王淦生 《中学政治教学参考》2011,(16)
只有民族的,才是世界的。古城西安以她的存在向世人诠释着这则名言的精辟。随便问起一个西安之外的人对西安的了解,可能都会说出一连串的名词:兵马俑,大雁塔;秦汉故都,大唐宫阙……这些使西安城享誉世界,成为世界四大古都之一。可是,将这些荣耀的冠冕加在今人的头上,总会觉着一丝惶恐与不安,因为这些毕竟是萦绕在先人头上的光环。而在我的印象中,若将黄土高原上的长安城与北京、上海、广州这些东部大都市相比,总觉得她的身上或多或少带着几分土气和一丝暮气。 相似文献

住宿生是典型高中生的标本,我对高中的印象也主要源于宿舍。我的宿舍实在“别致”,红校园里矗然一幢有如脏面包发霉的灰楼,初见本以为是校建仓库,后来却一记晴天霹雳——我得在这“仓库”里住上三年。 相似文献

在学习反函数这一节时,教材(人教版第一册上)用这样一句话概括原函数的图象与反函数的图象的关系:一般的,函数y=f(x)的图象和它的反函数y=f^-1(x)的图象关于直线y=x对称.对于这句话很多同学有着错误的理解,而且在一些参考资料中也时常见到:如果原函数的图象与其反函数的图象有交点,则交点必在直线y=x上. 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

The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 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
