1 . The Golden Gate Bridge is a well-recognized landmark in the United States. It spans (横跨) the Golden Gate Strait — a mile-wide stretch of water that connects the San Francisco Bay to the Pacific Ocean. The Golden Gate Bridge is one of the most beautiful bridges in the world. It is also one of the tallest.

The idea for a bridge across the strait had been around for many years, because San Francisco suffered from its isolated location. Planning for the Golden Gate Bridge began in 1916, but the design underwent many changes before construction finally started in 1933.

Joseph Strauss was the chief engineer in charge of the bridge project. However, he had little experience with the construction of suspension bridges (吊桥). For this reason, other engineers, architects, and designers made great contributions to the design and construction of the bridge. For example, the bridge owes its art deco (装饰派艺术) style and distinctive orange color to the architects Irving and Gertrude Morrow. Charles Alton Ellis did much of the technical work necessary to build the bridge.

It was not easy to get the project started. Financing had to be found, and there was much opposition to the very idea of a bridge. The US Navy, for example, feared, that a bridge would block ship traffic. The Southern Pacific Railroad, which ran the ferry fleets (轮渡船队), feared competition from the bridge. Many experts did not believe that it would be possible to build such a long bridge under such difficult circumstances. There are strong currents and heavy winds on the bridge site, which made construction dangerous.

The construction of the bridge finally began in 1933. The construction work set new standards for safety — workers were among the first required to wear hard hats, and a safety net saved the lives of nineteen men while the bridge was built. The Golden Gate Bridge was completed in 1937, when the bridge was opened to pedestrians (行人). It was opened to cars one year later. The bridge was finished ahead of schedule and cost much less than originally budgeted.

Because the Golden Gate Bridge is the first sight for many people arriving in the United States by ship, it is sometimes called the “Statue of Liberty” for the West Coast.

4 . How to Travel with Your Friends Without Hating Them

The only thing better than a vacation with friends is a well-planned vacation with friends.     1     Choose your friends, destination and activities wisely and your group will enjoy a fun and memorable holiday-and start getting ready to plan the next one.

Not sure how to plan a trip with friends?

Choose friends you get along well with. You’ll be spending a lot of time with your travel companions, so think of people who have similar general travel habits and are flexible and relaxed.     2     Also consider how much you’ll be willing to compromise.

Decide on a date. Ask your friends when they can take time off from school or work.     3     The larger your group is, the harder it will be to find a time that works for all of you. Be patient and flexible and make a deal when you can.

Discuss a budget early on. Ask your friends to be open about how much you’re each willing to pay for the trip between travel, accommodation, food and entertainment costs.     4     For example, you could say, “I know it’s awkward, bat we should talk about a budget before we start planning everything.”

Pick a destination wisely. A key step in planning a fun trip with friends is picking the perfect destination. Big cities are an excellent pick, as there will likely be activities to suit everyone’s interests.     5     Consider the activities you want to do, sites you want to see and the amount of time you have to travel, as these factors will decide your destination.

5 . Traveling with family members can not only enhance the parent-child relationship, but also broaden the horizons and share happiness and memories. Take a trip with your family to one of the destinations below!

Yellowstone National Park

Kids will love watching Old Faithful, one of nearly 500 geysers (间歇喷泉) in Yellowstone, erupt, and there’s nothing like a hike for family bonding. Keep an eye out for wild animals, or visit the Grizzly & Wolf Discovery Center to guarantee some animal interactions. Hotels are expensive, so consider taking advantage of the park’s well-equipped campsites.

Orlando

Appealing, thrilling and fun, Walt Disney World Resort (度假村) is engineered specifically for families. Orlando also has a handful of other theme parks, including Universal Orlando Resort, where you’ll find The Wizarding World of Harry Potter, and Discovery Cove, an all-inclusive day resort, where you can swim and dive around the park’s coral reef.

Destin

Big Kahuna’s Water & Adventure Park(open seasonally)features waterslides and a lazy river, while the Gulfarium Marine Adventure Park is home to animals kids love, including dolphins and penguins. And if you’re looking for an adventure on the water, consider booking a boat tour at Henderson Beach State Park or Crystal Beach Park. Just don’t forget to pack your beach hat.

Anaheim

Anaheim, California has been home to Disneyland Resort since 1955. After catching up with Mickey and friends, visit Anaheim’s Adventure City Amusement Park or Knott’s Berry Farm Theme Park—another top amusement park in the U.S. And if you’ re in town during baseball season, you can catch a game at Angel Stadium.

6 . Scientists train AI to read human thoughts

Scientists have created a new tool that can turn people’s thoughts into words. It works by using an AI program called GPT-1 to translate brain activity words. In order to achieve this, scientists did a lot.

First, scientists got everything ready before the tests. They invited some volunteers. Each spent sixteen hours listening to stories in a scanner (扫描仪). They imagined the stories as they heard them, and the scanner recorded their brain activity. GPT-1 made connections between the ideas in the stories and the recordings of the listeners’ brain activity.

Then came the tests. The scientists did them in three different ways.

Test 1

The researchers played a new story. GPT-1 was only given recordings of the volunteers’ brain activity. But the words that GPT-1 predicted were very similar to the words in the story that they were listening to. The words weren’t exactly the same, but they often carried the same meaning. For example, when a volunteer was listening to a story about a woman who didn’t have a driver’s license, the program came up with this: “She hasn’t even started to learn to drive yet.”

Test 2

The scientists also carried out the test when volunteers imagined their own stories. “It really works at the level of ideas. The ideas are the same but expressed in different words,” says Alexander Huth, one of the scientists behind the study.

Test 3

The researchers showed the volunteers silent movies, with no spoken words at all. GPT-1 could still figure out the basic ideas.

After the tests, the scientists say that GPT-1 is the first AI program to turn what people are thinking into words without brain surgery (外科手术). The tool isn’t something that can be easily used today, mainly because of the size and the cost of the scanner. In the future, they believe, a similar but cheaper tool could help people who have lost the ability to speak because of an injury or disease.

The scientists say their tool can’t be used to “read people’s minds” without permission. The tool only works if the person wants to share their thoughts.

10 . After returing from his job as a cultural relics protection worker 10 years ago, Wang Yongxian kept his love for ancient Chinese architecture (建筑) through teaching.

Now aged 73, he still teaches a course named “Conservation and Restoration of Ancient Chinese Buildings” at a University in Shanxi province. His main interest is Dougong, a construction method that uses interlocking (紧密连接的) wooden pieces to form structures. The method is one of the most important features of ancient Chinese architecture.

Wang also started online classes to better explain Dougong to those who showed a strong interest in his course. Following a suggestion from his students, he became a vlogger using the account name “Dougong class”. The account is regularly updated with short video clips Wang produces himself. He is surprised that his classes are so popular on social media. The first six lectures on ancient Chinese buildings that he uploaded over a six-month period have received 1.6 million views.

To make it easier for newcomers to the subject to understand, Wang made a wooden Dougong model. Each part is marked with a number or name, and the model can be taken apart and put together, a process that Wang filmed and put online. Some viewers said that they had long been puzzled by Dougong structures, but finally understood how they work after watching the video of “Dougong grandpa”.

Wang said when he was young, the beautiful ancient temples in his hometown had ignited his interest in ancient wooden buildings and finally led him to turn his interest into a lifelong career. What makes him happy today is not only that the government set aside more money for the research and protection of cultural relics, but also that society is more aware of the importance of such work.

To his surprise, about 90 percent of his more than 100,000 viewers online are below age 30. That fact makes him more confident that as long as the story of Chinese ancient architecture is told in the right way, it can attract more people.
