近来,各门学科的学者都十分注意合理需要及其形成的途径问题。这也是可以理解的,因为需要和兴趣是人的行为的基础,是人的积极性和活动的内在动力。 Recently, scholars from all disciplines have paid great attention to the reasonable needs and the ways in which they are formed. This is also understandable, since needs and interests are the basis of human behavior and are the motivation of human beings and the intrinsic motivation of activities.
