Being a superhero to others
Ewan Drum has always liked superheroes. He likes how they help people. At age seven, he told his parents, “I want to dress up like a superhero and help the homeless. ” 1.Wearing his red superhero cape (斗篷), Ewan helped pass out 70 bag lunches to hungry people in a park in Detroit, Michigan. That’s how Super Ewan was born.
2.People donated(捐赠) money and supplies (供给物), and Ewan took them to those in need.
When someone donated jugs(大罐) of water, Ewan and his family drove their car to get even more. They took the water to Flint, Michigan, a city that had unsafe drinking water. Another time, a businessman donated six turkeys(火鸡) for Thanksgiving.3.“In the end”, he says,“we gave 64 turkey dinners to families all around Detroit.”
Ewan has a motto: Everyone can be a superhero to someone. At an event called the Hero Round Table, Ewan told the audience,“It’ s not hard to help people.You can keep some socks and food in your car to help people in need. You can help a neighbor with doing the garden. 4. .”
It' s been several years since Super Ewan started his task. Every month, he still visits the same park to hand out clothes, food, and supplies to people who are hungry or homeless ---his Super Friends. 5.

Alexa is a form of artificial intelligence, or AI for short. Many people start their mornings by asking Alexa for the weather forecast or the latest news. A device(设备) that houses Alexa can also play music from your favorite playlists, keep a shopping list, order takeout food, answer questions, send messages and even run “smart” home controls.
Training AI systems to respond to problems with human-like intelligence and learn from their mistakes can take months, or even years. Consider Alexa and similar software, such as Apple’s Siri. To do the tasks its human owners ask, these systems must make sense of and then respond to sentences such as, “Alexa, play my Ed Sheeran playlist” or “Siri, what is the capital of India?”
Computers can’ t understand language as it is spoken by people. So AI researchers must find a way to help humans communicate with computers. The technology used to get computers to “understand” human speech or text is known as natural language processing. By natural language, computer scientists refer to the way people naturally talk or write. To teach an AI system a task like comprehending(理解) a sentence or responding to a person ’s last move in a board game, scientists need to feed it lots of examples.
AlphaGo is an AI system designed by Google that has beaten a human champion, Lee Sedol, at the strategy(策略) board game Go. To train AlphaGo, Google had to show it 30 million Go moves that people had made while playing the game. Then AlphaGo used what it learned to analyze those plays as it played against different versions (版本) of itself. During this practice, the program came up with new moves---ones never seen in games between people.
1.What does the example of Alexa show?
A. AI may replace humans one day. B. AI is playing a role in our modern life.
C. AI has been widely used around the world. D. AI has totally changed people’s bad habits.
2.How do scientists train AI systems?
A. By testing them thousands of times. B. By teaching them almost everything.
C. By giving them quite a lot of tasks to do. D. By providing them with large amounts of data.
3.What can we learn about AlphaGo?
A. It has become very skillful and intelligent B. It is the most convenient AI system.
C. It avoids making any mistakes D. It just follows human orders
Nola (August 21, 1974 -November 22, 2015) was a northern white rhino who lived at the San Diego Zoo Safari Park near Escondido, California. At her death, she was one of only four remaining northern white rhinos in the world. The other three lived in Kenya. World Rhino Day, held on September 2, is to raise awareness(意识) of the less than 30,000 other rhinos left on Earth.
“Rhinos need our help today, not tomorrow,”Nola’s lead keeper Jane Kennedy said. “Last year we lost over 1,200 rhinos just in South Africa. If we continue to lose more than 1,000 rhinos a year, in 10 to 20 years all the rhinos on the planet will be gone.”
“Unfortunately, most animals are in danger of dying out because of humans,” Kennedy says.“ Humans have either poached animals, or because there are over seven billion of us, we’ ve taken up too much of the world’s resources ”. Poachers illegally hunt rhinos for their horns. They sell the horns for thousands of dollars per pound, to be used for art, jewelry, and decorations.Experts believe that one rhino is poached every eight hours.
In 1975, the San Diego Zoo Institute for Conservation Research started the Frozen Zoo, a program through which researchers have collected cell (细胞) samples from more than 8,000 different types of animals, including the northern white rhino. Scientists hope that by studying the rhino cells, they will get greater understanding of it, and will find ways to increase its numbers.
Jane Kennedy describes World Rhino Day as “a celebration of rhinos along with an awareness campaign for everybody across the world to know that rhinos need our help.”At the San Diego Zoo, children and adults are welcome to visit and speak with zookeepers to learn about rhinos. But you don’ t have to live in San Diego to celebrate World Rhino Day. It is observed around the world, with zoos and wildlife parks holding special events and programs to teach people about rhinos, and enable them to see the animals up close.

One Sunday, Nicholas, a teenager, went skiing at Sugarloaf Mountain in Maine. In the early afternoon, when he was planning to go home, a fierce snowstorm swept into the area.Unable to see far, he accidentally turned off the path. Before he knew it, Nicholas was lost, all alone! He didn’t have food, water, a phone, or other supplies. He was getting colder by the minute.
Nicholas had no idea where he was. He tried not to panic(惊慌). He thought about all the survival shows he had watched on TV. It was time to put the tips he had learned to use.
He decided to stop skiing. There was a better chance of someone finding him if he stayed put. The first thing he did was to find shelter from the freezing wind and snow. If he didn’t, his body temperature would get very low, which could quickly kill him.
Using his skis, Nicholas built a snow cave. He gathered a huge mass of snow and dug out a hole in the middle. Then he piled branches on top of himself, like a blanket, to stay as warm as he could.
By that evening, Nicholas was really hungry. He ate snow and drank water from a nearby stream so that his body wouldn’t lose too much water.Not knowing how much longer he could last, Nicholas did the only thing he could--- he huddled in his cave and slept.
The next day, Nicholas went out to look for help, but he couldn’t find anyone. He followed his tracks and returned to the snow cave, because without shelter, he could die that night. On Tuesday, Nicholas went out to find help. He had walked for about a mile when a volunteer searcher found him. After two days stuck in the snow, Nicholas was saved.
Nicholas might not have survived this snowstorm had it not been for TV. He had often watched Grylls’ survival show Man Vs. Wild. That’s where he learned the tips that saved his life. In each episode of Man Vs. Wild, Grylls is abandoned in a wild area and has to find his way out.
When Grylls heard about Nicholas’ amazing deeds, he was super impressed that Nicholas had made it since he knew better than anyone how hard Nicholas had to work to stay alive.
