1． What is the modern conundrum the author has in mind?
A．You turn off your cellophane but forget to turn it back and miss important calls
B．You are too busy to make phone calls and miss important information
C．Too many calls are annoying, affecting your work efficiency
D．Too many calls are disturbing, producing serious noise pollution
1． A。分析：利用题干中的modern conundrum作为答案线索，这样发现答案相关句：It’s a modern conundrum(难题): you’re too busy to be disturbed by incessant phone calls so you turn your cellophane off． But if you don’t remember to turn it back on when you’re less busy, you could miss some important calls． （该句大意说“在不忙的时候因为忘了开机而错过重要的电话”）因此判断A是答案。

2． According to paragraph 2, what could a bunch of behavior sensors and a clever piece of software do?
A．they could help store messages
B．they could distinguish important calls from unimportant ones
C．they could interrupt you when you are not busy来源：考试大
D．they could send messages instantly
2．C．分析：利用题干中的behavior sensors 和 clever software作为答案线索，这样发现答案相关句：(第2段)A bunch of behavior sensors 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．） 借助划线句子的大意“智能软件和行动感应器能通过分析你的行为来确定是否应该打断你”判断C是答案。考题考察代词的指代内容：that 指代前面句子的内容：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 during spells （一段时间）of relative inactivity（不活跃）． 这两个句子也是说“通过智能技术判断是否可以打断你”，因此也判断C是答案。

3． Which of the following is not included in paragraph 3 as a potential “busyness”signal?
A．whether the office door is open or not．来源：考试大
B．Whether there are people with the person in question or not
C．Whether the person is using the computer or not
D．Whether the person is bothered by a question or not．
3 D。用题干中的特征短语“busyness”signal作为答案线索，这样发现答案相关句：The potential “busyness”signals they focus on included whether the office doors were left open or closed(与A一致), the time of day, if other people were with the person in question（与B一致）, how close they were to each other, and whether or not the computer was in use（与C一致）．因此只有D没有被提到。

4． According to paragraph 4, what were the subjects required to do during the experiment?
A．to control the sensors and many other factors
B．to rate the degrees to which they could be interrupted
C．to read and analyze all the indicators来源：考试大
D．to decide which indicators were important statistics
4．B．分析：利用题干中的subjects（研究对象）作为答案线索，这样发现答案相关句：（第4段）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”． (该划线句内容与B一致：对是否能被打断工作作出评定)

5． Which of the following is not mentioned as strongly correlated with how interruptible they were?
A．working at the computer来源：考试大
B．talking over the telephone
C．repairing the keyboard
D．talking with people in the office来源：考试大
5． C。分析：问题句问“在决定“‘是否能够被打断’的因素中，下面哪项在文章中没有被提到”，顺着上一题的答案位置往下找，这样发现了答案相关句：The model showed that using the keyboard, and talking on a landline（通讯电缆） (与A和B呼应)or to someone else in the office （与D呼应）correlated most strongly with how interruptible the subjects judged themselves to be． 因此判断C是答案。
