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.

Because earthquakes happen without warning, it’s important to take measures now to prepare. Because you don’t know where you will be when an earthquake happens, prepare some supplies for your home, workplace, and car.
1. Water
A person needs at least 1/2 gallon(加仑) of water daily just for drinking. Store at least 1 gallon of water per person per day and be prepared for a 72-hour period. It is suggested that you buy bottled water. Keep bottled water in its original container and do not open it until you need to use it. Also, do check the “use by” date.
2. Food
It’s always a practical idea to keep a supply of non-perishable(不易腐烂的) food on hand. Have an enough supply of canned food, powdered milk, dried fruits, non-salted nuts and canned juices for at least 72 hours.
3. Torch(手电筒) and spare batteries (电池)
Keep a torch beside your bed, at your place of work, and in your car. Do not use matches or candles after an earthquake until you are sure that no gas leaks(泄露).Prepare a battery-powered radio and spare batteries. Most telephones will be out of order, so radios will be your best source of information.
4. Clothes

小题1:Why should people prepare themselves for an earthquake?| A．Because earthquakes can be known before they happen. | | B．Because earthquakes take place without warning. | | C．Because earthquakes usually take place in the neighborhood. | | D．Because it’s people’s daily work to prepare the earthquakes. |

A simple piece of clothesline hangs between some environmentally friendly Americans and their neighbors．
On one side stand those who see clothes dryers （干衣机） as a waste of energy and a major polluter of the environment．As a result, they are turning to clotheslines as part of the “what-I-can-do environmentalism．”
On the other side are people who are against drying clothes outside, arguing that clotheslines are unpleasant to look at．They have persuaded Homeowners Associations （HOAs） access the U．S．to ban outdoor clotheslines, because clothesline drying also tends to lower home value in the neighborhood．
This has led to a Right-to-Dry Movement that is calling for laws to be passed to protect people’s right to use clotheslines．So far, only three states have laws to protect clothesline．Right-to-Dry supporters argue that there should be more．
Matt Reck, 37, is the kind of eco-conscious（有生态意识的）person who feeds his trees with bathwater and reuses water drops from his air conditioners to water plants．His family also uses a clothesline．But on July 9, 2007, the HOA in Wake Forest, North Carolina, told him that a dissatisfied neighbor had telephoned them about his clothesline．The Recks paid no attention to the warning and still dried their clothes on a line in the yard．“Many people say they are environmentally friendly but they don’t take matters into their own hands,” says Reck．The local HOA has decided not to take any action, unless more neighbors come to them．
North Carolina lawmakers are saying that banning clotheslines is not the right thing to do．But HOAs and housing businesses believe that clothesline drying reminds people of poor neighborhoods．They worry that if buyers think their future neighbors can’t even afford dryers, housing prices will fall．
Environmentalists say such worries are not necessary, and in view of global warming, that idea needs to change．As they say, “The clothesline is beautiful．Hanging clothes outside should be encouraged．We all have to do at least something to slow down the process of global warming．”
小题1:One of the reasons why supporters of clothes dryers are trying to ban clothesline drying is that ______．| A．clothes dryers are more efficient | | B．clothesline drying reduces home value | | C．clothes dryers are energy-saving | | D．clothesline drying is not allowed in most U．S．states |
小题2:Who are in favor of clothesline drying? | A．Housing businesses. | | B．Environmentalists． | | C．Homeowners Associations． | | D．Reck’s dissatisfied neighbors． |
小题3:What is mainly discussed in the text? | A．Clothesline drying: a way to save energy and money． | | B．Clothesline drying: a lost art rediscovered． | | C．Opposite opinions on clothesline drying． | | D．Different varieties of clotheslines． |

Vending machines （投币式自动售货机） are found in 16% of U．S．elementary schools, 52% of middle schools and 88% of high schools．About 22% of students in grades 1 through 12 buy food in vending machines each day—and those purchases added an average of 253 calories to their diets, according to a new study in the September issue of the Journal of School Health．
Just to be clear, those were not 253 calories" worth of tofu, yogurt or carrot．The most popular vending machine items included soft drinks, candy, chips, crackers, cookies, cakes and ice cream．On the plus side （好的方面）, kids also bought low-fat milk, fruit juice and even fruit, the study found．
But the eventual effect on kids" diets was not good．Those who bought from vending machines ate an average of 156 grams of sugar per day, compared with 146 grams for those who abstained （节制）．They also consumed less fiber, iron and vitamin B．
One silver lining: Vending machine customers ate 4% less sodium （钠） than other students--an average of 3,287 milligrams per day compared with 3,436 mg for those who didn"t buy from vending machines．That"s probably because the extra snacks made kids too full to eat as much at mealtimes, when dishes are especially Salty．In any event, kids should eat no more than 1,200 to 1,500 mg of sodium each day, according to the Mayo Clinic．Even for adults, the government recommends a daily limit of 2,300 mg．
Overall, vending machines in school appear to be a threat to children"s health．The researchers calculated that all that snacking adds up to about14 extra pounds per child per school year．For some students this might be a serious contributor to weight issues．The study was based on data collected from 2,309 children nationwide for the third School Nutrition Dietary Assessment Study, which was
conducted by the U．S．Department of Agriculture"s Food and Nutrition Service．
小题1:The students using vending machines take in less of all the following EXCEPT ．| A．sugar | B．fiber | C．vitamin | D．iron |
