Their house is an amazing 2 And what makes it more impressive(令人印象深刻的) is that Ku— sie designed(设计) and built it all by3 . He used electric motors(电动机) and wheels to make the house rotate. Kusic made the decision because his wife4 that she wanted to be able to see the front yard from the living room. It took a lot of hard work to build the house and even more to make it rotate.

Artificial intelligence( Al) seems to be a hot topic. In which ways has it already changed or will change our lives? A Forbes(福布斯)article explained AI as follows. Finding medicine
By dealing with a lot of messages, Al can find new medicines for different
illnesses. As we all know, AI helped with the development of COVID—19 vaccines(疫苗). It cut time lines from 10 years to 10 months. It also helped find a protein's structure(蛋白质结构). This means scientists can create protein—based medi— cine.
Creating virtual (虚拟的)workplaces
Many people had the experience of working at home because of COVID—19. In the near future, VR,5G and AI technologies will improve the virtual workplaces. Companies can replicate themselves in a digital(数字的)world. Workers will play a virtual role in these companies as they work at home. They will not only work online, but also communicate virtually.

With high—speed chips, 5G and Al, smart objects can become faster and smarter. For example, smart customer controls in a clothes store will know what you like and suggest clothes for you. They will let you"try on" the clothes in a smart mirror and show what colors and sizes they have.
Nigeria is a hot and dry country in Africa where electricity is not available(可获得的)to many fami— lies. Most people grow and sell their own fruit and vegetables. Keeping them fresh in the hot place is a real challenge. Without a fridge, most fresh food goes bad in a couple of days. Throwing away the food means losing money for poor families. Eating the bad food causes serious health problems.
A local teacher, Mohammed Bah Abba, was worried about this problem and decided to solve it. As a boy born into a family of clay pot (陶罐)makers, Mohammed knew that these traditional clay pots could keep water even when the weather was dry. In the 1990s, he used this traditional knowledge to invent a cool— ing system. It worked as a "desert fridge".
Mohammed's cooling system is made up of two pots——a small pot inside a big pot. In the space between the two clay pots, there is wet sand. People put the fruit and vegetables in the small pot, and cover it with a piece of wet cloth. Then they leave the big pot in a dry place. When water in the sand evaporates(蒸发), the temperature in the pots will go down. In this way, the food in the small pot is cool.
Mohammed's" desert fridge" has improved the lives of thousands of people. So in 2001, he won the Rolex Award for Enterprise.
Almost everyone knows the piano, but what do you know about it? You may know it is becoming more and more popular around the world now. Playing . piano has even become part of some people's daily life. Some schools have already offered piano lessons to students. The piano has (bring) them much fun. But how much do you know about (it) history?
Piano has been around for many years, and it was invented an Italian called Bartolomeo Cristofori, who was a crazy lover of keyboard instruments. He was once a maker of (music) instruments. It's said that the ( one) time when the piano was played in a public concert was in 1768. . the piano was brought to China, it was not cheap and only the rich could buy one. But now its price is much ( low) than before. More and more ordinary(普通的) . (customer) can buy one.
Today piano comes in many different styles and designs. What's more, in our country it is(list) as one of the optional (选修的) subjects. Many children begin to learn how to play it at an early age,
In the 1930s, Saudi Arabia was one of the poorest countries in the world, but the discovery(发现)of oil changed this, and now it has become one of the world's richest countries.
America is now the world's biggest producer of oil and gas(燃气). However, it still buys a lot of oil from other countries, because it is the country that uses the most oil in the world as well. In fact, oil provides about one third of the world's energy.
By 2040, the world's energy use will increase about 30%. The clean energy must be used more if humans want to avoid weather change and serious global(全球)warming,
China is the world's largest user of coal(煤) and the second largest user of oil, but it also leads the world in clean energy. One third of the world's new wind power and solar panels(太阳能电池板)are in China, so it makes China become the biggest country which uses clean energy around the world. Also, it sells more electric cars than any other country.
We will run out of oil in the world, so it's necessary for us to turn to clean energy. Of course, the change will face new challenges. For example, it is very expensive to develop clean energy. Another challenge is that the wind and the sun are intermittent(间歇的). So powerful storage batteries(蓄电池)are needed to keep the energy for later use.
To stop global warming, we must develop clean energy and the world needs to work together closely.
