( 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。

圈出来的部分，说是用that不用which，但是没明白为什么

曼哈顿里的例句 A hard worker and loyal team player, the new project was managed by Sue. 书上说的是前面的modifier会错误修饰project,但平时阅读的时候读到这个是能够判断这个修饰语是不会用来修饰project的，会对阅读产生阻碍但不会令人误解。因此想问Gmat语法中这种例子是绝对不对还是不优呢。

还请MAY老师帮忙解答下这道题，我选的B，没弄明白，谢谢

请问数学老师 为什么这个题不是0.8*0.4+0.2*0.6。因为两个不同时发生啊

请问数学老师 这个题为什么不能直接是九分之二

请数学老师解答。这个题您没答完吗？这是系统出问题了吗？

请数学老师解答条件2为什么可以

请数学老师讲解 条件1为什么可行 谢谢

请数学老师讲解思路 谢谢

请数学老师讲下思路，这个题我始终都无法算出正确结果
