Read the article and select the best answer. Article: 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. Question: Which of the following statements about MealSnap is TRUE? Options: A: People have to link iPhone with the Internet to use it. B: It has been put into the market. C: People will have a physical change by using it. D: It's popular because it was developed by DailyBurn.

Read the article and select the best answer. Article: Many people once thought that air pollution had a bad influence upon only the area immediately around large cities with factories and heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is nearly worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of factories and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide( ) in the air resulting from the burning of fossil fuels (coal and oil) is creating a"greenhouse effect" - holding in heat reflected from the earth and raising the world's average temperature. If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water. Another opinion, less widely held, is that increasing tiny substances in the atmosphere are blocking sunlight and lowering the earth's temperature-a result that would be equally disastrous.A drop of just a few degrees could create something close to new ice age and would make agriculture difficult or impossible in many of our top farming areas. At present we do not know for sure that either of these conditions will happen (though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we are very lucky, the two tendencies will make up for each other and the world's temperature will stay about the same as it is now. Question: It can be inferred from the passage that _ . Options: A: raising the world's temperature a little would not do much harm to life on earth B: lowering the world's temperature a little would lead to agricultural disasters C: almost no temperature changes have occurred over the past decade D: the world's temperature will remain constant in the years to come

Read the article and select the best answer. Article: Swimming is one of those activities that can be learned early in life. Little children can learn to swim as soon as they walk. In fact, you need the same skills in walking as in swimming. However, I believe that five is the best age to learn. By five or six, a child knows fear of water, a very important thing to know. It's wise to be afraid, to recognize true danger. Young ones understand that the water can sometimes be very dangerous. To really benefit from swimming, every swimmer should learn, as soon as possible, these four basic strokes; butterfly, backstroke, Breaststroke, and crawl. I feel that one of these-the breaststroke-is different from the others, since some young swimmers use this stroke naturally, without any training. In swimming there are certain rules every swimmer should follow: 1). Never swim alone! No matter how good you are in the water, don't risk drowning by swimming alone. If you swim by yourself, with no life guards or friends with you, you may get into trouble. 2). Don't go beyond your abilities. Most swimmers know enough not to swim too far from the bank or the beach, Showing off by doing dangerous tricks is no good. Swim safely and you will continue to swim and alive. 3). Don't smoke. Swimming depends on a healthy body; good lungs are part of it. 4). Work at any activity that builds muscles. Question: Little children can learn to swim as soon as _ . Options: A: they can talk B: they are five or six years old C: they have no fear of the water D: they start walking
