a.Help the students learn how to express their own opinions and find out truth through their own analysis.b.Guide the students to write the news clearly and pithily.Teaching methods 教学方法

Cooperative learning;task-based method.Teaching aids 教具准备 A computer and a projector.Teaching procedures ＆ ways教学过程与方式 Step Ⅰ Lead-in T: From the listening part we did yesterday we know there is something that is very important in finding out the truth.What is that? S: Eyewitness.T: Very good.Now imagine you are the organizer of a local fishing competition.A person tells you he / she had caught a fish which is the size of a small car.It will win him / her first prize at the competition.But an eyewitness says he / she cheated.He saw the fisherman buying it at a fish shop.Do you believe the eyewitness or the fisherman? Give your reason(s).I will give you eight minutes to think it over.Eight minutes later.T: OK.Time’s up.Who would like to represent your opinions?

S: Let me try.If I am the organizer, I would find out the truth no matter what they say.I will go to the fish shop where the fisherman had bought the fish according to the eyewitness.This is the best way to find out the truth I think....Step Ⅱ Speaking Task

Let the students work in groups of four to discuss the situation in Ex.2 on page 67 and then fill in the chart below.After that, let them role-play the situation.A sample dialogue: TV — CCTV Newsman / Newswoman F — Fisherman R — Reporter of Local Evening News E — Eyewitness TV: Good evening.It is lovely to be with you and to-night we have a very special story.It’s about a very large and rare fish that was caught during a fishing competition.And who is sitting here tonight is the fisherman who caught it.Good evening.F: Good evening.TV: Can you tell your story to the audience? F: OK.It was quite by accident.I went to the river early that morning.There was no one else.I threw my fishing line into the water and was amazed to find that immediately I had a bite on the line.It was this wonderful fish.So, of course, I pulled it out of the water quickly.TV: And was it the largest fish caught so far? F: Yes, indeed.TV: But an eyewitness has said that he saw you buying this fish in a fish shop.F: Well, I think that must have been a mistake.This is my fish.I caught it and it belongs to me.I can’t understand why someone would make up such a story.TV: Well, we’ll see.Let’s go to our reporter.He’s talking to the eyewitness who saw the whole thing.R: Hello there.I’m right by the fish shop and with me is Zhang Xia who saw the fisherman buy the fish.Now please tell us what happened? E: I saw the fisherman go into the shop and come out with this large, rare fish.When he went into the shop he had nothing at all.Really!

R: Did you follow him? E: Yes, because I thought it was a little strange.When I got close to the river I saw him showing his fish to the other fishermen.Then he went to the judges and they weighed his fish and told him it was the largest so far.R: Goodness.So you think he cheated? E: Yes, I think so.R: Wow!I must return you to the studio.TV: Well, what do you have to say about that? F:...It’s a lie!He has a friend who’s also taking part in this competition.I think he just wants him to win.TV: We can settle this right away.All we have to do is to go to the fish shop and ask the shopkeeper if he recognizes you or not....Step Ⅲ Writing Task

T: Now write the story as a newspaper article.List the facts and the opinions that go with them.Write about each fact and then write about the opinion.Try to follow the model on page 68 and make the news clear and pithy.At the same time please pay attention to the following: State the situation of the story in Paragraph 1;Set out what happened clearly in Paragraphs 2 and 3;State how the story ended and your opinion on what happened in Paragraph 4.Allow the students enough time to work on their writing.A sample version: Fish Story Today is the city’s annual Fathers’ Day Fishing Competition.Mr.Thompson took part in the fishing competition.He presented a very large and rare fish as big as a small car.Mr.Thompson said, “It was quite by accident.” “I had a bite on the line.It was this wonderful fish.So, of course, I pulled it out of the water very quickly.” He added.However, an eyewitness said he had seen Mr.Thompson earlier in the day buying fish at the fish market.He said, “I saw the fisherman go into the shop and come out with

this large, rare fish.” “Then he went to the judges and they weighed his fish and told him it was the largest so far”, said the witness.Mr.Thompson finally admitted he had bought the fish and had not caught it.He apologized in public and said that he only did it so his son would be proud of him as a fisherman.So it seems that it was Mr.Thompson who was the big fish!Step Ⅳ Homework

Review the whole unit and prepare for a test.附 件 文化背景知识

Newspaper interviewing tips The best thing to do when interviewing a source is to act naturally.An interview does not have to happen in a formal, suited atmosphere.An interview is just a talk with someone about a specific topic.But instead of merely hearing, the reporter is listening and writing down the pertinent details.Reporters must keep their opinions to themselves.Preparing for the interview Don’t go to an interview unprepared.Check newspaper files and the library for information on your subject or the topic.Have some information in your head before you start.For example, if you are interviewing a person who sells furs and is annoyed by animal rights pickets, it might be interesting to know if this person has a dog or a cat.Have your questions ready.Don’t expect your news source to tell you voluntarily what you want to know.Your questions, although you may stray from them, help you organize your thoughts.They also will remind you to get all the answers you want.Make an appointment.You can’t go into a busy official’s office and get 30 minutes of his or her time unless you first set up an appointment.Then make sure you arrive on time.Dress properly.Be prepared and show respect for the source.Take three things with you on every assignment: a pencil, a piece of paper and a grain of salt.Be a bit skeptical, don’t believe everything you’re told.Conducting the interview Introduce yourself and the publication for which you are writing.Look your subject in the eye.Don’t be so busy taking notes that all the source sees are your flying fingers and the top of your head.It makes some people nervous to see every word being written down.Often, the first question to ask is how to spell the individual’s name.Don’t rely on the spelling you’ve seen somewhere else because it could be wrong.A misspelled name is definitely the first way to lose credibility.Pronounce the name of the respondent correctly and use it from time to time during the interview.Double-check the dates and the spelling of names.Even a name like Smith can be spelled differently.Don’t ever be afraid to ask what you might fear is a silly question.Start with easy, sociable questions to relax the person you’re interviewing.Save the tough questions for later.Avoid questions that appear to have predetermined answers.Don’t let your opinions determine the focus of your questioning.Ask open-ended questions that invite a lengthy answer and can bring out anecdotes and opinions: “How did you react?” or “Why do you think that happened?” Try to take down as many direct quotes as possible.Don’t ask questions that let your source give one-word answers.Don’t ask negative questions.That is, don’t say, “No news, yet?” Don’t make it easy for your subject to say “no”.Let the interviewee know you know something about him or her.This is called priming the interviewee.It goes like this: Mr.Jones, I understand you appeared in a movie about the takeover by people under 30.Do you believe this could actually happen? Accept all facts and other data professionally.Do not argue or show undue shock or surprise.Have a note-taking system.For example, write “rr” for railroad.Do not promise to let the interviewee read the story before it is published.Leave the door open for another talk.Ask the subject if he or she would mind if you made contact later personally or by phone for a follow-up.Get a phone number where the source can be reached later.End the interview by making sure you have a phone number to contact the source later for further facts or clarification.If you use a tape recorder, don’t depend on it.Batteries run down and tape recorders can malfunction.Take notes, even if you’re using a tape recorder.Taking notes Some kind of shorthand is a must.Most reporters use some form of shortened writing, such as “w/o” for without or “inc” for incomplete.Initials can stand for titles and symbols can be used to refer to organizations.Set apart direct quotes with circles, quotation marks, stars or underlining.Taking notes on one side of the paper or pad makes their rearrangement to fit story structure easier.Listen carefully.Don’t note unimportant details.Ask for the spellings on all names and titles.It is better to ask now than to have to call back to get them.Or worse, to get them wrong in the story.Get direct quotations, especially on the main points.Observe details about your source and surroundings, and write down your impressions.Concentrate on what you are seeing and hearing.Immediately after an interview, review and supplement your notes.Arrange your notes in order of importance.It is unnecessary to write complete sentences unless you wish to get a direct quote in its entirety.Write down specific information you cannot trust to memory: ages, names, addresses, statistics, sums of money.Try to get biographical information where needed and look for newspaper clips and other material which may be used for background information.Do not be afraid to double-check unclear information even if you must make a follow-up call to do so.Exciting writing is built on exciting anecdotes, so the interviewer is always listening for them.A really sharp interviewer also listens for clues to experiences that could make lively anecdotes.Then the interviewer directs the subject to “give me an example” or “tell me about a time when that actually happened.” Finding anecdotes An anecdote is a small story.So, anecdotes can become stories within your larger story.Often, an anecdote will illustrate something about the interviewee such as his or her loyalty, bravery, persistence or a quality which a “title story” can illustrate.These must be carefully “mined”.Watch your subject.Observe non-verbal — body gestures, facial expressions, paralanguage(the way

something is said), artifacts(what the person is wearing), movement — of the interviewee.About 70 percent of total communication is non-verbal.Thus, if you are to tell the complete story, you must provide the reader with the complete story.Study the environment Bulletin boards, desktops, pictures on the wall, file cabinets, etc.How does the sunlight stream into the room? And how does all this relate to the interviewee? Avoid using description just for the sake of description.Post-interview Some interviewees are masters at “pulling the wool” over reporters’ eyes.So, be ready to check statements or figures with other sources.You should not take everything at face value.You should be a bit skeptical.Remember: “If your mother says she loves you, check it out!” Newspaper writing tips Writing the story A story is much like a conversation.It begins with the most interesting piece of information or a summary of the highlights and works its way down to the least interesting facts.There are words or phrases that take you from one topic of conversation to another.Before you know it, you’ve finished.Inverted pyramid You should be very familiar with the inverted pyramid style of writing.You’ll

likely use it every day.For example, when you call a friend to tell him or her about a big date, you begin by telling the most interesting and important things first.The least important information is saved for the end of the conversation, and depending on how much time you have to talk, that information may not get into the conversation.That concept also applies to news stories.The lead is the first paragraph of a news story.Usually, the lead is one sentence long and summarizes the facts of the news story in order of most newsworthy to least news-worthy.The reader should know at first glance what the story is about and what its emphasis is.Here is an example: Bargainers from General Motors and UAW Local 160 will resume talks in Warren this morning seeking to end a day-old strike over the transfer of jobs from unionized employees to less costly contract workers.The five Ws and an H Depending on the elements of news value, the summary news lead emphasizes and includes some or all of the five Ws and an H.Who names the subject(s)of the story.The who, a noun, can refer to a person, a group, a building, an institution, a concept — anything about which a story can be written.The who in the lead above are the bargainers from General Motors and the UAW.The what is the action taking place.It is a verb that tells what the who is doing.Reporters should always use active voice and action verbs for the what because they make the wording direct and lively.What are the bargainers doing? The lead says they will resume talks.When tells the time the action is happening.It is an adverb or an adverb phrase.When will the bargainers resume talks? This morning.Where is the place the action is happening? Again, it is an adverb or adverb phrase.In our story, the where is Warren.Why, another adverb, explains the action in the lead.The bargainers are meeting to discuss the transfer of jobs.How usually describes the manner in which action occurs.The lead The lead sets the structure for the rest of the story.If the lead is good, the rest of the story comes together easily.Many reporters spend half their writing time on the lead alone.One guiding principle behind story organization is: The structure of the story can help the reader understand what you are writing about.The structure should lead the reader from idea to idea simply and clearly.The object is to give readers information, and wow them with convoluted style.News lead In one of their bloodiest raids into Lebanon in years, Israeli warplanes killed dozens of Muslim guerrillas with rockets and machine-gun fire Thursday as they pounded a training camp of the pro-Aranian party of God.Quote lead I have the worst job in the Army.This is an example of a good quote lead because the reader asks, “What could that

possibly be?” Description lead Penciled sketches of an air strike, complete with renderings of F14s and Patriot missiles.And on the ground, tiny people run for cover.That’s how 8-year-old Jimmy Zayas pictures war in the Middle East...Like a beauty pageant entrant, Donald Hofeditz struts his vital statistics.He curls his thumb in his waistband to show he’s a size 36, down from 40.He pats his stomach where 50 pounds used to rest.And he rubs his chest about his now healthy cholesterol level of 177.Hofeditz even relishes showing his “before” pictures.The pot-bellied 70-year-old in the early 1980s was unable to cut his backyard grass because of the cumbersome weight.Bad lead A reminder to those who enjoy good new records.The library has 22 new records which it is willing to loan out!The students are invited to come and look them over!In the first place, the opening sentence isn’t even a sentence.There are times when sentence fragments are acceptable if you use them effectively, but that first sentence isn’t one of them.Is it news that the library is willing to “loan out” materials? That’s what libraries are for.The word “out” is unnecessary.And “loan” is an adjective or a noun, not a verb.Make it “lend”.A better way to express the thoughts in this lead would be: Twenty-two new records have been placed in the school’s lending library, the head librarian announced.Transitions With one-sentence paragraphs consisting of only one idea — block paragraphs —

it would be easy for a story to appear as a series of statements without any smooth flow from one idea to the next.Block paragraphing makes the use of effective transitions important.Transitions are words or phrases that link two ideas, making the movement from one to the other clear and easy.Obvious transitional phrases are: thus, therefore, on the other hand, next, then, and so on.Transitions in news stories are generally done by repeating a word or phrase or using a synonym for a key word in the preceding paragraph.Think of block graphs as islands tied together with transition bridges of repeated words or phrases.Direct quotes

You should use direct quotes: If a source’s language is particularly colorful or picturesque.When it is important for written information — especially official information — to come from an obviously authoritative voice to answer the questions “why, how, who or what?” Use a direct quote after a summary statement that needs amplification, verification or example.Remember, a direct quote repeats exactly what the interviewee said.If you don’t have a person’s exact words, you can paraphrase, but you cannot change the meaning of a person’s words.And when you paraphrase, you must never use quotation marks.

A OTTAWA — Canada’s western city of Calgary is the world’s best city when it comes to healthy living, local press reported Monday.According to an international survey by Mercer Human Resource Consulting, a London-based consulting firm, Calgary was put at the top of a list of 144 cities.It scored 121 points, just above Honolulu’s score of 120.Helsinki（赫尔辛基，芬兰首都）and Ottawa followed at 119.5 and 118.5 respectively.Three other Canadian cities came in the top 20.Montreal and Vancouver tied for ninth and Toronto came in at 18th.The scores are based on air pollution levels, availability and quality of hospitals and medical supplies, as well as the efficiency of waste removal and sewage systems.3

In America, the lowest scoring city was Atlanta, which was ranked 76th.Athens was the lowest scoring city in Western Europe, ranking 120th because of its air pollution.London was ranked 59th.1.How many Canadian cities are in the top 20? A.3.B.4.C.5.D.6.2.Which of the following is NOT taken into account when the cities were scored? A.Weather conditions.B.Air quality.C.Waste removal.D.Medical supplies.3.Among the following cities, which is the lowest scoring one? A.Atlanta.B.Athens.C.London.D.Helsinki.B Canada is one of the few nations in the world that have two official languages：English and French.There are 10 provinces in the country but only one of these—Quebec is known as “French Canada”.This is because it was founded by French explorers while British adventurers discovered the rest.Canada left the British empire in 1867 to become an independent country，and English and French have become the official languages ever since.Most people speak English as their first language and the two national television networks broadcast in English throughout the country.Apart from in Quebec and a few places on the east coast，French television is very rare.The same goes for traffic signs and menus，for example，outside of Quebec，there are only a few places where you’ll see traffic signs in French.In restaurants，it’s almost impossible to find French on the menu unless you are in the heartland of French Canada.However，it is claimed by law thay all products sold in Canada must have labels and instructions in both languages.In Canada’s English speaking provinces，official bilingualism(双语)means that students can choose to complete a special French language course.Under this programme，they are taught most of their subjects in French.If a student begins the course in kindergarten or Grade One，it is likely that all their lessons will be in French.However，if they start at junior high school，25 percent of the teaching will continue to be in English.4.How many provinces are there in Canada? A.Ten.B.Nine.C.Eleven.D.Two.5.Which country controlled Canada before its independence? A.France.B.Britain.C.America.D.Germany.6.Where can you watch French television programmes? A.Only in Quebec.B.In Quebec and a few other places.C.From the two national television networks.D.All over Canada.7.What about the education in Canada? A.In English speaking provinces only English courses are offered there.B.If you choose a special French language course，most of the subjects are taught in French.C.The courses in primary school are all taught in English.D.Most of the courses in junior high schools are taught in English.8.Which of the following sentences is right? A.English is the only official language，though French is also spoken there.B.The two national television networks broadcast both in English and French.C.All products sold in Canada must，by law，have labels and instructions in both English and French.D.The lessons in kindergarten or Grade One are likely to be only in English.第2课时reading 5 基础练习

学而思网校 www.xiexiebang.com 相对靠后，在此内容之前学生已经学习了三角函数、平面向量、直线和圆的方程等与本章知识联系密切的内容，这使这部分内容的处理有了比较多的工具，某些内容可以处理得更加简洁。比如对于余弦定理的证明，常用的方法是借助于三角的方法，需要对于三角形进行讨论，方法不够简洁，教科书则用了向量的方法，发挥了向量方法在解决问题中的威力。

在证明了余弦定理及其推论以后，教科书从余弦定理与勾股定理的比较中，提出了一个思考问题“勾股定理指出了直角三角形中三边平方之间的关系，余弦定理则指出了一般三角形中三边平方之间的关系，如何看这两个定理之间的关系？”，并进而指出，“从余弦定理以及余弦函数的性质可知，如果一个三角形两边的平方和等于

标题选择题是主旨大意题的一种，要求给文章选定一个标题，这是高考阅读理解题常考的题型之一。

文章的标题要具有概括性，要能最大程度地覆盖全文，概括文章的主要内容，体现文章的主旨。标题还应具备醒目性，能够吸引读者的注意力，唤起读者对文章的阅读兴趣。

【实例透析】

(2012·安徽高考·B)

[1]Why is pink or purple a color for girls and blue or brown for boys? [2]The answer depends largely on cultural values as well as personal experiences.To the Egyptians，green was a color that represented the hope and joy of spring，while for Muslims，it means heaven.Red is a symbol of good luck in many cultures.In China，children are given money in a red envelope to bring good fortune in the New Year.For many nations，blue is a symbol of protection and religious beliefs.Greek people often wear a blue necklace hoping to protect themselves against evils(灾祸)．

[3]People's choice of colors is also influenced by their bodies' reactions(反应)toward them.Green is said to be the most restful color.It has the ability to reduce pain and relax people both mentally and physically.People who work in green environments have been found to have fewer stomach aches.[4]Red can cause a person's blood pressure to rise and increase people's appetites(食欲)．Many decorators will include different shades of red in the restaurant.Similarly，many commercial websites will have a red“Buy Now”button because red is a color that easily catches a person's eye.[5]Blue is another calming color.Unlike red，blue can cause people to lose appetite.So if you want to eat less，some suggest that eating from blue plates can help.[6]The next time you are deciding on what to wear or what color to decorate your room，think about the color carefully.63．Which of the following would be the most proper title for the text? A．Colors and Human Beings B．The Cultural Meaning of Color C．Colors and Personal Experiences D．The Meaning and Function of Color 【解析】 D。主旨大意题。全文以green，red，blue等颜色为例阐述了不同颜色的文化意义和作用。A“颜色与人类”，题目过于宽泛；B“颜色的文化意义”没有涵盖颜色的作用，文章从第三段起就主要说明颜色的作用；C“颜色和个人经历”在第二段的首句提到，但是不能涵盖全文的内容。文章第一段以问句开始，以引起读者的兴趣，接着从颜色的文化意义和颜色的作用两个方面展开说明，故答案为D项。

【技巧点拨】

解题时关键要抓住文章的首尾段和每一段的首尾句，要注意贯穿文章始终的词语。不同体裁的文章的主题位置不同，比如从新闻报道的第一段就可以知道主题是什么。议论文多是“总—分—总”的结构，所以首尾段是关键；说明文的解题关键在主题句；记叙文要注意六个要素，即5个W(what，who，where，when，why)和一个H(how)。同时还要注意标题有时用的是省略形式，比如用分词作定语代替定语从句等。

【现场练兵】

The 2012 London Olympics had enough problems to worry about.But one more has just been added — a communications blackout caused by solar storms.After a period of calm within the Sun, scientists have detected the signs of a fresh cycle of sunspots that could peak in 2012, just in time for the arrival of the Olympic torch in London.Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth, causing strong solar storms that could jam the telecommunications satellites and Internet links sending live Olympic broadcast from London.“The Sun's activity has a strong influence on the Earth.The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites，” said Professor Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxfordshire....75.Which of the following might be the BEST title of the passage? A.Solar Storms: An Invisible Killer B.Solar Storms: Earth Environment in Danger C.Solar Storms: Threatening the Human Race D.Solar Storms: Human Activities to Be Troubled 【解析】 D。标题选择题。根据第一段可知本文的话题是Solar Storms，那么该话题的控制性概念是什么呢？A项是“无形的杀手”；B项是“地球环境处于危险中”；C项是“威胁着人类”；D项是“人类活动受到干扰”。文章的主要内容是太阳风暴会影响2012年奥运的通讯系统和网络连接，这应该属于“人类活动”概念，故D项是最佳标题。

【能力测试】

阅读理解。阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。

A MENTORING(导师制)program is giving life changing opportunities to Banbury youth.Young Inspirations was founded two years ago to provide mentoring sessions for students and unemployed young adults aged 11 to 21.Alex Goldberg，the program's founder，said：“We set up Young Inspirations because we wanted to give young people experiences which will potentially be life changing and broaden their outlook.”

“We try to create work experience opportunities that will really make a difference to our youth.For example，we've secured internships(实习)with world­famous firms such as Honda.”

“At a time of funding cutbacks where schools are finding it more and more difficult to offer this kind of mentoring，it is extremely important that these opportunities are available both to help youth with their school work and grades and to give them opportunities which may help shape their futures.” Kieran Hepburn,14，is one of a group of Banbury youth who has benefited from the program so far.In October the Banbury School pupil was accompanied by Young Inspirations staff to Paris where he was an observer at the United Nations Educational，Scientific and Cultural Organization's(UNESCO)International Youth Forum(论坛)．

The event was held for young people from around the world，to seek their views on how the future of youth and education should look.Kieran joined several hundred observers mostly in their 20s and was the only UK school pupil to attend the event.Kieran thinks the trip was a life changing experience.“Before we left I didn't quite know what to make of it but when we got there we didn't stop，it was amazing，” he said，“We went to three or four hours of debates each day and then did something cultural each afternoon.”

The main theme of the forum was how youth can drive change in political and public life.It dealt with issues(问题)such as drug abuse，violence and unemployment.Kieran said：“It has really helped me to improve my confidence and social skills as well as my school grades and I was voted most improved pupil at school in August.”

The Young Inspirations mentoring sessions take place each Friday in Banbury.For details visit www.xiexiebang.com.1．The Young Inspirations mentoring program aims to ______.A．train staff for world­famous firms B．offer job opportunities to young adults C．provide youth with unique experiences D．equip the unemployed with different skills 解析 细节理解题。由第三段中的“‘We set up Young Inspirations because we wanted to give young people experiences...'”可知目的是给青年提供独特的经历。答案 C 2．According to Alex Goldberg，it is difficult for schools to offer the mentoring due to ________.A．the lack of support from firms B．the cultural differences C．the effect of unemployment D．the shortage of money 解析 推理判断题。由第五段中的“funding cutbacks”(削减资金)可知，缺乏资金给导师制的发展带来了困难。答案 D 3．We can learn from the passage that ________.A．the visit to the United Kingdom was amazing B．Kieran has made great progress in many aspects C．the youth have found a way to solve their problems D．the mentoring sessions are held every day except Friday 解析 推理判断题。由文章倒数第二段中的“‘It has really helped me to improve my confidence and social skills as well as my school grades and I was voted most improved pupil at school in August.'”可知Kieran在很多方面取得了进步。故选B项。答案 B 4．What would be the best title for the passage? A．Alex Goldberg，Founder of Young Inspirations B．Young People Find a World of Opportunity C．Kieran，Banbury School Pupil to Paris D．Debates Help Youth with Their Grades 解析 标题归纳题。本文主要就Alex Goldberg创建了导师制，给青年人提供了了解社会、获得社会经验的机会，最后这个项目扩大到国际范围，给青年人改变自己和社会的机会。所以正确答案为B。答案 B

第五篇：2014年高中数学 1.1.1正弦定理教学设计 新人教A版必修5

第一章 解三角形

1.1.1正弦定理

教材分析与导入

三维目标

一、知识与技能

1.通过对任意三角形边长和角度关系的探索，掌握正弦定理的内容及其证明方法；

2.会运用正弦定理与三角形内角和定理解斜三角形的两类基本问题．

二、过程与方法

1.让学生从已有的几何知识出发,共同探究在任意三角形中，边与其对角的关系；

2.引导学生通过观察、推导、比较，由特殊到一般归纳出正弦定理；

3.进行定理基本应用的实践操作．

三、情感态度与价值观

1.培养学生在方程思想指导下处理解三角形问题的运算能力；

2.培养学生探索数学规律的思维能力，通过三角函数、正弦定理、向量的数量积等知识间的联系来体现事物之间的普遍联系与辩证统一．

教学重点 发现正弦定理、用几何法和向量法证明正弦定理。正弦定理是三角形边角关系中最常见、最重要的两个定理之一，它准确反映了三角形中各边与它所对角的正弦的关系，对于它的形式、内容、证明方法和应用必须引起足够的重视。正弦定理要求学生综合运用正弦定理和内角和定理等众多基础知识解决几何问题和实际应用问题，这些知识的掌握，有助于培养分析问题和解决问题能力，所以一向为数学教育所重视。

教学难点

用向量法证明正弦定理。虽然学生刚学过必修4中的平面向量的知识，但是要利用向量推导正弦定理，有一定的困难。突破此难点的关键是引导学生通过向量的数量积把三角形的边长和内角的三角函数联系起来。用平面向量的数量积方法证明这个定理，使学生巩固向量知识，突出了向量的工具性，是向量知识应用的范例。教学建议

正弦定理是刻画三角形边和角关系的基本定理，也是最基本的数量关系之一。此节内容从地位上讲起到承上启下的作用：承上，可以说正弦定理是初中锐角三角函数（直角三角形内问题）的拓广与延续，是对初中相关边角关系的定性知识的定量解释，即对“在任意三角形中有大边对大角，小边对小角”这一定性知识的定量解释，即正弦定理得到这个边、角的关系准确的量化的表示，实现了边角的互化。它是三角函数一般知识和平面向量知识在三角形中的具体应用，同时教材这样编写也体现了新课标中“体现相关内容的联系，帮助学生全面地理解和认识数学”这一指导思想；启下，正弦定理解决问题具有一定的局限性，产生了余弦定理，二者一起成为解决任意三角形问题重要定理。同时正弦定理为后续第二节的《应用举例》作以铺垫，正弦定理的知识和方法可解决一些与测量和几何计算有关的实际问题，这样也体现了课标中注重“数学的三大价值（科学价值、应用价值、文化价值）之一的应用价值。”

本节课宜采用“发现学习”的模式，即由“结合实例提出问题——观察特例提出猜想——数学实验深入探究——证明猜想得出定理——运用定理解决问题”五个环节组成的“发现学习”模式，在教学中贯彻“启发性”原则，通过提问不断启发学生，引导学生自主探索与思考；并贯彻“以学定教”原则，即根据教学中的实际情况及时地调整教学方案。导入一

师如右图，固定△ABC的边CB及∠B，使边AC绕着顶点C

转动．

师思考：∠C的大小与它的对边AB的长度之间有怎样的数量关系？

生显然，边AB的长度随着其对角∠C的大小的增大而增大．

师能否用一个等式把这种关系精确地表示出来？

师在初中，我们已学过如何解直角三角形，下面就首先来探讨直角三角形

中，角与边的等式关系．如右图，在Rt△ABC中，设BC =A,AC =B,AB =C,ab

根据锐角三角函数中正弦函数的定义，有c=sinA，c =sinB，又cabccc,则sinAsinBsimC.从而在直角三角形ABC中，sinC=1=

abcsinAsinBsimC.导入二

师：关于三角形中的边与角的关系我们知道哪些？

sinA生：直角三角形的勾股定理.，还有absinBc，c。

生：有。大边对大角，小边对小角。

师：两位同学回答了一个特殊三角形——直角三角形中的边角关系。对于一般三角形的边角关系我们有结论吗？

师：对这一结论同学们能提供一些想法吗？

生：有点像正比例关系。

师：在△ABC中A与a，B与b，C与c，他们有怎样的正比例关系？

(1)akA，bkB，ckC；(2)aksinA，bksinB，cksinC；

(3)akcosA，bkcosB，ckcosC；(4)aktanA，bktanB，cktanC。请同学们验证这些猜想的正确性，然后选出正确的。

正确答案为(2)

从而得到：在一个三角形中，各边和它所对角的正弦的比值相等，abc

即sinAsinBsinC.这就是我们今天要研究的——正弦定理
