Advances in science and technology and other areas of society in the last 100 years have transformed the way we live as well as postponing the day we die. There is no better time to be alive than now. To what extent do you agree or disagree with this opinion? Model Response The last hundred years have seen rapid and dramatic developments in many areas, including medicine, transport, manufacturing and communications. Over that period our lives have changed in ways that our parents and grandparents could only have dreamed of, but the question we should ask is whether the world is a better place to live in as a result. There have clearly been many benefits. Advances in medical science have brought cures for once fatal diseases and this has significantly extended the lifespan we can expect. Information technology has allowed us to contact friends or colleagues worldwide at the click of a mouse. We can now gather information, manage our bank account or shop without having to step outside our home. In addition, labour-saving devices such as washing machines and microwave ovens have made everyday tasks much easier. However, the fact that life has improved in so many ways does not mean that all the developments have been positive. For example, the emphasis on acquiring the latest technology has made people increasingly materialistic. We also tend to lead more isolated lives than our parents did, with less concern for the elderly and other vulnerable people without the support they need. Among other serious problems we face are the drug culture, and the ever-present threat of terrorism. In summary, we have made great progress over the last hundred years but there are still many important issues to tackle. This may well be a better time to live than any previous age but hopefully the future will be better still. (268w) What approach does the essay follow?
