单选题A field is simply a social system of relations between individuals or institutions who are competing for the same stake. An example of a field may be higher education, colleges, and universities. Habitus is a set of potential dispositions, an internalized set of taken-for-granted rules that govern strategies, and social practices that individuals in some respects carry with them into any field. There is a system of unspoken rules and generally unspeakable rules. They are unspeakable because it is understood that it would be rude or socially punishable to try to talk about those rules. Or, in some cases individuals within a habitus cannot even articulate those arbitrary rules because they are unaware of them. That is, these rules may feel so natural and normalized that they seem as though they are the way things should be and always have been. An example of an unspeakable rule might be that a person should never discuss class privilege, as opposed to hard work, as contributing to the success of an individual when talking about the accomplishments of the middle class within a middle-class field. However, within a working-class field of manual laborers, this may not be a forbidden topic of discussion. Judith Butler outlined a feminist theory of embodied practice in identity formation. She stated that our sense of identities is formed through repeated daily and everyday constrained and emancipatory performative practices through our bodies. Through the process of repeated performances, ways of being in the world become sedimented, that is layered and accumulated to the extent that these practices become a part of who we are and how we perceive ourselves to be in the world. Butler's insights about performativity, the body, and identity are particularly informative of working-class identity formations that are literally embodied within the physical capacity to do manual labor. Butler's notion of performative identity gives me insight into my own identity development and the discomforts and constraints I have felt within academia, where the mind is privileged over the body in ways that almost obliterate the body. At the same time, the ideology of mind over body seems hypocritical when one examines the class distinctions made through the embedded middle-class practices, in short, the habitus, of the majority of university professors. Many first-generation college students in my classes, especially those who are from working-class backgrounds, report shock, dismay, and anger at the level of classism and racism that exists among faculty, whom they assumed to be educated and to value egalitarian principles. Many students express their frustration at not knowing the habitus of the middle class, yet feel its exclusionary, embodied power. They express even more frustration that the middle class also seems unaware of its own unspoken rules and habitus. Though they can start a conversation about race, they don't know how to talk about class in a meaningful way, one that helps their fellow students to understand the naturalized class distinctions within our culture. Class is America's dirty little secret.

单选题The truly incompetent may never know the depths of their own incompetence, a pair of social psychologists said on Thursday. "We found again and again that people who perform poorly relative to their peers tended to think that they did rather well," Justin Kruger, co-author of a study on the subject, said in a telephone interview. Kruger and co-author David Dunning found that when it came to a variety of skills—logical reasoning, grammar, even sense of humor—people who essentially were inept never realized it, while those who had some ability were self-critical. "It had little to do with innate modesty," Kruger said, "but rather with a central paradox: Incompetents lack the basic skills to evaluate their performance realistically. Once they get those skills, they know where they stand，even if that is at the bottom." "Americans and Western Europeans especially had an unrealistically sunny assessment of their own capabilities," Dunning said by telephone in a separate interview, "while Japanese and Koreans tended to give a reasonable assessment of their performance. In certain areas, such as athletic performance, which can be easily quantified, there is less self-delusion, the researchers said. But even in some cases in which the failure should seem obvious, the perpetrator is blithely unaware of the problem." This was especially true in the areas of logical reasoning, where research subjects—students at Cornell University, where the two researchers were based—often rated themselves highly even when they flubbed all questions in a reasoning test. Later, when the students were instructed in logical reasoning, they scored better on a test but rate themselves lower, having learned what constituted competence in this area. Grammar was another area in which objective knowledge was helpful in determining competence, but the more subjective area of humor posed different challenges, the researchers said. Participants were asked to rate how funny certain jokes were, and compare their responses with what an expert panel of comedians thought. On average, participants overestimated their sense of humor by about 16 percentage points. This might be thought of as the "above-average effect", the notion that most Americans would rate themselves as above average, a statistical impossibility. The researchers also conducted pilot studies of doctors and gun enthusiasts. The doctors overestimated how well they had performed on a test of medical diagnoses and the gun fanciers thought they knew more than they actually did about gun safety. So who should be trusted: The person who admits incompetence or the one who shows confidence? Neither, according to Dunning. "You can"t take them at their word. You"ve got to take a look at their performance," Dunning added.

单选题In bringing up children, every parent watches eagerly the child's acquisition (学会) of each new skill the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself. Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are sever over times of coming home at night or punctuality for meals. In general, the controls imposed represent the needs of the parents and the values of the community as much as the child's own happiness. As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality (道德). Also, parents should realize that "example is better than precept". If they are not sincere and do not practise what they preach (说教), their children may grow confused, and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled. A sudden awareness of a marked difference between their parents' principles and their morals can be a dangerous disappointment.
