C My name is A. J. Hoge. I am the creator of the Effortless English Teaching System and I am the Founder and Director of The Effortless English Club——one of the most popular English learning systems in the world. My audio lessons are best－sellers in over 25 countries and my radio podcast (播客)has over one million listeners worldwide. I am also the publisher of the Effortless English Online Newsletter, which has over half a million subscribers(用户) (and growing every day). I am a leading expert on topics related to English speaking success and teaching mastery. I created the Effortless English Teaching System after many years of teaching English in universities. My former students include business professionals, scientists, teachers, professors, graduate students, and many other successful adult English learners. These students were just like you. They were frustrated English learners who could not speak well. Using the Effortless English system, they learned to speak English easily and automatically. Each of these students made incredible improvements in a very short time. You also will improve quickly when you use the entire Effortless English System. The Effortless English System is designed for you——the independent adult learner. Effortless English focuses exclusively on speaking and listening skills. The system is designed to improve your speaking power as quickly as possible——using proven and tested methods. When you follow the entire system every day for 6 months, your speaking becomes much faster and easier. Your spoken grammar improves powerfully——yet you will never study grammar rules in this system. Your pronunciation improves powerfully——yet you will not focus on pronunciation. 49．What's the author's purpose of writing this text? A．To introduce himself.
