We_should_do_the_following_right_things:_drink_boiled_water,_wash_our_hands_in_a_right_way,_cook_raw_food_thoroughly,_heat_the_food_left_overnight,_deal_with_the_rubbish_in_time,_wear_a_mask_whenever_necessary,_and_so_on. |阅|读|技|能|提|升| 本文的语篇类型为叙事记叙文。这类记叙文多以时间顺序或空间顺序来行文。本文属于以时间顺序展开的叙事性记叙文，其暗线是科学家John Snow战胜霍乱病毒的科学研究步骤。读文时可以按照事件发展的开始、中间和结尾三个阶段来理清事件的行文顺序。本文第一段介绍了研究的背景；第二段则是提出问题和假设；第三段是研究过程；第四段是得出结论；第五段指出，John Snow的研究方法对科学家们研究疾病具有指导意义。 (一)赏用词之妙　 1．However, he never lost his desire to destroy cholera once and for all. 赏析：句中的否定副词never加强了句子的语气， 反映了John Snow的坚毅品格和执着精神。其他起突出和强调作用的否定副词(短语)还有：not, no, none, nobody, nothing, neither ...nor, nowhere等。 2．Snow suspected that the water pump was to blame.What is more, in another part of London, a woman and her daughter had died of cholera after moving away from Broad Street. 赏析：句中What is more意为“而且； 更重要的是”，它与前一句是递进关系。作为常用的过渡语，它能很好地推动叙事或故事情节的发展。在本句中，它的使用也表明了John Snow研究的科学严谨性。 提能训练/翻译句子 ①他从未错过任何一个变得更强的机会。 He_has_never_missed_a_single_chance_to_become_stronger. ②更重要的是，一些中国著名音乐家将为我们演出。 What's_more,_some_famous_Chinese_musicians_will_give_us_performances. (二)赏句式之高　 1．It seemed that the woman liked the water from the pump so much that she had it delivered to her house every day. 赏析：句中使用了嵌套式从句，主句使用了“it seemed that ...”式的主语从句，从句中又使用了“so ...that ...”式的结果状语从句。这种嵌套式从句使叙述更加简洁，表意更加精准。 2．The people who drank this water were much more likely to get cholera than those who drank pure or boiled water. 赏析：本句使用了嵌套式从句，主从句中都包含了who引导的定语从句，它们分别修饰先行词The people和those。本句简洁明晰地表明了John Snow的调查结果。 提能训练 ①(句式转换)Seemingly, some students would like to start work early and thus they can help offer their parents better lives.(用嵌套式从句改写) →It_seems_that some students would like to start work so_early_that they can help offer their parents better lives. ②(完成句子)Scientific study shows people who_got_enough_sleep before taking a math test did better than those_who_stayed_up_all_night_studying. 科学研究表明，在数学考试前获得充足睡眠的人比那些通宵学习的人表现得更好。 (三)赏衔接之顺　 1．Snow began by marking on a map ...However, ...What is more, ...Accordingly, ... 赏析：文中第三段是John Snow的调查过程，该段使用了“however, what is more, accordingly”等句间衔接语，它们使叙述更有逻辑性，层次更加清晰。 2．Through Snow's tireless efforts, ...However, ...Moreover, ...For this reason, .... 赏析：文中最后一段是调查结果与John Snow取得的成就，该段使用了“however, moreover, for this reason”等句间衔接语，它们使表达富有逻辑，衔接紧密，意思连贯。 (四)赏结尾之翘　 Moreover, in his use of maps and statistics, Snow transformed the way scientists study diseases.For this reason, Snow is considered the father of modern epidemiology. 赏析：此处是文章的结尾部分，这两句概括了科学家John Snow的伟大成就。叙事记叙文的结尾大都是对人物的成就进行概括性评价。这种方法也可以用于介绍人物的应用文写作。 He was very diligent and also believed that ①genius_is_one_percent_inspiration (天才是百分之一的灵感) and ninety­nine percent perspiration.All these explained ②why_he_had_so_many_great_inventions_and_what_he_did_inspires_me_to_be_creative_in_my_work (为什么他有这么多伟大的发明，并且他所做的一切激励着我在工作中发挥创造力)． 科学无国界。我国老一辈科学家从国外学成归来，为新中国的崛起勤奋工作，无私奉献，奋斗不止。他们的事迹可歌可泣、感人至深。其中我国光学之父——王大珩就是一位杰出的代表。现在就让我们一起来看看他的感人事迹和对我国光学事业作出的巨大贡献吧！ Wang Daheng, the Father of Chinese Optics (光学) In 1949, the field of applied optical science didn't exist in China.Understanding its importance for national strength, the Chinese government paid much attention to optical research. Wang Daheng, a respected optical physicist, devoted his whole life to this cause.He kept watching on the development of China's first piece of optical glass, first electronic microscope, first laser device, and first large­size optical measuring equipment, and helped to found the Chinese Academy of Engineering.He is called the Father of Chinese Optics. As a teenager, Wang Daheng often followed his father to the observatory and became greatly interested in the apparatus (仪器) there.In 1936, he graduated from Tsinghua University with a degree in physics.Two years later, he won a government scholarship to study in England.After earning his master's degree from Imperial College London in 1940, he began his doctoral studies in optical physics and technology. In 1948, Wang gave up his established career and comfortable life in the West and returned to his motherland with the aim of empowering (增加自主权) it through science and technology.At the time China did not have the capability to produce optical measuring equipment on its own.In 1951, Wang was instructed to found an institute of fine mechanics and was appointed its first president.Within less than two years, Wang and his team produced the first group of China­made optical glass.Over the following six years, they went on to develop the country's first electronic microscope, first high­precision theodolite (经纬仪), first optical rangefinder, and five other optical devices, laying the foundation for China's precise optical instrument industry.In 1961, they independently developed the ruby laser in China.In addition to scientific research, Wang advanced the study of optics in higher education. nuclear bombs, missiles, and man­made satellites.In 1970, China successfully launched the When the satellite returned to Earth, the devices they designed brought back clear images of our home planet as seen from outer space for the first time. To close the technological gap between China and developed countries, Wang and three other scientists made the suggestion of drawing up a national hi­tech research and development plan in 1986, which led to the famous 863 Program. In 1992, Wang and a group of other scientists called for the creation of the Chinese Academy of Engineering.In the following years, he won many honors from the state.He passed away in Beijing aged 96 on July 21, 2011 after living a full and fruitful life.
