单选题 Most of us tend to think that attractive people are always at an advantage in life and enjoy far more opportunities than average-looking or unattractive people, especially when it comes to employment. But a new study suggests this perception is actually not the case for all jobs. Beautiful people are less likely to land menial jobs or positions that involve uninteresting work. The study published Tuesday in the Journal of Personality and Social Psychology finds being beautiful is a liability when it comes to seeking out less desirable positions, which is proof that attractive people don't get everything they want. The researchers found people interviewing and hiring for these jobs favor unattractive candidates because they perceived attractive candidates would be dissatisfied with the pay and the work. The findings are based on a series of experiments that involved more than 750 people. They included university students and hiring managers. The researchers showed the hiring managers profiles that included photos of potential candidates (one attractive and one not so much). The researchers asked the hiring managers a series of questions that were meant to assess their perceived attractiveness. They also asked the participants which candidate they were more likely to hire for the low-paying positions that included warehouse worker, customer service representative and housekeeper versus more appealing jobs such as manager, project director and an IT internship (实习生). The researchers found that the hiring managers' decisions were driven by their belief that the nice-looking candidates would be unhappy and unsatisfied with the menial jobs and maybe even less likely to do the work. The researchers were surprised by this, since previous research has shown that attractive people always have an edge with employment, such as a study in which researchers sent 1100 fake resumes to employers to fill advertised vacancies. They found 54 percent of attractive women were contacted while 47 percent of attractive men received calls, according to the Independent. On the other hand, only 7 percent of unattractive women and 26 percent of unattractive men were contacted by potential employers. The authors of the new study suggest their findings should be considered when it comes to creating policies about job discrimination. This conclusion is likely to be laughable to unattractive people who have landed jobs but didn't win the genetic lottery.

单选题 Learning is an essential process for living things to acquire necessary skills and behaviors. Scientists have already found that there is a critical period for learning in man and animals. Once the right time for learning a skill or a certain behaviors has passed, this skill or behavior can never be properly learned. That we speak our own language perfectly and the languages we learn later imperfectly also depends on learning this skill at the right time. The brain develops in such a way that it is ready to learn to speak between the ages of about ten months and ten years. Languages learned later are not spoken perfectly. The ability to speak a language is a mixed motor and sensory skill. It is necessary to hear all the sounds, the subtle differences between similar but not identical sounds, the rhythm and tone of the language. One has also to work tongue, throat, and lips to control breathing. All this has to be managed at one and the same time. From some time after birth until the age of six or seven, normal children all learn this perfectly, and without much difficulty they can learn two or even three languages at the same time, without confusing one with the other. But later, most of us cannot acquire this skill. We may learn to write and read the new language perfectly, but to acquire the right accent and the ability to speak so that no one can detect that the language is not our mother tongue hardly ever occurs. But those of us who still want to learn foreign languages after these early milestones have been passed need not worry, for though we may not learn to speak a new language like the natives, we know from thousands of examples that we can go on learning languages beyond the age of eighty. There are so many activities adding up to the simple word 'learning' that although some of the processes become less efficient with ageing of the brain, our actual experience of learning helps us in learning new materials. Normal social and emotional development probably also needs the correct stimulating at the right time. We can observe evidence of this in those rare cases of children who have been completely neglected from birth. Sometimes illegitimate children in the country are put away in barns to conceal their existence from the neighbors. They are taught nothing, not even to be house-trained or to speak. These children then grow up mentally defective. Even if they are found and rescued by the age of four or five, it is too late. Though they can be taught a lot, their speech is always inadequate and their brains never reach the standards of their brothers or sisters.
