1 Easton LaChappelle, a 14-year-old student, stood beside his work
at a science fair. It was a robotic arm. He built it out of plastic
blocks and fishing line.
2 "Hello," said a girl with an artificial arm, as she shook hands with
Easton's work.
3 This was the first time Easton met Jenny, a girl with a special
condition. She was born without an arm. Her artificial arm was
just a simple hook, but it cost $80,000. What's worse, children like
her grow quickly and need new arms all the time.
36 UNIT3
4 "lt blew me away! I built my arm for only $300," thought Easton. "l
must lend a hand to people like her."
s After the fair, Easton's room became a lab. He stayed there all day.
He always tried to improve his work. For his 16th birthday, Easton
got a 3-D printer. And with it, he invented an artificial arm. It was
able to move with brain signals of the user. But it wasn't good
enough yet: the arm weighed 3.6 kilograms. It was too heavy for a
child.
6 Easton kept working on it. He enjoyed fixing problems one after
another. And finally he hit on success at age 23. His design only
weighed 0.5 kilograms and cost around $500!
7 Easton's invention has helped many children. He didn't want to
make money from it. He decided to post his design online... for
free! People can download the design and make an artificial arm
with their own 3-D printers!

Not every invention is created on purpose. Sometimes it's completely by accident! For
example, in 1928, Dr Alexander Fleming forgot to clean his lab before going on a holiday.
Later, he discovered penicillin from an uncleaned Petri dish. lt's now one of the most used
medicines in the world!

Reading for uuriting
O Look at the pictures and answer the questions.
Use the words and expressions to help you.
1 Who invented them
2 How would you describe the inventors
curlous new discoveries do research
brave ploneer scientist discover
O Read the passage and check your answers.
1 Albert Einstein once said, "l have no special talents. I am only
passionately curious." The greatest inventions in history would be
impossible without curiosity.
2 Curiosity can bring new discoveries. Benjamin Franklin is a great
example. He was drawn to electricity and had a deep curiosity
about its nature. He did lots of research to try to understand it.
For example, he flew a kite during a storm. His curiosity led him
to invent the lightning rod. This invention protects buildings from
lightning.
3 Curiosity can also make people brave. Just look at Wan Hu, the
Ming Dynasty pioneer of space exploration.
He was so curious about space that he
invented a "flying chair"! He lost his life
while testing this invention. Despite the

Ｊ
failure, his curiosity gave future explorers ideas. People learnt
from his example, and created safer ways to explore space.
a But curiosity is more than just taking risks. It also drives people
towards certain goals. Zhang Heng, a Chinese scientist and
inventor, was curious about the world: how did everything in
the world move He spent years studying the sky and the earth.
Finally, he drew China's first star map, and invented the first
earthquake detector. His curiosity continues to influence scientists
today.
5 As Jacques Cousteau said, "What is a scientist after all It is a
curious man looking through a keyhole, the keyhole of nature,
trying to know what's going on." Curiosity is the key. It opens one
door after another for us to discover a new world.
