work in groups of three or four, discussing which of the writers views you agree and disagree with. give reasons.a sample discussion:s1: we agree with the authors view on advertising. theres so much advertising which encourages young people to spend money. and many students visit shops in their free time instead of doing something useful or helpful, so i think advertising should be controlled.s2: i find many people are encouraged to buy something they neednt, just because they are on sale. sc: i agree with the writers view. we should visit the shops less and buy what we really need.s3: recently, fast consuming appears in some places. people buy and change clothes frequently, which will contribute to a waste of resource. so i think people shouldnt consumer blindly.t: oh, very good. we should remember that “being” and “doing” are much more important than “having” when we seek for beauty. we should also care about environment we live in.teacher can ask one or two more students to tell their opinions.step iv explanationduring this procedure teacher will play the tape for students. students will underline the difficult sentences. after listening to the tape, teacher will explain the text and deal with language problems.t: lets deal with some difficult language focuses. now i will play the tape for you. please make a mark where you have difficulties.after listening to the tape, explain the difficult sentences to students. before explain the difficult points, students are asked to refer to the notes to the text on page 116-117.t: do you have any difficulties with the text?s: could you please explain the sentence to us: its high time that we took these issues more seriously.t: first, lets analyze the sentence structure. in this sentence, the past tense should be used with took no matter what tense is used in “its high time that”. its high time that is a sentence pattern often used in the subjunctive mood and in the grammar part, we will learn about it in details and do more practice. do you have any other questions?
