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.

Macdonald had to seek support from the college captains because ______.

A．the public imagined he was not competent to command his crew

B．the Chief Coach Topolski lost the experienced American oarsmen

C．the Oxford crew was unlikely to win the Race without the Americans

D．the Americans would leave the squad unless they were to lead it

【背景资料】

某新建工业厂区，地处大山脚下，总建筑面积16000m²，其中包含一幢6层办公楼工程，摩擦型预应力管桩，钢筋混凝土框架结构。

在施工过程中，发生了下列事件：

事件1：在预应力管桩锤击沉桩施工过程中，某一根管桩在桩端标高接近设计标高时难以下沉；此时，贯入度已达到设计要求，施工单位认为该桩承载力已经能够满足设计要求，提出终止沉桩。经组织勘察、设计、施工等各方参建人员和专家会商后同意终止沉桩，监理工程师签字认可。

事件2：连续几天的大雨引发山体滑坡，导致材料库房垮塌，造成1人当场死亡，7人重伤。施工单位负责人接到事故报告后，立即组织相关人员召开紧急会议，要求迅速查明事故原因和责任，严格按照“四不放过”原则处理；4h后向相关部门递交了1人死亡的事故报告，事故发生后第7天和第32天分别有1人在医院抢救无效死亡，其余5人康复出院。

事件3：办公楼一楼大厅支模高度为9m，施工单位编制了模架施工专项方案并经审批后，及时进行专项方案专家论证。论证会由总监理工程师组织，在行业协会专家库中抽出5名专家，其中1名专家是该工程设计单位的总工程师，建设单位没有参加论证会。

事件4：监理工程师对现场安全文明施工进行检查时，发现只有公司级、分公司级、项目级三级安全教育记录，开工前的安全技术交底记录中交底人为专职安全员。监理工程师要求整改。

事件2中，施工单位负责人报告事故的做法是否正确？应该补报死亡人数几人？事故处理的“四不放过”原则是什么？
