用英语介绍一下相扑，不用太长
Sumo (相扑) is a competitive full-contact sport where a wrestler attempts to force another wrestler out of a circular ring or to touch the ground with anything other than the soles of the feet. The sport originated in Japan, the only country where it is practiced professionally. It is generally considered to be a gendai budō (a modern Japanese martial art), though this definition is incorrect as the sport has a history spanning many centuries. Many ancient traditions have been preserved in sumo, and even today the sport includes many ritual elements, such as the use of salt purification, from the days when sumo was used in the Shinto （日本神道教）religion. Life as a rikishi（日语发音，大力士的意思） is highly regimented, with rules laid down by the Sumo Association. Most sumo wrestlers are required to live in communal "sumo training stables" known in Japanese as heya where all aspects of their daily lives—from meals to their manner of dress—are dictated by strict tradition.

谁能用英文来简介一下相扑这种运动？？？
相扑：一种类似摔跤的体育活动，秦汉时期叫角抵，南北朝到南宋时期叫相扑。大约在唐朝时传入日本，现为流行于日本的一种摔跤运动。相扑（すもう），古称素舞，起源于中国的汉代，由两名大力士裸露上身，互相角力。直至西元七世纪，在允恭天皇的葬礼上（西元四百五十三年），中国派遣特使到日本表演素舞致意，被认为是中国相扑首次传入日本，对日本原有的相扑造成一定影响。后来成为为日本的国技的日本的国际性的武术、格斗和体育运动。作为专业竞技项目，在日本国内称作大相扑。相扑运动员不仅要有气力，而且还要有熟练的技巧，技巧是决定比赛胜负的关键。技术大致分为推、摔、捉、拉、闪、 按、 使绊等。运动员主要用颈、肩、手、臂、胸、腹、腰、膝、腿、脚等部位, 灵活运用各种技术相互进攻。运动员（日本称为力士）按运动成绩分为10级：序之口、序二段、三段、幕下、十两、前头、小结、关胁、大关及横纲。横纲是运动员的最高级称号，也是终身荣誉称号。十两以上6级运动员的发型和腰带的质量与幕下以下4级不同。十两以上6级运动员比赛时，有入场式，穿化妆围裙。相扑裁判员（日本称为行司），按年限也分为10级。相扑裁判的等级叫做“格”，“横纲格”是裁判员的最高级称号。他们的等级用指挥扇上的缨带颜色为标志。裁判用以指挥的扇子称为“军配”，扇子指向的一方为胜者。
