A horrific mudslide hit Monte cio California just days after the shocking wildfires that burned down . the state . Since early Tuesday Monte cio has been greatly affected by massive mudslides that have now de strongd homes taken lives and caused incredible scenes At least five people have been confirmed dead while many others have been reported missing . Hundreds of homes have been completely covered by waxes of mud causing the government to evacuate people in the area The National Gallery has always given pride of place to Peter Paul Rubens's Samson and Delilah，listing it among the “highlights”of its collection, since it purchased the picture at Christie's in 1980 for a thenrecord price.Critics(评论家) have long suggested that the painting is not really by Rubens. And now a series of scientific tests employing groundbreaking AI technology have concluded that the 17th-century Flemish painter could never have painted it.“The results are quite astonishing," Dr. Carina Popovice ，he scientist who carried out the study, told theObserver.“The algorithm(算法) has returned a 91%probability for the artwork not being authentic.”The AItechnology analyses different features of an artist's work，including brushstroke (笔刷) patterns. Popovici saidthat everything that's not by the hand of the assumedartist will come out with a negative probability and thatthe technology can produce accurate results even foartists who greatly changed their style across theircareers as every artist has a unique brushstroke.The AI analysis was carried out by Art Recognition，a Swiss company based near Zurich of which Popovici isco-founder. It has analyzed 400 works with thistechnology，and has an ongoing collaboration with TilburgUniversity in Holland.Critics have long argued that it is only a copy of a Rubens original that is known to have been painted between 1608 and 1609 for his Antwerp sponsor Nicolaas Rockox which then vanished after his death in 1640.Then it was not until in 1929 when it appeared again thatthe painting was collected by the National Gallery.The significance of this new AI method of authentication is potentially groundbreaking. Short of human subjectivity,emotion and commercial interests, the software is coldly objective and scientifically accurate. Many questionable works were given the credit to Rubens at the beginning of the 20th century. There is today a clear need for more reliable methods of judgment.8. Why does the National Gallery pay much attention tothis painting?A. It is one of Rubens's works.B. It can give off unique light.C. It receives much criticism.D. It is thought of great value.9. What can be inferred about the artists?A. They are not satisfied with the AI technology.B. They wish their artworks to be valued.C. They have unchangeable painting habits.D. They can create some artworks beyond times.10.What does the underlined word“vanished" mean in Paragraph 5?A. Broke.B. Arrived.C. Disappeared.D. Adjusted.11.What is the main idea of the last paragraph?A. The AI technology has many advantages.B. The AI technology is short of human subjectivity.C.

Why does electronic shopping exist For customers , it is because of not I only the high level of convenience , but also the broader selection , competitive pricing and greater access to information . For organizations , it increases their customers value and sustainable capabilities , next to the increased profits The main idea of online shopping is not in having a good - looking website that could be listed in a lot of search engines and it is not about the art behind the site . Nor is it just about spreading information . However it is all about building relationships and malding money . Mostly organizations try to adopt techniques of online shopping without understanding these techniques . Rather than supporting the organization s culture and brand name the website should satisfy consumers expectations Design and relation When the customers go to an online shop , a couple of factors determine whether they will return to the site . The most important factors are the ease of use and the presence of user - friendly features . It is not hard to find evidence of the success of the“sharing economy", in which people rent beds, cars and other underused assets directly from each other, or via the internet. One pointer is the large amount of demand and supply. Airbnb claims that 11m people have used its website to find a place to stay. Lyft, a company that matches people needing rides and drivers wanting a few dollars, has spread from San Francisco to 30-odd American cities. Another sign is the frothy values (泡沫价值) placed on sharing- economy companies: Airbnb is estimated to be worth 10billion,more than hotel chains such as HyattandWyndham,andLyftrecentlyraised250m from venture capitalists. But perhaps the most flattering- -and least welcome- indicator of the sharing economy's rise is the energy being devoted by governments, courts and competitors to preventing it. The main battlegrounds are the taxi and room-rental businesses. A court in Brussels has told Uber, another San Francisco ride-sharing and taxi-services startup, to stop operating in the city. Other cities have banned their services outright, or tried other ways of putting spokes in their wheels. Meanwhile the Hotel Association of New York has been lobbying for (游说) stricter enforcement of a rule that bans absent owners from letting their apartments for less than 30 days, which makes most of Airbnb's listings there illegal. The newcomers' opponents, whether competitors, officials or worried citizens, complain that the likes of Airbnb and Lyftdodge (躲避) the rules and taxes that apply to conventional businesses. Regulations exist to keep hotel rooms clean and fire alarms in working order, to stop residential areas being filled with unlicensed hotels, and to see that drivers are insured, checked for criminality and tested on their knowledge of the streets. Cowboys such as Airbnb, Lyft and Uber, their critics claim, are a danger to an unsuspecting public. The objectors have half a _point. Taxes must be paid: a property-owner who rents a room should declare the income, just as a hotel should. Safety is also a concern: people want some assurance that once they bed down for the night or get into a stranger's car they will not be attacked or robbed. Zoning (划分区域) and planning are also an issue: peace- loving citizens may well object if the house next door becomes a hotel. Sharing-economy firms are trying to mitigate (缓和) these problems. They have tightened insurance cover for their drivers and have offered to collect hotel taxes. They have an interest in their participants' good behavior: as hosts, guests, drivers and passengers all rate each other online, their need to protect their reputation helps to maintain standards and keep people honest. But if consumers want to go for the cheaper, less-regulated service, they should be allowed to do so. The truth is that most of the rules that the sharing economy is breaking have lttle to do with protecting the public. The opposition to Lyft and Uber is coming not from customers but from taxi companies, which understand that GPS makes detailed knowledge of the streets redundant (多余的) and fear cheaper competition. [小题1] According to Paragraph 1, the success of the“sharing economy”is indicated by the fact thatA. many people are trading their underused assets freely via the internetB. growth in online rental demand has exceeded supply in many regionsC. its total capital value has surpassed that of conventional businessD. sharing economy companies are suffering from a number of attacks[小题2] Opponents complain that the taxi and room-rental businessesA. frequently make anti-competitive market behaviorB. are often involved in illegal business practicesC. are lacking in necessary rules and regulationsD have caused a lot of accidents and crimes[小题3] By "have a half point" in Paragraph 4, the author probably means the objectorsA. fail to indentify the safety problems existing among sharing economy firmsB. have overstated the dangers brought about by sharing-economy firms to the publicC. fail to realize the need of zoning and planning in sharing economyD. have overestimated the impact of sharing economy firms on the traditional counterparts[小题4] The author believes that the current opposition to sharing economy mainly reflects_A. the mission of protecting the publicB. the complaints from service consumersC. the fear among conventional businessesD. the dissatisfaction among service providers[小题5] What is the author's attitude toward the practice of San Francisco authorities?A.IndifferentB.SkepticalC.Disapproving.D.Positive.

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 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.

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.

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.

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.
