3 . The Oresund Bridge connects two countries—Denmark and Sweden. This bridge is about 16 km long. It has a bridge over the sea, a tunnel under the sea and a man-made island in the sea. Tourists from the Denmark side need to go from the tunnel-level to the bridge-level on the island.

It took over four years to build this bridge. When it opened on July 1st, 2000, a large number of people went to have a look. They were surprised at its beauty. Now it is still one of the world’s most beautiful bridges, ▲ —people have to pay $52 for passing it! About 6,000 tourists go through the bridge every day and about 8 million people pass the bridge by train each year. Since 2000, a total of more than 12,000 cars and 50 thousand people cross it daily or it is about 4.5 million cars and 19 million people yearly!

The traffic across Sweden to Denmark rises for about 11% a year, and the bridge is possibly fully paid in 2035.

The Oresund Bridge has a great influence on the 3.5 million people in the Oresund area. It makes their people’s lives easy and of course the economy in this area will grow fast in the future.

Imagine you know that you’re dreaming while you’re asleep. You can try every food on the planet for free, travel around the world, hang out with famous people or lost loved ones, and maybe even have an interesting conversation with your dog. All of this may happen once you learn how to have lucid dreams.

Some people have lucid dreams naturally, while others need to practice. There are a few things that you can do to help increase your chances of experiencing a lucid dream. Keeping a dream diary is a great first step for anyone who wants to learn to have lucid dreams. But what next? The key to lucid dreaming is knowing that you are in a dream. To do that, most people need a “reality check.”

For example, you might try pressing your finger against a wall to see if you are dreaming. If you are not, the wall would stop your finger. In a dream, however, your finger might simply pass through the wall. Getting used to doing reality check while awake may help make it easier to do it while you are asleep.

Besides, scientists are developing technology to help people have lucid dreams. For example, Curzio Vasapollo invented a device called ZMax, a headband that can monitor eye movements and body movements to help people have a lucid dream.

Why would someone want to have lucid dreams? As it turns out, lucid dreaming can have many advantages. Alix Generous, a young woman living in her own world, said in her TED talk, “I love lucid dreaming because it allows me to be free and live a life I wish for.” Also, Lucid dreams may encourage creativity. For example, British American filmmaker Christopher Nolan got ideas from his own lucid dreams when he wrote the 2010 sci-fi movie Inception.

However, some studies suggest that lucid dreams may be bad for people’s health. In lucid dreams, people need to wake up during the night, so they may not have enough sleep if they do it several times every night, day after day.

What do you think? Would you like to try a lucid dream?

One of the best things to do in London, is a classic British pub quiz! The interesting entertainment of quiz nights always include: pictures, a music round and creative challenges so that everyone feels they can take part in. Pub owners say they hold quiz nights because everyone drinks like fish, so it is good business for them.

How does the quiz work? A quiz master is in charge of the quiz and reads questions out loud. The questions are about things they usually don’t pay attention to or “trivia”. For example, you may be asked to answer what the oldest national park is in England. People answer questions in teams. There are usually several rounds and a quiz can go on for 2 to 3 hours!

The quiz covers different topics, including history, geography, science, sport, TV, music and more. In a recent survey, 1,000 people from all walks of life answered the pub quizzes on the Internet. More than half of the people didn’t know the answer to the question: “How many countries make up Great Britain?” About eighty percent people had no idea of the question: “What is the world’s largest desert?”

To win the pub quiz, you need to study. For example, make sure you know the names of the winners of sport matches and TV shows. Besides studying it’s also very important to choose your team. Try to have a mix of men and women, and no more than five people. Once you get your team together, always trust your first answer, don’t think about it too much.

In some pubs if you take part in the quiz, you can get free drinks. But if you’ve paid to be in the quiz, there is usually a prize. Most people only go for the fun of it!

6 . On March 14, Bai Xuesong, a guide at the Beilin Museum in Xi’an, northwest China’s Shaanxi province, hosted a live broadcast displaying the collections at the museum.

Bai has become a hit on the Internet ever since he started giving tours of the museum collections through live streaming videos on February 23. After viewing his broadcasts, many netizens expressed a desire to visit the museum when it reopened after the COVID-19 outbreak.

It is estimated that more than 30 museums in China, including the National Museum of China and the Dunhuang Academy China, have hosted live broadcasts on online platforms during the epidemic, each gaining over 10 million viewers in one day. The Gansu Provincial Museum, one of the museums that has been exploring online platforms and using them, owned as many as 900,000 viewers at one point in its live broadcasts, more than half of its total viewers last year, according to the deputy curator(副馆长)of the museum. As a result, the number of fans of the official online store of the museum on the e-commerce platform Taobao has grown to 25,000, with sales of related products seeing a huge increase.

“Cooperation between museums and Internet platforms is beneficial to both sides,” said Huang Yang, vice professor with the cultural heritage and museology (department of the Nanjing Normal University). He said that while museums need to use live broadcasts to spread culture, Internet giants need the resources that museums possess to provide high-quality content for users. ▲ .

8 . It looks like a steak. It cooks like a steak. And according to the scientists who made and ate it, the thick and juicy meat smells and tastes like a steak. But appearances can be deceptive. Unlike any steak found on a menu or store shelf today, this one didn’t come from an animal.

Scientists printed it with a bioprinter, a new kind of 3D printer. The difference is that this type uses cells as a form of living ink. “The technology involves the printing of actual living cells,” explains biologist Neta Lavon, who helped develop the steak. Those cells are grown in a lab. They arc given nutrients and kept at a temperature that lets them keep growing. Using real cells this way, she says, is a real innovation over earlier “new meat” products. This allows the printed product to look, smell and taste much like a real steak.

Researchers call this meat “cultured”. Interest in it has grown in recent years, partly because the technology shows it is possible. Supporters say that if meat can be printed, then no animal would need to lose its life to become human food.

But don’t look for these products on the store shelves just yet. Making meat this way is much harder—and therefore costs more—than raising and killing an animal. “The technology will need to reduce the cost greatly before cultured meat will be widely available,” says Kate Krueger, a cell biologist in Cambridge, Mass.

One of the most expensive parts, says Krueger, is the cell-growth medium. This mix of nutrients keeps the cells alive and dividing. The medium contains expensive ingredients called growth factors. Unless the cost of growth factors drops, says Krueger,“cultured meat can’t be produced at comparable prices to animal meat.” If scientists can find lower-cost methods, this technology may stand a chance of giving beef without the moo.

We use emojis on Facebook, Twitter, and other social media platforms every day. But do you know there’s a World Emoji Day? Well, it’s a holiday held in July every year!

The holiday was created by Jeremy Burge as a way to popularize the usage of emojis. He also set up Emojipedia, a website where users can learn what emojis mean and how to use them. Since 2014, Emojipedia has celebrated World Emoji Day on July 17 because the date is shown on the calendar emoji on iPhones.

Invented in Japan in February 1999, emojis were first introduced to the world in 2011 by Apple in their iPhones. They were only pictures at the beginning, but now some big tech companies have added sounds into their emojis and Microsoft says 3D emojis will come out later. We usually use emojis when we are feeling lazy or at a loss for words. ▲. One court   judge in England used a smiley face emoji in a document to make it easy to explain the court’s decision to children.

Celebrating Emoji Day is fun while offering many possibilities for creativeness. For example, each year, Facebook and Twitter celebrate the World Emoji Day with various events online. It’s time to vote for your favorite emoji or create your own emoji. You can even take up the challenge to communicate only by using emojis for a whole day.

Emoji Day is a good time to spread the fun to everyone around us! On that day, we show our emotions, ideas, and thoughts happily with the help of emojis. According to experts, this holiday might help develop emojis into a new type of language.

10 . People begin to worry about the support capacity(能力) of the earth. There may be only standing room for each person in the future.

Lima’s population was 5.7 million in 1985 but it grew to 9.1 million in 2000. Tianjin’s was 7.9 million in 1985. In 2000, it boosted to 9.7 million. Such cities as London, Osaka, Moscow, Beijing, and Teheran are having a similar population growth. Shanghai, New York and St Paulo see a faster population explosion(爆炸). Tokyo had 18.8 million in 1985. In 2000 it changed into 20.2 million. Mexico city had 17.3 million people in 1985. But in 2000, its population reached 25.8 million.

What does the population growth mean? It means greater pressure for the earth. If the government doesn’t take any action to control the population, we would have only standing room by the end of the 21^st century.
