[单项选择]William "Bendigo" Thompson, heavyweight champion of England in the old bare-knuckle days was one of the dirtiest and most treacherous fighters ever to step into a prize ring. Yet he was so popular that a town, a racehorse and a liqueur were named Bendigo in his honor during his lifetime.
Bendigo Thompson was one of triplets born in Nottingham, England, on October 11, 1811. His mother was a coarse and violent woman. However, she was apparently acquainted with the Book of Daniel, for she nicknamed her three sons Shadrach, Meshach and Abednego. As a child, the latter’s name was corrupted to Bendigo.
He was raised in the slums. His mother was the terror of the neighborhood. She cursed like a fishwife and fought like an outraged army. When she lost her temper-a circumstance that occurred two or three times a day-she beat up, impartially, her children, her husband and any indignant neighbor who thrust his head in the door to protest the noise.

第三篇
Eat More, Weigh Less, Live Longer
Clever genetic detective work may have found out the reason why a near-starvation diet
prolonas the life of many animals.
Ronald Kahn at Harvard Medical School in Boston,U.S.,and his colleagues nave
been able to extend the lifespan(寿命)of mice by 18 per cent by blocking the rodent's(啮
齿动物)increase of fat in specific cells.This suggests that thinness一and not necessarily
diet一Iromotes lonq life in"calorie(热量卡)restricted" animals.
"It's very cool work",says aging researche:Cynthia Kenyon of the University ot
California, San Francisc."These mice eat all they want, lose weight and live longer.It's
like heaven."
Calorie restriction dramatically extends the lifespan of organisms as different as worms
and rodents.Whether this works in humans is still unknown,partly because few people are
willina to submit to such a strict diet.
But many researchers hope they will be able to trigger the same effect with a drug once
they understand how less food leads to a longer life.One theory is that eating less reduces
the increase of harmful things that can damage cells.But Kahn's team wondered whether
the animals simply benefit by becoming thin.
To find out, they used biology tricks to disrupt the insulin(胰岛素)receptor (受体)
gene in lab mice一but only in their fat cells."Since insulin is needed to help fat cells store
fat ,these animals were protected against becoming fat,"explains Kahn.
This slight genetic change in a single tissue had dramatic effects.By three months of
age.Kahn's modified mice had up to 70 per cent less body fat than normal control mice,
despite the fact that they ate 55 per cent more food per gram of body weight.
In addition ,their lifespan increased.The average control mouse lived 753 days,while
the thin rodents averaged a lifespan of 887 days.After three years,all the control mice had
died.but one-quarter of the modified rodents were still alive.
"That they ciet these effects by just manipulating the fat cells is controversial,"says
Leonard Guarente of the Massachusetts Institute of Technology,who studies calorie
restriction and aging.
But Guarente says Kahn has yet to prove that the same effect is responsible for
increased lifespan in calorie-restricted animals."It might be the same effect or there might
be two routes to long life,"he points out,"and that would be very interesting."
What does the last sentence in the third paragraph imply?
A.People like to lose weight,but they do not like to eat less.
B.People want to go to heaven,but they do not want to die.
C.Mice will go to heaven if they lose weight.
D.Mice enjoy losing weight.

[简答题]
某机电工程公司施工总承包了一项大型气体处理装置安装工程,气体压缩机厂房主体结构为钢结构,气体压缩机是气体处理装置的核心设备,分体到货。
钢结构厂房屋架为桁架结构,跨度24m,上弦为弧线形,下弦为水平线,下弦安装标高为18m。单片桁架吊装重量为28t,采用地面组焊后整体吊装。机电公司项目部采用2台吊车抬吊的方法,选用60t汽车吊和50t汽车吊各一台。根据现场的作业条件,60吨吊车最大吊装能力为15.7吨,50吨吊车最大吊装能力为14.8吨。项目部认为吊车的总吊装能力大于桁架总重量,满足要求,并为之编写了吊装技术方案。针对本吊装作业的特点,技术方案中针对可能发生的吊装系统失稳、吊装构件失稳的风险,进行了分析,采取了相应的预防措施。
施工过程中发生了如下事件:
事件一:监理工程师审查钢结构屋架吊装方案时,认为吊车吊装能力不能满足需要,吊装方案不可行。
事件二:监理工程师在工程前期质量检查中,发现钢结构用H型钢没有出厂合格证和材质证明,也无其他检查检验记录。建设单位现场负责人表示,材料质量由建设单位负责,并要求尽快进行施工。施工单位认为H型钢是建设单位供料,又有其对质量的承诺,因此仅进行数量清点和外观质量检查后就用于施工。
事件三:工程进行到试运行阶段,机电公司拟进行气体压缩机的单机试运行。在对试运行条件进行检查时,专业监理工程师提出:
(1)压缩机组出口主管道未试压,
(2)原料气系统未完工,不能确保向压缩机供应原料气。因此,专业监理工程师认为气体压缩机未达到试运行条件。
分别说明事件三中专业监理工程师提出的气体压缩机未达到试运行条件的问题是否正确及理由。
