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.
Goel and his team developed several versions of a virtual assistant named Jill Watson before releasing her to the online forums. At first, the virtual assistant wasn't too great. 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 rosier outlook on the future of artificial intelligence than, say, Elon Musk, Stephen Hawking, Bill Gates or Steve Wozniak.

The first thing to remember is that you must be willing to learn.It doesn’t mean that you must always like the subject.It does mean,however,that you must be willing to do whatever is necessary to learn. Try to understand why it is important and how it will help you now and later to do and learn other things.Knowing mathematics facts will be useful in your whole life. Knowing how to spell makes any kind of writing easier.Sometimes,the subject that you think is going to be uninteresting will be exciting when you begin to work at it and understand it more clearly. Learning things can be fun if you are willing to work with them.
Here is some advice for you: have a certain time each day and a quiet place with good lighting for study,so that you can concentrate on your study without interruptions; have everything ready before you sit down to study, a dictionary,paper,a pen and books; be sure you understand what you should learn before you start; read carefully and pay special attention to the most important things; when memorizing,first find out the main parts and recite the whole thing, check your homework after you finish it; never forget the importance of review and preview.
Don’t try to spend a lot of time researching learning methods.There are many students who know many good learning methods but don’t study well. They forget that the most important useful learning method is to study hard.

【推荐2】Living abroad to study can certainly be an interesting experience but is that alone a good enough reason for spending years far away from home? To make the experience truly worthwhile, there has to be a goal behind the decision to study abroad. This may be a wish to perfect language skills in a foreign language environment, or a clever move in your career development. You must also consider the costs, not just of living and studying abroad, but of applying. Most universities now charge application fees for international students.
If after considering these points you are sure that you want to apply to study abroad, your next step is to choose the right programme of studies. Research your choices and select carefully. You must do your homework well. Most universities have information online but you can also email and ask them to send you more details. You can find a lot of information on school ranking from education websites. But read carefully. Different universities emphasize different strengths. Don’t just think about the university’s reputation; look for the most suitable for your goals.
Next, you must deal with a large pile of paperwork. This involves filling in application forms, preparing your school records, and getting reference letters. Reading the instructions and requirements of the universities carefully is of great importance. Sadly, many fine applicants get kicked out in the first round, simply because they don’t follow the application procedure properly.
Money is another important consideration. Some scholarships are provided by governments, others by schools and colleges. This information, again, can be found on the Internet. If you find a scholarship that is suitable for you, follow the application procedure carefully; the earlier you apply, the better your chance of getting it.

【推荐2】The skin is an essential part of your body and its largest organ. You have three layers (层) of skin which act as a barrier against disease, poisons and the sun’s harmful rays. The functions of your skin are also very complex: it keeps you warm or cool; it prevents your body from losing too much water; it is where you feel cold, heat or pain and it gives you your sense of touch. So as you can imagine, if your skin gets burned it can be very serious. First aid is a very important first step in the treatment of burns.
Causes of burns
You can get burned by a variety of things: hot liquids, steam, fire, radiation (by being close to high heat or fire, etc. ), the sun, electricity or chemicals.
Types of burns
There are three types of burns. Burns are called first, second or third degree burns, depending on which layers of the skin are burned.
• First degree burns
These affect only the top layer of the skin. These burns are not serious and should feel better within a day or two. Examples include mild sunburn and burns caused by touching a hot pan, stove or iron for a mordent (熨烫熨斗).
• Second degree burns
These affect both the top and the second layer of the skin. These burns are serious and take a few weeks to heal. Examples include severe sunburn and burns caused by hot liquids.
• Third degree burns
These affect all three layers of the skin and any tissue and organs under the skin. Examples include burns caused by electric shocks, burning clothes, or severe petrol fires. These burns cause very severe injuries and the victim must go to hospital at once.
Characteristics of burns
First degree burns
• dry, red and mildly swollen
• mildly painful
• turn white when pressed
Second degree burns
• rough, red and swollen
• watery surface
• extremely painful
Third degree burns
• black and white and charred
• swollen; often tissue under them can be seen
• little or no pain if nerves are damaged; may be pain around edge of injured area
1. According to Paragraph 1, the functions of the skin include ________.A.regulating body temperature | B.reflecting the sun’s harmful rays |

【推荐3】Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood.
Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.
This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil—make the rain in—and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert.

Can a Robot Really Freestyle?
Engineers at the Georgia Institute of Technology, led by Gil Weinberg, have designed the first musical robot capable of not only playing music, but creating it. His name is Shimon. Weinberg, who is a musician, engineer, and professor of musical technology, found himself in a creative rut (俗套) and decided to create a robot that could inspire him with new musical ideas. Shimon was trained on a vast data set of everything from progressive rock to jazz to rap. His works really surprise human listeners.
Up until recent advancements, applications of AI (artificial intelligence) have mostly consisted of well-defined tasks, but many are concerned that new technology like Shimon could result in lost jobs for millions of people, even those in creative industry.
While the concern of an offing future in which humans are entirely replaced by robots certainly isn’t unfounded, a much more likely future is one in which robots work alongside humans to improve their work. Experts say that AI will actually create jobs for humans, not des troy them. The Guardian recently reported that by 2037, AI will create more than 7 million new jobs in the healthcare, education, and science fields in the UK.
Shimon is showing us what can happen when robots don’t just work for us, but with us. Instead of putting any of our favorite musicians out of work, robots will certainly be challenging and inspiring them in new ways. The cooperation between humans and robots can produce new and attractive music, leading to novel musical outcomes. Thanks to the innovation of Weinberg and his team, rap battles, Jam sessions, and symphony orchestras alike may begin to look and act considerably different.
1. What can Shimon do?2. Why did Gil Weinberg create Shimon?
3. How do many people like the applications of AI in the field of work?
4. According to the writer, what effect will the applications of AI have on creative industry?
【推荐3】The next generation of robots will be able to see objects, will have a sense of touch, and will make critical decisions.
Engineering skilled and computer technology are developing artificial vision for robots. With the ability to “see”, robots can identify and inspect one specific class of objects out of a pile of different kinds of materials. One robot vision system uses of electronic digital cameras containing many rows of lights sensitive materials measure the intensity of light and convert the light rays into a range of numbers. The numbers are part of a gray-scale system in which brightness is measured in a range of values. One scale ranges from 0 to 15, and another from 0 to 255. The 0 is represented by black. The highest number is white. The numbers in between represent different shades of gray. The computer then makes the calculations and converts the numbers into a picture that shows an image of the object in question. It is not yet known whether robots will one day have vision as good as human vision. Technicians believe they will, but only after years of development.
Engineers working on other advances are designing and experimenting with new types of articulated (有关节的) metal hands and fingers, giving robots a sense of touch. Other engineers are writing new programs allowing robots to make decisions such as whether to abandon defective parts in finished products. To do this, the robot will also have to be capable of identifying those perfect and defective parts.
These future robots, assembled (装配,组合) with a sense of touch and the ability to see and make decisions, will have plenty of work to do. They can be used to prospect for minerals on the ocean floor or in deep areas of mines too dangerous for humans to enter.
They will work as gas station attendants, firefighters, house-keepers, and security personnel. The robot business will continue to grow also. Financial analysts believe this business will soar from a $ 100 million-industry at the start of the 1980s to a $5-billion industry by the early 2010s. Anyone wanting to understand the industry of the future will have to know about robots.
