试题1

People  are  i ndulging  in  an  illusion  whenever  t hey  find  themselves  explaining  at  a cocktail(鸡尾酒)  party,  say,  that  they  are  "i n  computers,"  or  "in  telecommunications,"  or  "in electronic  funds  transfer".  The  implication  is  that  they  are  part  of  the  high-tech  world.  Just between  us,  they usually  aren't.  The researchers  who made fundamental breakthroughs in  those areas are in a high-tech busi ness. The rest of us are  （1）  of their work. We use computers and other new t echnology  components to  develop  our  products  or  to  organize our  affairs.  Because we  go about  this work  in teams and projects and other tightly knit  working  groups(紧密联系在一起的工作小组),  we  are  mostl y  in  the  human  communication  business.  Our  successes  stem
from  good human  int eractions  by  all  participants in  the effort,  and our  failures  stem  from  poor human interactions.
The main reason we tend to focus on t he  （2）  rather t han the human side of the work is
not because it's more  （3）  , but because it's easier to do. Getting the new disk drive installed is positively trivial compared t o figuring out why Horace is in a blue funk(恐惧) or why Susan is dissatisfied with the company after only a few months. Human  interactions are complicated and never  very  crisp(干脆的,干净利落的) and  clean in  their effects, but they  matter  more  than any other aspect of the work.
If you find yourself concentrating on the  （4）  rather than the  （5）, you're like t he
vaudeville character(杂耍人物)  who loses  his  keys  on  a  dark  street and  looks  for  them  on t he adjacent street because, as he explains, "The light is better there!".
