二、学习分析苏霍姆林斯基认为:“教给学生方法比教给学生知识更重要。
”建构主义是近年来介绍到我国的一种新兴教育理论,它认为知识不是通过教师传授得到,而是学习者在一定的情境即社会文化背景下,借助学习过程中其他人(包括教师和学习伙伴)的帮助,利用必要的学习资料,通过意义建构的方式获得的。
基于这样的认识,结合本课内容和初三年级学生的特点及学习经历,在教学中我侧重指导学生采用以下三种学习方法:1.合作学习法。

Status and function: This is the first part of Section B, it links the preceding with the following in Unit 9. Not only does it help the students review the food words and the Passive Voice they have learnt before, but also it helps them learn to describe different tastes and talk about the history of the invention. Such a topic is related to daily life, so it is helpful to inspire the students‟ learning motivation and interest.2. Teaching aims and demandsKnowledge aims:☆ The target words: crispy, salty, sour, chef, sprinkle, by mistake.☆ The target language: Did you know potato chips were invented by mistake?Wow, I didn‟t know that. Who invented them? ...etc.Ability aims:☆Be able to describe different tastes using the target words.☆Train the students‟ listening, speaking, reading and writing skills with the target language. Moral aims:Cultivate the students‟ ability of observation, imagination and their spirit of innovation.3. Teaching emphasis and difficulties:Important pointsThe target words and language.(According to the English syllabus and the language structures in this lesson.)Difficult points:The listening practice and correctly express the history of the invention.(According to the teaching prediction and the students‟ cognitive level)Part 2 Analysis of teaching methods1. Teaching methods:“Task-based teaching method “with the help of useful situations to classify the tasks and give different students different evaluations.(To make language learning successful through a step-by-step progression that builds confidence and leads to open-ended activities.)2.Teaching aids:Multimedia computer, Tape recorder, PowerPoint.(According to the students‟ psychological characteristics. They enjoy music, pictures and cartoons.)Part 3 Teaching proceduresStep 1 BrainstormingPlay guessing games: what inventions are they?One student comes to the front to guess, the others describe an invention shown on the screen using the passive sentences: It‟s used for… It was invented by…It was invented in…etc.Take turns to show …light bulb, alarm clock, microwave oven‟with some other helpful pictures that center about them nearby on the screen.(Purpose of designing: To guide the students to review what they learned last lesson)Step 2 Leading-inT: The microwave oven reminds me of some delicious food. I will play a cartoon called “music food” My favorite food is in it. Try to guess what it is.Every time when they give a guess, I will express my like and dislike by using some adjectives like sweet, crispy, salty, sour . Make sure they know the meanings of them. For example:S:ChocolateT: It‟s very crispy, but it‟s too sweet. I don‟t like it Can you guess the meaning of …crispy‟? It describes food that is hard .dry and easily broken.S :Milk.T:I prefer sour milk to milk. Do you know …sour‟? Oranges somet imes taste sour.S: Fish.T: yes! Fish is my favorite, and I especially like salty fish that is sprinkled with a lot of salt.During this course, write down the new words on the blackboard..Finally play a leading role to read them.(Purpose :To arouse the students‟ interest ,create useful situations for them to learn the new words. Prepare for the next step. )Step 3 PracticeTask One writing1a.Show four food pictures on the screen and get the students to describe how the food tastes and write them down.1b.Ask them to list the words of the food that has different tastes according to the headings on the screen as many as possible .sweet crispy salty sourThe teacher moves around the classroom to provide help for the students who have trouble in spelling some hard words and choose three students who write different words from one another.(Purpose: To practice using the target words and review the food words they have learnt before.)Task Two Speaking and actingGet the three students to the front, divide the class into four groups:Sweet Group , Crispy Group, Salty Group , Sour GroupGame begins: The three students read their words loudly in class one by one without repetition, the group members should stand up as soon as they hear a word that belongs to them. Call out the students who stood up by mistake and have them guess the meaning of …by mistake‟.(Purpose: This is employed to show the words they wrote and link the target words with the food words, and get the whole class moving.)Step 4 PresentationT: Just now you mentioned many kinds of food, but do you know there are some interesting stories behind them. Here is one.Ask the students to look at the picture in 2a and imagine what they are talking about.S: They are talking about the story of potato chips.T: Right .Maybe on the bag it says the invention of them!(Purpose: Cultivate their ability of imagination and present the invention of potato chips.)Step5 PracticeTask One Listening and understanding2a. Let the students look through the six sentences in the box and get some information from them. Then play the tape recording twice for them to listen and circle T or F. Check the answers.(Purpose: To provide practice in listening and understanding the target language in spoken conversation.)Task Two Listening and writing2b. Before playing the recording, get the students to try to give answers by memory, or just by guessing. After a while, play the recording for them to fill in the missing words they hear. Then check the an swers while concentrating on the new words: chef, sprinkle…on…(Purpose: To provide practice in understanding and writing the target language ,break through the difficult point.)Task Three Pairwork2c.Ask the students to make conversations using the information in 2a and 2b ,then ask some pairs to act them out. as follows:A: Did you know potato chips were invented by mistake?B: Wow, I didn‟t know that. Who invented them?A: They were invented by a chef called George Crum.B: …(Purpose: Students are willing to show themselves and this task provides benefits for both more fluent and less fluent students to use the new language to talk with others and achieve the ability aim.)Task Four GroupworkT: Are you interested in the history of the sandwich?Show some pictures about the story of sandwiches on the screen, get them to discuss the history in groups of four as follows:Then each group choose a leader to give a report in class after that .(Purpose: This is employed to do further consolidation and extension using the target language, it also fosters a sense of cooperation in the classroom.)Step 6 HomeworkT: Think of a kind of food you like best and try an unusual way to cook at home and write your experience in your exercise book. And ask your parent to sign his/her name on your book.(Purpose: The new type of homework is employed to relate the knowledge that they learn from this lesson with the life realities, and achieve the moral aims.)Blackboard design:(Purpose: To show the language structures they mainly learn from this lesson.)Part 4 Teaching reflectionAccording to << English Course Standard >>,I combine different language structures and functions with different studying tasks. I put emphasis on raising the students‟ interest, forming effective strategies and developing the cooperative spirit. And I think I‟ll make it.This is a period of various contents, maybe the time of one class is not enough, I need to adjust the teaching steps according to the actual situations. And in 1b. of Step3,it requires the teacher to have a large vocabulary to provide help for students. One minute in class, ten years‟ hard working after class—I need to hold on to studying to improve myself.。

Unit 9 By the time I got outside, the bus had already left一.学习目标(Language Goal)1.Learn to narrate past events.学会描述过去所发生的事情。
2.Learn to express something with Past Perfect Tense. 学习使用过去完成时态。
3.Strengthen the consciousness of doing things regularly.做事加强连续性,有条不紊。
二.语言结构(Language Structures)1.Past perfect Tense 过去完成时2.“By the time”和“when”引导的时间状语从句三.目标语言(Target language)1.By the time she got up, her brother had already gone into the bathroom.2.By the time she went outside, the bus had already gone3.By the time she got to class, the teacher had already started teaching.4.When she got to school, she realized she had left her backpack at home5.Have you ever overslept?6.Have you ever been late for school?四.重点词组(Key phrases)1.by the time 到…时候为止2.get outside 到外边3.get to school 到学校4.get up 起床5.get into the shower 去洗澡6.get home 到家7.start doing / to do sth 开始做某事8.be late for 迟到9.go off (闹钟)闹响10.wake up 醒来11.come out 出来,出现12.run off 迅速离开,跑掉13.on time 准时14.in time 及时15.come by (走)过来16.give sb a ride 让某人搭车17.break down 损坏,坏掉18.show up 出席,露面19.stay up 熬夜20.a costume party 一个化装舞会21.sth happen to sb 某事发生在某人身上22.so …that … 如此…以至于23.set off 出发,开始24.April Fool's Day 愚人节25.get married 结婚26.marry sb 与某人结婚27.both …and … 二者…都…28.get dressed 穿好衣服29.on the first day 在第一天五.语法重点(Grammar Focus)1.Past perfect Tense 过去完成时构成:had+过去分词(had没有人称和数的变化)过去完成时可以表示过去某一时刻或某一动作之前完成的动作或呈现的状态。
也就是说发生在“过去的过去”。
既然过去完成时的动作发生在过去某一时间之前,那么,使用过去完成时就必须先有这样一个过去的时间。
eg.I had finished my homework before supper.我在晚饭前把作业做完了。
句中的supper既是过去某一时间,而had finished 这一动作就是在supper 之前完成的。
如果只说I had finished my homework.听者会觉得难以理解。
由此可见,过去完成时是个相对的时态,它不能离开过去的时间而独立存在。
eg.By the end of that year Henry had collected more than one thousand foreign stamps.到那年年底,亨利已经收集了一千多张外国邮票。
(过去时间是the end of that year)eg.When we got there, the football match had already started.当我们到那里时,足球比赛已经开始了。
(过去时间是when从句)动词过去分词的构成与一般过去式的构成相似,一般情况下在动词词尾加-ed,特殊动词须特殊记忆,如:have—had—had,get—got—gotten,begin—began—begun,leave—left—left,go—went—gone等。
例如:She had learnt 2000 English words by the end of last month.到上个月末,她已经学了2000个英语单词了。
I hadn't learnt Japanese before I went to Japan.我去日本之前没学过日语。
注意:过去完成时的否定句和疑问句直接通过had的变化即可。
2.when 和by the time引导的时间状语从句by the time 到……时候为止,指从过去某一点到,从句所示的时间为止,这一时间段。
when当……时候,指过去的某一时间点。
从句用一般现在时,主句为过去完成时。
eg.By the time she got up, her brother had already gone into the bathroom.到她起床的时候,她的弟弟已经去洗澡间了。
By the time she went outside, the bus had already gone到她走到外面的时候,公共汽车已经走了。
When she got to school, she realized she had left her backpack at home当她到学校的时候,她意识到她把书包放在家里了。
(在这句话中,过去的时间点为“到校”的时候,“她把书包放在家里”则发生在“过去的过去”。
)3.How to narrate past events.如何描述过去的事件描述过去的事件,首要注意一点是时态。
由于事情发生在过去,因此一定要用过去的某种时态。
但如果是直接引语(如在双引号“”之内),则根据当时的情况来决定。
表示过去的时态有:(1)一般过去时:结构:动词的过去式(2)过去进行时:结构:was / were +现在分词(3)过去完成时:结构:had+过去分词(4)过去将来时:结构:would+动词原形请看例文1:It was Sunday.I went to a pool to fish.I thought there must be some fish for me to catch.I held my fishing pole, waiting patiently.Suddently a big fish was caught.I was glad and put it into my little basket.Before long my sister cameWithout a word she put back the fish into the water.I was astonished.I really thought she became mad.She ordered me to put down the fishing pole and led me to a place not far away.There stood a sign, reading”No fishing”.I realized that I was making a mistake(注意观察文中时态的应用)例2:请大声朗读Section A 3a,并找出其中用到的时态。
六.疑难解析(Key Points)1.get to 意为“到达”。
例如:When did you get there last night?你昨晚什么时候到那儿的?I get home at 7:00 every day.我每天7:00到家。
When I got to the cinema, the film had already begun.我到电影院时,电影已经开始了。
辨析:get, arrive与reach这三个词都可以用来表示“到达”,但是用法不同。
(1)get和arrive都是不及物动词,其后只能跟表示地点的副词,若是跟名词则须再加介词,即get to +地点名词,arrive in / at +地点名词(in 之后跟表示大地方的词,at之后跟表示小地方的词)。
若是只说“到达”,而不指出到达哪里,则只能用arrive。
例如:How did you get / arrive there?你怎么到那儿的?I got to / arrived in Beijing the day before yesterday.我前天到的北京。
When do you often get to / arrive at school?你经常什么时候到校?When will you arrive?你什么时候到?(2)reach为及物动词,其后既可跟名词也可跟副词。
例如:I reached Beijing the day before yesterday.我前天到的北京。
We reached here on foot.我们步行到这儿的。
2.关于get的词组小结在本单元出现大量关于get的词组,要注意背诵:get to school 到学校get into the shower 去洗澡get outside 到外边get home 到家get up 起床get married 结婚get dressed 穿好衣服get to class 到班级get bored 变得无聊get tired 变得疲劳3.I've never been late for school, but yesterday I came very close我上学从未迟到过,但是昨天差一点儿就迟到了。
(1)I've 是I have的缩写,have been late是现在完成时态,现在完成时是指一个动作或状态开始于过去,持续到现在,并可能继续下去,而且对现在产生了一定的影响,其构成是have / has+动词过去分词。
例如:I have been here since 1999.自1999年以来我就在这儿。
