论文部分内容阅读
这里选登的三篇地学小论文,都是各省、市、自治区地质学会科普委员会推选上来的优秀作品。作者都是中学生。他们为将来献身祖国地质事业,勇跃加入了各地的青少年地学爱好者协会;积极参加了地学夏令营、地质旅行、地质考察和现场参观;并和老一辈地质学家坐谈、会见……。这些活动,使他们广开眼界,学到了课堂上学不到的知识,很值得提倡和大力开展。他们的小论文不仅是自己学习体会的总结,对广大地学爱好者也很有启发。此外,对培养他们的写作能力,也大有好处。近两年来,各地青少年地学活动开展很活跃。北京市青少年地学爱好者协会去年举行了首届年会,会上从118篇小论文中,评选出29篇获奖作品。今后望各省学会能推荐最佳作品给我们,也希望老师、同学们把地学课中遇到的问题、想法、要求告诉我们。
The three selected essays on earth science selected here are outstanding works selected by the popular science commissions of provinces, municipalities and autonomous regions. The authors are middle school students. They devoted themselves to the geology of the motherland in the future and joined the Association of Young and Middle-Aged Geosciences enthusiasts all over the country. They actively participated in geoscience summer camps, geological trips, geological expeditions and on-site visits. They also held talks with older geologists and met .... These activities enable them to broaden their horizons and learn what they can not learn in the classroom. It is worth promoting and vigorously developing. Their essay is not only a summary of their own learning experience, is also inspired by the majority of geosciences lovers. In addition, it is also good for developing their writing skills. In the past two years, youth geosciences activities around the world have been very active. Beijing Youth Geosciences Association held its first annual meeting last year, from 118 essays, selected 29 winning entries. In the future, I hope all the provinces can recommend the best works to us, and I also hope teachers and students can tell us the questions, ideas and requests that they encounter in the course.
