A。此题考查演绎推理。因为金属导电,铜是金属,所以铜导电,A 选项 conducts 正确,B 选项 doesn't conduct 意思是不导电,不符合推理;C 选项 conduct 形式错误,主语 copper 是第三人称单数,要用 conducts;D 选项 don't conduct 形式错误且意思不符合推理。反馈...
How Granular Metals Conduct Electricitydoi:10.1038/physci235141a0NoneNature Physical Science
Why do metals conduct heat so well?The electrons in metal are delocalised electrons and are free moving electrons so when they gain energy (heat) they vibrate more quickly and can move around, this means that they can pass on the energy more quickly.Which metals conduct the best?
