The human body has developed its millions of nerves to be highly aware of what goes on both inside and outside of it. This helps us aajust to the outside world. Without our nerves and our brain, which is a system of nerves, we couldn’t know what’s happening. But we pay for our sensitivity. We can feel pain when the slightest thing is wrong with any part of our body. The history of torture is based on the human body being open to pain. But there is a way to handle pain. Look at the Indian fakir (苦行僧) who sits on a bed of nails. Fakirs can put a needle right through an arm, and feel no pain. This ability that some humans have developed to handle pain should give us ideas about how the mind can deal with pain. The big thing in withstanding pain is our attitude toward it. If the dentist says, “This will hurts a little,” it helps us to accept the pain. By staying relaxed, and by treating the pain as an interesting sensation, we can handle the pain without falling apart. After all, although pain is an unpleasant sensation, it is still a sensafion, and sensations are the stuff of life.

A moment's drilling by the dentist may make us nervous and upset. Many of us cannot stand pain.To avoid the pain of a drilling that may last perhaps a minute or two, we demand the "needle"— a shot of novocaine (奴佛卡因) -that deadens the nerves around the tooth.Now it' s true that the human body has developed its millions of nerves to be highly aware of what goes on both inside and outside of it. This helps us adjust to the world. Without our nerves—and our brain, which is a bundle of nerves— we wouldn't know what's happening. But we pay for our sensitivity. We can feel pain when the slightest thing is wrong with any part of our body. The history of torture is based on the human body being open to pain.But there is a way to handle pain. Look at the Indian fakir(行僧) who sits on a bed of nails. Fakirs can put a needle right through an arm, and feel no pain; This ability that some humans have developed to handle pain should give us ideas about how the mind can deal with pain.The big thing in withstanding pain is our attitude toward it. If the dentist says, "This will hurt a little, it helps us to accept the pain. By staying relaxed,' and by treating the pain as an interesting sensation, we' can handle the pain without falling apart.

Many experts believe that in the new world of artificial intelligence(AI)human beings will still be needed to do the jobs that require higher-order critical,creative,and innovative thinking and the jobs that require high emotional engagement to meet the needs of other human beings.The 1 for many of us is that we do not excel at those skills because of our natural cognitive and emotional tendencies:We are confirmation-seeking thinkers and ego-affirmation-seeking defensive reasoners.We will need to overcome those tendencies 2 take our thinking,listening,relating,and collaborating skills to a much higher level.This process of 3 begins with changing our definition of what it means to"be smart."4,many of us have achieved success 5 being"smarter"than other people as 6 by grades and test scores,beginning in our early days in school.AI will change that because there is no 7 any human being can outsmart,8,IBM's Watson,at least without augmentation,Smart machines can process,9,and recall information faster and better than we humans.10.AI can pattern-match faster and produce a wider array of alternatives than we can.AI can even learn faster.In an age of smart machines,our old definition of what makes a person smart doesn't 11.What is needed is a new definition of being smart,one that 12 higher levels of human thinking and emotional engagement.The new smart will be determined not by what or how you know 13 by the quality of your thinking,listening,relating,collaborating,and learning.Quantity is 14 by quality.We will spend more time training to be open-minded and learning to update our beliefs in 15 to new data.We will practice 16 after our mistakes,and we will invest more in the skills traditionally 17 with emotional intelligence.The new smart will be about trying to overcome the two big 18 0f critical thinking and team collaboration:our ego and our fears.Doing so will make it easier to perceive reality as it is,rather than as we 19 it to be.In short,we will embrace humility.That is 20 we humans will add value in a world of smart technology.1选?A.controversyB.challengeC.opportunityD.compromise

共用题干第三篇How We Form First ImpressionWe all have first impression of someone、just met.But why? Why do we form an opinion about someone without really knowing anything about him or her aside perhaps from a few remarks or readily observable traits?The answer is related to how your brain allows you to be~of the world.Your brain is so sensitive in picking up facial traits,Even very minor difference in how a person'5 eyes,ears,nose,or mouth are placed in relation to each other makes you see him or her as different.In fact,your brain continuously processes incoming sensory information-the sights and sounds of your world.These incoming signals are compared against a host of "memories"stored in the brain areas called the cortex(皮质)system to determine what these new signals"mean".If you see someone you know and like at school,your brain says"familiar and safe".If you see someone new it says,"new and potentially threatening".Then your brain starts to match features of this stranger with other"known"memories.The height,weight,dress,ethnicity,gestures,and tone of voice are all matched up.The more unfamiliar the characteristics are,the more your brain may say,"This is new.I don ' t like this person ".Or else , " I'm intrigued(好奇的)".Or your brain may perceive a new face but familiar clothes,ethnicity,gestures-like your other friends;so your brain says,"I like this person".But these preliminary"impressions"can be dead wrong.When we stereotype people,we use a less mature form of thinking(not unlike the immature thinking of a very young child)that makes simplistic and categorical impressions of others.Rather than learn about the depth and breadth of people-their history,interestvalues,strengths,and true character-we categorize them as jocks(骗子),peeks(反常的人),or freaks(怪人).However,if we resist initial stereotypical impressions,we have a chance to be aware of what a person is truly like.If we spend time with a person,hear about his or her life,hopes,dreams,and become aware of the person's character,we use a different,more mature style of thinking-and the most complex areas of our cortex,which allow us to be humane。Which of the following statements best expresses the main idea of the passage?A:One's physical appearance can influence our first impression.B:Our first impression is influenced by the sensitivity of our brain.C:Stereotypical impressions can be dead wrong.D:We should adopt mature thinking when getting to know people.

问答题Practice 1  No one knows what time itself is. We cannot see it. We cannot touch it. We cannot hear it. We know it only by the way we mark its passing. For all our success in measuring the tiniest parts of time, time remains one of the great mysteries of the universe.  One way of thinking about time is to imagine a world without time. There could be no movement, because time and movement cannot be separated. A world without time could exist only as long as there were no changes. For time and change are linked. When something changes, you know time has passed.

问答题This is the world out of which grows the hope, for the first time in history, of a society where there will be freedom from want and freedom from fear. Our very anxiety is born of our knowledge of what is now possible for each and for all. The number of people who consult psychiatrists today is not, as is sometimes felt, a symptom of increasing mental ill health, but rather the precursor of a world in which the hope of genuine mental health will be open to everyone, a world in which no individual feels that he needs be hopelessly broken-hearted, a failure, a menace to others or a traitor to himself. But if our anxieties are actually signs of hope, why is there such a voice of discontent abroad in the land? I think this comes perhaps because our anxiety exists with accompanying recognition of the tragedy which will always be inherent in human life, however well we build our world. We may banish hunger, violence and secret police, we cannot—as we have tried to do—banish death itself.
