单选题Helen Keller was born a healthy normal child in Alabama in 1880. However, an illness with a high fever struck her when she was still a child. She became deaf, blind, and unable to speak. For little Helen, the world was suddenly a dark and frightening place. She was wild and stubborn. Several years later a miracle came into Helen's life when Anne Sullivan, a strong and loving person, became Helen's teacher. Miss Sullivan's teaching changed the child into a responsible human being. Through her help Helen Keller learned to communicate with those around her, and as she grew older, others benefited from her unique insights and courage. Miss Keller died in 1968, but her spirit lives on. It lives on in her articles and books and in the stories of people who were fortunate enough to meet her during her lifetime.

单选题You would think that people with a history of being discriminated against in the workplace might give those whom they resemble a break. But a growing body of research confirms exactly the opposite: women are just as likely as men to show, sexism toward women in hiring practices, salaries and professional mentorship. Overt displays of sexism are largely passe in the American workplace. What remains, unfortunately, is a set of subtler and more ingrained cognitive biases deeply rooted in our evolutionary and cultural past. Getting rid of them will require an honest reckoning with the inalienable fact that humans are inclined to make implicit errors in perception and even good people who actively avoid bias may nonetheless harbor subtle yet damaging stereotypes of which they are unaware. In one of the latest studies, a psychology experiment published in the Proceedings of the National Academy of Sciences, senior science faculty across the U.S. were presented with identical resumes for a lab-manager job (a position that can often lead to graduate study) that differed only in the gender of the hypothetical applicant. The resume raters were statistically more likely to rate the male candidate higher on competence and hirability and were also more likely to offer the male candidate a bigger salary and greater professional mentorship. By contrast, the hypothetical female applicants were rated more likable but less hirable. Female scientists were just as likely to favor male candidates as potential hires as male scientists were. There are countless examples of bias against women by both sexes in nonscience fields, including, famously, the increase in women who were hired for orchestras when musicians auditioned behind a blind screen. It's hard to imagine why this kind of cognitive bias persists in the 21st century, especially when the achievement gaps between males and females arc closing rapidly. But this only seems puzzling because we tend to think that bias is an evil word, infected with uglyisms and the deliberate diminishing of certain kinds of people. Current research is showing that all human beings have unconscious cognitive biases—what Harvard professor Mahzarin Banaji calls "mind bugs. "These biases may have been adaptive thousands of years ago, when people lived in small, homogeneous communities and in-group favoritism might have made the difference between life and death. But they are problematic in our global 21st century world. The pervasiveness of cognitive bias is depressing. It's more comfortable to think of sexism or racism or ageism as a symptom of a few rotten apples than as a fundamental human trait. But if we're all doing it, even to ourselves ,how on earth can we move beyond the stereotypes? If we want to eliminate the perception that women are less competent than men for certain jobs held by both sexes, it's not enough to hire more women for traditionally male-dominated jobs. A more fundamental problem is that cognitive bias is rooted not only in our primitive past but also in our contemporary culture. We can't be surprised by unconscious stereotypes about women when we still embrace a culture infected with sexism in everything from popular movies to recent congressional debates.

单选题 New technology links the world as never before. Our planet has shrunk. It's a new "global village" where countries are only seconds away by fax or phone or satellite link. And, of course, our ability to benefit from this high-tech communications equipment is greatly enhanced by foreign language skills. Deeply involved with this new technology is a breed of modem businesspeople who have a growing respect for the economic value of doing business abroad. In modem markets, success overseas often helps support domestic business efforts. Overseas assignments are becoming increasingly important to advancement within executive ranks. The executive stationed in another country no longer needs fear being "out of sight and out of mind". He or she can be sure that the overseas effort is central to the company's plan for success, and that promotions often follow or accompany an assignment abroad, if an employee can succeed in a difficult assignment overseas, superiors will have greater confidence in his or her ability to come back in the United States where cross-cultural considerations and foreign language issues are becoming more and prevalent (普遍的) . Thanks to a variety of relatively inexpensive communications devices with business applications, even small businesses in the United States are able to get into international markets. English is still the international language of business. But there is an ever-growing need for people who can speak another language. A second language isn't generally required to get a job in business, but having language skills gives a candidate the edge when other qualifications appear to be equal. The employee posted abroad who speaks the country's principal language has an opportunity to fist-forward certain negotiations, and can have the cultural insight to know when it is better to move more slowly. The employee at the home office who can communicate well with foreign clients over the telephone or by fax machine is an obvious asset to the firm.

单选题I get a lot of letters at this time of year from people complaining that they have a cold which won’t go away. There are so many different stories about how to prevent or cure a cold; it’s often difficult to know what to do. Although colds are rarely dangerous, except for people who are already weak, such as the elderly or young babies, they are always uncomfortable and usually most unpleasant. Of course you can buy lots of medicines which will help to make your cold less unpleasant, but you must remember that nothing can actually cure a cold or make it go away any faster. Another thing is that any medicine which is strong enough to make you feel better could be dangerous if you are already taking drugs for some other illness, so always check with your chemist or doctor to see whether they are all right for you. And remember they might make you sleepy. Please don’t try to drive if they do! Lastly, as far as avoiding colds, the best answer is to keep strong and healthy--you’ll have less chance of catching a cold, and if you do, it should not be so bad.
