CNN News：美股新记录

Including General Electric, there are now 30 stocks listed in the Dow. They're called Blue Chips, stocks from companies that are financially strong andconsidered good investments. The Dow Jonesaverage is one indication how the U.S. economy isdoing and it hit a milestone last week. It passed 25,000 points.

包括通用电气公司在内，道琼斯指数有30支成份股。这些股票被称为蓝筹股，这些股票通常来自那些财力雄厚、被视为值得投资的公司。道琼斯平均指数是美国经济表现的一个信号，而上周，该指数创造了里程碑。这一指数突破了25000点大关。。

But it's not just the Dow's new high mark that made news. It's the speed at which the indexreached the record. For the Dow to go from 5,000 points to 10,000, which it did back in the 1990s, it took more than three years. The index just jumped from 20,000 points from 25,000 in less than 12 months. Analysts say this is because the U.S. economy is growing faster andthat companies profits are high.

而成为新闻的不只是道指创下新高。道指的增速也创下了记录。上世纪90年代，道指从5000点涨至10000点，这一过程历时三年多的时间。而道指从20000点涨至25000点只用了不到12个月。分析人士表示，这是因为美国经济的增速更快，公司的利润也更高。

Some economists say it's possible for the economy to overheat, to grow too fast and causeinflation, when prices rise and people aren't able to buy as much. That could trigger a seriesof actions that could reverse economic growth.

一些经济学家认为，美国经济可能过热，经济增长可能过快，并导致通货膨胀，通货膨胀指物价上涨，人们的购买力下降。这可能引发一系列会扭转经济增长的操作。

Others say there's still plenty of room for the economy to grow without overheating. And if itdoes that, it's anyone's guess how high the Dow can go.

其他人则认为，经济在不会过热的情况下仍有很多增长空间。如果是这样，那人们都在猜测道指会涨至多高。
