2019-2020年高中英语（人教大纲）第二册上：Unit8 First aid(第五课时)Teaching Aims.1. Review the learnt sentence structure in the Subjunctive Mood.2.

Inductive method to learn the Subjunctive Mood in different cases.2. Practise to learn to use the Subjunctive Mood.Teaching Aids:1. a projector2. the blackboardTeaching Procedures:Step I GreetingsGreet the whole class as usual.Step RevisionT: In Unit 7 and Unit 8, weve learnt some sentence structures to talk about events or situations which are not certain to happen. This is called the Subjunctive Mood. We use a special group of verb-forms to express it. Now lets do an exercise. Look at the screen. Fill in the blanks using the right form of the verb in each bracket.(Teacher shows the following on the screen.)1. I didnt see your sister at the meeting. If she (e), she would have met my brother.2. I wish (be) as strong as you.3. If I (know) German, I would read the book in the original.4. Ive loved you as if you (be) my son.5. If I (do) it, I would do it in a different way (Teacher gives the students some time to prepare, and then check the answers with the whole class.)Suggested answers:1. had e 2. were 3. knew 4. were 5. were to doT: Well done. Today were going to learn more about the Subjunctive Mood. Look at the screen.Step Summary of the Subjunctive Mood Teacher shows the following on the screen.1. If I were you, I wouldnt lose heart. If I knew her name this time, I would tell you.2. If I had left a little earlier, I would have caught the train.3. If they were to/should act like that again, we should criticize them severely. If I got rich, Id travel round the world.T: Please look at the first pair of sentences. They both talk about unreal or improbable present situations. The past tense is used in the if-clause; would + an infinitive in the main clauset were is usually used instead of “was” .Can you understand?Ss: Yes.T: Then what about the second sentence? Han Mei, you try, please.S1: The second sentence talks about things that did not happen in the past. The past perfect is used in the if clause; would + the present perfect in the main clause.T: Quite right. Zhang Hai, you try the third pair of sentences.S2: This pair of sentences talks about improbable future. were to or should + an infinitive or the past tense is used in the if-clause would+ an infinitive in the main clause.T: Very good. In addition, should, might, could are also possible in the main clause of each ease. (Teacher writes the verb-form in each case on the Bb.)T: And the structure were I/you/he/ etc. should I/you/he/etc and hadI/you/he etc can be used instead o if I/you/he/etc. were if I/you/he/etc. should and if I/you/he/etc. had. Can you understand? (Teacher writes them on the Bb.)Ss: Yes.T: Now, please rewrite these sentences on the screen if possible. Volunteers?S3: Were I you, I would not lose heart.S4: Had I left a little earlier, I would have caught the train.S5: Should they act like that again, we should criticise them severely.T: Well done. But theres another case you should pay attention to. Sometimes, the if-clause and the main clause dont talk about events or situations happening at the same time. In this ease, the verb-form depends on its own meaning. Look at the examples on the screen1. If the weather had had been more favourable, the crops could be growing still better.2. If we hadnt been working hard in the past few years, things wouldnt be going so smoothly.3. Amy would be alive today if the doctor had e sooner last night.(Teacher and the students go through the sentences on the screen and study them together.)T: Next, lets learn the verb-forms after wish. Look at the sentences on the screen.1. I wish I were handsome. ( I am not handsome) I wish you didnt work so hard. (You work too much.)2. She wishes she hadnt said it. (She said sth. unpleasant.)3. I wish you would shut up. (You will talk all the time.)T: In the first pair of sentences, the past tense is used after wish to express a present meaning; in the second sentence, a past perfect tense is used to express a past meaning; in the third sentence, would + an infinitive is used to express a future meaning. Is that so?Ss: Yes.T: And the verb-forms after as if or as though is the same as the verb-forms after wish. Look at the examples on the screen.1. Ive loved you as if you were my daughter.2. They talked as if they had been friends for years.3. It seems as if it would rain.(Teacher and the students go through the examples together to make sure the students understand them. Then teacher goes on with some other cases.)T: Well, lets look at some other cases in which the Subjunctive Mood is used. Look at the screen again.1. after the verbs order, mand, insist, demand, desire, request, remend, propose, suggest and other verbs with similar meaning followed by that-clausee. g. We insist (that) a meeting (should) be held as soon as possibleI suggest (that) we (should) set off straight way. They demanded that the aggressor troops (should) be withdrawn immediately. 2. in the Predicative Clause or the Appositive Clause after the nouns suggestion, order, proposal, advice, demand, request, requirement, etc.e. g. My suggestion is that we (should) send a few people to help the other groups. He made a suggestion that they (should) carry on their conversation in French.3. in the construction “it is/was important/necessary/essential/suggested/requested/ordered etc. +that clause.”e. g. He said it was important that every member (should) send his subscription by the end of the month. It is necessary that he (should) be sent there at once. It is requested that Miss Cai (should) give a performance at the party, 4. in the construction it is (high) time that and after would rather/preferetc.e. g. Its time that we went to bed. I would rather he came next Saturday. I would prefer you had seen the film.5. in some expressions or sentences for blessinge. g. Long live world peace!Heaven help us!May the friendship between our: two peoples last forever. Oh, if he only knew how we miss him! He is, as it were, a walking dictionary.6. in some special cases e. g. But for your help, we could not have finished the work in time. Without music, the world wouldbe a dull place.He took his raincoat with him!lest it should rain.He put his coat over the child for:fear that (lest) he should catch cold.Heres some money in case you!should need it. She stayed at home for a few days so that she might (could) take care of her mother. He would have given you more help, but he has been so busy. Suppose/Supposing it rained, we would still go.
