Question: Article: The story began on a downtown Brooklyn street corner. An elderly man had fallen down while crossing the street , and an ambulance rushed him to the nearest hospital. There, when he came to now and again, the old man repeatedly called for his son. From a worn letter located in his pocket, an emergency-room   nurse learned that his son was a sailor stationed in North Carolina Camp. Obviously there were no other relatives. Someone at the hospital called the Red Cross office in Brooklyn, and a request for the son to rush to Brooklyn was sent. Because time was short--the patient was dying, so they found the young man and rushed him to the airport in time to catch the only plane that night enable him to reach his dying father. It was dusk when the nurse took the tired, anxious sailor to the bedside. "Your son is here," she said to the old man. She had to repeat the words several times before the patient's eyes opened. The medicine he had been given because of the pain from his heart attack made his eyes weak and only saw the young man in uniform( ) standing outside the oxygen tent. He extended his hand. The sailor wrapped his strong fingers around the old man's, releasing a message of love and encouragement. The nurse brought him a chair, so the sailor could sit by the bed. Nights are long in hospitals, but all through the night the young sailor sat there, holding the old man's hand and offering words of hope and strength. It was nearly dawn when the patient died. The sailor placed his lifeless hand he had been holding on the bed, and went to inform the nurse. "Who was the man?" the sailor asked. "He was your father." the nurse answered surprisingly. "No, he wasn't," the sailor replied." I never saw him before in my life." "Why didn't you say something when I took you to him?" she asked. "I knew immediately there'd been a mistake, but I also knew he needed his son, and his son just wasn't here. When I realized he was too sick to tell whether or not I was his son, I guessed he really needed me. So I stayed." Two days later a message came in that there had been two sailors with the same name and similar number in the Camp. Someone in the personnel office had pulled out the wrong record. But _ And he proved, in a very human way, that there are people who care what happens to their fellow men.

Question: 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

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


Question: Article: New York City schoolchildren can't use cellphones at school because of Mayor Michael R. Bloomberg's ban on cellphones in schools. Many parents are opposed to Mayor Michael R. Bloomberg's ban on cellphones in schools by e-mail messages. There was a 13-year-old student who was shot with a gun after school, unable to call his mother for help. There was a high school student robbed three times last year, twice in her school building. There was a girl who got a piece of glass placed in her eye during school and was saved from a possible cornea transplant   only because, having disobeyed the cellphone ban, she was able to call her mother and get an operation on time. The ban has been on for years, but it set off a widespread parental outcry only in April, after some headmasters sent home letters reminding parents that cellphones are not allowed to be brought into school. Mr Bloomberg has defended the ban, saying that cellphones are bad and often used to cheat or call in friends for fights. If something is important, he says, parents can call schools directly. On the other hand, many of the e-mail messages from parents described the ban as "cruel and heartless", "absurdly  wrong-headed", "anti-parent", "ridiculous". "We respect the fears that parents have," David Cantor, a spokesman for Schools Minister Joel I. Klein said, "but after all the fact is that having phones in schools always leads to more problems."
