A Desert Between Paul and Clara
Paul had long promised to marry Clara. But at thirty-three he met and married Alice. Clara was driven mad.
Paul was taken to court. The judge ordered him to pay Clara $600 because of the broken promise. Paul had to borrow the money from a moneylender. He agreed to pay back $5 a month--for twenty years. His wages at the time were $16 a month.
Paul and Alice were poor but not unhappy. They had little enough food, certainly, even before the children began to arrive. Each month Paul paid $5 to the moneylender. He worked hard, never taking a holiday, in time, there were seven mouths to feed.
Illness was always with them. It grew serious when the oldest child was eight. The years of hunger weakened the family, because each month Paul paid $5. The details of the sickness were ugly, but the result was this: after twelve years of family life, Paul was alone in the world.

[单项选择]
The first big-name hackers include Steve Wozniak, Bill Gates and Linus Torvalds, all now highly recognizable names behind many of the computer technologies used today. These early hackers had a love of technology and a compelling need to know how it all worked, and their goal was to push programs beyond what they were designed to do. Back then, the word "hacker" didn’t have the negative connotation it has today. The original hacker ethic, rooted out of simple curiosity and a need to be challenged, appears to be dead.
The objectives of early hackers are a far cry from the goals of today’s hacker. The motivation of the new breed of hackers appears not to be curiosity, or a hunger for knowledge, as it used to be. Instead, most of today’s hackers are driven by greed, power, revenge, or some other malicious intent, treating hacking as a game or sport, employing the tools that are readily available via the Internet.
