材料：The 1978 STCW Convention was the first to establish basic requirements on training, certification and watch-keeping for seafarers on an international level. Previously the standards of training, certification and watch-keeping of officers and ratings were established by individual governments, usually without reference to practices in other countries. As a result standards and procedures varied widely, even though shipping is the most international of all industries.The Convention prescribes minimum standards relating to training, certification and watch-keeping for seafarers which countries are obliged to meet or exceed.The Convention did not deal with manning levels: IMO provisions in this area are covered by regulation 13 of Chapter V of the International Convention for the Safety of Life at Sea (SOLAS), 1974, whose requirements are backed up by resolution A.890(21) Principles of safe manning, adopted by the IMO Assembly in 1999, which replaced an earlier resolution A.481(XII) adopted in 1981.The Articles of the Convention include requirements relating to issues surrounding certification and Port State Control.One especially important feature of the Convention is that it applies to ships of non-party States when visiting ports of States which are Parties to the Convention. Article X requires Parties to apply the control measures to ships of all flags to the extent necessary to ensure that no more favorable treatment is given to ships entitled to fly the flag of a State which is not a Party than is given to ships entitled to fly the flag of a State that is a Party.The difficulties which could arise for ships of States which are not Parties to the Convention is one reason why the Convention has received such wide acceptance. By December 2000, the STCW Convention had 135 Parties, representing 97.53 percent of world shipping tonnage.问题：Before the establish of the STCW78, the standards of training, certification and watch-keeping of seafarers _____.A.were established by IMOB.were established by a famous organizationC.were established by individual governments with reference to practices in other countriesD.varied widely among countriesThe regulation 13 of Chapter V of the SOLAS 1974 covered _____.A.the manning of shipsB.the standards of training certificationC.the standards of trainingD.the standards of watch-keepingOne especially important feature of the STCW Convention is _____.A.the adoption of the policy “ more favorable treatment”B.“ no more favorable treatment” to Non-parties of the conventionC.the adoption of the minimum standardsD.the adoption of the obligatory standardsOne reason why the Convention has received such wide acceptance is _____.A.that it is only the minimum standardsB.that it is the obligatory standardsC.that it is established by IMOD.difficulties could arise for ships entitled to fly the flag of a Non-Party State请帮忙给出每个问题的正确答案和分析，谢谢！

请阅读短文，完成此题。Many objects in daily use have clearly been influenced by science, but their form and function, their dimensions and appearance, were determined by technologists, artisans, designers, inventors, and engineers-use nonscientific modes of thought. This kind of thinking way is differentfrom science. Many features and qualities of the objects that a technologist thinks about cannot be reduced to unambiguous verbal descriptions; they are dealt with the mind by a visual, nonverbal process. In the development of Western technology, it has been non-verbal thinking, by and large, that has fixed the outlines and filled in the details of our material surroundings. Pyramids, cathedrals, and rockets exist not because of geometry or thermodynamics, but because they were first a picture in the minds of those who built them.The creative shaping process of a technologist's mind can be seen in nearly every artifact that exists. For example, in designing a diesel engine, a technologist might impress individual ways of nonverbal thinking on the machine by continually using an intuitive sense of rightness and fitness.What would be the shape of the combustion chamber? Where should valves be placed? Should it have a long or short piston? Such questions have a range of answers that are supplied by experience, by physical requirements, by limitations of available space, and not least by a sense of form. Some decisions such as wall thickness and pin diameter, may depend on scientific calculations, but the nonscientific component of design remains primary.Design courses, then, should be an essential element in engineering curriculum. Nonverbal thinking of a central mechanism in engineering design, involves perceptions, the stock-in-trade of the artist, not the scientist. Because perceptive processes are not assumed to entail "hard thinking", nonverbal thought is sometimes seen as a primitive stage in the development of cognitive process and inferior to verbal or mathematical thought. But it is paradoxical that when the staff began the Historic American. Engineering Record wished to have drawing made of machines and isometric views of industrial processes for its historical record of America engineering, the only college students with the requisite abilities were not engineering students, but rather students attending architectural schools.If courses in design, which in a strongly analytical engineering curriculum provide the background required for practical problem-solving, are not provided, we can expect to encounter silly but costly errors occurring in advanced engineering systems. For example, early models of high-speed railroad cars loaded with sophisticated controls were unable to operate in a snowstorm because a fan sucked snow into the electrical system. Absurd random failures that plague automatic control systems are not merely trivial aberrations: they are a reflection of the chaos that results when design is assumed to be primarily a problem in mathematics.What is the author's attitude towards design courses?查看材料A．Indifferent.B．Disapproving.C．Suspicious.D．Supporting.

共用题干第一篇Energy and Public LandsThe United States boasts substantial energy resources?Federal lands provide。good deal of US energy production,the US Department of the Interior manages federal energy leasing（租赁）,both on land and on the offshore Outer Continental Shelf. Production from these sources amounts to nearly 30 percent of total annual US energy production.In 2000,32 percent of US oil,35 percent of natural ga9,and 37 percent Of coal were produced from federal lands,representing 20,000 producing oil and gas leases and 135 producing coal leases.Federal lands are also estimated to contain approximately 68 percent of all undiscovered US oil reserves and 74 percent of undiscovered natural gas.Revenues from federal oil,gas,and coal leasing provide significant returns to US taxpayers as well as State government,In 1999,for example,$553 million in oil and gas revenues were paid to the US Treasury,and non-Indian coal leases accounted for over $304 million in revenues, of which 50 percent were paid to State governments,Public lands also play a critical role in energy delivery.Each year,federal land managers authorize rights of way for transmission lines,rail systems,pipelines,and other facilities related to energy production and use.Alternative energy production from federal lands falls behind conventional energy production,though the amount is still significant. For example , federal geothermal (地热）resources produce about 7. 5 billion kilowatt-hours（千瓦时）of electricity per year , 47 percent of all electricity generated from US geothermal energy.There are 2,960 wind turbines on public lands in California alone,producing electricity for about 300 ,000 people. Federal hydropower（水电）facilities produce about 17 percent of all hydropower produced in the United States.Because of the growing US thirst for energy and increasing public unease with dependence on foreign oil sources,pressure on public lands to meet US energy demnand is becoming more intense.Public lands areavailable for energy development oniy after they have been evaivated through the land use planning process. If development of energy resources conflicts with management or use of other resources,development restric- lions or impact moderation measures may be enforced,or mineral production may he banned altogether.What ig the main idea of this passage?A:Public lands play an important role in energy production.B:Public lands are one of the main sources of revenues.C:Public lands should be developed to ease energy shortage. D:Public lands store huge energy resources for further development.
