问题 Tests have proved that caffeine affects the body by increasing the heart rate and rhythm, which______ affects the circulatory system.
选项 A、in the long run
B、in turn
C、in return
D、as a result
答案 B
解析 这是一道近形词组的辨析题，in turn表示“反过来”；in the long run，“从长远观点看”：as a result意为“结果”： in return意为“作为回报”。本句讲的是咖啡因使心率加快，而心率加快又会影响循环系统疾病，谈论“心率和循环系统疾病的关系及相互作用”，不仅仅是结果，所以B是最佳选择。
