WASHINGTON - Barack Obama swept to victory as the first black president in the US history Tuesday night in an electoral college landslide that overcame racial barriers as old as America itself. "Change has come," he told a huge group of cheering supporters. In his first speech as victor, Obama catalogued the challenges ahead. "The greatest of a lifetime," he said, "two wars, a planet in danger, the worst financial crisis in a century." He added, "There are many who won't agree with every decision or policy I make as president, and we know that government can't solve every problem. But I will always be honest with you about the challenges we face." The son of a black father from Kenya and a white mother from Kansas, the Democratic senator from Illinois sealed his historic triumph by defeating Republican Sen. John McCain in a string of wins in hard-fought battleground states -- Ohio, Florida, Virginia, Iowa and more. In his speech, Obama invoked   the words of Lincoln and echoed John F. Kennedy. "So let us summon a new spirit of patriotism, of service and responsibility where each of us resolves to pitch in   and work harder," he said. He and his running mate, Joseph Biden of Delaware, will take their oaths of office as president and vice president on Jan. 20, 2009. Obama will move into the Oval Office as leader of a country that is almost certainly in recession  , and fighting two long wars, one in Iraq, the other in Afghanistan. Obama has said his first order of presidential business will be to tackle the economy. He has also pledged to withdraw most US combat troops from Iraq within 16 months. The first issue Obama will focus his attention on may probably be to   _  . A) withdraw most US combat troops from Iraq B) care for environmental protection C) declare two wars in Iraq and Afghanistan D) deal with the problems of economy

How often do you go on holiday? Going on holiday makes you feel good while you're there-you gain the health benefits for months, new research shows. Jetting off to exotic destinations such as the Maldives cuts your blood pressure, helps you sleep better and bounce back from stress, it found. The benefits last at least a fortnight longer than the vacation and can be felt for months in some cases where it is claimed. Experts say workers should always take their full holiday entitlement each year-as many as one in three don't-to get the benefits. The study compared key health markers in holidaymakers visiting Thailand, Peru or the Maldives, with people who stayed at home and continued working. The average blood pressure of those on holiday dropped by 6% while the workers saw their blood pressure rise by 2% over the same period. The sleep quality of holiday-makers improved by 17% while that of the non-holidaymakers _ by 14%. The study also found the ability of vacationers to recover from stress--known as the stress-resilience test-improved by 29%. There was a 71% fall in stress resilience scores among workers. Test showed a fall in blood glucose levels, reducing the risk of diabetes, trimmer waistlines and enhanced mood and energy levels, with the effects sustained for at least 2 weeks after returning home. The Holiday Health Experiment was conducted by tour operator Kuoni and Nuffield Health, the UK's largest healthcare charity. The author intends to tell us that   _  . A) it is best to go to foreign countries like Maldives. B) we had better go on holiday for the benefits of health C) we have to go on holiday as much as possible D) you'll certainly get depressed if you don't go on holiday

Q: What is your earliest childhood memory? Can you remember learning to walk? Or talk? The first time you watched a television program? Adults seldom call back events much earlier than the year or so before entering school, just as children younger than three or four seldom remember any specific, personal experiences. A variety of explanations have been suggested by psychologists   for this "childhood amnesia". Now Annette Simms, a psychologist of Riverdale University, offers a new explanation for childhood amnesia. According to Dr. Simms, children need to learn to use someone else's spoken description of their personal experiences in order to turn their own short-term, fast forgotten impressions of them into long-term memories. In other words, children have to talk about their experiences and hear others talk about them. Without this verbal reinforcement  , children cannot form permanent memories of what they have experienced. So why should personal memories depend so heavily on hearing them described? Dr. Simms presents evidence that the human mind organizes memories in that way. Children whose mothers talk with them about the day's activities before bedtime tend to remember more of the day's special event than those whose mothers don't. Talking about an event in this way helps a child to remember it. And learning to organize memories as a continuous story is the key to a permanent mental "autobiography  " of important life events. Dr. Simms suggests that we humans may be biologically programmed to turn our life experiences into a novel. The key to creating this mental life story is language, says Dr. Simms. "Children learn to talk about the past," she says. "Talking to others about their short-term memories of the past leads to the establishment   of long-term memories." One way it does this is by helping a child to recognize that the retelling of an experience is just the experience itself, recreated in the form of words. The child learns that this "word-description" of an experience can then be stored in... To form permanent memories of their experiences, young children need to   _  . A) talk about them with others B) grow older than three or four C) write a story in their own language D) have a good relationship with their parents

*Question*
George Gershwin, born in 1998, was one of America's greatest composers. He published his first song when he was eighteen years old. During the next twenty years he wrote more than five hundred songs. Many of Gershwin's songs were first written for musical plays performed in theatres in New York City. These plays were a popular form of entertainment in the 1920s and 1930s. Many of his songs have remained popular as ever. Over the years they have been sung and played in every possible way -- from jazz to country. In the 1920s there was a debate in the United States about jazz music. Could jazz, some people asked, be considered serious music? In 1924 jazz musician and orchestra leader Paul Whiteman decided to organize a special concert to show that jazz was serious music. Gershwin agreed to compose something for the concert before he realized he had just a few weeks to do it. And in that short time, he composed a piece for piano and orchestra which he called Rhapsody in Blue. Gershwin himself played the piano at the concert. The audience were thrilled when they heard his music. It made him world-famous and showed that jazz music could be both serious and popular. In 1928, Gershwin went to Paris. He applied to study composition  with the well-known musician Nadia Boulanger, but she rejected him. She was afraid that classical study would ruin his jazz-influenced style. While there, Gershwin wrote An American in Paris. When it was first performed, critics  were divided over the music. Some called it happy and full of life, to others it was silly and boring. But it quickly became popular in Europe and the United States. It still remains one of his most famous works. George Gershwin died in 1937, just days after doctors learned he had brain cancer. He was only thirty-nine years old. Newspapers all over the world reported his death on their front pages. People mourned the loss of the man and all the music he might have still written. What did Gershwin do during his stay in Paris? A) He created one of his best works B) He studied with Nadia Boulanger C) He argued with French critics D) He changed his music style
