Most of you graduating today will be employees all your working life, working for somebody else and for a paycheck. And so will most,【21】not all, of the thousands of other young Americans graduating this year in all the other schools and colleges across the country. 【22】has become a society of employees. A hundred years or so ago only one【23】every five Americans all work was employed, i.e. , worked for somebody else. Today only 20% of Americans are not employed but working for themselves. And【24】fifty years ago 'being employed' meant【25】as a factory laborer or as a farm hand, the employee of today is increasingly a middle-class person with a【26】formal education, holding a professional or management job requiring【27】and technical skills.【28】, two things have characterized American society during these last fifty years: the middle and upper classes have become employees and middle-class and【29】employees have been the fastest growing groups in our working population-growing so fast that the industrial worker, that【30】child of the Industrial Revolution, has been losing in numerical importance【31】the expansion of industrial production. This is one of the most profound social changes any country【32】. It is, however, a perhaps【33】greater change for the individual young man【34】to start. Whatever he does, in all【35】, he will do it as an employee wherever he aims, he Will have to try to reach it【36】being an employee. As an employee you work with and through other people. This means that your success as an employee will【37】on your ability to communicate with people and to present your own thoughts and ideas to them【38】they will both understand what you are driving【39】and be persuaded. The letter, the report or memorandum (记录) the【40】spoken 'presentation' to a committee are basic tools of the employee. (41)
