It’s a modern problem: You’re too busy to be disturbed by incessant (连续不断的) phone calls so you turn your cellphone 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 on tin A. they must tolerate phone disturbances or miss important calls. B. they must turn off their phones to keep their homes quiet. C. they have to switch from a desktop phone to a cellphone. D. they are too busy to make phone calls. [单项选择]肺动脉高压早期的X线表现是().
