3 . Spanish artist Pablo Picasso (1881—1973 ) was one of the greatest artists of the 20th century. It was said that everything his brush touched turned to gold. But in truth, his works could be worth more than any precious metal. Picasso created more than 20,000 works in his life, including two of the world's 10 most expensive paintings.

Between 1907 and 1913, Picasso and his colleague Georges Braque started a revolution(革命) in painting. Before that, paintings were like windows—they were painted to look as if they had depth. You could tell which objects were "close" to you and which objects were "far away". But Picasso and Braque didn't want to paint like that any more. To them, a painting wasn't a window to the world; it was marks and lines on a flat surface. Why, they thought, should an object like a guitar be shown only from one angle (角度)? A guitar can look very different depending on which angle one looks at it from. Their answer was to show all the angles. They broke the guitar up into pieces. Their style of painting is called cubism (立体主义).

But why did they feel such a need to change things? Well, the world around them was changing, too. Science was turning people's ideas upside down. Albert Einstein's theory proved that what we knew about time and space was wrong. The world was becoming different; artists needed to start seeing and painting it differently.

The famous and terrifying painting Guernica (1937) shows a terrible scene during the Spanish Civil War. In the painting, you can actually see the sky falling. Picasso couldn't have painted it without the skills he learned during his cubist period. Breaking a guitar up into pieces was his preparation for showing the world being blown to pieces.

Last Sunday I went to a animal hospital to help the doctors there. I arrived at the hospital early in the morning. And there were already much work to do: giving the pets food and water, and even giving them kisses on the heads.

At first, they looked at me with frightening eyes. A doctor says to them, "Don't worry, and everything will be OK." I washed a dog's hurt leg. I worked careful to make sure I didn't hurt him. I wished he could know we were just trying help him. It was a long day and the work made me tired, and I was very happy. I knew I loved animal. And the animals knew I loved him. They enjoyed about my care with love!

7 . Do you like running enough to make it a habit? Temey Wolfgram does; she has made running a lifelong career and isn’t stopping.

In February, the 16-year-old from Woodbury High School, Minnesota, US, competed at the 2020 US Olympic Trials. She finished the marathon (42,J95 km) with a tune of 2:42:47 as the youngest competitor in the race and ranked 76th out of 390 runners.

Then, in November, Wolfgram, who turned 17, broke the Women's American Junior marathon record with her time of 2:31:49. The old record was 2:34:32, which had stood since 1984. During the run, Wolfgram once hit a wall pretty hard, but she overcame it to finish. ^“I guess I can say I gave it my all,” she told Runner's World. “When I finished, all I was thinking was that I was super happy,” Wolfgram said.

This was only her third marathon. In 2018, when Wolfgram was 15 years old, she ran her first marathon just because she wanted to see if she was capable of doing it. “I believed that I would get faster as the distances got longer... and I'm still glad that I did it.”

When preparing for that first marathon, she ran up to 120 miles （about 190 kilometers） per week. Although her parents didn't have any background in running, they helped Wolfgram train. At first, her dad would take her out in the morning and run about 13 miles. The distance would gradually increase each day. On top of her runs in the morning, she would do cross-country practice after school.

Next, Wolfgram will think about attending the Olympic Games in 2024 after it's scheduled.

Cities are diverse ecosystems, and a large number of species share our urban areas. As our city spreads, we need think about     1     it is like for other species to have human neighbors.

Because cities     2     (build) for humans, they do not always provide suitable habitats for wildlife. For example, most city parks are kept neat and tidy so that humans will find them     3     (pretty) than before. But when we cut grass or plant flowers, we destroy natural habitats.

When a bridge in Austin, Texas was repaired, engineers added small gaps running along the length of its bottom,     4     made a good home for bats, and soon the bridge was the home of thousands of bats. At first, people were afraid     5     the bats. Now, they have come to value     6     (they) winged neighbors. The bats are a tourist     7     (attract), and they eat lots of bugs every night.

There are also structures built with the objective of     8     (bring) wildlife into the city. The Beijing Olympic Forest Park is a good example. The park     9     (use) native plants and created open, natural spaces for wildlife. The result is a zone where over 160 species of birds can move about     10     (free). If we learn to share our space, we can become better neighbors to the wildlife around us.

Ladies and gentlemen,

I'm honored to stand here and present my speech.

Thanks for your listening!

10 . Will human beings find intelligent alien (外星的) life anytime soon? Probably not, according to theoretical physicist Stephen Hawking.

Hawking made the prediction during the Breakthrough Starshot announcement in New York City on April 12. At the news conference, Hawking, along with Russian billionaire sponsor Yuri Milner and a group of scientists, detailed a new project that aims to send a large number of tiny, wafer-size (薄饼大小的) spaceships into space to the neighboring star system Alpha Centauri (半人马座阿尔法星).

If these tiny spaceships travel at 20 percent of the speed of light, they'll be able to reach Alpha Centauri in just 20 years, Milner said. Once there, the spacecraft will be able to do a 1-hour flyby of Alpha Centauri and collect data that's impossible to gather from Earth, such as taking close-up photos of the star system, studying space dust molecules (分子) and measuring magnetic fields (磁场), said Avi Loeb, chairman of the Breakthrough Starshot Advisory Committee and a professor of science at Harvard University.

In addition to learning about space technology, the audience wanted to hear about aliens--specifically, when scientists might find them.

Hawking took questions from reporters in advance so that he would have time to prepare his answers.

Hawking has famously predicted that intelligent aliens might threaten humankind. Indeed, when asked about what Earthlings should do if we came across intelligent alien life, he said, “We should hope that they don' t find us.”

Other researchers at the conference offered a more optimistic view of alien life.
