How Do Plants 'Drink' Water from the Ground?
植物怎样从地下‘喝’水？
精读先不看文字，完整听一遍。
-
Plants absorb water through tiny root hairs just behind growing roots.植物通过生长点后方的细小根毛吸收水分。
-
Water moves upward inside thin tubes called xylem vessels.水分在称为木质部导管的细小管道中向上运输。
-
This movement is driven partly by evaporation from leaf surfaces.这一运动部分由叶片表面的水分蒸发驱动。
-
Root pressure and capillary action also help push water upward.根压和毛细作用也助力水分向上输送。
-
Plants lose huge amounts of water daily through tiny leaf pores called stomata.植物每天通过叶片上微小的气孔大量散失水分。
-
Minerals dissolved in water travel with it to leaves and stems.溶解在水中的矿物质随之运送到叶片和茎部。
-
Without this system, tall trees could not get water to their top leaves.若无此系统，高大树木无法将水分输送至顶端叶片。
-
It’s a quiet, constant flow powered by sunlight and air.这是一种由阳光和空气驱动的安静而持续的流动。

课程开发中，敬请期待。成人和孩子都可以先自学听读、精读。
这边的讲解音轨还在做。想先跟着老师走完固定 30 课，可以去陈老师带读社（和自学通行不是同一份会员）。
