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.

Article: A few years ago I was shopping with a friend and his 12-year-old daughter in downtown San Francisco.A street musician,whom my friend happened to know from his own musician day,was playing the saxophone on a street corner.His name was Clifford,and he had attracted a large crowd with his performance.After he finished,my friend introduced him to me and his daughter.Clifford asked her if she played any instrument.When she replied that she was taking trumpet lessons and played in her junior high school band,he said,"That's fine,little lady.Learn your instrument well and you can play anything."Somehow these simple yet wise words struck me as suitable not only for a trumpet player but also for a reader.If you learn to read well,you can read anything you want--not just newspapers and magazines,but more difficult material like philosophy,film criticism,military history--whatever interests you as your confidence grows.You would not be limited in any way.If you have the vocabulary -or at least a good dictionary near at hand--you can pick up a book,concentrate on it, and make sense of the writer's words. In the United States,reading instruction often ends at elementary school,so students sometimes have difficulty as they progress through school.They must take their assignments,armed only with their elementary,school reading skills.The result,too often,is frustration and loss of confidence.And the assigned reading in your college courses will be even greater than they were in high school.Developing Reading Skills is designed to accomplish several tasks:to show you the skills that will enable you to read with greater comprehension,to help you deal with reading assignment with confidence,and to teach you to become an active reader.
Answer: the connection between playing instruments and reading
The talk between the girl and Clifford serves as an introduction to _ .
