人们常说,博物馆是人们终生教育的殿堂,也是广大青少年的第二课堂。以宣传辨证唯物主义,普及自然科学知识为宗旨的自然类博物馆,是通过对动物、植物、古生物和天文地理等标本的展示,科学地揭示自然现象,从而启发人们去认识自然,保护自然和利用自然。凸显博物馆为社会和社会发展服务的功能,实现人与自然和谐发展,为构建和谐社会发挥应有的作用。为此,笔者着重从自然类陈列对青少年智力开发的作用、形式和创新方面作粗浅探讨,旨在抛砖引玉,引起同行的更加重视。 相似文献

人们习惯上喜欢追求完美,偏爱平衡和对称.完美是一种简单,也意味着秩序,而自然界看上去似乎也是完美的,也常常能如人所愿.但当人们为发现自然界中某些对称而得意之时,自然却又会露出点瑕疵,它似乎并不总是那么听话.很有可能自然本身就不那么对称、完美,是人们把对称的外衣加到自然身上去的,使自然看上去完美.如果真是这样的话,露点瑕疵也就很正常了.不过,人们要找出自然的规律,不借助对称也很难.也许正是因为这样,自然才一次次地打破人们先前找到的对称. 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献

Today, Sunday morning, I sit thinking and typing at my computer. My thoughts are in my homeland, India and my body is in China. The body is here and mind there for a good reason. Mr. Hu is president and I am resident and both are in each other's countries (what a difference the absence of one small letter makes!). Mr. Hu will return in a few days and I will stay on longer. 相似文献
