[填空题]Robot Cars to Do Battle in Desert Race

No surprise, then, that 43 teams showed up to try out for this year’s race, dubbed (被称作) the Grand Challenge. For the past week, teams ranging from garage enthusiasts to well-funded university engineers have been fine-tuning their machines at qualifying rounds here at the California Speedway in Fontana, California.

Text 2 The World Wide Web has been steadily creating a widespread surge in social capital through E-mail conversations, chat rooms, newsgroups, and e-zones.
