Imagine having a bedroom that interacts with you. If you"re sad, it will arrange for some of your friends
to come over to cheer you up. If you"re happy, it might respond by playing your favorite game with you.
Does it sound like something out of a science-fiction movie? Well, it"s really something out of the Georgia
Institute of Technology. Irfan Essa works at the computer lab there. He has developed a computer system
that can look at you and recognize your mood. He calls it the "expression recognition system." Essa says, "We
are trying to get computers to act like a human brain. But the human brain is not like one computer, it is like
many working together."
In Essa"s system, many computers work together. First, a camera in the bedroom takes a picture of your
face. The camera feeds the image to a computer. In the computer"s memory, there are pictures showing how
the muscles of your face move when you are in different moods. For example, cheek muscles move in one
way when you are happy and smiling and in another way when you are nervous and tense. The computer
compares your picture to the face-muscle images stored in its memory. It tries to find the best match.
That"s how it figures out your mood! Then the computer sends messages to other computers in the system.
If you look happy, a computer may put on lively music. If you look tired and discouraged, a different
computer may turn on the TV for you.
How could the "expression recognition system" help us in important ways? Essa thinks that the system
can help us create computers that are better teachers. Many people learn new skills through computer
programs. "When I teach, I look at people"s faces," Essa explains. "If my students look confused, I know
they didn"t understand. With this technology, a computer canal-so know if a student is learning."
Today, this new technology can be found only in labs, but Essa predicts we"ll see it out of the lab in a
few years. So get ready. One day, you might walk into a room that will soon become your best friend. |

Each year Ben is glad when school is closed on Martin Luther King Jr. Day. Ben knows that this day
honors an important man, but Ben does not feel connected to him. However, the small-world theory (理论)
connects Ben to Dr. King. Ben"s mom (0) has a close friend, Amy (1). Amy"s uncle, Mark (2), once met and
spoke to John Carter (3), the son of President Jimmy Carter (4). Jimmy Carter knew Dr. King (5). In a way,
Ben is only "five people a-way" from Martin Luther King Jr.
The small-world theory says that everyone in the world is connected through a short chain (链条) of
people they know. Another name of this chain is degrees of separation. Each degree is a step that separates
a person from someone he or she does not know. There are zero degrees of separation between a person
and the people he or she knows directly. This means that there are zero degrees between Ben and his mom.
There is one degree of separation when just one person separates someone from a person he or she does not
know. Ben knows his mom, but he hasn"t met her close friend Amy. Therefore, Ben is one degree away from
Amy. As the chain continues. Amy"s uncle, Mark, is two degrees. John Carter is three degrees, and his father
is four degrees. Dr. King is five degrees away from Ben. The theory says that there are no more than six
degrees of separation between any two people in the world.
The small-world theory has a lot to do with math. The theory assumes (假定) that each per-son knows
100 people. Each one of those 100 people knows 50 different people. Each of those 50 people knows another
50 people, and so on. When someone continues the calculation" to six degrees, it is like this: 100 × 50 × 50 ×
50 × 50 × 50 = 31.25 × 109. This number is greater than 31 billion (a billion=a thousand million). There are
over 6 billion people in the world. These numbers show it is possible that six degrees of separation could
include everyone in the world.
Does the small-world theory work? No one has ever proved it. Maybe the theory just invites people to
think a little more about their places in the world. |

| 4. We can learn from the article that ______. |

History is the story of us, human beings. Everyone who has lived and everything that has happened are
part of history. But history is not only what happened in the past. The word also means the study of the past,
through old written records and other kinds of facts.
Why do we study history? One reason is that we enjoy it. A good story is even better if it is true, and
history is full of good stories, though they can be terrible too. A more serious reason is to understand ourselves
and the world we live in. To understand events happening now, we need to know their causes. We cannot
understand the present if we know nothing about the past. History helps to explain why things are the way they
are.
Of course, history books cannot tell us everything about the past, not even everything that is recorded. A
history of the world has to pick out the people and events that changed the world.
Since ancient times, great civilizations have appeared in different countries and regions. Usually, only three
or four existed at the same time. While they lasted, they changed the lives not only of their own people, but of
their neighbors too.

"Mother tells me that the most important is to study, and she almost never gives me any housework to do,
though I really want some," said Wang, a middle school student in Guangzhou, capital of South China"s
Guangdong Province.
A report says that most of Guangzhou teenagers (青少年) want to do more housework, but their parents
usually do not think so. According to (根据) the report, 37% of the teenagers do housework less than half an
hour every day; 39.4% of them from half an hour to one hour; 11.5% one to two hours; 5.6% over two hours;
and 6.2% just have"no" housework to do.
"Most of my time after school should be spent on my homework, and I don"t have time to play. Even on
weekends, my parents ask me to stay at home to study. I can"t go to see a film, watch TV or play with other
children. My parents never say to me about anything to do with the housework. Sometimes I feel I have the
duty to do something to help my parents, but they just get everything done for me," said Yang Ming, a sixteen-
year-old student.
Experts say this won"t change much unless the College Entrance Examination, which adds much pressure (压力) on high school students, is changed. |
