解析：研究人员的目标体现在最后一句“The researchers are now analyzing three years of data from the wellness program to see if there are any longer-term effects（研究人员现在正在分析来自健康计划的三年数据，以了解是否有任何长期的影响）”，因此他们的目标就是看这个健康计划从长期来看是否有益，D选项正确。
原文：
Companies have long embraced workplace wellness programs as a way to improve worker’s health and reduce overall medical spending. Nearly all the studies to date have concluded that the programs save some money for employers. But a new study may suggest employers rethink those efforts. The study looked at the experience of 33,000 workers at Wholesale Club over a year. While workers who enrolled in the wellness program reported that they learned to exercise more and watch their weight, the research found no significant differences in outcomes like lower blood pressure or sugar levels and other health measures. And it found no significant reduction in worker’s health care costs. Yet there were some encouraging notes among those workers who adopted healthier behaviors. These alterations could later lead to better overall health and lower medical expenses. The researchers are now analyzing three years of data from the wellness program to see if there are any longer-term effects.
Questions 22 to 24 are based on the passage you’ve just heard. 22. Why do companies need to rethink about workplace wellness programs? 23. What is the major result of the study done at Wholesale Club? 24. What do the researchers aim to do in their future analysis?
