But he became inspired when he tho ught about helping ordinary people exposed to cholera. This was the deadly dise ase of its day. Neither its cause nor its cure was understood. So many thousand s of terrified people died every time there was an outbreak. John Snow wanted t o face the challenge and solve this problem. He knew that cholera would never b e controlled until its cause was found. He became interested in two theories that possibly explained how cholera ki lled people. The first suggested that cholera multiplied in the air. A cloud of dangerous gas floated around until it found its victims. The second suggested that people absorbed this disease into their bodies with their meals. From the stomach the disease quickly attacked the body and soon the affected person die d. John Snow suspected that the second theory was correct but he needed eviden ce. So when another outbreak hit London in 1854, he was ready to begin his enqu iry. As the disease spread quickly through poor neighbourhoods, he began to gat her information. In two particular streets, the cholera outbreak was so severe that more than 500 people died in ten days. He was determined to find out why. First he marked on a map the exact places where all the dead people had liv ed. This gave him a valuable clue about the cause of the disease. Many of the d eaths were near the water pump in Broad Street (especially numbers 16, 37, 38 a nd 40). He also noticed that some houses (such as 20 and 21 Broad Street and 8 and 9 Cambridge Street) had had no deaths. He had not foreseen this, so he made further investigations. He discovered that these people worked in the pub at 7 Cambridge Street. They had been given free beer and so had not drunk the water from the pump. It seemed that the water was to blame. Next, John Snow looked into the source of the water for these two streets. He found that it came from the river polluted by the dirty water from London. H e immediately told the astonished people in Broad Street to remove the handle f rom the pump so that it could not be used. Soon afterwards the disease slowed d own. He had shown that cholera was spread by germs and not in a cloud of gas. In another part of London, he found supporting evidence from two other deat hs that were linked to the Broad Street outbreak. A woman, who had moved away f rom Broad Street, liked the water from the pump so much that she had it deliver ed to her house every day. Both she and her daughter died of cholera after drin king the water. With this extra evidence John Snow was able to announce with ce rtainty that polluted water carried the virus.

-必修 5 Unit 2 The United Kingdom Reading PUZZLES IN GEOGRAPHY People may wonder why different words are used to describe these four countries: England, Wales, Scotland and Northern Ireland. You can clarify this question if you study British history. First there was England. Wales was linked to it in the thirteenth century. Now when people refer to England you find Wales included as well. Next England and Wales were joined to Scotland in the seventeenth century and the name was changed to "Great Britain". Happily this was accomplished without conflict when King James of Scotland became King of England and Wales as well. Finally the English government tried in the early twentieth century to form the United Kingdom by getting Ireland connected in the same peaceful way. However, the southern part of Ireland was unwilling and broke away to form its own government. So only Northern Ireland joined with England, Wales and Scotland to become the United Kingdom and this was shown to the world in a new flag called the Union Jack. To their credit the four countries do work together in some areas (eg, the currency and international relations), but they still have very different institutions. For example, Northern Ireland, England and Scotland have different educational and legal systems as well as different football teams for competitions like the World Cup! England is the largest of the four countries, and for convenience it is divided roughly into three zones. The zone nearest France is called the South of England, the middle zone is called the Midlands and the one nearest to Scotland is known as the North. You find most of the population settled in the south, but most of the industrial cities in the Midlands and the North of England. Although, nationwide, these cities are not as large as those in China, they have world-famous football teams and some of them even have two! It is a pity that the industrial cities built in the nineteenth century do not attract visitors. For historical architecture you have to go to older but smaller towns built by the Romans. There you will find out more about British history and culture. The greatest historical treasure of all is London with its museums, art collections, theatres, parks and buildings. It is the centre of national

人教版高中英语必修五知识点详解 Units 1-2 1. doubt doubt是高考中的高频考查词汇。doubt可作动词和名词，是新课标重点词汇。其命题角度为：①作动词时， 若为肯定句，后跟宾语从句,通常用if/whether引导，若为否定句，则通常用that引导。 ②doubt作名词时，通常用于There is no doubt that ...(毫无疑问）结构。2010年高考对doubt的考查还将集中 在其后跟从句时连接词的选择上，也有可能将doubt与其他动词或名词放在一起进行词义辨析。 2. expose expose是新课标要求掌握的单词，应重点掌握它的义项及常见用法，特别是be exposed to 句式，其中to为介词，后跟名词、代词和动名词；同时注意exposed to作后置定语和用于句首作状语的用法。另外，being exposed to结构用动名词形式作主语也是重点和难点，极易考查。 预测2010年命题方向为exposed to 作状语和定语的用法。 3. absorb absorb是新课标重点单词，重点掌握其“吸收（液体，热）；吸收，理解（知识）”的词义及其be absorbed in(全神贯注于……)的用法，易考点为该短语位于句首作状语和作后置定语两点，考生应能掌握be absorbed by(为某事物所吸引)；还应联系be engaged in, be devoted to, be involved in和be lost in等常见重点近义短语。 4. apart from apart from是常见介词短语，意为“除……之外”，考生应熟练掌握近义的词和短语：except, besides, in addition (to), other than, except for, except that, except when等。预测2010年高考会在单项填空题中直接考查或者会出现 在阅读理解题中。 5. available available是新课标重点单词，在近几年高考和各地的模拟考试中出现的频率极高，主要考点为：①词义(可得到的，可用的)。命题形式常为形容词词义辨析，如区分accessible, acceptable, sensible, favourite, average, convenient 等。②用法。be available to意为“可利用的”，be available for意为“使……可以享受某物;使……买得起某物”, 要了解二者的区别。 预测2010年高考命题会以考查词义或者形容词短语作后置定语为命题方向。 6. consist of consist of是近几年高考高频考查短语。①理解其词义“组成，构成”。②考查与其他近义词组的用法异同点。 如be made up of, be composed of, constitute, be formed of 等。考生要特别注意consist of要用主动形式表达， 不用系表结构。预测这一考点将成为2010年高考考查的重点，特别是用consisting of 作后置定语。 7. break down 由break构成的动词短语是历年高考命题的重点。考生必须明确break down的几个常见义项，根据不同的语 境加以判断。break down，break up, break off, break away, break in等，都要求考生熟知它们的常见义项，因为 命题时可能会对该短语直接考查，也可在短文中考查对其意义的理解。 8. only+状语（状语从句）位于句首构成部分倒装 这是考生必须熟练掌握的句式之一，以往的高考题中已多次考查到。倒装句式有多种情况，该句式为日常交 际中较常见的一种。特别提示：only只有强调状语或者状语从句才构成部分倒装，强调主语或宾语不用倒装。 预测该句式是2010年高考命题考查的重点。 重要词汇拓展 Unit 1 Great scientists 1. ____ n. 特征；特性 2. _____ vt.&vi. 结束；推断出→______ n. 结论 3. _____ vt. 打败；战胜；使受挫 4. ______ vt. 参加；出席；照顾；护理→_____ n. 参加；出席；侍从；看护 5. _____ vt. 暴露；揭露；使曝光→_____ n. 暴露；揭穿；揭发 6. _____ vt.& n. 治愈；痊愈→______adj.可治愈的 ______ vt.& n. 控制；支配 8. _____ vt. 吸收；吸引；使专心→______adj. 被吸收的；全神贯注的 9. _____ adj. 严重的；严厉的；剧烈的 characteristic 2. conclude；conclusion 3. defeat 4. attend；attendance 5. expose；exposure 6. cure；curable 7. control 8. absorb；absorbed 9. severe 10. _____ vt. 宣布；通告→______n. 宣布；宣告；通知 11. ______ vt. 命令；指示；教导→_____ adj.有教育意义的；有指导意义的→_____n.指导；指示；指令→_____ n. 教师；讲师；指导员 12. _____ vt.&vi. 捐献；贡献；捐助→______n.贡献；奉献 13. _____ adj. 有创造力的；创造性的；独创的→______n.创造；创作 14. _____ adj. 热情的；热心的→______ n. 热心；热情

新人教版高中英语课文译文 必修五 第一单元伟大的科学家 Reading 约翰.斯诺击败“霍乱王” 约翰.斯诺是伦敦一位著名的医生—他的确医术精湛，因而成为照料维多利亚女皇的私人医生。但当他一想到要帮助那些得了霍乱的普通百姓时，他就感到很振奋。霍乱在当时是最致命的疾病，人们既不知道它的病源，也不了解它的治疗方法。每次暴发霍乱时，就有大批惊恐的老百姓病死。约翰.斯诺想面对这个挑战，解决这个问题。他知道，在找到病源之前，霍乱疫情是无法控制的。 斯诺对霍乱致人死地的两种推测都很感兴趣。一种看法是霍乱病毒在空气中腐殖着，像一股危险的气流到处漂浮，直到找到病毒的受害者为止。第二种看法是在吃饭的时候人们把这种病毒引入体内的。病从胃里发作而迅速殃及全身，患者就会很快地死去。 斯诺推测第二种说法是正确的，但是他需要证据。因此，在1854年伦敦再次暴发霍乱的时候，约翰.斯诺着手准备对此调研。当霍乱在贫民区迅速蔓延的时候，约翰.斯诺就开始收集资料。他发现特别在两条街道上霍乱流行的很严重，在10天之内就死去了500多人。他决心要查明其原因。 首先，他在一张地图上标明了所有死者住过的地方。这提供了一条说明霍乱起因的很有价值的线索。许多死者是住在宽街的水泵附近（特别是这条街上16、37、38、40号）。他发现有些住宅（如宽街上20号和21号以及剑桥上的8号和9号）却无人死亡。他以前没预料到这种情况，所以他决定深入调查。他发现，这些人都在剑桥街7号的酒馆里打工，而酒馆为他们免费提供啤酒喝，因此他们没有喝从宽街水泵抽上来的水。看来水是罪魁祸首。 接下来，约翰.斯诺调查了这两条街的水源情况。他发现，水是从河里来的，而河水被伦敦排出的脏水污染了。他马上叫宽街上惊慌失措的老百姓拆掉水泵上的把手。这样，水泵就用不成了。不久，疫情就开始得到了缓解。他证明了，霍乱是由病菌而不是由气团传播的。 在伦敦的另一个地区，他从两个与宽街暴发的霍乱有关联的死亡病例中发
