One summer I was driving from my hometown of Tahoe City, California, to New Orleans. In the middle of the desert, I came upon a young man standing by the roadside. He had his thumb out and held a gas can in his other hand. I drove right by him. There was a time in the country when you’d be considered a stupid person if you passed by somebody in need. Now you are a fool for helping. With gangs, drug addicts, murderers, thieves everywhere, “I don’t want to get involved” has become a national motto.

Several states later I was still thinking about the hitch-hiker(免费搭车的人). Leaving him standing in the desert did not bother me so much. What bothered me was how easily I had reached the decision. I never even lifted my foot off the accelerator(加速器).

Does anyone stop any more? I wondered. I recalled Blanche DuBois’s family line: “I have always depended on the kindness of the strangers”. Could anyone rely on the kindness of the strangers these days? One way to test this would be for a person to journey from coast to coast without any money, relying only on the good will of his fellow Americans. What kind of Americans would he find? Who would feed him, shelter him, and carry him down the road?

The idea interested me.

So I decided to travel from the Pacific to the Atlantic without a penny. It would be a cashless journey through the land of the almighty dollar. I would only accept offers of rides, food and a place to rest my head. My final destination would be Cape Fear in North Carolina, a symbol of all the fears I’d have to conquer during the trip.

I rose early on September 6, 1994, and headed for the Golden Gate Bridge with a 50-pound pack on my back and a sign displaying my destination to passing vehicles: “America”.

For six weeks I hitched 82 rides and covered 4,223 miles across 14 states. As I traveled, folks were always warning me about someplace else. In Montana they told me to watch out for the cowboys in Wyoming; in Nebraska they said people would not be as nice as in Iowa. Yet I was amazed by people’s readiness to help a stranger, even when it seemed against their own best interests.

A.Making the decision of not offering help so easily.

文化扶贫即从文化和精神层面上给予贫困地区以帮助,从而提高当地人民素质,尽快摆脱贫困。建国后,特别是近十几年来,党和政府为加大对革命老区、民族地区、边疆地区、贫困地区发展的扶持力度,大力开展文化扶贫。文化部认真贯彻落实党中央、国务院关于扶贫工作的要求,提出了“文化扶贫为主,多种扶贫方式并举”的工作思路。

多年来,农村工作的实践证明,“治贫”必先“治愚”,大力发展农村的文化事业,提高农民的思想文化素质和科学技术水平,是促进农村经济发展,从根本上改善农民生活的关键所在。正如贫困地区农村干部所说的,“没有文化富不了,有了文化穷不长。”因此,针对广大贫困地区农村文化水平落后,农民文化生活贫乏,观念习俗滞后的现实,开展文化扶贫,是当前一项十分紧迫而重要的工作。

某地文化扶贫实施“万村书库”工程,即建起一座小型图书室,并向每座图书室赠书100种。向农村捐赠图书,培养了当地人员的文化素质和干部的应用写作能力。

运用所学的文化生活知识,说明“没有文化富不了,有了文化穷不长”的道理。
