    The results were recently published in the Proceedings of the National Academy of Sciences ( PNAS). The study involved 1. 2 million Swedish men doing military service who were born between 1950 and 1976. The research group analyzed the______【52】of both physical and IQ tests the youngsters took right after they started serving the army.
    The study shows a clear link______【53】good physical fitness and better results for the IQ test. The strongest links are for______【54】thinking and verbal comprehension.

"Being fit means that you also have good heart and lung______【56】and that your brain gets plenty of______【57】, " says Michael Nilsson, professor at the Sahlgrenska Academy and chief physician at the Sahlgrenska University Hospital. "This may be one of the reasons______【58】we can see a clear link with fitness, but not with muscular______【59】. We are also seeing that there are growth factors that are important. "
    By analyzing data for twins, the researchers have been______【60】to determine that it is primarily environmental factors and not genes that explain the link between fitness and a______【61】IQ.
    " We have also shown that those youngsters who______【62】their physical fitness between the ages of 15 and 18 increase their cognitive performance, " says Maria Aberg, researcher at the Sahlgrenska Academy and physician at Aby health centre. "This being the case, physical______(63 ) is a subject that has an important place in schools, and is an absolute must if we want to do well in maths and other theoretical subjects. "
    The researchers have also compared the results from fitness tests______【64】national service with the socio-economic status of the men later in ______【65】. Those who were fit at 18 were more likely to go into higher education, and many secured more qualified jobs.
选项 A、capacity
B、disease
C、shape
D、treatment
答案A
解析 由于“Being fit means that you also have good heart and lung______”说的是，健康意味着心肺功能好，所以选项B．disease疾病和D．treatment治疗，可以排除，而good heart and lung后若接shape形状，意思是“好的心肺形状”，这与健康的关系也远了一些。本题只有A．capacity(能力)才是合适的答案。
