    According to the passage, the computer technology can . A. get rid of the need for frost protection B. help the farmer get a better harvest C. tell the farmer why outdoor temperature changes D. prevent the temperature from dropping to the freezing point (D) Have you ever been in a meeting while someone was making a speech and realized suddenly that your mind was a million miles away?You probably felt sorry and made up your mind to pay attention and never have daydreaming again. Most of us, from earliest school days, have been told that daydreaming is a waste of time. "On the contrary, "says L. Giambra, an expert in psychology, "daydreaming is quite necessary. Without it, the mind couldn't get done all the thinking it has to do during a normal day... You can't possibly do all your thinking with a consciousmind. Instead, your unconscious mind is working out problems all the time. Daydreaming then may be one way that the unconscious and conscious states of mind have silent dialogues. " Early experts in psychology paid no attention to the imporance of daydreams or even considered them harmful. At one time daydreaming was thought to be a cause of some mental illnesses. They did not have a better understanding of daydreams until the late 1980s. Eric Klinger, a professor of psychology, is the writer of the book Daydreaming. Klinger says, "We know now that daydreaming is one of the main ways that we organize our lives, learn from our experiences, and plan for our futures...Day dreams really are a window on the things we fear and the things we long for in life. " Daydreams are usually very simple and direct, quite unlike sleep dreams, which may be hard to understand. It's easier to gain a deep understanding of your life by paying close attention to your daydreams than by trying to examine your sleep dreams carefully. Daydreams help you recognize the difficult situations in your life and find out a possible way of handlingthem. Daydreams cannot be predicted;they move off in unexpected directions which may be creative and full of useful ideas. For many famous artists and scientists, daydreams were and are a main source of creative energy. So the next time you catch yourself daydreaming, don't stop. Just pay attention to your dream. It may be more important than you think. 【查看更多】

     

    题目列表(包括答案和解析)

    Farmer Ed Rawlings smiles as he looks at his orange trees. The young oranges are growing well in Florida's weather. Warm sunshine and gentle rains, along with Ed Rawlings' expert care, will produce a good crop of oranges this year.
    But Ed has to fight against Florida's changeable winter weather. In January and February, temperatures can destroy Ed's entire orange, crop. Having farmed in Florida for the past 35 years, Ed Rawlings is prepared for the frosts(霜). When temperatures drop below freezing， Ed tries to save his crop by watering his orange trees. The water freezes and forms a thin layer (层)of ice on the trees. Strange as it may sound, this thin layer of ice actually keeps the fruit warm.
    What happens is simple. When the trees are watered, the water loses heat and becomes ice. The warmth of the heat it loses is sucked in by the fruit and keeps its temperature at a safe level. Ed Rawlings has effectively used this method(方法)to save many orange crops.
    But Ed still faces some difficulties. The trees should be watered at the exact moment the temperature drops to the freezing point. Also, just the right quantity of water must be used. Too much water can form a thick layer of ice that will break the trees' branches. Another difficulty is that wind blows away the heat. So Ed has to worry about not only when but also how often his trees should be watered, and how much water should be used.
    Computer technology may help Ed Rawlings with some of these worries. With equipment, air and soil temperatures and wind speed can be measured. The information is fed into a computer which can tell when temperatures drop to freezing. The computer can correctly decide the quantity of water to be used and how frequently the trees should be watered. Ed Rawlings will find looking after his orange trees a lot easier with the help of a computer, and we'll all have the benefits(or advantages)of computer-age oranges.

    　　Your home in 2007 will have fewer wires, cleaner air, and a group of fun products to keep you healthy, informed, and entertained．In its latest technology forecast, Battelle has announced what it expects will be the 6 most important technological breakthroughs in household products over the next few years．

    　　1．Disappearing Cords and Cables Wires will begin to disappear from view in homes as we move toward wireless communication, data transmission and energy distribution．That mean more cordless telephones, wireless connectors to the Internet, and even electric lamps and small appliances that don’t have to be plugged in．These energy-saving products include roofing boards that serve as solar-collectors, reducing the need for electricity transferred by wires to homes．

    　　2．Home Waste Management Imagine an in-home system that sorts, recycles and deals with home waste－getting rid of the need for hand sorting．We may even see the development of systems for at-home ?water? treatment and recycling．

    　　3．Highly Miniaturized Communication and Electronic Products In a few years, we will have developed wristwatch-size phones and highly specialized, hand-held, wireless computers that will help us perform a variety of day-to-day activities, from managing your banking and investments to planning your weekend entertainment．

    　　4．Virtual Reality Products Virtual projections and sound environments will be used to increase computer games, music systems, video entertainment systems, and exercise equipment．We will see a convergence(汇聚点)of home entertainment, information, and exercise．

    　　5．Electronic Commerce We will enjoy electronic shopping and banking, including financial transactions(金融交易)that are error-free, safe, easy to use, and low cost．
