在加拿大的魁北克有一个南北走向的山谷,山谷没有什么特别之处,惟一能引人注意的,是它的西坡长满松、柘、女贞等树,东坡却只有雪松。这一奇异的景观许多人都不明所以,也一直没有令人满意的结论,而揭开这个谜底的,是一对夫妇。 In Quebec, Canada, there is a north-south valley. There is nothing special about the valley. The only thing that can attract people’s attention is that the west slope is full of pines, cypresses, privet trees, and the eastern slope is only cedar. Many people in this strange landscape are unaware of the fact that there has been no satisfactory conclusion. It is a couple who uncover this mystery.
