the science and technology demonstrates the formidable strength in the different domain. Electronic industry, communication technology daily popularization, nanotechnology, superconductivity material widespread application, soon one day, perhaps in yours dinner table, can appear likely bio-engineering foods and so on outer space green pepper, man-made beefsteak. Studies the science and technology, is not merely in order to become the scientist, also is for can adapt the life, more has been able to become the new century the master, the load gets up the new century, is the national construction, makes the contribution for the human culture.

If the elders have constructed the 20th century motherlands with the industrious work, that, we should by the knowledge, get up the new century heavy burden by the scientific load.

　　Schoolmates, we are being at the growth developmental stage, the study science, lets us start since childhood. We must learn each kind of literacy class diligently, because this is all study foundation; At the same time, to each kind the popular science books, the publication which suits our elementary student to look, should better
