(35-36)Many people have a smartphone today. Smartphones are very useful and make our lives easy. People use them to takepictures, make phone calls, and play music. They are wonderful and changed our lives so much. However, smartphones arebecoming a big problem in the USA. How? People are using them when they shouldn’t. Drivers are sending text messages whendriving. People are walking and talking on the phone at the same time. Science tells us our brains can only do one thing at atime. When we try to do more things, we become “blind” to things around us.When people are busy using their smartphones, they do not notice other people and things around them. More people aregoing to the hospital because they got hurt texting and walking. Drivers talking on the phone do not notice other drivers and hitthem. In both problems, more and more deaths are happening. Police officers are working hard and trying to catch these peopleand give them a fine. These fines can be from $50 to $2000, and in some parts of USA, people can also be arrested by policeofficers and go to jail.☺ send text massages 傳訊息 brain 大腦 blind 盲 notice 注意 death 死亡 go to jail 坐牢
