Example Input: Article: ,. Three-year-old Teddy Lasry was sleeping in his cowboy outfit yesterday at his family's Fifth Ave.apartment when he shot up in bed screaming.A 3-foot-long black-and-white snake twisted around his left arm and had just bitten his little finger. "The babysitter (a person taking care of children while their parents are away for a short time) was frightened to death," said Teddy's father, David Lasry, who, along with his wife, Evelyn, was at work when the snake appeared about 4:00 pm. The horrified babysitter called 911 and the building's doorman.The doorman and two cable TV workers helped take the snake off the boy's arm and put it in a garbage bag.Police rushed Teddy to Mount Sinai Medical Center, where he spent two hours attached to a heart monitor as a precaution in case the snake was poisonous.It wasn't.Experts at the snakebite treatment center at Jacobi Medical Center in the Bronx, where policemen took the snake, found out it was a non-poisonous California king snake. But how did it end up in Teddy's bed? A little detective work determined that the snake had escaped two weeks ago from its cage in the apartment of a doctor whose family lives four floors below the Lasrys.The apologetic owner said his son's pet snake likely traveled up the water pipes and into his neighbor's apartment."It's a very gentle, very harmless snake," he said."It's handled by our family all the time." David Lasry believed the pet was simply hungry after two weeks of wandering.Evelyn said her son seems to have overcome his fright by thinking of himself as a hero cowboy as he rode in the back of the police car to the hospital. "I told Teddy he's a pretty snake, a nice pet snake who got out of his cage," Evelyn said."But he asked, 'Why did he bite my finger, Mamma?' And I said, 'Because he saw that you are a big boy, Teddy, in your cowboy outfit and he got scared.'"

Example Input: Article: People like to look in the mirror often when they have a young and beautiful face. However, when one grows old, nobody wants to see their wrinkled old face in the mirror any more. So, many old people seldom look at their faces in the mirror. This is completely wrong. According to Wu Zhenyun, a professor from the Psychological Research Institute under the Chinese Academy of Sciences, a person's willingness to look in the mirror can reflect his or her mentality. When people don't care too much about their age, they will try to carry themselves with ease and natural poise . They don't mind looking in the mirror to see their own faces. Some people even love to look in the mirror from time to time to see whether they keep a good appearance. In this way, mirror becomes their best friend that help them to look confident. On the other hand, some people are afraid of being old. They don't want to see the wrinkles on their face and their hair turning grey. So they don't want to look in the mirror. This actually reflects a negative attitude they hold towards life. In the long term, they might suffer from psychological pressure or some sort of depression, which is actually not a wise act. " Everyone can make themselves look charming at every age stage. If one is confident, one will always look beautiful, it shows that they accept themselves." professor Wu said. Mirror cannot only give confidence to one. By looking in the mirror, one can even find the traces of some diseases from one's own face.

Example Input: Article: Eleven top universities are joining the Open University to launch free Internet courses. King's College London, along with the Universities of Birmingham, Bristol, Cardiff, East Anglia, Exeter, Lancaster, Leeds, Southampton, St Andrews and Warwick, has partnered with FutureLearn, a company set up by the Open University that will offer free and non-credit bearing courses to Internet-users around the world. The courses are modeled on the US phenomenon "Massive open online courses" ( Moocs ), which have attracted millions of users around the world and are especially popular in emerging economies. FutureLearn will improve UK institutions for international students, said Prof Martin Bean, voice-chancellor of the Open University. "At the moment, foreign students' _ of UK Universities is: wonderful history, great tradition, really good teaching, but a bit boring." Leeds University says the partnership will benefit students studying on campus. "Students will have access to a rich set of resources from both Leeds and our partners. They can also broaden their education beyond their main subject areas." The UK higher education industry stands among the top five export earners for Britain Moocs have grown rapidly in the US over the past year, with two providers leading the field. Coursera offers courses from 33 Universities, including Princeton, Brown, Columbia and Duke, and has reached more than 1.7 million users, EdX, a nonprofit start-up from Harvard and the Massachusetts Institute of Technology courses this autumn. Simon Nelson, one of the key architects of BBC Online, will head FutureLearn as launch CEO. "It's really meaningful for these universities to come together -we'll punch much harder collectively than any other university will individually," he said. Partner Institutions will be responsible for their own content while the OU, which has been providing distance-learning courses since 1971, will assist with course delivery and infrastructure. Details of further universities will be revealed next year, as will the courses on offer.
