2019-2020年高一英語(yǔ)上冊(cè) nit11 The sounds of the world(第五課時(shí))教案 大綱人教版第一冊(cè) Teaching Aims: 1. Summarize the Passive verb-forms in different tenses. 2. Revise the use of the Passive Voice in different tenses. Teaching Important Point: The form and use of the Passive Voice. Teaching Difficult Point: How to change the Active Voice into the Passive Voice. Teaching Methods: 1. Revision to help the Ss to remember what they have learned. 2. Practice to help the Ss to master the important points. Teaching Aids: 1. a projector and some slides 2. the blackboard Teaching Procedures: FStep Ⅰ. Greetings Greet the whole class as usual. FStep Ⅱ.Revision T: In this class, we’ll revise the Passive Voice we have learned. We know the basic form of the Passive Voice is“be+ past participle”(Bb: be +p.p.).As we know, the Passive Voice is generally used when the doer is not important or unknown, or when we wish to highlight the object of an active sentence. The agent introduced by“by”is the same person or thing as the subject of an active sentence. Please look at the examples on the blackboard and pare them. (Bb: Mr Smith locks the gate at 6 o’clock every night. The gate is locked by Mr Smith at 6 o’clock every night.) The agent is only expressed when it is important to say who or what something is done by. In most passive sentences, there is no agent. As for the tenses of the passive verbs and the rules for their use, they are the same as for active verbs. Now let’s do the exercise on the screen to revise the Passive verb-forms and their use in different tenses. Then we’ll fill in a form. (Teacher shows the exercise on the screen. First ask Ss to finish it individually and check the answers with their partners. Then show the right answers on the screen.) Rewrite the sentences in the Passive Voice. 1. People regard him as a brave man. 2. He published the book in 1960. 3. The man is repairing his car at the moment. 4. He said they were building the bridge. 5. Her friends will give her many presents at her birthday party. 6. He said that a special mittee would examine the plan. 7. I cleaned my shoes this morning. 8. Two men tried to sell the painting that they had stolen. Suggested answers: 1. He is regarded as a brave man. 2. The book was published in 1960. 3. The car is being repaired at the moment. 4. He said the bridge was being built. 5. She will be given many presents at her birthday party. 6. He said that the plan would be examined by a special mittee. 7. My shoes were cleaned this morning. 8. Two men tried to sell the painting that had been stolen. T: Now look at the answers on the screen and sum up the passive verb-forms in different tenses. Fill in the form on the blackboard with the verb “do” as an example. FStep Ⅲ.Discussion T: Let’s discuss the following sentences on the screen.Put them in the Passive Voice. (Show the sentences on the screen.) 1. My brother gave me two notebooks this morning. 2. We elected him monitor of our class. 3. How did you make it clear? 4. He made the boy stand still. 5. We have sent for the doctor. 6. We shall make use of every minute and second. T: (A few minutes later.)Are you ready? Who will give the answers? SA: I was given two notebooks this morning. SB: Two notebooks were given to me this morning. SC: He was elected monitor of our class. SD: How was it made clear? SE: The boy was made to stand still. SF: The doctor has been sent for. SG: Every minute and second will be made use of. (After Ss finish them, teacher shows all the right answers on the screen and gives some explanations.) T: You all did very well.(Pointing to the first and the second sentences)If there are two objects in a sentence, either can be used as subject. Most often in such cases the person bees the subject of the passive verb. (Pointing to the third and the fourth sentences)If the predicate is a verb with plex object, we use the object as the subject in the Passive Voice, object plement is left as the subject plement. In the fifth sentence, when “make” is used as the predicate, we use “stand” not “to stand”as object plement. But in the Passive Voice, we should use “to stand” not “stand”.Can you give other verbs like “make”? Ss: Look at; see; watch; observe; notice; listen to; hear; have; let; feel etc. T: In the last two sentences, the predicate is phrasal verbs. We should remember that when they are changed into the Passive Voice, the prepositions should not be lost. Have you any questions? Well, there are two points we should remember. 1. Some transitive verbs denoting state can not be used in the passive voice. e.g. The book cost me three dollars. I have a book. 2.The examples of some active forms in passive sense. e.g. The door won’t shut. The knife cuts well. The dish smells nice. Much remains to do. The radio needs repairing. Other verbs; read; draw; write; clean; cook; add up; look; sound; feel; taste; want; require etc. should be remembered, for they are the same as those in usage.
