( Monitoring heart patients' exercise as well as athletes excersing, is now done by small transmitters broadcasting physiological measurements to nearby recording machines. ) A. Monitoring heart patients' exercise as well as athletes excersing, is now done by small transmitters broadcasting physiological measurements to nearby recording machines. B. Monitoring the exercise of heart patients, as well as athletes excersing, is now done by small transmitters broadcasting physiological measurements to nearby recording machines. C. Small transmitters broadcasting physiological measurement to nearby recording machines are now used to monitor the exercise of both heart patients and athletes. D. Broadcasting physiological measurements to nearby recording machines, small transmitters are now used to monitor heart patients' exercise, as well as athletes exercising. E. Both athletes exercising and heart patients' exercise are now monitored by small transmitters broadcasting physiological measurements to nearby recording machines. 答案是C，错选了E。排除C的原因是感觉主语很长，头重脚轻。第一遍看原文的时候感觉exercise和exercising不平行，但是每个选项读下来发现都是这个形式，（当时没有注意到C的形式）于是就认为这个可能不是考点。E的错误是exercise和exercising吗？麻烦老师讲解。

请小郭老师帮我归纳 谢谢

想问一下金老师，在句子最后的逗号后面的ing形式的非谓语动词的主语是不是可以是主句的主语，也可以是整个主句，还可以是离它最近的一套完整主谓宾的主语？那碰到题目是要三种情况都考虑一下吗？还有如果是逗号加ing形式的非谓语动词在句子中间的话，是修饰前面还是后面呢，主语又是谁呢？
