tree taper造句

However-if the tree tapers strongly then it's possible that the bottom 6 meters will be heavier than the topmost 12 meters-and then the heavier bit might dip into the water-but at least you could loop a rope over the top of the tree and with a modest amount of weight-pull it down so it's horizontal.
It's difficult to find tree taper in a sentence. 用tree taper造句挺难的
