Smart phones that react to your moods and televisions that can tell it’s you who’s watching are in your future as Intel Corporation’s top technology expert sets his sights on context-aware computing.

Chief technology officer Justin Rattner showed how personal devices will one day offer advice. “How can we change the relationship so we think of these devices not as devices but as assistants or even companions?” he asked.

Handheld devices could combine already common geographic location technology with data from microphones, cameras, heart and body monitors and even brain scans to offer their owners advice that today only a friend or relative could give.

“Imagine a device that uses a variety of sensors to determine what you are doing at an instant, from being asleep in your bed to being out for a run with a friend, ” Rattner said, “Future devices will constantly learn about who you are, how you live, work and play.’’

Rattner also demonstrated a television remote control that figures out who is holding it based on how it is held, and then learns the viewer’s entertainment preferences.

As the world leader for decades in microchips for servers and desktop computers, Intel is hurrying to catch up in the profitable market for smart phones like Apple’s iPhone and Research in Motion’s Blackberry.

Telephones with e-mail, global positioning and media players are pointing the way to a future where ever more functions are packed into ever smaller mobile devices.

The smart phone industry, including technology giants like LG and Samsung, is likely to sell 270 million phones this year and grow 25 percent in 2011, according to market research company IDC.

“I think you can expect to see features that support context-aware computing starting to appear in Intel products in the near future,” Rattner said.

But analysts say Intel faces an uphill battle getting its microchips into new phones as Nvidia, Marvell and Qualcomm have already made headway with cheap, lower-power processors based on designs by ARM Holdings.

Rattner recognized that questions about privacy and people’s willingness to be intimate with their computers will have to be settled before the future generation of smart phones he described takes off.

“If you think identity threat is a problem today, imagine when your whole context is readily available on the Net.”, he said.

1.The future smart phones can do all of the following except _______.

2.Which of the following are smart phones according to the passage?

3.From the passage we can infer that _______.

4.The best title for the passage is likely to be _______.

When I was a boy there were no smart phones, and our television only got one channel clearly. Still, I never felt bored. The fields, hills and woodlands around my home were the perfect playground whose adventures were only limited by my imagination. I can remeber once hiking to nearby lake and walking slowly around it. At the back of it I was amazed to find an old dirt road that I had never seen before. It was full of muddy tyre tracks and deep woods bordered it on both sides, but exploring it still seemed like a fine adventure.

I walked on and on for what seemed like hours. I was sure my guardian angel was whispering in my ears “turn around and head back home”, but I was stubborn and walked on. There was still neither a car nor a house in sight. I noticed that the sun was starting to go and down I grew scared. I didn’t want to end up trapped on this road, and I was worried that it would be dark before I could make my way back to the lake again.

I continued to walk on with something growing inside of me. My heart was pounding and my legs were aching. I was almost in tear s when I saw something in the distance. It was a house that I recognized. I jumped up and down and laughed out loud. It was still over a mile away, but my legs felt like feathers and I hurried back to my house in no time. I walked in with a big smile on my face just in time for dinner. Then I ended my adventure with a good night’s sleep.

I often thought of that experience recently. Actually, in our life, all roads, no matter how they twist and turn, can lead us home again. They can lead us to hey can lead us to our homes in our hearts. May you always walk your path with love! May you always help you r fellow travelers along the way!

In the near future, we may be using our eyes to operate our smart-phones and tablets, even when it comes to playing popular games like Fruit Ninja.

The Gaze Group has been developing eye-controlled computer technology for nearly 20 years. But those devices have been firstly designed to help those with disabilities, and are very expensive.

“After a while, we figured out that probably the best way is to go for a mass-market way,” says Gaze’s Sune Alstrup Johansen. “where everybody would have this available.”

Johansen and some of his colleagues have formed a new company, the Eye Tribe, which is hoping to develop the technology on a mass commercial level.

The technology works when combined with the computing device toward the user’s face. After making sure of the user’s eye movements, the technology is then able to easily find where a person’s eyes are moving, and then allow the eyes to control a cursor (光标).

“Our software can then determine the location of the eyes and know where you’re looking on the screen to make sure what you’re looking at,” reads an explanation on the Eye Tribe site.

There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world. Recently Xbox released the Kinect device, which lets users control their Xbox and play certain games using only their hands, legs and voices. But sill, most of these devices have been more of a gimmick than a practical way to use one’s hands to control a mobile device. Johansen said a replaceable filter (滤光器) would be a cheap, convenient way for most consumers.

And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.

Studies have documented that smiling is a universal and effective way to lift mood. But in the latest research on the power of the smile, researchers led by Marcus Munafo of the University of Bristol in England found that even seeing smiles on the faces of others can have a profound effect on a person's tendency toward violence or aggression — that is, as long as that person recognizes the smile as one of happiness, and not as a sneer (讥笑)．

Munafo and his colleagues conducted a series of experiments involving normal adults and highly aggressive teens referred to a youth program, either by educational authorities or the courts. About 70% of the teens already had a criminal record.

In the first experiment, 40 healthy adults, aged 18­30, looked at facial expressions on the computer ranging from happy to angry with increasingly difficult ones to discern in between. Participants were asked how angry they felt and then had to rate the images as displaying either happiness or anger — there was no option for “unclear” or “unable to tell”. From these ratings, the scientists could generate a score of their preference toward happiness or anger.

Previous research found that aggressive people — including violent offenders — tend to consider even a common expression as an unfriendly one. “You looking at me？” can easily turn a simple question into a tragic fight.

Based on their original scores, half of the participants were then told by the computer that some of the unclear faces that they had rated as angry should have been scored as happy. This was intended to guide them toward judging the in­between faces more positively. The other 20 received feedback that simply proved their first choices, creating a control group.

After this training, both groups were tested again and the group that received the biased (有偏见的) feedback shifted its ratings of unclear faces toward the happy side. Participants were also asked to rate their level of angry feelings again after completing the second round of testing. Those who were trained to consider unclear faces as happier reported feeling less angry afterward.

The researchers next focused on the 46 adolescents from the high risk youth program. These teens completed the same testing, but both the youth and the staff reported on the teens' levels of aggressive behavior before the testing started and for two weeks afterward. The teens trained to interpret unclear facial expressions more positively were significantly less aggressive two weeks later.

“The results of our experiments strongly suggest that the understanding of emotional facial expressions plays a causal role in subjective anger and aggressive behavior，”the authors conclude.

That doesn't mean that smiles alone are the answer to violence among adolescents — previous research in which anti­social youth were trained to better recognize emotions, for example, did not have any effect on their level of aggressive behavior. But this earlier study focused on improving teens' understanding of clear facial signals, not unclear ones. Since unclear signals are more likely to be misunderstood, it may be that violent behavior in some youth exists with their constant misunderstanding of angry expressions where they don't exist, which push them to aggressive responses. The findings suggest that helping young people, particularly those easy to be violent, to learn to give others the benefit of the doubt when they see what they think is a threatening face could help end the vicious (恶性的) cycle of violence.

1.The underlined word “discern” (Paragraph 3) means ________.

A．display obviously　 B．identify clearly

C．describe correctly　 D．value properly

2.According to Munafo's research, the anger and violent behavior in some youths resulted from ____.

A．their misunderstanding of facial emotions of others

B．their lack in knowledge of emotion recognition

C．their in­born tendency toward violence or aggression

D．their experience of being offended by others on purpose

3.The method Munafo and his colleagues used in their research is ________.

A．field investigation

B．case study

C．observation and analysis

D．experiment and comparison

4.What happens to the participants after receiving certain feedbacks?

A．They can interpret unclear facial expressions.

B．They put an end to their aggressive behavior.

C．They tend to judge the in­between faces positively.

D．It makes no difference in their level of aggressive behavior.

5.Which of the following will Munafo and his group probably agree with?

A．Just smile as much as possible.

B．Misunderstanding is the root of violence.

C．Seeing smiles can lower aggression.

D．Control our anger to avoid violence and aggression.
