Only 27 years old, the Chinese pianist Lang Lang has become an inspiration to tens of millions around the world. Among his dazzling long list of titles, Lang considered UNICEF goodwill ambassador the most special one. "Being a UNICEF goodwill ambassador is the best decision I have made and will definitely be the best experience in my life," Lang said in a recent interview with Xinhua at the UN headquarters in New York. "I love children very much, and playing piano for them is my favorite," Lang said, beaming with delight. Named this year by Time magazine as one of the 100 World's Most Influential People, the pianist said he hoped music could "bring children happiness and enlighten their life." Three months after his nomination , Lang went to Tanzania with the UNICEF team to visit children threatened by malaria and AIDS. Although the southeastern African country's underdevelopment and harsh living conditions surprised Lang who landed the continent for the first time, he was touched by local children's passion for music. "Most of the kids had never seen a piano before," Lang said. "When I played Chopin's nocturne or waltz to them, those who were too shy to talk to me suddenly became active and began to share with me about their dreams. How amazing it is!" "Music can bring hopes to the kids and open their mind," he said. Following his visit to Africa, Lang began to organize fundraising concerts for children. Now it has become his routine to do 15 to 20 fundraising concerts every year. Except for his efforts on fundraising, Lang also established his own international music foundation last year to assist young talents to play piano. So far Lang has chosen five children from the United States and Germany, providing them with scholarships and opportunities to perform at world-class music halls, he said. In December, he will start the selection in China where he would like to "focus more on physically challenged kids, like blind kids." Question: Why did Lang Lang go to Africa 3 months after his nomination? Options: A: To finish his plan of global performance. B: To experience the local music there C: To help those children facing serious diseases. D: To create new music of different styles.

Read the article and select the best answer. Article: The rise in smartphones among young people may be having a direct effect on how successful they become as adults. Research from the University of Nebraska-Lincoln has discovered the average university student checks their phones 11 times per lesson, and more than 80 percent believe this tech addiction is interfering with their learning. A quarter of students across five U.S states also blamed poor grades in exams specifically on the fact they used mobile devices when they should have been concentrating and revising - and these grades could determine the jobs they end up going into. Barney McCoy, an associate professor of broadcasting at the university, surveyed 777 students at six universities across five states about how they used digital devices in the classroom. The students were from UNL and the University of Nebraska at Omaha in Nebraska, Morningside College in Iowa, the University of North Carolina, the University of Kansas and the University of Mississippi. Around two thirds said they used phones, tablets and laptops for "non-classroom purposes" up to ten times during a typical university day, while 15 percent admitted this figure was closer to 30 times. Among the top reasons why students checked their devices so regularly were staying connected and fighting boredom, at 55 percent. Less than half said the devices were used for classwork. Texting was the most popular distraction technique at 86 percent, while 68 percent said they used their phones to check personal emails. Two thirds used social networks, 38 percent surfed the web and eight percent admitted to playing games when they should have been studying. Despite eight out of ten students admitting their devices were distracting, fewer than five percent considered it to be a "very big" distraction. "I don't think students necessarily think it's a big problem," said McCoy said. "They think it's part of their lives." "It's become automatic behavior on the part of so many people - they do it without even thinking about it." He continued, "They've...
