A study found most people use their smart phones for an hour and 52 minutes a day. Most of this time is taken up with texting, emails and surfing the web, but only around 20 minutes is spent making three calls. The survey of 2,000 people found that social media apps, calculators , calendars and cameras were also seen as particularly important functions. Navigation apps such as Google Maps were popular too - with one in six people admitting they would feel unable to travel around an unfamiliar city without _ . The study also found checking Facebook and taking pictures of others are carried out more frequently than making calls. Also on the list were the calendar to remember appointments and birthdays, mobile banking and the news are apps that make day-to-day life a little easier. Tom Barr said: 'The functions on a mobile phone have developed and improved drastically over the past 10 years. With so many ways to keep in touch nowadays, people are using the functions that are convenient for them. As we get less and less time to ourselves, we need more convenience in our lives and less difficulty. While calling can be more personal, it doesn't always save your time.' Scientists at Rice University wanted to see if the latest mobile technology would be used by the students to improve their learning. But a year later, the researchers concluded that it's not enough to give students the right technology, but said they need guidance about how to use it. Why don't most people make a lot of calls? A) Because calling can be more personal. B) Because it doesn't always save your time. C) Because social media apps are important functions. D) Because calling is more convenient.

While we are still children ,most of us live at home with our parents, more or less peacefully . But as we become teenagers , things change ,and we begin to grow apart from our parents . This means we are almost ready to leave the house where we grew up and make a new home of our own . All humans must do this ,but they don't all do it in the same way . If ,for instance ,you belong to a primitive tribe ,then as you grew up ,you'd learn the skills you needed as an adult---how to catch fish ,how to keep the house and look after children . You would be ready to marry in your early teens and you would build a house and live near your family in the village. This seems a very old way of life , but it is what humans have been used to through hundreds of years. And it is what we are still used to in the 21stcentury ,for man hasn't changed in the short time since he became civilized . But could you leave home and look after yourself during the teen years ? Most people would not do very well . Why ? Because although man hasn't changed very much , the society he lives in has changed greatly ,which means that we have to learn more and more before we are ready to leave our parents' shelter( ) and live alone . However ,sometimes it is very frustrating to live at parents' home . Parents can be very upset about late nights ,criticizing friends and always saying that we are noisy and dirty . But we still need our emotional shelter till we finish our studies , and that is why we usually stay in our parents' home until we feel grown up enough to deal with living alone . From the passage ,we know living at parents' home when we become teenagers _ . A) is always pleasant B) must be very exciting C) makes us feel lonely D) may be annoying
