(After a few minutes.)T:Are you ready?(Ss:Yes.)Please tell us the function of each of the underlined parts.Ss:They are all predicates.T:Right.Please tell me what can be used as Predicate according to these examples.One student,one sentence.S1:In the first sentence,its predicate is a transitive verb.S2:The predicate of the second sentence is an intransitive verb.S3:In Sentence 3 and Sentence 4,they have the same verblink verb.Their predicates are a link-verb plus a predicative.S4:The predicate of the fifth sentence is a phrasal verb.S5:The structures of the sixth and the seventh sentences are the same.Their predicates are an auxiliary verb plus a notional verb.S6:The predicates of Sentence 8 and Sentence 9 are a modal verb plus a notional verb.Step PracticeT:Now lets do some exercises.Fill in the blanks with the proper forms of the verbs in the brackets.You should pay attention to the tenses and the agreement between the Subject and the Predicate.Discuss them with your partners.A few minutes later,Ill check your answers.(Show the following on the screen.)Fill in the blanks with the proper verb forms:1.An iron and steel works,with some small factories, _ (be) to be built here.2.Every boy and every girl_ (wish) to attend the evening party.3.The crew _ (be) standing in different parts of the ship.4.One and a half apples _ (be) left on the table.5.The German and the English language _ (have) something in common.6.A variety of questions _ (be) put to the lecturer.7.Another five weeks_ (be) necessary for us to finish the work.8.What they have done_ (be) useful to the people.9.In the room _ (be) found a big table and a great many chairs. (A few minutes later.)T:Have you finished?Ss:Yes.T:Please give us your answer to each sentence and tell us your reason briefly if you can.One student,one sentence.Any volunteers?S7:1.The answer to the first sentence should be “is”.The reason is that its Subject is “an.works” and “iron and steel” are used as the Attribute,so we should choose a singular verb.S8:2.Though the two subjects are joined by “and”,they are each preceded by “every”.A singular verb is needed here.So we use “wishes”.Am I right?T:Do you agree with him,so?Ss:Yes.He is right.S9:3.Here we use “were” as its predicate.Because “crew” is a collective noun and should take a plural verb.S10:4.“One and a half” takes a plural noun but a singular verb,so we use “is” as its predicate.S11:5.I think its predicate should be “have”.When a singular noun is modified by two adjectives so as to mean two distinct things,the verb should be in the plural.S12:6.We choose “were”.Because the Subject is “questions”.S13:7.Its predicate should be “is”.Because plural expressions of time,distance,weight,value,ect.usually takes a singular verb.S14:8.When the Subject is expressed by a phrase or a Subject clause,the verb is generally in the singular.So we take “is” as its predicate.I remember I read a sentence “what we badly need here are teachers.”Is it right or worng?T:Its right.“What-clause” is used as Subject,if its predicative is a plural noun,we generally choose a plural verb as its predicate.Are you clear about that?Ss:Yes.S15:9.Im not sure of choosing “were” or “was”.Can you explain it to me?T:Generally speaking,here a plural verb is right.However,there is a strong tendency to use the verb in the singular form instead of the plural in the inverted construction when the first Subject that follows the verb is singular.So both “were” and “was” here are right.Have you any questions?(Teacher answers any questions raised by the students.)Step PracticeT:Now well do another practice.Look at the screen and choose a suitable modal verb for each blank.Have a discussion with your partner and write down your answers on a piece of paper.Well check them in a few minutes.(Show the following on the screen.)Choose the best answers:1.Tom failed to pass the exam.Because he didnt study as hard as he _.A.doesB.used toC.hasD.had2.I dont have to work tonight.Then_you like to go to the theatre with us?A.willB.wontC.wouldntD.do3.I thought you_like something to read.A.mayB.mightC.couldD.must4.I didnt see her yesterday.Oh,but you_.A.must haveB.ought toC.should haveD.cannot have5.When did you first visit New York?I think it_in 1978.A.must beB.should have beenC.may beD.must have been6.Why arent you swimming this weekend?Well,I didnt want to go alone,and no one_ with me.A.wentB.has goneC.had goneD.would go7.My sister never used to oppose me,but my brother occasionally_.A.didB.used toC.usedntD.didnt8.Oh,Jane,youve broken still another glass.You ought_when you washed it.A.be carefulB.to careC.have caredD.to have been careful9.Shall we go skating or stay at home?Which_do yourself?A.do you ratherB.would you ratherC.will you ratherD.should you rather10.His advice_ not be taken.A.was neededB.needsC.needD.is neededSuggested answers:1.B2.C3.B4.C5.D6.D7.A8.D9.B10.CStep TestT:Look at the sentences on the screen and well have a test.Choose the proper answer for each sentence and write down your answers on a piece of paper.Do it by yourself and well have a discussion about the answers later.(Show the following on the screen.)Choose the proper form of the verb for each sentence.1.When_again?When_,Ill let you know.A.he comes;comesB.will he come;will comeC.he comes;will comeD.will he come;comes2.She didnt remember_him before.A.having metB.have metC.to meetD.to having met3.Where is my pen?I_it.A.might loseB.would have lostC.should have lostD.must have lost4.They asked me to have a drink with them.I said that it was at least ten years since I_a good drink.A.had enjoyedB.was enjoyingC.have enjoyedD.have been enjoying5.I should very much like to have gone to that party of theirs,but_.A.Im not invitedB.I have not been invitedC.I was not invitedD.I will not be invited6.People who wont work should be made_.A.to workB.workC.workingD.to be working7.Billy has difficulty_the rest of the class.A.to keep up withB.to keep upC.keep up withD.keeping up with8.We must have a person_them _the house.A.see;buildB.see;to buildC.to see;buildD.to see;to build9.Did you have trouble with your car this morning?Yes,but I finally managed .A.to get it startedB.to get starting it
