The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana (大麻). That is the statement of researchers who have found that tapping away on a mobile phone or computer keyboard or checking for electronic messages temporarily knocks up to 10 points off the user’s IQ. This rate of decline in intelligence compared unfavorably with the four-point drop in IQ associated with smoking marijuana, according to British researchers, who have described the phenomenon of improved stupidity as “infomania”. The research conducted by Hewlett Packard, the technology company, has concluded that it is mainly a problem for adult workers, especially men.

It is concluded that too much use of modern technology can damage a person’s mind. It can cause a constant distraction of “always on” technology when employees should be concentrating on what they are paid to do. Infomania means that they lose concentration as their minds remain fixed in an almost permanent state of readiness to react to technology instead of focusing on the task in hand. The report also added that, in a long term, the brain will be considerably shaped by what we do to it and by the experience of daily life. At a microcellular(微蜂窩，微孔的) level, the complex networks of nerve cells that make up parts of the brain actually change in response to certain experiences.

Too much use of modern technology can be damaging not only to a person’s mind, but to their social relationship. 1100 adults were interviewed during the research. More than 62 percent of them admitted that they were addicted to checking their e-mails and text messages so often that they scrutinized work-related ones even when at home or on holiday. Half said that they always responded immediately to an e-mail and will even interrupt a meeting to do so. It is concluded that infomania is increasing stress and anxiety and affecting one’s characteristics. Nine out of ten thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude.

The effects on IQ were studied by Dr. Glenn Wilson, a psychologist at University of London. “This is a very real and widespread phenomenon,” he said. “We have found that infomania will damage a worker’s performance by reducing their mental sharpness and changing their social life. Companies should encourage a more balanced and appropriate way of working.”

The city of Vienna has always been popular for its famous physicians. Around the year 1482 one such well-known physician was Dr. Paul Urssenbeck. His fame came from his ability to predict with certainty whether a patient would recover his or her health or would die. He thus became known as the doctor of death.

In his earlier years, he followed the trade of a poor but honest weaver in the town of Deckendorf near Straudigen in Bavaria. It was a time of famine(饑荒), and he, his wife, and their eleven children were in great need. Then a twelfth child was born, and they could find no one to serve as its godparent. As a last chance, the poor weaver walked to a nearby village and asked an old friend to serve as godfather, but met only rejection. Disappointed and frustrated, the poor man made his way back to his family. While walking sorrowfully through the dense forest toward his home, he said, “If only I could die.” Suddenly a tall figure dressed in a dark cloak(斗篷) appeared before him, saying, “You called me. I am Death. What can I do for you?” As much as the man had previously wanted to die, he now wanted to live. “I am seeking a godfather for my youngest child. But I cannot find anyone who will serve as his godparent,” answered the weaver sadly. “I will accept this responsibility,” said Death. And thus it happened.

Following the baptism(洗禮), the mysterious godfather took the father aside and said, “Since I own neither gold nor silver to give to your child as a baptism present, I will make you into the most famous doctor of all times. Whenever you are called to a sick person, I—invisible to others—will seat myself either to the head or to the feet of the patient. If I am seated at the head, then this will show you that hope for recovery exists. If I am seated at the feet, then the patient will die.” Through this gift, the weaver was able to cure many illnesses, for he knew whether the patient who had sought his treatment would be helped by medications, or whether he would die. Soon the previously poor weaver became a wealthy and respected physician. However, his increased wealth made him ever-more greedy.

One day, a very wealthy man fell seriously ill, but when Dr. Urssenbeck was called in, and he saw that Death was already seated at the patient’s feet. Upon hearing the diagnosis, the relatives could not be comforted, and they offered the physician a fortune if he could heal the man. Then Urssenbeck resorted to trickery. He quickly had the patient’s bed turned around, so that Death was now seated at his head. Thus the man was rescued from Death, and he regained his health. On the physician’s way home, Death suddenly appeared before him. “You unfortunate one, why have you deceived me? In return for the life that you have given back to the rich man, you yourself must now die.” Death spoke with a threatening voice, and disappeared.

Dr. Urssenbeck suddenly found himself in a large room where thousands of candles were burning. Death said to him, “Each of these candles represents someone’s life. This tiny stump that is about to go out is yours.” Terrified, Dr. Urssenbeck reached for a taller candle, wanting to take some wax(蠟) from it to fill his stump, but in doing so he touched his own candle, and it went out, and he fell to the floor dead. That evening his body was found in a valley. He was buried in the graveyard of Saint Stephen’s Cathedral.

1.Why did Death make the weaver a famous doctor?

A. Because he wanted to play a trick on him.

B. Because he didn’t have any baptism gift for his child.

C. Because he wanted to give him something as a reward.

D. Because he wanted to show his sympathy to the weaver.
