A natural resource or resource is usually defined as anything obtained from the physical environment to meet human needs. Some resources are available for use directly from the environment. Examples include solar energy, fresh air, rainwater, fresh water in a river or stream, and naturally growing edible plants. Other resources, such as oil, iron, groundwater, fish, and game animals, are not directly available for our use. 【F1】
Whether these and other materials in the environment are considered to be human resources depends on a combination of human ingenuity, economics, and cultural beliefs.
【F2】
Human ingenuity enables us to develop scientific and technological methods for finding, extracting, and processing many of the earth’s natural substances and converting them to usable forms.
Groundwater found deep below the earth’s surface was not a resource until we developed the technology for drilling a well and installing pumps and other equipment to bring it to the surface. Fish and game animals are not a resource unless we have some way of catching and (in most cases) cooking them. Petroleum was a mysterious fluid until humans learned how to locate it, extract it, and refine it into gasoline, home heating oil, road tar and other products. 【F3】
Cars, television sets, tractors, and other manufactured objects’ are available only because humans developed methods for converting an array of once useless raw materials from the earth’s crust into useful forms.
Economics also determines whether something is classified as a resource or a potential resource. Some known deposits of oil, coal, copper, and other potentially useful materials are located so far beneath the earth’s surface or in such low concentrations that they would cost more to find, extract, and process than they are worth. 【F4】
In the future, however, their prices may rise due to their scarcity, or cheaper, more efficient mining and processing technologies may be developed, converting these potential resources to actual resources.
Cultural beliefs’ can also determine whether something is considered a resource. For example, protein-rich grasshoppers and other insects are considered food resources in some parts of Africa, but are viewed with disgust as sources of food in the United States and in most MDCs. In some cultures, religious beliefs prohibit the use of pork or other types of food resources. 【F5】
The perceived or actual degree of risk involved in using a resource such as nuclear power can also play a role in whether or how widely it is used.
【F4】
选项
答案
将来,这些矿产可能由于稀少而价格上涨,但也可能便宜,因为更高效的开采和加工技术将出现,从而将这些潜在资源转变为真正的资源。
解析
这是一个表示因果关系的句子,基本结构是due to为句子的原因部分,而句末部分的现在分词短语是句子的结果状语从句。or cheaper后面的more efficient也是表示原因的句子,但省略了连接词because,翻译时可采取增补法,将其意义译出来。其后的被动语态按照主动语态处理即可。在处理表示结果的状语从句时,按照汉语前因后果的习惯,放在句子末尾即可。scarcity“缺乏,不足”;process“加工,处理”。
