问答题

(一)  背景资料:某机电总承包公司通过投标承接,一栋超高层办公楼的机电安装工程。总承包公司中标后,业主向总承包公司提出超出招标文件中主要合同条款的附加条件,井以此作为签订合同的前提。附加条件包括①增加净化空调系统工程:②将原计划总工期20个目改为18个月。  总承包公司与业主签订合同后,征得业主同意,将其中的几项分部一程分包给了几家具有相应资质条件的分包单位。为了防止分包单位延误工程进度,合同条款有如下内容:  “如果分包单位落后于分包合同规定的工程进度,总承包公司可以指示分包单位采取必要的措施来加快工程进度。对由于分包单位的延误所产生的误期损失,总承包公司可以从已完工作所商定的进度款中扣除部分金额作为对分包单位的罚款处理”。   消防工程完工后,总承包公司向建设单位和公安消防机构提出申请,要求对竣工工程进行消防验收,征得公安消防机构同意后,建设单位组织监理、总承包公司和分包单位共同参加现场检查和现场验收。  电梯安装中接受了当地安全监察机构的指导和监控,安装结束经自检后,由总承包公司调试,最后由建设单位将检验和调试的结果告知国务院特种设备安全监督管理部门核准的检验检测机构,要求监督检查。  问题:

     Scientists warn today that the Atlantic bluefin tuna (金枪鱼) faces disappearance unless certain action

is taken. They used electronic ways to track the movement of the powerful fish from the Gulf of Mexico

to the Mediterranean, and report today in the journal Nature that meals of sushi and sandwiches with tuna

worldwide are more dangerous than anyone has imagined.

     The bluefin tuna can live for 30 years, grow to three metres in length and weigh as much as 700kg. A

good one can fetch as much as £ 52,000 in the Tokyo fish markets."In my lifetime, we've brought this

big fish to the doorstep of death in the western Atlantic Ocean," said Barbara Block of Stanford University

in California."The electronic way of tracks provides the best scientific information we've ever had to

manage these tuna and we must, as an international community, start to act actively to make sure of the

future of this fish."

      Scientists have repeatedly said that the harvest of the seas cannot be as good as before. There are fewer

and fewer fish in around Newfoundland, North Sea and Iceland, so fishermen have pushed further offshore

in search of deep ocean fish. Tuna-in the Mediterranean and Japan-have been under increasing pressure for

years. The International Commission on the Conservation of Atlantic Tuna has tried to manage the fish since

1969.There are two populations: a western one that has dropped by 80% in the past 30 years, and a larger,

eastern population. Although catches are controlled by 3,000 tons a year in the western fishery, and 32,000

in the east, no one knew whether the limits worked.

     So Professor Block and her team placed tracks on hundreds of the fish and tracked them to depths of

more than 900 metres and on journeys of thousands of miles, measuring the movement, body and water

temperatures. "There are two ways to save the Atlantic bluefin tuna-protect them in their production grounds

and in their feeding grounds," Prof. Block said. "This will need immediate action in both the central Atlantic,

to reduce the loss of the big fish while hunting, and in the Gulf of Mexico and Mediterranean, where tuna

produce as separate populations."
