【推荐3】The eyes are the windows of the soul (心灵). Having a pair of bright, clear eyes is very important, so we should protect our eyes throughout our lives.

    1    

Don’t read while lying down or walking. Relax after every hour of reading. Keep a distance from the TV set when you watch TV and give your eyes a rest every 30 minutes. Don’t stare at (盯看) the sun or try to read in the darkness.     2     This can damage your eyes easily.

Get your eyes checked often.

Not many people have this habit, but it is necessary. If you feel that there is something wrong with your eyes, get them checked quickly.     3    

Rest your eyes whenever you can.

You can close your eyes for a few seconds or look into the distance for one or two minutes. A small break will relax your eyes.     4    

Besides, be careful when you choose your glasses.     5     Make sure your glasses are right for you. If you don’t feel right, get your glasses changed.

However, he can play very difficult musical pieces by musicians such as Chopin and Beethoven just a few minutes after he hears them. He learns a piece of music by listening to it in parts. Then he thinks about the notes in his head. Two years ago, he played his first piece Moonlight Sonata (奏鸣曲) by Beethoven. He surprised everyone around him.

Amazed that he remembered this long and difficult piece of music and played it perfectly, his teachers say Samuel is unbelievable. They say his ability is very rare, but Samuel doesn’t even realize that what he can do is special. Samuel wanted to become a lawyer as it was the wish of his parents, but music teachers told him he should study music instead. Now, he studies law and music.

Samuel can’t understand why everyone is so surprised, “I grew up with music. My mother played the piano and my father played the guitar. A bout two years ago, I suddenly decided to start playing the piano, without being able to read music and without having any lessons. It comes easily to me — I hear the notes and can bear them in mind — each and every note,” says Samuel.

Recently, Samuel performed a piece during a special event at his college. The piece had more than a thousand notes. The audience was impressed by his amazing performance. He is now learning a piece that is so difficult that many professional pianists can’t play it. Samuel says confidently, “It’s all about super memory — I guess I have that gift.”

However, Samuel’s ability to remember things doesn't stop with music. His family says that even when he was a young boy, Samuel heard someone read a story, and then he could retell the story word for word Samuel is still only a teenager. He doesn’t know what he wants to do in the future. For now, he is just happy to play beautiful music and continue his studies.

My high school is very big and those 4 minutes to go from one class to another really isn’t a lot of time. Today I had to go from one end of the building to the other to get from science class to math class. I wanted to go to my locker (储物柜) first and leave my science book there, but that took time. I was worried about being late, and I was. The math teacher said, “Just be on time tomorrow, or you’ll have detention(放学后留校).”

After math, I went to art class. I like my art class a lot because I get to create things. The teacher there showed us how to make portraits(肖像). He explained, “A portrait is a way of communicating with a person. It does not just show how the person looks but what is important to understand the person.” We just did drawings today, but I know it’s going to be great. I like drawing.

I like my English class, too. I think the teacher is really supportive. Today we wrote about ourselves. The teacher said that we just needed to write what we thought, and we would pay attention to punctuation(标点) later. We could write a paragraph or a poem, and I wrote a poem about myself. I thought it was a good poem, and the teacher said I had used good images (意象) to communicate my feelings.

Lunch was very hurried. I arrived at the dining room with 12 minutes to eat. I sat with people I didn’t know, and everyone was eating quickly. After lunch I signed up for a computer club. I needed to learn how to use a computer well because my social studies teacher said it is the one skill we need in every class.

After a while my brother and some of my friends got out of the water because they felt uneasy. There was the smell of fish in the air, which could attract sharks. A few of us stayed, Finally, I saw my first big wave, but as I was about to hit it, two great white sharks attacked me.

It happened so quickly. One shark hit me, throwing me into the air; in a split second, it dragged me under the water. The shock stopped me from feeling pain. Under the water, another shark went for my head and shoulders but missed.

Perhaps surprised by the competition, the first shark lost its grip on me and the next thing I knew was that I was staring a shark straight in the face. It stared back at me for a few moments. Its mouth was wide open; I could see huge teeth and dark black eyes. After it passed, I swam to the surface as fast as I could.

When I got there, I saw my surfboard lying in front of me. As I climbed on, I saw that my right hand was hanging off. I was losing blood quickly. When surfing, there is always the fear in the back of your mind of sharks. Now it was real. I was shaking, crying and panicking, realizing that I could die. I tried all my hardest to swim back to the shore.

Eventually, I made it to dry land. I felt relief. Someone tied my arm to slow the bleeding and my brother rushed me to the hospital. The surgeon managed to save my fingers.

That day changed my life, but it hasn’t stopped me from surfing. I started a surfing school to teach the sport to others. I was more afraid of sharks before my attack. Now I’m just grateful to be alive.
