“Energy independence” and its rhetorical (修辞的) companion “energy security” are, however, slippery concepts that are rarely though through. What is it we want independence from, exactly？
Most people would probably say that they want to be independent from imported oil. But there are reasons that we buy all that old from elsewhere.
The first reason is that we need it to keep our economy running. Yes, there is a trickle(涓涓细流)of biofuel(生物燃料)available, and more may become available, but most biofuels cause economic waste and environmental destruction.
Second, Americans have basically decided that they don't really want to produce all their own oil. They value the environmental quality they preserve over their oil imports from abroad. Vast areas of the United States are off-limits to oil exploration and production in the name of environmental protection. To what extent are Americans really willing to endure the environmental impacts of domestic energy production in order to cut back imports？
Third, there are benefits to trade. It allows for economic efficiency, and when we buy things from places that have lower production costs than we do, we benefit. And although you don't read about this much, the United States is also a large exporter of oil products, selling about 2 million barrels of petroleum products per day to about 90 countries.
There is no question that the United States imports a great deal of energy and, in fact, relies on that steady flow to maintain its economy. When that flow is interrupted, we feel the pain in short supplies and higher prices, At the same time, we derive massive economic benefits when we buy the most affordable energy on the world market and when we engage in energy trade around the world.

But I do not agree with the opinion that women have to show their beauty through their looks. The richness of their mind proves to be more beautiful and attractive than their looks. A woman who has experienced many troubles and may be called "aunt" or "granny" can still maintain her beauty if she has such excellent qualities as knowledge, ability, a kind heart and concern for others.
In addition, old and young, beautiful and ugly are relative concepts. People who keep a young mind will never feel old. Curious about new things and eager to learn more, they keep up with the tide. Plainly dressed women may have a type of beauty, which is pure and real.
Reading and learning is the best way to keep one youthful. Good books are fertile soil which can feed the flower of one's heart and looks.
