四川省蓬溪县2016高考英语阅读理解及书面表达练习（10） 阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。 A research by the National Center for Health Statistics is seen as an important confirmation of the “Hispanic mortality paradox(西班牙裔死亡率悖论).” On average, Hispanics outlive whites by 2.5 years and blacks by 7.7 years. Their life expectancy at birth in 2006 was 80.6 years, compared with 78.1 for whites, 72.9 for blacks and 77.7 years for the total population. The report shows that the Hispanic population has higher life expectancy at birth and at almost every age despite a socioeconomic status lower than that of whites. “Mortality is very correlated with income, education and health care access,” says Elizabeth Arias, author of the report. “You would expect the Hispanic population would have higher mortality, in line with the black population.” The Hispanic paradox has been documented for more than two decades, but this is the first time the government has had enough data to issue national numbers. Researchers are struggling to explain why Hispanics live longer. “We don’t know,” says David Hayes-Bautista, director of the Center for the Study of Latino Health and Culture at UCLA’s David Geffen School of Medicine. “We thought it was a problem in the data, but we can pretty much say this is real.” |
