2019-2020年高中英语（人教大纲）第二册下：Unit18 Inventions(第五课时)Teaching Aims:1.Revise the Attributive Clause,including the Restrictive Attributive Clause and the Non-restrictive Attributive Clause.2.Revise the use of relative pronouns and relative adverbs.3.Expand the knowledge of the Attributive Clause.Teaching Important Point:The usage of the relative pronouns and adverbs.Teaching Difficult Point:Help the students to master the way of choosing a relative pronoun or a relative adverb correctly.Teaching Methods:review,explanation,inductive methodsTeaching Aids:1.the blackboard2.the multimediaTeaching Procedures:CStep GreetingsGreet the whole class as usual.CStep Revision and Lead-in(Teacher checks the homework exercises first and then shows the following on the screen.)1.He is a famous scientist.2.Whos that girl in red?3.Ive read all the books that you lent me.4.I have lost my pen,which I like very much.T:Thats all for the homework.Now please look at the sentences on the screen.Pay special attention to the underlined parts.Is there anything in mon between them?Ss:Yes.They all identify the nouns,which are used with them.Each part tells us which thing or person the speaker is talking about.T:That is to say,the function of each underlined part is the same.Each of them is used as an attribute to describe each noun.Well,are there any differences between them?S1:Yes.In the first sentence,the attribute is an adjective and put before the noun;the second is a prepositional phrase put after the noun;the third and fourth sentences are full sentences put after the nouns.T:You are right,what do we call the sentences put after the noun?Ss:The Attributive Clause.T:Quite right.In a plex sentence,the clause modifying a noun or a pronoun in the main clause is called an Attributive Clause.The noun or pronoun is called Antecedent.The word that/which introduces the clause(between the noun/pronoun and the clause)is called Relative Pronoun or Relative Adverb.The relative pronouns or adverbs do two jobs at once.They can be used as subjects,objects,attributes or adverbials in the clause;at the same time,they join clauses together.About the use of them,well have particular revision after a while.Now look at the sentences on the screen.(Teacher shows the following on the screen.)plete the sentences with suitable relatives.1.I know the reason_he came late.2.Do you know the woman,_son went to college last year?3.The house_colour is red is Johns.4.This is the best film_Ive ever seen.5.That is the town_he worked in 1987.T:Whod like to tell me what should be filled in the first sentence?S2:I think“why”should be filled.Because the antecedent is“the reason”and the relative is used as the adverbial of reason in the Attributive Clause.T:Yes.How about the second sentence?(Teacher goes to another student and asks her/him to answer.)S3:I fill“whose”here.Because the antecedent is “the woman”and the relative is used as the attribute in the Attributive Clause.T:Right.Sit down,please.Now lets look at the third sentence.Suggested answers:3.whose 4.that 5.whereCStep Summarize the Use of the Non-restrictive Attributive ClauseT:The Non-restrictive Attributive Clause is a clause which gives extra information to the antecedent.So we use a ma to interrupt the sentence.When the Non-restrictive Attributive Clause is cut off,the sentence still has a full meaning.Now look at the sentences on the screen.(Show the following on the screen.)1.I have two brothers,who are both soldiers.2.Next week,which youll spend in your hometown,is ing.3.Ive tried two pairs of shoes,neither of which fits me well.T:Pay attention to the underlined parts.There are mas to interrupt the sentences and “that”can not be used in the Non-restrictive Attributive Clause.You should pay more attention to the structure“Indefinite Pronoun/Numbers/Noun/Superlative+of which/whom”is often used in the Non-restrictive Attributive Clause.CStep The Usage of the Relative Pronouns and the Relative AdverbsT:As we know,relative pronouns or adverbs paly important parts in the Attributive Clause.Now lets make a list of them on the blackboard first and then revise their usage with the help of the forms on the screen.(Bb:the relative pronouns:who,whom,that,whose,which;the relative adverbs: when, where, why)(Teacher collects them first and then shows the following.)Form 1:the relative pronounsreferring tofunction in the clausewhopeoplesubject/objectwhompeopleobjectthatpeople/thingsubject/objectwhichthingsubject/objectwhosepeople/thing(of whom/which)attributeForm 2:the relative adverbreferring tofunction in the clausewhen(=at/in/on which)timeadverbial of timewhere(=in/at which)placeadverbial of placewhy(=for which)reasonadverbial of reason(Teacher explains the two forms separately and adds the following with examples on the screen.)T:1.When a relative pronoun is used as a subject in the clause,the verb must agree with the antecedent in person and number.e.g.1.Those who want to go to the cinema must be at the school gate by 3:30 p.m.He who doesnt reach the Great wall is not a true man.2.When the antecedent is the structure of “one of +n.(pl.)”,the verb in the clause must be plural,agrees with the plural form.However,if there is “the”or“only”before“one”,the verb in the clause must be singular,agrees with the word“one”.e.g.2.She is the only one of the girls who has been to Beijing.He is one of the boys who have seen the film.3.When the antecedent is a noun for time or place “when”or“where”is not always used to introduce the clause.It depends on the function of the relative word in the clause.e.g.3.The time when/that I went to Tokyo is in 1982.Ill never forget the time which/that I spent at college.The shop which I bought is big.The shop where/in which I bought the book is big.CStep The Difference Between “that”and “which”T:As we know,both“that”and “which”can be used for things,but,the use of them are not always the same.Lets look at the sentences on the screen.(Show the following on the screen.)1.This is the second article that I have written in English.2.It is the best film that he has ever seen.3.This is the very book that I want to read.4. All that they told me surprised me.5.They talked about the teachers and schools that they had visited.6. Who is the rade that was there?7.There is a bed in the room that is still vacant.8.Our village is no longer the place that it used to be.T:From the sentences on the screen,we can make a summary of the use of“that” and “which”.Look at the screen again.(Show the following on the screen.)1.In following cases,“that”is often used.(1)After ordinal number and superlatives.(2)After the following words:all, only, little, few, much, very, none, last, just, any(thing), every(thing), some(thing),no(thing).(3)After two or more antecedents,referring to both people and things.(4)After interrogative pronouns“which”or “who”.(5)When the relative pronoun is used as a predictive in the clause.(6)When the main clause begins with “There be”.2.In following cases,“which”is always used.(1)After prepositions.(2)To introduce a Non-restrictive Attributive Clause.(3)The whole main sentence is the “antecedant”of the relative clause,and there is always a ma.CStep PracticeT:Now lets do some exercises.Look at the screen.Fill in the blanks,choosing proper relative pronouns or relative adverbs.(Show the following on the screen.)1.Tell me the reason for_you were late for class.2.Who is the girl_is speaking there?3.This is Mr Smith,_has some thing interesting to tell you.4.The puter_CPU doesnt work has to be repaired.5.This kind of puter,_is well-known,is out of date.6.This is just the place_Ive been longing to visit for years.7.His mother is an engineer,_makes him very proud.8.The old man has four sons,three of_are doctors.Suggested answers:1.which 2.that 3.who 4.whose5.which6.that7.which8.whomCStep TestT:Now.Lets have a test.Look at the screen.Do this exercise by yourself.A few minutes later.Ill give you the answers.(Show the following on the screen.)1.I dont like the way_he talked to his mother.A.as B.thatC.whichD.by which2.In the dark street,there wasnt a single person_she could turn for help.A.thatB.whoC.from whomD.to whom3.The weather turned out to be very good,_was more than we could expected.A.whatB.whichC.thatD.it4.All_is needed is a supply of oil.A.the thingB.thatC.whatD.which5.He paid the boy $10 for washing the windows,most of_hasnt been cleaned at least a year.A.theseB.thoseC.thatD.which6.She spoke about the books and writers_she remembered.A.thatB.whoC.whichD.whom7.The clever boy made a hole in the wall,_he could see what was going on inside the house.A.in whichB.through whichC.at whichD.on whichSuggested answers:1.B 2.D 3.B 4.B 5.D 6.A 7.BCStep HomeworkReview the Attributive ClauseCStep The Design of the Writing on the BlackboardUnit 18 InventionsThe Fifth PeriodThe Attributive Clause.The differences between the Restrictive Attributive Clause and the Non-restrictive Attributive Clause.The use of the relative words:1.relative pronouns:who,whom,whose,that,which2.relative adverbs:where,when,why.The differences between“that”and “which”CStep Record after Teaching
