Unit 2 RobotsPart 1 Teaching Design第一局部教学设计Period 2 A sample lesson plan for Learning about Language(Revise the passive voice including the infinitive)IntroductionIn this period students will be first helped by the teacher to discover and learn to use some useful words and collocations, and then to discover and revise the passive voice including the infinitive. The following steps of teaching may be taken: warming up by having a dictation, discovering useful words and collocations, reading more about the 22nd century, learning about the passive voice, discovering useful structures and closing down by putting on stage a text play of Satisfaction Guaranteed. ObjectivesTo help students revise the passive voiceTo help students discover and learn to use some useful words and collocationsTo help students discover and learn to use some useful structuresProcedures1. Warming up by having a dictationTo begin with, let’s take a dictation to strengthen our memory of the text.Larry Belmont worked for a pany that make robot. Recently a robot that could do housework would be tested out Larry's life, Clair, for three weeks. Clair felt alarmed by the robot's humanly appearance. Before long she began to trust him. She told him that she and her home were not elegant enough for her husband and she envied the rich and powerful woman .The robot decided to protect her from being harm. He gave her a new haircut and changed her makeup and asked her to buy something to decorate her home. Before the night he was to leave Clair, they held a party. The guests were impressed by Clair and her home, especially by the handsome robot, whom they thought was her husband. Claire knew this is almost a dream and she felt very sad. However, the pany was very satisfied with Tony, the robot although he needed rebuilding because it is absurd to have women falling in love with a machine.2. Discovering useful words and collocationsA collocation is two or more words that often go together. These binations just sound "right" to native English speakers, who use them all the time.While going over the text, try to recognize the collocations, treat them as single blocks of language and copy them out into your Collocation Book.Now go to page 13. Work in pairs to finish the three exercises in 10 minutes.3.

被动语态及其时态
一、语态分类
英语动词有两种语态：主动语态和被动语态。主动语态表示 主语是动作的执行者，被动语态表示主语是动作的承受者。 They will build a new bridge over the river. (主动) A new bridge will be built over the river. (被动) 汉语中常用“被”“给”“由”“受”等词肉已炖了好长时间了。 (被动句) 2．感官动词一般用主动形式表示被动意义。常见的动词 有 ： go ， appear ， touch ， feel ， look ， seem ， taste ， sound，grow/become/get，remain等。
The cup was broken by Paul.
语 法 精 讲
四、主动形式表示被动意义的几种情况
1．某些动词与well，badly，easily 等副词连用时突出主
语内在的品质特征或是性能，这时这些动词是不及物动 词，用主动形式表达被动含义。常见的动词有：write， sell，read，clean，wash，cook等。 The cloth washes easily. The new product sells well. The pen writes smoothly. 对比以下句子：
语 法 精 讲 9．含有情态动词的被动语态。 含有情态动词的被动语态由“情态动词＋be＋及物 动词的过去分词”构成。 You must hand in your compositions after class. →Your compositions must_be_handed_in after class.

2. 在使役动词have, make, get以及感官 动词see, watch, notice, hear, feel, observe等后面不定式作宾语补语时， 在主动结构中不定式to要省略，但变为 被动结构时，要加 to。

When doing Ex1 and Ex3 on Page 13, students may use an English-English dictionary so that they can understand the situations where the words are used.Ex1 will help students to form the habit of thinking in English.Ex2 will help students to master the useful words and phrases in context.Ex3 will help students to learn more about word formation and use the words in proper situations. After dealing with Ex3, point out words like alarmed are adjectives, when following the link verb be, it is used to describe a feeling. Sentences that have such structures are not passive.T: Look at the following sentence: My mother felt alarmed when I had my hair coloured purple. If I use was to replace felt, the sentence will be: My mother was alarmed when I had my hair coloured purple. Is this a passive sentence?Ss: No. Though the structure seems like a passive sentence, it is not. A passive sentence indicates a passive action while this sentence describes a situation when someone has the feeling of alarm. “Alarmed” is an adjective formed by v+ed.T: Quite good. Please remember not all be + v +-ed /-en / -t sentences are passive.Step ⅢGrammar studyGo over the passive voice: be + v +-ed / -en / -tT: Please give some examples of passive sentences.S1: My homework was eaten by the dog.S2: The toy is made by hand....T: Good. Please remember the passive is formed with any time frame of the verb.Show the following on the PowerPoint.to be + past participlee.g. The Mona Lisa was painted by Leonardo da Vinci.Research is now being done on a cure for this disease.The game of Monopoly can be played by two to four players.Reports on several new gun laws were being discussed.My stereo has been stolen by a thief.Go over the infinitiveT: In Unit 1 we’ve learned the infinitive. Please recall the functions of the infinitive.Ss: Except predicate, the infinitive can function as subject, object, predicative, attribute, adverbial and object compliment.T: Today we are going to learn more about the infinitive—the passive infinitive.Explanation of the passive infinitiveto be + past participleeg. to be given, to be shut, to be openedWhen the grammatical subject of the sentence receives the action, we use the passive infinitive. For example:She hates to be laughed at. (others laugh at her→ she is laughed at by others)I am expecting to be given a pay rise next month. (give me a pay rise→ I will be given a pay rise.) be to + passive infinitive (to be + past participle) is often used in notices and instructions. Examples:This cover is not to be removed.The medicine is to be taken three times a day.To be taken three times a day after meals.These benches are not to be removed from the changing rooms.No food of any kind is to be taken into the examination room.Deal with Exx 1-4 on Page 14. Ask students to do the exercises one by one. Then continue with the exercises on the workbook. While dealing with Ex2 on Page 56, point out to students that “need to be done” has the same meaning as “need doing”. Before translating the sentences in Ex3, students should decide the key words and main structures first. After students have finished, show some students’ work on the projector or bulletin board on the computer, check their work w ith the whole class. Correct the errors if there are any.Ask students to write down the sentences in Ex3 in their exercise books after class.Step ⅣHomeworkGo over the key words and expressions.Go over the grammar.Do Ex3 on Page 56.。
