你可能想不到,硬梆梆的古老的冷板凳,原来是最符合科学原理的少年专用座椅。由西方传入的沙发椅,虽然号称按照人体工程学原理设计,坐起来也感到比冷板凳舒坦许多,但它对男孩的身体发育有害无益。 You may not think that the old, hard-lined bench was originally the most suitable juvenile seat for science. The sofa chair introduced from the West, although it is said to be designed according to the principles of ergonomics, it feels much better to sit up than a cold bench, but it is harmful to the boy’s physical development.
