Практикум по синхронному переводу с русского языка на английский

спринтерский отрезок — the Russian text does not say "a single" or
"one," but the image is unexpected, and adding the adjective will make
the meaning clearer to the listener.

2. 
   начавшемся процессе — In this sentence the past active participle
   needs to be rendered as a noun. "The having been begun" process will not
   work in English.
   

2. 
   идет поиск на... — this can be rendered as "There is a search
   underway/going on" rather than saying "A search is going on" which
   sounds rather awkward.
   

2. 
   не только создания... но и поддержания — when there is time this
   construction can be translated as "not only... but also;" to save time,
   "both... and" can often be used.
   

2. 
   многонациональных государств в мире достаточно много — "there
   are quite a few/quite a number of/multinational states in the world" is fine
   if the interpreter has a text. Otherwise, if the interpreter has jumped in
   and started with "Multinational states" before hearing the rest of the
   sentence, he will have to wriggle out of this syntactic bind. "Multinational
   states in today's world... are many/exist everywhere/abound" would be
   possible solutions.
   

2. 
   хочу также обратить особое внимание на такую опасную черту ре­
   гиональных конфликтов, как... — in such a construction the interpreter
   is better off rendering "такую" as "a" (dangerous feature) rather than as
   "such," which will require a "such... as" construction and may
   unnecessarily complicate the sentence.
