在为“三农”服务工作中 ,目前国家、省、市等各级有关部门都在搞卫生、文化、科技的“三下乡”活动。送医送药的卫生下乡与发行图书、演出节目的文化下乡都是广大农民可以直接受益的。而在科技下乡活动中 ,由于传授者与被传授者之间存在着文化层次的差距 ,农民不能立即受益。? In serving the “agriculture, rural areas and farmers”, the relevant departments at various levels at the national, provincial and municipal levels are engaging in the “three rural areas” activities of health, culture and science and technology. Health delivery of medicine to the countryside and distribution of books, cultural performances of the show are the vast majority of farmers can directly benefit. In the countryside activities of science and technology, farmers can not benefit immediately because of the cultural differences between the educators and the educated people. ?
