Creative and New Ideas from Teenagers

Teenagers are known for being creative and full of new ideas. Let's have a look at these teenage inventions that might change the world.

Banana leaves usually go bad in two or three days. Richard, a teenager from India, used UV to make the leaves stay fresh for a year. Richard thinks that one day the leaves will be used for making plates, cups and other things.

David, an American teenager, built an earthworm (蚯蚓) robot. It is able to go into the smallest places, where humans or dogs can't go. It will be finding people in a fire or an earthquake.

Sara, a 14-year-old girl, from South Africa, found it tiring and boring to hand wash clothes in the nearby river. She reused some bicycle parts and created a washing machine that saves time, energy and keeps people fit at the same time.

Once there was a poor old man called Colonel Harland Sanders. He lived in a small house and had an old car. He was living off the social security(社會保障金). In his sixties, he thought things had to change(改變), so he thought about what he had to do. His friends liked his chicken recipe(食譜) very much. He thought that it might help him to make a change.

He left Kentucky and traveled to different states. He told restaurant owners that he had a mouth-watering chicken recipe and asked them if they would like to buy it. He would like to give the recipe to them for free, just asking for a small percentage(提成) in return. Sounds like a good idea, right?

Unluckily, those restaurant owners didn’t think so. As a result, the old man heard “NO” over 1,000 times. Even after all of those rejections(拒絕), he didn’t give up. He believed his chicken recipe was something special. He heard “NO” 1,009 times before he heard his first yes.

With that one success, Colonel Harland Sanders changed the way that Americans ate chicken. Kentucky Fried Chicken, also known as KFC, was born. Now it is the world’s second largest restaurant chain(連鎖).

Never give up and always believe in yourself. After all, nothing is impossible if you put your heart into it.

1.What does the underlined word “it” refer(指) to?

A.The small house. B.The old car.

2.Why did Colonel Harland Sanders travel to different states?

A.To sell his chicken. B.To open a restaurant.

C.To sell his chicken recipe. D.To enjoy delicious chicken.

3.What happened after Colonel Harland Sanders failed(失敗) 1,000 times?

A.He heard his first yes. B.He gave up his idea of making a change.

C.He kept on trying in other restaurants. D.He changed the way that Americans ate chicken.

4.What does the passage mainly tell us?
