【正文】 can unilaterally(單方面地 ) violate agreements that we have all signed up to. So perhaps the fouryearold?s intuitions(直覺 ) about fairness is the beginnings of an understanding of negotiation. With a sense of fairness, people will have to make us acceptable offers (or we?ll reject their ultimatums) and stick by the (reasonable) rules, or we?ll be on the warpath. So a sense of fairness is crucial to effective negotiation。 the bear one. “Is that fair?” asks the experimenter. The girl judges that it is not. “How about now?” asks the experimenter, breaking the bear?s single biscuit in half. The girl cheers up: “Oh yes, now it?s fair. They both have two.” Strangely, children feel very strongly about fairness, even when they hardly understand it. Adults care about fairness too but how much? One way to find out is by using the ultimatum (最后通牒 ) game, created by economist Werner Guth. Jack is given a pile of money and proposes how it should be divided with Jill. Jill can accept Jack?s “ultimatum”, otherwise the deal is off, and neither gets anything. Suppose Jack and Jill don?t care about fairness, just about accumulating cash. Then Jack can offer Jill as little as he likes and Jill will still accept. After all, a little money is more than no money. But imagine, instead, that Jack and Jill both care only about fairness and that the fairest oute is equality. Then Jack would offer Jill half the money。s constantly washing their hands. I?m not saying that it is an obsession, but I?m saying that it could turn into one, very easily, Rosen says. While 9 out of 10 participants in the study of college students said the vibration feeling bothered them only a little or not at all, Rosen still remends backing away from our phones every once in a while to keep our anxiety levels down. “One of the things I?m really adamant about in spite of being very protechnology, is just away from the technology for short periods, Rosen says． And by short periods． I mean, maybe just 30 minutes or an hour.” 62. According to the article, phantom vibrations_____． A. are mainly caused by neurons firing B. affect people mostly working on farms C. help our brains better process information D. started troubling people in recent years 63. The underlined word adamant in the last paragraph probably means_____. A. curious B. determined C. satisfied D. cautious 64. It can be concluded from Larry Rosen39。s an example of how our devices are changing how our brains process information． “We?re seeing a lot of what looks like obsessive behavior. People who are constantly picking up their phone look like they have an obsession. They don39。d asked me 10 years ago, or maybe even five years ago if I felt an itch beneath where my pocket of my jeans was, and asked me what I would do, I39。s very similar to what my phone sounds like when it vibrates on my desk or in my purse.” Other people may not confuse cows for their phones, but research shows phantom vibration symptom is a nearuniversal experience for people with smartphones Nearly 90 percent of college undergraduates in a 2021 study said they felt phantom vibrations. The number was just as high for a survey of hospital workers, who reported feeling phantom vibrations on either a weekly or monthly basis． “ Something in your brain is being triggered（觸發(fā)） that39。 A Homonym: a word that has the same spelling and the same pronunciation as another world, but a different meaning Same spelling, different meaning Imagine, then a situation where two words are spelt and pronounced exactly the same way, but have pletely different meanings. Wele to the world of homonyms. Take, for example, the word ?fail? it can be a kind of festival, and adjective to describe the color of your hair or how you should play a game. Don’t take it literally So how do you know which meaning someone is referring to? You don?t, except by the context. Obviously, if someone asks you to ?give them a hand?, they don?t want you to remove what is at the end of your arm. What’s in a name? Sometimes even the context doesn?t help much the result can be amusing. These sentences play with the double meaning of a noun: I used to be a banker, but I lost interest. Have you heard about the crosseyed teacher who couldn’t control his pupils? A small boy swallowed some coins and had to go to hospital. When his grandmother phoned to ask how he was, the nurse said: ‘No change yet’. More ambiguity And these examples play with the different meanings of a verb: I wondered why the ball was getting bigger. Then it hit me. No one knew she had a dental implant until it came out in a conversation. A boiled egg in the morning is hard to beat. Double trouble And sometimes a word can be a noun and a verb, but have different meanings. Can you work this one out? Time flies like an arrow. Fruit flies like a banana. If you like these homonyms, you will be pleased to know that English has plenty more! Explanations of jokes in the text I used to be banker, but I lost interest. (I became bored with the job / I lost money) Have you heard about the crosseyed teacher who couldn’t control his pupils? (students / parts of his eyes) A small boy swallowed some coins and had to go to hospital. When his grandmother phoned to ask how he was, the nurse said: ‘No change yet’. (no difference in the situation / no money) I wondered why the ball was getting bigger. Then it hit me. (the ball hit me / I suddenly realized) No one knew she had a dental implant until it came out in a conversation. (became known / fell out) A boiled egg in the morning is hard to beat.
