2 . You may have a house robot that can do housework for you. But is it so smart? Meet Laura, a robot in the National Library in Madrid, Spain, copying out the old books and writings in its collection. See Aurora, a headless dog-sized robot used to keep birds and other animals away at an Alaskan airport. Watch another 1.8 meter-tall legless robot called EveR6, waving its arms to guide musicians through a performance.

Those robots above require artificial intelligence (AI) (人工智能). AI is a computer system (系统) that can understand languages, make decisions and solve problems. AI can be taught skills using a process called machine learning. Humans give AI information such as books, photos or videos to train it. The more information it studies, the better it can do its job.

________. For example, when you watch TV, AI is watching you. It’ll know what your favorite is and suggest similar ones. In hospitals, AI is very good at suggesting treatments and can even invent new medicines. To cut down food waste, some schools introduce online systems for the students to choose meals ahead of time. In cities, AI is used to watch out for cars that make black smoke. It works together with the police and transportation teams to stop them and keep the air clean. AI can help us fight climate (气候) change by finding clever ways to reduce energy use.

Some people worry that AI will take away a large number of jobs and also fear that AI could develop out of our control and bring danger to humans. However, AI is expected to be a more powerful production tool that will help humans achieve more in less time. It is believed that the flying car will be made to offer an easier way out of the morning traffic jam (交通堵塞). Humans imagine AI might even find a way to solve the problems of our energy needs completely. Anyway, there is still a long journey for humans and AI.

Seven arctic wolves (北极狼) move smoothly across a frozen pool and begin to run after a thick piece office.

The three older wolves are _______ wildly, hitting the four young wolves and sending them rolling (打滚) on the frozen grass.

The theme parks in the world are popular because they have their own character IPs (知识产权), such as Mickey Mouse and Harry Potter. According to     1     research report, IP is the “heart” of a theme park.     2     (develop) China’s own IPs, some theme parks make good use of traditional Chinese culture, and others focus on films about Chinese     3     (story).

It is     4     (encourage) that the Chinese cultural industry (产业) has been taking a big step in creative works. For example, some famous theme parks have opened in Shanghai and Beijing     5     (recent). It’s happy to see that some Chinese culture has been welcomed in the parks.

Over the past few years, Chinese cultural IPs have often appeared     6     movies and TV dramas. For example, the Chinese film Chang’an San Wan Li became a success thanks to the Chinese ink paintings, ancient poems     7     high technology in it. Besides, Mulan, which     8     (produce) years ago, helped traditional Chinese cultured to be learned by the world.

Traditional Chinese culture     9       (provide) special experiences for the entertainment industry. The key lies in new ideas. With the help of high technology, China can develop     10     (it) traditional cultural IPs and it will have world-class theme parks in the coming years.

6 . The silence of the pond (池塘) was broken by the first cry: “Found something!” A swimmer ducked (扎入) into the water with a lifeline connected to a boat. Soon, she appeared, holding a bright blue glass bottle. It was passed to another, then into the boat.

On a fine Sunday morning in May, a team of 10 women over 65 years old, known as the Old Women Against Underwater Rubbish (OWAUR), looked for rubbish across Nova Pond in Scotia.

When the team returned, they joked about the trip. “We didn’t even know what it was,” one swimmer said with a laugh, showing an electronic lighter they had found. “We had to ask a young person.”

Part protection organization, part social club, OWAUR only accepted old women as its members. To improve the conditions of the ponds, the group made it its mission to take rubbish away from them. The idea of this group was from a moment of Sandy, a retired (退休的) reporter. As a lifelong nature lover, she liked swimming in ponds. However, the world of the pond, which was a little polluted, made her anxious. Then she came up with a slogan (标语):

“OVER 65, IF YOU’RE HEALTHY ENOUGH, IS THE AGE OF ACTION.”

Soon many people joined her. They found a sense of wonder at the pond cleanup moments. And their team could do a lot more than people might think.

When many people thanked OWAUR for what they had done, some questioned why they called themselves “old women”. “You should call yourselves the Mermaids (美人鱼) Against Underwater Rubbish,” they said.
