Scientists at the University of Michigan have built a robot called MABEL. MABEL is able to run at a speed of 6.8 mph. This is a world record for a machine with two legs.

It took the researchers three years to get MABEL up and run to her top speed. There are still some problems, but she is thought of a huge step forward for robot-kind. The makers of the robot say that science and technology can help people. Jonathan Hurst is a scientist from Oregon State University. He says scientists have done research into what MABEL can do in the future. They think that walking robots can help people who have something wrong with their legs walk again, or help people do things like a superman.        

Professor Jessy Crizzle, from the University of Michigan, also points that how useful human-like robots can be. “If you would like to send robots to search for people when a house is on fire, they can go up and down the stairs, step over the baby’s toys on the floor and go in places where wheels and tracks can not go.”

There will be a kind of new cars in the future. The car is as small as a bike. But it can carry two people in it. People will like this kind of small cars better than the big ones. Everybody can drive the car easily, just like riding a bike. Even children and old people can drive them to schools or parks.

The little cars of the future will cost less money to buy and to drive. These little cars can go only 65 kilometers an hour, so driving will be safer. The cars of the future will be fine for going around the city, but they will not be useful for a long trip.

This kind of cars can save a lot of gas. They will go 450 kilometers, and then they have to stop for more gas. They are nice cars, aren’t they?

The way of Chinese people’s life has been changed by “New Four Great Inventions”. What are “New Four Great Inventions”? They are High-speed rail, Shared bike, Online shopping and Alipay.

High-speed rail makes it easy to travel thousands of miles a day. Today China has the best rail transit (运输) technology, the China’s daily average of 4,000 trains, sending about 4.6 million passengers.

Shared bike makes short walks faster and more convenient, and carbon missions are reduced, which is friendly to the environment. You can download the APP, pay some money, and then you can use bicycles everywhere in the street.

Online shopping is to pay money online. With online shopping, you don’t need to go out to find the needs for living. Purchases can be sent home. It lets Internet users enjoy “shopping carnival(狂欢节)” every day.

Alipay is a software which can replace cash payment. By scanning(扫描) the “QR code”, Alipay wants to gradually replace cash payments. On November 11, 2018, both the mobile payment account and the transaction reached 213. 5 billion.

There is no doubt that China has already used its own power of “New Four Great Inventions” to become the great powerful technological country, showing the power of China once again.
