Oxford and Cambridge University Boat Clubs have both taken the opportunity to travel to Spain this month to train in less testing weather conditions than those which have, quite literally, already blown around the UK in January of 2007.

Each group of athletes has been focused on training to the maximum, working on technique and molding themselves into two potential fighting units per Club for the 2007 Boat Race, sponsored by Xchanging. One set will be in the Blue Boat for each club and one set will race as reserves in Isis, for Oxford, and Goldie, for Cambridge.

In these modern times, the Head Coach for each club has a huge input on selection even though the crew is still named by the President. Just twenty years ago the balance was not quite the same.

The year 1987 will always be remembered in the history of this great Race as the year of the "mutiny" at Oxford. It is a tale which has since been retold and reworked in both a book and a movie.

This was the season for which mature Scottish student, Donald Macdonald, was elected President, having all ready won a Blue in 1986. Macdonald re-appointed Daniel Topolski (now a renowned rowing journalist and broadcaster) as Chief Coach.

Part of the 1986/87 squad at Oxford included American Chris Clark, now a coach at an American University, and four fellow US internationals.

Allegedly, a split appeared in the squad between the American quintet, all experienced and leading oarsmen, and those rowers closest to Macdonald. The Scot’s group were happy to follow Topolski’s regime whilst the others were not so sure.

Following a contentious seat racing trial in January of 1987, Topolski decided to move Clark to the bow-side of the beat. Clark disagreed. Topolski held firm. As a result Clark and his "group" within the squad decided not to ROW and sought a takeover.

The squabble was played out extensively in the UK national media and caught the public imagination. MacDonald sought support from the college captains and eventually won a vote of confidence by 28 votes to 11.

Without the Americans, the Oxford crew was immediately considered a lost cause. Cambridge were overwhelming favorites to win.

As it turned out, though, this was a Race which would prove why sport, and particularly The Boat Race, can be so fascinating.

It can be inferred that "Isis" and "Goldie" are the names of two ().

案情：2006年5月30日，北京顺昌有限责任公司、北京阳光商厦、华普建材有限责任公司、美国卡奇有限责任公司、法国水利机械有限责任公司五家公司筹划在北京成立一家股份有限责任公司。其中，北京顺昌有限责任公司和北京阳光商厦是中国公司，营业地在北京市昌平区；华普建材有限责任公司是一家泰国公司，主要营业地在曼谷，但是公司主要办事机构设在广州；美国卡奇有限责任公司，法国永利机械有限责任公司是外国公司。五个发起人公司签订发起人协议，计划设立一个总资本额为2000万元的股份有限公司，发起人认购500万元，剩下的1500万元向社会公开募集。美国卡奇有限责任公司以其商誉作价50万元作为出资，北京阳光商厦以一台机器作价50万元作为出资，华普建材有限责任公司直接用现金出资100万元，并且协议书中约定，如果公司因中方两公司的原因而最终不能成立，则中方两公司要向美国公司赔偿50万。在此期间，发起人成立了筹备委员会，向北京顺昌有限责任公司租赁了办公楼，委托北京顺昌有限责任公司购买了办公家具。北京顺昌有限责任公司购买办公家具时，因为资金周转的问题，以尚未成立的股份有限公司的名义向银行贷款50万元。发起人起草了公司章程和招股说明书，又与北京阳光证券公司承销签订代销协议，由其负责向社会承销股份。待募集相应股份后，召开创立大会。

清人姚际恒《诗经通论》曾说：“鸟语、虫鸣、草荣、木实，似《月令》（见《吕氏春秋》和《礼记》，是战国时期一部行政历法）。妇子入室，茅、绹、升屋，似风俗书。流火、寒风，似《五行志》（《汉书》中始设《五行志》，叙述金、木、水、火、土五行的关系及其对人类历史和政治生活的影响）。养老、慈幼、跻堂称觥，似庠序礼。田官、染织、狩猎、藏冰、祭、献、执功，似国家典制书。其中又有似《采桑图》、《田家乐图》、《食谱》、《谷谱》、《酒经》。一诗之中无不具备，洵（实为）天下之至文也。”试结合《七月》将周代农民一年的劳动生活按时间顺序作一简要的概括。
