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.

As I prepared for my Level 8 Royal Conservatory of Music piano exam, memories of previous disappointing marks filled me with dread and anxiety. The mere thought of booking the exam made me feel completely strained. However, fate had other plans in store for me.

Just when I thought things couldn't get any worse, my trusty 10﹣year﹣old electric piano malfunctioned. The middle C note played as an F﹣sharp, and multiple other keys were out of tune.

Despite my distress, my father refused to buy a new piano and instead urged me to be more resourceful. Initially, I was at a loss without my beloved electric piano. But after struggling for a few days, I was determined to find every available piano room on campus. After discovering hidden pianos in corners, I spent countless hours practicing. As my exam drew near

One day, while practicing in a piano room, one of my teachers walked in and offered me a mini exam. To my surprise, I found a place where I could be anyone.

Playing the piano became my escape from the anxieties of adolescence and allowed me to express myself freely. When it was time to play in front of the examiner, I no longer feared judgment. Instead, I only feared not being able to represent all my hard work. As the lights came on

Eventually, I received my mark. Not only did I achieve a rarely given "well done", but I also discovered a newfound appreciation for music. Whenever I feel discouraged, some lessons are best learned the hard way.

I hadn't got exercise lately and felt a bit dizzy. I was a little1 . One of my friends invited me to show up to see a2 that they said would help me feel better. Little did I know that I was about to see something I would never forget.

They introduced a young3 , Mr Patrick Henry Hughes. He was4 onto the stage in his wheelchair and began to play the piano. His fingers5 across the keys as he made beautiful music. He then began to sing as he played, and it was even more beautiful. For some reason,6 , I knew that I was seeing something special. Ten minutes later, someone came on the stage and7 a video of Patrick Henry Hughes.

Patrick was born with no eyes and a tightening of the joints which left him8 for life. Before his first birthday, he9 the piano. On his second birthday, he asked to play it. His father was10 . "We might not play baseball, but we can play music together. "

Today, Patrick is a11 at university. His father attends classes with him and he has made nearly all "A" s. He is also a trumpet player of a band. He and his father do it together — they12 all the band practices and the half-time performance in front of thousands of people.

But even more than his13 musical talent, it was Patrick's attitude to gratitude that touched me. I will never forget that night, that smile, that music, but most importantly, that14 attitude to gratitude. Gratitude can change your attitude,15 your life forever.

Humans act with purpose, but much is still unknown about how we become purposeful agents — that is, how we develop the ability to willfully make things happen. In a recent study to explore agency's mysterious roots, we tried to catch infants (婴儿) in the act of discovering their own agency, thereby revealing the process of agency formation.

Researchers place a baby into a cradle with a mobile suspended above. Then a scientist ties one end of a string to the mobile and the other to the infant's foot. Now if the baby moves, the toy will, too. By observing babies in this setup, scientists can watch as the infants learn and recall a simple cause-and-effect interaction: kick a foot and the mobile moves.

As predicted by the researchers, infants kicked significantly more when their foot was tethered (拴住) to the mobile than when it was not. However, when an experimenter pulled the string to make the mobile move instead, infants moved less than when the mobile was at rest. Furthermore, when we freed the babies' foot from the mobile, they kept on kicking at higher rate to make the toy respond — and were visibly frustrated when that did not happen.

Our observations also pointed to a notable pattern: The babies' initial movements consisted of twisting and pushing without clear direction. But once tethered to the mobile, the more intensely they moved, the more their attention was drawn to the effect their kicking had on it. At some point, the infants must have figured out that they had agency, thus the aimless movements became intentional action — a highly coordinated exchange between the tethered infant and the mobile.

The baby-mobile study emphasizes how understanding the relationship between an organism and its environment is essential to uncovering the origins of directed behavior. The experience of agency emerges only when an organism senses it is coupled to its environment. In this way of thinking, the interaction and relationship between the two are crucial for purpose to arise.

Zhang Guimei taught at a school during the day and took care of a children's home in her spare time. One day, Zhang met a teenage girl {#blank#}1{#/blank#} told Zhang that her family was too poor {#blank#}2{#/blank#} (afford) school fees. Zhang went to persuade her parents to allow their daughter to continue schooling {#blank#}3{#/blank#}, the parents refused Zhang. With the little girl lingering in her mind, Zhang tried to figure out how to help those poor local girls.
