With the modern technology developing,the mobile phone becomes more and more popular in our life.Sometimes we find out that we could hardly do anything without it.We keep in touch with those we know by phone.We call our friends to discuss where and when we meet.We call the restaurants to order take-away food.We even have meetings through the phone with our coworkers when we can't come back...It's no doubt that phones make our life more convenient and effective,but it makes us lazier at the same time.More and more people complain that people today are not so close as we used to be.So you see,everything has two sides--positive side and negative side.We can't blame the phone.We just need to find a balance.
