A new iphone application Mealsnap may help. Users just need to take a picture of the meal with the phone, and it will give a calorie read-out almost immediately. Mealsnap was developed by DailyBurn, a health social network that focuses on helping its users lead healthier lifestyles. It has created several other health and diet-related iphone applications. The applications gives users a quick reply. To do that, it matches the taken picture to a databank containing the calorie information of nearly 500,000 kinds of food. Users then get the range of calories for the meal that is photographed. We started with something simple -- an apple. A couple of minutes later the application replied that it was an apple and between 64 and 96 calories. More impressive was the reply we received after sending a photo of mixed salad bowl. Mealsnap replied that the bowl contained "yellow rice with corn, boiled eggs and beans" and that the food was between 532 and 798 calories. Mr. Smith, director of DailyBurn, said that usual calorie counting needed a long time, but that the application made it easier to know the calories in food. That's why it is so popular among those who are trying hard to lose weight. In addition, Mealsnap can serve as a food diary. No need to write down what they've eaten, the photos will be stored. Then users can keep a visual log . Mr. Smith said: "It's like a food journal, but easier. All you do is to take the picture. The simple act of recording something can cause a psychological change that can help people on their health journey. Knowing the calorie range makes me think more about what I'm eating. Question: 61.

Read the following article and select the best answer. Article: Our lives and our songs Do you ever listen to the songs that your parents like? Chances are that you don't. You probably think the music that they like is old and dull and that the songs on your playlist are much cooler. But here is what scientists found recently : People's music tastes change as they age, according to a study published in the Journal of Personality and Social Psychology. So it is likely that your own musical preferences will follow a similar path to your parents', whether you like it or not. We used to think that culture and personality are the only factors that affect one's music choice. But researchers at the University of Cambridge, UK, gathered data from more than 250,000 people over the past 10 years. They noticed that as people age, their social circumstances change, and so does their music taste. There are three musical periods that people pass through as they mature -- "intense ", "contemporary" and " sophisticated ". The first period comes in the teenage years , during which people like intense music such as punk and rock because teenagers tend to be aggressive and want to establish their identities as independent individuals. But as people move into early adulthood, their lifestyle changes --they socialize more and want to build close relationships with others. As a result, they become more fond of contemporary music ,such as pop and R&B, which is usually uplifting and danceable and played at parties where people hang out together and chat. When middle age comes, things have settled down for most people. This period will be dominated by more "sophisticated" music, such as jazz and classical, as well as more catchy music like country, folk and blues. " For many , this life stage is frequently exhausted by work and family, and there is a requirement for relaxing , emotive music,"Jason Rentfrow, a research member , told The Telegraph. But you must be thinking : "Aren't there old people who are still into rock music ?" Of course there are.... Question: Which of the following statements about musical periods is TRUE according to the article.? - People in their teenage years prefer pop music to rock music. - People's music tastes tend to settle down as they age. - Jazz and classical music help adults develop their identities. - Pop and blues ane dull and boring in the eyes of most middle-aged people.
