A Swiss radio station called Couleur 3 recently did an experiment on air, testing robot-created content and voicing.

During the 13-hour experiment, listeners heard the cloned voices of five human presenters. The station’s programming also included music created by AI. The program told listeners about the experiment every 20 minutes like this, “AI is taking your favorite radio by storm,” a voice said. “AI is here to surprise and shake you. And for that matter, this text was also written by a robot.”

The Swiss station’s director, Multone, said that Couleur 3 was able to do the experiment because it is already known for doing unusual things. He thought it as a lesson on how to live with AI. “I think if we become ostriches...we put our heads in the sand and say, ‘Multone, there’s a new technology! We’re all going to die!’ then yeah, we’re going to die because it (AI) is coming, whether we like it or not. We want to know it well so we can then put limits on it.”

Music that aired during the experiment was mostly created by AI methods. Besides, human-sounding robot voices provided false short news stories which were too imaginative to be believed. These included a story about one-month ban on spaceship flights over Geneva because of noise complaints. Another talked about the opening of the first underwater restaurant in Lake Zurich, while another told that ________.

There was a lot of discussion about whether to go on the experiment. He said he would stop the project if his team was not fully supportive. The station said it received hundreds of messages, with some supporting and others going against it. One person disliked the unfunny jokes. One considered the project a waste of time for a station that gets money from the government.

Multone said about 90 percent of listener reactions suggested the experiment was a good idea. But at the same time, many listeners pointed, “You can feel these are robots, and there are fewer surprises, less personality.”

My choice for a modern wonder of the world is the Simplon Tunnel in Switzerland. It’s actually two tunnels-railway tracks run through both of them.

They’re each almost twenty kilometers long. They’re not the longest tunnels in the world now, but they were when they were built, back in the beginning of the 20th century. The first one was started in 1898 and opened in 1906.The other one was started in 1912 and was opened in 1921, so each one was taken about eight years to build. The first tunnel was built by drilling in both directions-when the two drill-holes met in 1905, they were only two centimeters out of alignment. In those days, that was a tremendous achievement.

While it was being built, about 3,000 people worked on the construction every day. The working conditions weren’t very good-for example, it was often very hot inside and more than sixty people died during the building of the tunnel.

The tunnel joins Switzerland and Italy, and it has helped to make the travel between the two countries a lot easier than it was before. Now, people can put their car on the train and take it through the tunnel, so they don’t have to drive over the Simplon Pass.

I think this was a great thing to build all those years ago and it has made a big difference to the whole of that part of Europe.

What is it in the picture? Is it an eggplant? In fact it’s a tomato, a purple tomato. The special kind of tomato was created by making changes to its DNA. Besides the unusual color, what’s really special about the tomato is that it has very high levels of antioxidants.

Antioxidants are found naturally in plants like blueberries, blackberries and red cabbages. Scientists believe antioxidants may help people fight against some illnesses. But tomatoes naturally only have a small amount of antioxidants in them.

British scientist Cathie Martin has been working on developing purple tomatoes for years. She wanted to see if she could create tomatoes with lots of antioxidants by changing the DNA of a tomato plant.

Dr. Martin added two genes from a plant called a “snapdragon”. Soon her plants were producing small purple tomatoes with lots of antioxidants. Even better, the tomatoes remained fresh almost twice as long as normal tomatoes.

Dr. Martin and some other scientists created a company. The company tested its tomatoes on mice that were likely to get cancer. The mice who were fed the purple tomatoes lived about 30% longer than the mice who were fed common tomatoes. Though that’s good news, tests on mice don’t always show what influence on humans will be like.

In recent years, Dr. Martin and her company have been working to get the agreement to grow and sell the purple tomatoes in the US. On September 7, the US government agreed. Dr. Martin and her company plan to introduce the tomatoes at farmers markets across the US in 2023. They also hope to sell the seeds to people who want to grow their own.

5 . ① Going to the cinema is fun. However, in a time when technology has afforded us home video streaming services such as Netflixhy and Hulu, many people choose to stay at home to have fun. And they believe cinemas are going to have problems. Though those services might have a bad influence on the cinemas, I don’t believe the cinemas are going away anytime soon.

② As we all know, staying at home to watch films can save your money because the tickets for cinemas aren’t cheap. Besides, you can lie comfortably on a big sofa to watch films. And generally you can watch films for as long as you want. And you don’t need to worry that others will be angry when you laugh aloud.

③ But the cinema has the low lighting, the big screen, the surround sound etc. War movies especially benefit from being watched in cinemas. You can experience the war better and more closely. As well as war movies, action movies and superhero movies are also much better when seen on the big screen.

④Besides, you can enjoy the time with your friends and family when going to see a good movie. Therefore, you’d better not just watch a movie at home and then go to bed. you can hang out with your friends and share your latest news face to face based on going to see a movie together.

⑤Anyway, we are lucky enough to live in a time that benefits people who love to go out and those who love to stay at home. Netflix and other services will always be there for those who prefer to stay at home. But going to the cinema offers better experience, and it helps cinemas create more jobs. It’s a win-win. So why not see a cool movie at your local cinemas?

How to read a book is written by Charles Van Doren and Mortimer J. Adler, which is called the Bible in reading.

The writers give some tips to help people how to read a book correctly.

Firstly, reading is a positive way. The more you want to read, you more you get. Someone will get tired when reading books, for they pay little attention on the book.

Secondly, reading includes many parts. Reading is from basic reading, reviewing reading, analyzing reading to subject reading. Analyzing reading is the most important step. “What is the book talking about?” “How did the writer talk about the book?” “What is the relation between you and the book?” and so on.

What’s more, reading is a long process. When you read an important part, it is better to analyze the deep meaning that the writer wants to tell.

Located at the foot of Datang Mountain in Changping District of Beijing, the China Aviation Museum is Asia’s largest museum displaying aircraft relics. The collection has about 200 aircraft of over 100 types and more than 700 examples of weapons and equipment. You can see some research materials and participate in many aviation activities in person.

Its mark which is up to 9 meters high is the first thing you will see when you walk into the China Aviation Museum. It is a milky white pillar holding a white single-seat light fighter plane which appears to soar in flight.

The China Aviation Museum is divided into three large exhibition areas: Cavern Exhibition Hall, Open-air Exhibition Area, and Integrated Hall.

The Cavern Exhibition Hall is in the south of the mark. In this hall, you can get a good knowledge of the world’s great aviation treasures from ancient to modern aircraft and equipment. These exhibits are placed on two sides in time sequence. The right side not only exhibits aircraft which are famous in Chinese aviation history, the left side is a series of modern aircraft produced by China.

As you walk to the north from the mark, you cannot miss the Open-air Exhibition Area. The Hero Avenue runs through it and divides the area into two parts. There is an artificial lake on the left of the Hero Avenue. On the southern side of the lake planes which were used specially for great people are displayed. The right side of the Hero Avenue exhibits fighter planes, radar and helicopters.

All the way down to the Hero Avenue lies the Integrated Hall. In this hall it displays 28 real aircraft, over 550 models of various aircraft, missiles, antiaircraft artillery, radar etc, more than 200 pieces of small cultural relics, 20 audio and video demo tablets, 12 sand table scenes and 1850 pictures and photos. On the west side of the Integrated Hall lays a CS field camp, where you can have an unforgettable experience.
