PROBLEM: Article: The United States is the world's largest consumer of energy. We use electricity, gas and oil to light and heat our buildings and run our cars. The demand for power is growing. But we may not need to build new power plants or find more oil. The best way to increase our supply of energy is to be more efficient. Did you know that when you leave your video-game console on, it consumes more electricity than two refrigerators? Or that those funny-looking, twisty bulbs use 75% less power than traditional light bulbs? We have the tools to save money, reduce pollution and even help our planet, simply by wasting less energy. As President, Barack Obama plans to make energy efficiency in American a major goal. He has promised to cut 15% of all energy used by the Federal Government. In a speech, he called for 75% of government office buildings to be updated for better efficiency. He pointed out that energy-efficient buildings and homes will save consumers billions of dollars on energy bills. An "extra benefit", he added, will be "a cleaner, safer planet." Gas, coal and oil are called fossil fuels. Fossil fuels have been the world's main source of energy for hundreds of years. But burning them releases dirty gases, which cause pollution. There are two main ways to save energy. The first is to use more efficient machines. Hybrid cars use less gas. New appliances are designed to use less electricity. Today's refrigerators are three times more efficient than those before 1973. Laptop computers consume much less energy than desktop computers. The second is to use machines more productively. According to the US Department of Energy, in the average home, 75% of the electricity used to power electronic equipment is standby power . That means power flowing to plugged-in appliances whether or not they are being used. Homeowners can avoid wasting power by pulling the plug on appliances when they are not in use. Efficiency experts argue that today's best techniques could cut US oil and gas use in half, and reduce our electricity use by three-fourths.
Answer: the US is determined to improve energy efficiency in the whole America

SOLUTION: By referring to Obama's plan, the author mainly intended to say that _

PROBLEM: Article: In Vietnam, two members of a family of street vendors are finding a way to help the poorest students in Hanoi. Pham Minh Dap and his brother are providing the students with mostly free English and Japanese lessons at a learning center they created. The men want to help people who would not normally have a chance to learn a foreign language. Some education experts in Vietnam say such knowledge may help college graduates get jobs. The country's economy has improved. But many graduates continue to have a hard time finding employment. Local media reported ten percent of university graduates do not have a job. Earlier this year, 24-year-old Pham Minh Dap and his brother established a school they call "Stand By You". Volunteers teach poor students English and Japanese. Many classes are free. Students with some language knowledge pay 25 to 50 cents per class. Mr. Dap pays about $ 500 to rent the language center space and for other costs. He gives about $ 150 from his earnings as a street Vendor and private language teaching. His brother gives the same amount from the money he earns as a secretary. Friends provide the rest. Mr. Dap and many of his family members have sold things outside HoaBinh Park in the center of Vietnam's capital for five years. They come from a village of rice farmers in Thanh Hoa Province. Twenty-four-year-old Pham THi Trang is one of 600 students at the language school. She is finishing her university studies. Her parents work in a market in a village in Ha Nam Province. She says life is hard in the city. She earns about $50 a month from a part-time job, and her parents give her $ 75. But this is not enough to live on. She has said she has to be very careful with money so she can pay her bills. Demand for the school is growing. About 1,000 people are on a waiting list to enter. Ten people have offered to teach for free. And Mr. Dap says he is hoping to raise money to pay for a bigger place. He wants to open more classes.
Answer: by two brothers

SOLUTION: "Stand By You" is established _ .

PROBLEM: Article: On Sept. 11, an unseen enemy launched an attack on economic, military and governmental Landmarks of the United States. Beyond the tremendous loss of innocent lives and physical property, the attack was clearly aimed at the ideals of America--our values and the economic system that has made the U.S. economy the envy of the world. Those responsible for these acts portray the United States as the embodiment of all that is evil With globalization and the worldwide economy it has spawned. They use the failures of globalization as an excuse to exploit their millions of constituents in the underdeveloped world. Sometime soon, the U.S. military will strike back against those who it is determined have committed these acts. A military response is appropriate - some would say overdue . But even if the military objective is achieved, that alone will not get to the heart of the matter. It is crucial that the U.S. economy return to full speed ahead and continue to be the driving force behind expansion of the global economy. Globalization, or at least the present phase of it, generally is viewed as having started with the end of the Cold War in 1989. And for all its shortcomings, the free flow of goods, services, capital and labor across the borders of the world's trading nations -- the process that has come to be called globalization--still offers the best chance to fulfill the dreams of so many of the world's poor.
