Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant to help handle the enormous number of student questions in the online class,Knowledge-Based Artificial Intelligence.This online course is a core requirement of Georgia Tech's online Master of Science in Computer Science program.Professor Goel already had eight teaching assistants,but that wasn't enough to deal with the overwhelming number of daily questions from students. Many students drop out of online courses because of the lack of teaching support.When students feel confused and reach out with questions that go unanswered,their motivation to continue begins to fade.Professor Goel decided to do something to remedy (改进) this situation and his solution was to create a virtual assistant named Jill Watson,which is based on the IBM Watson platform. Goel and his team developed several versions of Jill Watson before releasing her to the online forums.At first,the virtual assistant wasn't too great.But Goel and his team sourced the online discussion forum to find all the 40,000 questions that had ever been asked since the class was launched.Then they began to feed Jill with the questions and answers.After some adjustments and sufficient time,Jill was able to answer the students' questions correctly 97% of the time.The virtual assistant became so advanced and realistic that the students didn't know she was a computer.The students,who were studying artificial intelligence,were interacting with the virtual assistant and couldn't tell it apart from a real human being.Goel didn't inform them about Jill's true identity until April 26.The students were actually very positive about the experience. The goal of Professor Goel's virtual assistant next year is to take over answering 40% of all the questions posed by students on the online forum.The name Jill Watson will,of course,change to something else next semester.Professor Goel has a much more hopeful outlook on the future of artificial intelligence than,say,Elon Musk,Stephen Hawking,Bill Gates or Steve Wozniak.(1)What do we learn about Knowledge-Based Artificial Intelligence? ____ A.It is a robot that can answer students' questions.B.It is a course designed for students to learn online.C.It is a high-tech device that revolutionizes teaching.D.It is a computer program that aids student learning.(2)What problem did Professor Goel meet with? ____ A.His students were unsatisfied with the assistants.B.His course was too difficult for the students.C.Students' questions were too many to handle.D.Too many students dropped out of his course.(3)What do we learn about Jill Watson? ____ A.She turned out to be a great success.B.She got along pretty well with students.C.She was unwelcome to students at first.D.She was released online as an experiment.(4)How did the students feel about Jill Watson? ____ A.They thought she was a bit too artificial.B.They found her not as capable as expected.C.They could not but admire her knowledge.D.They could not tell her from a real person.

149.It is difficult to ________ the implication between the lines.A. get toB. get withC. get atD. get down

[2015·辽宁省实验高三四模,(C)29~32]阅读下面短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。CFinding a good work-at-home job is not easy. Although you see all the online advertising, there aren’t that many of them.

  • 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.

  • 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.
