user: Article: So you think you know your dog. But how well does your dog know you? She probably recognizes you when she sees you. But can a dog tell by simply looking at you whether you have a happy or an angry expression on your face? Researchers in Austria have taught pet dogs to know the difference. Dogs are very mindful of sound. When dog owners shout or speak in a strong, unkind voice, dogs often act ashamed and quietly move away from the area. Recently, researchers found that dogs can look at our faces, and tell the difference between a smile and a frown . The animals were able to recognize a look of praise from one of blame. Researchers at the University of Veterinary Medicine, Vienna performed a series of experiments. They taught dogs to recognize facial expressions. They showed the dogs two pictures of either the upper or lower half of a person's face. On one picture, the person looked happy. The other appeared angry. The dogs were then shown images of the eyes or mouths of people they had never seen before. They were also shown the left half of the faces used in training. Corsin Muller led the study. "We were really speaking, do they realize that smiling eyes have the same meaning as a smiling mouth, or angry eyes have the same meaning as an angry mouth? And it turned out that they really did perform very well in these research experiments." Once the dogs learned to recognize which image was happy or angry, they could easily find the same expressions in pictures of any face. Corsin Muller says future studies will try to show whether dogs can learn the meaning of facial expressions--for example, whether a frown shows that someone is angry. In the experiments, researchers found the dogs were slower to link a reward, or prize, with recognition of the angry face. This suggested that dogs had an idea people with angry faces were best avoided. Question: What can we learn from the passage? Yes or no, is the answer "Dogs can understand man's feelings."?

Article: With limited pocket money in hand,many Chinese college students are increasingly opting to live life "low cost".One way to save money is teambuying.Online teambuying offers huge discounts and becomes popular on campus. Li Jing,a student at China Youth University for Political Sciences,for example,says she often buys movie tickets on teambuying websites.But while they offer a good opportunity to save money,Li said she would "think twice before buying them from online stores".Because many of them are "a bit chaotic  ",and have fake goods mixed among them.Then why don't the students just earn more pocket money by taking up parttime jobs?Guo Na,a teacher at the Communication University of China,said most college students were unlikely to choose workstudy programs to earn pocket money because of their intensive study schedules. A kind of card called "VELO" has become another ideal choice for many money savers.It provides allround discounts while dining out or shopping in general.Cao Zuyang,a student at the University of Electronic Science and Technology of China,often searches for sales online and buys things together with friends to cut down on costs.Cao once wanted to buy an electromagnetic oven  ,which was on sale at a shopping website.He then asked five dormitory roommates to pitch in for the oven.Each student only paid 25 yuan. Most students find it difficult to deal with the expense of accommodation while traveling.So they choose to travel to cities where they have friends and live in their dorms.For instance,Ge Rui,a student at the Hebei University of Technology,has been to many cities where he has friends."Friends can act as free guides,offer me free accommodation,give me valuable tour information,and broaden my mind at the same time," he said.He also had friends from other cities coming over and living with him when they visited his city. Question: What does the writer mainly tell us? Yes or no, is the answer "The ways of saving money on campus."?

Article: Claude and Louris are "giraffes". So are police officers Hankins and Pearson. These men and women don't look like giraffes; they look like you and me. Then, why do people call them "giraffes"? A giraffe, they say, is an animal that sticks its neck out, can see places far away and has a large heart. It lives a quiet life and moves about in an easy and beautiful way. In the same way, a "giraffe" can be a person who likes to "stick his or her neck out" for other people, always watches for future happenings, has a warm heart for people around, and at the same time lives a quiet and beautiful life himself or herself. "The Giraffe Project" is a 10-year-old group which finds and honors "giraffes" in the US and in the world. The group wants to teach people to do something to build a better world. The group members believe that a person shouldn't draw his or her head back; instead, they tell people to "stick their neck out" and help others. Claude and Louris, Hankins and Pearson are only a few of the nearly 1,000 "giraffes" that the group found and honored. Claude and Louris were getting old and they left their work with some money that they saved for future use. One day, however, they saw a homeless man looking for a place to keep warm and they decided that they should "stick their neck out" and give him some help. Today, they lived in Friends' House, where they invite twelve homeless people to stay every night. Police officers Hankins and Pearson work in a large city. They see crimes every day and their work is sometimes dangerous. They work hard for their money. However, these two men put their savings together and even borrowed money to start an educational center to teach young people in a poor part of the city. Hankins and Pearson are certainly "giraffes". Question: "The Giraffe Project" is a group   _  . Yes or no, is the answer "which appeared ten years ago"?

Article: 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.

Question: The first issue Obama will focus his attention on may probably be to   _  . Yes or no, is the answer "deal with the problems of economy"?
