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.

Well, inventing means creating something “new”, but the idea could come from something that already exists*. 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* that make invention possible. Take Mozart, for example. He was born with an endowment 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*.

1. got the idea for building a “flying machine” from watching birds.

A. Mozart B. George Nissen

C. Louis Braille D. The Wright Brothers

2.The underlined word “endowment” probably means “ ”.

A. 态度 B. 品质 C. 天赋 D. 能量

3.According to the passage, which of the following is right?

A. Anybody can do inventing.

B. Inventors are born, not made.

B. 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

阅读下面短文根据内容选择最佳答案。

As a child, Alain Robert was afraid of high places. One day, when he was 12, he went back home from school. At the front door of his building, he looked for his keys. He didn’t have them. It was 3:30 and his parents worked until 6:00 pm. Alain looked at his apartment on the eighth floor. He saw an open window. He closed his eyes and imagined himself climbing the building. When he opened his eyes, he told himself, “I can do it.” Fifteen minutes later, he was in his house and his fear of high places was gone.

Today, Alain still climbs building. In 2003, he climbs a building in London dressed as Spiderman to advertise(为…做广告) the movie. In 2004, he climbed a building Taipei 101 (one of the tallest buildings in the world). To reach the top of a building, Alain uses only his hands and special shoes. He has no rope or other safety tools.

Alain climbs as a hobby. He also does it to make money for charity (for poor children and the homeless). When he climbs, he wants to send a message to people. If you have a dream or something you really want to do, it can become real. But you must be brave and keep trying. If something bad happens, don’t give up. Close your eyes and tell yourself, “I can do it.”
