People are indulging in an illusion whenever they find themselves explaining at a cocktail (鸡尾酒) party, say, that they are "in 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 business. The rest of us are (8) of their work. We use computers and other new technology 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 mostly in the human communication business. Our successes stem from good human interactions by all participants in the effort, and our failures stem from poor human interactions.
The main reason we tend to focus on the (9) rather than the human side of the work is not because it’s more (10) , but because it’s easier to do. Getting the new disk drive installed is positively trivial compared to 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 (11) rather than the (12) , you’re like the vaudeville character (杂耍人物) who loses his keys on a dark street and looks for them on the adjacent street because, as he explains, "The light is better there!".

A．trivial
B．crucial
C．minor
D．insignificant

Helen Keller was born in America in June, 1880. Everything was all right when she was born. But when she was 19 months old, an attack of fever left her blind and deaf for the rest of her life. She was so young when she became blind that as she grew older she did not remember being able to see; and she became deaf before she had any idea of the importance of human speech. She lived in darkness and silence.

As she grew older, she, too, wanted to express her ideas and feelings. But she realized she was cut off from others. Her parents were greatly worried. How could anyone make touch with Helen’s mind and intelligence in darkness and silence without speech? Helen was nearly seven before a teacher was found. Her name was Miss Sullivan.

Miss Sullivan had a lot of difficulties in teaching Helen Keller. As the child could neither see nor hear, she had to use manual alphabet. But Helen’s energy and intelligence and strong spirit as well as Miss Sullivan’s skill and patience, overcame all the difficulties. As Helen grew up, she became an able student, passed examination and finally took a university degree in English literature. She then devoted all herself to helping the blind and the deaf. Her personal success, together with the work she had done for others, made her one of the greatest women in modern times. She wrote many books and “The Story of My Life”is a wonderful one.
