I Know Just How You Feel
Do you feel sad？ Happy？ Angry？ You may think that the way you show these emotions is unique. Well, think again. Even the expression of the most personal feelings can be classified, according to Mind Reading, a DVD displaying every possible human emotion. It demonstrates 412 distinct ways in which we feel: the first visual dictionary of the human heart.
Attempts to classify expressions began in the mid-1800s, when Darwin divided the emotions into six types -- anger, fear, sadness, disgust, surprise and enjoyment.【46】Every other feeling was thought to derive from Darwin's small group. More complex expressions of emotion were probably learned and therefore more specific to each culture. But now it is believed that many more facial expressions are shared worldwide.【47】The Mind Reading DVD is a systematic visual record of these expressions.
The project was conceived by a Cambridge professor as an aid for people with autism (孤独症), who have difficulty both reading and expressing emotions. But it quickly became apparent that it had broader uses. Actors and teachers, for example, need to understand a wide range of expressions. The professor and his research team first had to define an "emotion".【48】Using this definition, 1,512 emotion terms were identified and discussed. This list was eventually reduced to 412, from "afraid" to "wanting".
Once these emotions were defined and classified, a DVD seemed the clearest and most efficient way to display them. In Mind Reading, each expression is acted out by six different actors in three seconds.【49】The explanation for this is simple: we may find it difficult to describe emotions using words, but we instantly recognise one when we see it on someone's face. "It was really clear when the actors had got it right," says Cathy Collis, who directed the DVD. "Although they were given some direction," says Ms Collis, "the actors were not told which facial muscles they should move.【50】" For example, when someone feels contempt, you can't say for certain that their eyebrows always go down.
Someone who has tried to establish such rules is the American, Professor Paul Ekman, who has built a database of how the face moves for every emotion. The face can make 43 distinct muscle movements called "action units". These can be combined into more than 10,000 visible facial shapes. Ekman has written out a pattern of facial muscular movements to represent each emotion.
A. We thought of trying to describe each emotion, but it would have been almost impossible to make clear rules for this.
B. These particular muscles are difficult to control, and few people can do it.
C. Research has also been done to find out which areas of the brain read emotional expressions.

F. Any other method of showing all the 412 emotions, such as words, would have been far less effective.

A Unique Educational Center
It may look like just another playgroup, but a unique educational center in Manhattan is really giving babies something to talk about. "It&39;s a school to teach languages to babies and young children with games, songs--some of the classes also have arts and crafts," said Francois Thibaut,the founder of the Langrage Workshop for Children, a place where babies become bilingual.
Children as young as few months are exposed to French and Spanish before many of them can even speak English. Educators use special songs and visual (视觉的) aids to ensure that when a child is ready to talk, the languages will not be so foreign. "Children have a unique capacity to learn many languages at the same time," said Thibaut. "Already at nine months, a child can tell the differences between the sounds he or she has heard since birth and the sounds he or she has never heard yet." Thibaut says the best time to expose children to language is from birth to 3 years old.
For the last 30 years, the school has been using what it calls the Thibaut Technique, a system that combines language lessons with child&39;s play.
"I always wanted to learn Spanish, but by the time I got to high school it was too late to pick it up and speak fluently," said Marc Lazare, who enrolled his son at the school. "I figured at this age,two, it&39;s a perfect time for him to learn."
Aside from learning a language, the kids also gain a tremendous sense of confidence. One young student boasted that aside from French, she can speak five languages (though that included "monkey" and "lion"). The school gives children the tools to communicate, and sometimes that gives them an advantage over their parents. "I think they sometimes speak French when they think I won&39;t understand them," said parent Foster Gibbons.
Depending on the age group, classes run from 45 minutes up to 2 hours. Even when students are not in class, the program is designed to make sure the learning continues at home. Tapes and books are included so kids can practice on their own.
The word "bilingual" in the first paragraph probably means__________. 查看材料
A.capable of using two languages
B.both clever and confident
C.aware of their own limitations and strengths
D.independent of their parents

Intelligent Machines
1．Medical scientists are already putting computer chips(芯片)directly into the brain to help people who have Parkinson&39;s disease，but in what other ways might computer technology be able to help us？ RayKurzweil is author of the successful book The Age of Intelligent Machines and is one of the world&39;s best computer research scientists．He is researching the possibilities．
2．Kurzweil gets computers to recognize voices．An example of this is Ramona，the virtual(虚拟的) hostess of Kurzweil&39;s homepage，who is programmed to understand what you say．Visitors to the site can have their conversations with her，and Ramona also dances and sings．
3．Kurzweil uses this technology to help people with physical disabilities．One of his ideas is a“seeing machine”．This will be“like a friend that could describe what is going on in the visible world”，he explains．Blind people will use a visual sensor(探测器)which will probably be built into a pair of sunglasses．This sensor will describe to the person everything it sees．
4．Another idea，which is likely to help deaf people，is the“listening machine”．This invention will recognize millions of words and understand any speaker．The listening machine will also be able to translate into other languages，80 even people without hearing problems are likely to be interested in using it．
5．But it is not just about helping people with disabilities．Looking further into the future，Kurzweil sees a time when we will be able to download our entire consciousness onto a computer．This technology probably won&39;t be ready for at least 50 years，but when it arrives，it means our minds will be able to live forever．
