The term "off the grid" refers to living in a self-sufficient manner without reliance on one or more public utilities. The popularity of off-grid living is higher now than ever before. According to a recent estimate, there are around 1.7 billion people living off-grid worldwide, and this number is rising each year. Off-the-grid homes do not rely on municipal water supply, natural gas, electrical power grid, or similar utility services. A true "off the grid" house is able to operate independently of all traditional public services. Electrical power can be generated on-site with renewable sources such as solar, wind or geothermal (地热的)energy; with a generator and adequate fuel reserves; or simply done without. Such an electricity system is called a stand-alone power system. On-site water sources can include a well, stream, or lake. Depending on the water source, this may include pumps and/or filtration. Rainwater can also be harvested. Any roof space can be source of water supply. By simply installing a water storage tank, whether that be above or below ground, a large amount of rainwater that would otherwise go to waste can quickly be collected and stored for suitable uses later. In a book entitled How to Live Off-grid, the author lists seven reasons for going off-grid. The top two are saving money, and reducing the carbon footprint. Another is survivalism, which means preparing for emergencies such as disruptions in social order. Others include preparing for the collapse of the oil economy and bringing life back to the countryside. Going off-grid can be done to lower the environmental impact of living, as the typically limited amount of on-site renewable energy available is an incentive to reduce its use. But if energy usage is not reduced, going off-grid actually has a larger environmental impact than using the grid, due to the lower efficiencies of the components. It is often done to residential buildings which are only occasionally occupied, such as vacation cabins, to avoid high initial costs of traditional utility connections. Other people choose to live in houses where the cost of outside utilities is prohibitive, or such a distance away as to be impractical. In situations where grid parity (电网平价)has been reached, it usually becomes cheaper to generate one's own electricity rather than purchasing it from the grid. This depends on equipment costs, the availability of renewable energy sources (such as wind and the sun)and the cost of a grid connection. For example, in certain remote areas a grid connection would be prohibitively expensive, resulting in grid parity being reached immediately. What is the author's attitude toward "off the grid" life? A Positive. B Neutral. C Indifferent. D Negative.

题目解答
答案
解析
考查要点：本题主要考查学生对作者态度的判断能力，需要通过文章中的客观描述与隐含观点进行推理。
解题核心思路：
- 定位关键语句：寻找文章中直接或间接反映作者观点的句子，如评价性词汇、举例或对比。
- 分析客观性：判断文章是否仅陈述事实（如定义、数据、技术细节），还是包含主观评价（如“值得推荐”“不可取”等）。
- 排除干扰项：注意作者是否对正反两面均有所提及，避免因局部信息误判态度。
破题关键点：
- 文章整体以客观介绍为主，未使用明显的情感色彩词汇（如“great”“terrible”）。
- 作者既提到离网生活的优势（如环保、经济性），也指出其局限性（如效率问题），呈现平衡视角。
步骤1：梳理文章结构与内容
文章分为五段：
- 定义与现状：解释“off the grid”的概念，说明其普及程度。
- 技术实现：详细描述能源、水源等基础设施的解决方案。
- 选择原因：列举经济、生存、环保等动机。
- 环保与经济性：分析离网对环境的影响及适用场景。
- 电网平价：讨论经济可行性，强调因地制宜。
步骤2：寻找态度线索
- 正面描述：
- “can be done to lower the environmental impact”（第四段）
- “cheaper to generate one's own electricity”（第五段）
- 反面提示：
- “if energy usage is not reduced, going off-grid actually has a larger environmental impact”（第四段）
- “cost of outside utilities is prohibitive”（第四段）
步骤3：综合判断
作者未明确表达支持或反对，而是通过数据、技术细节和正反两面的分析，让读者自行判断。例如：
- 第三段引用书籍中的原因，但未表明是否认同。
- 第四段指出离网的环保性依赖于节能，暗示需理性看待。
- 第五段强调经济性需结合具体条件，避免绝对化。
