高考化学复习指导四招定高分
高三化学复习是一项系统的学习工程，要提高复习效率，就需要注重学习方法的探索，不仅要想方设法跟上老师的复习思路，还要根据自己的实际情况进行调整。如何来搞好这一年的化学复习呢？结合教学实际，我认为，必须注意以下四个招数：
招数一：善待课本，巩固双基，挖掘隐形关系
课本和教材是专家、学者们创造性的研究成果，经过长期、反复的实践和修订，现已相当成熟，书本里蕴含着众多科学思想的精华。
据初步统计，中学化学所涉及的概念及理论大大小小共有220多个，它们构建了中学化学的基础，也就是说，基本概念及基本理论的复习在整个化学复习中起着奠基、支撑的重要作用，基本概念及基本理论不过关，后面的复习就会感到障碍重重。因此，必须切实注意这一环节的复习，讲究方法，注重实效，努力把每一个概念及理论真正弄清楚。
例如对催化剂的认识，教材这样定义：“能改变其他物质的化学反应速率，而本身的质量和化学性质都不改变的物质”。几乎所有学生都能背诵，粗看往往不能理解其深层含义；假如我们对其细细品味一番，枯燥的概念就会变得生动有趣――我们可以思索一下“催化剂是否参与了化学反应？“对化学反应速率而言，‘改变’一词指加快或是减慢？”“‘化学性质都不改变’，那物理性质会变吗”等问题。经过一番折腾，对催化剂的认识就会达到相当高的层次。
再者，课本中的众多知识点，需要仔细比较、认真琢磨的非常多。例如原子质量、同位素相对原子质量、同位素质量数、元素相对原子质量、元素近似相对原子质量；同位素与同分异构体、同系物、同素异形体、同一物质等等。对课本中许多相似、相关、相对、相依的概念、性质、实验等内容，应采用比较复习的方法。通过多角度、多层次的比较，明确其共性，认清其差异，达到真正掌握实质之目的。
透析近几年的高考化学实验题，可以发现几乎所有试题均来自课本上的学生演示实验及课后学生实验。因此，在老师指导下，将十几个典型实验弄清原理，反复拆开重组，相信你定会大有所获。
招数二：经常联想，善于总结，把握知识网络
经过，高一高二阶段化学的学习，有些同学觉得个别知识点已学会。其实，高考考场得分，学会仅是一方面，还应总结归纳、经常联想，找出同类题解法的规律，才能更有把握不失分。也就是说，化学学习，重在掌握规律。有人说，化学难学，要记的东西太多了，这话不全对。实际上，关键在于怎样记。例如对无机化学来说，我们学习元素及其化合物这部分内容时，可以以“元素→单质→氧化物(氢化物)→存在”为线索；学习具体的单质、化合物时既可以“结构→性质→用途→制法”为思路，又可从该单质到各类化合物之间的横向联系进行复习，同时结合元素周期律，将元素化合物知识形成一个完整的知识网络。
有机化学的规律性更强，“乙烯辐射一大片，醇醛酸酯一条线”，熟悉了官能团的性质就把握了各类有机物间的衍变关系及相互转化；理解了同分异构体，就会感觉到有机物的种类繁多实在是微不足道……这样，通过多种途径、循环往复的联想，不仅可以加深对所学知识的记忆，而且有助于思维发散能力的培养。实践证明，光有许多零碎的知识而没有形成整体的知识结构，就犹如没有组装成整机的一堆零部件而难以发挥其各自功能。所以在高三复习阶段的重要任务就是要在老师的指导下，把各部分相应的知识按其内在的联系进行归纳整理，将散、乱的知识串成线，结成网，纳入自己的知识结构之中，从而形成一个系统完整的知识体系。
招数三：讲究方法，归纳技巧，勇于号脉高考
纵观近几年化学高考试题，一个明显的特征是考题不偏、不怪、不超纲，命题风格基本保持稳定，没有出现大起大落的变化。很明显，命题者在向我们传输一个信号：要重视研究历年高考题！高考试题有关基本概念的考查内容大致分为八个方面：物质的组成和变化；相对原子质量和相对分子质量；离子共存问题；氧化还原反应；离子方程式；物质的量；阿佛加德罗常数；化学反应中的能量变化等等。
基本技能的考查为元素化合物知识的的横向联系及与生产、生活实际相结合。因此，对高考试题“陈”题新做，将做过的试题进行创造性的重组，推陈出新，不失是一个好办法。高考命题与新课程改革是相互促进、相辅相成的，复习时可将近几年的高考试题科学归类，联系教材，通过梳理相关知识点，讲究方法，归纳技巧，勇于号脉高考；因此在选做习题时，要听
招数四：把握重点，消除盲点，切实做好纠错
分析近几年的高考化学试题，重点其实就是可拉开距离的重要知识点，即疑点和盲点；要走出“越基础的东西越易出差错”的怪圈，除了思想上要予高度重视外，还要对作业、考试中出现的差错，及时反思，及时纠正；对“事故易发地带”有意识地加以强化训练是一条有效的途径。每一次练习或考试后，要对差错做出详尽的分析，找出错误根源，到底是概念不清原理不明造成的，还是非知识性的失误。对出现的差错要作记载，每隔一段时间都要进行一次成果总结，看看哪些毛病已“痊愈”，那些“顽症”尚未根除，哪些是新犯的“毛病”，从而不断消除化学复习中的疑点、盲点；然后因人而异的采取强化的纠错方式加以解决。这里就扼要介绍几种常见纠错做法，以供参考。
1、摘抄法：将纠错内容分类摘抄，在其题下或旁边加以注释；
2、剪贴法：将纠错题目从试卷上剪裁下来，按照时间、科目、类别分别贴在不同的纠错本上，并在题目下部或旁边加上注释；
3、在资料及试卷上纠错：有序整理资料及试卷，或按时间段、或按类别、或按科目地分门别类，加以注释；
4、将纠错还原到课本：将纠错点还原到课本上，在课本知识点相应处，用不同字符标记纠错点，同时在其下部或旁边或附一纸片，标出该点纠错题目位置、出处，错误原由及简易分析等内容。

常用的无机干燥剂
为了保持药品的干燥或对制得的气体进行干燥，必须使用干燥剂。常用的干燥剂有三类：一类为酸性干燥剂，有浓硫酸、五氧化二磷、硅胶等；第二类为碱性干燥剂，有固体烧碱、石灰和碱石灰（氢氧化钠和氧化钙的混合物）等；第三类是中性干燥剂，如无水氯化钙、无水硫酸镁等。常用干燥剂的性能和用途如下：
1、浓H2SO4：具有强烈的吸水性，常用来除去不与H2SO4反应的气体中的水分。例如常作为H2、O2、CO、SO2、N2、HCl、CH4、CO2、Cl2等气体的干燥剂。
2、无水氯化钙：因其价廉、干燥能力强而被广泛应用。干燥速度快，能再生，脱水温度473K。一般用以填充干燥器和干燥塔，干燥药品和多种气体。不能用来干燥氨、酒精、胺、酰、酮、醛、酯等。
3、无水硫酸镁：有很强的干燥能力，吸水后生成MgSO4.7H2O。吸水作用迅速，效率高，价廉，为一良好干燥剂。常用来干燥有机试剂。
4、固体氢氧化钠和碱石灰：吸水快、效率高、价格便宜，是极佳的干燥剂，但不能用以干燥酸性物质。党用来干燥氢气、氧气、氨和甲烷等气体。
5、变色硅胶：常用来保持仪器、天平的干燥。吸水后变红。失效的硅胶可以经烘干再生后继续使用。可干燥胺、NH3、 O2、 N2等
6、活性氧化铝（Al2O3）：吸水量大、干燥速度快，能再生（400 -500K烘烤）。
7、无水硫酸钠：干燥温度必须控制在30℃以内，干燥性比无水硫酸镁差。
8、硫酸钙：可以干燥H2 。O2 。CO2 。CO 、N2 。Cl2、HCl 、H2S、 NH3、 CH4等
由上述可知、对一些气体的干燥剂可作如下选择。

We are always hearing about road accidents, and when we are in the car we try to drive carefully. But, how many of us take the same degree of care in our homes? A large 36 will tell you the number of accidents that happened in the home is almost the same as those on the 37 . I don’t pretend to be 38 , but I’ve thought a lot about how and why these accidents happen and what we can do to 39 them.
One of the most common and most dangerous 40 at home accidents is wrong and careless use 41 electrical equipment. People will continue to use a loose plug or 42 out a plug without first turning off the 43 . In spite of warmng, one 44 carry an electric heater in to the bathroom when he is going to have a 45 . Sometimes on forgets to turn off the power 46 mending a lamp or something 47 . All this can cause accidents. So the 48 about anything that works by electricity is: Switch off before you 49 anything and don’t pretend you know when you actually 50.
If you’ve got 51 in th house, it’s always best to keep medicines of any kind out of their 52 . otherwise, they may be taken for candies or new kinds of drinds. When there are older eople living with you, you have to take particular 53 in a number of ways in order to make them 54 and happy.
55 , of course, is always a risk. So, remember to turn it off after cooking. Also, don’t forget to keep the children away from the cooker.

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
A
The sea has always interested man. From it he can get food, minerals, and treasure. For thousands of years, he could sail on it. But he could not go far beneath its surface.
Man wants to explore deep into the sea. However, he is not a fish. He must breathe air, so he can’t stay under the water’s surface for any length of time. To explore deep water, man faces even more dangers and problems.
A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases. He can wear a diving suit and have air pumped to him from above. He can carry a tank of air on his back and breathe through a nose and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea. His body is under great pressure.
When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles. The diver is then suffering from the bends. The bends can cause a diver to double yp in pain. They can even kill him.
56．On the whole, this passage is about ____.
A．special mixtures of gases in deep sea
B．the problems man faces in deep-sea diving
C．air pressure under the surface of sea water

A．is under great pressure
B．is just like that of a fish
C．suffers from the bends
D．weighs very little
58．The passage does not say so, but it makes you think that ____ .
A．deep- divers should be in good health
B．divers explore the deep sea only for treasure
C．diving under the water too quickly causes a kind of illness.
D．there is a special mixture of gases under the sea
59．Why does a diver get the bends?
A．He tries to do exercises under the water.
B．His diving suit weighs too much.
C．He comes to the surface too quickly.
D．The air in his blood is used up.

What kind of car will we be
driving in 2010? Rather different from the type we know today, with the next 20
years bringing greater change than the past 50．the
people who will be designing the models of tomorrow believe that environmental
problems may well accelerate the pace of the car’s development. Today they are

Their vision is of a machine with three wheels instead of four, electrically powered, environmentally clean, and able to drive itself along “intelligent” roads equipped with built-in power supplies. Future cars will pick up their fuel during long journeys from a power source built into the road, or store it in small quantities for travelling in the city.
Instead of today’s seating arrangements―two in front, two or three behind, all facing forward― the 2010 car will have a versatile interior with adults and children in a family circle.
This view of the future car is based on a much more sophisticated road system, with strips built into motorways to supply power to vehicles passing along them, cars will not need drivers, because computers will provide safe driving control and route finding. All the driver will have to do is say where to go and the computer will do the rest. It will become impossible for cars to crash into one another. The technology already exists for the car to become a true automobile.

Why isn’t a dollar worth as much as it used to be? One dollar is always worth the same amount, that is, 100 cents. But the value of a dollar is how much can buy. The value of money depends on the cost for living. Economists say that the cost of living is the money that a family must pay for the necessities of life such as food, housing or rent, clothes, and medical expenses. For many years now, the cost of living has increased greatly, so the value of the dollar has decreased. When a dollar has a low value, you cannot buy as many things with it.
No one fully understands why the cost of living keeps increasing, but economists believe that workers and producers can make prices go up. As workers earn more money, they have more money to spend, so they demand more goods. If there is a great demand for certain goods, the prices of these goods go up. At the same time, if there’s a shortage of goods, the prices also go up. For example, if everyone wants to buy more and more gas, the price of gas goes up. When companies with hold gas from buyers, they can also make the price of gas go up.
Families need to know what happens to their money. They need to make their income meet the cost of living, so many people plan a family budget. A budget is a list of monthly expenses. If your expenses add up to more than your income, you must find ways to save money. Maybe you’re spending too much on entertainment. Or if you’re spending too much on clothes; you may want to sew your own clothes. Budgeting helps you spend your money wisely as the cost of living increases.
71．What has troubled many families in the
A．A not-large-enough income.
B．Nothing is left over to put away.
C．The increasing cost of living.
D．A shortage of certain foods
72．_ ___ determines the value of the dollar.
A．The government B．The cost of living
C．The economist D．The bank
73．While the cost of living increases, the value of the dollar____ .
A．increases to B．decreases
C．neither increases nor decreases D．seldom decreases
74．When ____ , the prices go up.
A．demand exceeds supply B．supply exceeds demand
C．demand doesn’t exceed supply D．supply equals demand
75．Budgeting helps ____ .
A．one to make his income meet the cost of living
B．the government to battle the rising cost of living
C．merchants to produce more goods
D．the workers to earn more money

If you are worried about things and are under a lot of stress at work or school, then you are probably not sleeping well. Worry can keep you awake, tossing and turning in bed until the early hours of the morning when you eventually fall asleep. When you wake up, you don’t feel refreshed, but tired and worn out and unable to face a new day.
Dr. Henry Winkle, in a recent newspaper article entitled Stress and Sleep, indicates that _________ . Dr. Winkle says, “The more we worry, the less we sleep, the more we are unable to deal with stress. If we can find a way to get a good night’s sleep,” he adds, “we can often find the energy to deal with what’s worrying us”.
So, what is a good night’s sleep? Research shows that the amount of sleep which people need in order to keep healthy varies a lot. Seven hours in about the average amount, though strangely enough, sleeping longer often gives you a headache instead of making you feel more refreshed.
Dr. Winkle believes that preparing for sleeping is important. People who work late should try to give themselves a short break and do something restful before going to bed. This could be watching TV or listening to music. Doing some exercise earlier in the day should help you to feel physically as well as mentally tired. A bedtime drink can also help, but coffee or tea should be avoided as they contain caffeine and will keep you awake. “When you put the light out,” Dr. Winkle says, “concentrate on relaxing your muscles, working slowly up from your feet, and you’ll be asleep before you know it.”
