记忆方法
记忆“ore”这个单词可以通过联想其与“more”的关系来简化。想象“ore”是“more”的一个缩写，即“more”的“o”和“r”组合在一起，形成一个矿石（ore）的意象，因为矿石是含有金属等宝贵物质的东西，就像“more”的量多一样。通过这样的联想，可以更容易地记住“ore”代表矿石的意思。

ore: see era
- ore (n.)
- 12c., a merger of Old English ora "ore, unworked metal" (related to eorþe "earth," see earth; and cognate with Low German ur "iron-containing ore," Dutch oer, Old Norse aurr "gravel"); and Old English ar "brass, copper, bronze," from Proto-Germanic *ajiz- (cognates: Old Norse eir "brass, copper," German ehern "brazen," Gothic aiz "bronze"), from PIE root *aus- (2) "gold" (see aureate). The two words were not fully assimilated till 17c.; what emerged has the form of ar but the meaning of ora.
