2 . The human brain's power could compete with any machine. And now a group of scientists from across Europe are trying to build one using the world's most p    1     computer.

Our brains have 100 billion neurons Each one performs billions of ‘calculations’ second   s    2     to a desktop computer.

So the brain computer will need to be able to do a billion calculations.

Finding a way to power the supercomputer will be one of the Scientists' major challenges. They hope to c    3     it within 12 years.

Group leader, Professor Henry Markram, said, “The billions of interconnected neurons make it hard for us to truly understand how the brain works. Simulating it will make it much e    4     allowing us to operate and measure any aspect of the brain.”

The brain will be built in facility in Germany. It will have thousands of 3D images, so scientists can “fly” around different areas and w    5     how they communicate with each other.

If the “brain” works, it will help scientists understand brain diseases such as Parkinson's, and know more about how we think and make d    6    .

There are concerns about the consequences of the computers which can think for themselves. But Professor Markram said “This is one of the t    7     great challengers for humans. We need to understand earth, space and the brain. We need to understand what makes us human.”

He told her, ＂From now on, print on white paper instead of blue!＂

10 . The police find most criminals because somebody tells them who the criminals are. They find other criminals by using science and their computers. When there is a bank robbery, the police first look t    1     their computers for the names of the bank robbers that they know about. Then they go and talk to any of these robbers who are not in p    2    . They ask them where they were when the robbery happened. If any of these people cannot give a good a    3    , the police will often use science to find out if one of them is the robber.

Many criminals leave something of themselves at the places of the c    4     like a fingerprint or a hair. Or they take something away on their s    5     or clothes, like dirt or animal hair. If they leave behind some of their b    6     or their hair or a piece of skin, it will have their DNA inside it.

Everyone’s DNA is different and their f    7     are also different. So, if a criminal cuts himself during a robbery or leaves his hair, or e    8     a small piece of skin, scientists can find out what his DNA is. The police can then ask the s    9     to give them his hair or some blood and see w    10     it has the same DNA. Many criminals are in prison today because of this kind of evidences.
