A Phone That Knows Youre Busy
A bunch of behavior sensorsand 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.
The potentialbusynesssignals 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 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.
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 to it being deployed in a couple of years， says Hudson
A they must tolerate phone disturbances or miss important calls.

36 A 该题问的是：当今人们面临的一个大的问题是什么?文章第～句就给出了答案：人们太忙了，不能被连续不断的电话骚扰。要么关闭手机。
38 D 本题题干的意思是在Camegie Mellon大学的科学家试图找出?答案在第三段最后一句，第四段第一句也给出了部分答案。
40 c 本题和倒数第二段第一句有关，说的是实验中电脑比人表现得好，问原因是什么?这段最后一句说了，people doing the interrupting are inevitably biased，即人有偏见，故c为答案。
