AKrakatau Volcano (喀拉喀托火山)is on a small island in Indonesia. It had been peaceful for about 200 years before it erupted (爆发)in 1883.The first signs of the activity of the volcano appeared in May 1883, when fire and smoke could be seen at the top of the mountain. Great noise could be heard even in Jakarta, a hundred miles away. Later the activity grew much greater. The peak (山顶)was covered with smoke and fire; the smoke at one time was seventeen miles high in the air. The lava—soft and hot rock—shot up into the air and rolled down the sides of the mountain.The mouth of the volcano was not at the peak of the mountain but on its side, close to the sea. As it grew bigger and bigger with the eruption, the sea water got into it. When the sea water reached the lava inside the volcano, it made the upper part of the lava colder and harder. And this sealed off(封住)the rest of the lava below. As the inside of the lava could not break through the seal, the pressure (压力)built up until the mountain blew up.The eruption of the volcano was followed by several earthquakes which brought about bad results. About 36, 000 people were killed and many towns and villages near the sea were completely destroyed by the great waves which the earthquakes caused.1. Give the correct order of the course of volcano eruption.①The peak was covered with smoke and fire.②Fire and smoke could be seen at the top of the mountain.③Great noise could be heard a hundred miles away.④The lava shot up into the air and rolled down the sides of the mountain.A. ①②③④B. ①③②④C. ②③①④D. ④①③②答案:C解析:细节理解题。
从文章第二段的描述可知顺序为②③①④。
2. What made Krakatau Volcano erupt?A. The sea water which went into the volcano.B. The lava.C. The pressure which was bigger and bigger.D. All of the above together.答案:D解析:细节理解题。
由文章第三段可知该火山爆发是A、B、C三项共同作用的结果, 并非由其中的一项原因造成的。
3. Where is the mouth of the volcano?A. At the peak of the mountain.B. On the side of the mountain near the sea.C. At the foot of the mountain.D. Inside the mountain.答案:B解析:细节理解题。
根据文章第三段第一句话“The mouth of the volcano was not at the peak of the mountain but on its side, close to the sea. ”可判断答案为B项。
B“Earthquake!” the word flashed in my brain. A roaring sound filled my ears. I tried to slide beneath my desk. The desk did a wild tap dance, slipping and sliding towards the centre of the room. I twisted my body and grabbed at the windowsill (窗沿) behind me, somehow kicking free of my dancing chair. I tried to stand. My legs skated away as if on a bucking escalator.My fingers shook, grasped the windowsill tightly. Somewhere through the roar sounded the terrified scream of some wounded animal. I looked behind me and tried to steady my gaze on the other kids but the scene was a dizzy nightmare. Some of the class were sitting in the middle of the room, surrounded by chairs and desks. One girl was screaming. A boy was trying to claw his way across the floor to the door in a crazy crawl.My grip froze me to the windowsill.I cried aloud, “I’m going to die. I’m going to die. Save me. I’m not ready to die. I’m not ready!”I hunched (弓起背部) forward on my knees and pressed my face against my clenched (紧握) fingers. I looked at the backs of my fingers and stupidly noticed the fragile pale hairs growing out of the pores (毛孔). The fingers would soon cease to exist. Somehow the impending horror of my death was too terrible to even cry about.Suddenly, I became aware that the rocking had ceased. Perhaps I wasn’t going to die.4. The roaring sound was made by.A. a wounded animalB. screaming peopleC. running childrenD. an earthquake答案:D解析:细节理解题。
由第一段前两句可知, the roaring sound应是发生地震时发出的声音。
5. When the writer clenched his fingers he was .A. afraidB. angryC. injuredD. impatient答案:A解析:细节理解题。
由倒数第二段可知, 作者握紧手时非常害怕。
6. Paragraph 2 describes the.A. injuries suffered by the writerB. effects of a bad nightmareC. disorder in the classroomD. writer’s fear of death答案:C解析:从文章第二段中所提到的孩子、桌子、椅子、屋子等均可说明这个地方是教室, 而且是一片混乱。
7. At the end of the passage there is a feeling of.A. panicB. hopeC. sorrowD. excitement答案:B解析:推理判断题。
从文章最后一句我们可以看出他可能死不了了, 应感觉有希望了。
8. The underlined word “ceased” in the last paragraph probably means “”.A. continuedB. lastedC. stoppedD. increased答案:C解析:词义猜测题。
由最后一句“Perhaps I wasn’t going to die. ”可推知, 那种摇晃已经停止了。
ceased与stopped的含义最接近。
CWhen newspapers and radios report the damage caused by a hurricane (飓风)called Hazel, girls named Hazel are probably played a joke on by others. To keep out of trouble, the Weather Bureau says, “Any resemblance(相似)between hurricane names and the names of particular girls is only accidental. ”Some women became angry because hurricanes are given their names, but many other women are proud to see their names make headlines. They don’t even care that they are the names of destructive storms. Because morewomen seem to like it than dislike it, the Weather Bureau has decided to continue using girls’ names for hurricanes.In some ways a hurricane is like a person. After it is born, it grows and develops, then becomes old and dies. Each hurricane has a character of its own. Each follows its own way through the world, and people remember it long after it has gone. So it is natural to give hurricanes names, and to talk about them almost as if they were alive.9. What happens to the girls named Hazel when hurricane Hazel is reported?A. They suffer from hurricanes.B. The Weather Bureau looks for them.C. Others often make fun of them.D. They can’t find boyfriends.答案:C解析:细节理解题。

Unit 3Computers(时间：100分钟分值：120分)第一部分阅读理解(共两节，满分35分)第一节(共10小题；每小题2.5分，满分25分)AWhen third and fourth graders in Cheryl Barber's class at Helena Flats Montessori School write stories about plants, they're not using pencils and paper, but rather iPads to take photos and type text.Nine-year-old Jenna Oilar held an iPad up to a bamboo plant.At the touch of the screen she took a photo.With her index finger and thumb she then changed it to fit a page in her group's book.Under the photo she typed in text.Students can use many free apps(应用程序), uploaded by their teacher, to help learning.The apps offer a wide educational games suitable for learning.To teach fluently, Barber plans to have students record themselves' reading.There are also advantages in using tablets with students who have disabilities or are learning a second language.Students can enlarge text, change fonts(字体), translate text to a different language or use audio to read text.Using mobile technology isn't new to Barber's classroom.Before the iPads, her students used laptops and the iPod touch.The apps don't work to students who are learning to count money, tell time, solve maths problems and spell as they will get immediate feedback if they are doing a problem incorrectly.Rather than traditional flashcards, Alex Puhl, 8, enjoys playing the game “Math Ninja” where he fights a robotic army by solving maths problems that pop up on the screen.Students can only use games loaded by their teachers.The iPads also show a user's history—when a student starts or stops a program.Student scores are e-mailed directly to Barber.Is third grade too early to introduce so much technology? Barber doesn't think so.“By 2015, third grade is expected to type a story all in one setting，” Barber s aid.What hasn't changed is that teachers still teach required curriculum(课程)．There still are pencils at desks, notebook paper, and yes, teachers' lectures and worksheets to fill out by hand.1．What can we conclude from the passage?A．The iPad is a real game changer in class.B．The iPad has side effects on students.C．The iPad brings convenience to teachers.D．The iPad is the cause of students' failure.2．What did Jenna Oilar do with an iPad?A．She was texting a message for her teacher.B．She was playing a computer game attentively.C．She was taking a picture of a bamboo plant.D．She was typing a letter to her parents.3．The benefits of iPads for students are that ________．A．they are free and programmed with funny gamesB．they are also suitable for children with disabilitiesC．they are timely uploaded by the school teachersD．they are only intended for learning languagesBComputer technology is still developing rapidly.The computer of the future will increase in value and performance while decrease in cost.It will become smaller, but faster and more powerful.It is possible to make some guesses about what the future of the computer will look like, based upon the types of technologies that are being developed now.A lot of progress has already been made in some of these new technologies, but some are still in their earliest stages and may not be ready for use for years.Two of the most interesting areas of computing that are currently being developed are quantum computing(量子计算) and nanotechnology(纳米技术)．Quantum computing is one possibility for the future of the computer that could make computers run far faster than even the quickest computers do today.Quantum computers could be able to do what modern supercomputers are unable to do by using transistors that are able to take on many statistics at the same time.Nanotechnology could also change the face of computing, by creating computers that could be very powerful, though they are tiny in size.These computers could be incorporated(并入) into everyday objects, including electrical appliances(电器), clothes and even the human body.We will beable to use computers in new and unimaginable ways.They will become a part of our lives rather than simply being a box that is used only for specific purposes such as work.Quantum computing and nanotechnology will be able to play new roles, which will make us live greener lives, as well as enjoy better health and happier lives.4．According to the text, quantum computing ________．A．has been put in use so farB．can make computers run by themselvesC．can reduce the cost of computersD．will work by using transistors5．The text is mainly about ________．A．what nanotechnology isB．what quantum computing isC．what the computer of the future is likeD．what future computers can bring us6．Which of the following best shows the structure of the text?(①＝Paragraph 1, ②＝Paragraph 2，…⑤＝Paragraph 5)A. B.D.CAlmost every day, we discuss the topic of health, especially for kids.But what is health? “Health” means eating well, getting enough exercise, and having a healthy weight.Let's read the following rules.They can help you stay healthy.①Eat a__variety__of foods, especially fruit and vegetables.We all know that eating fruit and vegetables can help us stay healthy, but many of us only eat our favourite foods.Remember that we can only get the nutrition(营养) we need by eating different kinds of food, especially fruit andvegetables.② Drink water and milk most often.Everyone knows that water is important.Besides that, kids need plenty of calcium(钙) to grow strong bones, and milk has a lot of it.Every day, you should drink at least three cups of milk (1300 milligrams of calcium), when you are 9 years old or older.You should also try to have less sugary drinks, like soda and coca.They include a lot of sugar.Sugar just includes calories, not important nutrition.③Listen to your body.When you are eating, notice how your body feels.When your stomach feels comfortably full, stop eating.Eating too much makes you feel uncomfortable.If you do it too often, it can make you unhealthy and fat.④ Limit(限制) screen time.What's screen time? It's the amount of time you spend watching TV, movies, and playing computer games.The more time you spend on these sitting-down activities, the less time you spend playing sports, like basketball, and doing other activities like bike riding and swimming.Try to spend no more than 2 hours a day on screen time.7．In this passage, “health” includes all of the following EXCEPT ________．A．eating wellB．doing more exerciseC．having a healthy weightD．wearing comfortably8．The underlined phrase “a variety of ” means “________”．A．a few ofB．a lot ofC．the rest ofD．all kinds of9．As kids, we should drink at least ________a day to grow strong bones.A．three cups of milkB．four cups of milkC．two cups of milkD．one cup of milk10．What's the main idea of the passage?A．How to eat healthily.B．Eating and playing are both important.C．Advice on staying healthy.D．Health is very important.第二节(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

2019-2020年高中英语人教版必修2 Unit 3 Computers period1 教案Warming upThis section is an introduction to the topic．It is to get the students thinking about the different ways computers can be made．Do this part of the lesson in pairs and as a speaking activity．Warming 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.Draw on the blackboard a diagram to illustrate the influence of the computer and the Internet over the school education．Below is a diagram you may like to use．Ask students to look at the diagram and consider, ”What changes have computers and the Internet brought to schools? What changes will they bring to schools in the future?”Ask the Ss to work in groups and to make a list of the possible changes they can think of．When most of the groups have their lists ready, the teacher can hold a class discussion．Write down the major changes the students think of under / beside the diagram．The teacher can add one or two changes that may affect their own teaching．For example, “Computers and the Internet can help busy parents contact teachers by email．”The teacher can end the task with a brief summary, or hold a further discussion to find out students' personal opinions about the changes．For example, ask them, “Do you like all these changes? Why and why not? What changes do you like / dislike?”Some information: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 othermetals. 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 InternetPeriod2-3 Pre-reading & ReadingPre-readingThis can be a continuation of the Warming Up．Let the students discuss the questions set out in the Student's Book．1. Questioning and answering What do you know about computer?●Electronic 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 device 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 programmable hardware component that is controlled b y internally stored programs and that can perform substantial computations (including arithmetic andlogic 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 automation 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 is 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, if 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.II. ReadingThis is the purpose of the reading and so it is important that the students learn to use all the clues in the text to help them understand the gist of what they are reading．So encourage them to look at the pictures and the heading and guess what the text might be about．Then ask the class to read the passage silently．Make sure the students have the chronology of the development of computers in their minds．Ask them:1. Listening and reading to the recording of the text WHO AM I?Turn to page 18 and listen and read to the recording of the text. Pay attention to the pauses, pronunciation and intonation of the native reader.2. Reading aloud and underlining expressionsNow we are to read the text once again and underline all the expressions in the text. Put them down into your notebook after class as homework.Collocations from WHO AM I?be gin as…, a calculating machine, be built as…, follow instructions from…, sound simple, at the time, a technological revolution, write a book, make…work, solveproblems, become huge, had artificial intelligence, go back to…, the size of…, go by, change size, become small and thin, get quick, stand there by oneself, be connected by…, share information by…, talk to…, bring…into…, deal with…, communicate with…, serve the human race3. Reading, identifying and settlingAttention, please! It is time to skim the text one more time and identify the difficult sentences. Try analyzing the structures of the difficult sentences and discuss them among your group members. You may also put your questions to me for help.Chat （online）（在线）聊天To chat is to talk about ordinary things that are not very important. You can chat to one person or to many people. People also use this word now for parts of the Internet where we can talk with many different people at the same time. Usually, you chat on the internet in a chat room or messaging service like AOL(American On-Line) Instant Messenger (AIM), Yahoo Messenger, or MSN Messenger.IV. Closing down by doing comprehending exercisesTurn to page 18 and in pairs do the comprehending exercises No. 1 and 2.

Warming up⑴ Warming 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?⑵ Warming up by learning some computer jargonsJargons are terms used by some special people. These are some of the computer jargons.⑶ Warming up by getting to know what a computer virus is. Computer viruses (病毒)are small software programs that are planned to spread from one computer to another and to do harm to computer operation.A virus might harm or wipe out data on your computer, using your e-mail program to spread itself to other computers.Viruses are most easily spread by e-mail messages. That is why it is important that you never open e-mail unless you know who it's from and you are expecting it.Viruses can be made to look like funny images, greeting cards, or audio and video files.Viruses also spread through downloads on the Internet. They can be hidden in software or other files or programs you might download.To help avoid viruses, it's essential that you have the latest updates and antivirus tools, stay informed about recent threats, and that you follow a few basic rules when you surf the Internet, download files, andopen attachments.2. Pre-reading by talking about how computer worksHow does a computer work?A computer has four main parts: the arithmetic and logic unit (ALU), the control unit, the memory, and the input and output devices (collectively termed I/O). These parts are interconnected by groups of wires.The control unit, ALU, registers, and basic I/O (and often other hardware closely linked with these) are collectively known as a central processing unit (CPU). Early CPUs were comprised of many separate components but since the mid-1970s CPUs have typically been constructed on a single integrated circuit called a microprocessor.3. Listening and reading to the recording of the text WHO AM I? Turn to page 18 and listen and read to the recording of the text. Pay attention to the pauses, pronunciation and intonation of the native reader.4.
