题目内容：
Teaching is supposed to be a professional activity requiring long and complicated training as well as official certification(证明). The act of teaching is looked upon as a flow of knowledge from a higher source to an empty container. The student' s role is one of receiving information ； the teacher's role is one of sending it. There is a clear distinction(区别) assumed between one who is sup-posed to know ( and therefore not capable of being wrong) and another, usually younger person who is supposed not to know. However, teaching need not be the province(领域) of a special group of people nor need it be looked upon as a technical skill. Teaching can be more like guiding and assisting than forcing information into a supposedly(假定地 empty head. If you have a certain skill you should be able to share with someone else or to help them in their attempt to teach themselves．All of us, from the very youngest children to the oldest members of our cultures should come to realize our own potential as teachers. We can share what we know, however little it might be, with someone who has need of that knowledge or skill.
