A conductor, or electrical conductor, is a substance or material that allows electricity to flow through it. In a conductor, electricalchargecarriers, usuallyelectronsor ions, move easily fromatomto atom when voltage is applied. Most metals like copper are considered good conductors, while nonmetals...
Silver is the best conductor of electricity, copper ___ it closely.A. followed B. to follow C. following D. being followed 相关知识点: 试题来源: 解析 C 考查独立主格结构。句意为“银是电的最良导体,铜紧跟其后”。本句的主语是silver.但后半句的逻辑主语是copper,所以用“逻辑主语+现在分词短语...
Silver is the best conductor of electricity，copper following it。银是电的最好道题，铜仅此于它（银）。分析：conductor 导体 bad conductor 不良导体 good conductor 良导体 overhead conductor 架空线 ; 架空导线 ; 架空电线 Central conductor 中心导体 ; 中线 ; 中间导线 Wood is a poor ...
该句的主语是silver,而分词following的逻辑主语是copper。如果不用独立主格结构,则需要两个分句,即:Silver is the best conductor of electricity; copper follows it closely. 特别要注意分句间的标点符号,该符号应该是分号或句号,不能用逗号。用逗号则表示后面需要使用独立主格结构。因此,选项D为最佳答案。
a. a poor conductor b. brittle c. malleable Copper: Copper is one of the metallic elements in the periodic table. Copper has an atomic number of 29. Copper is one of the earliest used elements in human history, with the earliest recorded uses being as far back as 8000 BC. ...
