We know many great inventions which have changed the world. Have you ever had a wonderful idea and thought it would make a great invention, but didn't know what to do next? 【小题1】 They will help you make your dreams come true and become a famous inventor.

The first thing that you should do is to do some research on the Internet to see if anyone else has invented it. If not, you should search through the US Patent (专利) information to see if a patent was ever created for your type of invention. 【小题2】.

The easiest thing to do is working with a company that can help you to make your dreams a reality. It can help you present your ideas and get your product to the right companies. One company that is very reputable (声誉好的) is "Lambert and Lambert in Minnesota". 【小题3】 If they think your product is marketable (有销路的), they will help you to get it to the right company.

Call the company and make an appointment. You will want to bring in a model of your invention and a complete description of your ideas. 【小题4】 Then when you meet with them, you can present it and they will tell you how marketable it is. If they decide to help you, they will work to present it to different companies and help you to go to the next step.

Once your invention has been sold to a large company, get ready to get the benefits of becoming the next great inventor.

【小题5】 But the benefits are worth the wait.

Sleeping. Eating. Sleeping. Eating again. Life in a pigpen (猪圈) is boring. Nothing ever changes. Sometimes, I can’t help thinking: What do I live for? “Pigs produce pork. Just eat as much as you can!” my roommates told me. “It is sad, but you can’t change it, can you?”

But last month, I heard the pigpen owner talking on the phone about something unusual. Some American doctors saved a very sick man by replacing his heart with a pig’s. This had never successfully been done before.

My owner sounded excited. I know why. His elderly uncle had been in the hospital for weeks because of a serious heart problem. A heart transplant (移植), the doctors said, was perhaps the best choice for him. However, ________. Most heart patients have to wait years before they are able to receive a transplant. Some of them die during this long and painful process. The successful operation in America means that in the future, people can depend on us pigs for healthy hearts. We are easy to raise, and we grow quickly.

Sadly, I am just an ordinary pig. I’m not able to save my owner’s uncle. But some of my kids will probably be growing up in a special lab. They will be living as lifesavers, instead of pork providers. Perhaps my owner was talking to scientists about cooperation (合作) that day. Perhaps life in the pigpen will finally be a bit different.

The well-known “new great inventions” of modern China have made our daily lives more convenient.

High-speed trains

China created its first high-speed railway line in 2008. Since then, the number of passenger trips has grown by over 30 percent every year. By 2016, more than 5 billion trips had been taken on the trains. By 2020, one-fifth of the country’s 150000-km railway network will be used by the trains. This network will link more than 80 percent of major cities across China.

Mobile payment

Mobile payment is turning China into a “cashless society”. Instead of paying by cash(现金) customers now pay for their goods and some kinds of bills simply by typing a short password into the Alipay(支付宝) or Wechat Pay app on their mobile phone.

Shared bikes

China has surprised the world with how quickly shared bikes are widely used. Nowadays, bike users can simply pick up or park the bike on the street through GPS and smart phone apps. China's two leading bike-sharing companies, Mobike and Ofo, have been opening their overseas markets in Singapore, the UK and the United States.

Online shopping

With around 751 million Internet users, China has been the world's largest and fastest growing online shopping market. Because of lower costs and fewer licensing requirements(执照要求), it’s easier for sellers to open an online shop in China. In 2016, more than 20 million jobs of rural areas were created, with over 8.1 million running their own online shops.
