理工類A級：閱讀理解A Phone That Knows
Its a modern problem：youre too busy to be disturbed by incessant(連續不斷的)phone calls so you turn your cellphone off .But if you dont remember to turn it back on when youre less busy.you could miss some important calls if only the phone knew when it was wise to interrupt you，you wouldnt have to turn it off at all. Instead，it could let calls through when you are not too busy
A bunch of behavior sensors(傳感器)and a clever piece of software could do just that，by analyzing your behavior to determine if its a good time to interrupt you.If built into a phone，the system may decide youre 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 stongly 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 interruptibleto"highly not-interruptible" . Their ratings were then correlated with the various behaviors . "It is a shotgun(隨意的)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 dont care.
The first application for Hudson and Fogartys system is likely to be in an instant messaging system，followed by office phones and cellphones."There is no technological roadblock(障礙) to it being deployed in a couple of years，" says Hudson
36 A big problem facing people today is that

參考答案：
36 A 該題問的是：當今人們面臨的一個大的問題是什么?文章第～句就給出了答案：人們太忙了，不能被連續不斷的電話騷擾。要么關閉手機。
37 c 第二段中的that是代詞，指上段最后兩旬句子的內容。而答案在第一句的后半部分：確定何時適合打擾你。
38 D 本題題干的意思是在Camegie Mellon大學的科學家試圖找出……?答案在第三段最后一句，第四段第一句也給出了部分答案。
39 B 本題問的是實驗中，受試者被要求干什么?答案在第五段第二句：受試者對是否可被打斷工作做出評定，評定范圍從"完全可以被打斷"到"完全不能被打斷".
40 c 本題和倒數第二段第一句有關，說的是實驗中電腦比人表現得好，問原因是什么?這段最后一句說了，people doing the interrupting are inevitably biased…，即人有偏見，故c為答案。
