砍倒一棵树 meaning in Chinese

down a tree

For every tree cut down , three or four new ones are planted .
每砍倒一棵树就要种上三四棵树。
But every time i wanted a piece of wood , i had to cut down a tree
每一次我需要一块木板时都不得不砍倒一棵树。
It is true , by this method i could make but one board out of a whole tree , but this i had no remedy for but patience , any more than i had for the prodigious deal of time and labour which it took me up to make a plank or board : but my time or labour was little worth , and so it was as well employ d one way as another
譬如说，为了做块木板，我先砍倒一棵树，把树横放在我面前，再用斧头把两面削平，削成一块板的模样，然后再用手斧刮光。确实，用这种方法，一棵树只能做一块木板，但这是没有办法的办法，我唯有用耐心才能完成，只有化费大量的时间和劳力才能做一块板反正我的时间和劳动力都已不值钱了，怎么用都无所谓。
