13．The Fish I Didn't Catch
　　I still remember my first fishing trip as if it were but yesterday. It was a still, sweet day of early summer. I received the first fishing pole from my uncle's hand, and walked with him towards the (1)      .
　　My uncle, who knew where the best hangouts of fish were, kindly placed me at the most favorable point. I threw out my line as I had so often seen others, and (2)       eagerly for a bite. Nothing came of it. "Try again," said my uncle. Suddenly the bait (鱼饵) went down out of sight. "Now for it," I thought, "Here is a fish at last."
　　I made a strong pull, and brought up a tangle of weeds (一团海草). Again and again I cast out my line and drew it back (3)      . I looked at my uncle appealingly (可怜巴巴地). "Try once more," he said, "We fishermen must have (4)      . It took me a whole day until I got my first fish."
　　Suddenly something pulled hard at my line, and swept off with it into deep water. Jerking it up, I saw a big fish wriggling (扭来扭去) in the sun.
　　"Uncle!" I cried, looking back in uncontrollable (5)      , "I've got a fish!" "Not yet," said my uncle. As he spoke, there was a plash (泼溅) in the water, my hook hung empty from the line. I had lost my (6)      . My patience was used up.
　　I sat down on the nearest stone and (7)       to be comforted. Even my uncle promised that there were more fish in the river. He refitted my bait, put the pole again in my hands, and told me to try my luck once more.
　　"But remember, boy," he said, "Never show off catching a fish until he is on dry ground."
　　Though years have now passed, I have always been reminded of the fish that I did not catch. When I hear people show off a work as yet undone, I call to mind that scene by the river, and the wise warning of my uncle, "It's no use to talk too (8)       about anything until it's done."

15．Food for Good
　　In late August, after Hurricane (飓风) Dorian passed, José Andrés led a team of chefs and other volunteers to the disaster area, where they immediately set up kitchens and cooked 30, 000 meals a day. Because of their arrival, people affected by the disaster could eat fresh and healthy food, which was unimaginable in the past.
　　Before 2016, people in the disaster areas were only able to get prepackaged (预先包装的) meals, which usually didn't taste great and some of the food was even unhealthy. Andrés, who owns several popular restaurants in the United States, thought he could solve the problem. As a chef, he has the experience of creating delicious dishes and running a kitchen. What's more, he can even design dishes that suit the local tastes. So he set up the World Central Kitchen (WCK), an organization offering freshly made and healthy meals free for people affected by natural disasters.
　　Last year, WCK, with only 25 staff members, fed millions of survivors (幸存者) of 13 disaster areas around the world. How could they make it? Much of its work was done by volunteers from the disaster areas. The youngest volunteer once was even a 10-year-old girl who could run parts of the kitchen on her own. "She became a general in my army of volunteers," Andrés said. The girl and 20, 000 volunteers served almost four million meals after Hurricane Maria hit Puerto Rico.
　　"You know good food has great power. A hot meal expresses love, hope and humanity." Andrés said, "It is so important when people are deeply affected by disasters."

16．　　When you think of robots, what is the first thing that comes to mind? Do you think of science fiction movies like Star Wars, where robots of all shapes and sizes are part of daily life? The word "robot" itself comes from a play written in 1920 by Karel Capek. In the play, people create robots to do some everyday tasks.
　　Today, most robots don't look human. Modern robots take many forms and are good at many things, from sweeping the floors in your home to working in factories. They are even exploring the surface of the moon. But there is an interesting irony (讽刺) in the world of robotics which describes a surprising problem: What humans find easy is extremely complicated for a robot. However, what humans find difficult is pretty easy for a robot. For example, picking up clothes in a messy room is simple for people. But that kind of chore is very hard for a robot. Another example is the game of chess. People might find it difficult to win the game of chess all the time. But robots like Alpha Go can be programmed to play it very well.
　　This is because robots are very good at doing things in controlled environments. However, moving through a room filled with random (随机的) objects is hard for robots, along with picking up objects of different shapes and sizes without damaging them. In short, it is very difficult for them to deal with certain types of variables.
　　It turns out that one of the most difficult things to improve in robots is their ability to control objects. Luckily, great progress is being made in the development of robots. On the one hand, exciting developments in making human — like hands and legs are underway. On the other hand, the biggest progress might result from using virtual learning (虚拟学习) to "teach" robots through computer simulations (模拟). In this way, robots can "guess" what to do without an order when they meet unfamiliar things in the real world.
　　Soon, robots may be able to do those things that humans find simple. That means big changes in what robots can do and how they can help us with daily tasks. Robots might make movies a reality.

17．　　Though being a parent has never been easy, the Internet hasn't made the job any easier. Just how seriously are parents taking their role of monitoring (监控) their children's online behavior?
　　A new study from the Digital Future Project finds a sharp difference in parental ways of Internet supervision (监督). 70% of parents say they monitor their kids' online activity while on Facebook and other social media sites. In contrast, 30% of parents don't step in kids' online life because they trust their kids, don't want to show a lack of trust, don't know how to use social media sites or don't have time to. Such a divide is due to the fact that parents fall in multiple generations with many different types of parenting styles.
　　Many parents take a wide range of actions to monitor and police their teen's online behavior. Nearly six-in-ten parents say they often or sometimes check which websites their teen visits. 46% have password to log in their children's social media accounts. In order to combat unsafe websites surfing, some parents even download softwares such as Spectorsoft, which blocks, records and alerts parents by monitoring kids' Internet use.
　　However, parenting expert Gwenn Schurgin O'Keeffe, CEO of a parenting website PediatricsNow. com, advises against using such software as Spectorsoft unless it's a unique situation. "You do things because you love your kids and you want to protect them," she says, "But kids aren't these evil (邪恶的) creatures. Not trusting the online world should not be your only consideration."
　　With growing concerns, great efforts have been made globally to ensure Internet safety and quality for youngsters. The US government updated COPPA (the Child Online Privacy Protection Act) to increase protection for children's private information. Europe has not only given people "the right to be forgotten" on social media sites, allowing them to wipe their browsing history clean, but has also limited companies' access (进入) to personal information. "I like the idea," a user of PediatricsNow. com says, "Kids and teenagers are just experimenting. Until they hurt other people, they should be free to be a kid and learn about life."
　　Despite these efforts, government regulations (规章) are having a hard time keeping up as new websites pop up every day. Therefore, parents still have to step up and recognize they need to be involved in their kids' lives and find that happy medium. They have to stop being so disbelieving and give kids chances and the benefit of the doubt.

18．Hope for Tigers
　　In 2010, the World Wildlife Fund (WWF) brought bad news that the world tiger population had hit an all-time low. There were just 3, 200 tigers left in the wild, about half as many as there had been ten years before.
　　Now there's good news: Tigers could be making a comeback. There were about 4, 000 tigers in the world in 2019. In July, India, which has 70% of the world's tiger, announced (宣布) that its tiger population had reached nearly 3, 000. That's a 30% rise in just four years.
　　India's success was years in the making. In 2006, habitat (栖息地) loss made the number of India's tigers reduce to only 1, 411. So the Indian government decided to take a stronger plan of protection. Since its Wildlife Protection Act became law, India has given tigers a high level of protection.
　　Also, India's latest tiger amount was the work of thousands of scientists. They covered 150, 000 square miles of tiger habitat, using thousands of cameras to record the animal's movements. With the help of their research, India created 50 reserves (保护区), where tigers can spread out and hunt (捕猎).
　　It's when the big cats move away from the reserves that trouble starts. "When tigers leave protected reserves, they often run into local people. We cannot save wildlife without the cooperation of the people." says wildlife expert Shari Rodriguez. Therefore, India's government has been moving villages away from reserves. "In India, there is a lot of national pride in tigers. They are India's biggest attraction. Villagers benefit from jobs in the national parks or from selling art works to tourists."
　　But challenges remain for tigers all over Asia. They are hunted for their skin, and their teeth are sold as medicine. "They're still in danger," Rodriguez says. She draws hope from India's success, "This is a small, small victory in a long war against dying out."
