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.

Wolves belong to the animal family Canidae, which also includes such animals as the jackal, coyote, fox, and dog. Some of these canids, such as the fox, are solitary hunters and raise their young alone; wolves, ___51____, are regarded as social animals, living in well-organized packs of 8 to 20 or more animals. A pack generally includes only one breeding pair and their offspring, but occasionally it may include one or two ____52___ wolves. Occasionally, different packs join together during difficult times, such as harsh winters, to find and bring down large game(猎物). The ___53____ nature of these packs is remarkable. Raising the pups, for instance, is a collective responsibility. Adult wolves in the pack may bring ___54___ to the mother while she is nursing; later they will feed the growing pups on partly ___55____ food they have regurgitated(反刍). Various adult wolves watch over the young ones, ___56_____ them, playing with them, and teaching them to hunt. Wolves, which usually live in northern forests, often search for food with all other wolves in the pack, working collectively to bring down large animals such as caribou and elk. Each pack usually has its own ____57___ for hunting. Wolves are protective of these territories, and they sometimes kill other wolves that trespass(擅自进入). When members of a pack are separated, ____58____--including howling, yelping and growling—help them communicate across long distances, stay in touch during hunting forays, and ____59____ their territory. Each wolf occupies a particular place in the hierarchy(等级) of the pack, in which high-ranking, powerful wolves—called dominant wolves--___60____ the weaker, subordinate wolves. The leading male wolf is often designated(指定) the alpha male, and the leading female is the alpha female.

The subordinate wolf, ___61____, crouches down, lowers its tail between its legs, and flattens its ears; it may whine as well. It is possible that this submissive(温顺的) posture may play an important role in creating ___62____ bonds between wolves. According to current studies, the alpha pair in wolf pack is the only ___63____ pair. Alpha status in a wolf pack is ___64____ permanent, however. New research suggests that as younger wolves pair off, they assume the alpha roles, and animals no longer breeding ___65___ their alpha status. 51. A. otherwise B. thus C. plus D. however 52.

阅读下列短文，从每题所给的A、B、C和D项中，选出最佳选项。 Language learning begins with listening. Children are greatly different in the amount of listening they do before they start speaking, and later starters are often long listeners. Most children will “obey” spoken instructions some time before they can speak, though the word “obey”is hardly accurate as a description of the eager and delighted cooperation usually shown by the child. Before they can speak, many children will also ask questions by gesture and by making questioning noises. Any attempt to study the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves as particularly expressive as delight, pain, friendliness, and so on. But since these can’t be said to show the baby’s intention to communicate, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new words to their store. This self-imitation(模仿)leads on to deliberate(有意的)imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imitations can be considered as speech. It is a problem we need to get out. The meaningof a word depends on what a particular person means by it in a particular situation and it is clear that what a child means by a word will change as he gains more experience of the world .Thus the use at seven months of “mama”as a greeting for his mother cannot be dismissed as a meaningless sound simply because he also uses it at other times for his father, his dog, or anything else he likes. Playful and meaningless imitation of what other people say continues after the child has begun to speak for himself, I doubt, however whether anything is gained when parents take advantage of this ability in an attempt to teach new sounds.一、 Before children start speaking________. A、they need equal amount of listening B、they need different amounts of listening C、they are all eager to cooperate with the adults by obeying spoken instructions D、they can’t understand and obey the adult’s oral instructions 二、 Children who start speaking late ________. A、may have problems with their listening B、probably do not hear enough language spoken around them C、usually pay close attention to what they hear D、often take a long time in learning to listen properly 三、 A baby’s first noises are ________. A、an expression of his moods and feelings　　 B、an early form of language C、a sign that he means to tell you something　 D、an imitation of the speech of adults 四、 The problem of deciding at what point a baby’s imitations can be considered as speech________. A、is important because words have different meanings for different people B、is one that should be properly understood because the meaning of words changes with age C、is not especially important because the changeover takes place gradually D、is one that should be completely ignored(忽略)because children’s use of words is often meaningless 五、 The author implies________. A、parents can never hope to teach their children new sounds B、even after they have learnt to speak, children still enjoy imitating C、children no longer imitate people after they begin to speak D、children who are good at imitating learn new words more quickly
