Ⅰ. lose “丢失、失去”语气较强,一般指失去后不易找回;而 miss 指人们觉察到东西已经“丢失”,含有可能找回的意思。miss 还有“想念”之意。而lose 则没有。如:
① My grandfather lost a leg in in the war. 我爷爷在战争中失去了一条腿。
② We shall all miss you when you go away. 你不在时,我们都会想念你的。
Ⅱ. 作定语和表语用时,lose 用过去分词 lost, 而mess用现在分词missing.如:
① Who has found my lost pen?谁找到了我丢失的钢笔?
② Missing book is found now. 丢失的书现在已经找到了。
