A Phone That Knows You're Busy

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 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.

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.

资料：Because of the biochemical reactions in your body that occur with every type of food you eat on a daily bases, some foods age you faster than your real age, while other foods help to fight aging.
Three of the processes that go on inside your body that have a major impact on your rate of aging are called “glycation”, “inflammation” and “oxidation”.
When we talk about aging, we’re not just talking about wrinkles on your skin or how thick your hair is, we’re also talking about factors that you can’t see, such as how well your organs function, and whether your joints are degrading.

According to the passage, aging is about all the following except--.

A.the degrading joints
B.the thinning of your hair
C.the good condition of your organs
D.the wrinkles around your eyes

资料：Procrastination comes in many disguises. We might resolve to tackle a task, but find endless reasons to defer it. We might prioritize things we can readily tick off our to-do list- answering emails, say- while leaving the big, complex stuff untouched for another day. We can look and feel busy. while artfully avoiding the tanks that really matter. And when we look at those rolling, long untouched items at the bottom of our to-do list, we can't help but feel a little disappointed in ourselves.
The problem is our brains are programmed to procrastinate. In general, we all tend to struggle with task that promise future upside in return for efforts we take now. That's because it's easier for our brains to process concrete rather than abstract things, and the immediate hassle is very tangible compared with those unknowable, uncertain future benefits. So the short-term effort easily dominates the long-term upside in our minds--an example of something that behavioral scientists call present bias.
How can you become less myopic about your elusive tasks? It's all about rebalancing the cost benefit analysis: make the benefits of action feel bigger, and the costs of action feel smaller. The reward for doing a pestering task needs to feel larger than the immediate pain of tacking it.
To make the benefits of action feel bigger and more real:
Visualize how great it will be to get it done. Researchers have discovered that people are more likely to save for their future retirement if they're shown digitally aged photographs of themselves. Why? Because it makes their future self feel more real-making the future benefits of saving also feel more weighty.

Which one is TRUE about our brain?

A.Concrete things are more attractive than the abstract things.
B.The long term upside is easily dominated by short-term effort in our minds.
C.We cannot avoid present bias in our brain.
D.The brain can be trained to procrastinate often.

Looking to help the environment?Consider the following simple ideas.
Turn off electrical devices when they're not being used.
Turning off,rather than leaving on stand-by,things like your TV and computer will save huge amounts of energy. With this,we can all help reduce the amount of carbon dioxide emitted into the earth's atmosphere,thereby reducing pollution and global warming.
Share your car.
Rather than traveling to work alone,why not arrange car-sharing with one or more of your friends or colleagues?To give you an example,if you drive a fashionable car,you will use more energy in a year than you would leaving your fridge open for seven years,or your TV on for thirty-two years!Imagine the savings if you shared your car with 2,3 or even 4 other people!
Refuse junk mail.
While we all complain about how much junk mail we get,we very rarely do anything about it. The mail continues to go straight from our letter-boxes into the garbage bin-with 99% of it not even opened.What can you do about this?There are various websites where you can register to receive no junk mail.As well as saving time,you'll also be doing a lot for the environment. Each year,100 million trees are used to produce junk mail. 250,000 homes could be heated with one day's supply of junk mail.
There are many other everyday changes you can make to help the environment. They will cost you nothing,and many will actually save you money!Why not give it a try?We can all help, if we really want to.

The only drawback of junk mail is that it wastes out time.
A: Right

Things We Know about TV

We keep reading that TV is bad for you.If this is true,how come the current generation of TV-addicted kids is much smarter than we are?In my home,the only people who can work the remote control are the children.
Perhaps TV does educate you.For example,you learn a useful medical fact:A person who has been shot always has time to speak an incomplete sentence before he dies.“The killer was…” (dies).
But I guess the biggest things we learn from TV can be regarded as"Life Skills".Bad things only happen on dark and stormy nights.Emotional breakdowns cause people to wander in the heavy rain without umbrellas.And contrary to what scientists say,the crack（霹雳）of lightning and the accompanying flash happen at exactly the same time,wherever you are.
Making use of what we learn from TV can improve our security.Consider these truths.If you are ever attacked by 20 bad guys,don't worry about being outnumbered.The criminals will hang back and take turns to approach you in ones and twos just so you can conveniently defeat them all.
TV also teaches us important information about escaping from danger. Watch and learn.If anyone is running after you down a passage,you will find that boxes have been conveniently placed near all the walls you need to jump over. If you are tall and handsome,you can run from any number of armed criminals,and every shot will miss you.
Be warned, however. If your name card says "henchman"（帮凶）and you are part of a group of plain-looking people trying' to catch a handsome individual,a single shot will kill you.
TV even teaches us about TV.Whenever anyone turns on a TV,it shows a news flash about someone they know. They then turn the box off immediately after that news item.

We can learn from Paragraph 3 that in the real world__________.
A:bad things cause people to break down in the rain
B:bad things never happen on dark and stormy nights
C:people with emotional problems like to walk in the rain without umbrellas
D:the crack of lightning and the flash don't harmen at the same time
