Technology is the application of knowledge to production. Thanks to modern technology, we have been able to increase greatly the efficiency of our work force. New machines and new methods have helped cut down time and expense while increasing overall output. This has meant more production and a higher standard of living. For most of us in America, modern technology is thought of as the reason why we can have cars and television sets. However, technology has also increased the amount of food available to us, by means of modern farming machinery and animal breeding techniques, and has made our life span longer via medical technology.

    Will mankind continue to live longer and have a higher quality of life? In large measure, the answer depends on technology and our ability to use it widely. If we keep making progress as we have over the past fifty years, the answer is definitely yes. The advancement of technology depends on research and development, and the latest surveys show that the united States is continuing to put billions of dollars annually(每年) into such efforts. So while we are running out of some limited resources, we may well find technological substitutes (代用品) for many of them through our research programs.

    Therefore, in the final analysis, the three major factors of production (land, labor and capital) are all influenced by technology. When we need new skills or techniques in medicine, people will start developing new technology to meet those needs. As equipment proves to be slow or inefficient, new machines will be invented. Technology responds to our needs in helping us improve our standard of living.

    Once upon a time there were two friends who lived in a palace and worked in the service of the king. One of the two boys knew a girl he liked so much that he wanted to give her a present.

    One day, when he was walking with his friend in the main palace hall, he saw a big vase filled with the most beautiful flowers. He decided to take one to give to the girl, thinking that no one would see him do so except his friend. He did the same thing the next day, and the next, and the next... until, one day, the king noticed how few flowers were left in the vase. He was so angry that he called everyone in the palace to come together in the hall.

    When they were all before the king, the boy thought he should say it was he who had taken the flowers. However, his friend told him to be quiet, because the king would be terribly angry with him. The boy was filled with fear, but when the king came near, he decided to confess.

    As soon as the boy said that he had done it, the king went red with anger, but on hearing what the boy had done with the flowers, a smile appeared on the king's face, and he said, “I couldn't have thought of a better use for my flowers.”

    And from that day, the boy and the king became great friends. They went to the vase and took two of those wonderful flowers, one for the girl, and the other for the queen.

    Two deer jumped out in front of 16-year-old Amanda Floyd's car. She stepped on the brake, stopping the car just in time. But later, she started texting. Distracted (分心的)，Amanda turned left and right, then crashed into another car. Luckily, she wasn't in a real car--she was in a driving simulator (模拟器) at Roosevelt High School, Ohio, US. “I never really realized that cars make a turn that much," Amanda, a Junior, said. She added that she wouldn't text while driving anymore.

    The Ohio Department of Transportation (ODOT) and State Highway Patrol brought the simulator to the school. They said they wanted to help students learn about the danger of driving while drunk, while texting, or while talking on the phone.

According to the National Highway Traffic Safety Administration, distracted driving claimed 3,4501ives in2016 alone. Experts believe the actual figure is probably higher.

The simulator is basically a computer program. Like many computer games, it was a hit with the students. They lined up and crowded around to watch each other take turns. The simulator has a steering wheel! (方向盘) ,brake and gas pedal (油门踏板) . It is made up of three large computer screens on a table.

    Students choose a distraction, such as driving while drunk or texting. They always crash, of course. Then, they are pulled over by the police to be taught the bad results of their driving: how much damage they've caused, what their fine is, if anyone died in the accident, and if they're going to go to prison.

    "It teaches how to drive without being on the road," said Shante Thompson, 16. She had just crashed into a deer.

    ODOT spokesman Justin Chesnic said hundreds of kids have gone behind the wheel so far. He said even more have benefited from watching their classmates. "Driving is such a major responsibility, so take it seriously" he said. “Put away your cellphone. A lot of the accidents out there are because of distracted driving. It can not only change your life, but it can change someone else's life forever. The results are serious."

    Most people feel lonely sometimes, but it usually lasts only between a few minutes and a few hours. This kind of loneliness is not serious. In fact, it is quite normal. For some people, though, loneliness can last for years. Now researchers say there are three different types of loneliness.

    The first kind of loneliness is temporary. This is the most common type. It usually disappears quickly and does not require any special attention. The second kind, situational loneliness, is a natural result of a particular situation－for example, the death of a loved one, or moving to a new place. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year.

    The third kind of loneliness is the most severe. Unlike the second type, chronic(长期的) loneliness usually lasts more than two years and has no specific cause. People who experience habitual loneliness have problem socializing and becoming close to others unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition.

    Many researchers agree that the loneliest people are between the ages 18 and 25, so a group of psychologists decided to study a group of college students. They found that more than 50% of the students were situationally lonely at the beginning of the term as a result of their new circumstances, but had adjusted after a few months, 13% were still lonely after seven months due to shyness and fear. They felt very uncomfortable meeting strangers, even though they understood that their fear was not reasonable. The situationally lonely students overcame their loneliness by making new friends, but the chronically lonely remained unhappy because they were afraid to do so.

    Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness such as heart disease. While temporary and situational loneliness can be a normal, healthy part of life, chronic loneliness can be a very sad, and sometimes dangerous condition.

    The stories we share with one another are important. They show wisdom and provide inspiration. They are important to our development. But sometimes people choose not to tell.

    Consider the negative effects of not sharing a story in the news: People are wondering if public health officials are holding back too much information about the recent outbreak of Ebola.

    There is a danger in holding back stories that ought to be told. Bobette Buster said it like this, "The fact is, history has shown us that stories not told can become like a dangerous genie (妖怪) left in a bottle. When they are finally uncorked, their power to destroy is set free."

    There are a number of reasons why we hide parts of our story: they often show our weaknesses or expose our disadvantages; they require courage and strength to share; and of course, there are some stories that should be kept secret—especially those that embarrass someone else.

    Most of us have two selves: the one we display on the outside and the one we actually are on the inside. And the better we get at hiding the stories that show our true selves, the more damage we may be causing to ourselves and to others.

    Honesty and openness is important: it proves we are trustworthy. It displays we are human. We are not perfect or better. It highlights the importance of hard work and personal development. Hard work may not allow us to overcome our disadvantages completely. But with hard work, we do not have to be restricted to our mistakes.

    Does this mean we admit every weakness, every disadvantage, and every secret regret to everybody we meet? No, of course not. There is a time and a place and a certain level of relationship necessary for some stories to be told in an appropriate manner.
