题干材料：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.问题：Which of the following devices should be taken to maintain ambient conditions of the boiler and machinery space?A.air compressorB.air coolerC.air-conditioning plantD.mechanical ventilation plantIn a motor vessel, the air quantity which the engine room need is_______ of the requirements of the engines.A.less than 25-50%B.more than 125-150%C.more than 25-50%D.less than 125-150%According to this passage, which of the following statements is true?A.In boiler and machinery spaces, there is the air conditioningB.In the boiler rooms the requirement of air volume should meet 25-50% of combustion requirementC.To maintain the comfort zone in the separate control room the air conditioning plant should be fittedD.The comfort conditions can be maintained in the engine room all the timeAt the middle pressure and large air quantity,_________ is more suitable.A.an axial flow fanB.a radial flow blowerC.a centrifugal fanD.an auxiliary blower请帮忙给出每个问题的正确答案和分析，谢谢！

As with spoken language, writtenlanguage is always used for a purpose. People read a text 11 they think that it will enable them tofind answers to questions that they are interested in answering. People writeto express an 12 or to give information to particularreaders. There are, of course, many different purposes for reading and writingand different purposes will 13 different reading and writing styles.
In general, written language isstructurally more "correct" than spoken language. It has clear wordand sentence 14 and its information is more denselypacked. More is said in 15 words. However, written language alsocontains both structural and contextual redundancy and this can help readers to 16 the text.
Written language is often structurally more 17 than spoken language. This is becausewhen people write they have 18 to think about what they want to writeand are able to 19 to what they have written and revise itas often as they wish. This greater, structural complexity is one factor that maymake a text 20 to understand.
When people read in their first language,they do not usually read every word in the text. Readers 21 their eyes across and down the textstopping at groups of words (fixations) to check for meaning. The speed withwhich people read 22 their purpose for reading and on how 23 a range of possible meanings their brainhas to choose from at every fixation. 24 readers use the structuraland contextual redundancy of the language, their 25 of what they have already read and thegeneral knowledge they already have to 26 what will come next, and so 27 the number of possible choices that thebrain has to consider at any fixation.
Both writers, when choosing how to expresstheir 28 meaning for the audience that they have inmind, 29 readers, when interpreting writers′meaning, rely not only on their linguistic knowledge, but 30 their general knowledge of the context inwhich they are reading and writing. Such knowledge, whether specificallylinguistic or contextual, is stored in the long-text memory.
A.sweet
B.easier
C.sensitive
