注意事項(xiàng)
It used to be that nations were more or less successful in their competition with other nations depending upon the quality of their transportation infrastructure.
過去的情形是一個(gè)國(guó)家在與其它國(guó)家的競(jìng)爭(zhēng)中取勝的程度取決于其運(yùn)輸基礎(chǔ)設(shè)施的質(zhì)量。
The nation with the best deep water ports or the most efficient railroads had a competitive advantage over others.
具有深水良港和高效鐵路的國(guó)家也擁有戰(zhàn)勝其它國(guó)家的強(qiáng)大優(yōu)勢(shì)。
And we began to think of infrastructure in those terms.
因而我們開始考慮這方面的基礎(chǔ)設(shè)施。
After WWII when tens of millions of American families first purchased automobiles.
二戰(zhàn)時(shí)，千萬個(gè)美國(guó)家庭首先購(gòu)買了汽車，
and thousands of businesses began to rely on trucks every single day.
上千家企業(yè)每天都離不開卡車，
we quickly found our network of two lane highway to be hopelessly inadequate.
在此之后，我們很快發(fā)現(xiàn)，兩車道公路網(wǎng)絡(luò)是滿足不了要求的。
And so we built a network of interstate highways and that contributed enormously to our post war economic dominance of the world.
因而又建造了州際高速公路網(wǎng)絡(luò)，此舉極大地促進(jìn)了戰(zhàn)后我們的經(jīng)濟(jì)主導(dǎo)地位。
Today,commerce rolls not just on asphalt highways but along information highways
當(dāng)今商業(yè)動(dòng)作不僅是在瀝青高速公路上，也要在信息高速公路上進(jìn)行，
and tens of millions of American families and businesses now use computers,
幾千萬美國(guó)家庭和商業(yè)目前都使用著計(jì)算機(jī)，
and find that the two lane information roads built for telephone service are no longer adequate.
并且發(fā)現(xiàn)用于電話業(yè)務(wù)的兩道信息公路已遠(yuǎn)不能滿足需求。
It's not that we have a shortage of information.
并不是缺少信息。
Indeed,we often now have a lot more than we know what to do with...
相反，我們所得到的信息多得常常使我們不知所措。
Take just one brief example:the LandSat satellite.
興一個(gè)LanSat衛(wèi)星的簡(jiǎn)單的例子。
We're trying to understand the global environment,
我們想探測(cè)全球環(huán)境，
and the LandSat satellite is capable of taking a complete photograph of the earth surface every eighteen days,
LanSat衛(wèi)星能每隔18天拍攝一次地表面的完整照片，
and it's been up there for twenty years.
此項(xiàng)任務(wù)已經(jīng)進(jìn)行了二十年。
And yet 95 per cent of all of the images it has made have never been seen by human eyes...
大約該衛(wèi)星拍攝的照片有95％是人所從未見過的。
Now,we have an insatiable hunger for knowledge,as we try to find the information we need to solve the challenging problems that confront us.
現(xiàn)在當(dāng)我們?cè)O(shè)法找到解決我們所遇到的挑戰(zhàn)性問題的信息時(shí)我們對(duì)知識(shí)的渴求永無止境。
And yet in many cases the information just sits rotting away unused.
但是在許多情況下這些信息卻是閑置著以至失去價(jià)值。
