【正文】 local flavor? First and foremost, local residents must implement sustainable tourism with longterm tactics for economic development and not invite the type of tourism which allows outside investors to quickly take control of an area. Sustainable tourism allows for the preservation and protection of local resources. In reality, the more aware a munity is of its unique assets, whether cultural, architectural, or natural, the more visitors it will draw. 6. Fresh drinking water is being a scarce and all too expensive modity in many parts of the world. Discuss the causes and give suggestions for how to ensure adequate water supply for the world’s inhabitants. The words of Samuel Taylor Coleridge are revealing when we ponder the issue of water scarcity: “Water, water everywhere”, as the Ancient Mariner said, “ Nor any drop to drink”. It would seem that one of the biggest threats to supplies of fresh drinking water is that, at least in the rich West, it is largely taken for granted. In any case, it is the most frequentlyoccurring substance with most of the earth’s surface being covered in H2O. Our toughest challenge of the 21st century may not be pandemic diseases such as AIDS or the threat of nuclear war, but may in fact turn out to be a lack of fresh water. If we are not careful, the possibility of water wars in the future may outstrip our reasons for warring on nations who control other naturally occurring resources such as oil. At present many people lack access to clean water and even more people lack access to proper sanitation。 nearly all of them reside in developing countries. A continuation in population growth, environmental pollution and climatic changes are all likely to contribute to a devastating decline in water supply in the ing years. Similarly, with rapid urbanization occurring all over, the possibility for concentrated waste matter to reach unmanageable proportions is also highly likely in many regions. Unless we take affirmative action to properly conserve and manage the world’s fresh water supplies, the effects of water scarcity will undoubtedly affect human health and the chances for survival for all of the earth’s inhabitants. Waterrelated diseases caused by ingesting contaminated water and vectorborne diseases, such as malaria, are spread by insects that use water to breed. Raising much needed awareness about the importance of fresh water supplies and what we can do to further conserve this precious resource will bee a top priority to everyone if we wish to survive. Science and Technology 1. In light of the technological route that education is on today there has been some speculation as to the role of teachers in future education. To what extent do you think teachers are being replaced by puters? Information and Communication Technology (ICT) is quickly playing an important part in teaching in schools and other educational institutions. As more and more subjects can be taught via the puter, there would seem to be less and less need for teachers to be present, as selfstudy and autonomous learning are encouraged with the assistance of a puter. However, puters will never replace teachers because technology is only a tool and can never replace the spiritual element of the teacher. Selfstudy and independent learning using technology is a means of teaching that can be highly effective for practice drills, the study of factual knowledge, or for pure rote memorization. For instance, puters can help students solve math exercises and memorize historic facts. This type of teaching reduces the need of the presence of a teacher. Online teaching or video conferencing allows a teacher to teach to a greater number of students, optimizing costs for schools. This is already happening at the university level where many universities are offering online degrees, for example. Such teaching is profitable to universities as it optimizes costs by increasing teacherstudent ratios. I t would therefore seem that technology is making the teacher more and more redundant. But a crucial element has to be considered with regards to ICT and teaching. Good teaching takes place when the learning is directly associated with our emotions. We learn best when what we are learning has a direct implication on what we believe and what we feel. The puter may municate concrete knowledge, but only the teacher is able to municate wisdom, to build selfconfidence, and to make one think creatively, which is a more important part of learning. Therefore, no matter how sophisticated technology bees, a teacher will always be needed, because only with the presence of the teacher is there true interaction. What will happen is that technology will not replace teachers. Instead, teachers will no longer be able to teach students by rote memory or drill type exercises. The puter will take care of that. The teacher will have to stimulate the minds and bring out the creativity in his or her students. The teacher will have to bee a better teacher, a real teacher. ICT will improve teaching, and force teachers to be better teachers。 it will never replace the teacher, it will only make him or her more important. 2. The younger generation is uptodate with new techniques and advances in science. They are often better able to make important decisions than their parents are. To what extent do you agree or disagree with this opinion? The NetGeneration is here and whether we like it or not younger generations are in a position to be able to make significant decisions that will affect us all. What causes this generation to be poles apart from its predecessors is not just its demographic force but that it is the first to mature surrounded by digital media. Computers can be found everywhere and digital technologies such as cameras, video games and DVDs are now monplace
