[单项选择]Elaine, Justin’s mom, had set down the house rules with self-confident assurance. Only the most obtuse person would have failed to understand: no tattoos, no body piercings and no co-ed sleepovers while living in the house of Elaine Tucker Brown. Still, the day Justin turned 18, he lied to his mother about where he was going and headed straight to the tattoo parlor, as if impervious to his mother’s wrath. He got a light blue heart, the size of an orange permanently etched on his arm. Above this work of art was the word "Blessed". No, Justin was not stupid, but he was obstinate. Elaine saw this as an act of sheer defiance. She was incensed, her anger exacerbated by the fact that Justin had breezed into the house, found her in the kitchen, taken off his shirt with a smile and said, "Got it!" "No, Justin. Let me tell what you’ve got, " Elaine said angrily. "You’ve got five minutes to go upstairs and pack a bag. I am taking you to Pop-Pop’s. " The ride to Pop-Pop’s house was chilly, to say

[简答题]

The Organization for Economic Co-operation and Development (OECD) conservatively estimates that, by 2005, worldwide electronic, computer-dependent commerce will grow from its current $30 billion annually to approximately $1 trillion every year . 61) Growth in electronic commerce is not a straight line trend—it comes slowly at first, then accelerates rapidly. For example, an innovation at one Internet site may create a base that leads to the development of many other sites. The OECD timber estimates that, of this commerce,80 percent will be business-to-business, though the retail share will clearly be worth capturing — 20 percent of $1 trillion is no small figure.
