If you don’t have much experience of making phone calls in English, making a business call can be a worrying experience. Most business people, unless they feel very confident, prepare for an important phone call in a foreign language by making notes in advance. And during the call they make notes while they’re talking to help them to remember what was said. Although it’s quick and convenient to phone someone to give them information or to ask questions, the disadvantage is that there is nothing in writing to help you to remember what was said. It’s essential to make notes and often when an agreement is reached on the phone, one of the speakers will send a fax or e-mail to confirm the main points that were made. Because it’s so easy to be misunderstood when talking on the phone, it’s a good idea to repeat any important information (especially numbers and names) back to the other person to make sure you’ve got it right. Always make sure you know the name of the person you’re talking to. If necessary, ask them to spell it out to you, so that you can make sure you’ve got it right----and try to use their name during the call. And make sure that they know your name too.1. If you don’t have much experience of making phone calls in English, making a business call can be ().A.an easy thingB.a happy experienceC.a painful thing2.Most business people prepare for an important phone call in a foreign language by making notes in advance because ().A.they are very carefulB.their foreign language isn’t so goodC.they don’t want to miss any important information3. When the speakers reach an agreement on the phone, ()will send a fax or e-mail in order to confirm the main points that were made.A.one of themB.both of themC.none of them4.What does “IT” refer to in the first sentence in_Paragraph Four_----“…it’s a good idea to repeat any important information (especially numbers and names) back to the other person to make sure you’ve gotITright”()A.important informationB.the other personC.a good idea5.The best title of this passage is().A.The Importance of Taking NotesB.Business CallsC.Talking on the Phone

第二篇A Phone That Knows You're BusyIt'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 onwhen 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 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 percent of the time,humans 77 percent.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.A big problem facing people today is thatA: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.
