Psycholinguistics is a field at the intersection (交叉) of psychology and linguistics, and one if its recent discoveries is that the languages we speak influence our eye movements. For example, English speakers who hear candle often look at a candy because the two words share their first syllable. Research with speakers of different languages revealed that bilingual speakers not only look at words that share sounds in one language but also at words that share sounds across their two languages. When Russian-English bilinguals hear the English word marker, they also look at a stamp, because the Russian word for stamp is marka.
Even more surprising, speakers of different languages differ in their patterns of eye movements when no language is used at all. In a simple visual search task in which people had to find a previously seen object among other objects, their eyes moved differently depending on what languages they knew. For example, when looking for a clock, English speakers also looked at a cloud. Spanish speakers, on the other hand, when looking for the same clock, looked at a present, because the Spanish names for clock and present—reloj and regalo—overlap at their onset (开始) .
The story doesn't end there. Not only do the words we hear activate other, similar-sounding words—and not only do we look at objects whose names share sounds or letters even when no language is heard—but the translations of those names in other languages become activated as well in speakers of more than one language. For example when Spanish-English bilinguals hear the word duck in English, they also look at a shovel, because the translations of duck and shovel—pato and pala, respectively—overlap in Spanish.
Because of the way our brain organizes and processes linguistic and nonlinguistic information, a single word can set off a domino effect (多米诺效应) that cascades (像洪水般倾泻) throughout the cognitive system. And this interactivity and co-activation is not limited to spoken languages. Bilinguals of spoken and signed languages show co-activation as well. For example, bilinguals who know American Sign Language and English look at cheese when they hear the English word paper because cheese and paper share three of the four sign components in ASL (hand shape, location and orientation but not motion).
What do findings like these tell us? Not only is the language system thoroughly interactive with a high degree of co-activation across words and concepts, but it also impacts our processing in other areas such as vision, attention and cognitive control. As we go about our everyday lives, how our eyes move, what we look at and what we pay attention to are influenced in direct and measurable ways by the languages we speak.
The implications of these findings for applied settings range from consumer behavior (what we look at in a store) to the military (visual search in complex scenes) and art (what our eyes are drawn to). In other words, it is safe to say that the language you speak influences how you see the world not only figuratively (比喻地) but also quite literally, down to the mechanics of your eye movements.
1.What can we learn from Paragraph 3?
A.Languages we know determine our eye movements.
B.The words we hear remind us of similar words.
C.We look at objects even if no language is heard.
D.Translations of words in other languages can be activated.
2.According to Paragraph 4, the ''domino effect'' is caused by ________.
A.American Sign Language B.brain processes
C.oral languages D.co-activation
3.What can we learn from these findings?
A.Words are closely related to concepts in language system.
B.The combination of words and concepts activates language system.
C.The language we speak influences what we pay attention to.
D.What we speak in everyday lives controls how our eyes move.

Like most robots, social robots use artificial intelligence to decide how to act on information received through cameras and other sensors. The ability to respond in ways that seem lifelike has been informed by research into such issues as how perceptions (知觉) form, what constitutes social and emotional intelligence, and how people can infer others’ thoughts and feelings. Advances in Al have enabled designers to translate such psychological and neuroscientific insights into algorithms that allow robots to recognize voices, feces and emotions; interpret speech and gestures; respond appropriately to complex verbal and nonverbal cues; make eye contact; speak conversationally; and adapt to people’s needs by learning from feedback, rewards and criticisms.
A 47-inch humanoid (类人物) called Pepper (from SoftBank Robotics) recognizes faces and basic human emotions and engages in conversations via a touch screen in its “chest,” About 15,000 Peppers worldwide perform such services as hotel check-ins, airport customer service, shopping assistance and fast-food checkout. Temi (from Temi USA) and Loomo (Segway Robotics) are the next generation of personal assistants—like Amazon Echo and Google Home but mobile, providing a new level of functionality. Loomo, for instance, is not only a companion but can also transform on command into a scooter (小型摩托车) for transport.
Social robots have particular appeal for assisting the world’s growing elderly population. The PARO Therapeutic Robot (developed by Japan’s National Institute of Advanced Industrial Science and Technology), which looks like a seal, soft and cute, is meant to stimulate and reduce stress for those with Alzheimer’s disease and other patients in care facilities: it responds to its name by moving its head, and it cries for petting. Mabu (Catalia Health) engages patients, particularly the elderly, as a wellness aide, reminding them to take walks and medication and to call family members. Social robots are also gaining popularity with consumers as toys. Early attempts to include social behavior in toys, such as Hasbro’s Baby Alive and Sony’s AIBO robotic dog, had limited success. But both arc resurging (复活), and the most recent version of AIBO has advanced voice and gesture recognition, can be taught tricks and develops new behaviors based on previous interactions.
Worldwide sales of consumer robots reached an estimated $5.6 billion in 2018, and the market is expected to grow to $19 billion by the end of 2025, with more than 65 million robots sold a year. This trend may seem surprising given that multiple well-funded consumer robot companies, such as Jibo and Anki, have failed. But a wave of robots is lining up to take the place of old robots, including BUDDY (Blue Frog Robotics), a big-eyed mobile device that plays games in addition to acting as a personal assistant and providing home automation and security.
1.What does the first paragraph mainly talk about?
A.How social robots receive information.
B.What research has been conducted about social robots.
C.Why social robots can respond in lifelike ways.
D.How designers translate insights into social robots.
2.Examples are used in Paragraph 2 to show that social robots are ________.

C.interacting with people D.learning to respond in lifelike ways
3.According to the passage we know that ________.
A.social robots can have various forms and appearances
B.PARO can interact with people by moving its head like a dog
C.the most recent version of AIBO has achieved as great success as before
D.the sales of consumer robots have been increasing as ever expected
4.What is the best title for the passage?
A.More companies will invest on social robots.
B.Social robots play nicely with human beings.

My younger daughter, age 5, made a failed attempt during a recent school-night bedtime routine. In retaliation (报复) for my insistence that she actually stay in bed, she uttered the classic pint-sized revolutionary cry: ''You're not in charge of me! ''
''I am, actually, '' I replied as I gently guided her back into bed. ''I am in charge of keeping you safe and also helping you thrive (茁壮成长), which means making sure you get a good night's sleep and a whole lot more. ''
I knew what I meant by ''more'' even if she didn't. I made a personal, unwritten covenant (契约) with my daughters, and even society, to do my part to raise two happy, virtuous, inspirational adults. And that requires teaching a good deal of life wisdom, role modeling and, at times, imposing behavior.
We are the boss. We can also be our kids' friend, sometimes. And we are always their teacher and coach. And don't forget lifeguard.
But we're in charge, even if we don't want to be. And it seems a lot of parents don't want to be.
I've noticed that for various reasons (trying to be cool/nice/laid back, maybe laziness, maybe in opposition to being raised with too many rules themselves) , many parents let their children call too many shots. I'm talking about screen time, bedtime, purchases, meal options and all the rest of it.
Letting kids decide these matters usually leads to poor outcomes for the kids themselves. A permissive parenting style leads to impulsive behavior, egocentrism (唯我主义) and poor social skills, according to Diana Baumrind, a developmental psychologist at the University of California, Berkeley.
Baumrind, one of the leading researchers on this topic, described the ideal parenting style as ''authoritative, '' neither too permissive nor too controlling. An authoritative parent has clear rules and high expectations while being warm and supportive and valuing in dependence. If we can do that for our children, her research showed, they will have greater self-esteem, social skills and academic performance.
The ideal, in other words, is a Buddhist Middle Way where we are in control but foster (培养) independence.
But independence is not the same as giving them what their little id (本我) brains want all the time. Children may seem happy about getting their way, but it's actually an insecure world for them to inhabit where adults don't seem fully in charge.
Young kids' brains are not up to the task of making the best decisions anyway. From age 2 until 7, according to the pioneering child developmental psychologist Jean Piaget, a child naturally engages in egocentrism and ''magical thinking''—believing that they can affect the world with their thoughts—but not critical thinking. From about age 8 to 11, kids tend to actively seek rules, limits and boundaries―but from parents and teachers, not from themselves; they want adults to draw the lines they can safely color in.
Typically, after age 11, critical thinking emerges. Real involvement in rules and limits can effectively begin then, but even teenagers need the assurance that you will always steer them in the right directions.
We also know that real life is full of rules—legal, societal, ethical (moral) or just politeness—and either we teach them or they will eventually be set straight in less-loving environments such as the playground, the principal's office, in front of a judge or in a professional boss’ office.
And being in charge doesn't mean we need to micromanage behavior or be unkind. We should build in plenty of personal freedom and remain motivated by deep love and affection. But we must also be on top it, guiding them toward success.
Be a great boss to your kids. Mentor them. Give them opportunities to develop and shine. Always have their backs. Never fire them. Show them who's boss in the most caring of ways.
