Microsoft announced this week that its facial-recognition system is now more accurate in identifying people of color, touting (吹嘘）its progress at tackling one of the technology’s biggest biases (偏见). But critics, citing Microsoft’s work with Immigration and Customs Enforcement, quickly seized on how that improved technology might be used. The agency contracts with Microsoft for cloud-computing tools that the tech giant says is largely limited to office work but can also include face recognition. Columbia University professor Alondra Nelson tweeted, “We must stop confusing ‘inclusion’ in more ‘diverse’ surveillance (监管）systems with justice and equality.” Facial-recognition systems more often misidentify people of color because of a long-running data problem： The massive sets of facial images they train on skew heavily toward white men. A Massachusetts Institute of Technology study this year of the face-recognition systems designed by Microsoft, IBM and the China-based Face++ found that facial-recognition systems consistently giving the wrong gender for famous women of color including Oprah Winfrey, Serena Williams, Michelle Obama and Shirley Chisholm, the first black female member of Congress. The companies have responded in recent months by pouring many more photos into the mix, hoping to train the systems to better tell the differences among more than just white faces. IBM said Wednesday it used 1 million facial images, taken from the photo-sharing site Flickr, to build the “world’s largest facial data-set” which it will release publicly for other companies to use. IBM and Microsoft say that allowed its systems to recognize gender and skin tone with much more precision. Microsoft said its improved system reduced the error rates for darker-skinned men and women by “up to 20 times,” and reduced error rates for all women by nine times. Those improvements were heralded（宣布）by some for taking aim at the prejudices in a rapidly spreading technology, including potentially reducing the kinds of false positives that could lead police officers misidentify a criminal suspect. But others suggested that the technology's increasing accuracy could also make it more marketable. The system should be accurate, “but that’s just the beginning, not the end, of their ethical obligation,” said David Robinson, managing director of the think tank Upturn. At the center of that debate is Microsoft, whose multimillion-dollar contracts with ICE came under fire amid the agency’s separation of migrant parents and children at the Mexican border. In an open letter to Microsoft chief executive Satya Nadella urging the company to cancel that contract, Microsoft workers pointed to a company blog post in January that said Azure Government would help ICE “accelerate recognition and identification.” “We believe that Microsoft must take an ethical stand, and put children and families above profits,” the letter said. A Microsoft spokesman, pointing to a statement last week from Nadella, said the company’s “current cloud engagement” with ICE supports relatively anodyne（温和的）office work such as “mail, calendar, massaging and document management workloads.” The company said in a statement that its facial-recognition improvements are “part of our going work to address the industry-wide and societal issues on bias.” Criticism of face recognition will probably expand as the technology finds its way into more arenas, including airports, stores and schools. The Orlando police department said this week that it would not renew its use of Amazon. com’s Rekognition system. Companies ”have to acknowledge their moral involvement in the downstream use of their technology,” Robinson said. “The impulse is that they’re going to put a product out there and wash their hands of the consequences. That’s unacceptable.”【小题1】What is “one of the technology’s biggest biases” in Paragraph 1? A．Class bias. B．Regional difference. C．Professional prejudice. D．Racial discrimination.

一道英语阅读题：The word “colossal” in Line 3 most likely means ______.Computers may one day turn night into day—with good old,natural sunlight.Colossal computer-controlled mirrors,thousands of feet across,may one day orbit the earth,reflecting sunlight onto a darkened United States.Some Scientists say that 16 of these mirrors,each about a half mile across,could aim their reflected light at one area on the earth that was about 200 miles by 300 miles.That much light would equal about 56 moons.The mirrors would be so high that they could catch the sun’s light as it was shining on the other side of the earth.The mirrors could orbit—thousands of miles high—at the same speed as the earth turns on its axis (轴).That way,themirrors would always be over the same spot.The aluminum-coated (涂铝的),plastic mirrors could be folded up and packed into a spaceship,according to the scientists.Once released a few hundred miles in space,the mirrors,powered by a solar-powered engine,could mark the rest of the trip into space on their own.The scientists say that the computer-controlled mirrors could also be made to tilt (倾斜) slowly,so the reflected sunlight would sweep slowly along the surface of the earth.For example,as night fell,the mirrors could be tilted to light up Boston.Later on,as darkness spread slowly westward.Chicago,for example,then San Francisco could be lit up.The reflected sunlight would allow these cities to save up electricity.And in emergencies,such as power-failures,the mirrors could light up the affected area.What no one knows yet is what effect this artificial daytime would have on plants,animals,and humans.Would it confuse some animals and harm plants that are used to regular day-night cycles?The scientists recommend that studies be done to find out what had effects there might be.The word “colossal” in Line 3 most likely means ______.A) nuclear-poweredB) orbitingC) giantD) spinning(D)为什么选D啊?

question or statement.Hot pot is a traditional dish in China. It is believed to date back more than 1,000 years to the time of the Jin Dynasty. Hot pot's origins can be found in the dining practices of Mongolian horsemen who rode across the steppe and into northern China. Legend has it that the Mongols used their helmets as pots to simmer (炖) broth (汤底) over open fires, and cooked chunks of meat in the broth.Hot pot cooking seems to have spread to northern China during the Tang Dynasty. In the regional variations developed with different ingredients such as seafood. In the centuries that witnessed the growth of the Song Dynasty, hot pot moved — and changed — further south, with each successive region adapting it to their local ingredients and tastes.The ingredients in a hot pot vary a lot from region to region. Perhaps the most famous hot pot is the Chongqing or Sichuan hot pot. It features a dark red broth chock-full (塞满了的) of spices, chili peppers, and the uniquely mouth-numbing Sichuan peppers. In Beijing and elsewhere in the north, hot pot broth tends to be mild and, compared to its racy southern "cousins", a little light. In the northeast of China, a kind of local sauerkraut (酸菜) is used to add some tang (强烈的味道), making the broth a bit sour. People can choose a version of hot pot according to their taste.1 Hot pot is believed to date back more than 1,000 years to the time of _______.A. the Jin Dynasty B. the Tang DynastyC. the Song Dynasty D. the Yuan Dynasty

The Harry Potter series, written by J.K. Rowling, is perhaps the most popular set of novels of the modern era. With seven books and many successful films to its name, the series has gathered about 15 billion dollars in sales. How did the series become so popular? The reason can be broken down into several areas.The first book in the series was rejected 12 times before it was picked up by Bloomsbury—a small publisher in England. So receiving this contract was Rowling's first step to success. However, getting a book contract does not ensure the success of a book. The story was soon loved by children and adults alike. In light of this, Bloomsbury Publishing published a second version of the books with “adult” (less colorful and more boring) book covers. This made it easier for a full range of ages to enjoy the series.Another factor that worked like a charm was that the publisher and Rowling herself, through the books, conducted midnight releases, promotions, and pre-ordering more readers. Customers who feared that their local bookstore would run out of copies responded by pre-ordering over 700,000 copies before the July 8, 2000 release.What does the underlined word “releases” (Para. 3) mean?A. The activity that frees or expresses energy or emotion.B. The announcement about the book’s publishing information.C. The sales of books that is available only at midnight.

The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding. [共5题](1)What kind of manager is needed in present international business and foreign investment? [本题2分]A. The man who represents a large multi-million-dollar corporation. B. The man with knowledge of foreign languages and skills in cross-cultural communication. C. The man who is wealthy and impersonal. D. The man who can negotiate with his foreign counterparts.
