易错句子He is junky and needs treatment for heroin addiction.
正确表达He is a junky and needs treatment for heroin addiction.
这里 junky 是可数名词，指“吸毒成瘾者”；单数名词在句中作表语时前面要加不定冠词 a。汉语没有冠词，容易漏掉，改成 a junky 才表示“一个瘾君子”。

易错句子The police found several junkys in the abandoned house.
正确表达The police found several junkies in the abandoned house.
junky 是以辅音字母加 y 结尾的可数名词，变复数时要把 y 改为 i 再加 -es，所以复数是 junkies，不是 junkys。
junky 指人，表示吸毒成瘾者或某事物的狂热爱好者；junk 通常指无用的东西、垃圾，俚语中也可指海洛因，但不指人，二者不能互换。
指毒品成瘾者时二者近义，但 junky 更口语、常带贬义，还可指“……迷”；addict 较中性或偏临床，也可作动词，正式医疗语境中更常用。
表示“……迷”时，junky 是口语，常带戏谑或贬义，多与名词连用；enthusiast 较正式中性，通常不指吸毒者，不能用于毒品成瘾语境。
