A. give B. have f C. learn D. makeIII. 阅读理解A) I have never taken cooking classes. I learned cooking from my mother because she was really interested in teaching me how to cook. The main reason for this was because when my mother got married, she didn’t know how to cook anything, not even an egg. My grandmother never allowed her to stay in the kitchen when she was cooking.My mother did not start to cook until she was 25 years old. In the beginning, it was very hard for her. Therefore, she had to take cooking classes to prepare our meals. After having that experience, she decided to teach me how to cook because she didn’t want me to have the same experience.I remember when I was seven years old, and my other was cooking, I was with her in the kitchen enjoying cooking.I always helped her. Sometimes we prepared meals that my mother already knew how to make, and sometimes we prepared them from recipes. Nowadays, I am really thankful for that experience because I don’t need help to cook a meal.I can cook for me alone or for a group of people; it doesn’t matter.I will do the same with my children because I don’t want them to have the same experience as my mother. If one day I am not with them, I want to be sure that they can carry on their lives without me.41.

The four texts above are most probably ______.A. lettersB. noticesC. invitationsD. advertisementsC) Many years ago when people had no thermometers(温度计), they usually touched a thing to see how hot or cold it was. The following experiment shows easy it was to make a mistake.Take three glasses: the first one with very hot water, the second one with very cold water, and the third one with water at room temperature. Then you put a finger of one hand in the hot water, and a finger of the other hand in the cold water. You hold your fingers in the two glasses for a That is minute. Then you use each finger, one after another, one after another, to see how hot or cold the water in the third glass is. You will find that the water is warm to the finger that was in the cold water before, but the finger which was in the hot water will feel cold in the same glass of water.That is why you must always find the temperature in a scientific way. You must not try to tell the temperature as it seems to you.You will often make a mistake if you take something that seems to you for a real fact. For example, when you are going to an Amusement park by bus and you want to get there very quickly, it seems to you that your bus is going very slowly, slower than the other buses. But if it is Sunday and you have much free time, it seems to you all the buses and cars are going very fast.51. The experiment tells us that sometimes it is ______ to make a mistake.A. interestingB. difficultC. easyD. helpful52. The water in the third glass is ______.A. colder than the water in the first glassB. hotter than the water in the first glassC. colder than the water in the second glassD. as cold as the water in the second glass53. What will you find if you put the finger which was in the first glass into the second glass according to theexperiment?A. The water is hotter than it is in the first glass.B. The water is as hot as it is in the first glass.C. The water is at room temperature.D. The water is colder than it is in the first glass.54. How should we find the temperature according to the passage?A. Try to tell as it seems to us.B. Try to use our fingers.C. Try to tell in a scientific way.D. Try to touch something to see how hot it is.55. We can learn something about ______ from the passage.A. physicsB. chemistryC. psychology(心理学)D. biology(生物学)IV56a meal. Today, fast food is 57 cheap, which makes it even more attractive. And it is everywhere—not only in the United States 58 around the world. Now, 59 , there is a group of people who would like to see us stop 60 so much fast food. These people belong to the Slow Food Movement.The Slow Food Movement started in Italy in 1986. It was 61 by Carlo Petrini, a food critic who 62 owned a restaurant. He and his friends wanted to encourage more people to slow 63 and learn to prepare and enjoy good food again. 64 began by meeting in small 65 to organize dinners and wine tastings. They also began to encourage 66 local farmers to go back to the old ways of growing food and caring for farm animals. They felt that food that was raised carefully tasted 67 .This small Italian group grew, 68 in 1989 the International Slow Food Movement was born in Paris. Today there 69 78,000 members in 100 countries. There is also a 70 magazine, printed in six languages, including Japanese.V. 短文改错Cell phones can be see almost everywhere in 71. ________school now.

说明：多项式乘法的结果一般是按某个字母的降幂或升幂排列．
【公式 2】 (a + b)(a 2 − ab + b2 ) = a3 + b3 (立方和公式)
证明: (a + b)(a 2 − ab + b2 ) = a3 − a 2b + ab2 + a 2b − ab2 + b3 = a3 + b3
2(x + 3)(x − 3)
2(x + 3)(x − 3) 2(x + 3)
说明：(1) 分式的乘除运算一般化为乘法进行，当分子、分母为多项式时，应先因式分解再进行约分化简；(2) 分式的计算结果应是最简分式或整式．
4、…、10 的立方数，是非常有好处的．
【例 4】已知 x 2 − 3x = 1 = 0 ，求 x3 + 1 的值． x3
解： x2 − 3x = 1 = 0 ∴ x ≠ 0 ∴ x + 1 = 3
x
原式= (x + 1 )(x2 −1 + 1 ) = (x + 1 )[(x + 1 )2 − 3] = 3(32 − 3) = 18
a3 + b3 = (a + b)[(a + b)2 − 3ab] = −c(c2 − 3ab) = −c3 + 3abc ∴ a3 + b3 + c3 = 3abc ②，把②代入①得原式= − 3abc = −3
abc
说明：注意字母的整体代换技巧的应用．引申：同学可以探求并证明：
a3 + b3 + c3 − 3abc = (a + b + c)(a 2 + b2 + c 2 − ab − bc − ca)

3．在下列化合物中，只有在溶液中才能导电的电解质是()A．NaCl B．酒精C．NH4HCO3D．CH3COONa【答案】C【解析】A项和D项，NaCl、CH3COONa在水溶液或熔融状态下都能导电；B项酒精为非电解质，不能导电；C项NH4HCO3虽然是强电解质，但熔化前已分解。

4．下列关于电解质电离的叙述中正确的是()A．CaCO3在水中溶解度很小，其导电能力很弱，所以CaCO3是弱电解质B．CaCO3在水中溶解度很小，但溶解的CaCO3全部电离，所以CaCO3是强电解质C．氯气和氨气的水溶液导电性都很好，所以它们是强电解质D．水难电离，纯水几乎不导电，水是非电解质【答案】B【解析】CaCO3不是弱电解质，因为溶解的部分全部电离，氯气和氨气在水中均不能电离出离子，它们不是电解质，之所以能够导电是因为生成了电解质HCl、HClO和NH3·H2O。

水是极弱的电解质。

初高中化学衔接知识点+配套练习

高一化学初高中知识衔接解析与练习主要内容主要通过对物质的组成、分类以及物质之间的关系的总结,对初中所学内容进行整合,又为高中化学的学习打下基础;使同学们能在直观的层面上较明显的认识物质分类及同类物质间的相似性及其应用;认识分类这种科学方法对化学研究的作用;了解物质的组成、结构和性质的关系;起到初中化学和高中化学衔接的作用;知识点精析化学是研究物质的组成、结构、性质及变化规律的一门自然科学;在初中我们已经了解了一些物质组成和结构的知识,对元素、分子、原子——等基本概念有了一定的认识;进入高中的学习我们不仅要能从以前学过的微观、宏观来认识物质,更应该从物质的结构入手以体会结构决定性质;当然除了了解物质的组成我们还会在今后进一步去学习那些肉眼看不到的微粒是靠什么作用结合在一起的,这些作用会导致物质的性质有什么不同,从而理解物质结构决定性质的道理;随着人类社会的进步,科学知识的丰富,原来那些只靠经验得到的化学成果已经无法满足人类的需求;一系列新的问题摆在化学家的面前要求得到圆满的回答;为什么煤能燃烧而其他的岩石却不能金属为什么会生锈为什么柔软的高岭土经过高温的焙烧就变成了晶莹坚固的花瓶要得到这些问题的谜底,人类就必须对世界上的一切物质进行研究;可是我们所研究的对象是一个非常庞大的集体,所以为了更好地认识物质,人们常根据物质的组成、状态、性能等对物质进行分类;“分类”是学习化学非常重要的一个学习方法;例如：根据组成对物质的分类：混合物、纯净物；单质、化合物；金属、非金属；氧化物、酸、碱、盐,我们可将它们以图表的形式展现出来;例如：各类物质的概念及代表物在这里要说明的是同一类物质在性质上相似,例如酸性氧化物,它还有一个俗名叫酸酐;我们中学所学的酸酐中大多数都能溶于水,不溶于水的很少像SiO2;于是同学们在学习的时候就应该记少的那半儿;而碱性氧化物中能溶于水的比较少见的有K、Na、Ba、Ca的氧化物;如何判断酸性氧化物和它对应的酸呢我们从已学过的知识入手,例如：C的氧化物我们学过两种即CO、CO2,那么谁是H2CO3的酸酐呢我们的回答应该是CO2,它们之间的关系呢进一步观察我们会发现CO2、H2CO3中的C元素都是+4价,因此今后我们可以用这种方法去判断酸性氧化物和它对应的酸;我们知道化学的研究对象是物质,随着学习的不断深入,你还要用发展的眼光不断地总结积累,你会发现碱性氧化物都是金属氧化物而酸性氧化物不都是非金属氧化物;当然物质分类的方式不仅一种,根据我们研究的对象及内容的不同,可把我们研究的物质按不同的方式分类;例如：酸我们可以按元数分电离H原子的个数；从是否含氧含氧酸、无氧酸；从电离的程度强酸和弱酸；做氧化剂的元素的不同氧化性酸和非氧化性酸等;同理,像碱、盐等其它物质也可以多种分类;通过把不同的物质进行分类,我们会发现同一类别的物质在性质上有相似的地方即我们通常说的通性,然后在今后的学习中我们再通过物质结构等知识的学习,进一步去研究物质间的规律,就会逐步掌握元素化合物学习的规律和方法,变被动学习为主动学习;物质分类的作用除了便于了解掌握同类物质的性质还在于引导我们去发现物质之间的转化关系,下面我们就对单质、氧化物、酸、碱和盐之间的相互关系进行以下讨论：O2H2O （）C——（）——（）——CaCO3（）（）HClBa——（）——Ba(OH)2——（）相信同学们利用初中所学知识不难完成上述转化关系,接下来同学们可以以单质、氧化物、酸、碱和盐分别为出发点去寻找它们之间的反应关系并将它们之间的关系绘制成一个表格,在这里给同学们举一个例子：从这两条系列、八个点,我们不难看出这些物质在纵向上的衍生关系以及横向及交叉的相互关系,八点图间蕴藏了多少化学反应,下面我们就重点解读一下“八点图”中的反应;1. 金属单质＋非金属单质→无氧酸盐2. 碱性氧化物＋酸性氧化物→含氧酸盐3. 碱＋酸→盐＋水4. 酸性氧化物＋碱→盐＋水5. 碱性氧化物＋酸→盐＋水6. 酸＋盐→新酸＋新盐7. 碱＋盐→新碱＋新盐8. 盐＋盐→新盐＋新盐9. 金属单质＋盐→金属单质＋盐10. 金属单质＋酸→盐＋H2我们应该怎样运用这些关系,在用的过程中要注意些什么呢一. 找规律：我们都很熟悉碱＋酸→盐＋水,通过对3、4、5的观察你会发现酸性氧化物广义上来讲就是酸,碱性氧化物在广义上就是碱,这样在今后的学习中我们就可以用这个规律去书写化学方程式;例如：CO2+CaOH2＝CaCO3↓+H2O SO2+CaOH2＝CaSO3↓+H2O二. 反应条件限制：1. 酸＋金属→盐＋H2金属为活泼金属；酸一般用稀硫酸、稀盐酸；不用两者,稀HNO3制备氢气时,不用K、Ca、Na特别活泼的金属；2. 碱＋盐碱+盐反应时要求两者都必须可溶,生成物之一为不溶即可；3. 碱＋指示剂碱必须可溶;三. 酸和盐反应的规律：1. 强酸制备弱酸 2HCl+CaCO3＝CaCl2+CO2↑+H2O2HCl+Na2SO3＝2NaCl+SO2↑+H2O2. 高沸点、难挥发性酸制备低沸点、易挥发性酸2NaCl+H2SO4浓＝Na2SO4＋2HCl↑ NaNO3+H2SO4浓＝NaHSO4＋HNO3↑当然我们不是想把所有的知识局限在“八点图”上,而是以它为例说明如何寻找各类物质之间的关系,同学们也可以从不同的角度进行总结归纳;解题方法指导例1. 下列说法正确的是：A非金属氧化物都是酸性氧化物B凡是酸性氧化物都可以直接与水反应生成相对应的酸C与水反应生成酸的氧化物,不一定是该酸的酸酐D金属氧化物都是碱性氧化物本题考察同学对氧化物的分类,酸酐及酸的认识,由于像CO、NO这些不成盐氧化物所以A不对;SiO2难溶于水,Al2O3为两性氧化物故C正确;2. 下列关于氧化物的叙述正确的是：A酸性氧化物均可与碱反应B酸性氧化物在常温常压下均为气态C金属氧化物都是碱性氧化物 D不能跟酸反应的氧化物一定能跟碱反应本题要求利用初中对酸性氧化物性质的知识的积累,不难得出酸性氧化物在广义上可认为就是酸,不难得出A正确;3. 下列物质中：①Cl2O7,HClO ②SO2,H2SO4③NO2,HNO3④SiO2,H2SiO3⑤Mn2O7,HMnO4酸与酸酐相对应的是A②③ B③④ C④⑤ D①③④抓住酸酐与其对应的酸中该元素的化合价一致这一特点即可选出C正确;典型例题分析1. 只含有一种元素的是A. 可能是纯净物也可能是混合物B. 可能是单质也可能是化合物C. 一定是纯净物D. 一定是一种单质解析：在今后的学习中我们还要学习同素异形体的概念,即同种元素组成的不同的单质叫做同素异形体,那么像P元素可以形成白磷或红磷等单质,而白磷或红磷是两种不同的物质;所以A选项正确;2. 下列有关氧化物的叙述正确的是A. 酸性氧化物均可跟碱起反应B. 金属氧化物都是碱性氧化物C. 非金属氧化物都是酸性氧化物D. 不能跟酸反应的氧化物一定能跟碱反应解析：在高中的学习中要不断地总结和积累,逐渐加深对概念的理解;例如：Al2O3是两性氧化物,NO、CO是不成盐氧化物既不与酸也不与碱反应成盐;因此,只有A正确;3. 00年全国下列广告用语在科学性上没有错误的是A. 这种饮料中不含有任何化学物质B. 这种蒸馏水绝对纯净,其中不含有任何离子C. 这种口服液含丰富的氮、磷、锌微量元素D. 没有水就没有生命解析：这是生活中经常遇到的话,考察同学们对基本概念的综合应用能力;答案为D强化练习一、标出下列指定元素的化合价N．2、N．H3、N．H4Cl、N．O、N．O2、N．2O4、HN．O3；H2S．、S．O2、S．O3、H2S．O4、BaS．O4；C．l2、NaC．l、HC．l、HC．lO、HC．lO4、HC．lO3、KC．lO3；C．H4、C．O、C．O2、H2C．O3、NaHC．O3、CaC．O3；在下列化合物中根原子团下方划一短线,并标出根的化合价①
