填空题 Translate the following passage into Chinese．Write your translation on the ANSWER SHEET．(中山大学2011研，考试科目：基础英语)The period of Chinese scientific activity did not begin until the first years of the Republic. The older reformers only introduced a book knowledge of the sciences, without fully understanding their intellectual significance, without adequate equipment for laboratory work, and without adequately trained leaders to organize the studies and researches. Most of the textbooks on science were translated by men who admired science most sincerely but who had only a very superficial book knowledge of the subjects in the Japanese schools, and never did real laboratory work or undertook field expeditions. The schools were beginning to have classroom experiments in physics and chemistry, and botanical and zoological specimens: but they were as bookish as the textbooks, and were useless for the training of scientific workers.
