A proton is an elementary particle of matter that (拥有) a positive charge.相关知识点: 试题来源: 解析 possesses 本题考查动词解题步骤:1. 分析句意:质子是带正电荷的物质的基本粒子。2. 确定答案。根据中文提示"拥有",确定单词为possess。句意为客观真理,因此应用三单形式,故本空填possesses。
The meaning of PROTON is an elementary particle that is identical with the nucleus of the hydrogen atom, that along with the neutron is a constituent of all other atomic nuclei, that carries a positive charge numerically equal to the charge of an electro
pro表示专业的，ton表示吨位的意思，专业的吨位显然就是很大的质量，也就是质子，所以proton表示的是质子的意思，例如，A proton is an elementary particle of matter，that possesses a positive charge，质子是带正电荷的物质的基本粒子，proton质子这个单词你记住了吗？
