单选题Impatience has been around for a long time. There is nothing new about people losing their patience while stuck in traffic or waiting in line. But some experts believe that people are less patient today than in the past. Some analysts suggest that in recent years many people are less patient because of technology. They suggest that "digital technology, from cellphones to e-mails to iPads, is changing our lives. The instant results we get from this technology have in turn increased our appetite for instant satisfaction in other aspects of our lives." Psychologist Jennifer Hartstein makes some observations. She explains that "we have become an immediate satisfaction culture, and we expect things to move quickly, efficiently and in the way we want. When that doesn"t happen, we tend to become increasingly frustrated and unsatisfied." Some believe that e-mail is losing popularity and could soon become outdated. Why? Because many people who send messages do not have the patience to wait hours, or even minutes, for a response. Also, with e-mails, as with letter writing, introductory and concluding greetings are often expected. But many people consider such formalities (客套) to be boring and time-consuming. They prefer instant messaging. Many people do not take the time to proofread what they put in writing. As a result, letters and e-mails contain numerous grammatical and typographical errors. The thirst for immediate results is not limited to the realm of digital communications. People seem to be losing their ability to wait in other areas of life. For instance, do you ever find yourself talking too fast, eating too fast, driving too fast, or spending money too fast? The few moments it takes to wait for an elevator to come, for a traffic light to change, or for a computer to start may seem like too long a time.

单选题Sports and games make our bodies strong, prevent us from getting too fat, and keep us healthy. But these are not their only use. They give us valuable practice in making eyes, brain and muscles work together. In tennis, our eyes see the ball coming, judge its speed and direction and pass this information on to the brain~ The brain then has to decide what to do, and to send its orders to the muscles of the arms, legs, and so on, so that the ball is met and hit back where it ought to go. All this must happen with very great speed, and only those who have had a lot of practice at tennis can carry out this complicated chain of events successfully. For those who work with their brains most of the day, the practice of such skills is especially useful. Sports and games are also very useful for character-training. In their lessons at school, boys and girls may learn about such virtues as unselfishness, courage, discipline and love of one's country; but what is learned in books cannot have the same deep effect on a child's character as what is learned by experience~ The ordinary day-school cannot give much practical training in living, because most of the pupils' time is spent in classrooms, studying lessons. So it is what the pupils do in their spare time that really prepares them to take their place in society as citizens when they grow up. (16) If each of them learns to work for his team and not for himself on the football field, he will later find it natural to work for the good of his country instead of only for his own benefit.

单选题When Mr. Black retired, his son ______ the business.

单选题Not all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares (噩梦). Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly erase (抹去), the effect of painful memories. In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased. The research has caused a great deal of argument. Some think it is a bad idea, while others support it. Supporters say it could lead to pills that prevent or treat soldiers" troubling memories after war. They say that there are many people who suffer from terrible memories. "Some memories can rain people"s lives. They come back to you when you don"t want to have them in a daydream or nightmare. They usually come with very painful emotions." said Roger Pitman, a professor of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering." But those who are against the research say that it is very dangerous to change memories because memories give us our identity (物质). They also help us all avoid the mistakes of the past. "All of us can think of bad events in our lives that were horrible at the time but make us who we are. I"m not sure we want to wipe those memories out," said Rebecca Dresser, a medical ethicist.
