A recent phenomenon in the choice of careers on the part of the college graduates is the increasing trend towards big companies. Few are interested in research fields. This is an unavoidable problem in a materialistic society，where tempting salaries and fringe benefits are offered by big companies to compete with each other to recruit students before they have completed their studies．On the other hand，as many big enterprises and even government departments tend to concentrate on immediate economic results and show comparatively little interest in long range research，there is a steady shift of scientists and researchers from the pure research to the applied field，where there are more jobs available with better salaries．All this has not only seriously influenced young people’s view on the choice of careers，but on education as well．Many college teachers deplore that fewer and fewer students these days acquire knowledge．
