2、where relevant.Write at least 150 words.2 You should spend about 40 minutes on this task. Write about the following topic. The exploration and development of safe alternatives to fossil fuels should be the most important global priority today. To what extent do you agree or disagree? Give reasons fo
3、r your answer and include any relevant examples from your own knowledge or experience. Write at least 250 words. 雅思（写作）模拟试卷 75答案与解析 1 【正确答案】 The table shows dramatic increases in the total world population from 2.5 billion in 1950 to 6 billion in 2000, with an expected increase to 9 billion in 2050.
4、 However, this trend is affecting parts of the world differently. Throughout the period Asia is expected to retain the largest share of the world population(56 to 59%)so their population will probably continue to increase in line with world growth. Meanwhile, regions like Africa and Latin America ha
5、ve experienced similar rates of increase in their populations up to 2000(4% and 3% of the total, respectively), but Africa is expected to grow much faster as it rises to 20% of the total by 2050. In contrast, more industrialised regions saw a large fall in their proportion of the global population,
6、from almost a quarter in 1950 in Europe to only 12% by 2000 and from 7% to 5% in North America. This decline is expected to continue to a mere 11% of the total in both regions together by 2050. Overall the figures suggest that population increases will continue in less developed regions, but not in
7、the more industrialised ones. 2 【正确答案】 It is true to say that fossil fuels are still our main source of energy today, and as more countries develop their industries and their economies, the scale of their use continues to grow. However, we are now well aware of the consequences of relying on this en
8、ergy source for our natural environment. Global warming and the damage to the protective ozone layer are caused by carbon dioxide and other by-products of fossil fuels. So I certainly agree that these problems are global rather than national ones. They threaten our whole planet and no action by a si
9、ngle country could solve them. Furthermore these problems are urgent as nobody knows when our natural world will be so damaged that it will no longer be able to support us. While some countries already use safer alternative energy sources, such as wind, water or solar power, it seems that there has
10、not been sufficient investment in developing the technology to make such alternatives viable for all. So it should definitely be a global priority to invest in such research and development. Of course there are other global priorities that we also need to address, such as poverty and disease. But wh
11、ile it may be the case that these problems are just as important as the energy problem, there is a sense that time is ticking away for our planet and any solutions to the energy issue will take some time to achieve. So in conclusion, I would agree that finding alternatives to fossil fuels is certainly the most pressing global priority, if not the most important one for our world today.
