  大約三百年前,玛丽·沃特利·蒙塔古夫人给她的女儿接种了天花疫苗,使她的孩子成为西方第一个得到疫苗保护的人。她的一系列付出为疫苗的应用及推广铺平了道路。
  1 About three hundred years ago, Lady Mary Wortley Montagu got her daughter inoculated (接种) against smallpox (天花), making her child the first person in the West to be protected in this way. Without Montagus willingness to adopt a practice she had learned from other cultures, the introduction of vaccines would never have taken place.
  2 Montagu first witnessed inoculation when she accompanied her husband to Turkey in 1717. Inoculation had started in Asia, probably in China, as early as the 10th century AD. Montagu observed how older women in Turkey took a tiny amount of pus (脓) from a person with smallpox. They then used needles to make cuts on peoples wrists and ankles and added the pus to their bloodstream. This helped people gain immunity (免疫力) against future infection.
  3 Like other visitors to the country, Montagu took steps to ensure that her son was inoculated in Turkey. This worked well, but she knew that trying it in England would be far more challenging. Inoculation performed by unlicensed amateurs would threaten doctors professional standing and potentially rob them of valuable income. Churchmen also disagree with the practice, as they saw it as going against nature.
  4 Back in England, Montagu observed the increased severity of smallpox infection. Eventually, in April 1721, she decided to use the Turkish practice to have her daughter inoculated, because she believed that the rewards would outweigh the risks. After a safe time had passed following the inoculation, Montagu allowed doctors to examine her daughter.
  5 Doctors in Britain gradually accepted the practice. Years later, a pioneering physician found smallpox vaccines to destroy smallpox completely. As early as last century, academics argued that Montagu was no more than an enthusiastic amateur. In truth, she made a vital scientific contribution towards finding the cure for smallpox.

【摘要】社区教育发展的目标是构建“人人皆学、处处可学、时时能学”的学习型社会。区域文化自觉的程度和社区教育“时间度、空间度、效用度”影响制约着社区教育的发展。文化自觉包含“文化认同、文化需求、文化追寻”三个层次。文化自觉如何与社区教育的“三维”有效地衔接,满足社区居民“职业技能、科学文化、社会生活、休闲娱乐”等需求也成为了当前社区教育发展的新思路。  【关键词】 社区教育;内在契合;文化自觉;教育

我在前不久写的一篇短文中说,信息技术发展及其越来越广泛的应用,为教育变革提供了似乎无穷无尽的想象空间和探索空间。人们往往还没有来得及真正了解已经发生的事,又不得不于匆促间面对新的变化以及随之而来的诸般“纠结”,时常难免有些头晕目眩的感觉。最新的例证,就是近年来迅速兴起的慕课在中国骤然升温,关于慕课的争论也正在不同层面展开,不少人认为,慕课热中特别需要的是冷思考。对于慕课所涉及的许多问题的研究,包括
国家开放大学及北京开放大学、上海开放大学日前揭牌成立,无疑是将载入我国教育发展史册的重要事件。作为国家教育体制改革试点项目,国家开放大学揭牌显然更是“开端”而绝不意味着“终结”。制约开放大学发展的问题不可能“迎刃而解”,许多业内人士已感到来自各方面的压力“陡增”,包括那些以往不同程度被掩盖、被淡化、被搁置的较深层次问题,似乎也有进一步表面化的趋势。正如国务委员刘延东所指出的,“适应新要求,承担新使
