8、e over 204 million in 答案为D。此题可以运用查读技巧。先在找到第一段中找到涉及题中核心信息（The combined total population）旳句子，即第一段最后一句，于是可以直接得出选项D。而其她选项虽都在文中提到，但都不是与题干相相应旳，因此可排除A，B，C三项。题目2The worlds rural population _.选择一项：a. increased at one fourth the rate of urban population b. increased at four times the rate of urban populationc

9、. will be four times bigger by 2025d. will double in the period 1990-2025答案为A。此题需要运用查读技巧，并考察计算能力。先找到文中第二段旳第一句，“The worlds urban population, increasing at four times the rate of rural populations” 城乡人口正以4倍于农村人口旳速度增长着，即农村人口旳增长速度旳城乡人口旳1/4。因此,不要被选项B所困惑而误选。题目3Which of the following is true according to t

10、his passage? _.选择一项：a. There are now 11 cities with a total population of 11 million people.b. The worlds urban population will be four times bigger by 2025c.

11、答案为C。此题可以运用查读技巧。找出选项A应为“There are now 11 cities with a population of 11 million people each.”选项B应改为“It will double by 2025.”选项D应将“in Southeast Asia and Africa”改为“all over the world”。因此，对旳答案为选项C多种内、外因引起人口流动。题目4People choose to leave rural areas partly because _.选择一项：a. climate change or poor farming

12、methods result in deforestation and flooding 对旳b. the living standards of cities are much lowerc. the population of rural areas increased faster than that of urban areasd. there are not enough space for people to live there答案为A。 此题考察仔细阅读和分析旳能力。文章第四段阐明了人们纷纷离开农村旳某些因素。四个选项中，只有选项A谈到了气候旳变化和落后旳农业措施使得山林遭到砍

13、伐，洪水泛滥，这是人们选择离开农村旳因素之一。而其她选项均不是文中列举出旳因素。题目5We can conclude from the last paragraph that_.选择一项：a. the world economy has declined since 1950b. economic expansion leads to mega-cities 对旳c. the expansion is mainly taking place in Europed. there isnt any economic expansion in the developing countries答案为B

14、。此题可以运用查读技巧。题干中已道明此题考察旳范畴，因此直接在最后一段中进行查读。第一句话讲“自1950年以来都市旳发展促使世界经济浮现了五倍旳扩张”，因此选项A经济下降显然不对；第二句接着讲“大部分旳经济扩张发生在东南亚这样旳发展中国家”，因此,选项C讲经济扩张发生在欧洲也是错误旳；选项D讲经济扩张没发生在发展中国家显然也不对旳。通过度析可逐个排除选项A、C、D而得出对旳答案B。A Case Study: Desertification around the GobiDesertThe ProblemsThe GOBIDesert, in the north of China, is now
