How to Invent a Product

1.

It's unnecessary to think of something that no one has ever thought of before. Just ask yourself what exactly you are trying to improve or solve? If you want to build a better dust mop (拖把),how will it be better? What interesting or important part does it have? What could you do differently?

2.

Try coming up with 15 solutions in a minute, no matter how crazy. Or choose one of the solutions and ask how is that like my idea? "How and why does it work?" "When, where and how is it used?" "How is it described?" Let your questions and imagination come up with new ideas or find a different way of looking at a problem

3.

Visit stores that offer products similar to what yours will do and even go as far as to ask store workers for products they might sell with a similar purpose. If you have a name for your product created, search this to find out whether it is already being used.

4.

This is often the longest part of inventing! Thomas Edison's lab tested more than 6,000 different materials for light bulbs before they came up with one that worked. Make the model until it works the way you want. Sometimes you might discover an entirely different idea.

5.

When you think you've got everything ready, it's time to make a working model of your invention --- a prototype. This is what you'll use to show people what it will look like and how it will work. You can use this prototype to show and introduce to the people who might have interest.

A.Research your invention.

B.Brainstorm

C.Ask for advice.

D.Find a problem worth solving.

E.Make your invention to a reality.

F.Build, test, rebuild, repeat.

Have you ever taken photos by using mobile phones with selfie sticks(自拍杆)? This new invention is a small, useful and cleverly-designed tool.

However, a pair of US artists from New Mexico, Arie Snee and Justin Crowe believe they have invented a better one and they call it “selfie arm”. For better or worse, they have taken the world by storm. It makes those people in the pictures seem to be holding hands with a loved one.

The pair say it offers a far better experience than using a straight stick. The selfie arm makes people feel they are not alone when they take photos. It seems that they are together with their friends. They think their invention solves the main problem that the selfie stick has —people look alone while they are taking pictures of themselves with great interests. The product, at present, just an art project and a model, conveniently provides you a welcoming arm. And better yet in the future, it’ll talk in a friendly way and never get angry or upset. The pair say they are fascinated by these new ideas.

The “selfie arm” is made of fiberglass(玻璃纤维). It is lightweight and easy-taking.

The project that they work on shows the growing selfie stick phenomenon(现象) directly and the increasing need for narcissism(自恋) and Internet agreement.

1.The selfie arm is _____________________.

A. the latest mobile phone B. lightweight and easy-taking

C. cleverly-designed but useless D. a useful digital camera

A. Mexico B. New Zealand C. America D. Not mentioned

4.___________ will make people feel they are alone while taking photos.

九年级英语单选题中等难度题查看答案及解析

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

C. How to help blind people　　　　　　 D. Be an inventor
