More Than a Ride to School
The National Education Association claims. " The school bus is a mirror of thecommunity. " They further add that, unfortunately, what appears on the exterior does not alwaysreflect the reality of a chosen community. They are fight -- sometimes it reflects more! Just askLiesl Denson. Riding the school bus has been more than a ride to school for Liesl.
Bruce Hardy, school bus driver for Althouse BUS Company has been Liesl's bus driversince kindergarten. Last year when Liesl's family moved to Parkesburg, knowing her bus wentby her new residence. She requested to ride the same bus.
This year Liesl is a senior and will enjoy her last year riding the bus. She says, " It's beena great ride so far! My bus driver is so cool and has always been a good friend and a goodlistener. Sometimes when you're a child adults do not think that what you have to say isimportant. Mr. Hardy always listens to what you have to say and makes you feel important. "Her friends Ashley Bafista and Amanda Wolfe agree.
Bruce Hardy has been making Octorara students feel special since 1975. This year he willcelebrate 30 years working for Althouse Bus Company, Larry Althouse, president of thecompany, acknowledges Bruce Hardy's outstanding record: "You do not come by employeeslike Bruce these days. He has never missed a day of work and has a perfect driving record. Hewas recognized in 2000 by the Pennsylvania School Bus Association for driving 350,000accident free miles. Hardy's reputation is made further evident through the relationships he hasmade with the students that ride his bus. "
Althouse further adds, "Althouse Bus Company was established 70 years ago and has beenproviding quality transportation ever since. My grandfather started the business with one bus.Althouse Bus Company is delighted to have the opportunity to bring distinctive and safe serviceto our local school and community and looks forward to continuing to provide quality service formany more years to come. "
hree generations of business is not all the company has enjoyed. Thanks to drivers likeBruce Hardy, they have been building relationships through generations, Liesl's mother Carolalso enjoys fond memories of riding Bruce Hardy's bus to the Octorara School District.

A Phone That Knows You're Busy
It's a modem problem: you're too busy to be disturbed by incessant (连续不断的) phonecalls so you turn your cell phone off. But if you don't remember to turn it back on when you'reless busy. You could miss some important calls if only the phone knew when it was wise tointerrupt you, you wouldn't have to tum it off at all. InsteaD. it could let calls through whenyou 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 aphone, the system may decide you're too busy and ask the caller to leave a message or ring backlater.
James Fogarty and Scott Hudson at Carnegie Mellon University in Pennsylvania based theirsystem 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 strongly predict whether yourmind is interrupted.
The potential "busyness" signals they focused on included whether the office doors wereleft open or closeD. the time of day, if other people were with the person in question, howclose 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. Atrandom intervals, the subjects rated how interrupdble they were on a scale ranging from "highlyinterruptible" to "highly not-interruptible". Their ratings were then correlated with the variousbehaviors . "It is a shotgun (随意的) approach: we used all the indicators we could think ofand 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 toobusy 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 biasedtowards delivering their message, whereas computers don't care.
The first application for Hudson and Fogarty's system is likely to be in an instant messagingsystem, 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 that
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 cell phone
D.they are too busy to make phone calls
37、 The behavior sensor and software system built in a phone
A.could help store messages
B.could send messages instantly
C.could tell when it is wise to interrupt you
D.could identify important phone calls
38、 Scientists at Carnegie Menon University tried to find out
A.why office doors were often left open
B.when it was a good time to turn off the computer
C.what questions office workers were bothered with
D.which behaviors could tell whether a person was busy
39、 During the experiment, the subjects were asked
A.to control the sensors and the camera
B.to rate the degrees to which they could be interrupted
C.to compare their behaviors with others'
D.to analyze all the indicators of interruption
40、 The computer performed better than people in the study because
A.the computer worked harder
B.the computer was not busy
C.people tended to be biased
D.people were not good at statistics

The Exploding Lakes of Cameroon
What comes to mind when you think of a lake? You probably imagine a pretty scene withblue water, birds, and fish. For the people in the northwestern Cameroon, however, the image is very different. For them, lakes may mean terrible disasters. In 1984, poisonous gasesexploded out of Lake Monoun and came down into the nearby villages, killing thirty-sevenpeople. Two years later, Lake Nyos erupted. A cloud of gases rolled down the hills and into thevalleys and killed 1,700 people.
Lake Nyos and Lake Monoun are crater (火山口) lakes They were formed when watercollected in the craters of old volcanoes. The volcanoes under Lake Nyos and Lake Monoun arenot active anymore. However, poisonous gases from the center of the earth continue to flow upthrough cracks in the bottom of the lake. This is normal in a crater lake. In most crater lakes,these gases are released often because the water "turns over" regularly. That is, the water fromthe bottom of the lake rises and mixes with the water at the top, allowing the gases to escapeslowly.
However, in Lakes Nyos and Monoun, there is no regular turning over. No one knows thereason for this fact, but as a result, these lakes have more gases tapped at the bottom than othercrater lakes. In fact, scientists who have studied Lakes Nyos and Monoun have found 16,000times more gases. When a strong winD. cool weather a storm, or a landslide (滑坡) causesthe water to turn over suddenly, the gases escape in a violent explosion.
In the past, no one knew when the gases might explode, so there was no way for thevillagers to escape disaster. Now scientists from the United States, France, and Cameroon havefound a way to reduce the gas pressure at the bottom of Lake Nyos. They stood a 672-footplastic pipe in the middle of the lake, with one end of the pipe near the bottom and the otherend in the air. Near the top of the pipe, the team putseveral holes that could be opened orclosed by a computer. Now, when the gas pressure gets too high, the holes are opened andsome of the gas-filled water shoots up through the pipe into the air like a fountain. With lesspressure, a disastrous explosion is much less likely. However, the scientists are not sure thatone pipe will be enough to prevent explosions. They hope to put in others soon and they plan toinstall a similar pipe and a computer system at Lake Monoun as well.
To protect people nearby until all of the pipes are in place, the scientists have installedearly warning systems at both lakes. If the gas pressure rises to a dangerous level, computerswill set off loud sirens (劲爆) and bright lights to warn the people in the villages. That way,they will have time to escape from the dangerous gases.
