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 turn
B、in return
C、turn back
D、as a result
答案A
解析 介词词组辨析。本题可先排除动词短语turn back“往回走，折返”；而in return表示“作为回报”，用在这里也不对：as a result意为“结果”，句中并没有原因出现，所以不合适。本题谈论咖啡因使心率加快，而心率加快影响循环系统，in turn表示“又(对别人)做同样的事”。故答案为A。
