    David decided to use a different code in his answer to Sam. This time, he was putting A instead of B,
B instead of C, and so on. His message to Sam shown on the right was very short. Can you understand?
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
B C D E F G H I J K L M N O P Q R S T U V W X Y Z A
    Sam guessed David's code, and he replied: ZESDQ, RBGNNK. When David's little sister saw the message,
she felt puzzled. She couldn't read it at all. But David was very happy that his sister couldn't read his message!
     Lots of people use codes to send secret messages. In a war, secrets are very important so soldiers often
send each other messages in code. Nowadays, we can use computers to make and break difficult codes. Even
before computers, people invented other machines to do this. 
    Here's a famous machine that Germans used in the Second World War (1941-1945). It's called the Enigma
Machine. The machines were very big, heavy and expensive. Every day they changed the codes automatically,
and this made it almost impossible for anyone to break the codes. The person sending a message had one
machine, and the person receiving the message had another.

     Who was Leonardo da Vinci? You may answer without thinking: "He is the painter of Mona Lisa."
What else do you know about him? Da Vinci was more than just a great artist in history. He's also famous
as a scientist and an inventor.
     Recently, the Grand Rapids Public Museum in the US had an exhibition to introduce this great talent.
In one of the shows, named "Leonardo da Vinci's Machines in Motion", visitors could see and touch 30
full-size machines built according to his sketches-including a crane (起重機(jī)) and a robot!
     Leonardo da Vinci was born to a rich family in Florence, Italy, in 1452. From childhood, Leonardo was
given a good education and he showed talent at painting. By the age of 26, Da Vinci had already become a
famous painter.
     However, he showed that he had multiple talents in 1482 when he began to work for the Duke of Milan
as a chief engineer. In the duke's military factories, Da Vinci developed an interest in war weapons.
     He designed many important machines, including helicopters and parachutes. He also drew and wrote
about an armored car, which could carry eight men inside and allow them to fire weapons through holes
in its walls. Da Vinci's idea led to the mod- ern tank. Though Da Vinci never built many of the inventions
he designed, some of the things he imagined in the late 1400s are in use today.
     As a scientist, Da Vinci was fascinated with the human body. He spent a whole year cutting up dead
bodies in hospitals to learn about human anatomy (解剖). He made more than 200 drawings of bodies.
     Amazingly, Da Vinci wrote backward, so the easiest way to read his notes was to hold them up to a
mirror!

body, and the left controls the right side of the body. So right-handed people have a strong left brain, and
left-handed people have a strong right brain.

When you memorize the spelling of words, or when you put things in order, you use your left side.

arc many exceptions (例外).  Some right-handers have a strong right- brain, and some left brain have a
strong left brain.
