( 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。

请问这道题C选项and前后为什么可以是并列关系？

为什么选A？and之后的instead come是跟will avoid 并列嘛？还有就是 SVO+doing的形式到底能不能用？怎么用？

请问老师 画线部分这句话怎么没有谓语呢？我想了很久是省略了have been? 如果是这样的话，我发现省略的情况会影响我的阅读，可能是我对英文省略这块的语法不熟悉（什么时候可以省略，哪些可以省略等）老师能发我一些关于省略语法的资料我读读嘛，谢谢

从句不知道修饰谁的问题，有就近修饰的说法吗？怎么判断修饰谁呢：第一句 状语从句Where……打括号部分修饰museum还是Italy，说修饰Italy好像也翻译的通；第二句 that引导的从句 打括号部分修饰rationale还是social and political realities？在句中作什么成分呢; 第三句 that从句修饰evidence还是前面的Middle East？从句中的with和but怎么连在一起用呢

求问这个题，麻烦老师简明扼要解答一下 谢谢～

请问老师 如果是the Audubon society and other conversation groups发出的动作，为什么是concerned 不是concerning？画线部分是在句中是什么成分呢
