词数:287 完成时间:7分钟 难度:***
Americans are pound of their variety- and individuality, yet they love and respect few things more than a uniform. whether it is the uniform of an elevator operator or the uniform of a five-star general. Why are uniforms so popular in the United States?
Among the arguments for uniforms, one of the first is that in the eyes of most people they look more professional than civilian (百姓的) clothes. People have become conditioned to expect superior quality from a man who wears a uniform. The television repairman who wears uniform tends to inspire more trust than one who appears in civilian clothes. Faith in the skill of a garage mechanic is increased by a uniform. What easier way is there for a nurse, a policeman, a barber, or a waiter to lose professional identity (身份) than to step out of uniform ?
Uniforms also have many practical benefits. They save on other clothes. They save on laundry bills. They are tax- deductible ( 可减税的). They are often more comfortable and more durable than civilian clothes.
Primary among the arguments against uniforms is their lack of variety and the consequent loss of individuality experienced by people who must wear them. Though there are many types of uniforms, the wearer of any particular type is generally stuck with it, without change, until retirement. When people look alike, they tend to think, speak, and act similarly, on the job at least.
Uniforms also give rise to some practical problems. Though they are long-lasting, often their initial expense is greater than the cost of civilian clothes. Some uniforms are also expensive to maintain, requiring professional dry cleaning rather than the home laundering possible with many types of civilian clothes.
1. It is surprising that Americans who worship variety and individuality ___________.
A. still judge a man by his clothes
B. hold the uniform in such high regard
C. enjoy having a professional identity
D. will respect an elevator operator as much as a general in uniform
2. People are accustomed to thinking that a man in uniform ____________.
A. suggests quality work
B. discards his social identity
C. appears to be more practical
D. looks superior to a person in civilian clothes
3. The chief function of a uniform is to ___________.
A. provide practical benefits to the wearer
B. make the wearer catch the public eye
C. inspire the wearer's confidence in himself
D. provide the wearer with a professional identity
4. According to the passage, people wearing uniforms _____________.
A. are usually helpful
B. have little or no individual freedom
C. tend to lose their individuality
D. enjoy greater popularity
5. The best title for this passage would be ____________.
A. Uniforms and Society
B. The Importance of Wearing a Uniform
C. Practical Benefits of Wearing a Uniform
D. Advantages and Disadvantages of Uniforms
答案:
文章第一段提出制服在美国受欢迎的现象,第二段说了一个主要论点——制服的好处,第三段说的是实际 好处,第四段说的是反对的论点——制服的缺点,第五段说的是实际问题:
1.答案是B.第一段第一句yet转折后面就是答案:Hold...in regard和respect是同义转换:
2.答案是久答案对应在第二段,People ...expect superior quality...。认为穿制服的水平更高。D错在混淆了superior的目标,不是人,而是quality,所以不对:
3.答案是D.在第二段最后,提到制服的主要功能是什么:A是实际的好处,而不是主要功能。

篇7:高一数学必修1课件
一、内容与解析
(一)内容:对数函数的概念与图象
(二)解析:本节课要学的内容是什么是对数函数,对数函数的图象形状及画法,其核心是对数函数的图象画法,理解它关键就是要理解掌握对数函数的图象特点.学生已经掌握了指数函数的图象画法及特点,函数图象的一般画法,本节课的内容就是在此基础上的发展.由于它是研究对数函数性质的依据,是本学科的核心内容.的重点是对数函数的图象特点与画法,解决重点的'关键是利用函数图象的一般画法画出具体对数函数的图象,从而归纳出对数函数的图象特点,再根据图象特点确定对数函数的一般画法。
二、目标及解析
(一)教学目标:
1,理解对数函数的概念;掌握对数函数的图象的特点及画法。
2,通过具体实例,直观感受对数函数模型所刻画的数量关系;通过具体的函数图象的画法逐步认识对数函数的特征;
3,培养学生运用类比方法探索研究数学问题的素养,提高学生分析问题、解决问题的能力。
(二)解析:
1,理解对数函数的概念是来源于实践的,能从函数概念的角度阐述其意义;掌握对数函数的图象和性质,做到能画草图,能分析图象,能从图象观察得出对数函数的单调性、值域、定点等;了解同底指数函数和对数函数互为反函数,能说出它们的图象之间的关系,知道它们的定义域和值域之间的关系,了解反函数带有逆运算的意味;
2,通过具体的实例,归纳得出一般的函数图象特征,并能够通过图象特征得到相应的函数特征,培养学生的作图、识图的能力和归纳总结能力;
3,类比指数函数的图象和性质的研究方法,来研究对数函数,让学生认识到研究问题的方法上的一般性;同时,让学生认识到类比这一数学思想,即对相似的问题可以借鉴之前问题的研究方法来研究,有助于提高学生分析问题、解决问题的能力。
三、问题诊断分析
本节课容易出现的问题是:对数函数的图象特点的探究容易出现图象不对、归纳不全、有所偏差等情形。出现这一问题的原因是:学生作图能力、识图能力、归纳能力不强。要解决这一问题,教师要通过让学生类比指数函数图象和性质的探究,时时回过头看看之前是怎么做的,考虑了哪些问题,得到了哪些结论,让学生类比自主探究,必要时给予适当引导,让学生自主的得出结论,对于出错的地方要让学生讨论,教师做出适当的评价并最终给出结论。

Every person needs water and a diet of healthy foods. These foods should contain some fat, some fiber, a little salt and so on.
People need energy 16 . They eat different kinds of food which change into energy. The energy is 17 in calories. Even when you 18 , you are using energy – about 65 calories an hour. 19 you are at school, or walking home, your body is burning up 100 calories an hour. When playing football or basketball, you 20 be using 400 calories an hour. On Sports Day, during the relay race, you will use most of all, 21 as much as 650 calories an hour.
The Chinese diet is considered to be the healthiest in the world. It contains a lot of fruit and green vegetables. It is 22 in fiber and low in sugar and fat. The Chinese eat less sugar than many other countries in the world. That is 23 lots of people in China have healthy white teeth.
People in the Western world do not eat such healthy foods. They eat 24 fat and sugar and don’t take enough 25 . Because of this, they 26 weight very easily. Their diet contains a lot of fat in the 27 of potato crisps, potato chips, butter, cream and chocolate. They eat a lot of sugar which exist in cakes, soft drinks, 28 and so on.

第三节:阅读理解(共12小题;每小题2分,满分24分)
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,并把答案写在答题卷上。 A.
A car needs gas to run and your body also needs food to work for you. Eating the right kind of food is very important. It can keep your body strong, so take care of what you eat.
There are four main food groups altogether. The dairy products group has food like milk, cheese and sour milk. The other three groups are the meat and fish group, the fruit and vegetable group, and the bread and rice group. Each meal should have at least one food from all the four main groups. With all these food together you will be given enough energy during the day.
It is easy to get into bad eating habits. You may eat your breakfast in a hurry to get to school on time. Or you may not have time for a good lunch. It may seem easy to finish your supper with fish and chips all the time. But you will find yourself tired during these days and you can not think quickly.
Watching what you eat will help keep your body healthy and strong. It is also good to take some exercise. It will help you eat more if you take a walk or play games in the open air. Having a good eating habit with some exercise is the key to your health.
31. Which of the following diets do you think is the best one?
A. Eggs, tomatoes and chicken.B. Milk, bread, cabbages and beef.
C. Corn, fish, cream and pork. D. Rice, beancurd, apples, fish and chicken.
32. Which of the following is a good eating habit?
A. Going to school without any breakfast.B. Eating fish and chips for supper all the time.
C. Finishing your lunch in a very short time.
D. Having at least one food from all the four groups each meal.
33. In this passage the writer mainly tells us that ______.
A. every person needs food to grow wellB. taking exercise can keep your body strong
C. right kind of food with exercise will keep you healthy
D. enough energy helps people think more quickly
B.
Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food ,get enough sleep, and exercise regularly.
Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料).Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质) ,like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don't overeat. It is not helpful to be overweight.
Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little a amount of sleep may even result in a change of personality (人的个性).Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.
If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.
34. According to the passage,_________.
A .we should always keep fit
B. if we were healthy, we could spend our days in doing things with less sleep
C. one can eat a lot to stay in good shape
D. one needn't take any exercise if he is healthy
35.In order to keep good health, ___________ .
A. we should eat a lot of sweets B. one needs a large amount of fat
C. people should eat according to the foods nutrition D. we must try to sleep now and then
36. Eating more and sleeping less________.
A. can keep healthy B. is no good for you
C. gets you more energy D. will keep your personality
37.The writer explains ________in this passage.
A. how to eat B. the importance of doing exercise
C. how to keep healthy D. what to eat
38.The title of the article should be___________ .
A. Eating and Exercising B. How Vitamins Work in Man's Body
C. Staying Healthy D. Sleeping Well
C.
Isn't it astonishing how much time we spend talking about food? “Have you ever eaten …?” “What did you have for lunch?” and so on. And yet when you travel from one country to another, you will find that people have quite different feelings about food. People often feel that what they eat is normal (正常) and that what other people eat is strange or silly. In most parts of Asia, for example, no meal is complete without rice. In England, people eat potatoes every day. In the Middle East, bread is the main part of every meal. Eating like so many things we do, becomes a habit which is difficult to change. Americans like to drink a lot of orange juice and coffee. The English drink tea four or five times every day. Australians drink a great deal of beer, and the French drink wine every day.
The sort of meat people like to eat also differs from one country to another. Horse meat is thought to be delicious in France. In Hong Kong, some people enjoy eating snakes. New Zealander eat sheep, but they never eat goat meat. The Japanese don't like to eat sheep meat be-cause of its smell, but they enjoy eating raw fish (生鱼).
So it seems that although eating is a topic we can talk about for hours, there is very little common sense in what we say it. People everywhere enjoy eating what they have always eaten, and there is very little we can do to change our eating habits.
39. Which of the following is true according to the article?
A. All people have the same feeling about food.
B. In most parts of Asia, people usually have rice for meals.
C. People often consider other people to be strange or silly.
D. The topic people spend time talking about is bread and meat.
40. People in different countries .
A. drink the same sort of wineB. have the same eating habit
C. eat different kinds of meatD. have the same tea at different time within a day
41. The Japanese don't like to eat sheep meat .
A. because they dislike its smellB. because it is too expensive
C. because it is easy to go badD. because they think it will do harm to their health
42. English people drink tea four or five times a day .
A. because they get thirsty easilyB. because there is plenty of tea in Britain
C. because of their drinking habitD. because they have enough time to do so

篇9:高一物理必修1《圆周运动》课件
高一物理必修1《圆周运动》课件
一、教学目标
【知识与技能】
知道描述圆周运动快慢的两个物理量——线速度、角速度,会推导二者之间的关系。
【过程与方法】
通过对传动模型的应用,对线速度、角速度之间的关系有更加深入的了解,提高分析能力和抽象思维能力。
【情感态度与价值观】
在思考中体会物理学科严谨的逻辑关系,提高分析归纳能力,养成严谨科学的学习习惯。
二、教学重难点
【重点】
线速度、角速度的概念。
【难点】
二者关系的推导过程。
三、教学过程
环节一:新课导入
情景导入:课件展示生活中常见的圆周运动:
展示生活中的一些运动,引导找相似点:运动轨迹是一些圆,这种运动叫做圆周运动——引出课题。
环节二:新课讲授
过渡:学生列举生活中的圆周运动。
1.田径场弯道上赛跑的运动员的运动;
2.风车的转动;
3.地球的自转与公转;
4.自行车的前后轮、大小齿轮转动等。
研究物体的运动时,我们往往会提到物体的运动快慢。对于做直线运动的物体,我们用单位时间内的位移来描述物体的运动快慢.。
问题:对于圆周运动又如何描述它们的运动快慢呢?
(一)线速度
演示1:在台式电风扇的叶片上分别标记红、蓝两种颜色的点,到中间轴的距离不等。用手缓慢拨动叶片转动,让学生感受两点的运动,并用flash模拟。
让学生仔细观察,说出哪个点运动得快,你是怎么比较的。
讨论交流
两个点运动时间相同,但通过的弧长不相等,通过的弧长长的点运动得快。
总结:圆周运动的物体通过的弧长与所用时间的比值能够描述物体运动的快慢,我们把它称之为线速度。
定义:弧长l与通过这段弧长所用时间t的比值叫做线速度, 。(物体沿着圆周运动,并且线速度的大小处处相等,这种运动叫做匀速圆周运动)
说明:(1)线速度是瞬时速度。
(2)线速度是矢量,它既有大小,也有方向(在圆周各点的切线方向)。
(3)匀速圆周运动是一种非匀速运动,因为线速度的方向在时刻改变。
(4)单位:m/s.
(二)角速度
观察刚刚的flash,风扇叶片上的点在转动时,除了弧长发生了变化以外,还有什么变了?(与中点连线的`角度)
所以同样可以用半径转过的角度φ和所用时间t的比值来表示圆周运动的快慢。即角速度
定义: 说明:(1)对某一确定的匀速圆周运动而言,角速度ω是恒定的;
(2)单位:rad/s。
(三)推导二者关系
教师给出任务:尝试总结出线速度、角速度二者的关系。
学生独立进行推导,得出结论, , ,根据数学关系l=θr得:v=ωr.
环节三:巩固练习
给出问题场景:让学生观察自行车传动结构示意图中的大齿轮、小齿轮、后轮三个部分的转动,分析A、B、C三个点线速度、角速度的关系。
环节四:小结作业
除了线速度、角速度,还有一些可以用来描述快慢的物理量,如周期T、频率f,试着自己推导这些物理量之间的关系。
篇10:高一数学必修1教学课件
高一数学必修1教学课件
教学目标:
(1) 了解集合、元素的概念,体会集合中元素的三个特征;
(2) 理解元素与集合的“属于”和“不属于”关系;
(3) 掌握常用数集及其记法;
教学重点:
掌握集合的基本概念;
教学难点:
元素与集合的关系;
教学过程:
一、引入课题
军训前学校通知:8月15日8点,高一年级在体育馆集合进行军训动员;试问这个通知的对象是全体的高一学生还是个别学生?
在这里,集合是我们常用的一个词语,我们感兴趣的是问题中某些特定(是高一而不是高二、高三)对象的总体,而不是个别的对象,为此,我们将学习一个新的概念--集合(宣布课题),即是一些研究对象的总体。
阅读课本P2-P3内容
二、新课教学
(一)集合的有关概念
1. 集合理论创始人康托尔称集合为一些确定的、不同的东西的全体,人们
能意识到这些东西,并且能判断一个给定的东西是否属于这个总体。
2. 一般地,我们把研究对象统称为元素(element),一些元素组成的总体叫集合(set),也简称集。
3. 思考1:判断以下元素的全体是否组成集合,并说明理由:
(1) 大于3小于11的偶数;
(2) 我国的小河流;
(3) 非负奇数;
(4) 方程的解;
(5) 某校2007级新生;
(6) 血压很高的人;
(7) 著名的数学家;
(8)平面直角坐标系内所有第三象限的点
(9) 全班成绩好的学生。
对学生的解答予以讨论、点评,进而讲解下面的问题。
4. 关于集合的元素的特征
(1)确定性:设A是一个给定的集合,x是某一个具体对象,则或者是A的元素,或者不是A的元素,两种情况必有一种且只有一种成立。
(2)互异性:一个给定集合中的`元素,指属于这个集合的互不相同的个体(对象),因此,同一集合中不应重复出现同一元素。
(3)无序性:给定一个集合与集合里面元素的顺序无关。
(4)集合相等:构成两个集合的元素完全一样。
5. 元素与集合的关系;
(1)如果a是集合A的元素,就说a属于(belong to)A,记作:a∈A
(2)如果a不是集合A的元素,就说a不属于(not belong to)A,记作:aA
例如,我们A表示“1~20以内的所有质数”组成的集合,则有3∈A
4A,等等。
6.集合与元素的字母表示: 集合通常用大写的拉丁字母A,B,C...表示,集合的元素用小写的拉丁字母a,b,c,...表示。
7.常用的数集及记法:
非负整数集(或自然数集),记作N;
正整数集,记作N*或N+;
整数集,记作Z;
有理数集,记作Q;
实数集,记作R;
(二)例题讲解:
例1.用“∈”或“”符号填空:
(1)8 N; (2)0 N;
(3)-3 Z; (4) Q;
(5)设A为所有亚洲国家组成的集合,则中国 A,美国 A,印度 A,英国 A。
例2.已知集合P的元素为, 若3∈P且-1P,求实数m的值。
(三)课堂练习:
课本P5练习1;
归纳小结:
本节课从实例入手,非常自然贴切地引出集合与集合的概念,并且结合实例对集合的概念作了说明,然后介绍了常用集合及其记法。
