听力原文: Today I’ m going to talk about a very special kind of person. Psychologists call them “ masters of deception” , tho rare individuals with a natural ability to tell with complete confidence when someone is telling a lie. [16] For decades, rearchers and law enforcement agencies have tried to build a machine that will do the same thing. Now, a company in Massachutts says that by using magnetic brain scans, they can determine with 97% accuracy whether someone is telling the truth. They hope that the technology will be cleared for u in American courts by early next year. But is this really the ultimate tool for you, the lawyers of tomorrow? [17] You will not find many brain scientists celebrating this breakthrough. The company might be very optimistic, but the ability of their machine to detect deception has not provided credible proof. That’ s becau the technology has not been properly tested in real world situations. In life, there are different kinds of lies and diver contexts in which they’ re told. The differences may elicit differen
蜡笔英语怎么读crayont brain respons. Does their hypothesis behind the test apply in every ca? We don’t know the answer, becau studies done on how reliable this machine is have not yet been duplicated. Much more rearch is badly needed. Whether the technology is eventually deemed reliable enough for the courts will ultimately be decided by the judges. Let’ s hope they’ re wi enough not to be fooled by a machine that claims to determine truthfulness at the flip of a switch. They should also be sceptical of the growing tendency to try to reduce all human traits and actions to the level of brain activity. Often, they do not map that easily. Moreover, understanding the brain is not the same as understanding the mind. Some rearchers have suggested that thoughts cannot properly be en as purely internal. Instead, thoughts make n only in reference to the individuals’ external world. So while there may be insights to be gained from matching behavior to brain activity, tho insights will not necessarily lead to justice in a court of law. Problems surround the u of machines to spot deception, at least until it has been rigorously tested. [18] A high-tech test that can tell when a person is not telling the truth sounds too good to be true. And when something sounds too good to be true, it usually is.
Questions 16 to 18 are bad on the recording you have just heard.16. What have rearchers and law enforcement agencies tried to do?17. How do many brain scientists respond to the Massachutts company ‘ s so-called technological breakthrough?18. What does the speaker think of using a high-tech test to determine whether a person is telling the truth?

头皮屑大块听力原文: Last week, I attended a rearch workshop on an island in the South Pacific. Thirty people were prent, and all except me came from the island, called Maklua, in the nation of Vanuatu. They live in 16 different communities and speak 16 distinct languages. In many cas, you could stand at the edge of one village and e the outskirts of the next community. [19] Yet the residents of each village speak a completely different language. According to recent work by my colleagues at the Max Plank Institute for the Science of Human History, this island, just 100 kilometers long and 20 kilometers wide, is home to speakers of perhaps 40 different indigenous languages. Why so many? We could ask the same question of the entire globe. People don’ t speak one universal language, or even a handful. [20] Instead, today our species collectively speaks over 7,000 distinct languages. And the languages are not spread randomly across the planet. For example, far more languages are found in tropical regions than in the mild zones. The tropical island of New Guinea is home to over 900 languages. Russia, twenty times larger, has 105 indigenous languages. Even within the tropics, language diversity varies widely. For example, the 250,000 people who live on Va
nuatu’s 80 islands speak 110 different languages. But in Bangladesh, a population 600 times greater speaks only 41 languages. How come humans speak so many languages? And why are they so unevenly spread across the planet? As it turns out, we have few clear answers to the fundamental questions about how humanity communicates. Most people can easily brainstorm possible answers to the intriguing questions. They hypothesized that language diversity must be about history, cultural differences, mountains or oceans dividing populations. But when our diver team of rearchers from six different disciplines and eight different countries began to review what was known, we were shocked that only a dozen previous studies had been done:, including one we ourlves completed on language diversity in the Pacific. [21] The prior efforts all examine the degree to which different environmental, social, and geographic variables correlated with a number of languages found in a given location. The results varied a lot from one study to another, and no clear patterns emerged. The studies also ran up against many methodological challenges, the biggest of which centered on the old statistical saying “correlation does not equal causation”. Questions 19

听力原文: We often hear people say that America is a land of opportunity, a country built on hope to aspire to greatness on the American dream. But as the dream as we once knew is dying, [22] today’ s demographics show that the middle class is disappearing. And now the richest one percent of the population has amasd more wealth than the bottom ninety percent. [23] Once upon a time, Americans thought that if they worked hard enough, even in the face of adversity, they would be rewarded with success. The days, though, the divide between rich and poor is greater than it has ever been. The question is, what is it going to take to change things? Maybe one day soon, real change will actually be made in our nation, and the gap will be eradicated. But what happens in the meantime? Is there something that we can do to help clo the gap? Is there something that we can do to prove that a little compassion goes a long way? If we want to fix the problem of the income gap, first, we have to understand it. It is a grim reality that you can have one person who only makes around thirteen thousand dollars a year, while across town another is making millions. For me, it is kind of astonishing. [24] A
mouldednd if you ask low-income people whatbra是啥意思呀’ s the one thing that would change their life, they’ll say a full-time job. That’ s all they aspire to. So why is it so difficult for so many people to find employment? It partly comes down to profit-driven business models that are built around low wage work and part-time jobs that don’ t provide benefits. [25] Business, in order to bolster profits, hire employees as part-time workers only. This means they are paid the lowest legal wage and receive no health care or other benefits provided to full-time employees. Simultaneously, technological advancement and a global economy has reduced the demand for well paying blue collar jobs here in the United States. The cumulative effect of the two factors is that many Americans are forced to take two or more part- time jobs just to make ends meet. What has become obvious to me when it comes to the income gap is that there needs to be an opportunity for the people at the bottom to push them back up and push them into the middle class to give them hope in their lives.Questions 22 to 25 are bad on the recording you have just heard. 22. What do the surveys show about America, according to the speaker?23. What did Americans u to believe?24. What do low-income people aspire to?25. What do business do to increa their revenues?
