托福听力练习对照文本

I want to welcome each and every balloon enthusiast to Philadelphia.

我想要欢迎每一位气球爱好者来到Philadelphia

Thank you for coming here this morning to commemorate the first balloon voyage in the United States.

感谢大家今天早上来到这里纪念在美国的第一次气球航行。

On January 9, 1793, at ten o'clock in the morning, a silk balloon lifted into the skies above this city, which was, at the time, the capital of the country.

在1793年1月9日，上午十点钟，一个丝质气球在这个城市上空升起，这里，在当时，是国家的首都。

According to the original records of the flight, the voyage lasted forty-six minutes, from its departure in Philadelphia to its landing across the Delaware River in New Jersey.

根据飞行的原始记录，这次航行持续了46分钟，从它的出发地Philadelphia到它穿过Delaware河着陆在New Jersey。

Though our pilots today will try to approximate the original landing site, they're at the mercy of the winds, so who knows where they'll drift off to.

虽然我们的飞行员今天将试图去接近最初的着陆地点，他们还要受到风的支配，所以谁知道他们将飘到哪里去。

Even the balloonist in 1793 experienced some uncertain weather that day.

即使是在1793年，气球驾驶者那天也经历了一些变幻莫测的天气

There were clouds, fog, and mist in various directions.

有云，雾，并且薄雾在不同的方向上。

Our reenactment promises to be nothing less than spectacular.

我们的场景重现，发誓要成为完全的盛景。

The yellow balloon directly behind me is five stories high.

在我正后方的黄色气球有五层楼高。

It's inflated with helium, unlike the original, which was filled with hydrogen and, unbeknownst to the pilot, potentially explosive.

它充满了氦气，和原来不同，那个是充的氢气，飞行员不知道的是，有爆炸的可能性。

Gas-filled models are pretty uncommon now because of the extremely high cost, so the eighty other balloons in today's launch are hot air, heated by propane burners.

因为极高的成本，充气的型号现在很少见。所以今天起飞的另外80是个气球是热气(球)，由丙烷燃烧器加热。

These balloons are from all over the country.

这些气球来自全国各地。

A lot of people in the United States are coffee drinkers.

在美国，很多人都是喝咖啡的人

Over the last few years, a trend has been developing to introduce premium, specially blended coffees, known as "gourmet coffees" into the American market.

在过去的几年里，已经发展出一种趋势，引进高价的，特殊调制的咖啡，被称作“美味咖啡”，到美国的市场。

Boston seems to have been the birthplace of this trend.

Boston似乎是这一趋势的诞生地

In fact, major gourmet coffee merchants from other cities like Seattle and San Francisco came to Boston, where today they're engaged in a kind of "coffee war" with Boston's merchants.

事实上，大多数来自其他的城市诸如Seattle 和 San Francisco的美味咖啡商人们来到了Boston，今天他们在这里参与进了同Boston的商人们的某种“咖啡战争”

They are all competing for a significant share of the gourmet coffee market.

他们都在为美味咖啡的一个重要市场份额竞争

Surprisingly, the competition among these leading gourmet coffee businesses will not hurt any of them.

令人惊讶的是，在这些主要的美味咖啡生意之间的竞争，将不会伤害他们中的任何人。

Experts predict that the gourmet coffee market in the United States is growing and will continue to grow, to the point that gourmet coffee will soon capture half of what is now a 1.5-million-dollar market and will be an 8-million-dollar market by 1999.

专家们预测美味咖啡的市场在美国正在增长并将持续增长，达到这种程度：美味咖啡将很快夺得现在150万美元的市场份额的一半，并将在1999年达到800万美金的市场份额

Studies have shown that coffee drinkers who convert to gourmet coffee seldom go back to the regular brands found in supermarkets.

研究已经表明，喝咖啡的人一转喝美味咖啡，很少回到常规的，在超市中找到的品牌

As a result, these brands will be the real losers in the gourmet coffee competition.

结果，这些品牌将在美味咖啡竞争中成为真正的输家
