Students taking Georgia Tech's online Knowledge-Based Artificial Intelligence course received some surprising news. Jill Watson one of the nine teaching assistants(TAs) that had helped them finish the challenging course for the past five months was not a ‘‘she'' but an “it”—an intelligent robot!

    Watson is the brainchild of Ashok Goel, who teaches the popular online course. The Professor-of Computer and Cognitive Science in the School of Interactive Computing came up with the idea as a way to deal with a number of questions posed by students in the online forums(论坛). According to Goel, every time the course is offered, the 300 or so students that enroll post over 10,000 questions which are often repetitive. This led Goel to wonder if a smart robot would handle the questions which require standard responses.

    Having worked' with IBM's Watson technology platform in the, the professor knew it would be ideal for his artificial TA: Jill Watson. The artificial intelligence system that uses natural language processing and machine learning to analyze large amounts of data has even been cleverer than human competitors on the television show. It would therefore easily be able to handle routine questions that required little “thinking”.

    The professor and his team of graduate students began by populating Jill's memory with 40,000 questions and answers from past terms. Then came the testing stage. At first, Jill was not very good and often gave strange answers. It often got stuck on certain keywords. By the end of the semester, Jill had attained enough knowledge and skills to participate in forums without any management from Goel, or the other assistants.

    The days of the hunter are almost over in India. This is partly because there is practically nothing left to kill, and partly because some steps have been taken, mainly by banning tiger-shooting, to protect those animals which still survive.

    Some people say that Man is naturally a hunter. I disagree with this view. Surely our earliest forefathers, who at first possessed no weapons, spent their time digging for roots, and were no doubt themselves often hunted by meat-eating animals.

    I believe the main reason why the modern hunter kills is that he thinks people will admire his courage in overpowering dangerous animals. Of course, there are some who truly believe that the killing is not really the important thing, and that the chief pleasure lies in the joy of the hunt and the beauties of the wild countryside. There are also those for whom hunting in fact offers a chance to prove themselves and risk death by design; these men go out after dangerous animals like tigers, even if they say they only do it to rid the countryside of a threat. I can respect reasons like these, but they are clearly different from the need to strengthen your high opinion of yourself.

    The greatest big-game hunters expressed in their writings something of these finer motives. One of them wrote.

    “You must properly respect what you are after and shoot it cleanly and on the animal's own territory(领地). You must fix forever in your mind all the wonders of that particular day. This is better than letting him grow a few years older to be attacked and wounded by his own son and eventually eaten, half alive, by other animals, Hunting is not a cruel and senseless killing - not if you respect the thing you kill, not if you kill to enrich your memories, not if you kill to feed your people.”

    I can understand such beliefs, and can compare these hunters with those who hunted lions with spears(矛) and bravely caught them by the tail. But this is very different from many tiger-shoots I have seen, in which modern weapons were used. The so-called hunters fired from tall trees or from the backs of trained elephants. Such methods made tigers seem no more dangerous than rabbits.

Much meaning can be conveyed clearly in our eyes, so it is often said that eyes can speak.

{#blank#}1{#/blank#} On a bus you may look at a stranger, but not for too long. And if he senses that you are staring at him, he may feel uncomfortable.

The same is true in our dailylife. If you are stared at for more than necessary, you will look at yourself up and down to see if there is anything wrong with you.{#blank#}2{#/blank#} Eyes do speak, right?

Looking too long at someone may seem to be rude and aggressive. {#blank#}3{#/blank#} If a man stares at a woman for more than 10 seconds and refuses to look away from her, his intentions are obvious. He wishes to attract her attention, and let her know that he is admiring her.

However, when two persons are engaged in a conversation, the speaker will only look into the listener's eyes from time to time to make sure that the listener does pay attention to what the former is speaking. {#blank#}4{#/blank#} If a speaker looks at you continuously when speaking as if he's trying to control you, you will feel awkward. A poor liar usually exposes himself by looking too long at the victim. He wrongly believes that looking straight in the eye is a sign of honest communication. {#blank#}5{#/blank#}

Actually, eye contact should be made based on a specific relationship and situation.

A. On the contrary, it will give him away.

B. Do you have such a kind of experience?

C. That's what normal eye contact is all about.

D. Actually, continuous eye contact is limited to lovers only.

E. After all, everybody likes to be stared at for quite a long time.

F. But things are different when it comes to staring at the opposite sex.

G. If nothing goes wrong, you will feel annoyed at being stared at that way.

    On Tuesday. Google announced a new feature (特点) for the Google Assistant. People can send reminders to friends and family on their phone or their Google Home equipment.

    Google has named the new feature Assignable Reminders. Here's how the new Assignable Reminders feature works with Google Assistant.

    You start off by simply starting the Google Assistant by saying "Hey Google" or by whatever shortcut (快捷键) you have set on your phone. After this, you can tell Google Assistant to remind someone of something at a certain time.

    This feature will also be feasible on the Google Home smart speaker, or a smart display which works with Google Assistant. The person receiving the reminder can also replay the reminder by asking Google Assistant to show them a list of all their reminders.

    These reminders can only be sent to people who are already listed as family in your Google account (账户) or people who are linked (连接) and voice-matched to the same Google Home equipment.

    Another feature built within Assignable Reminders is the ability to set reminders based on someone's place. For example, you can set a reminder for friends to buy you something from a store as soon as they reach there.

    Assignable Reminders will be put into use in the next few weeks in the U.S. , the U.K, and Australia.

    What should you think about in trying to find your career? You are probably better at some school subjects than others. {#blank#}1{#/blank#} A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to do well at school. On the other hand, you may not have any specially strong or weak subjects but your records show a general good result. {#blank#}2{#/blank#} Knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.

    Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metal work or cooking and look for a job where you can improve these skills.

    {#blank#}3{#/blank#} You may have learned how to get to work on time and get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a certain industry or career you see from the inside in a part-time job.

    {#blank#}4{#/blank#} You may be all thumbs when you deal with tools; perhaps you are a poor speller or cannot add up a column of figures. It is better to face any weaknesses than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not feel sorry for it. {#blank#}5{#/blank#}

A. This does not have direct value for future job hunting.

B. These may show strengths that you can use in your work.

C. Facing your weak points is also part of knowing yourself.

D. Having a part-time job is a good way to find out your weak points.

E. Instead, you should recognize that you will have a chance of a fresh start at work.

F. Although not all subjects can be used directly in a job, they may have indirect value.

G. If you have had a part-time job on Saturdays or in the summer, think what you gained from it.
