请教语法01－05－34

34.The carbon-are lamp, a very bright electric lamp used for spotlights, consists of two carbon  electrodes with a high-current are passing between it.

答案是it ->them

但我认为with 也是错的，它是prep，后面怎么可能出现are passing 呢？是否也应该把with 改为when/while?

确实有问题，但是这样改也不对，a current的谓语应是单数，所以本来are就不该存在

consists of two carbon  electrodes with a high-current passing between them

确实存在这个问题,with后面怎么能跟句子呢?
