People are i ndulging in an illusion whenever t hey find themselves explaining at a cocktail(雞尾酒) 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(緊密聯(lián)系在一起的工作小組), 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(恐懼) or why Susan is dissatisfied with the company after only a few months. Human interactions are complicated and never very crisp(干脆的,干凈利落的) 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(雜耍人物) 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!".
(1)A、creators
B、innovators
C、appliers
D、inventors
(2)A、technical

(3)A、trivial

C、minor
D、insignificant
(4)A、technology
B、sociology
C、physiology
D、astronomy
(5)A、technology
B、sociology
C、physiology
D、astronomy
通過內(nèi)部發(fā)起連接與外部主機建立聯(lián)系,由外部主機控制并盜取用戶信息的惡意代碼為()。

B.CA的私鑰
C.B的公鑰
D.B的私鑰
