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

A new study found that inner-city kids living in neighborhoods with more green space gained about 13% less weight over a two-year period than kids living among more concrete and fewer trees. Such findings tell a powerful story. The obesity epidemic(肥胖症的流行)began in the 1980s, and many people think it results from increased portion（食物） sizes and inactivity , but that can't be everything. Big Macs and TVs have been with us for a long time. "Most experts agree that the changes were related to something in the environment," says Thomas Glass of the Hopkins School of Public Health. That something could be a shrinking of the green.
The new research, published in the American Journal of Preventive Medicine, isn't the first to associate greenery with better health, but it does get us closer to identifying what works and why. At its most straightforward, a green neighborhood simply means more places for kids to play — which is important since time spent outdoors is one of the strongest links to children's activity levels.
Glass warns that most studies don't necessarily prove a link between greenness and health, but they're helping spur action. In September the U.S. government approved the No Child Left Inside Act to encourage public initiatives (积极性)aimed at exposing kids to the outdoors.
Finding green space is, of course, not always easy, and you may have to work a bit to get your family a little grass and trees. If you live in a suburb or a city with good parks, take advantage of what's there. Your children in particular will love it — and their bodies will thank you.According to the passage, what might cause children’s inactivity?

When elephants retire, many head for the Elephant Sanctuary in Hohenwald, Tenn. They arrive one by one, but they tend to live out their lives two-by-two. "Every elephant that comes here searches out someone that she then spends most all of her time with," says sanctuary co-founder Carol Buckley. It's likely having a best girlfriend, Buckley says - "Somebody they can relate to, they have something in common with."
Debbie has Ronnie. Misty can't live without Dulary. Those are pachyderm-pachyderm pairs. But perhaps the closest friends of all are Tarra and Bella. Tarra, an 8,700 pound Asian elephant; Bella, a stray dog, are closest friends.
Bella is one of more than a dozen stray dogs that have found a home at the sanctuary. Most want nothing to do with the elephants and vice versa. But not this odd couple. "Bella knows she's not an elephant. Tarra knows she's not a dog," Buckley adds. "But that's not a problem for them." "When it's time to eat they both eat together. They drink together. They sleep together. They play together," Buckley says.
Tarra and Bella have been close for years — but no one really knew how close they were until recently. A few months ago Bella suffered a spinal cord injury. She couldn't move her legs, couldn't even wag her tail. For three weeks the dog lay motionless up in the sanctuary office. And for three weeks the elephant held vigil: 2,700 acres to roam free, and Tarra just stood in the corner, beside a gate, right outside that sanctuary office. "She just stood outside the balcony - just stood there and waited," says Buckley. "She was concerned about her friend." Then one day, sanctuary co-founder Scott Blais carried Bella onto the balcony so she and Tarra could at least see each other.
"Bella's tail started wagging. And we had no choice but to bring Bella down to see Tarra," Blais says.
They visited like that every day until Bella could walk. Today, their love — and trust — is stronger than ever. Bella even lets Tarra pet her tummy - with the bottom of her enormous foot. They harbor no fears, no secrets, no prejudices. Just two living creatures who somehow managed to look past their immense differences.
Take a good look at this couple, human beings. Take a good look at the world. If they can do it — what's our excuse?The underlined part “Those are pachyderm-pachyderm pairs.” in Para. 2 means ______.

LONDON ( Reuters)-- Ecotourism (生态旅游) is causing a lot of damage to wildlife and may be endangering the survival(生存) of the very animals people are flocking to see, according to researchers.
Biologists and conservationists (自然环境保护论者) are worried because polar bears, dolphins, penguins and other creatures are getting stressed and losing weight and some are dying.
“Evidence is growing that many animals do not react well to tourists in their backyard,” New Scientist magazine said.
The immediate effects researchers have noticed are changes in behavior, heart rates, or stress hormone levels but they fear it could get much worse and over the long term “could endanger the survival of the very wildlife they want to see”.
Although money produced through ecotourism, which has been growing at about 10--30 percent a year, has major benefits for poor countries and people living in rural areas, the Swiss-based World Conservation Union (IUCN) and some governments fear not all projects are audited (审计) and based on environmentally friendly policies, according to the magazine.
“The transmission(传播) of disease to wildlife, or small changes to wildlife health through disturbance of daily life or increased stress levels, while not obvious to the casual observer, may translate to lower survival and breeding,” said Philip Seddon, of the University of Otago in Dunedin, New Zealand.
Scientists have noticed that bottleneck dolphins along the northeastern coast of New Zealand become nervously excited when tourist boats arrive. Similar changes in behavior have been observed in polar bears and yellow-eyed penguins in areas visited by ecotourists are producing smaller babies.
Conservationists are now calling for more research into the effect of ecotourism on animals and say the industry must be developed carefully. They also want studies done before new ecotourism projects are started.
“The animals’ welfare should be very important because without them there will be no ecotourism,” said Rochelle Constantine of the University of Auckland in New Zealand.What's the text mainly about?
| A．Many animals are dying because of lack of money. |
| B．There will be no ecotourism without animals. |
| C．Ecotourism could endanger the survival of the wildlife people want to see. |
| D．More research should be done on ecotourism. |
According to New Scientist magazine, more and more evidence has come to suggest that _____.
| A．polar bears are getting stressed |
| B．other creatures are losing weight |
| C．many animals do not respond well to travellers in their backyard |
| D．All of the above |
Which of the following is NOT mentioned in the text?
| A．Ecotourism may endanger the survival of some animals. |
| B．Polar bears in areas visited by ecotourists are producing smaller babies. |
| C．Ecotourism has been growing at about 10--30 percent a year. |
| D．Studies should be done before new ecotourism projects are started. |
A scientist turns out to be able to see the future by offering each of some four-year-olds a piece of candy and watching how he or she deals with it. Some children reach eagerly for the treat they see. Some last a few minutes before they give in. But others are determined to wait until the last moment.
By the time the children reach high school, something remarkable has happened. A survey found that those who as four-year-olds had enough self-control to hold out generally grew up to be more popular, adventurous, confident and dependable. The children who gave in to temptation early were more likely to be lonely, easily frustrated and inflexible.
Actually, the ability to delay reward is a sign of emotional intelligence which doesn’t show up on an IQ test.
The hardware of the brain and the software of the mind have long been scientists’ concerns. But brain theory can’t explain what we wonder about most, like the question why some people remain upbeat in the face of troubles that would sink a less resistant soul.
Here comes the theory of Daniel Goleman, writer of Emotional Intelligence: when it comes to predicting people’s success, brain ability as measured by IQ may actually matter less than the qualities of mind once thought of as “character”.
EQ is not the opposite of IQ. What researchers have been trying to understand is how they work together; how one’s ability to handle stress, for instance, affects the ability to concentrate and put intelligence to use. Among the elements for success, researchers now generally agree that IQ counts for about 20%; the rest depends on everything from social class to luck.
While many researchers in this relatively new field are glad to see emotional issues finally taken seriously, some few fear EQ invites misuse.The experiment with the four-year-olds makes it clear that ______.
| A．the age of 4 is a proper time for scientific experiment |
| B．emotional intelligence won’t show up until adolescence |
| C．candy can be used to measure a person’s emotional intelligence |
| D．the ability of self-control plays a role in personal success |
Which of the following is True of EQ and IQ according to the text?
| A．Scientists are trying to discover the way in which EQ and IQ work together. |
| B．The higher a person’s IQ is, the higher his or her EQ is. |
| C．Some people can be blessed with lots of both, but some with little of either. |
| D．There is no link between EQ and IQ. |
The underlined word “upbeat” in Paragraph 4 probably means ______.
| A．optimistic | B．floating |
| C．excited | D．kind |
What is most likely to be written in the paragraph that follows?
| A．Information about famous people with high EQ. |
| B．Some reasons why EQ is a relatively new field. |
| C．Examples showing the opposite voice about EQ. |
| D．Strong demand for basic emotional education. |
People aren’t walking any more--- if they can figure out a way to avoid it.
I felt superior about this matter until the other day I took my car to mail a small parcel. The journey is a matter of 281 steps. But I used the car. And I wasn’t in any hurry, either, I had merely become one more victim of a national sickness: motorosis.
It is an illness to which I had thought myself immune, for I was bred in the tradition of going to places on my own two legs. At that time, we regarded 25 miles as good day’s walk and the ability to cover such a distance in ten hours as a sign of strength and skill. It did not occur to us that walking was a hardship. And the effect was lasting. When I was 45 years old I raced –and beat—a teenage football player the 168 steps up the Stature of Liberty.
Such enterprises today are regarded by many middle-aged persons as bad for the heart. But a well-known British physician, Sir Adolphe Abrhams, pointed out recently that hearts and bodies need proper exercise. A person who avoids exercise is more likely to have illnesses than one who exercises regularly. And walking is an ideal form of exercise--- the most familiar and natural of all. It was Henry Thoreau who showed mankind the richness of going on foot. The man walking can learn the trees, flower, insects, birds and animals, the significance of seasons, the very feel of himself as a living creature in a living world. He cannot learn in a car.
The car is a convenient means of transport, but we have made it our way of life. Many people don’t dare to approach Nature any more; to them the world they were born to enjoy is all threat. To them security is a steel river thundering on a concrete road. And much of their thinking takes place while waiting for the traffic light to turn green.
I say that the green of forests is the mind’s best light. And none but the man on foot can evaluate what is basic and everlasting.What was life like when the author was young?
| A．people often walked 25 miles a day |
| B．People usually went around on foot. |
| C．People used to climb the Statue of Liberty. |
| D．people considered a ten-hour walk as a hardship. |
The author mentions Henry Thoreau to prove that ________.
| A．middle-aged people like getting back to nature |
| B．people need regular exercise to keep fit |
| C．walking in nature helps enrich one’s mind |
| D．going on foot prevents heart disease |
What is compared to “a steel river” in Paragraph6?
| A．A ray of traffic light | B．A queue of cars |
| C．A flash of lightning | D．A stream of people |
What is the author’s intention of writing this passage?
| A．To encourage people to return to walking. |
| B．To recommend people to give up driving |
| C．To advise people to do outdoor activities. |
| D．To tell people to reflect more on life. |
