2、 hopes were high. The challenge: to drive a vehicle without a human driver or remote control some 150 miles (241 kilometers) through the Mojave Desert.But those hopes quickly went up in a cloud of dust as most robots barely managed to get off the starting line. The best performer, a modified Humvee
3、built by engineers at Pennsylvanias Carnegie Mellon University, traveled 7 miles (11 kilometers) before breaking down.To robot devotees (热爱者), however, it was a minor hiccup.No surprise, then, that 43 teams showed up to try out for this years race, dubbed (被称作) the Grand Challenge. For the past week

8、ate in dangerous environments, such as war zones, keeping soldiers out of harms way.A U.S. Congress mandate (训令) requires that one-third of military ground vehicles drive themselves by 2015, but the technology to meet that mandate does not yet exist.So the government looked to enterprising teams to
9、develop the technology for driverless vehicles, sweetening its offer with the two-million-dollar purse.None of the 23 teams knows what lies ahead for this years race. DARPA wont reveal the exact route until two hours before the start of the race on Saturday.But the obstacles on the Fontana qualifica

11、liffs. The computers brain has to figure out how to resolve unexpected conflicts, like a boulder sitting in the middle of the road.“Think about all the decisions that you and I have to make when we drive from our house to the store,“ Kurjanowicz said. “These vehicles have to do the same thing, witho
12、ut a driver.“Among the top contenders in Saturdays race is TerraMax, a massive truck originally built by the Wisconsin-based Oshkosh Truck Corporation for the U.S. Marine Corps.In last years race, TerraMax managed to go only 1.2 miles (2 kilometers). Team leader Gary Schmiedel expects to do much bet

He pointed to the new all-wheel steering feature on the truck as an important addition.“We can move this large, 15-ton (13.5-metric ton) payload vehicle in a turn thats equivalent to that of a Humvee,“ he said.BGhostrider/BThe resources of teams like TerraMax or Carnegie Mellon Univer

It has a
15、beer keg (小桶) stuck on the back and an on-offswitch that says “brain.“Most of the schools and organizations were up against are just accessorizing conventional vehicles,“ said team leader Chris “C.J.“ Pedersen, a former actor. “Our vehicle is a custom-built, 21st-century hot plete with hood scoop an

Studded with sensors and computers, it toppled (翻倒) over after 3 feet (1 meter) in last years race.Levandowski, who had to postp

This bike costs as much as a tire or a wheel of some of these other guys machines.“BSmart Money/BNeither Ghostrider nor It Came From the Garage made the final cut at this weeks qualifying races.However, another crowd-pleaser, Cajunbot-or the Ragin Cajun-a converted all-terrain vehicle

Experts have been interested in these effects and have agreed on five basic stages of culture shock. These stages ar
40、e general and should only be used as a reference. Not every individual will go through each stage, and one stage may last longer than another for different individuals.The hardest thing for most travelers to deal with is the emotional “roller coaster“ they seem to be riding. One moment they feel ver
41、y positive toward the new culture, and the next moment very negative. It seems common that international visitors and immigrants vacillate (犹豫不定) between loving and hating a new country. Feelings of separation and alienation can be intensified if they do not have a sense of fitting in or belonging.F
42、atigue is another problem people face when entering a new culture. There can be a sense of a greater need for sleep. This is due not only to physical tiredness, but also to mental fatigue. This mental fatigue comes from straining to comprehend the language, and coping with new situations.The impact
43、of culture shock can vary from person to person. There can be significant differences because some people may be better prepared to enter a new culture. Four factors which play into these are personality, language ability, length of stay, and the emotional support received.It is logical to think tha
44、t when people are deprived of their familiar surroundings they will feel disoriented. One solution some have found is to bring a few small reminders of home. Pictures, wall hangings, favorite utensils, and keepsakes (纪念品) are all good candidates to make things feel more familiar. Another helpful act
45、ivity is to establish little routines that become familiar over time. Even better is fitting things that were part of the regular routine back in the home country into the routine established in the new culture. This will make people feel more at home.（分数：90.00）(1).According to the 1st paragraph, ex
