again'gein，英语词汇，副词，表示“又；再”，源自古英语的ongean，意为朝向，反对。歌手YUI有同名歌曲。语法用法I.again同back的意思相近，但用法不同back与动词连用时，作为副词，常指退回到前一个状态，或是从与之前相反的状态返回去，而again不可这样说。Give me my watch back.(NOT Give me my watch again.)again与动词连用时，表示“重复，再一次”。Can you play it again?注意sell back和sell again的不同，前者是卖回给同一个人，后者是再次卖，卖给不同的人。The bike you sold me is too small.Can I sell it back to you?If we buy this house and then have to move somewhere else, how easy will it be to sell it again?当动词本身指“退回，返回”的意思时，不可再用back，而可以用again加强“退回，返回”的意思。Stefan can never return to his country (again).在副词+动词+介词结构中，back和again都表示“回到上一状态”。I stood up, and then I sat (back) down (again).2.back可以用在动词和主语之间，而again则不可以Take back your money.Count the money again, please.(NOT Count again the money.)3.again and again或time and again指“反复地，频繁地”，now and again指“有时，不时”，only now and again指“难得地”；4.“as much again as”指“加百分之一百，加一倍”，而“half as much again as”指“加百分之五十，加一半”。These shoes cost me as much again as the last pair I bought.比起我上一次买的鞋，这双的价钱贵了一整倍。
