7、.Why is this occurring？Nobody is quite sure，but poor diet and above all long-time alcoholism have much to do with it.If current trends dont bend，Russias population will be about the size of Yemens by the year 2050.In the north of India，the population is booming due to high birth rates，but in the sou

8、th，where most economic development is taking place，birth rate is falling rapidly.In a further twist，birth rate is highest in poorly educated rural areas and lowest in highly educated urban areas.In total,25% of Indias working-age population has no education.In 2030，a sixth of the countrys potential

9、work force could be totally uneducated.One solution is obviously to import foreign workers via immigration.As for the USA，it is almost unique among developed nations in having a population that is expected to grow by 20% from 2010-2030.Moreover，the USA has a track record of successfully accepting im

10、migrants.As a result its likely to see a rise in the size of its working-age population and to witness strong economic growth over the longer term.考场思维模式第一步：读表格，知文章大意通过略读树状图，可知本文话题是“人口下降” ，并且分析了几个国家存在的人口问题。第二步：定位，定词，定性，定形任务型阅读树状图高度概括了原文信息，为了节约时间并且提高解题的针对性，先读图中的内容，然后在原文中进行定位，定位后进行定词，定词后定性(如名词、动词、形容词、
