词性不同,finally是副词,修饰动词。
last不但可以做副词,也可以做形容词、动词和名词,举例We finally managed to talk them round to our way of thinking.我们最后总算说服他们接受我们的想法。This is our last bottle of water.这是我们最后的一瓶水了。
finally:是副词,例如,He got to school finally.
而last形容词,最后的,上一个的,例如,last name,last year…
last还可以作动词持续的意思。例如,The rain lasted four hours.
