Human beings have used tools for a very long time. In some parts of the world you can still find tools that people used more than two million years ago. They made these tools by hitting one stone against another. In this way, they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood. Human beings needed to use tools because they did not have sharp teeth like other meat eating animals, such as lions and tigers. Tools helped people to get food more easily.

Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and machines. The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to success of mankind.

Since 1960 a new kind of tool has appeared. This is the silicon chip -- a little chip of silicon crystal. It is smaller than a finger nail, but it can store more than a million "bits" of information. It is an electronic brain. Every year these chips get cleverer, but their size gets smaller, and their cost gets less. They are used in watches, calculators and intelligent machines that we can use in many ways. In the future we will not need to work with tools in the old way. Machines will do everything for us. They will even talk and play games with us. People will have plenty of spare time. But what will they do with it?

Human beings used stone chips for more than two million years, but human life changed very little in that time. We have used silicon chips for only a few years, but life is changing faster every day. What will life be like twenty years from now? What will the world be like two million years

Honesty is the best policy, as the English saying goes. Unfortunately, honesty often leaves us when no one is watching, British psychologists reported last week.

Researchers at UK’s Newcastle University set up an experiment in their psychology department’s coffee room.

They set a kettle, with tea, coffee and milk on the counter and hung up a sign listing the price for drinks. People helping themselves to a cup of tea were supposed to put a few cents in the box nearby.

The scientists hung a poster above the money box, and changed each week between pictures of gazing eyes and pictures of flowers. The researchers found that staff paid 2.76 times more for their drinks when the image of the eyes was hung.

“We were shocked by the size of the effect,” said Gilbert Roberts, one of the researchers.

Eyes are known to be a powerful perceptual (知觉的) signal for humans, scientists say.

“Even though the eyes were not real, they still seemed to make people behave more honestly,” said Melissa Bateson, a behavioral biologist and leader of the study.

Researchers believe the effect throws light on our evolutionary past. It may arise from behavioral characteristics that developed when early humans formed social groups to strengthen their chances of survival. For social groups to work, individuals had to co-operate, rather than act selfishly. “There’s an argument that if nobody is watching us, it is in our interests to behave selfishly. But when we’re being watched we should behave better. So people see us as co-operative and behave the same way towards us,” Bateson said.

The new finding indicates that people have a striking response to eyes. That might be because eyes and faces send a strong biological signal we have evolved to respond to, Bateson said.

The finding could be put to practical use. For example, images of eyes could ensure ticket sales on public transport and improve surveillance(监视) systems to deter anti-social behavior.
