Jack is a businessman. His main task is to sell “Living Machines”. He is very interested in clean water. He is also interested in saving money. So it’s natural that he is to be a developer of a small and affordable system (系统) to clean waste water. His “Living Machine” can clean waste water in your home.
The “Living Machine” is a system for cleaning waste water. The waste water goes into a big plastic tank where bacteria (细菌) start to break down the waste. A few days later after it is dealt with, the water is brought into a greenhouse filled with plants and fish. With the help of sunlight, the plants and animals remove more chemicals from the water, making it cleaner. Then the water can be reused for washing or bathing. It can’t be used for drinking and cooking. But the water is clean enough for watering the flowers, washing the dog, or even for bathing or swimming.
The advantage of this technology is that it is affordable and good for the environment. If you have enough homes and businesses use “Living Machines”, you’d better buy it. It can help to use less fresh water. It can help keep the water supply unpolluted, too.
1. Is the “Living Machine” too expensive for people to buy?2. What is this “Living Machine” used for?
3. How does the “Living Machine” work ?
4. Do you think Jack’s invention is perfect? Why or why not?

Our cities are busy and full of people. They’re not smart enough. Wu Yuhang, 13, from Dongguan, Guangdong Province, thinks this is a problem.
“Crossing the street can be dangerous. People cannot keep their eyes off their phones. Drivers cannot see traffic lights if their cars are behind a big truck. I once saw a billboard (广告牌) fall down in a storm. That’s the most terrible,” said Wu. “I’m trying to find smart ways to solve these problems.”
Over the past few years, Wu has invented an assistant system (辅助系统) for traffic lights. It sets LED lights along the road so that drivers can see traffic lights more easily.
To make his inventions, Wu learned programming, building models and so on. But Wu said the most important thing is to find people’s problems in lives.
Wu has a bigger plan for his future—to be a chip (芯片) engineer. “China is still behind the West in computer chíps. And chips are important if we want to build smart cities.”

Scientists at Georgia Tech are working to improve a musical(音乐的) robot called Shimon. Now Shimon not only plays music, but also writes the words to his own songs and sings them.
Shimon is a musical robot. Even back in 2015, it played with other musicians(音乐家) at the Kennedy Center. What Shimon could do was already pretty cool. Shimon is back with lots of new skills. Now it can write the words to its own songs, and sing them. Shimon learned to write the words for the songs the same way it learned to write music— by learning thousands of examples. Scientists train Shimon on the words to 50,000 songs. Singing the songs is another story. To give Shimon a voice(声音), the Georgia Tech team works with scientists at Pompeu Fabra University in Spain. They use AI to make the voice and it sounds very much like a man.
Shimon’s face has also new features(特点). Shimon’s mouth now moves in time as it sings. It also has eyebrows and it allows his face to show more emotion(情感).
Later this spring, the team plans to put out an album(专辑) of about 8—10 of Shimon’s songs. The album will be put on the music streaming service Spotify. There are also plans for Shimon to go on a tour with a band to play and sing its songs live.

Nowadays, there are more and more TV talent shows. They are very popular all over China.
These talent shows give everyone an opportunity （机会）to show off their talents. 3. For some lucky people, these talent shows may make them famous, and can even make them rich. However, there are also many bad sides. First, some young people just imitate （模仿）their favorite stars. They may forget about their own styles. Second, young people spend too much time on such TV shows. They always dream of being a star. 4. So they spend less time on their studies.
In my opinion, these shows are social activities. Young people can take part in these activities to get social experience. But they should know that the chance of becoming famous is very small for most people. They should know that they should work hard at something more important, their school work. In short, you can do what you like, but you should know what is important and what is not.
