Metals are good conductors of heat and electricity because they contain a glut of free electrons. These free electrons are able to move around freely and collide with one another, propagating heat and electricity through the metal. The majority of materials that conduct heat and electricity are m...
解析 答案:being 解析:句意:几乎全部的金属都是良好的导体,其中银是最好的。句中的两部分由逗号分隔,无连词,逗号前面是含有谓语动词的句子;逗号后的部分有其主语silver,由此可推断,逗号后须要用独立主格形式。还原成句子应为“Almost all metals are good conductors, and silver is the best of all.”。
