The discovery that language can be a barrier to communication is quickly made by all who travel, study, govern or sell. Whether the activity is tourism, research, government, policing, business or data dissemination, the lack of a common language can severely impede progress or can halt it altogether.

　　Although communication problems of this kind must happen thousands of times each day, very few become public knowledge. Publicity comes only when a failure to communicate has major consequences, such as strikes, lost orders, legal problems or fatal accidents--even, at times, war. One reported instance of communication failure took place in 1970, when several Americans ate a species of poisonous mushroom. No remedy was known, and two of the people died within days. A radio report of the case was heard by a chemist who knew of a treatment that had been successfully used in 1959 and published in 1963. Why had the American doctors not heard of it seven years later? Presumably because the report of the treatment had been published only in journals written in European languages other than English.

　　Several comparable cases have been reported. But isolated examples do not give an impression of the size of the problem--something that can come only from studies of the use or avoidance of foreign-language materials and contacts in different communicative situations. In the English- speaking scientific world, for example, surveys of books and documents consulted in libraries and other information agencies have shown that very little foreign-language material is ever consulted. Library requests in the field of science and technology showed that only 13 percent were for foreign language periodicals.

　　The language barrier presents itself in stark form to firms who wish to market their products in other countries. British industry, in particular, has in recent decades often been criticized for its linguistic insularity---for its assumption that foreign buyers will be happy to communicate in English, and that awareness of other languages is not therefore s priority. In the 1960s, over two- thirds of British firms dealing with non-English-speaking customers were using English for outgoing correspondence; many had their sales literature only in English; and as many as 40 percent employed no-one able to communicate in the customer's languages. A similar problem was identified in other English-speaking countries, notably the USA, Australia and New Zealand. And non-English speaking countries were by no means exempt--although the widespread use of English as an alternative language made them less open to the charge of insularity.

　　The criticism and publicity given to this problem since the 1960s seems to have greatly improved the situation. Industrial training schemes have promoted an increase in linguistic and cultural awareness. Many firms now have their own translation services. Some firms run part-time language courses in the languages of the countries with which they are most involved; some produce their own technical glossaries, to ensure consistency when material is being translated. It is now much more readily appreciated that marketing efforts can be delayed, damaged or disrupted by a failure to take account of the linguistic needs of the customer.

　　51. What ways have been used by the British companies to solve the problem of language barrier since the 1960s?

　　47. major consequences

　　48. They probably only read reports written in English.

　　49. surveys/ studies

　　50. sales literature outgoing correspondence

　　51. Industrial training schemes, translation services, part-time language courses and technical glossaries.

　　47.第二段第二句“Publicity comes only when a failure to communicate has major consequences， such as strikes，lost orders，legal problems or fatal accidents—even，at times，war.”中的“Publicity”就是題目中的“come to the attention of the public”，由此可見，當(dāng)語言障礙導(dǎo)致“重大后果(major consequences)”，如罷工等等社會問題或者致命的事故時，才會引起關(guān)注。因此，答案為“major consequences”。

　　48.毒蘑菇事件是作者在第二段關(guān)于語言問題導(dǎo)致致命事故所舉的例子。第二段最后一句作者講道“Presumably because the report of the treatment had been published only in journals written in European languages other than English.”，由此我們可以推斷美國醫(yī)生大概很少讀用英語以外的語言所寫的報道或論著。故答案為“They probably only read reports written in English”。

　　49.第三段第二句“But isolated examples do not give an impression of the size of the problem- something that can come only from studies of the use or avoidance of foreign-language materials and contacts in different communicative situations.”中的“size of the problem”就是指問題的嚴(yán)重程度，即題目中的“extent of the language barrier”�？梢姟把芯俊蓖庹Z材料的使用情況可以幫助了解語言障礙問題的程度。由此，答案可以是“studies”。第三段第三句“In the English-speaking scientific world，for example，surveys of books and documents consulted in libraries and other information agencies have shown that very little foreign-language material is ever cnsulted.”指出調(diào)查信息機構(gòu)中書和文件的查閱情況可以知道對外語材料的查閱很少�？梢姟罢{(diào)查”這些材料的查閱情況可以獲得證據(jù)。由此，答案也可以是“surveys”。

　　50.由第四段第三句“In the 1960s，over two-thirds of British firms dealing with non-English- speaking customers were using English for out going correspondence;many had their sales literature only in English”可見他們用英語來寫往來函件和產(chǎn)品說明、銷售宣傳這樣的一些材料。由于題目只要求寫出一個例子，所以答案可以是“sales literature”或者“outgoing correspondence”。

　　51.文章最后一段提到了20世紀(jì)60年代以來英國的各家公司用于解決語言障礙問題的四種方法：“Industrial training schemes have promoted an increase in linguistic and cultural awareness.Many firms now have their own translation services.Some firms run part-time language courses in the languages of the countries with which they are most involved;some produce their own technical glossaries，to ensure consistency when material is being translated.”，因此，答案為“Industrial training schemes，translation services，part-time language courses and technical glossaries.”。
