( 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。

这道题感觉A也好对

感觉C对因为可以降低运输成本

请翻译下however后这句话的意思

老师请教这个中文的题 答案是D，但我选的B，我认为条件1是不能判断出来的 第二张图片是当时老师上课讲的，请问蓝色的0.1a是怎么得出来的啊

老师，这个变体条件得出来的不是整除的式子，为啥能满足题干条件？谢谢

老师，这道题有点困惑，题目问的是最大公约数是多少，为什么直接选B，最大公约数是1？

这个题ACDE都错在哪里了呢？为什么选B呀

这题以前上学时就没见过，老师可帮忙讲下逻辑和原理么？

老师，这里的+63看不太懂，谢谢

请问这题里说一个化学反应等于一个数的平方，同时又等于另一个数的倒数，那这样，这个平方和这个倒数应该是相等的关系，为什么是一个相乘的关系然后再等于R呢？
