【单选题】Nerve signals may travel through nerve or muscle fibers at speeds as high as two hundred miles per hour.





网考网参考答案:A
网考网解析:

[解析] 本句意思是“神经信号在神经及肌肉纤维里以每小时200公里的速度传递”。speed“速度”;velocity“速度,快速”。例如:The car was moving at such a velocity!那辆汽车的速度简直太快了!impulse“冲动”,如:He bought the house on an impulse.他一时冲动买下了这所房子。ratio“比率”,如:The ratio of schoolboys to schoolgirls is 2 to 1.男学生和女学生的比例是2比1。atrocities“暴行”,如:People were annoyed by his atrocity.他的暴行激怒了人们。只有选项A与speed含义相近。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
