共享题干题根据下列材料，回答题 A Phone That Knows You're Busy It's a modem problem: you're too busy to be disturbed by incessant (连续不断的) phone calls so you turn your cell phone off．But if you don't remember to turn it back on when you're less busy. You could miss some important calls if only the phone knew when it was wise to interrupt you, you wouldn't have to turn it off at all. Instead, it could let calls through when you are not too busy. A bunch of behavior sensors (传感器) and a clever piece of software could do just that, by analyzing your behavior to determine if it's a good time to interrupt you. If built into a phone, the system may decide you're too busy and ask the caller to leave a message or ring back later. James Fogarty and Scott Hudson at Camegie Mellon University in Pennsylvania based their system oil tiny microphones, cameras and touch sensors that reveal body language and activity. First they had to study different behaviors to find out which ones strongly predict whether your mind is interrupted.The potential "busyness" signals they focused on included whether the office doors were left open or closed, the time of day, if other people were with the person in question, how close they were to each other, and whether or not the computer was in use. The sensors monitored these and many other factors while four subjects were at work. At random intervals, the subjects rated how interruptible they were on a scale ranging from "highly interruptible" to "highly not-interruptible". Their ratings were then correlated with the various behaviors . "It is a shotgun (随意的) approach: we used all the indicators we could think of and then let statistics find out which were important, " says Hudson. The model showed that using the keyboard, and talking on a landline or to someone else in the office correlated most strongly with how interruptible the subjects judged themselves to be. Interestingly, the computer was actually better than people at predicting when someone was too busy to be interrupted. The computer got it right 82 per cent of the time, humans 77 per cent. Fogarty speculates that this might be because people doing the interrupting are inevitably biased towards delivering their message, whereas computers don't care. The first application for Hudson and Fogarty's system is likely to be in an instant messaging system, followed by office phones and cellphones. "There is no technological roadblock (障碍) to it being deployed in a couple of years, " says Hudson.1.[不定向选择题]During the experiment, the subjects were asked________.A.to control the sensors and the camera B.to rate the degrees to which they could be interrupted C.to compare their behaviors with others' D.to analyze all the indicators of interruption 2.[不定向选择题]The behavior sensor and software system built in a phone________.A.could help store message B.could send messages instantly C.could tell when it is wise to interrupt you D.could identify important phone call

1.参考答案：B
参考解析：实验中，受试者被要求干什么?A、控制传感器和照相机。?B、评定哪种情况他们能够被打断。C、将其行为与其他人进行对比。D、分析所有中断的指标。?细节题。利用题干关键词subject可以定位文中第五段第二句“the subjects rated how interruptible they were on a scale ranging from“highly interruptible”to“highly not—interruptible”，意为“受试者对是否可被打断工作做出评定，评定范围从‘完全可以被打断’到‘完全不能被打断”’。所以选项B为正确答案。?
2.参考答案：C
参考解析：行为传感器和软件系统内置在手机中。?A、能够帮助存储消息B、能够立即发送消息C、能够智能地告知什么时候打扰你?D、能够识别重要电话?细节题。根据题干关键词behavior sensors和software可以定位到第二段中第一句“A bunch of behavior sensors(传感器)and a clever piece of software could do just that，”其中that是代词，指上段最后两个句子的内容。而答案在第一句的后半部分“it could let calls through when you are not too busy”意为“确定何时适合打扰你”，故选项C为正确答案。?3.[不定向选择题]The computer performed better than people in the study because________.A.the computer worked harder? B.the computer was not busy C.people tended to be biased? D.people were not good at statistic

这个解释是对的
