If you are very drunk, you may be "three sheets to the wind." The phrase comes from having a ship's sails properly fastened.
如果你喝得酩酊大醉，也许你就成了“三条风中凌乱的帆绳”（three sheets to the wind）。这一习语来自于适度拉紧的船帆。
According to researchers, "sheets" refer to the ropes that fasten a sail. If one of your sheets isn't properly tied down, the ship would become difficult to control and would be "to the wind," or moving erratically.
研究者称，sheets指的是固定船帆的绳索。一旦一条绳索没有绑紧，船便会变得难以控制，随风行驶，或者飘摇不定。
