Consumers will consider it“always delightful and thoroughly mine,”Microsoft CEO Steve Ballmer said at a launch event. Ballmer said last year that Microsoft had“screwed up”with its Windows Mobile operating system.For example,it failed to keep up with touch-screen innovations that make iPhones and Android phones easy to use.
Microsoft fell from third to fourth place in market share this year,behind BlackBerry,iPhone and Android. Only 10.8% of smartphone owners used Microsoft’s system in August,down from 18% last December.
But Windows Phone 7 is“a total departure from anything they’ve done”.Microsoft says it sought to simplify common activities. For example,you can instantly take a picture with a phone’s camera by pushing a button on the device. You don’t have to first awaken it from its sleep mode and launch the camera application. You also can program the phones to automatically upload photos to Facebook or other social network sites in a couple of seconds. Users can easily work with Microsoft Office contact and calendar information as well as documents created in Microsoft’s Word,Excel and PowerPoint.
The phones will not show videos built on Adobe’s Flash platform,widely used by services including YouTube and Hulu.
AT&T will offer the first Windows Phone 7 smartphone,the Samsung Focus,on Nov.8.Soon after,it will have the LG Quantum and HTC Surround. Each will cost S| 199.99 with a two-year service contract. T-Mobile will have two Windows Phone 7 models out for the holiday shopping season:the HTC HD7 and Dell Venue Pro. It did not say how much they’ll cost.

Studies are moving closer to designing robots that could do dangerous work, create prosthetic limbs(假肢)for humans that work much better than in the past, or even help some people who use wheelchairs to get “walking” abilities.
“Researchers have been working toward robot movement for a long time,” said Jonathan Hurst, a professor at OSU. “What we’ve done is to study what behavior is really possible for a robot.”
The movement of humans and other animals is difficult to copy. Using little energy, they can move easily over hard areas, and enjoy balance from muscles(肌肉). They have different ways to deal with forces, such as holding something hard in place rigidly(牢牢地), like the act of holding a cup of coffee level during a car ride. In their recent studies, the OSU researchers proved that these two abilities are mutually exclusive(相互排斥的). Humans deal with this problem by using pairs of muscles. For a robot, the more it’s able to do one of these tasks, the less able it is to do the other.
Presently, robots that can walk and run must be as rigid as possible while walking. But this way uses a lot of energy. The OSU researchers are working toward something that has similar or better performance, but uses far less energy, and is closer to the abilities of animals.
“So there’s no reason why we shouldn’t be able to build robots with good movement ability,” Hurst said. “Clearly this might be useful in highly dangerous situations. But I could also see great improvements possible with prosthetic limbs that work much better than present technology. ”

Scientists know that climate change has a major effect on the Arctic Ocean partly because sea ice is disappearing. They also know that areas of open seawater are expanding. Such areas are known to take in sunlight and increase temperatures. Scientists say this has helped to cause the loss of the Arctic’s ice cover.
For the study, the American scientists compared eighteen computer programs with observations made by satellites and other instruments. The Intergovernmental Panel on Climate Change used the computer programs to prepare its 2007 estimates of climate change.
The computer programs gave estimates of the amount of ice in the Arctic Ocean in the month of September. September is when the Arctic has the least ice, after the warm, summer months. The computer estimates suggested an ice loss of two and a half percent for every ten-year period between 1953 and 2006.
Newer studies of the Arctic have used information gathered by aircraft, satellites and ships. This information showed a loss of September ice cover of almost eight percent for every ten-year period between 1953 and last year. This means the ice is disappearing about thirty years faster than the computer programs estimated.
The scientists say the programs might not have recognized the full effect of increased carbon dioxide and other gases in Earth’s atmosphere. They say their study suggests the gases may have more of an effect than had been thought.
小题1:It is reported that sea ice in the Arctic Ocean is melting more quickly than expected mainly because _________.
A.climate change | B.sea ice’s disappearance |
C.seawater’s expansion | D.the loss of the Arctic’s ice cover |
A.The scientists have been observing the Arctic Ocean for many years. |
B.The scientists have compared the computer programs with observation made by satellites and other instruments. |
C.The scientists have figured out many numbers with the help of computer. |
D.The scientists have found that the seawater take in sunlight and increase temperatures. |
A.22.5% | B.35% | C.72% | D.100% |
A.The figures of the computer estimates are wrong. |
B.Scientists study climate change through studying sea level. |
C.Newer studies show gases may have more effect on sea ice in the Arctic Ocean. |
D.The ice is melting even faster than satellites have estimated. |
A.prevent the sea ice in the Arctic Ocean from melting any more |
B.pay more attention to the loss of the Arctic’s ice cover |
C.take necessary steps to protect the environment of our earth |
D.stop summer sea ice in the Arctic from disappearing so fast |
What the scientists say is that dogs that exhibit anxiety when left home alone by their owners may have bigger problems — they may be in a permanent bad mood.
This pessimistic outlook may not otherwise be easily apparent in a dog’s other characteristics, like running speed or learning ability, the study reports.
Dogs are similar to humans in the role that emotional state plays in decision making, said Michael Mendel, a veterinary scientist at the University of Bristol and the study’s lead author. The study’s researchers looked at 24 dogs in shelters in Britain.
They placed the dogs in isolated settings and observed their reactions — many barked, jumped on furniture and scratched at the door.
Then they placed bowls in two rooms. One bowl contained food, while another was empty. After training the dogs to understand that bowls can sometimes be empty, and sometimes full, they began to place bowls in ambiguous locations.
Dogs that quickly raced to the locations were more optimistic, and in search of food. Those that did not were deemed pessimistic.
The more separation anxiety a dog expressed while in isolation, the more likely the dog was to have a pessimistic reaction, the researchers found.
The study carries an important message for dog owners, Dr. Mendel said.
Dogs that express serious anxiety when alone may need treatment, as it could be a sign of unhappiness and instability.

D.Dogs can always find the bowl with food quickly. |
A.Dogs will be optimistic as long as they are left alone. |
B.Dogs must be in a permanent bad mood when their owners left. |
C.Dogs that express anxiety don’t need treatment. |
D.Dogs may easily show their pessimistic outlook in learning ability. |
Pointing to a quilt and clothes he received from the local government, he said: “These are all I have. My home collapsed in the quake, and everything in the town was flooded.”
He used to live in Xuanping town of Beichuan county which was destroyed by the quake. Adding to his misery, rivers blocked by landslides(山崩) led to flooding in the town.
But Liu said he was lucky because he was healthy, otherwise he would not have the energy to walk 10 hours on damaged and dangerous mountainous roads to escape the flood on Monday. He said the trip used to take him about 90 minutes when the roads were in good condition.
The journey was difficult and “rocks kept falling,” he said, showing injured legs and black, split toenails.
Liu said his three sons were working in eastern cities as migrant workers.
“I’ve been living alone in the mountains for more than 20 years. My wife died 30 years ago,” he said in a low voice.
During his journey to Mianyang, Liu said he saw many elderly people who chose to stay.
“Soldiers were persuading them to leave for fear of floods,” he said.
Talking about his home before the quake struck, Liu’s mood lifted. “I raised pigs and chickens, and grew vegetables. I could have rice, meat and greens almost every day,” he said.
“But now, I have only biscuits and instant noodles.”
Liu said one of his sons returned home from Wenzhou, Zhejiang Province, after the quake, but left because the father refused to go with him.
“I don’t want to leave home. And I know it is difficult for them out there. How could I add to their burden?” he asked, his eyes red.
“I still want to go back to my home. Given a small piece of land, I could live by myself.”
It is learnt that resettlement plans for displaced people have not been finalized.
However, not every elderly person is as strong-willed as Liu.
Psychologists said the elderly need as much comfort as children. Lu Jianguo, a psychologist from Chengdu Medical College, said “We will first let them cry and tell their stories, and then help them regain confidence.”
小题1:Which of the following is TRUE according to the passage?
A.Liu Yaorong spent 8.5 hours more than usual covering the roads in escaping the flood. |
B.The flood was followed by an earthquake in Xuanping in the same day. |
C.Liu Yaorong was in time to escape the quake without being hurt. |
D.Being healthy, Liu Yaorong was the only old man to escape the flood. |
A.happiness | B.fortune | C.puzzle | D.suffering |
A.Positive. | B.Negative. | C.Aggressive. | D.Dependent. |
A.Elderly react more quickly to flood disaster |
B.Elderly try hard to deal with quake disaster |
C.Elderly prefer to stay at their own home |
D.Elderly are well cared for by government |
This year some twenty-three hundred teenagers(young people aged from13~19)from all over the world will spend about ten months in U.S. homes. They will attend U.S. schools, meet U.S. teenagers, and form impressions of the real America. At the same time, about thirteen hundred American teenagers will go to other countries to learn new languages and gain a new understanding of the rest of the world.
Here is a two-way student exchange in action. Fred, nineteen, spent last year in Germany with George’s family. In turn, George’s son Mike spent a year in Fred’s home in America.
Fred, a lively young man, knew little German when he arrived, but after two months’ study the language began to come to him. School was completely different from what he had expected—much harder. Students rose respectfully when the teacher entered the room. They took fourteen subjects instead of the six that are usual in the United States. There were almost no outside activities.
Family life, too, was different. The father’s word was law, and all activities were around the family rather than the individual. Fred found the food too simple at first. Also, he missed having a car.
“Back home, you pick up some friends in a car and go out and have a good time. In Germany, you walk, but you soon learn to like it.”
At the same time, in America, Mike, a friendly German boy, was also forming his idea. “I suppose I should criticize(批评)American schools,” he said. “It is far too easy by our level. But I have to say that I like it very much. In Germany we do nothing but study. Here we take part in many outside activities. I think that maybe your schools are better in training for citizens. There ought to be some middle ground between the two.”
小题1:This year ________teenagers will take part in the exchange programme between America and other countries.
A.twenty-three hundred |
B.thirteen hundred |
C.over three thousand |
D.less than two thousand |
A.help teenagers in other countries know the real America |
B.send students in America to travel in Germany |
C.let students learn something about other countries |
D.have teenagers learn new languages |
A.America food tasted better than German food |
B.German schools were harder than American schools |
C.Americans and Germans were both friendly |
D.There were more cars on the streets in America |
A.there is some middle ground between the two teaching buildings |
B.there are a lot of after-school activities |
C.students usually take fourteen subjects in all |
D.students go outside to enjoy themselves in a car |
