化学，这是个我们每天要在教科书上看上无数遍熟悉的词语，作为一个中学生，这也是我们必须刻苦学习的一科，在平日的学习里，有些同学总觉得化学离我们太过遥远，其实不然，在我们生活的各个方面，社会发展的各种需要都与化学息息相关。

事实上，起源于19世纪、发展完善于20世纪的化学合成技术，应该说是20世纪人类在科学技术发现、发明方面最伟大的成就。可以这么说，没有正在高速发展的信息技术，人类还不至于无法生存，而没有上世纪的化学合成技术，人类真的将会落入食不果腹、衣不蔽体、有病无药的尴尬境地。所以，从这个意义上讲，化学学科的发展与人类的生存、生存品质的改善都是密切相关的。

一个没有化学的世界将没有合成材料,这意味着没有电话,没有电脑,没有 电影院,没有合成布料.那也将是一个没有阿司匹林,肥皂,洗发水,牙膏,没有 化妆品,避孕药,纸张(因此也就没有报纸和书籍),没有胶水和油漆的世界. 我们必须仔细记住化学帮助艺术史家深入探究博物馆油画和雕塑背后的秘密;它帮助法医学家分析从犯罪现场获得 的样本,以便迅速追踪罪犯;它还揭示了菜肴迷住味蕾的分子基础. 正如物理破译宇宙的规则,生物学解 密生物世界,化学是关于物质及其变换的科学.

化学对我们有着举足轻重的作用,不仅因为其在整个自然科学知识体系中占据着重要地位,而且它对经济具有特别重要的作用,并在我们的日常生活中无所不在.但是,正因为其无所不在,我们常常忘记它的存在,甚至根本不提到它化学，不会自我炫耀,但没有它,一些真正令人瞩目的成就不可能达成,如治疗疾病上的突破,太空探索和技术奇迹等.它在食品和药品,衣服和住房,能源和原材料,交通和通讯等各方面为人类作出了极其重要的贡献.它为物理和工业提供材料,为生物学和药理学提供模型和基质,为科学和技术提供属性和程序。

人们过多地将化学与环境污染、恐怖威胁、化学武器等联系起来，化学给人类带来的似乎只有这些东西。在我国，人们甚至将近年出现的三聚氰胺奶、吊白块、假鸡蛋、假化肥、假农药等重大掺杂使假事件也要归罪到化学工作者的头上。

很少有人认识到，人类赖以生存的基本粮食蔬菜供应1/3源自化学肥料和化学农药的使用。考虑到当今粮食蔬菜供求基本平衡这一事实，如果没有公

众“憎恨”的化肥、农药的使用，地球将只能承载世界现有2/3的人口，或者说，我们的人均食品蔬菜摄入量将减少1/3，不难想象，那将是一个多么动乱不堪、弱肉强食的恐怖世界！同样，没有化学就没有使人类疾病得以治疗的合成药物，人类的平均寿命起码要减少一半。化学的发展，使合成纤维占据了纤维市场的半壁江山。可以毫不夸张地讲，没有化学，就没有温暖，世界也没有视觉上的丰富多彩。

人类社会发展到今天，正面临资源日渐枯竭、能源供应日渐不足、环境品质日渐蜕变等前所未有的困难，在解决人类社会发展面临的这些根本性问题过程中，任何学科都无法替代化学学科的作用。迎接发展中的挑战和机遇，化学是无可替代、大有可为的。无可替代，是指化学的角色舍我其谁；大有可为，是说化学的发展前景非常广阔。我们有充分理由相信，化学的明天一定会更加美好。

第二篇：中国高等教育国际化的必然趋势 英语演讲

An inevitable trend of internationalization of higher

education in China

The economic basis of society, education depend on the survival and development of the condition. When the economic

globalization has become a reality with the inevitable, education, globalization and internationalization of higher education to become a trend. How the higher education in China in the international trend toward powerful, from four

points of view

First, the development of scientific development strategy and

planning

International higher education, to fight and expanding the right to speak. The relationship between internationalization and localization, the introduction of output as well as short-term response and long-term development. Essentially, the internationalization of higher education should be a national cultural equality, a two-way process of integration, rather than pan-world process of a culture of a country. As long as we grasp and make good use of the international trends, a countries culture and education both independent of each other, with different features and influence each other, merging the new situation of the development of higher education in the

world is bound to come.

Build international training objectives and curriculum system The internationalization of higher education is an important

goal is to strive to cultivate international awareness, international exchanges and international competitiveness of the compound talents. Under the guidance of the concept of international adjustment and optimization of the existing course structure, phase out outdated curriculum to increase

the courses with international content.

Third, all-round, multi-level and wide-ranging, two-way,

multi-directional interaction

With an open mind and a three-dimensional means of international cooperation. International co-operation in scientific research, technical assistance cooperation of international students, international promotion of Chinese

culture, we are promising.

Clear educational positioned to achieve the transformation of

the seller's market to a buyer's market.

Education and opening up of China is bound to bring fierce competition among institutions of higher education to change the traditional concepts of education, a clear positioning itself for higher education The identity of the provider of educational

services, to participate in international competition in the domestic education market. The emphasis on market-oriented, practical teaching plans to be adjusted as the market changes in the specific courses. And integration of high-quality foreign educational resources through international exchanges and cooperation, and continuously improve the quality of education, enhance students' employability and competitiveness, thereby enhancing the competitiveness of the College in the education

market.

In the face of the rapid development of the global economy, the internationalization of higher education in China becomes more and more important. Efforts to stimulate students' interest in the implementation of the research study, to break through the traditional teacher-student interaction mode. As a graduate student, we should strive to enrich their knowledge, more exposure to international education courses, watch some prestigious universities open courses online, to enrich our

horizons, to do a good job fully prepared for the

internationalization of higher education in China also fully prepared for the future development of our life well. Train themselves into a solid foundation, wide knowledge, ability,

high-quality talent.
