人教版新课标高中英语选修7课文原文 Unit 1 Living well-Reading MARTY’S STORY Hi, my name is Marry Fielding and I guess you could say that I am "one in a million". In other words, there are not many people like me. You see, I have a muscle disease which makes me very weak, so I can't run or climb stairs as quickly as other people. In addition, sometimes I am very clumsy and drop things or bump into furniture. Unfortunately, the doctors don't know how to make me better, but I am very outgoing and have learned to adapt to my disability. My motto is: live One day at a time. Until I was ten years old I was the same as everyone else. I used to climb trees, swim and play football. In fact, I used to dream about playing professional football and possibly representing my country in the World Cup. Then I started to get weaker and weaker, until I could only enjoy football from a bench at the stadium. In the end I went into hospital for medical tests. I stayed there for nearly three months. I think I had at least a billion tests, including one in which they cut out a piece of muscle from my leg and looked at it under a microscope. Even after all that, no one could give my disease a name and it is difficult to know what the future holds. One problem is that I don't look any different from other people. So sometimes some children in my primary school would laugh, when I got out of breath after running a short way or had to stop and rest halfway up the stairs. Sometimes, too, I was too weak to go to school so my education suffered. Every time I returned after an absence, I felt stupid because I was behind the others. My life is a lot easier at high school because my fellow students have accepted me. The few who cannot see the real person inside my body do not make me annoyed, and I just ignore them. All in all I have a good life. I am happy to have found many things I can do, like writing and computer programming. My ambition is to work for a firm that develops computer software when I grow up. Last year invented a computer football game and a big company has decided to buy it from me. I have a very busy life with no time to sit around feeling sorry for myself. As well as going to the movies and football matches with my friends, I spend a lot of time with my pets. I have two rabbits, a parrot, a tank full of fish and a tortoise. To look after my pets properly takes a lot of time but I find it worthwhile. I also have to do a lot of work, especially if I have been away for a while. In many ways my disability has helped me grow stronger psychologically and become more independent. I have to work hard to live a normal life but it has been worth it. If I had a chance to say one thing to healthy children, it would be this: having a disability does not mean your life is not satisfying. So don't feel sorry for the disabled or make fun of them, and don't ignore them either. Just accept them for who they are, and give them encouragement to live as

高中化学学习材料 《有机化学基础》知识点整理 一、重要的物理性质 1. 有机物的溶解性 (1) 难溶于水：各类烃、卤代烃、硝基化合物、酯、绝大多数高聚物、高级的醇、醛、羧酸等。 (2) 易溶于水：低级[n(C)≤4]醇、(醚)、醛、(酮)、羧酸及盐、氨基酸及盐、单糖、二糖。(都能与水形成氢键)。 (3) 具有特殊溶解性的： ①乙醇是一种很好的溶剂，既能溶解许多无机物，又能溶解许多有机物，所以常用乙醇来溶解植物色素或其中 的药用成分，也常用乙醇作为反应的溶剂，使参加反应的有机物和无机物均能溶解，增大接触面积，提高反应速率。例如，在油脂的皂化反应中，加入乙醇既能溶解NaOH，又能溶解油脂，让它们在均相（同一溶剂的溶液）中充分接触，加快反应速率，提高反应限度。 ②苯酚：室温下，在水中的溶解度是9.3g（属可溶），易溶于乙醇等有机溶剂，当温度高于65℃时，能与水混溶， 冷却后分层，上层为苯酚的水溶液，下层为水的苯酚溶液，振荡后形成乳浊液。苯酚易溶于碱溶液和纯碱溶液，这是因为生成了易溶性的钠盐。 ③乙酸乙酯在饱和碳酸钠溶液中更加难溶，同时饱和碳酸钠溶液还能通过反应吸收挥发出的乙酸，溶解吸收挥发 出的乙醇，便于闻到乙酸乙酯的香味。 ④有的淀粉、蛋白质可溶于水形成胶体。蛋白质在浓轻金属盐（包括铵盐）溶液中溶解度减小，会析出（即盐析， 皂化反应中也有此操作）。但在稀轻金属盐（包括铵盐）溶液中，蛋白质的溶解度反而增大。 ⑤线型和部分支链型高聚物可溶于某些有机溶剂，而体型则难溶于有机溶剂。 ⑥氢氧化铜悬浊液可溶于多羟基化合物的溶液中，如甘油、葡萄糖溶液等，形成绛蓝色溶液。 2. 有机物的密度 (1) 小于水的密度，且与水（溶液）分层的有：各类烃、一氯代烃、酯（包括油脂） (2) 大于水的密度，且与水（溶液）分层的有：多氯代烃、溴代烃（溴苯等）、碘代烃、硝基苯 3. 有机物的状态[常温常压（1个大气压、20℃左右）] (1) 气态： ①烃类：一般N(C)≤4的各类烃注意：新戊烷[C(CH3)4]亦为气态 ②衍生物类： 一氯甲烷（CH3Cl，沸点为-24.2℃）氟里昂（CCl2F2，沸点为-29.8℃） 氯乙烯（CH2=CHCl，沸点为-13.9℃）甲醛（HCHO，沸点为-21℃） 氯乙烷（CH3CH2Cl，沸点为12.3℃）一溴甲烷（CH3Br，沸点为3.6℃） 四氟乙烯（CF2=CF2，沸点为-76.3℃）甲醚（CH3OCH3，沸点为-23℃） 甲乙醚（CH3OC2H5，沸点为10.8℃）环氧乙烷（，沸点为13.5℃） (2) 液态：一般N(C)在5～16的烃及绝大多数低级衍生物。如，

高中化学选修五第一章知识点（附练习）一、有机化合物和无机化合物的区别 性质和反应有机物无机物溶解性多数不溶于水，个别特殊除外（如乙醇、 乙酸） 部分溶于水而不溶于有机溶剂 耐热性多数不耐热，熔点低，一般在400℃以 下 多数耐热，难熔化，熔点一般较高可燃性多数可燃烧，个别除外（如CCl4）多数不可燃烧 电离性多数是非电解质，个别除外（如有机酸）多数是电解质（如酸、碱、盐、活泼金 属氧化物、水） 化学反应一般比较复杂，多副反应，反应速率较 慢一般比较简单，副反应少，反应速率较 快 二、有机化合物的分类 有机化合物按照组成元素可分为烃和烃的衍生物。 有机化合物从结构上有两种分类方法：按碳的骨架分类和按官能团分类。 1、按碳的骨架分类 链状化合物：如CH3CH2CH2CH3 有机化合物脂环化合物：如 环状化合物 芳香化合物：如 2、按官能团分类 官能团的概念：决定化合物特殊性质的原子或原子团。 官能团和根、基的区别：基是有机物中去掉某些原子或原子团后剩下的原子或原子团，呈电中性，不稳定且不能独立存在，显然官能团属于基的一种；根是电解质电离后的原子或原子团，带电荷，稳定可独立存在于溶液或熔化状态。基和根可相互转化，如-OH和OH-。 具体分类情况见表. 脂肪烃
注意：羟基与苯环上的碳原子相连的化合物为酚，羟基与非苯环上的碳原子相连的化合物为醇！ 练习： 1、迄今为止，以下各族元素中生成化合物的种类最多的是（ C ） A.II A 族 B.III A 族 C.IV A 族 D.V A 族 2、下面的原子或原子团不属于官能团的是（A ） A.Cl - B.-COOH C.-OH D.-CO- 3、下列物质中属于酚类的是（ D ） A.CH 3CH 2CH 2OH B.CH 3CH(OH)CH 3 C. D.
马蒂的故事 你好。我叫马蒂．菲尔丁。我想你可能会说我是“百万人中才有一个”的那种人。换句话说，世界上像我这样的人并不多见。你瞧，我的肌肉有毛病，使我的身体非常虚弱，所以我不能像别人那样快跑或快步爬楼梯。再说，有时候我还会笨手笨脚、不小心摔掉东西，或磕碰到家具上。不幸的是，大夫们不知道如何治好我的病，但是我很开朗乐观，学会了适应身体的残疾。我的座右铭是：活一天算一天。 十岁以前，我跟其他人是一样的。我常常爬树、游泳、踢足球。说实在的，我过去常常梦想我会成为职业球员，代表我们的国家参加世界杯足球赛。后来，我的身体开始变得越来越虚弱，以至于只能坐在体育场的长凳上欣赏足球了。最后我到医院去做了检查，几乎住了三个月的医院。我想我至少做过十亿次检查了，包括有一次检查，他们从我的腿部切下一小块儿肌肉，放在显微镜下观察。即使做过了所有这些检查，也没有人能够确诊这个病。因此，很难知道将来会是个什么样子。 问题是我看上去跟平常人一样。因此，当我跑了很短的一段路之后，我就会喘不过气来，或者爬楼梯才爬到一半就得停下来休息。因此，上小学时有的孩子见了我这种情况就会笑话我。有时候我的身体太虚弱，上不了学，因此落了许多功课。每次缺课之后，我就觉得自己很笨，因为我比别人落后了。 我在中学时期的生活(比在小学时)要轻松多了，因为我的同学开始接受了我的状况。还有些同学看不到我的内心世界，但是我并不生气，只是不去理会他们罢了。总而言之，我生活得挺好。我很高兴我能做许多事情，比如写作和电脑编程。我有雄心壮志，长大后我要在开发电脑软件的公司里工作。去年我发明了一个电脑足球游戏，有一家大公司已经决定从我这儿买走。我的生活很充实，没有时间闲坐着顾影自怜。除了同我的朋友一起去看电影和足球比赛，我还花很多时间和我的宠物在一起。我有两只兔子、一只鹦鹉、一缸金鱼和一只乌龟。我得花大量时间来照顾这些宠物，但我觉得很值。此外，我还有好多功课，特别是在病了一段时间之后。 在许多方面，我身体的残疾倒使我心理上变得更加坚强、更加独立。我必须努力工作才能过上正常的生活，但这是值得的。假如我有机会跟健康孩子讲一句话，那么，这句话就是：身体残疾并不意味着生活不美满。因此，不要感到残疾人可怜，或者取笑他们，也别不理睬他们。要接受他们，给他们以鼓励，让他们能像你一样过得丰富多彩、充实美满。 谢谢你们读我的故事。．马蒂 致建筑师的一封信桑达斯女士 爱丽斯。梅杰 总建筑师剑桥街64号 影院设计公司班克斯敦 希尔街44号 班克斯敦 20(0年9月2,4日 亲爱的桑达斯女士： 今天我从报上了解到，您将成为班克斯敦新影院的建筑设计师。我希望您不介意我写信询问您是否已考虑到残疾顾客的需要。尤其是以下几点不知您是否考虑到了： 1．为乘坐轮椅的人进入电影院提供充分的便利。影院内的各个部分都安装电梯就会很方便。电梯的按钮应当让乘坐轮椅的人容易够到，电梯门应足够宽。在有些电影院里，(残疾人专用)电梯设在影院背后阴冷而不显眼的地方。由于残疾人必须要使用这些电梯，这就使残疾人感到比别的观众低一等。 2．给听力有障碍的人提供耳机。所有座位的旁边都装有耳机，而不是少数几个座位，那会有帮助。这样可以使那些听力有缺陷的观众和那些听力正常的朋友坐在一起欣赏，而不是让前者坐在一个特定的区域。

She is a lovely girl. But at the age of ten，she became disabled in a big fire，which made her left eye blind and right arm lost. She didn't give up anything in spite of her disability. Not only has she learned to take care of herself，but also she encourages other disabled people to face life bravely and lead an active life. Wang Hong learns hard and takes the head in our class. And we are all inspired by her. We hope other people don't look down upon the disabled. What healthy people should do is do what we can to help them，such as making public equipment more convenient for them to use. 高频单词 1．disability (n.) 伤残；无力；无能→disabled (adj.) 伤残的 2．adapt (vt.) 使适应；改编→adaptation (n.) 适应；改编；改写本

备战高中：梳理选修五知识点 结构相似，在分子组成上相差一个或若干个CH2原子团的物质物质。 同系物的判断要点： 1、通式相同，但通式相同不一定是同系物。 2、组成元素种类必须相同 3、结构相似指具有相似的原子连接方式，相同的官能团类别和数目。结构相似不一定完全相同，如CH3CH2CH3和(CH3)4C，前者无支链，后者有支链仍为同系物。 4、在分子组成上必须相差一个或几个CH2原子团，但通式相同组成上相差一个或几个CH2原子团不一定是同系物，如CH3CH2Br和 CH3CH2CH2Cl都是卤代烃，且组成相差一个CH2原子团，但不是同系物。（马上点标题下蓝字"高中化学"关注可获取更多学习方法、干货！） 5、同分异构体之间不是同系物。 二、同分异构体 化合物具有相同的分子式，但具有不同结构的现象叫做同分异构现象。具有同分异构现象的化合物互称同分异构体。 1、同分异构体的种类：
⑴碳链异构：指碳原子之间连接成不同的链状或环状结构而造成的异构。如C5H12有三种同分异构体，即正戊烷、异戊烷和新戊烷。 ⑵位置异构：指官能团或取代基在在碳链上的位置不同而造成的异构。如1—丁烯与2—丁烯、1—丙醇与2—丙醇、邻二甲苯与间二甲苯及对二甲苯。 ⑶异类异构：指官能团不同而造成的异构，也叫官能团异构。如1—丁炔与1，3—丁二烯、丙烯与环丙烷、乙醇与甲醚、丙醛与丙酮、乙酸与甲酸甲酯、葡萄糖与果糖、蔗糖与麦芽糖等。 ⑷其他异构方式：如顺反异构、对映异构（也叫做镜像异构或手性异构）等，在中学阶段的信息题中屡有涉及。 各类有机物异构体情况：
