PASSAGE

P1Sometimes we get some "surprises" on our phone. For example, after you mark a song as a favourite on a music app, it recommends songs of the same kind to you. 26

P2Data is no longer only about numbers, but information about almost every part of life: Where we go, what we do and what we like and dislike. 27

P3Big Data makes life easier. The smart traffic system in Los Angeles is a good example. It collects real-time traffic data and controls 4,500 traffic lights in the system. 28 A supermarket named Tesco will recommend products to its customers on its website after knowing their shopping habits. 29

P4However, Big Data causes serious problems about how we protect our privacy. 30

P5Though there are bad sides, Big Data is helpful in people's lives in some ways. What we should do is to make the best use of it.
