III.Ứng dụng câu bị động vào IELTS speaking and Writing.
- Speaking : Topic “ Animals”
Question 1 : Should animals be used in research?
Well, you know, it is said that the use of animals in scientific research has long been the subject of heated debate. On one hand, it is considered morally wrong to use animals in this way solely for human benefit. Human beings, in fact, have no right to interrupt in animals’ survival.
Question 2: Did you have any pets when you were a child?
Yes, my father got a dog for us as we were child. But, I remember he was so aggressive that we rarely played with it. He used to be kept in our yard for guarding the house. However, later on when he started recognizing us he allowed us to come near him. I remember, my brother actually bonded a lot with him and so when he died it was a true shock for my brother.
- Writing task 2
Question: Genetic engineering is an important issue in society today. Some people think that it will improve people’s lives in many ways. Others feel that it may be a threat to life on earth. Discuss both these views and give your own opinion.
→ It is said that genetic engineering is a key area of modern scientific research, with broad implications for all human societies. While I accept that this field of technology may have its dangers, I believe that the benefits of genetic engineering outweigh the drawbacks.
The negative implications of genetic engineering are often discussed in terms of two key areas, which are food production and the cloning of humans. Genetically modified crops are already being grown, and people are concerned that they may damage whole ecosystems as foods become resistant to diseases and natural predators. But perhaps even more worrying is the possibility that humans could be modified or cloned. Some people imagine a world in which cloned humans are used to fight wars or to provide body part replacements. Although perhaps not a threat to life on earth, the implications of such practices would be unprecedented.
