Article: Once Dr. Mellinkoff invited me to join him at the hospital to discuss interesting cases(, ) with his students.The case at hand was a Guatemalan man, aged 34, who had a fever and many other medical problems.His condition was not improving, and there was not much hope he would live. Dr.: Mellinkoff asked to see the patient.He introduced himself in Spanish and, in a very gentle voice, asked how he felt.The patient smiled and said everything was all right.Then the doctor asked if he was able to eat.The patient said that he had no desire to eat. "Are you getting food you like?" The patient said nothing. "Do you get the kind of food you have at home?" The answer was no. The doctor put his hand on the man's shoulder and his voice was very soft. "If you had food that you liked, would you eat it?" "Yes, yes," the patient said. The change in the patient's appearance couldn't have been more obvious.Nothing was said, but it was easy to tell that a message had been sent and had also been received. Later, the doctor asked why the Guatemalan man wasn't getting food he could eat.One of the students said, "We all know how difficult it is to get the kitchen to make special meals." "Suppose," the doctor replied, "you felt a certain medicine was absolutely necessary but that our hospital didn't carry it, would you accept defeat or would you insist the hospital meet your request?" "I would probably insist," the student said. "Very well," the doctor said."You might want to try the same method in the kitchen.It won't be-easy, but I can help you.Meanwhile, let's get some food inside this man as fast as possible, and stay with it.Or he'll be killed by hunger.By the way, there must be someone among you who can speak Spanish.If we want to make real progress, we need to be able to talk with him." Three weeks later.Doctor Mellinkoff told me that the Guatemalan man had left the hospital under his own power.It takes more than medicine to help sick people; you also have to talk to them and make them comfortable.

Article: Argentina's Lionel Messi has won the Golden Ball awarded to the European Footballer of the Year, becoming the sixth Barcelona player to take the award and the first since Brazilian Ronaldinho in 2005. Messi beat last year's winner Cristiano Ronaldo into second place while Barcelona midfielder Xavi Hernandez finished third in the poll results released by France Football magazine early Tuesday. Praised by Argentina great Diego Maradona as his successor, Messi won an unprecedented treble in Spain last season with Barcelona as the Catalan side swept the Champions League, the Spanish title and the Copa del Rey. The 22-year-old Messi, the first Argentine to win the world-famous award, was the top scorer in last year's Champions League with nine goals, including his superb header in the 2-0 victory over Manchester United in the final. Messi, who scored 473 of a possible 480 points, largely controlled the voting and won with a record-margin of 240 points. Real Madrid winger Ronaldo had 233 and Xavi had 170. "Honestly, I knew that I was among the favorites because Barcelona had a fruitful year in 2009," Messi was quoted as saying by the magazine. " _ The Golden Ball is very important to me. All the players who won it were great players, and some great players never won it." Barcelona had three players in the Top 5 with Andres Iniesta taking fourth ahead of former Barca player Samuel Eto'o. In an outstanding season, Messi netted(...) 38 goals in 51 games in all competitions, often leaving defenders in his wake(...) with a combination of speed, extraordinary abilities and his effective left-footed strike. Messi, who led Argentina to next year's World Cup in South Africa, recently signed a new contract with Barcelona through 2016. Messi had a good start to this season - already scoring nine goals - and put on a great display to help his club defeat archrival Real Madrid 1-0 last Sunday. "It won't be easy to confirm after a year like the one we just went through," Messi said. "I hope the next one will reach the same standards. But to win the Golden Ball two years in a row is not an easy thing." (Read by Guanny Liu. Guanny Liu is a multimedia journalist at the China Daily Web site.)

Article: Bullied kids face a high risk of mental health problems as teens and as young adults. Indeed, kids troubled by bullying may be worse off than those who had suffered physical abuse or neglect, as the study found. Until recently, most studies of child victims focused not on bullying but on maltreatment , Dieter Wolke says. Maltreatment includes physical or emotional abuse, neglect or other behaviors that can harm a child. Wolke's team wanted to better understand bullying's long-term effects compared to those due to maltreatment. They focused on 4,026 children in the United Kingdom and 1,420 more in the United States. Information about bullying and maltreatment was collected for American children to age 13. They collected the same information for British youth up to age 16. The researchers also gathered data on each individiial's mental health as a young adult. Among the Americans, 36 percent of bullied kids had mental problems later. Those problems included anxiety, which is a state of excessive worry. They also included depression. That is a feeling of hopelessness that can last a long time. Among kids who had been maltreated by adults, 17 percent later suffered mental health problems. That was less than half the rate seen in people who had been bullied as school kids. In the U.K. group, the difference was less dramatic. Roughly 25 percent of the bullied kids reported mental health problems later, compared with about 17 percent who had been maltreated. But however you look at it, the findings are disturbing. And that's why Wolke says schools,health services and other agencies must work together to end bullying. Studies like this are important, says C.orinna Jenkins Tucker. They bring attention to the lasting impacts of bullying. Tucker does, however, question the value of comparing bullying to other types of abuse. Such an approach can make it seem like one type of bad experience is worse than the other, she says. In fact, both types have short-term and long-term effects on health. She'd like to see researchers study the big picture. They should try to understand how all ofthese negative experiences together shape children--and sometimes harm them.
Question: It can be inferred from the passage that_.
Options: (A) researchers should pay less attention to maltreatment (B) more bullied kids have mental problems in the USA (C) a similar number of children are maltrcated in America and Britain (D) either bullying or maltreatment has negative effects on chilciren's health
