Lily loved school. However, there was one class Lily worried about more than any other—art. She didn't know why she just wasn't any good at drawing, painting, or cutting.

Ms. Clay, the art teacher, stood at the front of the room. "Class, next Friday our school is going to have an art competition," she announced. Ms. Clay was a great teacher, and Lily liked her a lot. But this announcement made Lily nervous. "Everyone in the school will create a piece of artwork to show in the library. You can use the different types of artwork we have been studying." Ms. Clay was quite excited when she spoke while Lily found herself sinking lower in her chair.

Lily had the whole weekend to work on her project, but she could not think of anything to do. On Monday, Lily felt frightened, so after school Lily asked Ms. Clay if she could write an art paper instead of doing an art project.

"I understand this project scared you, Lily," Ms. Clay said. "Just remember, you can create any kind of art you want." Ms. Clay smiled at her. "Art is a person's way of expressing his or her feelings—it isn't always painting, drawing, or cutting. I know you will think of something very creative, and I can't wait to see it."

When Lily arrived home, she took out a piece of paper and a pencil. She remembered Ms. Clay's words. "Art is a person's way of expressing his or her feelings." Lily wrote the word "terrified" on her paper. She crumpled (揉皱) the paper and threw it to the side of her desk.

Then Lily stared at the crumpled ball. Suddenly an idea struck her.

Paragraph 1：

Why not create something out of crumpled paper?

Paragraph 2：

On Friday, Lily carefully carried her project into the library.

The light from the campfire brightened the darkness, but it could not prevent the damp cold of Dennis's Swamp (沼泽地) creeping into their bones. It was a strange place. Martin and Tom wished that they had not accepted Jack'sdare. They liked camping, but not near this swamp.

"So," Martin asked as they sat watching the hot coals. "How did this place get its name?"

"Are you sure you want to hear it? It's a scary story," warned Jack.

"Of course!" cried out Tom. "If there were anything to be scared of, you wouldn't have chosen this place!"

"Ok, but don't say I didn't warn you," said Jack, and he began this tale.

"Way back in time, a man called Dennis tried to start a farm here. He built that cottage over there to live in. In those days, the area looked quite different — it was covered with tall trees and the swamp was a crystal-clear river. After three hard years, Dennis had cleared several fields and planted crops. He was so proud of his success that he refused to listen to advice.

"‘You are clearing too much land,' warned one old man. ‘The land is a living thing. It will hit back at you if you abuse it. '"

"‘Silly fool,' said Dennis to himself. ‘If I clear more land, I can grow more crops. I'll become wealthier. He's just jealous!'"

"Dennis continued to chop down trees. Small animals that relied on them for food and shelter were destroyed. He was so eager to expand his farm that he did not notice the river flowing slowly towards his door. He did not notice salt seeping to the surface of the land. He did not notice swamp plants choking all the native plants."

"What happened?" Martin asked. It was growing colder. He trembled, twisting his body closer to the fire.

"The land hit back — just as the old man warned," Jack shrugged. "Dennis disappeared. Old folks around here believe that swamp plants moved up from the river and dragged him underwater. His body was never found."

"What a stupid story," laughed Tom. "Plants can't …" Before he had finished speaking, he screamed and fainted (晕倒). The other two boys jumped up with fright, staring at Tom. Suddenly, they burst out laughing. Some green swamp ivy (常春藤) had covered Tom's face. It was a while before Tom could appreciate the joke.

I'm standing on Rio's beach, one of the most famous 1 of sand. In this lively, multicultural country, the beach is not just a place;it's a state of mind—a way of thinking and living. 

Every Brazilian has his or her own ideas of the perfect beach, 2 to tell you where to find it. I'm happy to take their advice but my ultimate goal is to find my own dream beach. First, I go to Prainha's beach 3 by a row of perfect palm trees, moving softly in the ocean breeze. Its beauty is magnificent-its perfect graceful lines are like something in a 4 . But for me, it's somewhat too perfect. I am searching for something a bit 5 . 

I continue my search heading north to a legendary beach: Jeri. As an international destination, it attracts visitors from Tokyo to Toronto. Luckily, Jeri hasn't been 6 by tourists mostly because of its isolated(偏远的)location—at least five hours from any airport. I take a beach buggy(沙地车), driving for three hours. The boats lie on their sides while nets 7 to dry on lines between fishermen's houses. Peaceful and beautiful! How can it possibly get any better? I 8 . 

My final stop is the islands of Fernando, 9 a few hundred kilometers out in the Atlantic. They once were used as a prison and later by the army. Today, they are a national park and UNESCO World Heritage Site, 10 with birds and sea life. The beach there is a perfect 11 of sand, sea, and sky. The water is pale blue and warm, alive with colorful fish, 12 , and other marine life; the sand is the color of 13 . In the rocks and strong winds that 14 come in from the Atlantic, there is the wilderness I was seeking. Finally, I've found the beach of my dreams. I 15 my toes in the sand deeply and imagine I can hold on to this place forever.

"I'm going to play basketball, Daddy." Lauren flew into my arms when I came in from work. "That's 1 , honey," I replied naturally. I thought she meant outside the house—on the driveway. Into the kitchen, my wife Helen's silence indicated I had 2 something. After a while, she spoke slowly, "Lauren is joining the girls' high-school basketball team."

I 3 my girl's sportsmanlike courage, but 4 was still in my stomach. Lauren was only just 1.55m tall. 5 legs and a heavy body were surely a(n) 6 for her in playing basketball.

Finally, the game day arrived. Lauren and her teammates moved out. Their game faces seemed 7 to win. At first, though not playing, Lauren followed the movement on the court and 8 every play. I could even 9 her shout "No way!" when a referee made an unfair call against a teammate. Sitting on the sidelines, Lauren still enjoyed the game very much.

Suddenly, the announcer's voice boomed, "Number thirty-three, Lauren Wray, in." My heart 10 wildly. What if she got injured or other girls on the team made fun of her? But what I saw was that Lauren made every effort to keep pace with the others. Just before the end of the game, they 11 the ball to Lauren. She caught it. She shot. 12 she scored!

The audience began clapping and 13 . Lauren's brown eyes shone as she wiped her sweaty forehead. Lauren's uplifting spirits and impressive performance, wrapped in a small 14 , struck everyone greatly. I felt enormously 15 to have Lauren as my daughter.

The Ocean of Stars，a symphony（交响乐） concert by Suzhou Symphony Orchestra，was staged at the Jinji Lake Concert Hall in Suzhou，Jiangsu Province，on July 15，2023. {#blank#}1{#/blank#} part of the ongoing Hua Xia Music Festival hosted by Suzhou Symphony Orchestra，the concert {#blank#}2{#/blank#} （ conduct） by Chen Xieyang，featuring famous pianist Wu Chun.Chinese music {#blank#}3{#/blank#} （ work），including The Ocean of Stars and Mulan Psalm，all by Chinese composer Guan Xia，were performed.

As far as we know batteries are playing an important role in our life. We couldn't live without batteries. Why so? Batteries provide power for anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri (MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.

" To provide enough power, we need certain methods with high energy density (密度)", said Jae Kwon, assistant professor of electrical and computer engineering at MU." The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries."

Kwo n and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro/ nanoelectromechanreal systems(M/NEMS). Although nuclear batteries can cause concerns, Kwon said, they are safe.

" People bear the word‘ nuclear' and think of something very dangerous," he said," However, nuclear power sources have already been safely powering a variety of devices, such as pace- makers, space satellites and underwater systems."

His new idea is not only in the battery's size, but also in its semiconductor(半导体). Kwon's battery uses a liquid semiconductor rather than a solid semiconductor.

" The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor, Kwo n said," By using a liquid semiconductor, we believe we can minimize that problem."

Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwo n is working to build and test the battery. In the future, they hope to increase the battery's power, shrink its size and try with various other materials. Kwo n said that battery could be thinner than the thickness of human hair.
