科学实验活动册系列答案Made In The USA: An Export Boom
In his State of the Union address two years ago, President Obama argued that in order to recover from the economic recession, one of the few things the U．S. needed to do was to export more goods around the world. That night, the president unveiled a new goal: to double U．S. exports over the next five years. It would be an increase that the president said would “support two million jobs in America.”
Most economists dismissed the promise at the time as something unrealistic, but two years later, the U．S. is on pace to meet that goal. American exports are up 34 percent since the president gave that speech, and the number continues to rise.
Competitive In A Global Market
Marlin Steel, a metal working business in Baltimore, makes parts that ship all across the world. “We export to 36 countries，” owner Drew Greenblatt tells All Things Considered Host Guy Raz. “We're working around the clock, and we're growing.”
It's not just advanced manufacturing exports on the rise, but pork, cattle and all kinds of agricultural exports are up as well. Even American craft beer has found an export market.
Flying Dog CEO Jim Caruso says that increasingly, people all over the world are trying the beer from the Maryland-based brewery. Caruso says，“Even in those top beer-producing countries, a competitive American product is finding a market.”
Services Are Exports, Too
Another place exports are coming from is New York City—in particular, the 30th floor of a Manhattan skyscraper on 5th Avenue and 52nd Street. That's where the consulting firm Kurt Solomon lies. It doesn't actually produce a product for export; it provides management advice and strategy.
“Four out of every five Americans is now employed in the service industry，” the nation's top trade official, Ron Kirk says, “Services are a significant part of our exports, and make up about a quarter of our exported goods.” These services can include everything from legal consulting, finance, information technology and even engineering.
And There Are Other Factors
So why has there been an increase of more than 30 percent for exports in almost everything? Part of the increase, at least for the manufacturing side, is due to better technology, says Tyler Cowen, an economist. “A lot of it is being driven by smart machines，” he tells Raz，“The U．S. has high wage rates, which is a disadvantage, but if machines are doing a lot of the work, that doesn't matter.”
China factors a lot in America's export economy, too. “Wages in China have been going up as the country becomes more productive. Thus China is losing the cheap labor advantage it has held for some time.” Cowen says.
Will Jobs Grow, too?
“Companies have become more productive by dismissing workers and lowering costs.” Cowen says. “So I don't view exporting as a way of creating a very large number of jobs, but it will create more profits.”
So not every business or worker is necessarily benefiting from the export boom in the U．S., and Cowen says that could ultimately lead to a polarization (两极) of economic outcomes.

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism (新陈代谢) becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious（恶性的） circle in its tracks, people need to consume food and supplements that will neutralize the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.
