10、mmigration, emigration and net migration of labor force between 1999 and 2008. （分数：30.00）_正确答案：()解析：Migration in the UKIt is generally acknowledged that labor force involves high-skilled workers and low-skilled workers. Dual labor market theory assumes that migration between developed and less devel

11、oped countries is caused by pull factors needed. However, a survey about migration between 1999 and 2008 in the UK shows a different picture during Tony Blairs 10 years in office between 1997 and 2008 when there were successive quarters of economic growth. From the line graph, the number of immigrat

12、ion and emigration both rose over the period, but the figures for immigration were considerably higher. In 1999, over 450,000 people came to work in the UK, while the number of people who emigrated stood at just under 300,000. Till 2004, the number of immigration rose by nearly 150,000 people, and t

13、he emigration increased slightly too. After 2004, the rate of immigration continued to climb high, but the number of emigrants fluctuated, falling suddenly in 2007, before peaking at about 420,000 people in 2008. As a result, the net migration figure fluctuated with them, first standing at around 16

14、0,000 in 1999, peaking at almost 250,000 people in 2004, then standing at around 240,000 in 2007, but falling back to around 160,000 in 2008. In conclusion, looking at this line graph, we can see that the migration from developed countries to less developed ones does not have a very direct relation-

15、ship with economic growth and skills required. 解析 所给材料短文提出移民(包括移到其他国家和移入)的劳动力市场论这一移民理论，并提出技术劳动力成本对移民的重要影响。而图表则提出布莱尔当政期间经济快速发展时移民的变化。因此，可以使用图表数据来论说材料短文中的理论。2.You are doing a mini research project on the age when people get marriage. The following are some useful materials. Write a report of about 200

16、 words. Your report should mainly be made up of two parts. In the first part, you describe the graph. In the second part, you analyze the relevant situation. You should also provide an introduction and conclusion for your report. Marks will be awarded for content relevance, content sufficiency, orga

17、nization and language quality. Failure to follow the above instructions may result in a loss of marks. GraphThe chart gives information about the average age when men and women got first marriage in America between 1890 and 2010. （分数：30.00）_正确答案：()解析：The Marriage AgeThe age of getting married is kno

18、wn to be closely connected with the youth of a society. If people are getting married older and older, it will drive our society into an aging one. So it is very important to track the marriage age during a long term. From the given chart, during the years of 1890 to 2010, American men and women ten

19、ded to wait longer than ever to get married while men seemed to marry at an older age than women. In 1890, men married under 27 while women married below 24. Both the married age figures declined during the following 50 years and reached the lowest in 1950, men at 24 and women at around 21. Since th

20、en, the median age at first marriage rose rapidly though mens age remained the same at 24 between 1950 and 1970. When it came to 2010, we were at an all-time high of 28.5 for men and 27 for women. It is said that why people get married late involves the financial factor and young peoples attitude to

21、wards marriage. But from the graph, it is very hard to identify there is any direct relationship between these two factors and late marriage of men and women. 解析 图表描述了美国在1890年到2010年期间男女结婚的平均年龄的变化趋势，而材料短文则提出当前不婚的原因，尤其是在美国，不婚是受到经济压力和文化变化的影响。因此，在写作的过程中，考生要使用图表所提供的数据论证晚婚这一现象，但是否和经济压力和文化变化有关，不能直接得出这类结论。3

22、.You are doing a mini research project on diets. The following are some useful materials. Write a report of about 200 words. Your report should mainly be made up of two parts. In the first part, you describe the graph. In the second part, you analyze the relevant situation. You should also provide a

23、n introduction and conclusion for your report. Marks will be awarded for content relevance, content sufficiency, organization and language quality. Failure to follow the above instructions may result in a loss of marks. GraphThe pie charts compare the proportion of carbohydrates, protein and fat in

24、three different diets. （分数：40.00）_正确答案：()解析：A Healthy DietA healthy diet has long been said to be important in our lives. A well-balanced diet can reduce the risks of many diseases, and can even postpone our aging process. It even shows different ingredients to different groups of dieters. So how fa

25、r the difference among diets is can be found in the following graph. The three pie charts present the percentage of carbohydrates, protein and fat in three different diets, namely an average diet, a healthy diet, and a healthy diet for sport. It is clear that a diet for sports has a relatively highe

26、r amount of carbohydrates than an average diet or a healthy diet. However, the average diet contains the lowest percentage of carbohydrates but the highest proportion of protein. To be more specific, carbohydrates make 60% of the healthy diet for sport, which is 10% higher than those in a healthy di

27、et, and 20% more than in an average diet. On the other hand, only 25% of the sports peoples diet is protein, with a healthy diet increasing by 5% and an average diet rising by 15%. Fat constitutes exactly one fifth of both the average diet and the healthy diet, but the amount drops to only 15% for the healthy sports diet. In conclusion, to keep healthy, we should rely on a diet consisting of more carbohydrates, relatively less protein and even much less fat. 解析 健康饮食一直都是被广泛推广的，所给材料具体解释了健康饮食带来的好处，而图表则是提供三类饮食的构成对比，主要比较碳水化合物、蛋白质和脂肪的比例。因此，我们要在文章首段提出健康饮食的重要性，其次使用图表信息来描述健康饮食的构成，从而得出怎样的饮食才是健康饮食的结论。
