Step Ⅲ Listening T：Now open your books at Page 42.Let's do some Listening.First Part 1.You're going to listen to a letter about Mekanika's life.Listen carefully and pay attention to the year when she is living，the place where she 1ives,the things that happened to the people on the earth and the reason why she is writing you this letter.Write down what you hear.At last I'll check the answers with you.Is that clear? Ss：Yes. T：OK.Let's begin. (Teacher plays the tape for the first time.Then plays for the second time，during which time teacher may pause for the students to write down the in-formation .Finally teacher checks the answers in Part l with the whole class.) T：Next listen to Part 2 and do the two exercises in them. (Teacher lets the students go through the Exx in Part 2 and then plays the tape for the students.At last check the answers.) Step Ⅳ Speaking T：NOW look at the picture in Speaking Part.There are two girls in the picture.One girl is working on the com-puter.The other is making a phone call.Can you find anything different between them? Ss：No.They are the same.Maybe they are twins. T：No，they aren't twins.One of them is cloned.With the development of tech-nology，scientists will be able to clone persons as well as animals.Suppose the year is 2089 and scientists have discovered how to make“doubles”，ex-act copies of a person that can do eve-rything the original can do.Now work in groups of four to discuss the question whether the new techno1ogy should be used.First give your opinion and tell the reason.Write it in your textbooks.After that make up a short dialogue, using the information in your books and the useful expressions on the blackboard. (Bb：It would be wonderful if… It would be bad for…if… It’s possible/impossible to predict… No one can predict what/when… Just imagine if… We can only guess…) (Teacher gives the students four mi-nutes to prepare in groups of four and then asks some groups to read their dialogues before the class.)
