Matt Mason has seen the future - and it's fun. Mason likes thinking about how machines can make our lives easier by doing the work we hate, such as cleaning. He shows a hard floor cleaning system that's built into the wall; it will blow dirt to a part of the room where it will be collected by a vacuum. Then the system will drop some cleaner on the floor and an arm will mop it up.

When it comes to the kitchen, Bruce Beihoff, another expert at Whirlpool, is sure that in a few years, robots will be doing most of the boring work, freeing us to relax. "More than just fun. Future kitchens will be environmentally friendly, "he says." A new system will be built in the house which can recycle energy lost from your kitchen to make the whole home warm.

"The fridge will be the centre of the home," says Daniel Lee, a market expert. The fridge will have a touch screen where you can watch TV, surf the Internet, check your email, keep a shopping list and order vegetables. Lee says, "Your fridge is the first place you go in the morning and the last place at night.

Ever wonder why a 1. 9- metre man and a 1. 6-metre woman have to cook meals on counters of the same height? "The height was decided over 50 years ago, according to the height of ordinary women," says Jane Langmuir, an expert of cooking machines." But times have changed. We are thinking about making a new counter where you press a button and it moves to whatever height you want.

He looked through them but he still didn't know what to write. When he wanted to charge his phone, he saw the USB and then he had an idea. He decided to write something about it.

Then he visited some (网站) and found plenty of information. He (存储) it in his memory card. Here is some of the information:

In the late 1990s, the USB was invented as a system of sending information from one place to another at a very fast speed. Its inventor Ajay Bhatt was worried about the different forms of (连接) that a PC had and looked for a simpler way of connecting different parts of a computer. He tried to set up a connection system for all the (电子的) devices. So the USB resulted. The USB is (有影响力的). A single port (端口) can control up to 128 devices at a time.

Do you like handicraft (手工艺)? For Yang Changqin, a 31-year-old intangible. cultural heritage inheritor (非物质文化遗产继承人)of Chishui bamboo-weaving (竹编), the handicraft has not only changed her life, but also helped many people in Chishui to get rid of poverty (摆脱贫穷).

Yang was born in a poor family in Guizhou in 1990. Her father died when she was young. After graduating from middle school, she started to work and support her family. During the time, she did many different jobs, including being a saleswoman, a waitress and a cook. After collecting some money , she returned back to school again.

In 2007, when Yang was about to complete her course, as one of the school's top students, she got a chance to join nine other classmates on a six- month trip to learn the bamboo-weaving craft in Chishui."At first I often cut my fingers, making it too hurt to hold chopsticks at mealtime. But I also started to be interested in the beautiful handicraft," Yang says. Back home, when she finished her course, instead of finding a job as a teacher .Yang made the decision to return to Chishui to continue learning the craft. "I often felt pity for the loss of traditional crafts and the culture behind them, so I wanted to inherit this craft and call on more young people to learn it."

In 2012, Yang started a business to sell bamboo-woven products like tea sets and bags both online and offline. "If you sell the bamboo, you can get 6 yuan at most, but if you sell a bamboo- woven product, you can get several hundred yuan or even a thousand," says Yang.

Her products are sold all over China, and even abroad. In 2019, her company s sales even reached 6 million yuan. "My company is named Qianshou, which means' joining hands'. I want to take more people's hands and guide them to get into the bamboo- weaving industry," says Yang. Growing up in a single-parent family, Yang understands the difficulty of left- behind children and the elderly. She has taught many local women to weave bamboo. They now produce bamboo products for Yang from home, where they are able to take care of the family instead of moving to far areas to find work. So far, she has helped more than 100 local women in this way.

Man invented a lot of sports equipment. The first one was the ball.

Thousands of years ago, in Egypt, the children's favourite game was throwing stones. But a badly thrown stone could hurt a child. Looking for something less dangerous to throw, the people in Egypt made the first balls.

At first, they used tree leaves to make balls. They used vines(藤) to keep the leaves together. Later they began to use pieces of animal skin and fill them with some light things. These balls were much better than the old ones.

Before long they invented a lot of ball games. Each had its own rules. They began to play these ball games according to the rules. They thought that ball playing was one of the best ways to teach the young people to be brave and strong.

The building is about one hundred metres  .
