而且我们英语书上写的While Linda was buying a newspaper at the train station,the dog got out of his box and ran away.英语书上写buy跟在while后面算延续性动词,可我认为buy应该是短暂性动词.到底哪个对?

你好:
延续性是相对于"完成时态" 而言的, buy 不能直接用于完成时态中, 因为buy 只能是一个瞬间完成的短暂性动作, 它不能用于完成时态中, 对于要表达, "已经购买某物多长时间" 可以用keep 来代替, 如: He has kept the book for two month .(而不说成: He has bought the book for two month)
对于While 后面的buy , 由于是表示"做某件事的同时, 另一件事发生了" 这里while 后面用的是现在分词形式, 可以理解为"延续性动词" (但是一般不这样来界定延续非延续)

所以 buy 严格意义上来说, 是非延续性动词.
