第12题：
问答题Passage 1 Neither the Americans nor the Russians have the resources to continue human space flight on their own; both sides know they need each other. (1) It’s much easier and cheaper to get used to each other and to blend differing operating styles, languages, and systems on the aged Mir (a Russian word for “peace”) than trying to do that while jointly building a new space station. NASA, in fact, calls its program of shuttle lights to Mir Phase 1 of the International Space Station (ISS). Phase 2 marks the beginning of actual construction. The procedures used to dock the shuttle to Mir, for example, also will be used as a lifeboat for the Island Progress freighters, like the one that crashed into Mir in June, will haul cargo to the ISS. (2) One unintended benefit of Mir’s technical troubles is that they have actually forced the two nations to work much more closely together than they had planned. Except for a brief period in the 1970s with Skylab, NASA has never operated a space station; the Russians have been running them for years. Astronauts have long been trained intensively to perform specific tasks on shuttle flights lasting 18 days or less. (3) Russian astronauts, however, learn more general skills, since they spend many months in orbit and no one can forecast all the problems they might encounter. As a result of shuttle-Mir experience, NASA is revising astronaut training to include more of the general skills they will need on the ISS. NASA decided to send astronauts to Mir based on its long record of safe operation. But this year, crews aboard Mir have faced two of the most serious emergencies in the history of human space flight. (4) In February, an oxygen generator caught fire, shooting out 4-foot-long jets of flame like; fire extinguishers were bolted in place, delaying reaction to the fire. In June, a Progress Freighter collided with the Specter module, puncturing it. Specter had to be sealed off to prevent all the air from leaking from the spacecraft. (5) The ancient computer that controls Mir has failed many times, causing most other systems, including the one that keeps the station’s solar panels pointing at the sun, to shut down. One failure in August occurred while a Progress was docking. Last week, the computer crashed again, the carbon dioxide removal system shut down, and a mysterious brown fluid — probably rocket fuel — appeared to leak from the station.正确答案： 1. 双方在已经建成多年的和平号上相互适应,并将不同的操作风格、语言和系统结合起来,要比联手建起一个新的空间站后再来这样容易得多,也省钱得多。
(本题一是考查比较结构的理解和翻译,二是考查it作形式主语、不定式作真正主语这种句型以及从句的理解和翻译。结构上,本句的主干是It’s much easier and cheaper…than…,第一个省略号处的两个并列的不定式是真正主语;第二个省略号处引出的是比较部分,且其中含有一个由while引导的时间状语从句。在词汇上,each other指的是美俄“双方”。aged则指和平号空间站已经建成多年。cheap意为“便宜”,但在此宜译为“省钱”。此外,在翻译时,考生还要注意译后句子成分的完整性。)
2. 和平号的技术故障带来了一个意想不到的好处,那就是这些故障其实已经迫使美俄两国在合作的密切程度上超过了各自的预期。
(本题考查的是表语从句和比较句式的理解和翻译。在结构上,that引导的是一个表语从句,说明benefit的内容;但其中又含有一个省略了引导词的从句作than的宾语。建议将表语和同位语从句翻译成单独的句子,用“那就是,即,也就是说”等词汇进行衔接,使其更符合中文表达习惯。在词汇上,unintended意为“非故意的,无意识的”,在此宜译为“意想不到的,意料之外的”。另外,还要注意表语从句使用的是完成时态,应在翻译中体现出来。)
3. 然而,俄罗斯宇航员能学到更多的综合性技能,因为他们会在轨飞行多月,且没人能够预测他们可能遇到的所有问题。
(本题主要考查从句的理解和翻译。在结构上,句子主干是Russian astronauts learn more general skills,其后的since引导原因状语从句,而这个从句中含有两个由and连接的并列句,且后一个并列句中还含有一个省略了连接词的定语从句(they might encounter)修饰problems。在词汇上,general skills意为“综合性知识,普通的技能”。in orbit指的是待在沿轨道飞行的空间站里。)
4. 在二月份,一台氧气发生器失火,喷出了几乎长达四英尺的火焰;而灭火器却因为被拴在固定的位置上,耽误了救火。
(本题主要考查非谓语结构的理解和翻译。在结构上,主干是两个并列句。在两个并列句中各有一个动词的ing形式的非谓语结构,作状语。对于这种结构,一般应补足相应成分,翻译成完整的句子。在词汇上,bolted in place意为“被拴(或固定)在所处的位置上”。delaying reaction to the fire指的是耽搁了人们对火灾采取的相应行动,应意译,而不能直译为“反应”。)
5. 控制和平号的那台老爷电脑已经发生了多次故障,造成其他大多数系统都关闭了,其中就包括让空间站的太阳能电池板指向太阳的那个控制系统。
(本题主要考查非谓语结构和从句的理解和翻译。在结构上,主干是The ancient computer has failed many times,其主语部分含有一个由that引导的定语从句,而causing most other systems…则是一个非谓语结构,作结果状语,其中由including引出的部分是一个介词结构,且其中含有一个由that引导的定语从句修饰the one。由于介词结构较长,建议将其翻译为单独的句子。在词汇上,ancient在此带有幽默意味,强调这台电脑的过时。shut down为固定搭配,意为“关闭,停止运转”。)解析： 暂无解析 -

第15题：
Due to the large amount of heat picked up by the air in boiler and engine rooms, it would be impracticable to maintain ambient conditions within the comfort zone by air conditioning or any other means. The normal practice is to provide copious mechanical ventilation; in boiler rooms, the quantity is equated to the combustion requirements, while in a motor ship engine room the supply may be 25-50% in excess of the requirements of the engines.
The axial flow fan is particularly suited to handle these large air volumes at the moderate pressures required, while of course the “straight-through” flow feature places it at an advantage over the centrifugal fan.
The increasing adoption of automation, with the provision of a separate control room makes less significant the fact that comfort conditions cannot be maintained in the engine room all the time. Which of the following devices should be taken to maintain ambient conditions of the boiler and machinery space?
A.air compressor
B.air cooler
C.air-conditioning plant
D.mechanical ventilation plant
正确答案：D

D:effort答案：D解析：本句意思是：全国的人都尽最大的努力帮助遭受水灾的人们。句中endeavor意为“努力”，如：Thereupon , we knew , our endeavor was valuable.于是，我有1知道，我们的努力是有价值的。四个选项中debut意为“首次露面”，如：He will make his debut for the first team this week.本周他将在第一支出场的队伍中首次亮相。experiment意为“实验”。miracle 意为“奇迹”，如：The compact disc is a miracle of modern technology.激光唱片是当代技术的奇迹。effort意为“尝试，努力”，如：He made a concentrated effort to finish the work on time.他全力以赴以按时完成这项工作。只有选项D同句中画线词语含义接近。 -
