Worried about how many calories( ) you are going to get in that piece of pizza, chocolate cake or bag of chips? A new iPhone application that takes a picture of the meal with the phone and gives a calorie read-out almost at once, may help. The MealSnap was developed by DailyBurn, a fitness social network that has created several other fitness and diet-related iPhone applications. Within minutes of taking a picture of a meal and matching it to the given information of some 500, 000 kinds of food, the application sends users a warning with a range of calories for the meal that was photographed. To start with, we sent it something simple--a Braeburn apple. A couple of minutes later the application replied that it was between 64 and 96 calories. Andy Smith, chief director at DailyBurn, said: "The database can also quickly help recognize the food, how many calories there are, proteins, fat, carbs, vitamins, whatever you may want to know." Mr Smith added that it will take some time to complete calorie counting but the application makes it easier to record the calories in food. That is why it is so popular among those who are trying hard to lose weight. "The pure act of recording something can cause a psychological change that can help people on their health and fitness plan. Just the simple fact of recording it makes me more understand what I'm eating," he said. In addition, MealSnap can serve as a food diary, allowing users to keep a readable record of the meals they have eaten. Mr Smith said:"It's like a food journal, but easier. All you do is take the picture." MealSnap is available on the iTunes store for PS1.79, or $2,99 in the US. What is the best title for the passage? A) iPhones Win Against Apples in Market B) MealSnap iPhones Work as a Health Signal C) MealSnap, a New iPhone Application D) MealSnap Offers You Health Database

One day I walked down to get to my car, thinking about what I had to accomplish and scolding myself for being late for work, but surprisingly the car was nowhere to be found. This was at 8 a.m. in the morning. I made trips to all the towing places and police stations, all the time thinking that it was towed by cops .By around 10 a.m., the cops decided that it was actually stolen. After filing a report with them, I finally got to work thinking how my day was completely messed up. Later in the day I went to pick up a rental car at Enterprise only to realize that my license was missing, too, along with my car. I told the enterprise guy the whole story and he offered to take me to the closest DMV and get a duplicate license. 1 was totally shocked. I did not know why this complete stranger would want to take some time off his day to help me. He actually took me to DMV, got a duplicate and then rented me a car. I was upset the whole day because of the events happening to me but somehow this simple act of kindness from a complete stranger made it all worth it. It cheered me up and made me forget all the troubles of the day. I was so moved by this kind act that the next day I made sure someone else got a similar surprise. I took some smiley shaped chocolates and left them on some of my colleagues' desks. There is still a lot of goodness out there in the world. We just need to take the time to notice it. I hope that this story would inspire many others like me to do more acts of kindness. We can infer that DMV is _ . A) an office for license B) a towing place C) a renting place D) a parking lot

Q: The US company iRobot made a new kind of sub-marine , called the Seaglider, last week. The robotic submarine was developed by researchers at the University of Washington. It is about 1.8 meters long and weighs about 52 kilograms. It moves through water at a speed of up to 20-25 kilometers a day and can stay at sea for up to six months before needing a battery recharged. This special character results from its special propulsion system . Unlike a traditional submarine, the Seaglider does not have a propeller . It has an air tank that is emptied and filled to adjust depth, as well as a pair of wings that help to guide and lead the submarine. A traditional submarine, on the other hand, "puts water inside tanks to make it heavier, or it will expel the water to make it lighter," explained Frederick, a professor at the University of Washington. Each time the Seaglider comes to the surface, it sends the data which it collects to its controllers by satellite. Operators can also send the submarine new information. For example, they can change its course in their office through giving the computer orders. Seagliders are already being used for scientific research, such as environmental studies. iRobot also hopes to sell the submarine to the military . At $100,000 each, the Seaglider is a cheap way to keep an eye on the ocean. "These things can go out there and monitor large areas of ocean because they're very persistent. They can go for thousands of miles on their own. At the same time, you can tell them to stay in one place and they can circle," says Helen Greiner, chairwoman of iRobot. "This is science fiction stuff in many ways, but it's really out there and working." Nowadays, the Seaglider is being used only _ . A) by the military B) in science fiction C) by the government D) in scientific research
A: D

When you have a question about something, where do you go? For many people the answer is simple as they can go online to a search engine like Google or Yahoo. But what about people in rural or underdeveloped areas who may have no way to get on the Internet? A business and international development professor in California, Rose Shuman, found an answer for them: Question Box. Question Box is a service that provides answers---free of charge---for people who cannot search the Internet directly. The users of Questions Box might be those who might not be able to read, or simply have no access to the Internet. Question Box began three years ago in India. People used a metal call box with a push-to-talk button to connect a live operator. Rose Schuman explained," You just need to push a big green button on the box which will connect you directly to our operators who are sitting in front of computers, and speak your language. You can ask them any sort of question you want, and they'll look it up in English or in Hindi, or whatever the main language is, and translate the answer back for you." The service is currently offered in two villages. The latest version of the box uses mobile phone technology, and solar panels in case the electrical power fails. Rose Shuman says the aim was to make the box as easy as possible for users, "It is very efficient . Rather than try to bring a lot of difficulties to them and expect them to spend a lot of time to learn how to use the Internet, the idea was to make a technology that even Grandma could use." In April 2009, Question Box was introduced to Uganda. Forty community workers with mobile phones connected villagers to call center operators in Kampala. The community workers went around telling people about the service. They wore T-shirts that said "Ask me." But Internet service in Uganda proved slow and undependable. So Question Box teamed up with a local technology company to store information on a local server. That way, the researchers in Kampala could quickly search... In Rose Schuman's opinion, the greatest advantage of Question Box is that _ . A) it is the most advanced in the world B) it is more convenient to carry. C) it saves much more energy D) it is much easier to use
