Life expectancy in the United States has been in decline for the first time in decades, and public health officials have identified a series of potential causes, including inaccessible health care, rising drug addiction and rates of mental health disorders, and socio-economic factors. Now, a study led by the Yale School of Medicine has attempted to find out the relative impact of two factors most often linked to life expectancy – race and education – by looking at data about 5,114 black and white participants in four U.S. cities.

The lives and deaths among this group of people – who took part in the study approximately 30 years ago when they were in their early 20s – show that the level of education, and not race, is the best predictor of who will live the longest.

Among the 5,114 people followed in the study, 395 had died. These deaths were occurring in working-age people, often with children, before the age of 60. The rates of death among participants in this group did clearly show racial differences, with approximately 9% of blacks dying at an early age compared to 6% of whites. There were also differences in causes of death by race. For instance, black men were significantly more likely to die of murder and white men from AIDS. The most common causes of death across all groups over time were cardiovascular disease and cancer.

But there were also obvious differences in rates of death by education level. Approximately 13% of participants with a high school degree or less education died compared with only approximately 5% of college graduates.

Strikingly, when looking at race and education at the same time, the researchers found that differences related to race almost disappeared: 13.5% of black subjects and 13.2% of white subjects with a high school degree or less died during the course of the study. By contrast, 5.9% of black subjects and 4.3% of whites with college degrees had died.

Therefore, improving overall quality of education is something tangible that can help reverse (扭转)this troubling trend in reduction of life expectancy among middle-aged adults.

1.What can we learn about the participants in the study?

A.The whites are more aggressive.

B.The whites got higher education.

C.More blacks than whites died young.

D.More whites than blacks died of cancer.

2.Compared with education, the influence of race on death rates is 　　　　　 .

A.significant B.unnoticeable

C.growing D.long-lasting

3.What does the underlined word “tangible” probably mean?

A.Realistic. B.Creative.

C.Challenging. D.Temporary.

4.What can be inferred from the research findings？

A.People can get smart through learning.

B.One should not discriminate other races.

C.People don’t enjoy equal rights for education.

D.One can live longer by getting more education.
