A business man that I admire Jack Ma is a man of such a tragic early job-hunting experience, as II out of 12 men were hired by Mcdonald's, and he was the only person who was rejected 20 years ago. However, today he was called halfjokingly by netizen, The DADDY JACK, since he has became the richest people in china. He once said tonight is fierce, tomorrow night will be more intense, but many people died in the night of tomorrow, and fail to see the sweet sunrise of the day after tomorrow. Theses words inspired me to persist and never give up. He is the only business man I admire.

Will teachers be replaced by the Internet With the advent of information highway, it is easy for people to acquire knowledge via Internet, and poeple end up believing that teacher as a occupation would exticnct in the rencent future. However, I respectfully disagree. The fuctions of teachers are not merely offering information. The teacher is a devine profession for pupils. Although all kinds of information taught in class is available on the Internet, but we still need a guide for our class. Take law school student for example, all the cases discussed in seminars are available on certain website, but it is almost impossible for law school student to learn anything. The existance of a teacher, largely reduce the amount of time you spend on your study, because they are so experienced that can effortlessly guide you to find the easiest way to learn. Teachers are not only responsible for delivering knowledge, but also for cultivating all kinds of ablities and developing a variety of personality traits. The main purpose of education exist in making student prepared for further social life. The experience you have learnt through teamwork in class, under the guidance of your teacher, would definately be a treasure when hunting job in the future, which merely relying on the Internet would hardly require. And most youngsters who stray from their life, are less educated. The abscence of guidance from teachers make them vulnerable to the influence imposed by gangsters. Although Information highway has brought convience to our academic life, we can acquire a certain amout of knowledge through the Internet. However, teachers play a critical role in the formation of personality traits abd providing useful guidance in your life. So, teachers are unplaceable for youngsters.
