(作表语)2. 作定语，修饰表示处所的名词。 eg, The old man lives in a lonely mountain village.注意： alone 强调客观上的 “独自。单独一人”, 而lonely除表示“单独”外，还带有感情色彩，形容失去朋友，缺乏友爱和帮助，感到寂寞、甚至悲哀，它只能做形容词，在句中做表语，也可做前置定语，用于地点时，意为 “荒凉的，偏僻的”eg, Though the old man is alone, he doesnt feel lonely二、probably adv. 很可能，或许，大概 eg, Probably he may know the way.
