问题     It will come as no surprise that the earth is going to be a much more crowded place in the next century. From a global population of about 5. 4 billion today, the United Nations Fund for Population Activities says we’ II see a rise to 8. 2 billion people in 2025. The U. N. expects the total population to stabilize (稳定) at Il. 6 billion sometime later in the 2000 s.
    More than ninety percent of the population growth will occur in developing countries. Eighteen of the world’ s twenty largest cities will be in these lands as the number of urban-dwellers (城市居民) swells from roughly two billion to 5.1 billion. The Unites States and Europe, which in 1950 accounted for twenty-two percent of the world’ s population, will be home to less than nine percent of its people in 2025. By contrast, Africa’ s share of the total will climb from nine percent in 1950 to nearly twenty percent by 2015. Ethiopia should double in size to almost 100 million people. In about the same time period, India will overtake China as the world’ s most populous country.
    For the United States, the big news won’ t be an abundance of new faces; experts predict the country will grow from its present 250 million population and stabilize at about 350 million sometime before the middle of the 21st century. The important changes will be in American ethnic (种族的) makeup. Twenty years from now, the United States white, non-Hispanic majority will peak at 195 million, and then may decline in numbers. Asian-Americans will become an increasingly important minority, while African-Americans--whose population growth rate is slowing dramatically--will become the second-largest minority behind Hispanics, a half million of whom are now thought to be emigrating to the United States legally and otherwise, each year.
Which of the following statements is true according to the passage?

选项 A、Hispanics are the largest ethnic group in the United States.
B、All Hispanics in the US are thought to be legal immigrants.
C、Though slowing in population growth, African-Americans will still become the second largest minority in the US.
D、The white, non-Hispanic majority in the United States of America will always decrease in numbers twenty years from now.

答案C

解析 细节题。可分别对各选项进行定位。选项A定位于第三段最后一句前半部分African Americans...will be come the second-largest minority behind Hispanics可知Hispanics是美国最大的少数民族而不是最大的民族。选项B定位于最后一句后半部分a half million of whom are now thought to be emigrating to the United States legally and otherwise,故为误。选项C与A定位在一个地方,可判断该选项正确,选项D定位于第三段倒数第二句“Twenty years from now, the United States’white,non-Hispanic majority will peak at 195 million,and then may decline in numbers.”故D为误。答案为C。
