Feelings aren't usually associated with inanimate machines, but Rosalind Picard, a professor of computer technology at MIT, believes emotion may be just the thing computers need to work effectively. Computers need artificial emotion to understand their human users better and to achieve self-analysis and self-improvement.
The more scientists study the "wetware" model for computing—the human brain and nervous system—the more they conclude that emotions are a part of intelligence, not separate from it. Emotions are among the tools that we use to process the tremendous amount of stimuli in our environment. They also pay a role in human learning and decision making. Feeling bad about a wrong decision, for instance, focuses attention on avoiding future error. A feeling of pleasure, on the other hand, positively reinforces an experience.
"If we want computers to be genuinely intelligent, to adapt to us, and to interact naturally with us, then they will need the ability to recognize and express emotions, to have emotions, and to have what has come to be called 'emotional intelligence,'" Picard says.
One way that emotions can help computers, she suggests, is by helping keep them from crashing. Today's computers produce error messages, but they do not have a "gut feeling" of knowing when something is wrong or doesn't make sense. A healthy fear of death could motivate a computer to stop trouble as soon as it starts. On the other hand, self-preservation would need to be subordinate to service to humans. It was fear of its own death that prompted HAL, the fictional computer in the film 2002: A Space Odyssey, to kill most of its human associates.
Similarly, computers that could "read" their users would accumulate a store of highly personal information about us—not just what we said and did, but what we likely thought and felt.
"Emotions not only contribute to a richer quality of interaction, but they directly impact a person's ability to interact in an intelligent way," Picard says. "Emotional skills, especially the ability to recognize and express emotions, are essential for natural communication with humans."
In the future computers will tend to be made ______.
A．fictional
B．humanized
C．economical
D．operational
e control. It seems a dream in the future. It isn't.
In many ways such driverless cars are already with us. There is partial automation in many cars, such as intelligent braking, lane departure warning and automatic parking. The systems are there {A; B; C} cars can pretty much drive themselves. No one noticed the introduction of cruise control. We've got collision avoidance, and we'll soon have automatic lane change.
Improving this technology should make the roads safer. Machines are much better at following rules than humans. Driveway signs advise drivers to slow down to avoid {A; B; C} jams. They are often ignored by drivers. But it won't happen {A; B; C} a computer. Driverless cars could also choose the best route to avoid traffic jams.
Fewer jams will mean {A; B; C} stop-start driving. Maintaining smooth and constant speeds will improve fuel efficiency. Computers could also be programmed to take the greenest route, rather than the fastest one. Under computer control, cars could also travel much closer together.
They can effectively “slipstream” one another and use less fuel to move themselves forward. They can even form. multi-car “trains” going {A; B; C} high speeds. However, with driverless cars on the roads, there will be potential trust issues between people and machines. We could therefore see guard rails back on the sides of pavements. This would be a backwards step.

People in the US can now carry an artificial intelligence (AI) around in their pocket, where it waits patiently to be told what to do.
Siri, an iPhone application that understands spoken commands and uses the web to carry them out,is a byproduct from a US military project to develop an artificially intelligent assistant.
Many people's experience of a "virtual assistant" may be limited to Microsoft's annoying classic Mr. Clippy. But in the week we spent together, my AI assistant has performed admirably in finding me restaurants, or the location of the nearest coffee shop. It wasn't even stumped when I asked "do I need my umbrella today？" coming straight back with the local weather forecast.
A typical command might be: "Reserve a table for two at a good French restaurant in San Francisco." Siri responds by presenting a list of top-rated restaurants that can be booked on OpenTable.com. If you say which time you want, it can book you a table without your lifting a finger.
In some ways Siri is just a fancy front-end to the 35 sites it can connect to, from taxi booking sites to movie review databases. But what's new is the way it can interpret the intentions of its master or mistress and use those sites to put them into action.
Doing that requires the ability to actually understand the meaning of words you use, not just passing on keywords blindly, says Siri co-founder Adam Cheyer.
"Book a four-star restaurant in Boston seems pretty straightforward," says Cheyer, "until you realise that Book is a city in the US, and Star is also a city in the US, and there are 13 Bostons, and Star is also the name of a restaurant."
To cut through what Cheyer calls the "combined explosion of interpretations", Siri uses your location, and the history of the commands you've given. It knows that "book" is most likely a command verb, unless you happen to be near the city of Book.
Siri attaches probabilities to the interpretation of each word and cross-reference(参照) with your location and other data, some of which you must provide yourself.
According to the passage, Siri is most probably ______.
A．still at its experimental stage
B．very popular with iPhone users
C．a US military assistant software
D．an artificial intelligence software
He ______ reading silently at first.
A．used not to
B．didn' t use to
