The biggest secret about inventing is that anybody can do it! Perhaps this sounds crazy, but it's true. Maybe you have the wrong idea about inventing, so read on to discover the truth.
Wrong idea No. 1: An invention has to be something completely new.
Inventing means creating something "new", but the idea could come from something that already exists(存在). The Wright brothers, for example, got the idea for building a "flying machine" from watching birds.
Wrong idea No. 2: Inventors are born, not made.
There are a lot of factors(因素) that make invention possible. Take Mazart, for example. He was born with a talent for musical composition. But other factors were also important for his creativity. His father was a music teacher, and Mozart practiced for hours every day, from the time he was four years old. Thomas Edison said that being an inventor was "99% hard work and 1% inspiration"!
Very successful creators don't give up when they get something wrong. As one inventor said, "A failure is the right answer to the wrong question."
Wrong idea No. 3: Inventors are always old people.
Don't believe that you can't invent something when you are young. Here are two examples of young inventors: Louis Braille went blind when he was a child. When he was fifteen, he invented a system of reading and writing for blind people that is still used in most countries today.
As a young man, George Nissen was watching some artists performing in a show. He watched how they fell into the safety net and then jumped back up again. This gave him an idea, and he invented the trampoline(蹦床).
( ) 1. ? got the idea for building a "flying machine" from watching birds.
A. Mazart B. George Nissen
C. Louis Braille D. The Wright brothers
( ) 2. The underlined word "talent" probably means ?.
A. 态度 B. 品质 C. 天赋 D. 能量
( ) 3. Which of the following is the writer's opinion?
A. Anybody can do inventing.
B. Inventors are born, not made.
C. Inventors are always old people.
D. An invention has to be something completely new.
( ) 4. The best title for the passage would be ?.
A. How to Perform in a Show B. Be a Composer
C. How to Help Blind People D. Be an Inventor
