Teaching goals 教学目标1. Target language目标语言Learn the Grammar — Reporting2. Ability goals能力目标Enable students to use the reporting verbs freely.3. Learning ability goals学能目标By practicing enable students to use reporting verbs freely.Teaching important points教学重点Patterns of reporting verbsVerb+ thatVerb +someone +thatVerb + (not) doing somethingVerb + (not) to do somethingVerb + someone (not) to do somethingVerb+ (someone) +preposition + (doing) somethingStep I RevisionAsk students to pick out the reporting verbs used in the text.Step II GrammarDeal with Ex 6-7 on page 7. From this exercise students will have a better understanding of the function of reporting verbs. Then read Grammar Summary 1 onpage 100. After reading Grammar Summary 1, continue to do the rest of grammar exercises.T: In Grammar definitions, you will find a summary of basic reported speech. This most commonly involves using the verbs say, tell and ask, as well as changes of verb tenses, times, places and pronouns: (Show the following on the PowerPoint.)"I am going to the shop."He said (that) he was going to the shop."Sit down and open your books."She told us to sit down and open our books."Will you come with us tomorrow?"He asked me if I would go with them the following day.A native speaker of English, however, will often use reporting verbs other than just say, tell and ask. Compare the following:"I didn't do it!"He said that he hadn't done it.He denied that he had done it OR He denied doing it."I'll bring the book back tomorrow."She said that she would bring the book back the following day.She promised to bring the book back the following day."Please will you think about it some more?"He asked me if I would think about it some more.He begged me to think about it some more."First you should put the money in the slot and then you should press the button."She said that I should first put the money in the slot and then press the button.She explained what I should do.Notice that different reporting verbs are followed by different structures, i.e.deny + that-clause ORdeny + -ing formpromise + infinitivebeg + object + infinitiveSUMMARY OF REPORTING VERBSNote that some reporting verbs may appear in more than one of the following groups.1. Verbs followed by 'if'or 'whether' + clause:ask know remember say see2. Verbs followed by a that-clause:add admit agree announce answer argue boast claim comment complain confirm consider deny doubtestimateexplainfearfeelinsistmentionobservepersuadeproposeremarkrememberrepeatreplyreportrevealsaystatesuggestsupposetellthinkunderstandwarn3. Verbs followed by either a that-clause or a to-infinitive:decide expect guarantee hope promise swear threaten4.

Verbs followed by object + to-infinitiveadvise askbeg command forbid instruct inviteteachtellwarnStep III PracticeDeal with grammar Ex 8-10 on Page 7. Students should do the exercises individually first, then check the answers with the whole class. Deal with the grammar Ex 1-3 on Page 52 and Ex 6 on Page 53 in the same way.Examples:Jack encouraged me to look for a new job.They invited all their friends to attend the presentation.She offered to give him a lift to work.My brother refused to take no for an answer.Tom admitted (that) he had tried to leave early.She agreed (that) we needed to reconsider our plans.He denied having anything to do with her.Ken suggested studying early in the morning.Ken suggested that we (should) study early in the morning.Mr. Smith advised to set off early.Mr. Smith advised us setting off early.Mr. Smith advised that we should set off early.They accused the boys of cheating on the exam.She blamed her husband for missing the train. He apologized for being late.She insisted on doing the washing up.He apologized for being late.She insisted on doing the washing up.Step V Homework1. Go over the grammar in Unit 22.2.
