Dr. Hall’s interest in man’s use of space developed in the early nineteen fifties when he was Director of the Point Four training program at the Foreign Service Institute. In talking with Americans who had lived overseas, he found that many of them had been highly uncomfortable because of culture differences. Such discomfort is usually referred to as culture shock.
The problem is that, relatively speaking, Americans live in a noncontact culture. Partly, this is a product of our puritan heritage (清教徒文化遗产). Dr. Hall points out that we spend years teaching our children not to crowd in and lean on us. And in situations where we ourselves are forced to stand close to another person on crowded subways, for example, we turn our eyes away, and if actual body contact is involved, tense the muscles on the contact side. Most of us feel very strongly that this is the only proper way to behave.
When the Arabs talk to you, they ______.
A．try to be as close to you as possible
B．keep a certain space from you
C．hold you tightly
D．do not allow you to feel their breath
This year's crop of 23 entrants were offered an even greater incentive—a $2m prize for the winner. That, plus the intervening 18 months, seems to have done the trick. This time, five vehicles finished the 211 km course. The winner, a modified Volkswagen Touareg dubbed Stanley by its makers, a team from Stanford University, did it in a mere six hours and 54 minutes.
Stanley was, of course, specially hardened by its designers for the rough terrain of the Nevada desert. The clever bit, however, was the vehicle's brain. This was designed and built by the Stanford Artificial Intelligence Laboratory (SAIL).
Stanley's brain consists of six top-of-the-range Pentium chips wired collaboratively together. It is programmed with special software that is able to learn from its mistakes. This software mastered the tricks of collision-avoidance in a series of desert test runs conducted before the race started.
Like all brains, Stanley's has a range of sensory inputs to process. A global positioning system (GPS) receiver tells it where on the Earth's surface it is. Television cameras, radar and four laser based distance monitors tell it what its surroundings are like. By comparing its GPS location with its pre-programmed destination (announced only a few hours before the race began), it knew which way it wanted to go. And, by studying its surroundings, it could work out what looked like the safest route that was also in approximately the right direction.
Although Stanley carried off the laurels, the other four finishers did respectably. Sandstorm managed a time just ten minutes behind the winner while her sister vehicle Highlander came in ten minutes after that. GrayBot and TerraMax, the other two course-completers, came in at seven hours 30 minutes and 12 hours 51 minutes, respectively.
So smart, autonomous vehicles can, indeed, find their way across several hundred kilometres of desert. The question is, what next？ DARPA's answer, of course, will be to go down the military route. But this sort of technology has obvious civilian applications as well, as Sebastian Thrun, the head of both SAIL and the Stanford racing team, is keen to emphasize.
Dr. Thrun thinks that it could lead to self-driving road vehicles within 30 years and—more immediately—to greatly improved collision-avoidance systems. Whether the freeways of California will prove as easy to navigate as the gulches of Nevada, though, remains to be seen.
The purpose of holding a robot race is to
A．adventure through the Nevada desert.
B．delevop unpiloted vehicles for military use.
C．win a $lm jackpot.
D．keep American troops unharmed.
Which of the following is strongly against cloning research？
A．The National Institutes of Health.

Anybody who's ever worked in a hospital sees the hospital is full of patients that have alcohol related disease, but the hospital is not full of patients that have disease related to cholesterol and blood pressure-lowering medicines.
In an editorial in the current New England Journal of Medicine, Dr. Goldberg of Columbia University said it is time to see whether alcohol actually prevents heart disease. Such a study would give alcoholic beverages to one group of heart disease patients and not to another, and see which does better.
In the latest study, which followed a group of men over a 12-year period, researchers found that those who drank three or more drinks per week reduced their risk of heart attack by 35 percent compared to abstainers.
The lead author, physician Kenneth Mukamal of Beth Israel Deaconess Medical Center in Boston, insists his study is different from the rest. For one thing, other studies have not looked at drinking patterns.
Dr. Mukamal says his findings also appear to settle which alcoholic beverages are most heart healthy. "Beer and spirits, beer and liquor, were most strongly associated with reduced risk."
