If someone is drowning(溺水) If you can’t swim. don’t get into the water. Cry out for help.

Life for almost anyone is increasingly influenced by screens. Not only are screens themselves cheap to make, but they also make things cheaper. Any place that can fit a screen in can cut costs. And any activity that can happen on a screen becomes cheaper. The physical experience of learning, living and dying is becoming smooth glass. All of this has led to a curious new reality: Human contact is becoming a luxury good (奢侈品).

“What we are seeing now is the luxury of human engagement,” Milton Pedraza, the chief of the Luxury Institute, said. Expected spending on experiences such as enjoyable travel and dining is outpacing spending on goods, according to his company’s research, and he sees it as a direct response to the rapid increase of screens.

Screens exposure starts young. And children who spent more than two hours a day looking at a screen got lower scores on thinking and language tests, according to early results of a landmark study supported by the National Institutes of Health. The study focuses on brain development of more than 11,000 children. Most disturbingly, the study is finding that the brains of children who spend much time on screens are different. For some kids, their cerebral cortex (大脑皮层) would become thinner before expected time. In adults, one study found an association between screen time and depression.

There is also the reality that in our culture of increasing separation, in which so many of the traditional gathering places and social structures have disappeared, screens are filling a vital gap.

For normal people, running away from the screen becomes impossible. It’s not a luxury, and it’s easy to get. It is normal for more people to need the network constantly. In addition, it has become an important part of social interaction.

The Power of the Press

In modern countries any efforts to restrict the freedom of the press are rightly condemned. However, this freedom can easily be abused. 【小题1】 Though we may enjoy reading about the lives of others, it is extremely doubtful whether we would equally enjoy reading about ourselves. Acting on the contention that facts are sacred, reporters can cause untold suffering to individuals by publishing details about their private lives. Newspapers exert such tremendous influence that they can not only bring about major changes to the lives of ordinary people but can even overthrow a government.

The story of a poor family that acquired fame and fortune overnight, dramatically illustrates the power of the press. The family lived in Aberdeen, a small town of 23, 000 inhabitants in South Dakota.   【小题2】 They were expecting their sixth child and were faced with even more pressing economic problems. If they had only had one more child, the fact would have passed unnoticed. They would have continued to struggle against economic odds and would have lived in obscurity. But they suddenly became the parents of quintuplets, four girls and a boy, an event which radically changed their lives. The day after the birth of the five children, an aeroplane arrived in Aberdeen bringing sixty reporters and photographers.

The rise to fame was swift. 【小题3】 Newspapers and magazines offered the family huge sums for the exclusive rights to publish stories and photographs. Gifts poured in not only from unknown people, but from baby food and soap manufactures who wished to advertise their products. The old farmhouse the family lived in was to be replaced by a new $ 500, 000 home. Reporters kept pressing for interviews so lawyers had to be employed to act as spokesmen for the family at press conferences. While the five babies were still quietly sleeping in oxygen tents in a hospital nursery, their parents were paying the price for fame. 【小题4】 They had become the victims of commercialization, for their names had acquired a market value. Instead of being five new family members, these children had immediately become a commodity.
