Dear Mr. Brown,
Thank you for your letter of 6 September regarding Mr. John Green who has been employed by this company for the past 10 years.
Mr. Green served his apprenticeship (学徒) with Vickers Tools Ltd. in Manchester, followed by a three-year course of engineering for Production Engineers. He is technically well—qualified and for the past five years has been our Assistant Works Manager responsible for production and related business in our Sheffield factory. In all his job duties he has shown himself to be hard-working, responsible and in every way a very dependable employee.
I can strongly recommend Mr. Green as I feel sure that if he were to be chosen to manage your factory in Nairobi he would bring to his work a true atmosphere of teamwork, which would be found necessary and helpful by all who would work with him.
Sincerely yours，
Tom Smith

“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.

A.They keep America's economy running healthily.
B.They prove to be a good alternative to petroleum.
C.They do not provide a sustainable energy supply.
D.They cause serious damage to the environment.
63. Why does America rely heavily on oil imports？()
A.It wants to expand its storage of crude oil.
B.Its own oil reserves are quickly running out.
C.It wants to keep its own environment intact.
D.Its own oil production falls short of demand.

I have learned something about myself since I moved from Long Island to Florida three years ago. Even though I own a home in Port St. Lucie just minutes from the ocean, an uncontrollable urge wells up to return to Long Island even as others make their way south. I guess I am a snowbird stuck in reverse. Instead of enjoying Florida’s mild winters, I willingly endure the severe weather on Long Island, the place I called home for 65 years.
I’m like a migratory bird that has lost its sense of timing and direction, my wings flapping against season.
So what makes me fly against the tide of snowbirds？ The answer has a lot to do with my reluctance to give up the things that define who I am. Once I hear that the temperature on Long Island has dipped into the range of 40 to 50 degrees, I begin to long for the sight and crackling sound of a wood fire. I also long for the bright display o￡ colors — first in the fall trees, and then in the limits around homes and at Rockefeller Center. Floridians decorate too, but can’t create the special feel of a New England winter.
I suppose the biggest reason why I return is to celebrate the holidays with people I haven’t seen in months. What could be better than sitting with family and friends for a Thanksgiving turkey dinner, or watching neighbors’ children excitedly open gifts on Christmas？ Even the first snowfall seems special. I especially enjoy seeing a bright red bird settling on a snow-covered branch (My wife and I spend winters at a retirement community in Ridge, and I’m grateful that I don’t have to shovel.)
While these simple pleasures are not unique to Long Island, they are some of the reasons why I come back. Who says you can’t go home？
