A new term has begun. Teachers are 41 about the fact that new students are not easy to deal with. They like to bring cell phones and MP3 players to school. What is worse , some students even use cell phones 42 out-of-class matters in class, or sometimes just for fun. Some 43 students listen to MP3 players when they are having a lesson that they are not interested in. Are these new students really that 44 ? “Yes.” Says Delaney Kirk, a professor（教授） at Drake University. But she adds it’s not their fault. 45 , the teachers should be blamed(责备). Mrs Kirk first began thinking about students’ manners six years ago. “I had my first class in which students were sleeping or talking to each other. It seemed that learning well had nothing to do with them.” She says. “At first, I got worried about this.” But then I said to 46 , “You’re giving lessons, and you need to manage this kind of situation. These students need to know more about manners. It’s time to help them develop some good 47 . They shouldn’t waste time doing nothing when they are young. Sooner or later, they may regret(后悔) the time they 48 .” Mrs Kirk also makes a list of suggestions to help teachers better manage（驾驭） their classes. The following are among her suggestions: On the first day of class, tell students how they will benefit(受益)by taking the class and the importance 49 listening carefully in class. Do not allow them to bring cellphones or MP3 players to the class at all. Tell them 50 to use cell phones or MP3 players properly(适当地)..

规划师老许制定的网络系统测试计划中，链路速率测试方案是：对核心层的骨干链路和汇聚层至核心层的上连链路，应进行全部测试；对接入层到汇聚层的上连链路，以不低于10%的比例进行抽样测试(若链路数不足10条时，则全部测试)。网络传输时延测试方案是：将测试设备以环回方式连接到有正常业务流量的被测网络中，若系统在1518字节帧长情况下，从两个方向测得的10次传输时延的平均值不超过1ms，则判定为合格。
对链路速率测试方案的评价，恰当的是___70___，对网络传输时延测试方案的评价，恰当的是___71___。
71（）
A．是一个标准的测试方案
B．测试设备发送的数据帧帧长应改为64字节
C．从两个方向测得的10次传输时延的平均值应不超过0.5ms
D．测试必须在空载网络下分段进行且必须测试20次
