With the coming of big data age, data science is supposed to be starved for, of which the adaption can point a profound change in corporate competitiveness. Companies, both born in the digital era and traditional world are showing off their skills in data science. Therefore, it seems to have been creating a great demand for the experts of this type.Mr. Carlos Guestrin, machine learning professor from University of Washington argues that all software applications will need inbuilt intelligence within five years, making data scientists-people trained to analyze large bodies of information-key workers in this emerging "cognitive" technology economy. There are already critical applications that depend on machine learning, a subfield of data science, led by recommendation programs, fraud detection systems, forecasting tools and applications for predicting customer behavior.Many companies that are born digital-particularly internet companies that have a great number of real-time customer interactions to handle-are all-in when it comes to data science. Pinterest, for instance, maintains more than 100 machine learning models that could be applied to different classes of problems, and it constantly fields requests from managers eager to use this resource to deal with their business problem.The factors weighing on many traditional companies will be the high cost of mounting a serious machine-learning operation. Netflix is estimated to spend 150m a year on a single application and the total bill is probably four times that once all its uses of the technology are taken into account.Another problem for many non-technology companies is talent. Of the computer science experts who use Kaggle, only about 1, 000 have deep learning skills, compared to 100, 000 who can apply other machine learning techniques, says Mr. Goldbloom. He adds that even some big companies of this type are often reluctant to expand their pay scales to hire the top talent in this field.The biggest barrier to adapting to the coming era of "smart" applications, however, is likely to be cultural. Some companies, such as General Electric, have been building their own Silicon Valley presence to attract and develop the digital skills they will need.Despite the obstacles, some may master this difficult transition. But companies that were built, from the beginning, with data science at their center, are likely to represent serious competition.Which one is obstacle for many traditional companies to popularize learning operation?A.Technological problem.B.Expert crisis.C.High cost.D.Customer interactions.What can not be inferred from the passage about the machine learning?A.Machine learning operations are costly in Netflix.B.Machine learning plays an important role in existent applications.C.Machine learning experts are not highly paid in some non-technology companies.D.Machine learning models are not sufficient to solve business problems in Pinterest.What's the author's main purpose in writing this article?A.To point out the problems facing machine learning experts.B.To call on companies to cultivate more experts in data science.C.To tell the readers the present situation of data science.D.To advice non-technology companies to look beyond the advantages they face.Which of the following is the best title for this passage?A.Data science: A forefront force in tech businessB.Corporate competition: An obstacle to the transitionC.Machine learning: A key to smart technologyD.Technique experts: A decisive factor of the coming era.

Being eco-friendly is not a new concept, but it is certainly taken on a greater sense of urgency in the past few years. With the rising cost of fossil fuels, global warming, and all of the other environmental issues that are coming to light , everyone is looking for ways to reduce their carbon footprint and become more "green." Being energy-conscious can be a good way to help the environment. Turn the heat down, and each degree you turn down the heat saves three percent of heating costs, while each degree you raise the temperature of your air conditioner saves three to four percent of cooling costs. Lower the temperature, and in fact by changing the temperature by two degrees all year, you can save about 2,000 pounds of CO₂a year. Air-dry or hang your clothes instead of using the dryer and save 700 pounds of CO₂a year. Besides using more energy, they are actually dangerous and can cause fires. While most people are familiar with these methods for reducing the impact on the environment, one great way is to replace outdated appliances with more energy efficient models. Most manufacturers are now making their products to the "green" initiative. By changing their manufacturing processes, most manufacturers have found ways to take items that traditionally were not thought of as being "green," and reducing their impact on the environment. One less obvious way to lessen the impact is by buying direct. One thing that people don't consider is where they buy their products. Retail stores utilize a huge amount of resources and inevitably have a huge impact on the environment. Buy products online or direct from the manufacturer, and you are eliminating that high overhead and ecological (生态的) impact. So by simply changing the way you look at your daily habits and the products you buy, you can have a positive impact on your overall carbon footprint.1. The phrase "coming to light" most probably means "becoming ________." (Para. 1)A) settledB) known C) urgentD) serious2. What do most manufacturers do to reduce their impact on the environment?A) Advertise their "green" products.B) Develop CO₂ reduction technology.C) Manufacture more energy-efficient products. D) Sell their products directly to the customers.3. What is the less obvious way for people to contribute to the environment?A) Control CO₂ emission efficiently.B) Update household appliances regularly.C) Make full use of the limited amount of resources.D) Buy products online or directly from the manufacturers. 4. Which of the following practices is NOT helpful to the environment?A) Air-dry or hang your clothes after washing.B) Buy the products we need from retail stores. C) Adjust the temperatures of air conditioners in an economical way.D) Replace the outdated appliances with more "green" models.5. This passage mainly discusses how to ________.A) manufacture more "green" productsB) become energy-conscious and eco-friendlyC) turn down the temperature of the air conditionerD) reduce people's impact on the environment in daily life

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.

Most children with healthy appetites are ready to eat almost anything that is offered them and a child rarely dislikes food (51) it is badly cooked. The way a meal is cooked and served is most important and an (52) served meal will often improve a child’s appetite. Never ask a child whether he likes or dislikes a food and never (53) likes and dislikes in front of him or allow anybody else to do so. If the father says he hates fat meat or the mother refuses vegetables in the child’s hearing he is (54) to copy this procedure. Take it (55) granted that he likes everything and he probably will. Nothing healthful should be omitted from the meal because of a (56) dislike. At meal times it is a good idea to give a child a small portion and let him (57) back for a second helping rather than give him as much as he is likely to eat all at once. Do not talk too much to the child (58) meal times, but let him get on with his food, and do not allow him to leave the table immediately after a meal or he will soon learn to swallow his food (59) he can hurry back to his toys. Under (60) circumstances must a child be coaxed or forced to eat.55（）。A. withB. asC. overD. for

Americans experience more food recalls (召回) today than they did five years ago, especially when it comes to meat and poultry (家禽). Meat and poultry recalls increased by two-thirds from 2013 to 2018, while food recalls overall went up 10%, according to the report recently published by the U.S. Public Interest Research Group.Meanwhile, the U.S. Centers for Disease Control and Prevention estimates (估计) 48 million people get sick, 128,000 are hospitalized and 3,000 die from food-borne disease each year in the U.S. "We are looking for the farm-to-fork preventative solutions," said Adam Garber, the research group's consumer watchdog. "By doing that, we can protect people's health."Over the five-year period, poultry posted the most recalls (168), followed by beef (137) and pork (128). The report shows the most serious meat recalls are on the rise. Among meat and poultry, the number of Class I recalls has increased by 83%, nearly doubling. Class I, the most serious of the recalls, is issued when there is a reasonable probability that the food will cause health problems or death.53. When would Class I recalls be issued?A. When the food is likely to cause health problems or death.B. When there are too many complaints from customers.C. When the food problem lasts for five years.D. When the product quality is below standard.

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.
