| C | Dialogues | Skills |
| C | Let¡¦s get started. | Initiate the discussion |
| C | Today we are going to have a discussion on genetic engineering. First of all, we have to discuss food engineering. | State the situation |
| C | Food engineering is very common nowadays. Many foods are genetically modified. | Raise a point |
| D | For example, corn, Soya beans, milk powder and bean curbs. | Extension |
| B | Yes. We can easily buy some from the supermarket. But people may not know what GM food is. | Agreeing |
| A | Even people know what GM food is, they cannot distinguish them while shopping in the supermarket. There is no distinct labeling on those foods. | Extension |
| D | Yes. I think labeling on r GM food is essential as they have several drawbacks. | Raise a point |
| C | Do you mean that GM food can cause illnesses? | Raise a question |
| D | What you say is partially right. Although there is no medical evidence about the harmful effects of GM food to human, the quality and safety are still doubtful. | Clarification |
| B | You are right. Some professionals even suggest that GM food may cause cancers. | Agreeing |
| A | The safety of GM food is questionable. Some people may think that GM food is a tool for scientists to make money. People are always afraid that scientists will use GM food to make money at the expense of consumers¡¦ health. | Extension |
| B | Besides, ethical problems may be caused by GM food. It is against nature, as the crops¡¦ genes are artificially modified. | Raise a point |
| D | However, GM food also has its advantages. | Transition |
| D | With the technology of gene modification, crops can have better yields. | Raise a point |
| B | Increasing yields can alleviate the problem of food shortage in some developing countries, such as Africa. | Explanation |
| A | In the developing countries, the population is increasing, so as the demand for food. Food shortage occurs. This leads to famine. | Extension |
| C | Infant mortality is high. Children there may have malnutrition too . Diseases that causes by malnutrition include iron deficiency anemia and vitamin Deficiency are very common in those countries. | Extension |
| D | With the use of GM food, productivity can be raised. The nutrient content of the food can also be enriched. The above problems can be solved then. | Raise a point |
| A | Do you still have something to add? ¡KIf you do not have, let¡¦s talk about human and animal cloning. | Transition |
| A | I think animal cloning has many advantages. For example, scientists can do research on the cloned animals. | Raise a point |
| D | Sorry, I can¡¦t follow. Do you mean that scientists can make use of the cloned animals to do medicine testing? | Raise a question |
| A | Yes. Tests can be done on cloned animals, not human. It can ensure the medical safety for human. | Clarification |
| B | Sometimes, we can take the skin or organs of cloned animals for the patients. Many patients are waiting for the organ donation. However, merely few of them can get the organs donated. Then, they may get the necessary organs from animals instead. | Raise a point |
| C | But will it be too cruel for the animals? | Raise a point |
| B | Um¡K Although it may be the case, we have no choice sometimes. | Clarification |
| D | Yes. | Agreeing |
| B | Animal cloning also has its drawbacks. It is too cruel to kill the animals for the organs only. | Raise a point |
| A | They may feel painful or even die during the process of animal testing, too. | Raise a point |
| C | Yes. How about human cloning? I think it also has drawbacks. | Transition |
| C | In my opinion, It is unethical to practice human cloning. | Raise a point |
| D | Yes. It is strange to ¡§produce¡¨ two identical persons . | Extension |
| A | The identity of
the cloned person will be doubtful. Who is his/ her parents? Is he/ she a ¡§real¡¨ person? |
Explanation |
| B | The relationship between people will be worsen or out of order, as many people with no identity are produced. | Extension |
| A | There is the other side of the coin. There are also advantages of human cloning. | Transition |
| A | With human cloning, organs or special substances can be extracted to transplant to their ¡§families¡¦ members¡¨ for treatment. | Raise a point |
| C | You are right. Many special diseases can be cured with cloned human. | Agreement |
| B | Human and animal cloning have their advantages and disadvantages. Let¡¦s talk about future development of the genetic engineering in the 21st century. | Transition |
| B | In my opinion, the development will be continued. The techniques of genetic engineering will be more advanced. | Raise a point |
| D | In my opinion, more cloned animals will be produced for medical development. | Extension |
| A | With the improvement of technology, human cloning will become possible and easy. New regulations will be introduced for the production of cloning. | Raise a point |
