问题补充：
ammunition和munition在意思上有什么区别，在用法上有什么区别
答案：
【答案】 意义：
ammunition主要指弹药（projectiles to be fired from a gun）
munition（usu.pl.)指军需品的总称（military supplies considered collectively：including military weapons,ammunition and equipment)
But in the archaism ammunition also has the meaning of 军需品，later replaced by munition in this meaning.
古语中ammunition 有军需品的意思，后来因为munition用来指军需品，ammunition就主要指弹药。
用法：
munition可作n./vt./vi.
vt.供应…军需品：例句: We have been munitioned and ready for the battle.我们军需品齐备，已做好了战斗准备。
vi.从事军需品生产
adj.军需品的；生产军需品的
ammunition可作n./v
作n.时有比喻义：[比喻]炮弹(可用来为自己辩护或攻击别人的依据、证据、材料等)，进攻(或防御)手段
vt./vi.装弹药(于)；供弹药(给)
