When a big ship is in very rough(不平坦的) sea, it has to be able to bend(弯) a little, otherwise it may break in two. If one end of the ship is on the top of one huge wave, and the other end is on the top of another, with the middle of the ship hanging in between; or if one huge wave comes up under the middle of the ship, leaving the two ends hanging, the ship's own weight will break its back if it is quite stiff(硬的).

　　To make a big ship elastic(有弹性的) enough to avoid (避开) this danger, it has joints where the sections of the ship come together above the water-line, and these joints (连接处) open and shut slightly as the waves lift one section(部分) of the ship or another. This is enough to save the ship from breaking into pieces.

　　One day a sailor was walking along a passage-way in a big ship during a storm when he was surprised to see a boy sitting comfortably in a chair at the end of the passage-way, which was opposite one of the ship's joints. The boy had a bag of nuts beside him, and every time the ship was lifted by a wave and the joint opened, he put a nut in it. As the ship came down again, the joint closed and cracked(压碎) the nut, gently but firmly. The boy then took it out and put the next one in as the joint opened again.
