development in the telecom industry has played a/an ______ role on the w0orld telecom industry.
A．minor
B．important
C．secondary
Swedish ______ production has increased steadily this year. (industry)
