Lesson 31 TEXT A CHALLENGES
Human beings enjoy challenges.
Many of them like physical challenges.
They ask themselves questions like this:
How fast can I run?How high can I climb?
How deep can I dive?How far can I swim?
How long can I hold my breath?
How much can I lift?How high can I jump?
Because people enjoy challenges,
they like to play sports and watch other people play sports.
They like climbing,running,diving,swimming,lifting,jumping,and so on
Every four years,millions of people all over the world
enjoy the international sports competition called the Olympics
People also enjoy the excitement of climbing mountains
or of riding in a boat on a river that is moving very quickly
or of racing in a car around a track.
Why do people enjoy these challenges?
There are probably many reasons.
One is curiosity.
Another is the personal feeling of success or achievement.
And nowadays,for some people,it is a business.
There are challenges that are not physical challenges.
There are social and intellectual challenges,too.

who lived in Italy during the fifteenth century,
enjoyed every possible challenge.
He was an artist and painted the well-known picture,the Mona Lisa
He was an inventor
who invented a device to let people breathe under water
He was a scientist,and he learned a great deal about human anatomy
Another kind of challenge faced the Egyptians
between 4,000 and 5,000 years ago
when they decided to build the first Pyramid.
People are not sure why they built this pyramid,
but it must have been important.
They used six million tons of rock
Four hundred thousand men worked for twenty years to build it
So,for thousands of years,people have accepted challenges.
