Ⅰ.阅读理解AAll over the world mothers and fathers teach their children manners.Other children may have manners that are not like yours.There are all kinds of manners.Many years ago，children who had good manners were seen and not heard.They kept quite quiet if grown-ups were talking.Today，well-mannered children have more freedom.Sometimes good manners in one place are bad manners in other places.Suppose you are a visitor in the land of Mongolia.Some friends ask you to eat with them.What kind of manners do they want you to have？They want you to give a loud “burp(打嗝)”after you finish eating.Burping would show that you like your food.In some countries，if you give a loud burp，you are told to say “Excuse me，please.”In many places people like to eat together.But in some parts of Polynesia，it is bad manners to be seen eating at all.People show good manners by turning their backs on others while they eat.What are manners like in an East African town? The people try not to see you.They are being polite.You may see a friend.He may not see you at all.If you are polite，you will sit down beside him.You will wait until he finishes what he is doing.Then he will talk to you.Suppose you visit a friend in Arabia.You should walk behind the other tents until you come to his tent.If you pass in front of the other tents，you will be asked into each one.The people will ask you to eat with them.And it is bad manners if you say no.Manners are different all over the world.But it is good to know that all manners begin in the same way.People need ways to show that they want to be friends.[语篇解读]本文主要介绍了世界上一些地方的礼仪。
1．How did polite children behave?A．By looking into adults' eyes while talking.B．By keeping silent while adults were talking.C．By slipping into the house without being heard.D．By not opening their mouths until spoken to.解析：细节理解题。
根据第二段的第二句“They kept quite quiet if grown-ups were talking.”可知，过去，在大人们说话时，儿童保持沉默是一种礼貌的行为。

根据第三段的最后两句“The people will ask you to eat with them.And it is bad manners if you say no.”可知，接受阿拉伯人一起吃饭的邀请是礼貌的行为。
答案：D3．What can we infer from the text?A．Hear much，speak little.B．Love me，love my dog.C．When in Rome do as the Romans do.D．Do what you ought to and come what can.解析：推理判断题。
根据全文内容尤其是最后一段的第一句“Manners are different all over the world.”可推知，礼仪因地域而各有不同，因此最好的做法是入乡随俗。

3 Computers李仕才【阅读理解插花】I am a writer. I spend a great deal of my time thinking about the power of language—the way it can evoke(唤起)an emotion, a visual image, a complex idea, or a simple truth. Language is the tool of my trade. And I use them all—all the English I grew up with.Born into a Chinese family that had recently arrived in California, I’ve been giving more thought to the kind of English my mother speaks. Like others, I have described it to people as “broken”English. But I feel embarrassed to say that. It has always bothered me that I can think of no way to describe it other than “broken”, as if it were damaged and needed to be fixed, as if it lacked a certain wholeness. I’ve heard other terms used, “limited English”, for example. But they seem just as bad, as if everything is limited, including people’s perceptions(认识)of the limited English speaker.I know this for a fact, because when I was growing up, my mother’s “limited”English limited my perception of her. I was ashamed of her English. I believed that her English reflected the quality of what she had to say. That is, because she expressed them imperfectly her thoughts were imperfect. And I had plenty of evidence to support me: the fact that people in department stores, at banks, and at restaurants did not take her seriously, did not give her good service, pretended not to understand her, or even acted as if they did not hear her.I started writing fiction in 1985. And for reasons I won’t get into today, I began to write stories using all the English I grew up with: the English she used with me, which for lack of a better term might be described as“broken”, and what I imagine to be her translation of herChinese, her internal(内在的)language, and for that I sought to preserve the essence, but neither an English nor a Chinese structure. I wanted to catch what language ability tests can never show: her intention, her feelings, the rhythms of her speech and the nature of her thoughts.【文章大意】本文主要记叙了作者在不同时期对母亲所使用的语言的不同看法。

My mother has always lived by some simple rules:Go to church every Sunday,help people in need,and don’t worry about unchangeable things.These simple rules have allowed her to live a content life,and in doing so,she sets an example for her children to follow.However,I had broken all of these rules by the time I set off for college.It was September,and I should have been ecstatic as I stood on my college campus saying goodbye to my parents and embarking my new independent life.However,I was just quietly crying.I had never been away from home without family.My mom hugged me,“Little girl,we’ll come back to get you next weekend and you can come home for a visit!”My homesickness made my freshman year in college difficult,and I comforted myself by throwing myself into my academics.I spent all my time studying,including weekends when everyone else attended parties.I had always been a good student.I would not settle anything but an A,and when I got a 4.0 my first semester,a frie nd said to me,“That’s great,but you can only go down from there!” Suddenly,I was more driven than ever.My mom was worried about my social life.She was happy that I got good grades but had always told me there was more to life.What about faith?What about helping others?She encouraged me to go to church.She believed that weekly attendance was the answer to my pathetic social situation.Sometimes,I find myself being critical (批评的) of my mother’s simple ways.It’s difficult with busy schedules to go to church every Sunday.And while I admire my mom’s ability to help anyone in need,I complain that I do not have as much time as I wish to follow her example.Her simple rules have served her well,and though I don’t follow them as much as I should,they are there like a beacon(灯塔),calling for me to follow.1.The underlined word “ecstatic” in Paragraph 2 probably means____.A.tearyB.excitedC.homesickD.sad2.What can we infer from the third paragraph?A.The author didn’t like any social activities.B.The author was angry with what her friend said.C.The author had a difficult time learning in college.D.The author couldn’t adapt to university life at first.3.What is the author’s opinion about her mother’s life rules?A.She values the rules because they are guiding in her life.B.She ignores the rules because they are meaningless to her.C.She supports the rules because they are suitable for her.D.She disapproves the rules because they are difficult to follow.参考答案：1.B; 2.D; 3.A解析：作者母亲的生活法则虽然简单,但却蕴含人生智慧,就像灯塔,指引作者在人生道路上前进。

必修2 Unit 3 Computers电脑晨读·记忆ComputersThe goal of early calculating machines was to simplify difficult sum s. But with the help of new technology, electronic chips replaced tubes and a revolution of artificial intelligence has arisen. From then on, the appearance of computers totally changed our lives. They can not only download information from the web when connected by the network or mobile phone signals, but also solve different types of logical problems. With operators as their coaches, they can even control rockets to explore the moon and instruct androids with the human race’s characters to mop floors and watch over your naughty niece. Anyhow, computers are so helpful that they do bring happiness.However, computers are easily attacked by viruses. This reality has become a hard-to-deal with-problem. As a result, computers are dangerous in a way. So, personally, I worry about their universal applications in some fields, such as finance.电脑早期计算机器的目的是简化比较难的计算.但是在新技术的帮助下，电子芯片代替了电子管，一场人工智能革命由此掀起.从那时起，电脑的出现完全改变了我们的生活，它们不仅能在网络或移动电话信号的连接下从网上下载信息，而且可以解决各种类型的逻辑问题.在操作员的教练下，它们甚至还可以控制火箭探索月球，指导具有人类性格的机器人擦洗地板和照顾你调皮的侄女.不管怎么说，电脑都是如此的有用，以致的确给人们带来了快乐.然而，电脑很容易受到病毒的攻击，这一现实已经成为一个难以处理的难题，结果，电脑在某种程度上是很危险的.因此，就个人而言，我很担心电脑在某些领域，例如金融方面的广泛应用.I.单词盘点1.__________(vt.) 计算→__________(n.) 计算；盘算；估计→__________(n.) 计算器2.__________(adj.) 普遍的；通用的；宇宙的3.__________(vt.) 简化→ _________(adj.) 简单的→ _________(n.) 简单化；单纯化4.__________(n.) 总数；算术题；金额5.__________(n.) （电脑）操作员；接线员→ _________(v.) 操作；做手术→ _________(n.) 操作；手术6.__________(adj.) 合逻辑的；合情理的→_________(adv.) 逻辑上；合逻辑地；有条理地7.__________(n.) 工艺；科技；技术II.短语回顾1.从……时起__________________2.结果__________________3.如此……以致于__________________4.在某种程度上__________________5.在……的帮助下__________________6.处理；安排；对付__________________7.看守；监视__________________8.弥补；化妆；编造；构成__________________ III.句式扫描IV.小试牛刀Ⅰ.单词填空1.Friendship is a(n)________________(universe) key to be able to open everyone's heart.2.I hope you will enjoy the book and find ideas in it to____________(simple) your life.3.She was once described as the most_______________(intelligence) woman in America.4.His dream of opening a restaurant became a(n)___________(real) in 1994.5._______________ (person)，I'm content with what you did.6.I cannot___________(total) agree with you，but I think what you said just now is partly reasonable.7.I think______________(happy) depends on our attitudes to life.8.You never told me why you made an ________________ (apply) for that position while you had had a good one.9.However, we should always bear this in mind: don't judge a person by his_______________(appear).10.The______________（solve) to making a right choice about your future is following your own heart.Ⅱ.短语填空1.The doctors and nurses_________________the seriously wounded worker day and night.2._________________computers，it is now easy to deal with and share information.3.They are friends，but they have little_________________.4.I think that the work is well done_________________.5.With time_________________，computers are becoming more and more popular.6.Don't get discouraged by setbacks；we are new to the work__________________.7._______________，you can deal with these problems on your own.8.He______________most of his money to charity after the meeting.9.I think we should work out a strategy to__________________this situation.10.Saying you are sorry won't_________________for the damage of breaking the vase.Ⅲ.单句填词1.He rushed out of the room__________I said a word.2.It ___________her ten years before she paid off her debts.(take)3.As time____________by,our country will become more and more powerful.(go)4.As time____________by, they became good friends and often sent e-mails to each other.

必修2 Unit 3 Computers李仕才一、阅读理解If you want to slow aging, you might want to eat less. This finding is good news---if you were a mouse. The researchers studied mice, not people.John Price and other researchers studied two groups of mice. One group was able to eat as much as it wanted. The researchers limited what the mice in the other group ate. Their diet had 35 percent fewer calories than the first group of mice.Price says the mice with the diet restrictions were “more energetic and suffered fewer disea se.” They were not just living longer but seemed to stay younger for a longer period of time.The researchers found that fewer calories slow down a natural mechanism in cells called ribosomes. Price explains that ribosomes are responsible for making important proteins in the cells. But with fewer calories, they slow down. This gives the cells more time to repair themselves.The researchers say ribosomes use from 10 to 20 percent of the cell’s energy to make those proteins. Price wrote that “because of this,it is impractical to destroy an entire ribosome” when it starts to break down. However, “repairing individual parts of the ribosome on a regular basis enables ribosomes to continue producing high quality proteins for longer than they would otherwise. This top quality production, in turn, keeps cells and the entire body functioning well.”Price said, “ribosome is a very complex machine, like a car.” They need “maintenance to replace the parts that wear out the fastest. When tires wear out,” he explained, “you don’t throw the whole car away and buy a new one. It costs less to replace the old tires.”“Food,” he said, “isn’t just material to be burned---it’s a signal that tells our body and cells how to respond.” Price said the findings help to explain how exac tly our bodies age. And this may “help us make more educated decisions about what we eat.”1.What can we know about the mice with limited calories from the study?A. They can keep healthy easilyB. They need more energy to be activeC. They can look younger than they areD. They will live a longer life like humans2.What will happen to ribosomes if there are fewer calories?A. They will completely break downB. They make proteins in the cells slowlyC. They will produce high quality proteins moreD. They may need more time to repair themselves3.Price explained the ribosomes’ role of repairing themselves by _________.A. telling a storyB. listing basic dataC. making comparisonsD. experimenting on mice4.What does the text mainly deal with?A. Food decides how long you liveB. Can you slow down your aging process?C. Eating less may help you live longerD. Should your diet be reduced for your health?【文章大意】本文是一篇说明文。

Unit 3 Computer 教学案Part One: Teaching Design (第一部分：教学设计)Period 1: A sample lesson plan for reading(WHO AM I？)AimsTo talk about computerTo read about computerProceduresI. Warming upWarming up by talking about computerLook at the pictures on page 17. What are they？What do they have in common？Yes，they are computers. Then what is a computer？A computer is a machine which stores knowledge in its memory and does calculations on that knowledge. This knowledge is stored in symbols；it is called data. A computer usually has a monitor to show results. However，some computers can speak；these computers can be used for voice mail.计算机室A computer frequently requires a boot device. The boot device contains the computer’s operating system and data. Computer programs can be installed onto a computer. Some people think that computers are less useful if they do not have access to the Internet. They think this because the Internet allows the computers to send and receive data and email across the world.曙光3000巨型计算机A computer is now almost always an electronic device. It usually contains materials which are toxic；these materials will become toxic waste when disposed of. When a new computer is purchased in some places，laws require that the cost of its waste management must also be paid for. This is called product stewardship.In some countries old computers are recycled (melted down) to get gold and other metals. This is dangerous，because this procedure releases the toxic waste into the water and soil.Computers become obsolete quickly. Very often they are given away and new ones replace them within two or three years. This makes the problem worse. Computer recycling is thus common. Many projects try to send working computers to developing nations so they can be re-used and will not become waste as quickly.Computer jargon 计算机行话Computer jargon means words to do with computers and surrounding topics. Knowing what these words mean can help you know more about computers. Some people use these words to impress other people (Also known as buzzwords).Examples of jargon:Bit - The smallest data unit，can either be a “0.” or a “1.”.Byte - unit of data. See also Kilobyte，Megabyte，Gigabyte and NibbleCPU –Central Processing Unit，Another name for processorData - Information stored on a computerDisk - A place to store data.Email - Electronic mail.GHz - Gigahertz. Used often incorrectly to describe the speed of a processor. But with some 2.4 GHz processors faster than 3.6 GHz ones，it is clear that it is just a salesman trick.Load - Get data from a diskNibble - Half a ByteSave - Put data on a diskRAM – random-access memory(随机存取存储器)，the more the better.USB - Universal Serial Bus(通用串行总线，一种简化了插接多种附件的薄型插座)WWW - World Wide Web，part of the InternetII. Pre-reading1. Questioning and answering---What do you know about computer？●Elect ronic machine capable of performing calculations and other manipulations of various types of data，under the control of a stored set of instructions. The machine itself is the hardware；the instructions are the program or software. Depending upon size，computers are called mainframes，minicomputers，and microcomputers. Microcomputers include desk-top and portable personal computers.●A multi-function electronic device that can execute instructions to perform a task.●A devi ce that accepts information，processes it，and supplies an output. A computer usually contains memory，a control unit，arithmetic and logical units，and a means for input and output.●a programm able hardware component that is controlled by internally stored programs and that can perform substantial computations (including arithmetic and logic operations) without human intervention. A computer typically consists of one or more processing units，memory units，and associated peripheral input and output devices.●Related to au tomation and electronic data processing. The Library of Congress commonly classes most computer-related books in HF5548，QA75-76，Z52，T385，and some TK ranges.●a machine for performing calculations automaticallycalculator: an expert at calculation (or at operating calculating machines)●A computer i s a device or machine for making calculations or controlling operations that are expressible in numerical or logical terms. Computers are constructed from components that perform simple well-defined functions. The complex interactions of these components endow computers with the ability to process information. If correctly configured (usually by，programming) a computer can be made to represent some aspect of a problem or part of a system. If a computer configured in this way is give2. Discussing and sharing---How have computers changed our lives？Someday soon，i f you haven’t already，you’re likely to plug into the computer network nation growing in our midst. Computer terminals，or small computers connected via modem (a modulator/demodulator circuit for encoding/decoding computer chatter) to ordinary telephone lines，should be as ubiquitous as the telephone itself. They’re a much more useful and humane tool than the phone，and with corporate America behind them the networks will be everywhere----changing our lives more than any technology since the automobile.Joining a computer network is the same as joining a community. Small systems are like villages，where new members are formally welcomed. The larger networks，the Source and CompuServe，for example，are cities-anonymous，full of life and events，but difficult to fit into.III. Reading1.

Writing a letterSuppose you are an android. What would say to a spoiled child who would not do his homework？Write a letter to the boy.AndroidAn android is an artificially created being that resembles a human being. The word derives from Greek Andr- ‘man，human’ and the suffix-eides used to mean ‘of the species，kind，alike’ (from eidos ‘species’).The word droid，a robot in the Star Wars universe，is derived from this meaning. Some people maintain that，etymologically，the word android means resembling a male human and that a robot resembling a woman should logically be called a gynoid for sexist language to be avoided；however，this word is not commonly used.Unlike the terms robot (a mechanical being) and cyborg (a being that is partly organic and partly mechanical)，the word android has been used in literature and other media to denote several different kinds of man-made，autonomous creations:a robot that closely resembles a humana cyborg that closely resembles a humanan artificially created，yet primarily organic，being that closely resembles a humanAlthough essentially human morphology is not the ideal form for working robots，the fascination in developing robots that can mimic it can be found historically in the assimilation of two concepts: simulacra (devices that exhibit likeness) and automata (devices that have independence).The term android was first used by the French author Mathias Villiers de l'Isle-Adam (1838-1889) in his work Tomorrow’s Eve，featuring a man-made human-like robot named Hadaly. As said by the officer in the story，“In this age of Realien advancement，who knows what goes on in the mind of those responsible for these mechanical dolls.”Part Two: Teaching Resources (第二部分：教学资源)Section 1: A text structure analysis of WHO AM I？I. Type of writing and summary of WHO AM I？Type of writingThis is a piece of narrative writing.Main idea of the passage Beginning as just a calculating machine in 1642 inFrance，the computer has been experiencingimprovement again and over again over 300years ormore，which has not only made it more beautiful andintelligent but also changed man’s life a great deal！Topic sentence of 1stparagraphI began as a calculating machine in 1642 in France.Topic sentence of 2nd paragraphNo one could recognize me after I got my new transistors in the 1960s.II. A chain of events showing the development of computera calculatin g machine in 1642 in France → an Analytical Machine in 1822 → a “universal machine.” in 1936 → the size of a large room → made smaller and smaller → getting new transistors in 1960s→ clever and quicker → a network in the early 1960s → talking to humans using BASIC in the early 1960s → brought into people’s homes in 1970s → Internet III. A retold version of the text WHO AM I？I，the computer，was a calculating machine in 1642 in France. Then Iwas built as an Analytical Machine in 1822，which was a technological revolution. I became a “universal machine” in 1936 to solve any mathematical problem. I was not very big at first then I became huge，the size of a large room before I was made smaller and smaller.Getting new transistors in 1960s I became clever and quicker. I was connected with other computers and turned out to part of a network in the early 1960s. Then I began talking to humans using BASIC in the early 1960s. In 1970s I was brought into people’s homes，and came the Internet.Section 2: Background information computersI. How Do Computers Work？Computer BasicsTo accomplish a task using a computer，you need a combination of hardware，software，and input.Hardware consists of devices，like the computer itself，the monitor，keyboard，printer，mouse and speakers. Inside yourcomputer there are more bits ofhardware，including themotherboard，where you wouldfind the main processing chipsthat make up the centralprocessing unit (CPU). Thehardware processes thecommands it receives from thesoftware，and performs tasks or calculations.Software is the name given to the programs that you install on the computer to performcertain types of activities. There is operating system software，such as theApple OS for a Macintosh，or Windows 95 or Windows 98 for a PC.There is also application software，like the games we play or the tools weuse to compose letters or do math problems.You provide the input. When you type a command or click on an icon，you are telling the computer what to do. That is called input.How They Work TogetherFirst，you provide input when you turn on the computer. Then the system software tells the CPU to start up certain programs and to turn on some hardware devicesso that they are ready for more input from you. This whole process iscalled booting up.The next step happens when you choose a program you want to use.You click on the icon or enter a command to start the program. Let’s usethe example of an Internet browser. Once the program has started，it is ready for your instructions. You either enter an address (called a URL，which stands for Uniform Resource Locator)，or click on an address you’ve saved already. In either case，the computer now knows what you want it to do. The browser software then goes out to find that address，starting up other hardware devices，such as a modem，when it needs them. If it is able to find the correct address，the browser will then tell your computer to send the information from the web page over the phone wire or cable to your computer. Eventually，you see the web site you were looking for.If you decide you want to print the page，you click on the printer icon. Again，you haveprovided input to tell the computer what to do. The browsersoftware determines whether you have a printer attached to yourcomputer，and whether it is turned on. It may remind you to turnon the printer，then send the information about the web page from your computer over the cable to the printer，where it is printed out.II. TelevisionOld portable televisionA television (also TV or telly) is a device (tool) with a screen that receives broadcast signals and turns them into pictures and sound. The word “television” comes from the words tele (Greek for far away) and vision (seeing).Usually a TV looks like a box. Older TVs had large wooden frames andsat on the floor like furniture. Newer TVs became smaller so they could fiton shelves，or even portable so you could take it with you wherever youwent. The smallest TVs can fit in your hand. The largest TVs can take up awhole wall in your house，and may sit on the floor，or be just a large flat screen that can be mounted on the wall. Many TVs are now made in wide screen shape like movie theatre screens，rather than old，more square TVs.A television has an antenna (or aerial)，or it has a cable. This gets the signal from the air，or cable provider. TVs can also show movies from DVD players or VCRs. TVs can be connected to computers and game consoles，usually through a kind of socket called “SCART”.III. Web or World Wide WebThe World Wide Web is the part of the Internet that contains web sites and web pages.It is not used to describe WebPages that are used offline where net services are not available，or no computer network exists - such as Wikipedia on CD. In this case no real physical site exists other than the place where the computer is. Blog and Wiki capabilities will also not be available because these require a communication with other computers.IV. RadioRadio is a communications invention. Though originally used tocommunicate between two people，it is now used to listen to music，news，and people talking. Radio shows were the predecessor to TV programs.V. DVDDVD most commonly stan ds for “digital versatile disk”. It can playvideo that is of a higher quality than a VHS tape.VI. Two kinds of DVDThey can also hold 4.7 GB of information as opposed to the 700 MB that a CD can hold. A plus of using a DVD for a video is the ability to have interactive menus and bonus features such as deleted scenes and commentaries.VII. EmailEmail (electronic mail) is a message，usually text，sent from one Internet user to another.Email is quicker than snail mail(mail) when sending over long distancesand is usually free. To send or receive an email，a computer with amodem and telephone line connected to the Internet，and an emailprogram are required. Email addresses are generally formated like this:login@server.(com or fr or org or uk or other).Some companies let you send and receive email for free from a website. Gmail，Hotmail and Yahoo！do this.VIII. HumanHere are two humans.A man is on the left and a woman is on the right. A human or human being is a person，like you. A male human is a man，a female human is a woman. If you think about all humans in the whole world，they are called humanity. In the past，people have also used man and mankind to mean all humans.Humans are called Homo sapiens by scientists. Humans are an animal species that belongs to the group called primates. Monkeys are primates too，but the primates most like people are gorillas and chimpanzees. Most scientists think that chimpanzees and humans came from a common ancestor by what is called evolution. Other animals even more like humans than chimpanzees once lived too，but they are now extinct.Human rights are those things that everyone deserves and the way they should be treated by other people.Section 3: Words and expressions from Unit 3 Computerscommonn. 1. an area of grassland with no fences which all people are free to use or a piece of open land for recreational use in an urban area (常用于专有名词中): Every Saturday Jean went riding on the village common. Harlow Common is very beautiful in winter.哈洛公园在冬天时风景很美。
