Example Input: Article: One of the major functions of an iPhone is, of course, to play music. The iTunes app has been designed in such a way as to take advantage of the iPhone's touch screen. But what if you want to listen to music that isn't in your iTunes library, or you want to discover new music without sitting in front of computer? There are plenty of ways to access music, but not everyone knows what options are available. Either that, or there are so many options that going through all of them is tiring. For these reasons, here we offer a few convenient ways of listening to music on your iPhone without using iTunes. Stream some radio (Tuneln Radio) Tunnel Radio provides a quick and easy way to listen thousands of Internet radio stations on your Apple products. In addition to local radio stations, this app compiles more than 40 000 radio stations from around the country. What makes the app special is that it allows you to pause and rewind live radio----pause your station to take a phone call or rewind to replay a favorite song. You can also browse by genre of location, and the app includes plenty of talks, news, sports and weather stations in addition to music. From desktop to smartphone (QQ Music) QQ Music seems like obvious choice, and it is. It's a streaming service based on the Tencent technology that is already wildly popular on the Internet and now also offers a (free) app. Through this app you can listen to existing playlists or create new ones based on the patterns of music you like. It works amazingly well and everything can be saved to your QQ account for access from a computer. What was that song? (Shazam) Shazam is an innovative and free app that cures your"what was that song?"problem. It happens to all of us : we hear a song (on TV or in a store ), love it, know we have heard it before but just can't remember what it is called . With Shazam you don't need to. Just hold your iPhone up and through its microphone, Shazam will identify the album, artist and song title for you. You can then either purchase the song in iTunes or search it on other apps for streaming. How cool is that?

Example Input: Article: I was an introvert by nature. For as long as I remember, showing a sincere smile when meeting someone had never been easy. When meeting people, instead of being excited, I often felt upset or self-disturbed. But we all know having friends is important. The more friends you have, the more opportunities you get, no matter whether it's a job opportunity, a romantic relationship, or a business partner. So a smile is important to making others feel comfortable. Mother Teresa said, "Every time you smile at someone, it is an action of love, a gift to that person and a beautiful thing." The smile I'm talking about is not to make a face to someone. I'm talking about those wide smiles you make when meeting old friends. So I've discovered a trick. I call this technique "Oh, it's Jamie!" When I meet someone, I imagine him as an old friend of mine called Jamie. He was my first friend when we were still kids. It's no secret why my smile is as wide as I can possibly make. And the best part, whenever you're friendly to others, they are friendly in return. You're not hearing this from me. A research which was done early by scientists actually backs this claim. So do remember to give it a try.

Example Input: Article: It was not the first time for Shi Benliang, a senior physics major at Peking University, to feed cats. But the 22-year-old felt sad when he saw the scars and wounds on the bodies of the little creatures. "I can imagine how they have suffered from being abandoned. They lead a harsh life wandering around," said the student..Shi is one of a dozen students at the university volunteering to feed the stray cats during the winter break. Recruited by the Stray Cat Rescue Association at the university through a Bulletin Board System (BBS), he took turns with other students to care for the homeless animals. It is estimated that there are more than 100 stray cats on the campus of Peking University. Jin Jing, 18, an economics freshman at the university, cared for the cats for two days. "At around 5 pm I cycled to the 22 feeding sites on campus marked on a special map," she said. "At each site I left some cat food and water."Jin was excited when the animals rushed to her feet. "Some are shy and timid, and others are more outgoing. Each of them has their own name such as 'Sweet Orange' or 'Karl Marx'," she said. "By feeding them I learned to respect life." Liu Chenhao, a senior electronics and computer science major, who is in charge of the association, said that feeding was just one part of their responsibilities."Our aim is to keep the stray cats in check and maintain harmony between them and the students on campus," he said. The organization also takes cats to the animal hospital to be treated for oral and skin disease. Another of its major tasks is to find new homes for the cats by uploading their photos and information online. "We're very careful when selecting owners and ask them lots of questions to ensure that they won't desert their cat under any circumstances, such as when they move house or get married," Liu said. But he stressed that their acts of kindness shouldn't encourage anyone to abandon their cat. "A cat's normal life expectancy is more than 10 years, but a stray one may survive for only two or three."
