    The brain of an insect isn't very big. But insects are somehow still able to make lots of important decisions. Bees, ants and roaches(蟑螂) build hives(巢穴)with thousands of workers doing specialized work. The jobs are done without a head or even a plan. How do insects manage this?

    To solve the mystery, scientists in Belgium spent months building robotic roaches and then putting them among real roaches. The final goal of the research is to find out how the simple behavior of individuals gives rise to a collective decision. The roach is a good starting point for trying to answer the big question because its social system is simple enough for scientists to study.

    The first step was to build robots that real roaches would accept as their own. Although the robotic roaches don't look much like the real thing, they have similarities with them in three key ways: they naturally head toward dark areas, they are influenced by the behavior of other roaches, and even more importantly, they smell like roaches.

    The next step was getting the robotic and real roaches to work together on common tasks. In experiments, the robots would collectively head towards a dark place, copying the behavior of natural roaches. That got the researchers wondering: if you program the robotic roaches to go woward the lighted place, would the real roaches follow, going against their natural instincts.(本能) ?

    They will – it turned out. Many of the real roaches followed the robots to a lighter shelter. But influence turned out to be a two- way street. On occasion, the real roaches were able to override the programming of the robot roaches and get them to turn into dark hiding places. Being social creatures, both the robotic and natural roaches were paying attention to and following the example set by others.

    In theory, it would be possible to create a robot that could influence collective decision-making in humans. To do this, researchers would have to invent a robot that people would accept. Fortunately, the technology isn't there yet.

    Eight years ago, when Kyle Amber was five years old, he came face-to-face with a huge problem: His brother, Ian, ten, was diagnosed with leukemia(白血病). Their parents, Laurie and Henry, were spending much of their1with him in hospital. Kyle often felt alone and 2

    What could a kindergartner do? Not much, it seemed.3, Kyle was determined. He looked around and saw lots of kids being4for cancer and decided he could help them by helping the hospital, which was trying to5money for bone-marrow(骨髓)transplant.

    But how? Since Kyle's grandfather was in the printing business, he6bring decorative cards for Kyle, who7with the idea of selling them8. He made a large sum of momey-$80-for the hospital. His next9was a candy sale at this school, Palmetto Elementary, and it has turned into an annual10.

    And then people in Miami read about his efforts and were inspired to11to donate more money and toys, and things just snowballed.

    Within a year Kyle's idea turned into an official fund-raising organization called Kids That Care Cancer Fund. Today it is one of the12organizations in the country run by kids and13kids. It's hard to estimate just14the group has collected, says Laurie, but it is more than $100,000. As the Mayor of Miami wrote to Kyle, “ Your efforts have made a remarkable15in the lives of many suffering from this disease.”

    Never once has Kyle thought of16, because the smiles of the kids are too important. “ Basically, the entire feeling that you get is very17,” he explains. Helping other kids has taught him to be less18. And there's another thing he learns for sure: “ There is19going to be a time when you're going to have a very hard barrier,” he says. “20you overcome that, you can do anything.”

Man : There you go. I am (awful)hungry, Is the coffee shop still open?

Hotel Clerk: Yes, it is until nine o'clock. If you want anything after that, there are a couple of machines (sell) soft drinks, chocolate bars, and so on.

Man : Thank you. By way, is there a television in the room?

Man : Oh, that's great.

Hotel Clerk:Well, here is your key. you need anything else, please call me.

Man : Ok. Thanks again.
