单选题 It is foolish to dream of reversing (倒转) history. We cannot pass laws forbidding science and technology. The computing machines are here, and they will not merely stay; they will grow bigger, faster, and more useful every year. They will grow because engineers want to build them, scientists want to use them, industrialists want to employ them, soldiers want to enlist them in new weapons systems, politicians want their help in the processes of government. In short, they will flourish because they enable us to accomplish tasks that could never before have been undertaken, no matter how many unskilled laborers we might have set to work. Computers will continue to amplify our intelligence for just the same reason that engines continue to {{U}}amplify{{/U}} our muscles. The question we must ask is not whether we shall have computers or not have computers, but rather, since we are going to have them, how can we make the most humane (人道的) and intelligent use of them?

单选题Most of the animals have little connection with animals of a different kind, unless they hunt them for food. Sometimes, however, two kinds of animals come together in a partnership which is good for both of them. You may see some birds sitting on the backs of sheep. This is not because they want a ride, but because they find easy food in the parasites(寄生虫)on sheep. The sheep allow the birds to do so because they move the cause of discomfort. So although they can live without each other, they do better together. Sometimes an animal has a plant partner. The relationship develops until the two partners cannot live without each other. This is so in the corals(珊瑚) of the sea. In their skins there are tiny plants which act as "dustmen", taking some of the waste products from the corals and giving in return oxygen(氧气) which the animal needs to breathe. If the plants are killed, or are even prevented from receiving light so that they cannot live normally, the corals will die.

单选题The research was done by a Dr. Griffiths in England. He compared the behavior of 15 regular gamblers with that of 15 non-regular gamblers before and after they gambled. Both groups had increased heart rates during gambling because it was exciting. But the regular gamblers' heart rates went down almost straight after the game. while the non-regulars remained excited and had increased heart rates for longer. When the heart beat increases, the body produces chemicals called endorphins which make you feel good. Dr. Griffiths thinks that regular gamblers lose this good feeling soon after a game and need to play again quickly to regain the pleasure. He has also discovered that regular gamblers have different psychological reactions from those of non-regular gamblers. In an experiment where regular and non-regular gamblers thought aloud while playing, regular gamblers had far more unreasonable thoughts. In their minds they turned losses into near-wins, Dr. Griffiths thinks that nearly winning gives the gambler a high in the way that a win would do. Based on Dr. Griffiths' research, doctors suggest that one way to help regular gamblers to give up gambling is to give them beta-blockers drugs that stop them getting a high in the first place.

单选题{{B}}D{{/B}} There are three kinds of memory: sense memory, working memory, and long-term memory. Think of them as three connected rooms in which you store different kinds of memories. The first kind of memory is sense memory. Everything you are sensing right now is stored here. Perhaps you feel the sun on your face or smell the aroma(香味) of food. Sense memories last only a few seconds, but they connect one moment to the next. They give your life a flow, even though they are quickly forgotten. You keep a few items(条目) in working memory. These are memories you need for what you are doing. Suppose you look up a friend's telephone number in the phone book. You'll probably remember the number for a little while. But if you get distracted (分神), you might quickly forget it. A memory usually stays in your working memory for just a few days at most. Working memory has another limit, too. Only a small number of items fit into it at any given time. Memories you want to keep for a long time go into your long-term memory. They can stay with you all your life. In long-term memory, you can store a huge number of items. Can you re member how to play your favorite game? Do you recall your first birthday party? If so, you are bringing up memories that are stored in your long-term memory. Sometimes, people have trouble finding a particular long-term memory. Have you ever struggled to remember a familiar name or fact? When this happens, people sometimes say the information is "{{U}}on the tip of the tongue{{/U}}. "
