It's very early in the morning and I'm sitting outside. It's also very cold and dark. With me is Jim Nightingale, and he is the reason I'm up so early. He passes me a hot cup of coffee. "Not long to wait now," he says. I hope he's right.
After a few minutes there is a very weak light in the east, and then I hear a bird singing. It sings very loud and very clear. "That's the robin(知更鳥)," says Jim. A few more birds start singing with the robin and Jim knows the names of them too. Half an hour later, there are more and more birds singing, and it's very loud! Suddenly, all around us the air is full of the sound of birdsong. This is the dawn chorus(晨鳴), and it's beautiful.
"Wow, this is amazing!" I tell Jim, who is smiling. "Is there a dawn chorus every morning?"
"Birds can sing any time of the year but the best time is the end of winter and during the spring. This is when the birds sing most."
"Really? So, why do they sing?" I ask.
"Well, there are two reasons," explains Jim. "Most of the songbirds who sing are males. They want to find a female(雌性)so they sing to show how strong they are. The females listen and choose the best singer! The birds also sing to tell other males to go away. They need their own area; they don't like sharing with another male."
I listen to the birds; the songs seem too much to me. "Do the birds sing a special song in the morning?"
"That's a good question," replied Jim. "The successful birds have many kinds of calls and songs. Sometimes they copy the songs of other birds. This makes it sound like there are many birds in that place already and other males stay away. Also the female likes songs with different notes. Some birds, for example the European wren, have songs that contain over 700 different notes per minute!"
So, how does Jim know so much about birds? Well, he works as a volunteer for the Royal Society for the Protection of Birds. He is trying to help the birds live in the modern world. "More and more of the birds' habitat disappears every year. The sparrow, for example, was a very common bird in the UK, now it's in danger."
By now the sun is up and the birds are quiet. It's light so they can start looking for food, they need a big breakfast after all that singing.

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 can also 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.
1. Can the new computer system look at you and recognize your mood?
2. What happens first in the bedroom in Essa’s system?
3. Will the computer put on lively music or turn on the TV if you look happy?
4. How does the “expression recognition system” make computers better teachers?
5. What will future rooms be like?
